Description

Technical Field

[0001] The invention relates to a UV irradiation device, in particular to a UV irradiation device for a concave surface of a special-shaped through-type vehicle lamp cover. Background Art

[0002] As more and more cars adopt through-type headlights that run horizontally from left to right, the output of through-type headlights has increased year by year. Compared with the left and right independent split headlights, the lampshade of the through-type headlight is longer and the processing technology is more complicated. The concave surface (i.e., the inner surface) of the existing lampshade needs to be sprayed with a coating to prevent the inner surface from fogging. After spraying, it is necessary to use a UV lamp to evenly irradiate it so that the coating hardens and firmly adheres to the inner surface of the lampshade. Since the lampshade of the through-type headlight is concavely curved along the axial direction as a whole and its cross-section is concave, in order to evenly illuminate its concave surface, it is necessary to design a light strip that matches the shape of the lampshade to illuminate it. However, the length, width and curvature of the curved parts on both sides of each car headlight are different. It is difficult to match the lampshades of various types of headlights with one light strip; if a light strip is developed separately for each type of headlight, it will bring higher costs. At the same time, the through-type headlights of many cars are wide on both sides and narrow in the middle, such as Figure 1 As shown, the special-shaped through-type lampshade 1 includes large housings 101 on both sides and a small housing 102 in the middle. The large housing 101 is used to install various lamps such as the width indicator lamp, brake lamp or high and low beam lamps at the front of the vehicle, and the small housing 102 is generally used to install a slender light strip. Such a special-shaped through-type lampshade with different axial widths cannot be evenly illuminated by existing illumination devices. Summary of the invention

[0003] The present invention provides a UV irradiation device for concave surfaces of special-shaped through-type vehicle lamp covers, which can utilize a plurality of cylindrical irradiation lamps with adjustable spacing to uniformly irradiate concave surfaces of special-shaped through-type vehicle lamp covers with different axial widths, thereby improving the curing speed of the coating and the hardness after curing.

The longitudinal beam is arranged along the radial direction of the conveyor belt, and a tray is slidably matched with the lower side of the longitudinal beam along its axial direction.

A swing shaft parallel to the conveyor belt is connected to the lower side of the turntable, and a swing sleeve rotating around its axis is provided on the outer side of the swing shaft, and one side of the swing sleeve is connected to the irradiator.

[0007] The irradiator includes a pair of support beams parallel to the conveyor belt, one end of the support beam is connected to the swing sleeve, and the other end is connected to the two ends of the middle swing pin; the pair of support beams are slidably matched with a limit sleeve, and a swing pin is respectively provided at both ends of the limit sleeve, and each swing pin is sequentially sleeved with an inner swing rod and an outer swing rod; one end of each inner swing rod is hinged to the swing pin, and the other end is hinged to the end of the inner swing pin; one end of each outer swing rod is hinged to the swing pin, and the other end is hinged to the end of the outer swing pin; the two ends of the middle swing pin are respectively fixedly connected with guide plates perpendicular to the support beams, and each guide plate located on both sides of the middle swing pin is respectively provided with a sliding hole along the axial direction of the guide plate; the inner swing pin and the outer swing pin respectively pass through and slide in the corresponding sliding holes; the inner swing pin, the middle swing pin and the outer swing pin are respectively sleeved with a cylindrical irradiator.

[0008] A telescopic cylinder is arranged on the inner side of the support beam adjacent to the swing sliding sleeve, and the outer end of the telescopic rod of the telescopic cylinder is connected with the limiting sleeve.

[0009] A driven gear is circumferentially arranged on the outer side wall of one end of the swing sleeve, and a driving gear meshing with the driven gear is arranged on one side. The driving gear is transmission-connected with a swing motor on one side, and the swing motor is fixedly connected to the swing shaft.

[0010] The bottom of the tray is provided with an embedded groove, the turntable rotatably fits in the groove and the notch edge protrusion of the groove is suitable for limiting the turntable; a pair of suspension rods are provided at the bottom of the turntable, the upper ends of the suspension rods are connected to the turntable, and the lower ends thereof are respectively connected to the two ends of the swing shaft.

