Description

Technical Field

[0001] This invention belongs to the technical field of water pump production equipment, specifically relating to an integrated production line and production process for testing and pressing of automotive electronic water pump assembly. Background Technology

[0002] The assembly process of an automotive electronic water pump requires first inspecting the PCB board and pump body for qualification. The PCB board then needs to be pressed into a PCB board inspection platform for testing. Traditionally, a suction cup is used to directly place the PCB board into the PCB board inspection slot on the platform. However, this method has several drawbacks. First, to protect the suction cup, it prevents the PCB board from being fully pressed into the inspection slot, thus affecting the inspection results as the PCB board cannot make complete contact with the various PCB board inspection contacts within the slot. Second, releasing the suction cup causes the PCB board to tilt, preventing it from fitting properly into the inspection slot and thus hindering its entry for testing. Finally, after the PCB board has been pressed into the inspection slot and completed the inspection, it needs to be ejected from the slot.

[0003] Therefore, there is an urgent need to develop a new integrated production line and process for testing and pressing of automotive electronic water pumps to solve the above problems. Summary of the Invention

[0041] Example 1

[0042] In this embodiment, as Figures 1 to 12 As shown, this embodiment provides an integrated production line for testing and pressing of automotive electronic water pumps, comprising: a workpiece conveying device 1, a workpiece clamping device 2, a PCB board testing platform 3, a pump body testing platform 4, a PCB board positioning device 5, a pump body testing device 6, a pressing device 7, and a welding device 8; wherein the PCB board testing platform 3 and the pump body testing platform 4 are located on one side of the workpiece conveying device 1, the workpiece clamping device 2 is movably disposed above the workpiece conveying device 1, the PCB board testing platform 3, and the pump body testing platform 4, the PCB board positioning device 5 is movably disposed above the PCB board testing platform 3, the pump body testing device 6 is movably disposed above the pump body testing platform 4, the pressing device 7 is movably disposed above the pump body testing platform 4, and the welding device 8 is movably disposed above the workpiece conveying device 1; the workpiece clamping device 1... The holding device 2 places the PCB board and pump body conveyed on the workpiece conveying device 1 into the PCB board detection platform 3 and the pump body detection platform 4, respectively. The PCB board positioning device 5 straightens the PCB board and presses it into the PCB board detection platform 3, so that the PCB board detection platform 3 can detect the operation of the PCB board. The pump body detection device 6 detects the operation of the pump body on the pump body detection platform 4. The PCB board positioning device 5 rotates to pop the PCB board out of the PCB board detection platform 3. The workpiece clamping device 2 adsorbs the PCB board on the PCB board detection platform 3 and puts it into the pump body on the pump body detection platform 4, so that the pressing device 7 presses the PCB board into the pump body. The workpiece clamping device 2 clamps the pump body with the PCB board on the pump body detection platform 4 and places it on the workpiece conveying device 1, so that the welding device 8 can weld the PCB board and the pump body.

[0043] In this embodiment, since the PCB board needs to be pressed into the PCB board detection platform 3 for detection, the traditional method of directly placing the PCB board into the PCB board detection slot 31 on the PCB board monitoring platform using the suction cup 23 has the following problems: the PCB board cannot make complete contact with the PCB board detection contacts in the PCB board detection slot 31, thus affecting the detection effect; the PCB board cannot fit into the PCB board detection slot 31 and is blocked, thus preventing the PCB board from entering the PCB board detection slot 31 for detection; and the PCB board cannot pop out of the PCB board detection slot 31. However, the PCB board positioning device 5 can solve the above problems well, ensuring the posture of the PCB board pressed into the PCB board detection slot 31 and ensuring that the PCB board makes complete contact with the PCB board detection contacts.

[0044] In this embodiment, the water pump is assembled in an integrated manner through the cooperation of various devices. The PCB board positioning device 5 positions the PCB board, so that the PCB board is pressed into the PCB board detection groove 31 and makes full contact with each PCB board detection contact to improve the detection effect. At the same time, the posture is adjusted during the process of pressing the PCB board into the PCB board detection groove 31 to ensure that the PCB board is pressed down smoothly. After the PCB board is detected, it can be ejected from the PCB board detection groove 31, which facilitates the subsequent assembly and soldering of the PCB board and the pump body.

[0045] In this embodiment, the workpiece conveying device 1 includes: a workpiece conveyor belt and a plurality of carriers 11; each carrier 11 is spaced apart on the workpiece conveyor belt, and each carrier 11 is provided with a PCB board support platform 111 and a pump body support platform 112; the PCB board support platform 111 and the pump body support platform 112 are respectively provided with corresponding placement slots for placing PCB boards and pump bodies respectively.

[0046] In this embodiment, the workpiece conveyor belt serves as a transport mechanism. Each carrier 11 holds a set of PCB boards and pump bodies. Each carrier 11 is also equipped with an identification code. If the PCB board fails the inspection on the PCB board inspection platform 3 or the pump body fails the inspection on the pump body inspection platform 4, the workpiece clamping device 2 will return the PCB board on the PCB board inspection platform 3 and the pump body on the pump body inspection platform 4 to the corresponding PCB board support platform 111 and pump body support platform 112 on the carrier 11. The identification code corresponding to the carrier 11 will be assigned corresponding inspection information. When the carrier 11 moves with the workpiece conveyor belt to the area below the welding device 8, the welding device 8 will not operate on the PCB board and pump body on the carrier 11.

