Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying technology, specifically to a spraying device for notebook computer casings. Background Technology
[0002] While existing laptop casing coating devices are equipped with advanced robots (such as six-axis robots) capable of flexible multi-angle spraying and ensuring high-quality coating results, and typically include laptop casing supports in the coating area, the inventors have discovered the following technical problems in practical applications:
[0003] To increase the radiation range of a single spray and the number of laptop casings sprayed in one go, it is necessary to increase the number of six-axis robots, which results in high overall production costs. Utility Model Content
[0004] The present invention aims to provide a spraying device for laptop manufacturing shells to solve the problem of increased costs caused by the need to increase the number of products sprayed at one time.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A notebook computer casing spraying device includes a spraying area, a support within the spraying area, and a spraying structure for spraying products placed on the support; it also includes a support rod fixed within the spraying area; the support includes a base, a swing arm, a frame on the swing arm, and a drive component for driving the base to rotate, the base has a protrusion on its top, the swing arms are symmetrically arranged on the base, and the ends of the swing arms that are close to each other are movably connected to the protrusion; and when the swing arm is in a horizontal state, there is a gap between its bottom and the top surface of the base;
[0007] Each swing arm is equipped with a frame, and the support rod is located below the frame and is used to support the frame; the bottom surface of the frame protrudes from the bottom surface of the swing arm; the distance between the outer edges of the two support rods is less than the distance between the two frames.
[0008] Preferably, as an improvement, the frame includes a base frame and a support column for contacting the inner frame of the product, the support column being vertically fixedly connected to the base frame.
[0009] Preferably, as an improvement, the base frame has rounded corners on the side near the base.
[0010] Preferably, as an improvement, the spraying area includes a paint collection pool and a enclosure surrounding the paint collection pool, with one side of the spraying area being open.
[0011] Preferably, as an improvement, the spraying structure includes a spraying arm and a spraying bracket disposed at the lower end of the spraying arm. The spraying bracket is equipped with a nozzle for spraying the product on the frame, and the lateral span area of the spraying bracket corresponds to at least two brackets.
[0012] Preferably, as an improvement, the protrusion is covered with a deformable protective cover, the lower end of which is fixed to the top of the base.
[0013] Beneficial effects:
[0014] 1. Low modification cost and comprehensive spraying capability. This technology improves the support structure, allowing multiple supports to be added within the spraying area to hold laptop casings. Furthermore, by installing a spraying bracket at the end of the spraying arm, multiple nozzles can be arranged horizontally without the need for additional spraying arms, reducing overall costs. Moreover, each set of supports can compactly hold two laptop casings. During rotation, the support detaches from the support rod, and the swing arm tilts slightly downwards, exposing the opposite sides of the two laptop casings. This means the two casings can be placed close together without occupying excessive space. This technology eliminates the need to insert the spraying bracket between the two casings for touch-up coating. Therefore, this technology can increase the number of products that can be sprayed at one time within a limited space at a lower procurement and modification cost, greatly improving processing efficiency and ensuring coating quality.
[0015] 2. The rounded corners on the side of the base frame near the base improve the smoothness of the transition from the base frame to the support rod when the swing arm rotates.
[0016] 3. Cover the protrusion with a deformable protective cover to protect the hinge between the swing arm and the protrusion. For example, it can reduce or even prevent paint and other coating materials from directly entering the hinge and accumulating in large quantities, thus ensuring smooth rotation.

[0026] Example 1
[0027] As attached Figure 1-5 As shown, the notebook computer casing spraying device includes a spraying area, a support 6, a spraying structure, and a support rod 4 fixed within the spraying area. The spraying area includes a paint collection tank 1 and a perimeter enclosure 2 surrounding the top of the paint collection tank 1; in this embodiment, the enclosure 2 is a wall. The front of the spraying area is open. The spraying structure includes a spraying arm 3 and a spraying support 31 located at the lower end of the spraying arm 3. In this embodiment, the spraying arm 3 can specifically be a six-axis robot. Two nozzles 32 are mounted on the spraying support 31 for spraying the products on the support 6, respectively located near both ends of the spraying support 31, with each nozzle 32 corresponding to one support 6. Figure 1 As shown, a slide rail 5 is provided on the inner rear wall of the enclosure 2, and a slider is slidably mounted on the slide rail 5. The spraying arm 3 is fixed on the slider, so that the spraying arm 3 can slide left and right along the slide rail 5. The full spraying of the laptop shell product is achieved by using the left and right sliding and the forward and backward extension and angle adjustment of the spraying arm 3.
[0028] To accommodate the placement of the laptop casing, the bracket 6 in this embodiment includes, as follows: Figure 3The diagram shows a base 61, a swing arm 62, a frame 7 mounted on the swing arm 62, and a drive unit for rotating the base 61, specifically a motor. The base 61 is cylindrical, with a protrusion 611 at the center of its top. The swing arms 62 are symmetrically arranged on both sides of the base 61, with the ends of the swing arms 62 close to each other being rotatably connected to the protrusion 611 via shafts. When the swing arm 62 is in a horizontal state, there is a gap 63 between its bottom and the top surface of the base 61, allowing the swing arm 62 to flexibly extend downwards when unsupported. Figure 5 The tilted position shown allows the two laptop shells to unfold upwards and expose their opposite sides, facilitating a secondary coating application and ensuring coating quality.
