[0021] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an automatic panel assembly machine 10 includes: a worktable 100, a placement fixture 400, a suction cup mechanism 500, and a first conveying mechanism 600. A first material bin 200 and a second material bin 300 are spaced apart on the worktable 100. The placement fixture 400 is mounted on the worktable 100. The suction cup mechanism 500 includes: a frame 510, a first slide rail 520, a second slide rail 530, a suction cup assembly 550, and two third slide rails 540. The frame 510 is mounted on the worktable 100. The two third slide rails 540 are spaced apart on the frame 510. The second slide rail 530 is slidably mounted on the two third slide rails 540. The first slide rail 520 is slidably mounted on the second slide rail 530. The suction cup assembly 550 includes: a mounting bracket... The mounting bracket 551, a plurality of first suction cups 552, and a plurality of second suction cups 553 are provided. The first end of the mounting bracket 551 is slidably mounted on the first slide rail 520. Each first suction cup 552 and each second suction cup 553 are respectively arranged around the second end of the mounting bracket 551, and each first suction cup 552 is located outside the second suction cup 553. The sliding direction of the mounting bracket 551 on the first slide rail 520, the sliding direction of the first slide rail 520 on the second slide rail 530, and the sliding direction of the second slide rail 530 on the two third slide rails 540 are arranged perpendicular to each other. The first conveying mechanism 600 is mounted on the worktable 100 and is located at the first end of the placement fixture 400.

[0022] In this embodiment, a first hopper 200 and a second hopper 300 are spaced apart on the workbench 100. The first hopper 200 is used to place spring fixtures, and the second hopper 300 is used to place circuit boards. A fixture 400 is placed on the workbench 100 to hold and fix the spring fixtures. The first slide rail 520, the second slide rail 530, the two third slide rails 540, and the mounting bracket 551 of the suction cup assembly 550 form a three-axis moving structure on the frame 510, which can drive each first suction cup 552 and each second suction cup 553 on the mounting bracket 551 to move in the three-axis direction. That is, by sliding the second slide rail 530 on the two third slide rails 540, the first suction cup 552 and each second suction cup 553 are driven to move in the X-axis direction. The slide rail 520 slides on the second slide rail 530 to drive the first suction cups 552 and the second suction cups 553 to move in the Y-axis direction. The mounting bracket 551 slides on the first slide rail 520 to drive the first suction cups 552 and the second suction cups 553 to move in the Z-axis direction. The first suction cups 552 and the second suction cups 553 are both vacuum suction cups. The first suction cup 552 is used to pick up the spring fixture and move it to place it on the placement fixture 400. The second suction cup 553 is used to pick up the circuit board and move it to clamp it on the spring fixture. This enables the automated clamping of the circuit board on the spring fixture. The spring fixture with the circuit board clamped can be transported to the subsequent circuit board processing equipment for processing through the first conveying mechanism 600, which greatly improves the board assembly efficiency and plays a role in reducing costs and increasing efficiency.

[0023] In this embodiment, when the circuit board is clamped onto the spring fixture, the first suction cup 552 moves in a three-axis direction to pick up the spring fixture from the first hopper 200 and moves it to place it on the placement fixture 400. The second suction cup 553 moves in a three-axis direction to pick up the circuit board from the second hopper 300 and moves it to clamp onto the spring fixture. Finally, the clamped spring fixture and circuit board are picked up as a whole by the first suction cup 552 and the second suction cup 553, and then moved to the first conveying mechanism 600, which transports them to the subsequent circuit board processing equipment for processing. It is worth noting that the methods of driving the mounting bracket 551 to slide on the first slide rail 520, driving the first slide rail 520 to slide on the second slide rail 530, and driving the second slide rail 530 to slide on the two third slide rails 540 are techniques that are known to those skilled in the art and are achievable. In this embodiment, they are not described in detail. For example, they can be achieved by the cooperation of a motor, a lead screw, and a lead screw nut.

