Description

Technical Field

[0001] This invention relates to the technical field of automotive parts, specifically a hot riveting and welding machine for automotive door panels. Background Technology

[0002] Hot riveting welding machines are used to connect parts made of different materials, enabling thermosetting plastics to connect with thermoplastic parts, or plastic parts to connect with metal. They utilize pre-existing plastic rivets, ribs, and vertical ribs on the molded parts, which are then pressed through pre-drilled holes in the stamped metal sheet structure. The protruding parts of the rivets (hot studs) on the metal surface are softened by controlled heat melting and then pressed, cooled, and reshaped by a special metal forming rivet head and clamped. Using rivet heads of specific shapes, countersunk riveting, hemispherical riveting, arc-flange riveting, and edge-folding inlay wrapping of plastic rivets can be achieved.

[0003] In the automotive assembly field, door panel assembly involves numerous components with overlapping and interlocking connections. Therefore, the welding of door panel components to the assembly represents a highly integrated process in the automotive industry. The assembly of these components is often accomplished through methods such as hot riveting and welding.

[0004] However, most existing automotive door panel hot riveting welding machines rely on manual loading and unloading, which leads to high worker fatigue and can even cause burns if not operated properly. The machines are also inefficient. Furthermore, when cooling the plastic parts after hot riveting, air is usually used for cooling, which fails to achieve the desired pressing and shaping effect, resulting in loose welds on the finished product.

[0005] Therefore, it is necessary to provide a hot riveting and welding machine for automotive door panels that can achieve automated processing. Summary of the Invention

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0038] Please see Figure 1-4 The present invention provides a technical solution: a hot riveting and welding machine for automotive door panels, comprising a stacking section 2, a moving seat 1, a processing section 3, an unloading section 4, and a receiving section 5; wherein,

[0039] The stacking section 2 is used to stack several door panel bodies 6 to be processed in sequence, and a movable support platform 201 is provided at the lower end of the stacking section 2.

[0040] The movable seat 1 is used to carry a single door panel body 6 for movement. The movable seat 1 includes a contour seat 101 and a pusher. The contour seat 101 pushes the support table 201 to move and screens out the single door panel body 6 and transmits it. The pusher is used to push the door panel body 6 out of the contour seat 101.

[0041] The processing unit 3 includes a driving component, a hot riveting assembly 301 and a cold mold assembly 302. The hot riveting assembly 301 is used to perform hot riveting welding on the door panel body 6 on the contour base 101. The cold mold assembly 302 is used to cool and shape the welded door panel body 6. The driving component is used to drive the hot riveting assembly 301 and the cold mold assembly 302 separately.

[0042] The unloading section 4 includes a wedge base 401 and several unloading rods 402. The wedge base 401 is used to push the pusher, and the unloading rods 402 are used to separate the door panel body 6 on the pusher.

[0043] The receiving section 5 is used to receive the door panel body 6 on the unloading rod 402.

[0044] Specifically, firstly, workers sequentially place the door panel bodies 6 to be processed into the stacking section 2, with the support platform 201 providing support from below. When the contouring seat 101 moves, it first moves towards the support platform 201, pushing the support platform 201 out of the lower end of the stacking section 2. The contouring seat 101 then moves to the lower side of the stacking section 2, causing each door panel body 6 to fall into the contouring seat 101 under gravity. The contouring seat 101 then moves towards the processing section 3, where the individual door panels are separated under the constraint of the stacking section 2, achieving automatic feeding. Next, the driving component individually drives the hot riveting assembly 301 to descend for hot riveting welding. Afterward, the contouring seat 101 moves to the cold mold assembly 302, and the driving component then individually... The cold mold assembly 302 descends to press and cool the door panel body 6 after hot riveting, resulting in good molding effect. By using a single drive component, the hot riveting assembly 301 and the cold mold assembly 302 are driven separately, saving costs. Then, the contouring seat 101 moves to the upper side of the wedge base 401. The pusher pushes the door panel body 6 away from the contouring seat 101 by contacting the wedge base 401. Next, the unloading rod 402 passes between the contouring seat 101 and the door panel body 6 and contacts the door panel body 6. As the contouring seat 101 moves away from the wedge base 401, the pusher descends, while the door panel body 6 remains on the unloading rod 402 and finally falls into the receiving part 5, completing the automatic receiving without manual intervention. It has a high degree of automation and high production efficiency.

[0045] The contour base 101 has two guide rods 102 inside, which pass through both ends of the contour base 101 and slide with it. The lower end of the contour base 101 is provided with a drive wheel 103 and two driven wheels 104. The pusher includes two pusher plates 106 and four pusher rods 107. The lower end of the pusher rod 107 is connected to the driven wheels 104. The pusher plate 106 is recessed into the groove of the corresponding shape opened at the lower end of the contour base 101. The pusher rod 107 passes through the bottom end of the contour base 101 and slides with it. The pusher rod 107 is connected to the pusher plate 106.

