Description

Technical Field

[0001] This utility model relates to the field of parts spraying technology, and in particular to an automatic parts spraying device for a parts production line. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the coating to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.

[0003] In the prior art, Chinese patent application number 202221356516.6 discloses an automatic spraying device for an automotive painting production line, relating to the field of automotive painting technology. This automatic spraying device includes a base and a support frame. A transmission jack is rotatably connected to the side wall of the support frame. The transmission jack is connected to a second transmission jack via a conveyor belt. A rotary motor is installed inside the transmission jack. A fixed seat is fixedly connected to the surface of the base. A drive motor is fixedly connected to the side wall of the fixed seat. The output shaft of the drive motor passes through the side wall of the fixed seat and is rotatably connected to it. This automatic spraying device drives a rotating rod to rotate via the drive motor, causing a turntable to rotate and flip the parts. When the parts come into contact with the conveyor belt again, under the action of friction, the parts slide out of the slot and are transported to the bottom of another set of spraying equipment for spraying the back of the parts, thereby saving processing costs.

[0004] However, the above technical solutions have the drawback of achieving front-side spraying and automatic flip-side spraying of parts. However, there is no drying equipment to dry the paint surface between the parts and the flip-side. When the parts are inserted into the slots on the turntable, the paint surface will be damaged, affecting the quality of the spraying and failing to meet the usage requirements. Therefore, this application proposes an automatic spraying device for parts production line to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, which, although they achieve front-side spraying and automatic flip-side spraying of parts, lack drying equipment between side-swapping operations to dry the paint surface. When parts are inserted into the slots on the turntable, the paint surface is damaged, affecting the spraying quality and failing to meet usage requirements. Therefore, this invention proposes an automatic spraying device for parts production lines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automated spraying device for a parts production line includes a base plate, on the top of which a conveyor belt is fixedly mounted. The spraying device also includes: The side plates are configured as two, and the bottom ends of the two side plates are fixedly installed on the top of the base plate, and the side plates are respectively set on the front and rear sides of the conveyor belt; The spraying equipment is provided in two parts, and both spraying equipment are fixedly installed on the top of the base plate; The drying assembly consists of two components: a support frame, a drying device, two first electric push rods, two connecting rods, and two baffles. The bottom of the support frame is fixedly mounted on the top of the base plate. The drying device is fixedly mounted on the top of the support frame and communicates with the interior of the support frame. The two first electric push rods are fixedly mounted on the front and rear sides of the support frame, respectively. The bottom of the connecting rod is fixedly mounted on the output shaft of the corresponding first electric push rod. The two baffles are slidably connected to the left and right sides of the support frame, respectively. The left and right ends of the connecting rods are fixedly mounted on the two baffles, respectively. A flipping assembly is disposed on the top of the base plate and is used to flip the parts over.

[0007] As a preferred embodiment of this utility model, the bracket has four limiting grooves on both the left and right sides, and one side of the baffle is slidably connected to two limiting grooves on the same side.

[0008] In a preferred embodiment of this utility model, the flipping assembly includes two second electric push rods, two sliders, two third electric push rods, two mounting blocks, two motors, and two clamping plates. The two second electric push rods are fixedly mounted on the top of the base plate. The sides of the two sliders that are furthest from each other are fixedly mounted on the output shafts of the two second electric push rods. The bottom ends of the two sliders are slidably connected to the top of the base plate. The third electric push rods are fixedly mounted on the tops of the corresponding sliders. The bottom of the mounting blocks is fixedly mounted on the output shafts of the corresponding third electric push rods. The motors are fixedly mounted on one side of the corresponding mounting blocks. The sides of the two clamping plates that are furthest from each other are fixedly mounted on the output shafts of the two motors. The tops of the two side plates are each provided with an adapter groove, and the clamping plates are positioned within the corresponding adapter grooves.

