Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration processing, in particular to a rotary hot stamping mechanism. Background Art

[0002] The left and right side trim panels of the luggage compartment are one of the necessary interior parts of an automobile. Since the functions carried by the automobile luggage compartment are increasing, the left and right sides of the luggage compartment also need to be equipped with more components according to functional requirements, such as in-vehicle 24V / 220V power supply, atmosphere lights, ventilation grilles, air purifiers, and temperature sensors, etc., to meet the increasingly broad usage requirements of customers.

[0003] The left and right side trim panels need to be assembled and fixed with the above-mentioned accessories through relevant process flows. In order to reduce the VOC odor of the whole vehicle, the assembly process generally adopts a hot stamping process. Currently, manufacturers often use manual hot stamping to process the left and right side trim panels. However, due to the large number of parts to be processed, during the manual hot stamping process, errors will occur in the hot stamping positions, and the working intensity of the processing personnel is relatively high, resulting in low production efficiency of the left and right side trim panels. Or in the prior art, the hot stamping module is installed on the slide rail of the production line, and the slide rail is distributed along the conveying direction of the production line and is hoisted above the production line. If the production line needs to be changed, the modification cost is relatively high. And if the production is changed, the position of the slide rail also needs to be changed, but this will result in a large number of components involved in the hot stamping process and relatively large occupation of the factory area space. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rotary hot stamping mechanism to solve the problem that the components involved in the hot stamping process in the prior art occupy a large amount of space.

[0005] To achieve the above object, the utility model adopts the following technical solutions: The utility model provides a rotary hot stamping mechanism, which includes a fixed frame. A rotating shaft is vertically installed on the fixed frame. A gear is installed at the lower end of the rotating shaft. A flat push cylinder is also installed on the fixed frame. The flat push cylinder pushes a first connecting rod inside to move. A rack is installed at the front end of the first connecting rod. The rack meshes with the gear. A follower frame is installed at the upper end of the rotating shaft. A hot stamping module is installed on the follower frame. The hot stamping module includes a lifting cylinder, a hot stamping frame, and a hot stamping head. The hot stamping head is installed on the hot stamping frame. The lifting cylinder internally pushes a second connecting rod to move. The second connecting rod is connected to the hot stamping frame. A guide rail is installed on the follower frame. The hot stamping frame slides along the guide rail.

[0006] Preferably, two groups of lifting cylinders are fixed on the follower frame, and the lifting cylinders correspond to the hot stamping frames one by one.

[0007] Preferably, the hot ironing rack is L-shaped. The hot ironing rack includes a first side plate and a second side plate. Five groups of hot ironing heads are vertically installed on the first side plate. The side surface of the second side plate is connected to the second connecting rod, and the back surface of the second side plate is slidably installed on the guide rail.

[0008] Preferably, a blowing pipe is vertically installed on the first side plate, and the end of the blowing pipe faces the hot ironing head.

[0009] Preferably, rollers are installed on the side surface of the rotating shaft. The axis of the rollers is perpendicular to the rotating shaft. A stop block is installed on the lower side of the fixed frame. An inclined surface is formed on the lower side of the stop block. The inclined surface forms an acute angle with the horizontal plane, and the rollers are in contact with the inclined surface.

[0010] Preferably, the fixed frame is rectangular. Fixing screw holes are opened on the bottom surface of the top of the fixed frame. The fixing screw holes are installed circumferentially on the rotating shaft, and bolts pass through the fixing screw holes and are screwed into the stop block.

[0011] Preferably, a limiting hole is opened on the rotating shaft, and a plugging cylinder is installed on the fixed frame. The plugging cylinder pushes a plugging rod to be plugged into the limiting hole.

[0012] Beneficial effects: The rack on the first connecting rod is driven to move by the flat push cylinder, so that the gear rotates. After the follower frame rotates to the specified position, the lifting cylinder pushes the second connecting rod to move, so that the hot ironing head on the hot ironing rack contacts the interior trim panel for hot ironing. The rotation position of the hot ironing rack is controlled by the extended length of the flat push cylinder. This rotary hot ironing mechanism is placed on one side of the production line, the slide rail on the upper side of the production line is cancelled, the floor area required by the hot ironing mechanism is reduced, and the rotary hot ironing mechanism can be placed flexibly. When the production is changed, it is more convenient to only move the position of the rotary hot ironing mechanism. Description of the Drawings

Detailed Embodiments

[0015] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0016] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0017] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above the top of", and "on the top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is lower than that of the second feature.

[0018] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0019] Under the prior art, by hoisting the slide rail to the top of the factory area and installing the hot iron head on the slide rail, when the production line is updated and replaced, it is necessary to change the slide rail together, resulting in a relatively high modification cost and time consumption.