[0024] In one embodiment, such as Figure 2As shown, the first hopper 200 includes: a first lifting guide rail 210, a first lifting plate 220 and two first side plates 230. The two first side plates 230 are spaced apart. Each first side plate 230 is provided with a first bottom limiting part 231 and two first side limiting parts 232, and forms a first placement cavity 201 at intervals. The first lifting guide rail 210 is located on one side of the two first side plates 230. The first lifting plate 220 is slidably disposed on the first lifting guide rail 210, and the first lifting plate 220 is movably located within the first placement cavity 201. Specifically, the workbench 100 has a receiving cavity, and the first hopper 200 is located in the receiving cavity. Two first side plates 230 are spaced apart at the bottom of the receiving cavity. The first bottom limiting part 231 and the two first side limiting parts 232 on the two first side plates 230 are arranged facing each other, which can form a first placement cavity 201 with a square cross-sectional area between the two first side plates 230. The spring fixture is placed in the first placement cavity 201. The first lifting guide rail 210 is set on the side wall of the receiving cavity. The first lifting plate 220 moves up and down on the first lifting guide rail 210 and abuts against the lowest spring fixture in the first placement cavity 201, thereby lifting each spring fixture in the first placement cavity 201, so that when the first suction cup 552 picks up the spring fixture, it can always maintain a constant height for picking up the material.

[0025] In one embodiment, such as Figure 2 As shown, the second hopper 300 includes: a second lifting guide rail 310, a second lifting plate 320, and two second side plates 330. The two second side plates 330 are spaced apart. Each second side plate 330 is provided with a second bottom limiting part 331 and two second side limiting parts 332, and forms a second placement cavity 301 at intervals. The second lifting guide rail 310 is located on one side of the two second side plates 330. The second lifting plate 320 is slidably disposed on the second lifting guide rail 310, and the second lifting plate 320 is movably located within the second placement cavity 301. Specifically, the second hopper 300 is located in the receiving cavity of the workbench 100. Two second side plates 330 are spaced apart at the bottom of the receiving cavity. The second bottom limiting part 331 and the two second side limiting parts 332 on the two second side plates 330 are arranged facing each other, which can form a second placement cavity 301 with a square cross-sectional area between the two second side plates 330. The circuit board is placed in the second placement cavity 301. The second lifting guide rail 310 is set on the side wall of the receiving cavity. The second lifting plate 320 moves up and down on the second lifting guide rail 310 and abuts against the bottommost circuit board in the second placement cavity 301, thereby lifting each circuit board in the second placement cavity 301, so that when the second suction cup 553 picks up the circuit board, it can always maintain a constant height for picking up the material.

[0026] It is worth noting that the methods of driving the first lifting plate 220 to move up and down on the first lifting guide rail 210 and driving the second lifting plate 320 to move up and down on the second lifting guide rail 310 are techniques that are known to those skilled in the art and are achievable. In this embodiment, they will not be described in detail. For example, they can be achieved by the cooperation of a motor, a lead screw and a lead screw nut.

[0027] In one embodiment, such as Figure 3 As shown, the placement fixture 400 includes a placement plate 410, a placement frame 420, and four corner limiting blocks 430. The placement plate 410 is disposed on the worktable 100, and the corner limiting blocks 430 are spaced apart on the placement plate 410. The placement frame 420 is fitted onto each of the corner limiting blocks 430. Specifically, the four corner limiting blocks 430 form square-shaped placement areas on the placement plate 410 at intervals. The placement frame 420 is stably fixed to the placement plate 410 by fitting onto each corner limiting block 430, that is, the inner sidewalls of the four corners of the placement frame 420 abut against the outer surfaces of the four corner limiting blocks 430, thereby stably placing the spring fixture on the placement frame 420.

[0028] In one embodiment, such as Figure 5 As shown, the first conveying mechanism 600 includes: two first guide rail plates 610, which are spaced apart on the workbench 100 and located at the first end of the placement fixture 400. Each first guide rail plate 610 is rotatably provided with two first pulleys 620, and a first conveyor belt 630 is rotatably wound around the two first pulleys 620. Each first guide rail plate 610 is provided with a first driver 640, which is drivenly connected to one of the first pulleys 620. Specifically, two first guide rail plates 610 are arranged opposite to each other on the workbench 100. A first conveyor belt 630 is rotatably arranged on the opposite side of the two first guide rail plates 610. That is, the first conveyor belt 630 is wound around two rotatably arranged first pulleys 620. A first driver 640 drives one of the first pulleys 620 to rotate, thereby driving the first conveyor belt 630 to move. The first driver 640 is a motor. Thus, the first conveying mechanism 600 can convey the spring fixture with the circuit board clamped by belt conveying.

