Description

Technical Field

[0001] The utility model relates to the technical field of sucker mechanisms, in particular to a telescopic sucker mechanism. Background Technique

[0002] A PCB automatic loading and unloading machine is a device that places a PCB board from a carrier onto a PCB production line or receives it from the PCB production line onto the carrier. Taking the board loading machine as an example, the PCB automatic loading machine transports the board on the carrier to the conveyor line through a fixture. The production line requires that when the PCB board is placed on the carrier, it should be stable and fast, and phenomena such as PCB board banding and sucking two boards should not occur.

[0003] The sucker mechanism of the existing automatic loading machine realizes board sucking by means of a vacuum generator and a suction nozzle, and realizes board separation through a separate vibrating sucker and a blowing device. Since there are large differences in the structures of PCB boards in different processes, the adhesion of some piles of boards placed on the carrier is relatively high. Separating the boards through a separate vibrating sucker and a blowing device will cause two boards not to be separated, resulting in the next board being lifted during transportation, and the scrapping of the boards and the normal use of the equipment; or sucking two boards onto the conveyor line, affecting the normal use of the equipment. For this reason, a telescopic sucker mechanism is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a telescopic sucker mechanism to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A telescopic sucker mechanism, including two support frames, a plurality of mounting plates are fixed on one side of the support frame, a cylinder is installed on one side of the mounting plate, and a sucker is installed at the push rod end of the cylinder;

[0006] A slide rail is fixed at the middle of the top of one of the support frames, a limit frame is fixed at the top of the other support frame, a connecting frame is slidably connected inside the track groove of the slide rail, and a bolt is threadedly connected to one side of the slide rail;

[0007] A disassembly component is arranged on one side of the connecting frame;

[0008] The disassembly component includes a fixed frame, and sliding grooves are opened on the inner sides of the fixed frame and one of the support frames.

[0009] Preferably, one end of the bolt abuts against one side of the connecting frame, and the bottom of the connecting frame is located on one side of the top of the limit frame.

[0010] Preferably, a sliding plate is slidably connected inside the sliding groove, and a pulling block is fixed at one end of the sliding plate.

[0011] Preferably, a spring is connected between one side of the above-mentioned sliding plate and the inner side of the sliding groove, and a locking rod is fixed on one side of the sliding plate.

[0012] Preferably, a limiting rod is fixed on one side of the bottom of the above-mentioned connecting frame, and a limiting groove for inserting the limiting rod is formed on one side of the connecting frame and the limiting frame.

[0013] Preferably, a locking groove is formed on one side of the above-mentioned limiting rod, the outer side of the locking rod is inserted into the inner side of the locking groove, and one side of the fixing frame is fixed to one side of the support frame.

[0014] Preferably, when the outer side of the locking rod leaves the inner side of the locking groove, the connecting frame is in a removed state, and when the outer side of the locking rod is inserted into the inner side of the locking groove, the connecting frame is in a fixed state.

[0015] Compared with the prior art, the present utility model adopts the above technical solutions and has the following technical effects:

[0016] First, by controlling the movement of the push rod end of the cylinder, it is ensured that the suction cup can accurately contact the PCB board and generate sufficient negative pressure to stably suck the PCB board. The extension and retraction operations of the push rod end of the cylinder cause the PCB board to vibrate at the bottom of the suction cup, effectively promoting the separation between the stacked PCB boards, avoiding phenomena such as tape carrying and sucking two pieces, and ensuring that only one board is stably ejected each time.

[0017] Second, by simply pulling the pull block and lifting the connecting frame upward, the mechanism can be easily disassembled into three parts, greatly simplifying the disassembly and assembly processes, enabling the operator to quickly and conveniently perform maintenance work or replace components. After the mechanism is disassembled into three parts, the volume and weight of each part are relatively small, so the storage space can be utilized more efficiently. The convenient disassembly process makes the components inside the mechanism easier to access and inspect. During maintenance, the problem components can be located more quickly and replaced or repaired, thus improving the maintainability convenience of the mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment

[0028] Please refer to Figures 1-5, the present utility model provides a technical solution: a telescopic suction cup mechanism, including two support frames 1. A blower is arranged on one side of the support frame 1. A plurality of mounting plates 9 are fixed on one side of the support frame 1. A cylinder 3 is installed on one side of the mounting plate 9. A suction cup 4 is installed at the push rod end of the cylinder 3. The air inlet end and the air outlet end of the suction cup 4 are connected to a vacuum generator through an air pipe. The suction cup 4 is connected to a solenoid valve. The support frame 1 and the connecting frame 2 move downward, so that a plurality of suction cups 4 are located on the top of the PCB board. At this time, the solenoid valve controls the push rod end of the cylinder 3 to move downward, so that the cylinder 3 pushes the bottom of the suction cup 4 to contact the top of the PCB board. The extension and retraction operations of the push rod end of the cylinder 3 cause the PCB board to vibrate at the bottom of the suction cup 4, effectively promoting the separation between the stacked PCB boards, avoiding phenomena such as tape carrying and sucking two pieces, and ensuring that only one board is stably ejected each time;