[0046] A baffle plate 108 is fixedly connected to the push rod 107, and a spring 109 is provided on the outer side of the push rod 107. The two ends of the spring 109 are respectively connected to the lower end of the contour seat 101 and the baffle plate 108.

[0047] Specifically, the moving contour base 101 is guided by two guide rods 102 to ensure its directional movement. The movement of the contour base 101 can be driven by controlling the power wheel 103 at its bottom. When the driven wheel 104 moves onto the wedge base 401, the driven wheel 104 rolls upward along the inclined surface of the wedge base 401, thereby pushing the upper push rod 107 and the push plate 106 inside the contour base 101 to move upward, thereby pushing the door panel body 6 located inside the contour base 101 upward for easy unloading.

[0048] Spring 109 is provided to facilitate the reset of driven wheel 104 when it comes off the wedge base 401, and to allow push plate 106 to be completely sunk into the groove in contour base 101, making it easier to insert the next door panel body 6.

[0049] The processing unit 3 includes a cylinder 306, with a top plate 7 fixedly connected to the upper end of the cylinder 306. A connecting plate 307 is driven to move on the upper side of the cylinder 306. An electromagnet 308 and an electromagnet 309 are respectively provided at both ends of the connecting plate 307. A magnetic rod 310 is provided through the inner side of the electromagnet 308, and a magnetic rod 311 is provided through the inner side of the electromagnet 309. The magnetic rods slide with the electromagnets and pass through the top plate 7 with a clearance fit. The lower end of the magnetic rod 310 is connected to the hot riveting assembly 301, and the lower end of the magnetic rod 311 is connected to the cold mold assembly 302.

[0050] Specifically, when hot riveting welding is required, cylinder 306 retracts, pulling connecting plate 307 down. Connecting plate 307 drives two electromagnets to move. At this time, by energizing only electromagnet 308, it generates attraction, attracting and fixing magnetic rod 310, thereby driving magnetic rod 310 down. This allows hot riveting assembly 301 to perform hot riveting welding on the rivet post on the door panel body 6. After welding is completed, cylinder 306 drives hot riveting assembly 301, magnetic rod 310, and electromagnets back to their original positions. Then... The door panel body 6, after hot riveting, is moved to the lower end of the cold mold assembly 302 by the contour seat 101. Similarly, only the electromagnet 309 is energized, and the cylinder 306 drives it, causing the cold mold assembly 302 to descend and press, cool, and reshape the riveted joint after hot riveting. Unlike other cooling methods such as blowing air, this technical solution uses press-forming cooling to make the structure of the riveted joint fit tightly, resulting in good welding effect and good forming quality. Moreover, only one cylinder 306 is used as the driving source, saving equipment costs.

[0051] The hot riveting assembly 301 includes several sets of hot melt welding heads and a lifting plate 304. The cold mold assembly 302 includes several sets of cooling mold heads and a lifting plate 305. A spring 314 is provided on the outside of the magnetic rod. The two ends of the spring 314 are connected to the top plate 7 and the lifting plate, respectively.

[0052] Specifically, the number and position of the hot melt welding head and the cooling mold head need to be set accordingly, so that the cooling mold head can press and cool each weld point to form a shape. Then, spring 4 314 is set to connect the lifting plate and the top plate 7, so that any one of the lifting plates can be kept at a certain height without being driven and will not fall. This makes it convenient for the cylinder 306 to move only one component while the other component remains stationary.

[0053] The shape of the cooling die head can be set to the required riveting shape, making it highly versatile.

[0054] Positioning posts 303 are provided at both ends of the lifting plate. Several sets of positioning slots 105 are provided on the upper side of the contour base 101. The positioning slots 105 are correspondingly provided with the positioning posts 303. The positioning posts 303 pass through the lifting plate and slide with it. The positioning posts 303 also pass through the top plate 7 and slide with it. A circular piece 313 is fixedly connected to the outside of the positioning posts 303. A spring 312 is provided on the outside of the positioning posts 303. The two ends of the spring 312 are respectively connected to the lifting plate and the circular piece 313. The lowest end of the positioning post 303 is lower than the lowest end of the hot melt welding head and the cooling mold head.

[0055] Specifically, since the contouring seat 101 drives the door panel body 6 to move and process, it is necessary to ensure the accuracy of the processing positioning. When the lifting plate descends, under the thrust of the spring 312, the positioning pin 303 first inserts into the positioning groove 105 on the contouring seat 101 to further position the contouring seat 101 and the lifting plate, which is convenient for aligning the welding and cooling positions. Afterwards, the lifting plate continues to descend, and the spring 312 is compressed until the hot melt welding head or cooling mold head contacts the door panel body 6. Since the upper side of the positioning pin 303 penetrates the top plate 7 and the lower end is inserted into the positioning groove 105, the vertical accuracy of the positioning pin 303 is ensured, which facilitates the sliding of the positioning pin 303 with the lifting plate when it moves up and down, and provides guidance. The movement accuracy is high.

