Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a sheet metal surface spraying device. Background Art

[0002] Sheet metal parts refer to metal structural parts made by shearing, bending and forming metal sheets. Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost and good performance in large-scale mass production. They have been widely used in the fields of electronics, communications, automobile industry and medical equipment. In order to improve the appearance and service life of sheet metal parts, or to use them in special environments, they are usually painted on the outside. Most existing sheet metal parts are clamped and fixed by clamps during painting, resulting in unpainted areas at the clamping parts of the sheet metal parts. These areas usually need to be supplemented manually. The processing process is relatively cumbersome and easily leads to color difference in the paint surface, thus affecting the efficiency and effect of painting. Utility Model Content

[0003] The purpose of the utility model is to provide a sheet metal surface painting device to address the above-mentioned shortcomings, so as to ensure the efficiency and effect of the sheet metal surface painting.

[0006] A power device, used for driving the two clamping devices to move closer to each other or away from each other;

[0007] A paint spraying device, which moves in a circular manner with the center of the paint spraying platform as the midpoint after being started, and the paint spraying device also includes a lifting device and a spray head arranged at the lifting end of the lifting device;

[0008] A contact plate is vertically arranged on the paint spraying device, and is used to contact and push the telescopic contact devices downward in sequence when the paint spraying device moves, so that the clamping parts in contact with the corresponding telescopic contact devices rotate to a side away from the sheet metal part and separate from the sheet metal part;

[0009] The drying device is arranged on the paint spraying device and is used for drying the part where the paint spraying is completed and the clamping part is not in contact with the sheet metal part.

[0010] Furthermore, the power device includes a rotatable screw which is laterally arranged on the paint spraying table and has two opposite threads. The paint spraying table is provided with a first motor for driving the screw to rotate. The corresponding two threads of the screw are provided with movable frames that cooperate with it. The other end of each movable frame away from the screw is connected to a clamping device. The first motor is used to drive the two clamping devices to move closer to or away from each other to clamp the sheet metal so that the sheet metal is sprayed with paint.

[0011] Furthermore, the clamping portion includes a clamping plate hingedly arranged on the bottom plate, the outer side of the clamping plate is wrapped with a soft layer, and the soft layer contacts the sheet metal part.

[0012] Furthermore, a gear ring is provided on the paint spraying table, and the paint spraying device includes a support arranged on the gear ring and capable of sliding in a circular shape on the gear ring, a rotatable gear arranged on the support, and a second motor arranged on the support for driving the gear to rotate. The rotation of the gear is used to drive the support to move in a circular shape with the center of the gear ring as the center, and a pulley is rotatably provided at the bottom of the support.

[0013] Furthermore, the telescopic contact device includes a rod body connected to the clamping plate at one end, a sleeve sleeved on the other end of the rod body, and a rolling ball rotatably arranged on the end of the sleeve away from the rod body. A spring is arranged on the inner wall of the sleeve, and the other end of the spring is connected to the end of the rod body close to the sleeve. The rolling ball contacts the inner wall of the ring gear. The telescopic contact device is used to ensure that the resistance plate that moves in a circular motion with the paint spraying device will still contact with and push the telescopic contact device after the two clamping devices approach or move away from each other.

[0014] Furthermore, an anti-skid layer is provided on the bottom plate, and the other end of the anti-skid layer away from the bottom plate is in contact with the sheet metal part.

[0015] Furthermore, a ring-shaped anti-slip groove is provided on the top wall of the gear ring, and an anti-slip plate inserted into the anti-slip groove is provided at the bottom of the support.

[0016] The beneficial effects of the utility model are embodied in:

[0017] The utility model starts the paint spraying device, causes the spray head to rotate and rise and fall to spray paint on the clamped sheet metal part, and stops after the paint spraying device rotates until the contact plate approaches and abuts the telescopic contact device.

[0023] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3The utility model discloses a sheet metal surface painting device, including a painting platform 1, on which two clamping devices 5 are slidably arranged, the clamping device 5 includes a bottom plate 52 and a plurality of clamping parts hingedly arranged on the bottom plate 52, one side of each clamping part contacts the side wall of the sheet metal, a torsion spring is provided at the connection between each clamping part and the bottom plate 52, and a telescopic contact device is provided on the side of each clamping part away from the sheet metal, and a power device is provided on the painting platform 1, which is used to drive the two clamping devices 5 to move closer to or away from each other.

[0025] In one embodiment, the device also includes a paint spraying device 7. After the paint spraying device 7 is started, it will move in a circular shape with the center of the paint spraying table 1 as the midpoint. The paint spraying device 7 also includes a lifting device 75 and a nozzle 76 installed at the lifting end of the lifting device 75. The lifting device 75 can be a vertically arranged linear module. After the linear module is started, it is used to control the nozzle 76 to perform lifting and lowering movements. The nozzle 76 can be connected to a paint source through a pipeline and a pump body device. When in use, the pump body device can be started to absorb the paint and spray it out from the nozzle 76. A resistance plate 77 is vertically installed on the paint spraying device 7. The resistance plate 77 is used to contact and push the telescopic contact device downward in turn when the paint spraying device 7 moves, so that the clamping part in contact with the corresponding telescopic contact device rotates to the side away from the sheet metal and separates from the sheet metal. A drying device 10 is provided on the paint spraying device 7. The drying device 10 can be a hot air blower, which is used to dry the part where the paint is sprayed and the clamping part is not in contact with the sheet metal.

