[0042] This invention provides an automatic writing board assembly device, including a frame 10. Two parallel slide rails 11 are provided above the frame 10. The slide rails 11 are supported by several folded edge blocks. Each slide rail 11 has a sliding groove 513, which is arranged facing each other. The sliding grooves 513 are used to place the writing board and limit the movement direction of the writing board. Figure 1As shown, the chute 513 is only connected to one side of the slide rail 11, and the writing board flows out of the device from the connected side. A feeding mechanism 20 is provided at the front end of the slide rail 11. The feeding mechanism 20 is formed by several straight strips wrapped around each other, with a raw material cavity formed in the middle. The writing board is placed in the raw material cavity. The bottom of the feeding mechanism 20 is connected to the chute 513, allowing the writing board to continuously enter the chute 513 from the raw material cavity, thus facilitating subsequent transfer. A feeding mechanism 30 is provided between the slide rails 11, which drives the writing board to move forward; the switch feeding mechanism 41 includes a vibratory feeder, on which a conveyor is connected, and the switch components arranged by the vibratory feeder are output through the conveyor; a switch mounting mechanism 42 is fixed on the frame 10, including a movable gripper 424, which is located above the conveyor and transfers the switch from the conveyor to the writing board by gripping it; because the switch is placed The position of the switch after being placed in the slot of the writing board is not fixed. To facilitate subsequent processing, this equipment also includes a switch positioning mechanism 43, which is fixed to the slide rail 11. The switch is pulled to one side of the writing board through the switch positioning mechanism 43. As shown in the figure, the switch is pulled to the left side of the writing board in this equipment. The circuit board is a whole piece when it leaves the factory. Before installation, the whole circuit board needs to be broken into individual circuit boards. Therefore, this equipment includes a circuit board breaking mechanism 51, which is fixed to the frame 10. A circuit board transfer mechanism 52 is provided above the circuit board breaking mechanism 51. The circuit board transfer mechanism 52 is used to transfer individual circuit boards to the writing board. At the same time, this equipment also includes a screw-driving mechanism 60 for installing screws onto the circuit board and fixing the circuit board to the writing board with screws. Finally, a dust removal mechanism 70 is provided at the end of the slide rail 11 for cleaning debris from the surface of the writing board.

[0043] The specific operation process of this equipment is as follows: The writing board is first placed in the unloading mechanism 20, and the writing board is continuously moved to the subsequent workstation by the feeding mechanism 30. The first step is to install the switch on the writing board and align the switch to ensure that the switch is located on the leftmost side of the slot in the writing board. Then, the circuit board is broken into pieces and transferred to the writing board. Then, the screw-driving mechanism 60 is used to drive screws into the circuit board. After the screws are driven, the writing board moves to the bottom of the dust removal mechanism 70. The dust removal mechanism 70 removes dust and other debris from the surface of the writing board.

[0044] The feeding mechanism 30 includes a drive module 31, the drive module 31 as follows: Figure 6As shown, it includes a housing, a motor fixed to the housing, a lead screw connected to the motor's output shaft, and a lead screw nut fitted on the lead screw. A control box 32 is slidably connected to the drive module 31. The sliding of the control box 32 is driven by the lead screw nut. To achieve the effect of moving the writing tablet, a control motor 321 is provided on the side of the control box 32. A sliding plate 322 is slidably connected to the bottom surface of the control box 32. A rack 323 is fixed on the sliding plate. Several rotating shafts 324 are rotatably connected to the control box 32. Several transfer claws 325 and gears 326 are fixed on the rotating shafts 324. The gears 326 mesh with the rack 323. When the control motor 321 drives the rack 323 to move, the rack 323 drives the gears 326 to rotate, which in turn drives the rotating shafts 324 to rotate, thereby controlling the rotation of the transfer claws 325. Figure 3 As shown, the transfer claw 325 can change its position during rotation, either above or below the slide groove 513, thereby achieving the effect of the transfer claw 325 driving the writing board to move. The reciprocating motion of the control box 32 can be controlled by the drive module 31, thereby achieving the effect of continuously pushing the writing board forward.

