Description

Technical Field

[0001] This application relates to the field of SMT dispensing, and more specifically, to an SMT dispensing device with a positioning structure. Background Technology

[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). SMT is a technology that utilizes surface mount technology and is one of the most popular technologies and processes in the electronics assembly industry.

[0003] In the existing technology, PCB boards need to be glued during the SMT processing. However, traditional glue dispensing is done manually, which is time-consuming, labor-intensive and inefficient.

[0004] Chinese patent application CN202123063890.5 discloses an MT (Modular Component) dispensing device, comprising a processing box, a support, a glue holder, a mounting plate, a cylinder, a dispensing valve, and an intermittent feeding mechanism. The processing box has a door hinged to its side, an inlet on its side, and an outlet on its opposite side. The support is mounted on the processing box and extends through both the inlet and outlet. The glue holder is located on the top of the processing box. This device allows the PCB board to continuously pass through the dispensing valve, with a pause in the process to allow time for dispensing, thus saving manpower and improving efficiency.

[0005] The above solution also has the following shortcomings: During the dispensing process, the PCB board is transported by a belt and the dispensing valve is controlled to perform the dispensing operation on the PCB board. However, it is not easy to position the PCB board during the dispensing process, and it is easy to deviate during the transport process, which affects the dispensing quality and reduces the practicality of the device. Utility Model Content

[0006] To overcome the above shortcomings, this application provides an SMT dispensing device with a positioning structure, which aims to improve the problem that it is not easy to position the PCB board during the dispensing process, and that the deviation is easy to occur during the transportation process, thereby affecting the dispensing quality and reducing the practicality of the device.

[0007] This application provides an SMT dispensing device with a positioning structure, including a conveying structure and a positioning structure. The conveying structure includes a conveyor body, and the positioning structure includes two vertical plates, a lifting assembly, a first toothed plate, a linkage assembly, a positioning frame, springs, a sliding plate, and a positioning plate. The two vertical plates are fixedly connected to one side of the conveyor body. The lifting assembly is disposed on one side of the vertical plates. The first toothed plate is connected to the lifting assembly. The linkage assembly is disposed on one side of the vertical plates. The positioning frame is connected to the linkage assembly.

The top plate is fixedly connected to the movable end of the electric push rod. The first toothed plate is fixedly connected to both sides of the top plate. The first toothed plate is slidably connected to the support plate.

[0009] In the above implementation process, the setting of the support plate, electric push rod and top plate can easily drive the dispensing assembly to move, which facilitates dispensing, and at the same time, it can easily drive the first toothed plate to move.

The limiting frame is fixedly connected to one side of each of the two vertical plates. The second toothed plate is slidably connected to the limiting frame. The positioning frame is fixedly connected to the second toothed plate.

[0011] In the above implementation process, the two connecting plates, connecting shaft, gear, second toothed plate and limiting frame can be set up to easily move the two positioning plates closer and further apart, which facilitates the positioning of the PCB board and improves the dispensing effect.

[0012] In one specific implementation, a dispensing assembly is provided on one side of the top plate. The dispensing assembly includes a mounting plate and a dispensing machine body. The mounting plate is fixedly connected to the top plate, and the dispensing machine body is mounted on one side of the mounting plate.

[0013] In the above implementation process, the installation of the mounting plate and the main body of the dispensing machine facilitates the dispensing of adhesive onto the PCB board.

[0014] In one specific implementation, a collection assembly is provided on one side of the vertical plate. The collection assembly includes a rotating shaft, an L-shaped rotating plate, an L-shaped rotating rod, a torsion spring, a collection tube, and a collection cylinder. The rotating shaft is fixedly connected to the vertical plate. The L-shaped rotating rods are fixedly connected to both sides of the L-shaped rotating plate. The L-shaped rotating plate and the L-shaped rotating rods are rotatably connected to the rotating shaft. The torsion springs are fixedly connected to one side of each of the two L-shaped rotating rods. The torsion springs are fixedly connected to the rotating shaft. The collection tube is threadedly connected to the L-shaped rotating plate and communicates with the collection cylinder.

[0015] In the above implementation process, the setting of the rotating shaft, L-shaped rotating plate, L-shaped rotating rod, torsion spring, collecting tube and collecting cylinder can conveniently and timely collect the glue dripping from the dispensing nozzle of the dispensing machine body, and avoid excess glue dripping onto the PCB board and the conveyor body.

[0016] In one specific implementation, an L-shaped limiting rod is fixedly connected inside the conveyor body.

[0017] In the above implementation process, by fixing an L-shaped limiting rod inside the conveyor body, the PCB board being fed can be easily limited, which facilitates subsequent positioning.

