DETAILED DESCRIPTION

[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] The utility model provides a grabbing device for a base plate of an exterior wall thermal insulation board, which is suitable for moving the base plate to be composited to a composite work station.

[0033] like Figure 1 , 2 In the embodiments shown in FIGS. 4 and 6 , the frame 103 is used to install various functional components. Specifically, the frame 103 can be welded by profiles such as square tubes, angle steels or bar steels.

[0034] The conveying roller 104 and the positioning mechanism that are transmission-connected to the frame 103 cooperate to deliver the basic board to be moved to the bottom of the grabbing mechanism at a certain angle. Specifically, the positioning mechanism includes a positioning plate 114 arranged at the gap of the conveying roller 104. According to the characteristics of the basic board of the exterior wall insulation board, the two positioning plates 114 are vertically arranged, wherein the positioning plate 114 parallel to the conveying roller 104 is used to block the moving basic board, and a push plate 116 is provided at the end of the telescopic rod of the second push rod 118. When the basic board is blocked, the telescopic rod of the second push rod 118 extends out, and under the action of the second push rod 118, the side of the basic board is aligned with the other positioning plate 114, thereby achieving the positioning effect.

[0035] The grabbing mechanism is used to grab the base plate and move the base plate to the next station. Specifically, the grabbing mechanism includes a support 102, which is slidably connected to the frame 103 via a slideway 120, and the first driving motor is used to drive the support 102 to slide at the frame 103. Hanging plates 108 are provided at the support 102 and the mounting plate 109, and the mounting plate 109 is slidably connected to the support 102 through each hanging plate 108. In order to ensure that the mounting plate 109 has only one degree of freedom in a moving direction relative to the support 102 and reduce the resistance of the mounting plate 109 when moving up and down, the hanging plates 108 at the mounting plate 109 and the hanging plates 108 at the support 102 are slidably connected via a linear shaft 106 and a first linear bearing 107. The first push rod 101 provided at the support 102 is used to drive the mounting plate 109 to move up and down. Each suction cup 105 provided at the mounting plate 109 is used to generate negative pressure so as to grab the base sheet at the conveying roller 104. Specifically, each suction cup 105 is connected to the mounting plate 109 via a support rod 112, and each support rod 112 is provided with a through hole that interpenetrates with the suction cup 105. In an optional form of air path, the through holes on the upper part of each support rod 112 converge to an exhaust port through an air guide pipe, and a solenoid valve is provided at the exhaust port, and the solenoid valve is used to regulate the air pressure difference between the enclosed space formed by each suction cup 105 and the base sheet and the outside world. When in use, when the first push rod 101 descends to the maximum height, the solenoid valve keeps the exhaust port open all the time, and when each suction cup 105 is in contact with the base sheet and compressed, the air inside each suction cup 105 is discharged through the exhaust port. When the first push rod 101 executes the retraction instruction, the solenoid valve keeps the exhaust port closed, and the base sheet can be firmly grasped by each suction cup 105 under the action of atmospheric pressure. To ensure the precision of the movement of the first drive motor, the first drive motor may be a servo motor or a stepper motor.

[0036] In order to ensure the rapidity of action execution, the first push rod 101 and the second push rod 118 in this embodiment can both be pneumatic push rods.

[0037] Each of the sensors serves to feed back position information. Specifically, a first sensor 115 is provided at the conveying roller 104. The triggering of the first sensor 115 indicates that the base plate has been positioned at the two positioning plates 114. A second sensor 121 is movably connected at the slide 120 of the frame 103. The second sensor 121 is used to indicate the position of the support 102. The triggering of the second sensor 121 indicates that the gripping mechanism has carried the base plate to the designated position of the next workstation.

[0038] The control unit is provided with a plurality of I / O interfaces, and the first drive motor, each of the sensors, the first push rod 101, the second push rod 118 and the solenoid valve are electrically connected to the corresponding I / O interfaces of the control unit respectively.