[0029] In the middle of the top of one of the support frames 1, a slide rail 5 is fixed. On the top of the other support frame 1, a limit frame 7 is fixed. The connecting frame 2 is slidably connected to the inner side of the track groove of the slide rail 5. One side of the slide rail 5 is threadedly connected with a bolt 6. One end of the bolt 6 abuts against one side of the connecting frame 2. The bottom of the connecting frame 2 is located on one side of the top of the limit frame 7. Loosen the bolt 6, so that the connecting frame 2 slides inside the slide rail 5. When one of the support frames 1 moves to the required position, tighten the bolt 6, so that one end of the bolt 6 abuts against one side of the connecting frame 2. According to this method, the width of the two support frames 1 can be adjusted;

[0030] A disassembly component 8 is arranged on one side of the connecting frame 2. In order to facilitate the disassembly of the mechanism, the disassembly component 8 is provided. The disassembly component 8 includes a fixed frame 81. Slide grooves 82 are opened on the inner sides of the fixed frame 81 and one of the support frames 1. A slide plate 84 is slidably connected to the inner side of the slide groove 82. One end of the slide plate 84 is fixed with a pull block 83. Pull the pull block 83 to one side. The pull block 83 drives the slide plate 84 to slide inside the slide groove 82. At the same time, the slide plate 84 compresses the spring 87. Subsequently, the slide plate 84 drives the lock rod 89 to leave the inside of the lock groove 88. A spring 87 is connected between one side of the slide plate 84 and the inner side of the slide groove 82. A lock rod 89 is fixed on one side of the slide plate 84. A limit rod 86 is fixed on one side of the bottom of the connecting frame 2. Limit grooves 85 for inserting the limit rod 86 are opened on one side of the connecting frame 2 and the limit frame 7. A lock groove 88 is opened on one side of the limit rod 86. The outer side of the lock rod 89 is inserted into the inside of the lock groove 88. One side of the fixed frame 81 is fixed to one side of the support frame 1. Pull the connecting frame 2 upward, so that the limit rod 86 at the bottom of the connecting frame 2 leaves the inside of the limit groove 85. At this time, the connection between the connecting frame 2 and the other support frame 1 can be separated. After disassembling the mechanism, the mechanism can be easily disassembled into three parts, reducing the storage space of the mechanism during storage.

[0031] When the outer side of the lock rod 89 leaves the inner side of the lock groove 88, the connecting frame 2 is in the removed state. When the outer side of the lock rod 89 is inserted into the inner side of the lock groove 88, the connecting frame 2 is in the fixed state.

[0032] Working principle: When it is necessary to pick up the PCB board, first move the connecting frame 2 to the top of multiple PCB boards, and then move the support frame 1 and the connecting frame 2 downward so that multiple suction cups 4 are located on the top of the PCB board. At this time, the solenoid valve controls the push rod end of the cylinder 3 to move downward, so that the cylinder 3 pushes the bottom of the suction cup 4 to contact the top of the PCB board. At this time, a negative pressure is generated inside the vacuum generator, so that the suction cup 4 sucks up the PCB board. Then the solenoid valve controls the push rod end of the cylinder 3 to extend and retract, so that the PCB board adsorbed at the bottom of the suction cup 4 shakes, separating the PCB board surface. After the PCB board is separated, it is placed on the conveyor line. This suction cup 4 mechanism has a compact structure, simple adjustment, a large separation area, avoiding phenomena such as taking the board with another one attached or sucking two pieces, and realizing a stable output of one board at a time.

[0033] When it is necessary to adjust the width of the two support frames 1, only need to loosen the bolt 6 so that the connecting frame 2 slides inside the slide rail 5. When one of the support frames 1 moves to the required position, tighten the bolt 6 so that one end of the bolt 6 abuts against one side of the connecting frame 2. In this way, the width of the two support frames 1 can be adjusted.

[0034] When it is necessary to disassemble this mechanism, only need to loosen the bolt 6 so that one side of the bottom of one of the support frames 1 and the connecting frame 2 is separated first, and then pull the pull block 83 to one side. The pull block 83 drives the slide plate 84 to slide inside the chute 82. At the same time, the slide plate 84 compresses the spring 87. Subsequently, the slide plate 84 drives the lock rod 89 to leave the inner side of the lock groove 88. Finally, pull the connecting frame 2 upward so that the limit rod 86 at the bottom of the connecting frame 2 leaves the inner side of the limit groove 85. At this time, the connection between the connecting frame 2 and the other support frame 1 can be separated. After disassembling this mechanism, this mechanism can be conveniently disassembled into three parts, reducing the storage space of this mechanism during storage.

[0035] In summary, by controlling the movement of the push rod end of the cylinder 3, it is ensured that the suction cup 4 can accurately contact the PCB board and generate sufficient negative pressure to stably suck the PCB board. The extension and retraction operations of the push rod end of the cylinder 3 cause the PCB board to shake at the bottom of the suction cup 4, effectively promoting the separation between the stacked PCB boards, avoiding phenomena such as taking the board with another one attached or sucking two pieces, and ensuring that only one board is stably output each time.

[0036] By simply pulling the pull block 83 and lifting the connecting frame 2 upward, the mechanism can be easily disassembled into three parts, greatly simplifying the disassembly and assembly process, enabling the operator to quickly and conveniently perform maintenance work or replace components. After the mechanism is disassembled into three parts, the volume and weight of each part are relatively small, so the storage space can be utilized more efficiently. The convenient disassembly process makes each component inside the mechanism easier to access and inspect. During maintenance, the problem components can be located and replaced or repaired more quickly, thus improving the maintainability convenience of the mechanism.
