Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, and in particular to an elastic support welding device. Background Art

[0002] At present, the circuit boards in automobiles are directly installed in the main controller. Not only is the installation strength not high, but this type of automobile circuit board is generally installed in a close-fitting manner, and the overall heat dissipation is poor. In addition, when the automobile circuit board is installed, the screws are directly inserted into the automobile circuit board for fixing. When encountering external vibrations (such as car bumps), automobile circuit boards in this way are easily damaged due to hard fixing.

[0003] For this purpose, the applicant has designed an elastic support member (such as Figure 1 As shown in the figure), the circuit board can be supported to improve the heat dissipation at the bottom, and it can also play the role of elastic support when the car is bumpy. Since the elastic support needs to be laser welded to weld the two sets of metal sheets to form the lower support surface after bending, it is necessary to ensure that the ends of the two sets of metal sheets are completely overlapped during welding without misalignment. During the previous processing, the metal sheets on both sides are in a free state and in most cases do not completely overlap, so a specific welding device is required for positioning welding.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] The present invention discloses an elastic support member welding device, which realizes continuous welding processing of the elastic support member. To realize continuous processing, the elastic support member is transmitted in the form of a material belt 1. The specific material belt structure is as follows: Figure 2 As shown, it includes a middle connecting portion 11 and pressure edges 12 on both sides, and elastic support members 13 spaced between the connecting portion and the pressure edges. At the same time, in order to improve the precise positioning during welding, positioning holes 14 are also spaced apart on the pressure edges. This bilaterally symmetrical material strip structure can realize simultaneous processing on both sides, thereby improving efficiency. At the same time, the symmetrical structure also ensures stability during the transmission process and will not tilt sideways.

[0029] The present invention discloses an elastic support welding device, the structure of which is as follows: Figure 3 As shown, it includes a cabinet 2, a loading component 3 installed on the cabinet in sequence, a first pulling component 4, a welding component 5, a CCD detection component 6, a defective product cutting component 7, a second pulling component 8 and a cutting component 9. At the same time, in order to realize the bearing of the material belt during transmission, a material belt bracket 10 is also provided between the loading component and the welding component, between the welding component and the defective product cutting component, and between the defective product cutting component and the cutting component. The material belt bracket can realize the bearing of the material belt during the pulling process. The material belt is fed into the material belt bracket through the loading component, and is fed into the welding component for positioning welding through the first pulling component, and then the welding quality is detected by the CCD detection component. The unqualified support parts are cut by the defective product cutting component, and then they are cut and discharged according to the specified length by feeding them into the cutting component.

[0030] Specifically, the feeding assembly structure is as follows: Figure 4As shown, it includes a loading rail 31 and a pressing roller 32. The loading rail is fixed on the cabinet through a first bracket 33. The surface of the loading rail has a U-shaped rail groove. At the same time, pressure plates 34 are provided on both sides, and there is a certain gap between the pressure plate and the surface of the loading rail. The elastic support on the material belt is located in the rail groove, and the pressure edges on both sides are located between the pressure plate and the loading rail. The two ends of the pressing roller are fixed to the loading rail with roller brackets 35. The two ends of the pressing roller are connected to the roller brackets with elastic pins 36, that is to say, the pressing roller can move up and down and has a certain downward pressure. When used, the pressing roller presses the middle part of the material belt from above to avoid deformation caused by arching in the middle during the transmission of the material belt. At the same time, in order to ensure the smooth entry of the material belt, the end of the loading rail is connected with an arc-shaped material guide groove 37.

[0031] The first material pulling component has the same structure as the second material pulling component, and both are used to realize the function of moving the material. Figure 5 As shown, it includes a linear module 41, a mounting frame 42, an upper clamping plate 43, a lower clamping plate 44, a first cylinder 45 and a second cylinder 46. The mounting frame is fixed to the slider of the linear module, the lower clamping plate cooperates with the first cylinder to be fixed to the mounting frame, the upper clamping plate cooperates with the second cylinder to be fixed to the mounting frame, and the upper clamping plate and the lower clamping plate are arranged opposite to each other to achieve clamping of the material strip. The upper clamping plate and the lower clamping plate are both U-shaped, and when they are matched, a square groove is formed for the material strip bracket to pass through. The first cylinder and the second cylinder are controlled to achieve clamping of the pressure edges on both sides of the material strip, and after clamping, the linear module is used to perform transverse movement to achieve material pulling.

[0032] The material belt bracket supports the material belt, and its structure is as follows: Figure 6 As shown, it includes a support plate 101 and a cover plate 102, wherein the support plate is a long strip structure, and its two ends are fixed to adjacent components by matching mounting seats, and the cover plate is an I-shaped structure, and its two ends are also fixed to adjacent components, and there is a gap between the cover plate and the support plate that is greater than the thickness of the material strip. When in use, the connecting part of the material strip is placed on the support plate, and the elastic support members and the pressing edge on both sides are suspended, and the cover plate is synchronously located above the connecting part, which plays a role of upper limit during transportation, and the material strip bracket passes through the square slot formed by the upper clamp and the lower clamp, and the suspended pressing edge is located between the upper and lower clamps to achieve clamping.

[0033] The welding assembly realizes the restoration of the misalignment of the elastic support member and performs welding, and its structure is as follows: Figure 7-8As shown, it includes a mounting plate 51, a lifting and positioning assembly 52 fixed in the middle of the mounting plate for lifting and positioning, a material pressing assembly 53 fixed on the mounting plate and located on both sides of the lifting and positioning assembly, a conveying track 54 fixed on the lifting and positioning assembly for carrying the material belt, and a laser welding assembly (not shown) located below the mounting plate for laser welding the elastic support member. The material belt 1 moves in the conveying track, and the lifting and positioning assembly is lifted and lowered to return and position the elastic support member welding device. At the same time, the material pressing assembly presses the elastic support member welding device from above, and then the laser welding assembly is used to weld from below.