[0047] In this embodiment, the workpiece clamping device 2 includes a four-axis robot 21, a clamping cylinder 22, and a suction cup 23. The four-axis robot 21 is movably disposed above the workpiece conveying device 1, the PCB board inspection platform 3, and the pump body inspection platform 4. The clamping cylinder 22 and the suction cup 23 are located in the movable part of the four-axis robot 21. The four-axis robot 21 drives the clamping cylinder 22 and the suction cup 23 to move so that the clamping cylinder 22 clamps the pump body and the suction cup 23 adsorbs the PCB board.

[0048] In this embodiment, the four-axis robot 21 can drive the clamping cylinder 22 and the suction cup 23 to move freely in space, thereby realizing the functions of clamping the pump body with the clamping cylinder 22 and suction cup 23 adsorbing the PCB board for transfer and placement.

[0049] In this embodiment, the PCB board inspection platform 3 is provided with a PCB board inspection slot 31, and the opening of the PCB board inspection slot 31 is chamfered to guide the PCB board into the PCB board inspection slot 31; PCB board inspection contacts are provided in the PCB board inspection slot 31; the workpiece clamping device 2 places the PCB board into the PCB board inspection slot 31, and the PCB board positioning device 5 straightens the PCB board and presses it into the PCB board inspection slot 31 until the bottom of the PCB board abuts against each of the PCB board inspection contacts to detect the operation of the PCB board; the PCB board positioning device 5 rotates to eject the PCB board from the PCB board inspection slot 31.

[0050] In this embodiment, the opening of the PCB board detection slot 31 is chamfered to form a chamfered opening 311, which can initially guide the PCB board into the PCB board detection slot 31. At the same time, the PCB board positioning device 5 accurately positions the PCB board, so that the PCB board moves downward along the PCB board detection slot 31 until the PCB board and the PCB board detection contact are completely released, thereby enabling the detection of the PCB board's operation. Furthermore, under the action of the PCB board positioning device 5, the PCB board pops out of the PCB board detection slot 31, making it convenient for the suction cup 23 to suck the PCB board away from the PCB board detection slot 31.

[0051] In this embodiment, the PCB board positioning device 5 includes an upper PCB board positioning mechanism 51 and a lower PCB board positioning mechanism 52. The upper PCB board positioning mechanism 51 is movably disposed above the PCB board detection platform 3, and the lower PCB board positioning mechanism 52 is movably disposed within the PCB board detection slot 31. When the drilled hole on the PCB board is aligned with the lower PCB board positioning mechanism 52, the workpiece clamping device 2 releases the PCB board, allowing the PCB board to enter the PCB board detection slot 31 under the guidance of the lower PCB board positioning mechanism 52. The upper PCB board positioning mechanism 51 rotates above the lower PCB board positioning mechanism 52 and presses down, that is, the upper PCB board positioning mechanism 51 pushes the PCB board downward, so that the PCB board swings and straightens under the limit of the lower PCB board positioning mechanism 52 until the PCB board is placed horizontally. When the upper PCB board positioning mechanism 51 rotates to push the lower PCB board positioning mechanism 52, the lower PCB board positioning mechanism 52 moves downward under the push of the upper PCB board positioning mechanism 51, that is, the lower PCB board positioning mechanism 52 lifts the PCB board in the PCB board detection slot 31.

[0052] In this embodiment, the upper PCB board positioning mechanism 51 includes: a first cylinder 511, a first rotary motor 512, an upper rotating block 513, an upper movable block 514, and two positioning blocks 515; the movable part of the first cylinder 511 is connected to the first rotary motor 512, and the movable part of the first rotary motor 512 is connected to the upper rotating block 513; the bottom of the upper rotating block 513 is provided with an upper movable groove 5131, and the upper movable block 514 is movably disposed in the upper movable groove 5131 by an upper guide rod 516 and an upper movable spring; corresponding positioning blocks 515 are respectively provided on both sides of the upper movable block 514, and positioning grooves 5151 are provided on the positioning blocks 515; the first rotary motor 512 carries... The movable positioning block 515 rotates so that the positioning groove 5151 is aligned with the upper part of the lower PCB board positioning mechanism 52. The first cylinder 511 drives the upper movable block 514 and the positioning block 515 to press down, so that the upper movable block 514 and the positioning block 515 swing and straighten against the PCB board under the limit of the lower PCB board positioning mechanism 52. An inclined surface is provided in the positioning groove 5151. When the first rotating motor 512 drives the positioning block 515 to rotate, the positioning block 515 pushes against the lower PCB board positioning mechanism 52. That is, the lower PCB board positioning mechanism 52 moves down along the inclined surface in the positioning groove 5151, and the lower PCB board positioning mechanism 52 pushes the PCB board in the PCB board detection groove 31 upward.