[0045] The switch mounting mechanism 42 in this device includes a base plate 421 fixed to the frame 10. A vertical sliding seat 422 is slidably connected to the base plate 421. The vertical sliding seat 422 can move up and down along a pre-set guide rail on the base plate 421. A horizontal sliding seat 423 is slidably connected to the vertical sliding seat 422. The horizontal sliding seat 423 is elongated. A gripper 424 is slidably connected to the horizontal sliding seat 423. The gripper 424 first picks up the switch from the conveyor channel, raises the gripper 424 through the vertical sliding seat 422, and then moves the gripper 424 to above the writing board through the horizontal sliding seat 423. Then, the vertical sliding seat 422 is controlled to lower the gripper 424, thereby placing the switch in the writing board.

[0046] To achieve the correct positioning of the switch, allowing it to be located on the far left of the slot in the writing board for easier subsequent processing, the specific switch positioning mechanism 43 in this device includes a positioning fixing seat 431, a positioning moving seat 432, and an arc-shaped clamping plate 433, as shown below. Figure 5As shown, the positioning fixing seat 431 is fixed to the slide rail 11, and the positioning moving seat 432 is slidably connected to the slide rail 11. A positioning cylinder 434 is connected between the positioning fixing seat 431 and the positioning moving seat 432. The positioning cylinder 434 pulls the positioning moving seat 432 to slide. A clamping cylinder 435 is fixed to one side of the positioning moving seat 432. The end of the arc-shaped clamping plate 433 is rotatably connected to the clamping cylinder 435 to increase the freedom of the arc-shaped clamping plate 433. The positioning moving seat 432 is rotatably connected to a rotating block 436. The middle part of the arc-shaped pressing plate 433 is rotatably connected to the rotating block 436. When the pressing cylinder 435 pushes upward, with the rotating block 436 as the rotation center, the free end of the arc-shaped pressing plate 433 moves downward, thereby bringing the end of the arc-shaped pressing plate 433 into contact with the switch. After pressing, the positioning cylinder 434 pulls the entire arc-shaped pressing plate 433 to one side, thereby pulling the switch to one side and achieving the positioning effect of the switch.

[0047] To disassemble a single circuit board, this device includes a circuit board breaking mechanism 51, specifically comprising a folding edge fixing seat 511. A sliding fixing platform 512 is provided on the bottom surface of the folding edge fixing seat 511. A sliding groove 513 is provided on the sliding fixing platform 512, and a folding edge rack 514323 is slidably connected within the sliding groove 513. A folding edge driving cylinder 515 is provided between the folding edge fixing seat 511 and the folding edge rack 514323. The folding edge driving cylinder 515 controls the sliding of the folding edge rack 514323. Figure 9 As shown, the folding fixing seat 511 is also provided with a vertical platform. The end of the folding driving cylinder 515 is rotatably connected to the vertical platform, so that the folding driving cylinder 515 and the slide groove 513 are as close as possible to the same horizontal plane. A guide boss 516 is provided on one side of the sliding fixing platform 512, and several guide posts 517 are provided on the side of the guide boss 516, such as... Figure 9 As shown, the guide posts 517 are arranged in an arc shape, and an arc-shaped folding block 518 is engaged on the folding rack 514323. An arc-shaped guide groove 519 is provided in the arc-shaped folding block, and the guide posts 517 are located in the arc-shaped guide groove 519. The arc-shaped folding block can rotate along the guide posts 517 and is driven by the engagement of the folding rack 514323. When the end of the arc-shaped folding block is lifted upward, the circuit board can be broken off from the whole piece. Therefore, it is best to provide a baffle above the end of the arc-shaped folding block that performs the breaking action, so as to better cooperate with the arc-shaped folding block to perform the breaking operation.

[0048] Before and after disassembly, the circuit board needs to be transferred. Therefore, the circuit board transfer mechanism 52 includes two transfer fixing seats 521, with a placement cavity 522 formed between the two transfer fixing seats. The folding edge fixing seat 511 is fixed in the placement cavity 522. Two spaced conveyor belts 523 are provided between the transfer fixing seats. The conveyor belts 523 are used to transfer the circuit board. The two conveyor belts 523 are independent entities, and there is a gap between them. The arc-shaped folding edge block 518 is provided between the two conveyor belts 523. One of the transfer fixing seats is provided with a pusher strip 524, such as... Figure 1 As shown, a cylinder is externally connected to the push bar 524. The cylinder pushes the broken circuit board to move. A circuit board transfer guide rail 525 is fixed on another moving seat. A circuit board lifting cylinder 526 is slidably connected to the circuit board transfer guide rail 525. The end of the circuit board lifting cylinder 526 is provided with an adsorption claw 527. The circuit board lifting cylinder 526 controls the up and down movement of the adsorption claw 527. After the circuit board is gripped, the circuit board lifting cylinder 526 moves along the circuit board transfer guide rail 525. As shown in the figure, there is a grooved protrusion on the conveyor belt 523 where the broken circuit board is located. The broken circuit board enters the groove, which serves as a limit. When the conveyor belt 523 is running, the circuit board is always located on one side of the groove, which facilitates the adsorption claw 527 to adsorb it.

