[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0037] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0038] Reference Figure 1-9 An infrared baking device for removing bubbles from the pressed sealant of inner and outer panels of a vehicle door according to the present embodiment is described.

[0039] like Figure 1 As shown, the device includes a side baking rack 1, which is divided into two groups and arranged in a left-right distribution, and the inner side forms a storage space for accommodating the vehicle shell. The vehicle shell moves in one direction on the slide, and stops moving when it moves to the storage space; the side baking rack 1 includes a support frame, and a heating lamp assembly is arranged on the support frame, and the heating end of the heating lamp assembly is arranged toward the storage space. The device also includes a profiling frame 4, and a plurality of heating lamps 9 are arranged on the profiling frame 4.

[0040] like Figure 2As shown, the heating lamp assembly includes a rear lamp box 13, a middle lamp box 14, and a front lamp box 15 which are sequentially arranged from one end of the support frame to the other end, and also includes a bottom lamp box 16 arranged below the support frame, and each lamp box is a heating lamp; the rear lamp box 13, the middle lamp box 14, the front lamp box 15, and the bottom lamp box 16 are connected to the support frame through a first universal connection hinge; and a plurality of heating lamps 9 are connected to the contour frame 4 through a second universal connection hinge. By setting the first universal connection hinge and the second universal connection hinge, the rear lamp box 13, the middle lamp box 14, the front lamp box 15, the bottom lamp box 16, and the plurality of heating lamps 9 can be adjusted in angle to ensure uniform heat, and by adjusting the angle, each lamp can be brought close to the sealant that needs to be baked.

[0041] The support frame includes a positioning frame 11 and an auxiliary support frame 12, and the connection ends of the rear light box 13, the middle light box 14, the front light box 15 and the bottom light box 16 are respectively fixed on the positioning frame 11 and the auxiliary support frame 12. The rear light box 13 irradiates toward the rear door sealant of the vehicle shell; the middle light box 14 irradiates toward the middle door sealant of the vehicle shell; the front light box 15 irradiates toward the front door sealant of the vehicle shell; and the bottom light box 16 irradiates toward the lower sealant of the vehicle shell.

[0042] like Figure 1 , 8 As shown in , 9, the profiling frame 4 is arranged at the front and rear ends of the accommodating space, and the profiling frame 4 is moved on the overhead rail 2 through the adjustment mechanism 3. After the vehicle shell enters into the accommodating space, the overhead rail 2 drives the profiling frame 4 to move to the front and rear ends of the vehicle shell; in one embodiment, the overhead rail 2 can be replaced by an electric hoist.

[0043] like Figure 8 and 9 As shown, the adjustment mechanism 3 includes a first electric telescopic rod 31 and a second electric telescopic rod 32 hinged between the moving end of the sky rail 2 and the profiling frame 4, and a linkage rod 34 is hinged on the output end of the first electric telescopic rod 31, and an adjustment electric telescopic rod 33 is arranged on the linkage rod 34, and the output end of the adjustment electric telescopic rod 33 is hinged with the profiling frame 4. The specific implementation method of the adjustment mechanism 3 is: after the sky rail 2 moves the profiling frame 4 to a predetermined position, the first electric telescopic rod 31 and the second electric telescopic rod 32 advance to push the profiling frame 4 to the front and rear end positions of the vehicle shell. At this time, the adjustment electric telescopic rod 33 is advanced or retracted to adjust the profiling frame 4 to a suitable position, so that each baking lamp 9 can be irradiated to a predetermined position. When the adjustment electric telescopic rod 33 is advanced, the hinge point of the first electric telescopic rod 31 and the profiling frame 4 is used as a fulcrum, and the second electric telescopic rod 32 cooperates with the retraction to achieve the tilt of the profiling frame 4, so that the baking lamp 9 can be irradiated on the vehicle shell.

[0044] In another embodiment, the auxiliary support frame 12 is provided with a lead structure, which can hide the heating lamp assembly on the support frame to avoid confusion of the lines. The lead structure includes a lead cavity provided in the auxiliary support frame 12 and a first opening groove 123 and a second opening groove 8 opened on the auxiliary support frame 12, and also includes a wiring groove 7 fixed on the auxiliary support frame 12; wherein the cable of the heating lamp assembly is introduced into the lead cavity through the first opening groove 123, and introduced into the wiring groove 7 through the second opening groove 8. The wiring groove 7 is used to centralize and store the cables, and then uniformly lead them out so that the cables will not be exposed to the outside and affect the work.

[0045] The auxiliary support frame 12 includes a base frame 121 and a buckle plate 122 detachably connected to the base frame 121. The buckle plate 122 is in a “┌” shape. The buckle plate 122 on the base frame 121 is specifically shaped like an angle steel. The buckle plate 122 and the base frame 121 are buckled together to form a lead cavity.

