[0031] See Figures 1-12 This utility model provides a PCB board separating and loading machine, including a separating assembly 2 and a conveyor line connected to the separating assembly 2. The separating assembly 2 includes a conveyor belt 2-1, a first guide post 2-2, a lifting platform 2-5, a pusher cylinder 2-6, and a pusher plate 2-10. The first guide post 2-2 consists of multiple guide posts 1-2 arranged horizontally. The conveyor belt 2-1 is a double-row conveyor belt, including a left conveyor belt and a right conveyor belt, and the conveyor belt 2-1 is perpendicular to the direction of the first guide post 2-2. The lifting platform 2-5 is located in the middle of the left and right conveyor belts. 2-5 includes a bottom lifting cylinder and a platform connected to the lifting cylinder; the push plate 2-10 is a double-sided push plate, including a left push plate and a right push plate; the push plate cylinder 2-6 is a double-sided push plate cylinder, including a left push plate cylinder and a right push plate cylinder; a left push plate is provided on the upper left side of the left conveyor belt, the left side of the left push plate is connected to the left push plate cylinder, and the left push plate cylinder can push the left push plate to the right and reset; a right push plate is provided on the upper right side of the right conveyor belt, the right side of the right push plate is connected to the right push plate cylinder, and the right push plate cylinder can push the right push plate to the left and reset.

[0032] For situations where individual boards need to be inserted into a material frame, this invention separates the boards after they are stacked, eliminating the need to insert them into a material frame and improving production efficiency.

[0033] In a preferred embodiment of this utility model, the partition assembly 2 further includes a fixed platform 2-11 and partition clips; the fixed platform 2-11 includes a left fixed platform and a right fixed platform; the partition clips include a left partition clip and a right partition clip; the left partition clip is fixed to the top of the left fixed platform, and lifting components are provided on the front and rear sides of the left partition clip, so that there is a gap between the bottom of the left partition clip and the left fixed platform; the starting position of the left push plate is located at the gap between the left partition clip and the left fixed platform, and the left push plate can move to the right relative to the left fixed platform under the push of the left push plate cylinder; the right partition clip is fixed to the top of the right fixed platform, and lifting components are provided on the front and rear sides of the right partition clip, so that there is a gap between the bottom of the right partition clip and the right fixed platform; the starting position of the right push plate is located at the gap between the right partition clip and the right fixed platform, and the right push plate can move to the left relative to the right fixed platform under the push of the right push plate cylinder.

[0034] Because the front and rear sides of the board splitter are equipped with lifting components, there is a gap between the bottom of the board splitter and the fixed platform 2-11; therefore, the pusher plate 2-10 can pass through the gap to push the PCB light board 3 and make it fall onto the conveyor belt 2-1.

[0035] Specifically, the starting position of the left push plate is set at the left end of the gap between the left split plate clamp and the left fixed platform; the starting position of the right push plate is set at the right end of the gap between the right split plate clamp and the right fixed platform.

[0036] See Figure 6 As can be seen, the PCB bare board 3 is pushed out by the pusher plate 2-10 and falls onto the conveyor belt 2-1.

[0037] See Figure 7 As can be seen, both sides of the PCB board 3 are pushed out by the pusher plate 2-10 and fall onto the conveyor belt 2-1.

[0038] Specifically, the left conveyor belt is fixed to the right side of the left fixed platform, and the right conveyor belt is fixed to the left side of the right fixed platform.

[0039] Specifically, see Figure 8 The lifting and connecting conveyor line 1 includes a cylinder 1-1, a first linear slide rail assembly, a second linear slide rail assembly, a second guide column 1-2, a pusher plate assembly 1-3, a right conveyor belt 1-4, and a left conveyor belt 1-5. See the three-dimensional structural diagram of the pusher plate assembly 1-3. Figure 9 Their positional relationship is relatively Figure 8 It was flipped 180°.

[0040] Specifically, the conveyor line is also equipped with a support frame, with a fixed plate on top of the support frame and a cylinder 1-1 above the fixed plate; the conveyor line is also equipped with a fixed frame, which consists of upper and lower layers of plates and four support columns; the cylinder 1-1 passes through the fixed plate and connects to the fixed frame, thereby controlling the fixed frame to move up and down; the bottom of the support frame is equipped with a double-row parallel first linear slide rail assembly, on which a conveyor belt perpendicular to the linear slide rail assembly is mounted, including a left conveyor belt 1-5 and a right conveyor belt 1-4; the positions of the left conveyor belt 1-5 and the right conveyor belt 1-4 can be adjusted on the first linear slide rail assembly to correspond to the position of the conveyor belt 2-1; the first linear slide rail assembly is equipped with a locking block to lock the position of the conveyor belt.

