Description

Technical Field

[0001] This invention relates to the field of electric vehicle cable soldering technology, and specifically to an automatic soldering machine for electric vehicle cables. Background Technology

[0002] The soldering quality of electric vehicle cables and terminals directly determines the conductivity reliability and operational safety of the electric vehicle circuit system. With the large-scale development of the electric vehicle industry, higher requirements are placed on the batch production efficiency, solder joint consistency and quality stability of cable terminal soldering. Some existing automatic soldering equipment relies on manual labor to complete the solder joint conductivity test and appearance inspection after soldering. Manual operation is not only inefficient, but also prone to misjudgment due to human fatigue and subjective judgment differences. There is a high risk that qualified products will be missed or unqualified products will flow into the next process. In order to solve the above problems, this invention provides an automatic soldering machine for electric vehicle cables. Summary of the Invention

The multiple fixing components are fixedly installed on the conveyor belt body and are evenly distributed along the movement direction of the conveyor belt. An inspection component, mounted on the frame of the conveyor belt, is used to inspect the soldering quality. Specifically, when the data detected by the detection component reaches the set value, the detection component controls the fixing component to discharge the cables and terminals in the fixing component. When the data detected by the detection component is lower than the set value, the fixing component drives the cables and terminals on it to move with the conveyor belt to the waste discharge area, and then releases the cables and terminals.

[0006] Preferably, the cable fixing part includes: The outer frame is fixedly installed on the conveyor belt body, and the upper side of the outer frame is provided with a clamping groove for fixing the cable. The inner diameter of the clamping groove is adapted to the outer diameter of the cable. The clamping groove has an opening on the side away from the conveyor belt body, and the size of the opening is smaller than the diameter of the cable. The outer frame is made of elastic material.

[0007] Preferably, the terminal fixing part includes: A fixed platform is fixedly installed on the conveyor belt body, and the fixed platform is made of an elastic material. Multiple snap-fit ​​connectors are mounted on the side of the mounting platform and are interference-fitted with the terminals for fixing the terminals to the mounting platform. The snap-fit ​​component is driven by the detection assembly to slide along the axis of the fixed platform.

[0008] Preferably, the snap-fit ​​component is made of an elastic material, and the snap-fit ​​component includes a main rod, which is slidably mounted on the side of the fixed platform, and a protrusion is fixedly mounted on the side of the main rod facing the axis of the fixed platform, and the protrusion is interference-fitted with the terminal.

[0009] Preferably, the detection component includes: The cable conductive part is installed inside the cable fixing part and is connected to the conductor inside the cable; A terminal conductive block is fixedly mounted on a fixed platform, with one end of the terminal conductive block in contact with a terminal and the other end extending through the side of the fixed platform to the outside of the fixed platform. Two conductive rods are installed on the two side walls of the conveyor belt frame, and the two conductive rods are electrically connected to an external continuity detector. The driving unit is connected to the cable conductive part and the snap-fit ​​component respectively, and is used to drive the cable conductive part and the snap-fit ​​component to discharge the cable and terminal inside the fixing component. When the fixing component moves between the two conductive rods, the cable conductive part and the terminal conductive block are electrically connected to the corresponding conductive rods.

[0010] Preferably, the conductive portion of the cable includes: A cable conductive block is fixedly installed inside the cable fixing part. One end of the cable conductive block passes through the outer frame away from the supporting part and extends to the outside of the outer frame. The other end extends into the clamping groove and is integrally formed with a clamping ring. The clamping ring has an opening, and the size of the opening is smaller than the diameter of the cable conductor. The clamping ring is connected to the driving part.

[0011] Preferably, the two ends of the clamping ring opening are folded in opposite directions, and the folded ends extend to the two side walls of the clamping groove opening and slide in connection with the groove wall of the clamping groove. The contact point between the folded ends and the groove wall of the clamping groove is on the same horizontal plane as the axis of the clamping groove. A fixing rod is fixedly installed on the folded end of the clamping ring. The end of the fixing rod away from the clamping ring extends to the outside of the outer frame through a through groove provided on the wall of the clamping groove, and folds to both sides to form a "T" shape.

[0012] Preferably, the driving unit includes: A connecting rod is slidably installed inside a slide groove and driven by an electric push rod installed inside the slide groove.