[0029] Each swing arm 62 is equipped with a frame 7, the frame 7 including, as shown in the figure Figure 3 The base frame 71 and the support pillars 72 for contacting the inner frame of the laptop casing are shown. The support pillars 72 are vertically fixed to the base frame 71. In this embodiment, there are four support pillars 72, each supporting one of the four corners of the laptop casing. The top surface of the support pillars 72 is fixed with either a rubber layer or a suction cup to facilitate further fixation and anti-slip of the laptop casing. The base frame 71 consists of four support rods vertically fixed to the side wall of the swing arm 62, and the support rods are symmetrically arranged in pairs on the swing arm 62. The support rod 4 is fixed to the left side enclosure 2 and the right side enclosure 2, and the support rod 4 is located below the frame 7, as shown. Figure 1 In the indicated state, the support rod 4 and the swing arm 62 are horizontally positioned, and the support rod 4 contacts and supports the bottom of the frame 7 to maintain its horizontal state. When the motor drives the swing arm 62 to rotate... Figure 2 In the state, combine Figure 3 As shown, since the distance A between the outer edges of the two support rods 4 is less than the distance B between the two sets of frames 7, the two support rods 4 will be located between the base 61 and the base frame 71 respectively, and the support rods 4 will no longer support the bottom of the frame 7; since the bottom surface of the swing arm 62 is higher than the bottom surface of the base frame 71, and there is a gap 63 between the bottom of the swing arm 62 and the top surface of the base 61 when the swing arm 62 is in a horizontal state, the swing arm 62 will swing downward by a small arc after being freed from the support of the support rods 4, causing the swing arm 62 to tilt and form Figure 5 As shown in the diagram. The base frame 71 has a rounded corner on the side near the base 61. A deformable protective cover is provided at the protrusion 611. The lower end of the protective cover is fixed to the top of the base 61, and its edge that contacts the swing arm 62 is bonded and sealed to the swing arm 62. The protective cover can be made of materials such as corrugated pipe, elastic rubber layer, or waterproof fabric. The design can leave a margin according to the swing range, so as not to affect the rotation of the swing arm 62 while achieving the protective effect.
[0030] The operating method of the notebook computer casing spraying equipment is as follows:
[0031] like Figure 1As shown, the laptop casing is placed on the support column 72 with the recessed side facing each other on the frame 7, allowing four products to be placed at once. The spraying process is started by pressing the button; the spraying arm 3 slides left and right along the slide rail 5, then moves forward, achieving full spraying of the product through the left-right sliding and forward movement of the nozzle 32. A second coat is then applied. Before the second coat, the base 61 is rotated using a motor, causing the entire frame 7 to rotate around... Figure 1 Rotation in the direction indicated by the middle arrow forms Figure 2 The state, combined Figure 3 As shown, since the bottom surface of the swing arm 62 is higher than the bottom surface of the base frame 71, and there is a gap 63 between the bottom of the swing arm 62 and the top surface of the base 61 when the swing arm 62 is in a horizontal state, when the swing arm 62 is rotated to a direction perpendicular to the support rod 4, the swing arm 62 will swing downward by a slight arc, causing the swing arm 62 to tilt. The tilted swing arm 62 will be well supported by the base 61. After the swing arm 62 has rotated, the spraying bracket 31 is located at... Figure 1 On the front side, the spray arm 3 adjusts its angle to drive the nozzle 32 downward to spray the front edge of the rotated product. Then it moves backward and back and forth to spray. During this process, because the two swing arms 62 tilt downward, the opposite side of the product unfolds upward. Therefore, during the recoating, the opposite edge of the product can also be sprayed, achieving the purpose of full coating. Until the spray bracket 31 is in position... Figure 1 The rear edge of the rotated product is sprayed in the same way as above. After the second spraying is completed, the motor drives the base frame 71 to continue rotating. Since the base frame 71 has rounded corners on the side near the base 61, it can climb along the arc surface to the support rod 4, and finally the swing arm 62 is supported by the support rod 4 to return to the horizontal state. In other embodiments besides this one, this bracket 6 can also be used for multiple sprayings, for example, it can be sprayed back and forth more than twice. In addition, it is worth noting that due to the unique design of this bracket 6, the spraying bracket 31 only needs to move back and forth and swing up and down at a certain angle when it moves to the front or rear. Therefore, the spraying arm 3 does not have to use the six-axis robot used in the original factory. Other intelligent robotic arms that can achieve forward and backward movement and up and down swing angles can also be used.
[0032] Example 2
[0033] like Figure 6 , Figure 7As shown, multiple sets of supports 6 are set in the spraying area. In this embodiment, three sets are used as an example. Three sets of nozzles 32 are also set, each corresponding to a support 6. This design allows for the spraying of six products at once without the need for additional robots such as spraying arms 3. By using multiple nozzles 32 set in the spraying support 31, combined with the unique support 6 design of this technology, it is possible to ensure that multiple products can be sprayed comprehensively and at once.