[0049] Considering the thinness of the circuit board, which makes it susceptible to damage during screw driving, this device provides a screw driving mechanism 60 with elastic buffering performance. The screw driving mechanism 60 includes a main support plate 61, which is fixed to the frame 10. A transverse block 62 is slidably connected to the top of the main support plate 61. A guide rail can be installed below the transverse block 62 to assist sliding. A secondary support plate 63 is fixed to the transverse block 62. A drive motor 64 is slidably connected to the secondary support plate 63. A stroke adjusting cylinder 631 is fixed to the secondary support plate 63. A spring 65 guide shaft 632 is fixed to the end of the stroke adjusting cylinder. A spring 65 guide sleeve 633 is slidably connected to the outside of the spring 65 guide shaft 632. 2. The spring 65 guide sleeve 633 can slide along the spring 65 guide sleeve 633, while ensuring that the spring 65 guide shaft 632 will not detach from the spring 65 guide sleeve 633. Therefore, an annular fixing sleeve is provided at the end of the spring 65 guide sleeve 633. A motor connecting block 641 is sleeved on the spring 65 guide sleeve 633. The drive motor 64 is fixedly connected to the motor connecting block 641. Springs 65 are respectively provided on the spring 65 guide shaft 632 and the spring 65 guide sleeve 633. A vacuum suction head 66 with a central hole 661 is slidably connected to the secondary support plate 63. An automatic screw feeding device is externally connected to the vacuum suction head 66. The screw prepared by the external device enters the central hole 661 of the vacuum suction head 66. The vacuum suction head 66 and the... The spring 65 guide sleeve 633 is fixedly connected, preferably at the lower end of the spring 65 guide sleeve 633. A screwdriver 642 is connected to the drive motor 64, and the screwdriver 642 is located in the intermediate hole 661. The screwdriver 642 has the same shape as a traditional screwdriver and is mainly used to tighten the screws in the intermediate hole 661. For ease of description, the spring 65 guide shaft 632 and the spring 65 on the spring 65 guide sleeve 633 are respectively referred to as the first spring 65 and the second spring 65. When the device is in operation, the stroke adjusting cylinder 631 pushes downwards. At this time, the first spring 65 is compressed, thereby pushing the motor connecting block 641 to descend synchronously. Then, the second spring 65 pushes the vacuum suction head 66 to descend. The first spring 65 absorbs the initial vibration of the stroke adjustment cylinder 631. A stop is provided at the bottom of the secondary support plate 63. After the vacuum suction head 66 moves downward, it stops descending after contacting the stop. At this time, there is a certain distance between the outlet of the vacuum suction head 66 and the circuit board. Then, the stroke adjustment cylinder 631 continues to push downward. At this time, the first and second springs 65 continue to compress. The motor connecting block 641 and the drive motor 64 also move downward synchronously. The screwdriver 642 moves into the intermediate hole 661 until it contacts the screw. Then, the screwdriver 642 pushes the screw onto the circuit board, and then the screwing operation on the circuit board is performed. This equipment gradually absorbs the vibration during operation through the first and second springs 65.This prevents the screwdriver 642 from descending too quickly during screw-driving and damaging the circuit board.

[0050] The slide rail 11 has station plates 71 on both sides, and the top of the station plate 71 is higher than the slide rail 11. The dust removal mechanism 70 includes a dust suction box 72. The top of the station plate 71 is provided with a cleaning moving rail 73. The dust suction box 72 is slidably connected to the cleaning moving rail 73. The dust suction box 72 is connected to a dust discharge pipe 74. The dust suction box 72 can move along the cleaning moving rail 73 to absorb the dust or other debris remaining on the surface of the writing board during the processing. After the dust removal is completed, the installation of the outer frame of the writing board is completed.