[0039] In specific use, when the control unit receives feedback from the first sensor 115, it indicates that the base plate has reached the two positioning plates 114, and at this time the control unit issues an extension command to the second push rod 118. After the extension command of the second push rod 118 is completed, the control unit issues an extension command to the first push rod 101. When the extension command of the first push rod 101 is completed, the control unit issues a closing command to the solenoid valve. When the closing command of the solenoid valve is executed, the control unit issues a retraction command to the first push rod 101. When the retraction command of the first push rod 101 is executed, the control unit issues an execution command to the first drive motor, so that the gripping mechanism moves to the next station. When the second sensor 121 is triggered, it indicates that the base plate has reached the specified position. The control unit issues an extension action to the first push rod 101. When the extension action of the first push rod 101 is completed, the control unit issues an opening command to the solenoid valve. When the opening command of the solenoid valve is completed, the control unit issues a retraction command to the first push rod 101. When the retraction instruction of the first push rod 101 is completed, the control unit sends an execution instruction to the first drive motor, so that the grabbing mechanism returns to the initial position.

[0040] It is understandable that the functions of the control unit are realized by the control unit hardware itself and the program installed in the control unit. It should be noted that the program is written based on the working principle of the grabbing device for the base plate of the external wall insulation board. Among them, when writing the program, the specific assembly language, called functions, and data debugging methods are all used as prior art, and the program installed in the control unit of this application is not protected by this solution.

[0041] The chip of the control unit may be a single-chip microcomputer or a PLC programmable controller.

[0042] Embodiment 2:

[0043] On the basis of Example 1, when the base plate is heavier, in order to prevent the base plate from falling off when grabbing the base plate due to insufficient pressure difference between each suction cup 105 and the outside world, a negative pressure device is externally connected to the exhaust port. The solenoid valve can be in the form of a three-way valve. The pressure difference can be ensured by the negative pressure device, thereby improving the firmness of each suction cup 105 in sucking the base plate.

[0044] In this embodiment, a pressure regulating valve 113 is provided at each suction cup 105 , and the pressure regulating valve 113 can prevent the base plate from being damaged when the pressure difference generated by the negative pressure device is too large.

[0045] Embodiment 3:

[0046] On the basis of Example 1 or 2, Figure 2 , 3 In the embodiment shown, in order to prevent the grabbing mechanism or the base plate from being damaged due to excessive travel of the first push rod 101 during the process of grabbing the base plate or releasing the base plate at the next station, an optional form of connection between the suction cup 105 and the mounting plate 109 is provided in this embodiment.

[0047] Specifically, each support rod 112 is slidably connected to the mounting plate 109, and the upper part of each support rod 112 is threadedly connected to the limit block 110. A first spring 111 is sleeved at each support rod 112. When the suction cup 105, the support rod 112 and the mounting plate 109 are assembled, the two ends of the first spring 111 are respectively in conflict with the mounting plate 109 and the suction cup 105.

[0048] In this embodiment, in order to reduce the friction between the support rods 112 and the mounting plate 109 , a second linear bearing is disposed between each support rod 112 and the mounting plate 109 .

[0049] like Figure 5 In the illustrated embodiment, another optional form is provided to prevent the gripping mechanism or the base sheet from being damaged due to excessive stroke of the first push rod 101 when the gripping mechanism is gripping the base sheet or releasing the base sheet at the next station.

[0050] Specifically, a second spring 119 is provided at the end of the telescopic rod of the first push rod 101 , and the other end of the second spring 119 is connected to the hanging plate 108 at the mounting plate 109 .

[0051] Embodiment 4:

[0052] On the basis of any one of embodiments 1-3, Figure 4In the illustrated embodiment, in order to prevent the second push rod 118 from damaging the base plate due to the thrust of the second push rod 118 when pushing the base plate, a third spring 117 is provided at the telescopic rod of the second push rod 118. The elastic force of the third spring 117 can not only ensure the effective combination of the base plate and the positioning plate 114, but also prevent the base plate from being damaged due to excessive thrust of the second push rod 118.

[0053] The embodiments described above are only preferred specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present utility model according to the technical solution and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