[0056] The stacking section 2 includes several sets of guide members 202, which guide the stacked door panel bodies 6 as they fall. A support platform 201 supports the stacked door panel bodies 6. A left side plate 203 is fixedly connected to one side of each guide member 202. A guide rod 102 passes through the support platform 201 and slides with it. The support platform 201 passes through the left side plate 203 and slides with it. Several limiting plates 206 are fixedly connected to the outer end of the support platform 201. A baffle 204 is fixedly connected to one end of the guide rod 102. A spring 205 is provided on the outer side of the guide rod 102. Both ends of the spring 205 are connected to the baffle 204 and the support platform 201, respectively. The distance between the guide member 202 and the support platform 201 is less than the height of a single door panel body 6.

[0057] Specifically, several guide members 202 are used to initially guide the stacked door panel bodies 6, and the support platform 201 is also guided by the guide rod 102, so that the contouring seat 101 pushes the support platform 201 to move along the guide rod 102, and the upper door panel body 6 contacts the surface of the contouring seat 101 until it falls into the corresponding shaped cavity of the contouring seat 101, completing the automatic feeding. At this time, the contouring seat 101 returns to its original position, and the support platform 201, under the reset action of the second spring 205, adheres to the contouring seat 101 and moves at the same time, and is supported again at the lower end of the several door panel bodies 6. A limiting plate 206 is set to prevent the second spring 205 from pushing it away from the lower end of the stacking part 2, completing the separation of individual door panels. No manual intervention is required, and the degree of automation is high.

[0058] The upper side of the support platform 201 is provided with several sets of rolling wheels, and the end of the support platform 201 near the contour base 101 is provided with a chamfer.

[0059] Specifically, by setting several sets of rollers, the friction of the support platform 201 on the upper door panel body 6 can be reduced when the support platform 201 moves, thus avoiding wear. Roller can also be set at some positions of the contour base 101, which is more practical. Furthermore, by setting a chamfer at one end of the support platform 201, the damage to the door panel body 6 when the support platform 201 is reset can be further reduced, preventing jamming and increasing the fault tolerance rate.

[0060] One end of the guide rod 102 is fixedly connected to the right side plate 8. The wedge base 401 is fixed to the bottom of the right side plate 8. The wedge base 401 is set as a right-angled trapezoid. The unloading rod 402 passes through the right side plate 8 and is slidably engaged with it. A motor 403 is fixedly connected to the inside of the right side plate 8. A threaded rod 404 is provided on one side of the motor 403. Several unloading rods 402 are connected to each other through a moving plate 405. The threaded rod 404 passes through the moving plate 405 and is threadedly connected to it.

[0061] Specifically, when the driven wheel 104 rolls upward along the inclined surface of the wedge base 401, it pushes the upper push rod 107 and the push plate 106 in the contour seat 101 to move upward, thereby pushing the door panel body 6 located in the contour seat 101 upward. At this time, the motor 403 drives the threaded rod 404 to rotate. The threaded rod 404 is threadedly connected to the moving plate 405. Under the guidance of the two unloading rods 402, the unloading rods 402 move and pass through the lower side of the door panel body 6. As the driven wheel 104 leaves the wedge base 401, the push rod 107 descends, while the door panel body 6 remains on the unloading rod 402, completing the automatic unloading function.

[0062] One end of the wedge base 401 extends to the outer side of the right side plate 8. Several transmission rollers 408 are provided on the upper side of the wedge base 401. The transmission rollers 408 are driven to rotate by a motor assembly. A receiving box 406 is provided on the upper side of the transmission rollers 408. Several limiting plates 407 are fixedly connected to both ends of the receiving box 406. The receiving box 406 passes through the right side plate 8 and slides with it.

[0063] Specifically, the length of the transmission roller 408 is less than the distance between the two driven wheels 104 to avoid contact between the two driven wheels 104 and the transmission roller 408. After unloading, the transmission roller 408 rotates, driving the receiving box 406 to move through the right side plate 8 to the lower side of the door panel body 6. Then, the control motor 403 reverses, causing the unloading rod 402 to retract, while the upper door panel body 6 is blocked by the right side plate 8. Until the unloading rod 402 is completely retracted, the door panel body 6 falls into the receiving box 406 at the lower end. Then, the transmission roller 408 reverses, moving the door panel body 6 to the outside of the right side plate 8 to avoid blocking the next movement of the driven wheels 104 to the wedge base 401, and also to facilitate the workers to pick up the material.