[0053] In this embodiment, the first cylinder 511 cooperates with the first rotating motor 512 to enable the upper rotating block 513, the upper movable block 514, and the two positioning blocks 515 to move up and down as well as rotate on the horizontal plane. One end of the upper guide rod 516 is fixed to the upper movable block 514, and the other end of the upper guide rod 516 is movably disposed in the moving groove opened in the upper rotating block 513. At the same time, the upper movable spring is located in the upper movable groove 5131, and the two ends of the upper movable spring are respectively connected to the upper rotating block 513 and the upper movable block 514. The upper movable block 514 and the positioning blocks 515 move downward under the drive of the first cylinder 511. The upper movable block 514 and the positioning blocks 515 push the PCB board downward. By setting the upper movable groove 5131, the upper guide rod 516, and the upper movable spring, a buffering force can be provided. While pushing the PCB board, a buffering force is applied, which can protect the PCB board.

[0054] In this embodiment, the lower PCB board positioning mechanism 52 includes: a sliding block 521, a bullet post 522, and a limiting plate 523; a sliding groove 312 is provided on the inner side wall of the PCB board detection groove 31; the sliding block 521 is movably connected to the movable groove through a T-shaped limiting part, and the sliding block 521 slides along the length direction of the movable groove through a sliding spring 524 provided in the PCB board detection groove 31; the bullet post 522 is movably connected to the top of the sliding block 521 through a lower guide rod 525 and a lower movable spring 526; the limiting plate 523 is located in the PCB board detection groove 31, and an arc-shaped groove 5231 is provided on the limiting plate 523, through which the bullet post 522 passes; when the drilled hole on the PCB board is aligned with the bullet post 522, the first rotating motor 512 drives the positioning block 515 to rotate, so that the lower PCB board positioning mechanism 522 is positioned in the PCB board detection groove 31. Positioning groove 5151 is aligned with bullet post 522. The first cylinder 511 drives the upper movable block 514 and positioning block 515 to press down, so that the upper movable block 514 and positioning block 515 swing and straighten against the PCB board under the limit of bullet post 522. When the first rotating motor 512 drives the positioning block 515 to rotate, the positioning block 515 pushes against bullet post 522. The bullet post 522 squeezes the lower movable spring 526 to slide downward on the lower guide rod 525. The bullet post 522 cooperates with the inclined surface inside the positioning groove 5151 to drive the sliding block 521 to squeeze the sliding spring 524. That is, the sliding block 521 moves along the movable groove and the bullet post 522 moves along the arc groove 5231, so that the arc surface of the bullet post 522 abuts against the PCB board and applies an upward pushing force to lift the PCB board out of the PCB board detection groove 31.

[0055] In this embodiment, the inclined surface opened in the positioning groove 5151 is the positioning inclined surface 5152.

[0056] In this embodiment, when correcting the posture of the PCB board in the PCB board detection slot 31, the bullet post 522 is inserted into the PCB board through a drill hole. The bullet post 522 limits the PCB board, so that the PCB board can only move up and down and swing up and down. Since the upper movable block 514 and the positioning block 515 are set horizontally, the positioning slot 5151 on the positioning block 515 can position the bullet post 522. As a result, the upper movable block 514 and the positioning block 515 press down, and the upper movable block 514 and the positioning block 515 swing and straighten the PCB board under the limitation of the bullet post 522.

[0057] In this embodiment, when the PCB board is lifted from the PCB board detection slot 31, the positioning block 515 rotates under the drive of the first rotating motor 512. The positioning inclined surface 5152 in the positioning slot 5151 cooperates with the arc surface of the bullet column 522, which can push the bullet column 522 down and push the sliding block 521 to move along the movable slot and the bullet column 522 to move along the arc groove 5231. The arc surface of the bullet column 522 contacts the bottom of the PCB board, and the bullet column 522 can resist the PCB board and apply an upward pushing force to lift the PCB board.

[0058] In this embodiment, the pump body testing platform 4 is provided with a pump body testing slot 41; the pump body testing device 6 includes: a pump body moving part 61 and a two-axis manipulator 62; the two-axis manipulator 62 is movably mounted on the pump body moving part 61, and the movable part of the two-axis manipulator 62 is provided with a plurality of pump body testing contacts; the pump body moving part 61 drives the two-axis manipulator 62 to move above the pump body testing slot 41, that is, the two-axis manipulator 62 drives each pump body testing contact to extend into the pump body inside the pump body testing slot 41 to detect the operating status of the pump body.

[0059] In this embodiment, the pump body testing platform 4 carries the pump body through the pump body testing groove 41. At the same time, the two-axis manipulator 62 moves to or away from the pump body testing groove 41 under the action of the pump body moving pair 61. When the two-axis manipulator 62 moves to the top of the pump body testing groove 41, it moves toward the pump body in the pump body testing groove 41 so that each pump body testing contact on the two-axis manipulator 62 extends into the pump body in the pump body testing groove 41 to test the pump body. After the pump body test is completed, the two-axis manipulator 62 moves away from the top of the pump body testing groove 41.