[0020] To solve the above problems, as Figure 1 shown, the present utility model provides a rotary hot iron mechanism, which includes a fixed frame 1. A rotating shaft 2 is vertically installed on the fixed frame 1. A gear 3 is installed at the lower end of the rotating shaft 2. A flat push cylinder 4 is also installed on the fixed frame 1. The flat push cylinder 4 pushes the first connecting rod inside to move. A rack 5 is installed at the front end of the first connecting rod. The rack 5 meshes with the gear 3. A follower frame 6 is installed at the upper end of the rotating shaft 2. A hot iron module is installed on the follower frame 6. The hot iron module includes a lifting cylinder 7, a hot iron frame 8, and a hot iron head 9. The hot iron head 9 is installed on the hot iron frame 8. The lifting cylinder 7 pushes the second connecting rod inside to move. The second connecting rod is connected to the hot iron frame 8. A guide rail 10 is installed on the follower frame 6. The hot iron frame 8 slides along the guide rail 10.

[0021] Place the rotary hot stamping mechanism on one side of the production line. Then, when hot stamping the interior trim panel is required, the push cylinder 4 extends, the rack 5 moves along its own length direction, the rack 5 drives the rotating shaft 2 to rotate. Then, a follower frame 6 is installed on the rotating shaft 2, and the follower frame 6 rotates the hot stamping module to the upper side of the trim panel. Then, the lifting cylinder 7 is activated to push the second connecting rod to convey the hot stamping frame 8 downward, making the hot stamping head 9 contact the trim panel to achieve the hot stamping process. Since the rotary hot stamping mechanism is only set on one side of the production line, when the production line changes, only need to move the rotary hot stamping mechanism to adjust along with the production line. At the same time, adjust the position of the hot stamping head 9 through the push cylinder 4 and the lifting cylinder 7. Compared with manual adjustment, it is more accurate and can save labor and reduce labor costs.

[0022] Two groups of lifting cylinders 7 are fixed on the follower frame 6, and the lifting cylinders 7 correspond to the hot stamping frames 8 one by one. In order to adapt to the diversified processing methods of the current trunk trim panels, two groups of lifting cylinders 7 are installed on a single follower frame 6. Among them, the two groups of lifting cylinders 7 can drive their respective hot stamping frames 8 to move, and perform the hot stamping process on the areas at different height positions of the trim panel, making the processing method more diversified and capable of adapting to the production of different models of vehicles.

[0023] The hot stamping frame 8 is L-shaped. The hot stamping frame 8 includes a first side plate 81 and a second side plate 82. Five groups of hot stamping heads 9 are vertically installed on the first side plate 81. The side of the second side plate 82 is connected to the second connecting rod, and the back of the second side plate 82 is slidably installed on the guide rail 10. The five groups of hot stamping heads 9 among them can perform the hot stamping process on different positions of the trim panel. At the same time, the hot stamping heads 9 can be replaced by removing nuts, and then replace different numbers of hot stamping heads 9 and install the hot stamping heads 9 in different positions, so that the hot stamping module of the present utility model can adapt to the production of different models of interior trim panels.

[0024] An air blowing pipe 20 is vertically installed on the first side plate 81. The end of the air blowing pipe 20 faces the hot stamping head 9. An air blowing pipe 20 is correspondingly installed on each group of hot stamping heads 9. Through the air blowing pipe 20, the position where the hot stamping head 9 performs hot stamping can be cooled.

[0025] A roller 40 is installed on the side of the rotating shaft 2. The axis of the roller 40 is perpendicular to the rotating shaft 2. A stop block 30 is installed under the fixed frame 1. An inclined surface 301 is formed under the stop block 30. The inclined surface 301 forms an acute angle with the horizontal plane. The roller 40 abuts against the inclined surface 301.

[0026] When the roller 40 contacts the inclined surface 301 on the stop block 30, the rotation of the rotating shaft 2 is stopped. The push cylinder 4 continues to extend, and the roller 40 is pressed against the inclined surface 301 to limit the rotating shaft 2, so that the hot stamping head 9 can accurately dock at a fixed position, improving the processing accuracy.

[0027] The fixing bracket 1 is rectangular. Fixing screw holes are provided on the bottom surface of the top of the fixing bracket 1. The fixing screw holes are installed circumferentially on the rotating shaft 2, and bolts pass through the fixing screw holes and are screwed into the stopper 30. The position of the limiting block can be flexibly adjusted on the fixing bracket 1, so that after the rotating shaft 2 reaches the specified position, the rotating shaft 2 stops rotating and reaches the specified position through the pressing connection of the roller 40 and the inclined surface 301.

[0028] The present utility model can also limit the rotation shaft 2 in other forms. A limiting hole is provided on the rotation shaft 2, and a plug cylinder is installed on the fixing bracket 1. The plug cylinder pushes the plug rod to be inserted into the limiting hole. When the rotation shaft 2 rotates to a specified angle, the plug rod in the plug cylinder extends out, so that the rotation shaft 2 stops moving, limits the rotation shaft 2, and makes the processing accuracy of the hot iron 9 higher.

[0029] Obviously, the above-mentioned embodiments of the present utility model are only examples for clearly explaining the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