[0014] The beneficial effects of this invention are as follows: This invention achieves automated quality inspection and sorting of electric vehicle cables and terminals after soldering by setting up a conveyor belt, a fixing component, a detection component, and a drive unit. The fixing component can securely fix the cables and terminals and work with the conveyor belt to complete the flow. The detection component judges the soldering continuity quality by the electrical connection between the conductive part of the cable, the conductive block of the terminal, and the conductive rod. If it is qualified, the drive unit drives the fixing component to discharge the cable and terminal. If it is unqualified, the fixing component is released along with the conveyor belt to the waste discharge area. There is no need for manual inspection and sorting, which greatly improves production efficiency and reduces the risk of human error.

[0015] This invention achieves stable clamping of the conductor inside the cable through the setting of the outer frame and clamping ring, and enables the clamping ring to fit tightly against the conductor inside the cable. At the same time, it enables a stable electrical connection between the clamping ring and the conductor inside the cable, allowing for stable testing. Moreover, under the driving action of the drive unit, when the clamping ring releases the conductor inside the cable, it can expand the outer frame to open the opening of the clamping groove, releasing the cable and the conductor simultaneously, thus separating the cable from the cable fixing part.

[0027] 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, and 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.

[0028] This invention provides an automatic soldering machine for electric vehicle cables, such as... Figures 1 to 9 As shown.

[0029] Example 1: An automatic soldering machine for electric vehicle cables includes a conveyor belt 1, a base frame 2, a solder melting component, a support part for a fixing component, and a tensioning shaft 18. The conveyor belt 1 adopts a synchronous belt drive structure, and multiple fixing components are fixedly installed on its surface. The fixing components are evenly distributed at equal intervals along the movement direction of the conveyor belt 1, ensuring that each fixing component can pass through the solder melting component, the detection component, and the waste discharge area in sequence. The base frame 2 is a gantry structure made of aluminum alloy, which is fixedly installed on the two side frames of the conveyor belt 1 by welding. The solder melting component includes a solder wire feeder, a heating nozzle, and a miniature slide (the solder wire feeder, heating nozzle, and miniature slide are all existing technologies and are now widely used in various soldering robots, so they will not be described in detail in this invention). The miniature slide is slidably installed on the top crossbeam of the base frame 2 via a guide rail. The solder wire feeder and the heating nozzle are fixed on the miniature slide. The miniature slide can drive the solder melting component to move along the length direction of the base frame 2, thereby covering the connection position of the cable and the terminal during the sliding process, making the cable and the terminal more stable by soldering.

[0030] The fixing component includes a cable fixing part, a terminal fixing part, and a support part. The cable fixing part, terminal fixing part, and support part are all fixedly installed on the conveyor belt 1. The support part is located between the cable fixing part and the terminal fixing part. The upper surface of the support part has an arc-shaped groove adapted to the welding end of the cable and terminal. The inner wall of the groove is coated with a solder resist layer made of polytetrafluoroethylene. When the heating nozzle of the molten solder component melts the solder wire, the molten solder will drip onto the joint between the cable conductor and the terminal. The arc-shaped groove of the support part can limit the flow range of the solder, preventing the solder from overflowing into the cable insulation layer or the non-welding area of ​​the terminal. At the same time, the solder resist layer can prevent the molten solder from sticking to the surface of the support part, reducing the frequency of subsequent cleaning.

[0031] A tensioning shaft 18 is installed on the frame of the conveyor belt 1. The tensioning shaft 18 is a cylindrical shaft made of stainless steel. It is installed in the waste discharge area of ​​the conveyor belt 1 frame through a bearing seat. The outer circumference of the tensioning shaft 18 contacts the lower surface of the conveyor belt 1. By applying a downward clamping force to the belt, the conveyor belt 1 forms an outwardly protruding waste discharge area in this area. When the detection component determines that the product is unqualified, the fixing component will move to the waste discharge area under the drive of the conveyor belt 1. At this time, the fixing component releases the cable and terminal. The unqualified product slides from the surface of the arc-shaped belt under the action of gravity into the waste collection box below, realizing the automatic waste discharge of unqualified products. It works in conjunction with the flow action of the conveyor belt 1 to complete the waste discharge process.

