Description

Technical Field

[0001] This utility model belongs to the technical field of circuit board conveying devices, and particularly relates to a multi-station conveying device for dispensing circuit boards. Background Technology

[0002] Circuit board dispensing involves applying functional adhesives such as epoxy resin, silicone, and conductive adhesives with micron-level precision to designated locations on circuit board pads and component leads. This achieves functions such as stable bonding of components, moisture-proof sealing, and electrical connection protection. In modern electronic products, with their trend towards miniaturization and integration, the precision and efficiency of the dispensing process directly impact product quality and production efficiency. In current production models, circuit boards are typically fixed to the dispensing station manually. After dispensing, the circuit board must be manually removed and replaced with a new one. This manual loading and unloading process disrupts the dispensing operation, preventing continuous operation and resulting in low production efficiency. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a multi-station conveying device for dispensing circuit boards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Both movable plates are provided with multiple sets of fixing components; each set of fixing components includes a first fixing plate and a second fixing plate;

[0008] The first fixed plate is fixedly disposed on the top of the moving plate and is uniformly arranged in a linear array along the conveying direction of the moving plate;

[0009] The second fixed plate is slidably disposed on the top of the movable plate and is disposed on one side of the corresponding first fixed plate;

[0010] The movable plate is provided with a first sliding groove; a first slider is slidably disposed in the first sliding groove, and the first slider is connected to the bottom of the second fixed plate.

[0011] The bottom of the movable plate is provided with a movable component, which is connected to the first slider and drives the first slider to slide within the first groove;

[0012] The first support is equipped with a conveying assembly for driving the moving plate to slide within the first moving groove;

[0013] The second bracket is located on one side of the first bracket, and the second bracket is equipped with a dispensing assembly;

[0014] The first bracket is equipped with a pressing component, which is located below the dispensing component and is used to press down and fix the two ends of the circuit board.

[0015] The above technical solution involves setting up two movable plates. While dispensing adhesive on the circuit board on one movable plate, the other movable plate can fix the circuit board in place. By alternating the movement of the two movable plates, the dispensing operation on the circuit board can be carried out continuously. The circuit board is placed between the first and second fixed plates, and the circuit board is clamped by the movement of the second fixed plate. When the movable plate moves to the working area, the pressing component presses down on both sides of the circuit board to prevent longitudinal movement of the circuit board during the dispensing process from affecting the dispensing effect.

[0016] Furthermore, each of the fixing components has guide plates at both ends of the opposite side of the first fixing plate and the second fixing plate, and the opposite side of the two guide plates is inclined.

[0017] With the above technical solution, when the second fixed plate moves, the guide plate can center-align the two outer sides of the circuit board, thereby aligning the centerline positions of all circuit boards.

[0018] Furthermore, the moving component includes a scissor-type telescopic frame, which includes a plurality of first links and second links. The middle of the first links and the second links are rotatably connected by a pin, and the two ends of the first link are rotatably connected to the ends of the adjacent second links by pins.

[0019] The first slider is connected to the corresponding first link and is located at the intersection of the first link and the second link;

[0020] The bottom of the movable plate is equipped with a first electric telescopic rod;

[0021] The output end of the first electric telescopic rod is connected to the second link at the end of the scissor telescopic frame, and the connection end is at the intersection of the corresponding first link and the second link.

[0022] Through the above technical solution, the extension and retraction of the first electric telescopic rod are controlled to extend and retract the corresponding first and second connecting rods, thereby realizing the extension and retraction of the scissor telescopic frame and thus realizing the movement of the first slider within the first slide groove.

[0023] Furthermore, a second moving groove is provided at the bottom of the first moving groove;

[0024] The conveying assembly includes a threaded rod; the threaded rod is rotatably disposed within a second movable groove;

[0027] One of the first brackets is equipped with a motor, and the output end of the motor is connected to a transmission wheel.

[0028] Through the above technical solution, the motor drives the transmission wheel connection, and drives another transmission wheel connection through the transmission belt, so that the two threaded rods rotate synchronously, and the first moving block drives the moving plate to move in the first moving groove.

[0029] Furthermore, the pressing assembly includes a moving rod and multiple pressing rods;

[0030] The first bracket is provided with a third movable slot, and a second electric telescopic rod is provided in the third movable slot;

[0031] One end of the movable rod is slidably disposed in the third movable groove, and the movable rod is connected to the second electric telescopic rod;

[0032] The other end of the moving rod extends out of the third moving slot and is rotatably connected to one of the pressure rods; and the pressure rod is rotatably disposed in the mounting base, which is located on the top of the first bracket;

[0033] The pressure rods are connected by a fixing rod;

[0034] The pressure bar is folded.

[0035] Furthermore, the end of the pressure rod away from the mounting base is arc-shaped, and the arc-shaped end is provided with a rubber layer.