[0034] The lifting and positioning assembly includes a support seat 521, a lifting plate 523 installed above the support seat in cooperation with a lifting cylinder 522, and a plurality of positioning blocks 524 fixed on the lifting plate. A slot is provided on the upper surface of the support seat, and the lifting plate is located above the slot of the support seat, and is slidably assembled with the guide column and guide sleeve structure and the upper surface of the support seat. At the same time, the back sides of both ends are fixed to the telescopic ends of the lifting cylinder, and the other end of the lifting cylinder is fixed to the mounting plate, so that the lifting plate can be lifted and lowered under the control of the lifting cylinder. The positions of the plurality of positioning blocks on the lifting plate correspond one by one to the positions of the plurality of elastic support members on the material strip, so as to realize synchronous positioning welding of a plurality of elastic support members at a time. At the same time, a plurality of positioning pins are also provided on the surface of the lifting plate. As the lifting plate rises, the positioning pins are first inserted into the positioning holes of the material strip to limit the front and rear positions of the material strip to ensure that the elastic support part can be accurately positioned when the positioning blocks are lifted.

[0035] The positioning block is provided with a positioning groove 525, and a through hole is provided at the bottom of the positioning groove. The laser welding assembly located below performs laser welding on the elastic support member welding device in the positioning groove through the hole. The notch of the positioning groove is a flared structure 526, which is convenient for inserting the lower end of the elastic support member welding device. By controlling the size of the positioning groove to be consistent with the size after the lower end of the elastic support member welding device is completely overlapped, as the positioning groove is lifted, the lower end of the elastic support member welding device enters the flared opening, and as it continues to enter, the two groups of misaligned metal springs return to their original positions and meet the standards, and then laser welding is performed.

[0036] The press assembly structure includes a press support seat 531, a press block mounting seat 532, and multiple groups of press blocks 533. The lower end of the press block support seat is fixed on the surface of the mounting plate, and the upper end is an inclined surface, and the side close to the lifting and positioning assembly is lower. The press block mounting seat is L-shaped, and the bottom of its transverse surface cooperates with the slide rail 534 to be fixed on the inclined upper end surface of the press block support seat, and is connected to the cylinder 535 fixed on the pressure support seat. Multiple groups of press blocks are installed at intervals on the vertical surface of the press block mounting seat, and the spacing distance between multiple press blocks is the same as the spacing distance between two adjacent elastic support welding devices on the material strip.

[0037] The cylinder controls the pressure block mounting seat to move forward and backward along the slide rail. Since the upper surface of the pressure support seat is a sloped structure, the pressure block mounting seat moves obliquely downward, and the pressure block moves forward and downward synchronously. In order to ensure that the pressure stroke is adjustable, the upper end of the pressure block cooperates with the elastic pin 536 and the mounting strip 537 on the side of the pressure block mounting seat. At the same time, the pressure block and the side of the pressure block mounting seat are slidably installed through the slide rail 538, so that the pressure block can only move up and down and will not shift left and right, thereby ensuring the stability of the pressure.

[0038] The conveying track structure is similar to the material belt bracket structure, and their functions are both to realize the movement of the material belt inside, while the elastic support members on both sides are suspended in the air, and the specific structure will not be described in detail.

[0039] The CCD detection component includes a first CCD camera 61 and a second CCD camera 62 that are relatively arranged. At the same time, in order to enhance the clarity of the detection, a ring light source 63 is also provided in front of the CCD camera. The light source provides brightness. The first CCD camera and the second CCD camera respectively obtain images of the elastic support members on both sides of the material strip to analyze the welding quality. For welding quality that is unqualified, the feedback control module controls the unqualified product cutting component to cut the corresponding product.

[0040] The structure of the defective product cutting component is as follows Fig. 9 As shown, it includes a base 71, a cutting seat 72 arranged on the base, a cutting cylinder 74 fixed on the base by a bracket 73, and a cutting knife 75 arranged at the telescopic end of the cutting cylinder. The upper surface of the cutting seat is provided with a U-shaped groove for the feeding belt to pass through. The cutting knife is located directly above the cutting seat. When cutting is required, the cutting cylinder controls its descent to cut out unqualified parts from the material belt. A blanking port is provided below the cutting seat, and a blanking trough 76 is provided at the blanking port. The cut unqualified products are discharged from the blanking trough. In the field of automation, cutting is a conventional structure, so the specific structure of the cutting knife is not described in detail here, and the existing structure can be referred to.

[0041] The cutting assembly cuts the material strip so that the length of the material strip after cutting is consistent to meet the subsequent processing requirements. The specific structure is as follows Fig.10 As shown, it includes a mounting column 91, a cutting cylinder 92 fixed above the mounting column, a cutter 93 provided at the telescopic end of the cutting cylinder, a lifting cylinder 94 fixed below the mounting column, and a cutting bracket 95 provided at the telescopic end of the lifting cylinder. During the cutting operation, the cutting bracket is lifted by the lifting cylinder to support the material strip area between the two elastic support members from below, and at the same time, the cutting cylinder controls the cutter to descend to cut the material strip. A lower hopper 96 is provided at the end of the cutting assembly for collecting the cut material strip.

[0042] The elastic support welding device disclosed in the present invention mainly realizes the return of the dislocated part of the elastic support, and a series of automated operations such as synchronous welding, detection, and unloading. The entire structure is simple and reasonable, and can effectively replace manual operation, ensuring welding quality while improving processing efficiency.