[0009] As a preferred embodiment of this utility model, the top of the base plate has two sliding grooves, and the bottom end of the slider is slidably connected in the corresponding sliding groove.

[0010] As a preferred embodiment of this utility model, telescopic rods are fixedly installed on both the left and right sides of the slider, and the top ends of the two telescopic rods are fixedly installed on the left and right sides of the mounting block, respectively.

[0011] As a preferred embodiment of this utility model, a stabilizing frame is rotatably sleeved on the output shaft of the motor, and one end of the stabilizing frame is fixedly installed on the left and right sides of the corresponding mounting blocks.

[0012] As a preferred embodiment of this utility model, rubber pads are fixedly installed on the sides of the two clamping plates that are close to each other.

[0013] Beneficial effects: 1. In order to solve the problem that the parts cannot be dried after being painted on one side, the painted parts are transported to the inside of the bracket by a conveyor belt. At this time, the first electric push rod is activated, which drives the two connecting rods to move down. Then the two connecting rods will drive the two baffles to move down, thereby sealing the inlet and outlet on both sides of the bracket to reduce heat loss. Then the drying equipment is activated to dry the paint on the surface of the parts. 2. To achieve the flipping and reversing of parts, when the parts are conveyed to the space between the two clamping plates by the conveyor belt, the activation of the two second electric push rods drives the two sliders, two third electric push rods, two mounting blocks, two motors, and two clamping plates to move closer together. At this time, the two clamping plates can clamp and fix the parts. Then, the activation of the two third electric push rods drives the two mounting blocks, two motors, two clamping plates, and parts to rise. After the parts are raised, the activation of the motors drives the two clamping plates and parts to rotate, thus achieving the flipping and reversing of the parts. Then, through the reverse transmission of the above structure, the parts can be lowered and placed on the top of the conveyor belt for subsequent spraying and drying operations via the conveyor belt. This invention achieves the flipping and conversion of parts through a simple structure, enabling double-sided spraying and double-sided drying of parts, improving the processing efficiency and effect of parts, and is easy to operate and highly practical.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example Reference Figures 1-4 An automated spraying device for a parts production line includes a base plate 1, a conveyor belt 2 fixedly mounted on the top of the base plate 1, and the spraying device further includes: Side plates 3 are provided, and the bottom ends of the two side plates 3 are fixedly installed on the top of the base plate 1. The side plates 3 are respectively set on the front and rear sides of the conveyor belt 2. There are two spraying devices 4, both of which are fixedly installed on the top of the base plate 1. The drying assembly consists of two components: a support frame 5, a drying device 6, two first electric push rods 7, two connecting rods 8, and two baffles 9. The bottom of the support frame 5 is fixedly installed on the top of the base plate 1. The drying device 6 is fixedly installed on the top of the support frame 5 and communicates with the interior of the support frame 5. The two first electric push rods 7 are fixedly installed on the front and rear sides of the support frame 5, respectively.

The left and right ends of the connecting rods 8 are fixedly installed on the two baffles 9, respectively. The flipping assembly is located on the top of the base plate 1 and is used to flip the parts.

[0018] To solve the problem of parts not being able to dry after being painted on one side, such as Figure 1As shown, the parts are first placed on the top left side of the conveyor belt 2. The conveyor belt 2 then transports the parts to the spraying equipment 4 on the left for spraying. After spraying, the parts are transported by the conveyor belt 2 to the support 5 on the left. At this point, the first electric push rod 7 is activated, which moves the two connecting rods 8 downward. The two connecting rods 8 then move the two baffles 9 downward, thus sealing the inlet and outlet on both sides of the support 5 to reduce heat loss. Then, the drying equipment 6 is activated to dry the paint on the surface of the parts. After the parts are dried, the baffles 9 are opened and the parts are transported by the conveyor belt 2. Then, the parts are flipped over by the flipping assembly. The conveyor belt 2 then transports the parts to the spraying equipment 4 on the right for spraying on the other side.