[0029] In one embodiment, such as Figure 5As shown, the automatic panel assembly machine 10 further includes: a second conveying mechanism 700, the second conveying mechanism 700 having two second guide rail plates 710, the two second guide rail plates 710 being spaced apart on the worktable 100 and located at the second end of the placement fixture 400, each second guide rail plate 710 having two second pulleys 720 rotatably arranged at intervals, and a second conveyor belt 730 rotatably wrapped around the two second pulleys 720, each second guide rail plate 710 having a second driver 740, the second driver 740 being drivenly connected to one of the second pulleys 720. Specifically, by providing a second conveying mechanism 700, it can be used to connect to the wire-mounting board machine. The circuit board fed by the board-mounting board machine can be moved onto the second conveying mechanism 700. That is, the circuit board can be fed through the wire-mounting board machine and the second conveying mechanism 700. At this time, the second suction cup 553 picks up the circuit board on the second conveying mechanism 700. The first hopper 200 and the second hopper 300 or one of them is used for feeding spring fixtures. Two second guide rail plates 710 are arranged opposite to each other on the worktable 100. A second conveyor belt 730 is rotatably arranged on the opposite side of the two second guide rail plates 710. That is, the second conveyor belt 730 is wound around two rotatably arranged second pulleys 720. The second driver 740 drives one of the second pulleys 720 to rotate, thereby driving the second conveyor belt 730 to move. The second driver 740 is a motor. The second conveying mechanism 700 can transport the circuit board by belt conveying.

[0030] In one embodiment, the suction cup assembly 550 further includes a motor and a connecting frame. The motor is disposed on the second end of the mounting bracket 551 and is drivenly connected to the connecting frame. Each first suction cup 552 and each second suction cup 553 are respectively arranged around the connecting frame, and each first suction cup 552 is located outside each second suction cup 553. In this way, by driving the connecting frame to rotate by the motor, the first suction cup 552 and each second suction cup 553 on the connecting frame are rotated, which can better align with the spring fixture or circuit board, thereby better picking up the spring fixture or circuit board.

[0031] In one embodiment, such as Figure 2As shown, the first hopper 200 further includes two first adjusting rails 240, which are spaced apart on the worktable 100. Each first side plate 230 is slidably mounted on the two first adjusting rails 240, and the two first side plates 230 can move closer to or further away from each other. Specifically, by sliding the two first side plates 230 on the two first adjusting rails 240 respectively, and by moving the two first side plates 230 closer to or further away from each other, the distance between the two first side plates 230 can be adjusted to adjust the size of the first placement cavity 201. Thus, the first placement cavity 201 can be used to place spring fixtures of various specifications, realizing the stacking and feeding of spring fixtures of different specifications.

[0032] In one embodiment, such as Figure 2 As shown, the second hopper 300 further includes two second adjusting rails 340, which are spaced apart on the worktable 100. Each second side plate 330 is slidably mounted on the two second adjusting rails 340, and the two second side plates 330 can move closer to or further away from each other. Specifically, by sliding the two second side plates 330 onto the two second adjusting rails 340 respectively, and by moving the two second side plates 330 closer to or further away from each other, the distance between the two second side plates 330 can be adjusted to change the size of the second placement cavity 301. Thus, the second placement cavity 301 can be used to place circuit boards of various specifications, enabling the stacking and feeding of circuit boards of different specifications.

[0033] It is worth noting that the methods of driving the two first side plates 230 to move closer to or further away from each other and the two second side plates 330 to move closer to or further away from each other are techniques known to those skilled in the art and are achievable. In this embodiment, they will not be described in detail. For example, a lead screw can be rotatably provided at the bottom of the receiving cavity, with the external threads at both ends of the lead screw set in different helical directions. Two lead screw nuts with different internal helical directions are connected to the two first side plates 230 or the two second side plates 330 respectively. An adjusting handwheel is provided on one end of the lead screw or a motor is used to drive one end of the lead screw, so that the lead screw can be driven to rotate manually or by a motor.