[0018] In one specific implementation, a groove is provided on one side of the positioning frame, and the sliding plate is slidably connected to the groove.

[0019] In the above implementation process, the sliding connection between the skateboard and the chute makes it easy to limit the movement of the skateboard.

[0033] In the specific setup, an L-shaped limiting rod 130 is fixedly connected inside the conveyor body 110. By fixing the L-shaped limiting rod 130 inside the conveyor body 110, the PCB board being fed can be easily limited, facilitating subsequent positioning.

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The positioning structure 20 includes two vertical plates 210, a lifting assembly 220, a first toothed plate 230, a linkage assembly 240, a positioning frame 250, a spring 260, a sliding plate 270, and a positioning plate 280. The two vertical plates 210 are fixedly connected to one side of the conveyor body 110. The lifting assembly 220 is located on one side of the vertical plate 210. The first toothed plate 230 is connected to the lifting assembly 220. The linkage assembly 240 is located on one side of the vertical plate 210. The positioning frame 250 is connected to the linkage assembly 240. Several springs 260 are fixedly connected to one side of the sliding plate 270.

The support plate 221 is fixedly connected to one side of each of the two vertical plates 210. The electric push rod 222 is installed on one side of the support plate 221. The top plate 223 is fixedly connected to the movable end of the electric push rod 222. The first toothed plate 230 is fixedly connected to both sides of the top plate 223. The first toothed plate 230 is slidably connected to the support plate 221. The configuration of the support plate 221, the electric push rod 222, and the top plate 223 facilitates the movement of the dispensing assembly 290, which is convenient for dispensing. At the same time, the movement of the first toothed plate 230 is also convenient for moving.

[0036] In a specific configuration, the linkage component 240 includes two connecting plates 241, a connecting shaft 242, a gear 243, a second toothed plate 244, and a limiting frame 245. The two connecting plates 241 are arranged parallel to one side of the vertical plate 210. The connecting shaft 242 is rotatably connected to the connecting plates 241. The gear 243 is fixedly connected to the outer ring of the connecting shaft 242. The gear 243 meshes with the second toothed plate 244.

[0037] In a specific configuration, a dispensing assembly 290 is provided on one side of the top plate 223. The dispensing assembly 290 includes a mounting plate 291 and a dispensing machine body 292. The mounting plate 291 is fixedly connected to the top plate 223, and the dispensing machine body 292 is installed on one side of the mounting plate 291. The mounting plate 291 and the dispensing machine body 292 facilitate dispensing onto the PCB board.

[0038] In the specific setup, a groove is provided on one side of the positioning frame 250, and the slide plate 270 is slidably connected to the groove. The slidable connection between the slide plate 270 and the groove makes it easy to limit the movement of the slide plate 270.

[0039] The working principle of this SMT dispensing equipment with a positioning structure is as follows: When using the SMT dispensing equipment with a positioning structure, the user places the PCB board on the conveyor body 110 for conveying. The L-shaped limit rod 130 limits the PCB board. When the PCB board reaches directly below the dispensing assembly 290, the conveyor body 110 stops conveying. The electric push rod 222 drives the top plate 223 to descend, causing the dispensing machine body 292 fixed to the top plate 223 and the first toothed plate 230 to move downwards synchronously. The first toothed plate 230, through the meshing of gear 243 and the second toothed plate 244, drives the two positioning frames 250 to move closer together, and the positioning plate 280 contacts the two sides of the PCB board. The slide plate 270 continues to push the spring 260 to achieve flexible positioning. At the same time, when the dispensing assembly 290 descends, it pushes the L-shaped rotating rod 123 to make the L-shaped rotating plate 122 rotate around the rotating shaft 121, overcoming the torque of the torsion spring 124 and moving the collection tube 125 out of the working area. After the dispensing is completed, the electric push rod 222 rises and resets. The first toothed plate 230 drives the positioning plate 280 away from the PCB board through the reverse transmission of the gear 243 and the second toothed plate 244. At the same time, the torsion spring 124 releases its stored energy to drive the L-shaped rotating plate 122 to reset, so that the collection tube 125 and the collection cylinder 126 are re-aligned with the dispensing port to receive the excess glue and prevent excess glue from dripping onto the PCB board and the conveyor body 110.

[0040] It should be noted that the specific models and specifications of the conveyor body 110, electric push rod 222 and dispensing machine body 292 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0041] The power supply and operating principle of the conveyor body 110, the electric push rod 222 and the dispensing machine body 292 are clear to those skilled in the art and will not be described in detail here.

[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