[0036] Through the above technical solution, the second electric telescopic rod extends and drives the moving rod to move in the third moving groove, thereby driving the pressure rod to move upward and rotate on the mounting base, so that the arc-shaped end of the pressure rod moves downward to press against the end of the circuit board, and the rubber layer can protect the circuit board.

[0037] Furthermore, a fourth moving slot is provided at the top of each of the two first moving slots;

[0038] One of the fourth movable slots is located at the left end of the first bracket;

[0039] Another fourth movable slot is opened at the right end of another first bracket;

[0042] The fourth moving slot is provided with a sensing block on the side near the dispensing assembly;

[0043] The sensing block is electrically connected to the second electric telescopic rod and the motor.

[0044] With the above technical solution, when the moving plate moves to the dispensing area, the sensing block of the corresponding second moving block comes into contact with the sensing block of the fourth moving slot, and a signal is transmitted to the motor to stop rotating. At the same time, the second electric telescopic rod starts to move, so that the pressure rod presses down to fix the circuit board.

[0045] This utility model has the following beneficial effects:

[0046] 1. Two movable plates are set up. While the dispensing work is being carried out on the circuit board on one movable plate, the other movable plate is used to fix the circuit board.

[0047] 2. The circuit board is placed between the first and second fixing plates. The circuit board is clamped by the movement of the second fixing plate, and the guide plate is also aligned to the center from the other two sides. When the moving plate moves to the working area, the pressing component presses down on both sides of the circuit board to avoid the circuit board moving longitudinally during the dispensing process and affecting the dispensing effect.

By alternating the movement of the two moving plates 3, the dispensing operation of the circuit board 8 can be carried out continuously, and the circuit board 8 is placed between the first fixing plate 31 and the second fixing plate 32. The circuit board 8 is clamped by the movement of the second fixing plate 32. When the moving plate 3 moves to the working area, the pressing component presses down on both sides of the circuit board 8 to avoid the longitudinal movement of the circuit board 8 during the dispensing process from affecting the dispensing effect.

[0066] Furthermore, the moving component includes a scissor-type telescopic frame, which includes multiple first links 41 and second links 42. The first links 41 and second links 42 are rotatably connected at the middle by a pin, and the two ends of the first link 41 are rotatably connected to the ends of the adjacent second links 42 by pins.

When the second electric telescopic rod 62 extends, it drives the moving rod 6 to move in the third moving groove 13, thereby driving the pressing rod 61 to move upward and drive the pressing rod 61 to rotate on the mounting base 63, thereby causing the arc-shaped end of the pressing rod 61 to move downward and press against the end of the circuit board 8. The rubber layer can protect the circuit board 8.

[0069] Furthermore, each of the two first moving slots 11 is provided with a fourth moving slot 14 at its top; one of the fourth moving slots 14 is located at the left end of the first bracket 1; the other fourth moving slot 14 is located at the right end of the other first bracket 1; a second moving block 36 is slidably provided in the fourth moving slot 14, and the second moving block 36 is connected to the corresponding moving plate 3; a sensing block is provided on the side of the second moving block 36 near the dispensing assembly 7; a sensing block is provided on the side of the fourth moving slot 14 near the dispensing assembly 7; the sensing block is electrically connected to the second electric telescopic rod 62 and the motor 54.

[0070] The working principle of this utility model is as follows: First, the circuit board 8 is placed on the movable plate 3, between the first fixed plate 31 and the second fixed plate 32. The first electric telescopic rod 4 drives the scissor-type telescopic frame to shorten, thereby moving the second fixed plate 32 toward the corresponding first fixed plate 31 to clamp the circuit board 8 on both sides. During the movement of the second fixed plate 32, the guide plate 35 can center the circuit board 8 from the other two sides. After the circuit board 8 is fixed, the motor 54 drives the transmission wheel 52 to rotate, which in turn drives another transmission wheel 52 to rotate via a rotating belt, thereby driving the two threaded rods 5 to rotate. The first movable block 51 moves the movable plate 3 to the dispensing area. When the movable plate 3 moves to the designated area, the sensing block on the second movable block 36 contacts the sensing block on the fourth movable slot 14. At this time, through Signal transmission stops the motor 54 from rotating. At the same time, the second electric telescopic rod 62 pushes the moving rod 6 to move, so that the pressure rod 61 presses and fixes the top of both ends of the circuit board 8. At this time, the dispensing assembly 7 moves down under the action of the corresponding drive mechanism and moves according to relevant instructions to dispense glue. During the dispensing process, the circuit board 8 is placed in another moving plate 3 and fixed. After the dispensing is completed, the motor 54 drives the threaded rod 5 to rotate in the opposite direction, so that the moving plate 3 that has completed the dispensing operation moves out of the work area. Another moving plate 3 enters the work area and moves to the accurate working area through the contact of the sensing block in another fourth moving slot 14. At this time, the dispensing operation is performed on the moving plate 3. The operator can replace the circuit board 8 on the other moving plate 3, thereby realizing the continuous dispensing operation.