[0041] Specifically, a double-row parallel second linear slide rail assembly is provided below the fixed plate. The push plate assembly 1-3 is fixed on the second linear slide rail assembly. The position of the push plate assembly 1-3 can be adjusted on the second linear slide rail assembly to correspond to the position of the PCB light board 3 that needs to be pushed. A locking block is provided on the second linear slide rail assembly to lock the position of the push plate assembly 1-3.

[0042] The reason for needing pusher assembly 1-3 is that there is a gap in the middle of the conveyor line used in conjunction with the subsequent connecting line, which cannot convey the material into place. Pusher assembly 1-3 is needed to push it in.

[0043] The first linear guide rail assembly allows the left and right conveyor belts 1-4 to be adjusted to any position to match the track and product they are connected to.

[0044] Specifically, the board separation assembly 2 also includes a first sensor 2-8 and a second sensor 2-9. The first sensor 2-8 is located at the front end of the fixed platform 2-11 and is used to sense the PCB board 3 falling into the conveyor belt 2-1. The second sensor 2-9 is located at the end of the fixed platform 2-11 and is used to sense the PCB board 3 after it has been conveyed by the conveyor belt 2-1 and is ready to enter the conveyor belt.

[0045] When the PCB blank 3 is conveyed above the second sensor 2-9, the second sensor 2-9 senses the object and the conveyor belt 2-1 stops, waiting for the cylinder 1-1 to control the fixed frame to move upward until the horizontal plane of the conveyor belt and the conveyor belt 2-1 are level. Then the conveyor belt and the conveyor belt 2-1 start, and the PCB blank 3 is conveyed from the conveyor belt 2-1 to the conveyor belt.

[0046] Specifically, the plate-separating loading machine also includes a movable table, on which the plate-separating assembly 2 is mounted.

[0047] This setup can be configured using a modular structure to suit production line requirements, and can be removed when not needed for easy mobile operations.

[0048] Specifically, the slitting assembly 2 also includes a green start button 2-3, a red stop button 2-4, and a barcode scanner 2-7. The green start button 2-3 and the red stop button 2-4 are located on the table surface of the movable platform; the barcode scanner 2-7 is located at the connection between the slitting assembly 2 and the conveyor line.

[0049] The operation process of this PCB bare board separation and loading machine is as follows:

[0050] 1. Press the green start button 2-3;

[0051] 2. See Figure 5 Place the bare PCB board 3 into the area shown.

[0052] 3. See also Figure 6 , Figure 6 The diagram shows the result after push-board 2-10 on one side; the left and right push-boards are pushed separately to separate the boards. Due to the setting of the board separation card, push-board 2-10 will only push out one bare PCB board 3 at a time.

[0053] 4. The bare PCB board 3 falls onto the lifting platform 2-5;

[0054] 5. See also Figure 7 , Figure 7 The diagram shows the bare PCB board 3 falling onto the conveyor belt 2-1; the lifting platform 2-5 descends, and the bare PCB board 3 falls onto the conveyor belt 2-1;

[0055] 6. The first sensor 2-8 detects that the PCB board 3 has fallen into the conveyor belt 2-1, and the conveyor belt 2-1 starts to transport the board; 7. The second sensor 2-9 detects that the PCB board 3 has been transported by the conveyor belt 2-1 and stops the conveyor belt 2-1; 8. At this time, the cylinder 1-1 controls the fixed frame to move upward. When the fixed frame rises to the set position so that the position of the conveyor belt corresponds to that of the conveyor belt, the rising stops.

[0056] 9. The conveyor belt begins transporting PCB board 3. After transport is complete, the status at this point is as follows: Figure 10 ;

[0057] 10. Cylinder 1-1 controls the fixing bracket to move downward; at this time, steps 2-8 can be performed simultaneously;

[0058] 11. When the fixed frame moves down to the set position, the conveyor belt transports the PCB board 3 to its limit position. The pusher assembly 1-3 pushes the product to the required position and then returns to its original position. See the status diagram below. Figure 11 and Figure 12 12. Cylinder 1-1 controls the fixing bracket to move to the set position, and repeats steps 8-11.

[0059] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