[0032] When the testing component detects that the welding quality is qualified, the testing component directly discharges the qualified welded cables and terminals directly from the fixed component.

[0033] The detection assembly includes a cable conductive part, a terminal conductive block 8, a drive unit, and two conductive rods 9. The two conductive rods 9 correspond to the cable conductive part and the terminal conductive block 8, respectively, and are fixedly installed on the frame of the conveyor belt 1. The conductive rods 9 are connected to an external continuity tester through wires. When the fixed assembly moves with the conveyor belt 1 to the space between the two conductive rods 9, the cable conductive part contacts one of the conductive rods 9, and the terminal conductive block 8 contacts the other conductive rod 9. At this time, the continuity tester can judge the welding quality by detecting the resistance value of the circuit.

[0034] The conductive rod 9 is located between the soldering assembly and the waste removal area. Soldered cables and terminals first pass between two conductive rods 9 before moving to the waste removal area. The detection assembly is located on one side of the conveyor belt 1 (e.g., ...). Figure 2 As shown in the figure, after the test is passed, the fixing component can be loosened to release the cable and terminal. At this time, the qualified cable and terminal will fall off automatically under the action of gravity.

[0035] Example 2: The cable fixing part includes an outer frame 3, a clamping groove 4, a cable conductive block 10, a clamping ring 11, and a fixing rod 12. The outer frame 3 is made of nitrile rubber (which is elastic and heat-resistant) and is fixedly installed on the conveyor belt 1. The upper side of the outer frame 3 has an integrally formed clamping groove 4 for accommodating the cable. The inner diameter of the clamping groove 4 is set according to the outer diameter of commonly used electric vehicle cables. The clamping groove 4 has an opening on the side away from the conveyor belt 1. The size of the opening is smaller than the inner diameter of the clamping groove 4. When it is necessary to fix the cable, the operator can squeeze the cable into the clamping groove 4 with external force. The elastic material of the outer frame 3 will deform due to the compression. After the cable is completely inserted into the clamping groove 4, the deformation of the outer frame 3 will return to its original state. The opening of the clamping groove 4 will clamp the cable to prevent the cable from falling off during the soldering process.

[0036] The cable conductive part includes a cable conductive block 10, which is made of copper (with excellent conductivity). It is fixedly installed inside the cable fixing part by embedding. One end of the cable conductive block 10 extends through the outer frame 3 away from the support part to the outside of the outer frame 3 for contact with the conductive rod 9. The other end extends into the inside of the clamping groove 4, and the clamping end is integrally formed with a clamping ring 11 for clamping the cable conductor. The clamping ring 11 is also made of copper. It has a semi-circular structure and an opening. The size of the opening is smaller than the diameter of the cable conductor. When the cable is fixed in the clamping groove 4, the internal conductor of the cable is exposed and inserted into the clamping ring 11. The elastic deformation of the clamping ring 11 will make the ring tightly fit the conductor surface, ensuring a stable electrical connection between the two.

[0037] The two ends of the opening of the clamping ring 11 are folded in opposite directions to form folded ends. The folded ends extend into the two side walls of the opening of the clamping groove 4, and the folded ends are slidably connected to the groove walls. Under the elastic force of their own, the two side walls of the clamping groove 4 apply a clamping force towards the cable conductor to the folded ends of the clamping ring 11, so that the connection between the clamping ring 11 and the cable conductor is tighter. The contact points between the folded ends and the groove walls of the clamping groove 4 are all on the same horizontal plane as the axis of the clamping groove 4. A fixing rod 12 is fixedly installed on the folded ends of the clamping ring 11. The end of the fixing rod 12 away from the clamping ring 11 extends through the through groove opened in the groove wall of the clamping groove 4 to the outside of the outer frame 3, and this end is folded to both sides to form a "T" shape structure. The "T" shape structure can prevent the fixing rod 12 from falling out of the through groove.

[0038] During welding quality inspection, the end of the cable conductive block 10 extending outside the outer frame 3 contacts the conductive rod 9. The clamping ring 11 transmits electrical signals to the cable conductive block 10 through close contact with the conductor. When it is necessary to release the cable, the driving part drives the fixing rod 12 to move. The fixing rod 12 drives the folding end of the clamping ring 11 to slide along the groove wall of the clamping groove 4. The folding end will open the clamping groove 4 of the outer frame 3 to both sides, increasing the opening size of the clamping groove 4, thereby simultaneously releasing the cable and the conductor, realizing the separation of the cable and the cable fixing part.