[0046] Since the heating lamp assembly can adjust the angle, each lamp box needs to turn to adjust the angle when adjusting the angle. At this time, the cable is pulled when turning. In order to prevent the fixed cable from being broken when turning, an elastic wire clamp 6 is arranged in the lead cavity. The elastic wire clamp 6 includes an upper spring sheet 63, a lower spring sheet 65, a bent spring sheet 64, a fixed sheet 62 and a clamping end 61. The upper spring sheet 63, the lower spring sheet 65 and the bent spring sheet 64 are connected as a whole, and a V shape is formed between the upper spring sheet 63 and the lower spring sheet 65.

[0047] The outer wall of the lower spring piece 65 is provided with a wing ear 66, which is rotatably connected to the base frame 121 through a hinge; the upper spring piece 63 is relatively arranged on the opposite side of the lower spring piece 65; the bent spring piece 64 is connected to one end of the upper spring piece 63 and the lower spring piece 65; the bent spring piece 64 is spring steel; the clamping end 61 is formed at the other end of the upper spring piece 63 and the lower spring piece 65; the cable is clamped and fixed on the clamping end 61, and the cable between the two clamping sections is in a bent and relaxed state. This part of the cable is a reserved section, which can meet the need to pull the cable when the light box is turned. During implementation, the light box turns to pull the cable, and the pulling force first acts on the clamping end 61 of the upper spring piece 63. Since the lower spring piece 65 is hinged and fixed, the V-shaped between the upper spring piece 63 and the lower spring piece 65 is stretched at this time, and its opening angle is pulled from a small angle to a large angle. When the cable is pulled, the reserved section of the cable is straightened to meet the turning work of the light box. When the lamp box returns to its original position, the bent spring piece 64 rebounds and resets, so that the V-shape between the upper spring piece 63 and the lower spring piece 65 is reset from a large angle to a small angle, and the reserved cable section is reset from a straightened state to a bent and relaxed state.

[0048] One end of the fixing plate 62 is bent and connected to the inner wall of the upper spring plate 63 and the lower spring plate 65, and a wire clamping cavity is formed between the fixing plate 62 and the upper spring plate 63 and the lower spring plate 65; the cable reserved section is attached to the inner wall of the upper spring plate 63 and the lower spring plate 65 and the bent spring plate 64 and is limited in the wire clamping cavity inside the fixing plate 62. The wire clamping end 61 includes a flat plate 69, and a wire clamping groove 67 is opened at the center of the flat plate 69. The flat plate 69 is opened with an open groove 68 that communicates with the wire clamping groove 67. The cable is introduced into the wire clamping groove 67 through the open groove 68, and the cable is clamped by the wire clamping groove 67.

[0049] A cable tie plate 5 fixed on the base frame 121 is provided in the lead-in cavity, one end of the cable tie plate 5 is fixed on the base frame 121; the cable tie plate 5 is provided close to the first opening groove 123; the cable tie plate 5 comprises a plate body, and a groove 51 is provided on the inner wall of the plate body. In order to ensure that the cable is bound in the lead-in cavity, the cable is introduced from the unfixed end into the groove 51 and is clamped and fixed by the plate body.

[0050] Working principle: The car body moves forward in one direction on the sled, and stops moving when it reaches the accommodation space. At this time, the rear light box 13, the middle light box 14, the front light box 15 and the bottom light box 16 illuminate the sealant on the side of the car body. The overhead rail 2 drives the profiling frame 4 to move to the front and rear ends of the car body; the first electric telescopic rod 31 and the second electric telescopic rod 32 advance to push the profiling frame 4 to the front and rear ends of the car body, and the electric telescopic rod 33 is adjusted to advance. With the hinge point of the first electric telescopic rod 31 and the profiling frame 4 as the fulcrum, the second electric telescopic rod 32 cooperates with the retraction work, and the profiling frame 4 tilts so that the baking lamp 9 can illuminate the sealant on the front and rear of the car body. The air in the sealant is expanded and then discharged.

[0051] The cables of each lamp box of the baking lamp assembly on the support frame are introduced into the lead-in cavity through the first opening groove 123, and are introduced into the wiring groove 7 through the second opening groove 8 for storage, and then uniformly led out so that the cables will not be exposed to the outside. When the lamp box turns, the cable is pulled, and the pulling force first acts on the clamping end 61 of the upper spring sheet 63. Since the lower spring sheet 65 is hinged and fixed, the V-shaped portion between the upper spring sheet 63 and the lower spring sheet 65 is stretched, and its opening angle is pulled from a small angle to a large angle. When the cable is pulled, the reserved section of the cable is straightened to meet the turning work of the lamp box. When the lamp box returns to its original position, the bent spring sheet 64 rebounds and resets, so that the V-shaped portion between the upper spring sheet 63 and the lower spring sheet 65 is reset from a large angle to a small angle, and the reserved section of the cable is reset from a straightened state to a bent and relaxed state. The elastic wire clamp 6 is used to prevent the cable from being pulled and causing the connection end to fall off when the lamp box turns.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