[0011] A rotary motor is arranged on the tray, and a rotating shaft of the rotary motor passes through the tray and is transmission-connected with the turntable.

[0014] The beneficial effects achieved by the present invention are:

[0015] (1) The height of the illuminator is adjusted by using a lifting beam. The illuminator can move along the axial and radial directions of the headlight cover to adjust the distance between the illuminator and the concave surface of the headlight cover, and the distance can be adjusted following the change in the axial shape of the headlight cover. Multiple cylindrical irradiators with adjustable spacing can adapt to headlight covers with different opening widths. All cylindrical irradiators rotate as a whole around an axis parallel to the axial direction of the headlight cover, thereby adjusting the number of cylindrical irradiators facing the concave surface of the headlight cover. When the opening width of the headlight cover is narrow, a single cylindrical irradiator is directed toward the inside of the headlight cover to complete the irradiation of the concave surface. In addition, a single cylindrical irradiator is extended into the headlight cover to strengthen the irradiation of a local area with poor irradiation effect, so as to improve the uniformity of irradiation. When the opening width of the headlight cover is wide, all cylindrical irradiators are directed toward the concave surface of the headlight cover or extended into the headlight cover, so as to improve the uniformity of irradiation of the concave surface. In order to adapt to the opening width of the lampshade of different headlights, the spacing between the multiple cylindrical lamps can be adjusted so that the light emitted by all the cylindrical lamps can shine into the concave surface or all the cylindrical lamps can extend into the headlight cover for illumination.

[0016] (2) Since the lampshade is placed along the axial direction of the conveyor belt, the crossbeam is arranged along the axial direction of the conveyor belt, and the longitudinal beam slides along the crossbeam, the axial relative position of the illuminator and the lampshade can be adjusted; the longitudinal beam is arranged along the radial direction of the conveyor belt, and when the tray slides along the longitudinal beam, the radial relative position of the illuminator and the lampshade can be adjusted. The turntable rotates relative to the tray to adjust the angle between the illuminator and the lampshade in the horizontal plane. The swing sleeve rotates relative to the swing shaft to adjust the angle between the illuminator and the lampshade in the vertical plane.

[0017] (3) The inner and outer swing arms are driven to rotate relative to the swing pins by sliding the limit sleeve on the support beam, thereby driving the inner and outer swing pins to slide in their respective sliding holes to adjust the distance between the cylindrical lamps on the inner and outer swing pins and the cylindrical lamp on the middle swing pin, thereby adapting to vehicle headlight covers with different opening widths.

[0018] (4) The telescopic cylinder is used to drive the reciprocating movement of the limit sleeve, so as to adjust the distance between the inner and outer swing pins and the cylindrical irradiation lamps on the middle swing pin steplessly according to the needs.

[0019] (5) The swing motor, the driving gear and the driven gear are used to reciprocately adjust the rotation angle of the swing sleeve on the swing shaft, thereby adjusting the angle between the illuminator and the headlight cover in the vertical plane.

[0020] (6) The raised edge of the groove at the bottom of the tray is used to limit the turntable so that the turntable does not fall out of the tray during rotation, thereby maintaining the working stability of the suspension rod and swing shaft on the lower side of the turntable, that is, ensuring the working stability of the irradiator.

[0021] (7) A rotary motor is used to drive the turntable to rotate around the center line of the tray so as to adjust the angle between the illuminator and the headlight cover in the horizontal plane.

[0022] (8) The motor is used to drive the upper pulley to rotate forward and reverse, so as to move the longitudinal beam along the axial direction of the cross beam, so as to adjust the axial relative position of the illuminator and the headlight cover.

[0023] (9) The motor is used to drive the lower pulley to rotate forward and reverse to achieve the axial movement of the tray along the longitudinal beam so as to adjust the radial relative position of the illuminator and the headlight cover. BRIEF DESCRIPTION OF THE DRAWINGS

The lower column 801, the lower transmission shaft 802, and the lower pulley 803 constitute the lower driver 8.