[0039] When the fixing component moves to the waste discharge area, under the pressure of the tensioning shaft 18, the clamping groove 4 will undergo elastic deformation and its opening will expand. This allows the fixing rod 12 to pull the folding end of the clamping ring 11, causing the opening of the clamping ring 11 to expand synchronously. As a result, the clamping groove 4 will no longer clamp the cable, and the clamping ring 11 will no longer clamp the conductor inside the cable, allowing the cable to detach from the cable fixing part and the cable conductive part at the same time.

[0040] Example 3: The terminal fixing part includes a fixing platform 5 and multiple snap-fit ​​components. The fixing platform 5 is made of silicone rubber (which is elastic and insulating) and is fixedly installed on the conveyor belt 1 by adhesive bonding. The side of the fixing platform 5 has multiple sliding grooves evenly distributed along the circumference. Each sliding groove has a snap-fit ​​component slidably installed in it. The snap-fit ​​component includes a main rod 6 and a protrusion 7. The main rod 6 is made of plastic and the protrusion 7 is fixedly installed on the side facing the axis of the fixing platform 5 by injection molding. The protrusion 7 is made of rubber and has anti-slip texture on its surface. The protrusion 7 and the side wall of the terminal are interference fit. When installing the terminal, the operator places the terminal on the fixing platform 5. The side wall of the terminal will squeeze the protrusion 7, causing the protrusion 7 to deform and fit tightly against the side wall of the terminal, thereby fixing the terminal on the fixing platform 5 and preventing the terminal from shifting during the soldering process.

[0041] Terminal conductive block 8 is fixedly installed on the top of fixed platform 5 by embedding. One end of terminal conductive block 8 extends to the outside of fixed platform 5 and fits against the inner wall of terminal (to ensure electrical connection). The other end extends through the side of fixed platform 5 to the outside of fixed platform 5. The end of terminal conductive block 8 extending to the outside of fixed platform 5 is used to contact the corresponding conductive rod. When the fixed assembly moves with conveyor belt 1 between two conductive rods 9, the end of cable conductive block 10 extending to the outside of outer frame 3 contacts one of conductive rods 9, and the end of terminal conductive block 8 extending to the outside of fixed platform 5 contacts the other conductive rod 9. At this time, the continuity tester, conductive rod 9, cable conductive block 10, clamping ring 11, cable conductor, solder joint, terminal, and terminal conductive block 8 form a closed loop. The continuity tester can judge the welding quality by detecting the resistance value of the loop.

[0042] Example 4 The drive unit includes a connecting rod 13, which is slidably installed in a slide groove 14. The slide groove 14 is formed by cavities formed inside the outer frame 3, the support part, and the fixed platform 5. The connecting rod 13 is fixedly connected to the output rod of an electric push rod 15 installed inside the slide groove 14. One end of the connecting rod 13 is fixedly installed with a connecting frame 16 by welding. The open end of the connecting frame 16 is fixedly connected to the two folded ends of the clamping ring 11. The other end of the connecting rod 13 is fixedly installed with a connecting plate 17 by welding. The connecting plate 17 is slidably connected to the fixed platform 5 and fixedly connected to multiple main rods 6. When the detection group... When the product is deemed qualified, the piston rod of the electric push rod 15 retracts, driving the connecting rod 13 to slide along the slide groove 14. This allows the connecting frame 16 to pull the folding end of the clamping ring 11, causing the clamping ring 11 to open. Simultaneously, the connecting plate 17 pulls the main rod 6. When the folding end of the clamping ring 11 is pulled, it simultaneously opens the two side walls of the clamping groove 4, so that the clamping ring 11 and the clamping groove 4 no longer clamp the cable. When the connecting plate 17 pulls the main rod 6, the protrusion 7 passes over the terminal, thereby causing the snap-fit ​​to disengage from the terminal. At this time, under the action of gravity, the welded qualified cable and terminal fall off the fixing assembly.

[0043] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