[0034] In one embodiment, such as Figure 3As shown, the placement fixture 400 further includes: four horizontal guide rails 440 and four vertical guide rails 450. Each of the horizontal guide rails 440 is spaced apart on the placement plate 410. Each of the vertical guide rails 450 is slidably disposed on one of the horizontal guide rails 440. Each of the corner limiting blocks 430 is slidably disposed on one of the vertical guide rails 450. The sliding direction of the vertical guide rails 450 on the horizontal guide rails 440 and the sliding direction of the corner limiting blocks 430 on the vertical guide rails 450 are perpendicular to each other. Specifically, four horizontal guide rails 440 are distributed at the four corners of the placement area, four vertical guide rails 450 are set in pairs, and four corner limiting blocks 430 are set in pairs. When the two vertical guide rails 450 in each group slide on the horizontal guide rails 440, the two vertical guide rails 450 move towards each other or away from each other in the horizontal direction. When the two corner limiting blocks 430 in each group slide on the vertical guide rails 450, the two corner limiting blocks 430 move towards each other or away from each other in the vertical direction. This allows for adjustment of the size of the placement area and fixation of placement frames 420 of different specifications, thereby enabling fixation of spring fixtures of different specifications on the placement fixture 400.

[0035] In one embodiment, such as Figure 3 As shown, the placement fixture 400 further includes four positioning guide rails 460 and four side limiting blocks 470. The four positioning guide rails 460 are spaced apart on the placement plate 410 and located around the placement frame 420. Each side limiting block 470 is slidably disposed on one of the positioning guide rails 460. Each side limiting block 470 moves towards or away from the placement frame 420. When the spring fixture is placed on the placement frame 420, the side limiting block 470 moves towards the placement frame 420 and abuts against the outer edge of the spring fixture, which can further limit the position of the spring fixture on the placement frame 420, so that the spring fixture can be better placed on the placement frame 420. It is worth noting that the sliding of the vertical guide rail 450 on the horizontal guide rail 440, the sliding of the corner limiting block 430 on the vertical guide rail 450, and the sliding of the side limiting block 470 on the positioning guide rail 460 can be achieved by the cooperation of a motor, a lead screw, and a lead screw nut.

[0036] In one embodiment, such as Figure 5As shown, the first conveying mechanism 600 further includes two third adjusting rails 650, which are spaced apart on the worktable 100. Each first guide rail plate 610 is slidably mounted on one of the two third adjusting rails 650, and the two first guide rail plates 610 move towards or away from each other. Specifically, by sliding the two first guide rail plates 610 on the two third adjusting rails 650 respectively, and by allowing the two first guide rail plates 610 to move towards or away from each other, the distance between the two first guide rail plates 610 can be adjusted to change the track gauge of the first conveying mechanism 600. Therefore, the first conveying mechanism 600 can convey spring fixtures with circuit boards of various specifications.

[0037] In one embodiment, such as Figure 5 As shown, the second conveying mechanism 700 further includes two fourth adjusting rails 750, which are spaced apart on the worktable 100. Each second guide rail plate 710 is slidably mounted on one of the two fourth adjusting rails 750, and the two second guide rail plates 710 move towards or away from each other. Specifically, by sliding the two second guide rail plates 710 on the two fourth adjusting rails 750 respectively, and by moving them towards or away from each other, the distance between the two second guide rail plates 710 can be adjusted to change the track gauge of the second conveying mechanism 700. This allows the second conveying mechanism 700 to convey circuit boards of various specifications, enabling the loading of circuit boards of different specifications. It is worth noting that the movement of the two first guide rail plates 610 towards or away from each other and the movement of the two second guide rail plates 710 towards or away from each other can be achieved through the cooperation of a motor, a lead screw, and a lead screw nut.

[0038] Compared with the prior art, the present invention has at least the following advantages: The beneficial effects of this utility model are as follows: The automatic panel assembly machine provided by this utility model has a first hopper and a second hopper spaced apart on the worktable for placing spring fixtures and circuit boards respectively. The placement fixtures are placed on the worktable. The first slide rail, the second slide rail, the two third slide rails, and the mounting frame of the suction cup assembly form a three-axis moving structure on the frame, which can drive the first suction cups and the second suction cups on the mounting frame to move in three-axis directions. The first suction cup is used to pick up the spring fixtures and move them to place them on the placement fixtures. The second suction cup is used to pick up the circuit boards and move them to clamp them on the spring fixtures. This can realize the automation of clamping the circuit boards on the spring fixtures. The spring fixtures with the circuit boards clamped can be transported to the subsequent circuit board processing equipment for processing through the first conveying mechanism, which greatly improves the panel assembly efficiency and plays a role in reducing costs and increasing efficiency.