[0044] The lower ends of the lower columns 801 are connected to the top of the tray 7. Figure 6 , Figure 8 and Fig.10 As shown, the tray 7 is circular and has a circular embedded groove at its lower end. The circular turntable 14 is arranged in the groove and the edge of the turntable 14 is blocked by the protrusion of the notch edge of the groove to limit the position, so that the turntable 14 can rotate in the groove and will not escape from the groove. At the same time, a through hole is opened in the center of the top of the tray 7, and the top of the tray is also connected to a rotary motor 1501 through a pair of pillars 1503.

The rotary motor 1501, the rotating shaft 1502, and the pillars 1503 constitute a rotary driver 15.

[0045] A pair of suspension rods 9 are connected to the bottom end of the rotating disk 14, and each suspension rod 9 passes through the notch of the groove. Figure 4 and Figure 6 As shown, the lower end of each suspension rod 9 is fixedly connected to the two ends of a pair of horizontal swing shafts 10, respectively. A swing sleeve 11 is coaxially rotatably sleeved on the outer middle part of the swing shaft 10, and a driven gear 1304 is circumferentially arranged at one end of the swing sleeve 11. A swing motor 1302 is connected to the swing shaft 10 adjacent to the driven gear 1304 through a fixed block 1301. The outer end of the rotating shaft of the swing motor 1302 is coaxially connected to a driving gear 1303, and the driving gear 1303 is meshed with the driven gear 1304 for transmission.

The outer ends of the pair of support beams 1201 are fixedly connected to the two ends of the middle swing pin 1209 respectively, and the axis of the middle swing pin 1209 and the swing shaft 10 are parallel to each other. A guide plate 1215 is fixedly provided on the middle swing pin 1209 adjacent to each support beam 1201, and the pair of guide plates 1215 are parallel to each other and in a symmetric plane. Each guide plate 1215 is perpendicular to the support beam 1201 and in a symmetric plane with the support beam 1201. A pair of sliding holes 1214 are provided on each guide plate 1215 on both sides of the middle swing pin 1209 along the axial direction thereof, and the pair of sliding holes 1214 are in a symmetric plane with the support beam 1201. A cylindrical irradiation lamp 1211 is sleeved on the outer side of the middle part of the middle swing pin 1209 located between the pair of guide plates 1215.

[0047] like Figure 4 and Figure 6As shown, the outer sliding sleeve of the pair of support beams 1201 is provided with a limiting sleeve 1204, and the internal through hole of the limiting sleeve 1204 is exactly matched with the outer shape of the pair of support beams 1201, so that the fitting surface between the limiting sleeve 1204 and the pair of support beams 1201 can achieve relative sliding without gap. The limiting sleeve 1204 is provided with a swing pin 1205 at both ends along the axial direction of the swing shaft 10, and each swing pin 1205 is provided with an inner swing rod 1207 and an outer swing rod 1206 from the inside to the outside, and the inner and outer swing rods are respectively hinged with the corresponding swing pin 1205 through the hinge hole at one end thereof, and the outer end of each swing pin 1205 is provided with a limiting block (not shown in the figure), so as to limit the inner and outer swing rods along the axial direction of the swing pin. The other end of each inner swing rod 1207 is respectively hinged to the two ends of the inner swing pin 1210, and the inner swing pin 1210 is inserted into the sliding hole 1214 at the same end of the pair of guide plates 1215, and the inner swing pin 1210 and the sliding hole 1214 are suitable for sliding cooperation. A cylindrical irradiation lamp 1211 is sleeved on the outer wall of the inner swing pin 1210 located on the inner side of the pair of guide plates 1215. The two ends of each inner swing pin 1210 are respectively provided with a limit block (not shown in the figure), so as to limit the inner swing rod 1207 along the axial direction of the inner swing pin 1210. The other end of each outer swing rod 1206 is respectively hinged to the two ends of the outer swing pin 1208, and the outer swing pin 1208 is inserted into the sliding hole 1214 at the other end of the pair of guide plates 1215, and the outer swing pin 1208 and the sliding hole 1214 are also suitable for sliding cooperation. A cylindrical irradiation lamp 1211 is also sleeved on the outer side wall of the outer swing pin 1208 located inside the pair of guide plates 1215. Limit blocks (not shown) are respectively provided at both ends of each outer swing pin 1208, so as to limit the outer swing rod 1206 along the axial direction of the outer swing pin 1208.