[0019] In order to provide stable support for the movement of the baffle 9, the bracket 5 has four limit grooves 10 on the left and right sides. One side of the baffle 9 is slidably connected to two limit grooves 10 on the same side.

[0020] To achieve the flipping and reversing of parts, when the parts are conveyed to the space between the two clamping plates 18 via conveyor belt 2, activating the two second electric push rods 11 drives the two sliders 12, two third electric push rods 14, two mounting blocks 15, two motors 17, and two clamping plates 18 to move closer together. At this point, the two clamping plates 18 can clamp and fix the parts. Activating the two third electric push rods 14 then drives the two mounting blocks 15, two motors 17, two clamping plates 18, and parts to rise. After the parts are raised, activating the motors 17 drives the two clamping plates 18 and parts to rotate, thus flipping and reversing the parts. Then, through the reverse transmission of the above structure, the parts can be lowered and placed on top of conveyor belt 2 for subsequent spraying and drying operations via conveyor belt 2. The flipping assembly includes two second electric push rods 11, two sliders 12, two third electric push rods 14, two mounting blocks 15, two motors 17, and two clamping plates 18.

The top of the two side plates 3 is provided with an adapter groove 21, and the clamping plates 18 are set in the corresponding adapter groove 21.

[0021] In order to provide stable sliding support for the slider 12, two grooves 13 are provided on the top of the base plate 1, and the bottom end of the slider 12 is slidably connected in the corresponding grooves 13.

[0022] To improve the lifting stability of the mounting block 15, telescopic rods 16 are fixedly installed on the left and right sides of the slider 12, with the top ends of the two telescopic rods 16 fixedly installed on the left and right sides of the mounting block 15, respectively.

[0023] To improve the rotational stability of the output shaft of motor 17 and clamping plate 18, a stabilizing frame 20 is rotatably sleeved on the output shaft of motor 17, with one end of the stabilizing frame 20 fixedly installed on the left and right sides of the corresponding mounting block 15.

[0024] To improve the clamping stability of the parts, rubber pads 19 are fixedly installed on the sides of the two clamping plates 18 that are close to each other.

[0025] It should be noted that the specific models of conveyor belt 2, drying equipment 6, first electric push rod 7, second electric push rod 11, third electric push rod 14, and motor 17 used can be selected by those skilled in the art. Furthermore, the above-mentioned conveyor belt 2, drying equipment 6, first electric push rod 7, second electric push rod 11, third electric push rod 14, and motor 17 are all existing technologies, and this solution will not elaborate on them.

[0026] The spraying equipment 4 adopts existing technology and can be directly used with the structure of the patent with application number 202221356516.6, so it will not be described in detail.

In use, firstly, the conveyor belt 2, spraying equipment 4, drying equipment 6, first electric push rod 7, second electric push rod 11, third electric push rod 14, and motor 17 are connected to an external power source. Then, the parts are placed on the top left side of the conveyor belt 2. The conveyor belt 2 then transports the parts to the inside of the spraying equipment 4 on the left for spraying. After spraying, the parts are transported by the conveyor belt 2 to the inside of the support 5 on the left. At this point, activating the first electric push rod 7 causes the two connecting rods 8 to move downwards. Then, the two connecting rods 8 will... The two baffles 9 are moved down to block the inlets and outlets on both sides of the bracket 5, reducing heat loss. Then, the drying equipment 6 is started to dry the paint on the surface of the parts. After the parts are dried, the baffles 9 are opened and the parts are conveyed by the conveyor belt 2. Then, the parts are flipped over by the flipping component. At this time, the conveyor belt 2 conveys the parts to the spraying equipment 4 on the right side for spraying on the other side. Then, the conveyor belt 2 continues to convey the sprayed parts to the bracket 5 on the right side and is dried again by the drying equipment 6, thus realizing the spraying and drying operation on both sides of the parts.