[0026] In a specific implementation, the staff controls the two clamping devices 5 to move closer to or away from each other through a power device, and after adjustment, they are used to clamp the sheet metal parts, and then the paint spraying device 7 is started. The paint spraying device 7 drives the nozzle 76 to move in a circular shape around the sheet metal parts, so as to spray the paint onto the sheet metal parts. The lifting device 75 is used to control the lifting and movement of the nozzle 76, so that the nozzle 76 can paint the sheet metal parts more accurately. In this process, when the paint spraying device 7 rotates until the contact plate 77 approaches and abuts the telescopic contact device, it stops. At this time, the telescopic contact device will rotate downward after being abutted, and the clamping part will be connected with the bottom plate 52 as The center is rotated toward the side away from the sheet metal, so that the clamping part is separated from the sheet metal. After the part of the sheet metal is exposed, it is convenient for the nozzle 76 to spray paint. Since there are multiple clamping parts on the bottom plate 52, the separation of one clamping part from the sheet metal will not affect the stable clamping of the sheet metal by the clamping device 5. Moreover, after the exposed part is painted, the paint spraying device 7 can continue to rotate, so that the contact plate 77 abuts against another telescopic contact device to continue painting. This method can effectively paint the clamping part of the sheet metal without the need for subsequent touch-up paint by the staff, so as to ensure the efficiency and effect of painting the surface of the sheet metal.

[0027] It can be understood that the telescopic contact device has a telescopic function, and its minimum length and maximum length can contact the contact plate 77. Therefore, when the two clamping devices 5 approach each other and move away from each other, the contact plate 77 can contact the telescopic contact device as the paint spraying device 7 rotates, so that the device can paint sheet metal parts of different sizes. When the paint at the clamping position is sprayed, the drying device 10 can be started to increase the drying efficiency of the paint through the drying device 10, thereby further improving the painting efficiency of the sheet metal parts.

[0028] In one embodiment, the power device includes a rotatable screw 2 which is horizontally arranged on the paint spraying table 1 and has two opposite threads. A first motor 3 is installed on the paint spraying table 1 to drive the screw 2 to rotate. The corresponding two threads of the screw 2 are movably installed with a movable frame 4 that cooperates with it. The other end of each movable frame 4 away from the screw 2 is connected to a clamping device 5. The first motor 3 is used to drive the two clamping devices 5 to move closer to or away from each other to clamp the sheet metal so that the sheet metal is sprayed with paint.

[0029] This design allows the installation position of the lead screw 2 and the first motor 3 to be staggered with the paint spraying position of the paint spraying station 1 to prevent the paint from contacting the lead screw 2 and the first motor 3 to affect the adjustment of the clamping device 5 .

[0030] In one embodiment, the clamping portion includes a clamping plate 53 hingedly disposed on the bottom plate 52 , and the outer side of the clamping plate 53 is wrapped with a soft layer, which may be a silicone layer, and the soft layer is used to contact the sheet metal part.

[0031] With this design, when the contact plate 77 is separated from the telescopic contact device, the corresponding clamping part will return to its original position driven by the torsion spring and continue to clamp the sheet metal part, and the provision of the soft layer can prevent the clamping part from causing damage to the surface of the sheet metal part when returning to its original position.

[0032] In one embodiment, a gear ring 6 is installed on the paint spraying station 1, and the paint spraying device 7 includes a support 71 arranged on the gear ring 6 and can slide in a ring shape on the gear ring 6, a gear 72 rotatably installed on the support 71, and a second motor 73 installed on the support 71 for driving the gear 72 to rotate, and a pulley 74 is rotatably provided at the bottom of the support 71.

[0033] With this design, when the second motor 73 is started, the gear 72 rotates and drives the support 71 to move in a circular shape with the center of the ring gear 6 as the center, and the pulley 74 contacts the placement surface, so that the paint spraying device 7 can be moved and adjusted stably and smoothly.

[0034] In one embodiment, the telescopic contact device includes a rod 54 connected to the clamping plate 53 at one end, a sleeve 55 sleeved on the other end of the rod 54, and a ball 56 rotatably installed on the end of the sleeve 55 away from the rod 54. A spring is installed on the inner wall of the sleeve 55, and the other end of the spring is connected to the end of the rod 54 close to the sleeve 55. The ball 56 contacts the inner wall of the ring gear 6. The telescopic contact device is used to ensure that the resistance plate 77 that moves in a circular motion with the paint spraying device 7 will still contact with it and push the telescopic contact device after the two clamping devices 5 approach or move away from each other.

[0035] In a specific implementation, when the two clamping devices 5 are close to each other, the spring will push the rod 54, so that the length of the rod 54 and the sleeve 55 will be lengthened. When the two clamping devices 5 are away from each other, the clamping plate 53 will push the rod 54, so that it will retract into the sleeve 55. This design enables the contact plate 77 to contact the sleeve 55 and drive the clamping plate 53 to rotate when the two clamping devices 5 are adjusted to any position.

[0036] In one embodiment, an anti-skid layer is installed on the bottom plate 52. The anti-skid layer may be a rubber layer with anti-skid patterns. The other end of the anti-skid layer away from the bottom plate 52 contacts the sheet metal. The anti-skid layer is used to make the sheet metal placed on the bottom plate 52 more stable.

[0037] In one embodiment, a ring-shaped anti-slip groove 8 is formed on the top wall of the gear ring 6 , and an anti-slip plate 9 inserted into the anti-slip groove 8 is installed at the bottom of the support 71 .

[0038] With such a design, when the paint spraying device 7 moves, the anti-slip plate 9 will synchronously move in a ring shape in the anti-slip groove 8, thereby making it difficult for the paint spraying device 7 to separate from the gear ring 6, thereby improving the adjustment stability of the paint spraying device 7.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).