[0048] like Figure 6 As shown, a telescopic cylinder 1203 is provided between a pair of support beams 1201 adjacent to the swing sleeve 11, and the telescopic cylinder 1203 is fixedly connected to the pair of support beams 1201 through a pair of support blocks 1202. The telescopic rod 1212 of the telescopic cylinder 1203 is parallel to the support beam 1201, and the outer end of the telescopic rod 1212 is fixedly connected to the connecting block 1213, and the connecting block 1213 is arranged in the internal through hole of the limiting sleeve 1204 between the pair of support beams 1201 and is fixedly connected to the inner wall of the limiting sleeve 1204.

[0050] As a preference, the lifting cylinder 3 and the telescopic cylinder 1203 may be pneumatic cylinders or hydraulic cylinders; or a screw mechanism driven by a motor may be used to replace the lifting cylinder or the telescopic cylinder.

[0051] As a preference, the motor in the upper column 601, the motor in the lower column 801, the swing motor 1302 and the rotary motor 1501 may be servo motors or stepper motors.

[0052] As a preferred embodiment, the present invention also includes a controller, which is signal-connected with the lifting cylinder 3, the telescopic cylinder 1203, the motor in the upper column 601, the motor in the lower column 801, the cylindrical irradiation lamp 1211, the swing motor 1302 and the rotary motor 1501 to control their operation.

[0053] As a preferred embodiment, the wires of the cylindrical irradiation lamp 1211 pass through the threading holes inside the outer swing pin 1208, the middle swing pin 1209, and the inner swing pin 1210 and come out from the side to prevent the wires from blocking the UV light emitted from the front of the cylindrical irradiation lamp.

[0054] As a preference, the cylindrical irradiation lamp 1211 may have a built-in battery, thereby preventing various arrangements of wires in the irradiator 12 from affecting the movement of the irradiator 12 and the irradiation process.

[0055] The working principle of the UV irradiation device for the concave surface of the special-shaped through-type vehicle lamp cover of the present invention is as follows:

[0056] In the production workshop, the special-shaped through-type headlight covers 1 are placed on the conveyor belt 2 at a certain distance. As the conveyor belt 2 moves, each special-shaped through-type headlight cover 1 is sequentially sent to the front of the UV irradiation device and paused. At this time, a pair of lifting cylinders 3 work synchronously, and the height of the crossbeam 4 and the height of the irradiator 12 are adjusted by moving a pair of lifting rods 302. At the same time, a pair of upper pulleys 603 roll in a set direction, thereby driving the longitudinal beam 5 to move to a set position along the axial direction of the crossbeam 4, and adjusting the distance between the irradiator 12 and the special-shaped through-type headlight cover 1 along the length direction of the headlight cover (i.e., Figure 1 A pair of lower pulleys 803 roll in a set direction, thereby driving the tray 7 to move to a set position along the axial direction of the longitudinal beam 5, thereby adjusting the irradiator 12 and the special-shaped through-type headlight cover 1 along the thickness direction of the headlight cover (i.e., Figure 1The rotary motor 1501 works and drives the turntable 14 to rotate a set angle, thereby adjusting the angle between the illuminator 12 and the headlight cover in the horizontal plane. The swing motor 1302 works and drives the swing sleeve 11 to rotate a set angle, thereby adjusting the angle of the support beam 1201 in the illuminator 12 relative to the horizontal plane, that is, the angle between the illuminator 12 and the headlight cover in the vertical plane. The telescopic cylinder 1203 works and drives the limit sleeve 1204 to move along the support beam 1201, so that the outer swing rod 1206 and the inner swing rod 1207 rotate around the swing pin 1205, and the outer swing pin 1208 and the inner swing pin 1210 slide along their respective sliding holes 1214, thereby adjusting the distance between the cylindrical irradiation lamp 1211 on the outer swing pin 1208, the inner swing pin 1210 and the cylindrical irradiation lamp 1211 on the middle swing pin 1209, so as to concentrate (or reduce) or expand the irradiation range of the three cylindrical irradiation lamps.

[0057] like Fig.11 As shown, when the illuminator 12 irradiates the concave surface of the small housing 102, since the opening width (or inner diameter) of the small housing 102 is smaller than the overall height of the illuminator 12, the support beam 1201 can be made vertical, the outer swing pin 1208 and the inner swing pin 1210 can be moved to the outer end along their respective slide holes 1214, and the cylindrical irradiation lamp 1211 on the outer swing pin 1208 or the inner swing pin 1210 can be aligned with the concave surface of the small housing 102 for irradiation. Fig.12 As shown, in order to irradiate the blind spots of the top wall or bottom wall of the small cover 102, the uniformity of irradiation is further improved. During the irradiation process, the tray 7 is driven to move along the axial direction of the longitudinal beam 5, and the distance between the irradiator 12 and the headlight cover along the thickness direction of the headlight cover (i.e., the Y direction) is adjusted; at the same time, the swing motor 1302 is adjusted to make the cylindrical irradiation lamp 1211 adjacent to the headlight cover tilt up or down, and the relative position of the cylindrical irradiation lamp 1211 and the small cover 102 is adjusted, so that the irradiation light intensity and irradiation time of the concave surface of the small cover 102 along the arc circumference are more uniform. In the above irradiation process, the irradiation of the entire concave surface of the small cover 102 is completed by driving the longitudinal beam 5 to move along the cross beam 4.

[0058] like Fig.13As shown, when the irradiator 12 irradiates the large housing 101, if the opening width of the concave surface of the large housing 101 is smaller than the distance between the cylindrical irradiation lamps 1211 on the outer swing pin 1208 and the inner swing pin 1210, the telescopic cylinder 1203 can be used to drive the limit sleeve 1204 to move, so that the outer swing pin 1208 and the inner swing pin 1210 move toward each other to reduce the distance between the cylindrical irradiation lamps 1211 on both sides, thereby concentrating the irradiation range of the three cylindrical irradiation lamps 1211, and allowing the three cylindrical irradiation lamps 1211 to extend into or partially extend into the inner side of the large housing 101, thereby improving the irradiation light intensity and irradiation uniformity of the concave surface of the large housing 101. Fig.14 As shown, if the opening width of the concave surface of the large housing 101 is greater than the distance between the cylindrical irradiation lamps 1211 on the outer swing pin 1208 and the inner swing pin 1210, the three cylindrical irradiation lamps 1211 can be extended into the inner side of the large housing 101, thereby improving the irradiation light intensity and irradiation uniformity of the concave surface of the large housing 101. If the opening width of the concave surface of the large housing 101 is much greater than the distance between the cylindrical irradiation lamps 1211 on the outer swing pin 1208 and the inner swing pin 1210, the telescopic cylinder 1203 can be used to drive the limit sleeve 1204 to move, so that the outer swing pin 1208 and the inner swing pin 1210 move in the opposite direction to their respective outermost sides, so that the three cylindrical irradiation lamps 1211 extend into the inner side of the large housing 101, and at the same time, the reciprocating movement of the lifting cylinder 3 is used to continuously adjust the height of the three cylindrical irradiation lamps 1211 inside the large housing 101, thereby improving the irradiation light intensity and irradiation uniformity of the inner surface of the top and bottom of the large housing 101.

[0059] like Fig.15 As shown, when the irradiator 12 irradiates the curved part of the large cover shell 101, the rotary motor 1501 is needed to adjust the direction of the support beam 1201 so that the three cylindrical irradiation lamps 1211 face the desired irradiation position of the concave inner surface of the large cover shell 101.
