Description

Technical Field

[0001] The utility model relates to the technical field of PCB processing, in particular to a sucker device for an automatic board collecting machine which can prevent boards from falling off. Background Art

[0002] PCB boards consist of a non-conductive substrate and a conductive layer covering its surface. The conductive layer is usually made of copper foil, and the circuit pattern is formed by chemical etching or mechanical processing. When processing PCB boards, robotic arms and board collectors are usually used to transport the PCB boards.

[0003] The existing board collecting machine usually collects boards by pneumatic suction nozzles and suction cups. Since some special PCB boards have many large holes among different types of PCB boards, the pneumatic suction nozzles and suction cups can easily cause the PCB boards to be loose during the suction process. As a result, boards may fall off or fail to be sucked up and automatically collected during the subsequent transportation process. Board falling can cause the equipment to stop and jam the board, and the copper surface can be scratched. When the board cannot be sucked up and automatically collected, it needs to be manually collected. Therefore, this design method can easily cause the board collecting machine to malfunction and cause PCB board quality problems. In view of the shortcomings of the existing technology, the utility model provides an automatic board collecting machine suction cup device that prevents boards from falling off to solve the above problems.

Through the design of the locking component, the disassembly and assembly between the clamping seat and the push table is convenient and quick, so that the clamping seat can be easily replaced according to the model of the PCB board, ensuring the stability of the secondary clamping of PCB boards of different thicknesses.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a suction cup device for an automatic plate collecting machine to prevent plate from falling, comprising a suction cup bracket fixedly connected to a robotic arm, the suction cup bracket being provided with multiple groups of pneumatic suction cup bodies, and the robotic arm being equipped with a secondary clamping mechanism;

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the present application solves the problem that the existing board collecting machine usually collects boards by using a pneumatic suction nozzle and a suction cup, by providing a suction cup device for an automatic board collecting machine that prevents boards from falling off. Since some special PCB boards among different types of PCB boards have many large holes, the pneumatic suction nozzle and the suction cup can easily cause the PCB boards to be loose during the suction process, resulting in the problem of boards falling off or being unable to be sucked up automatically during the subsequent transportation process.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The utility model discloses a sucker device for an automatic plate collecting machine to prevent the plate from falling off. Figure 1-4 As shown, it includes a suction cup bracket 2 fixedly connected to a robot arm 1, a plurality of pneumatic suction cup bodies 201 are provided on the suction cup bracket 2, and a secondary clamping mechanism 3 is mounted on the robot arm 1;

[0025] The secondary clamping mechanism 3 includes a support frame 301 fixedly connected to the suction cup bracket 2 and a cylinder body 302 fixedly connected to the support frame 301;

[0026] The output end of the cylinder body 302 is fixedly connected to the pushing platform 303, and the clamping seat 304 is movably connected to the pushing platform 303. The pushing platform 303 is fixedly connected to the lateral support rod 3031, and the lateral support rod 3031 is slidably connected to the support frame 301. The support frame 301 is provided with a through groove corresponding to the lateral support rod 3031. Through the design of the lateral support rod 3031, the device makes it possible for the pushing platform 303 and the clamping seat 304 to move when the cylinder body 302 drives the pushing platform 303 and the clamping seat 304 to move, thereby providing lateral support for the pushing platform 303 and the clamping seat 304, ensuring that the pushing platform 303 and the clamping seat 304 are subjected to stable force, thereby achieving a good secondary clamping effect of the PCB board.

[0027] The device is designed with a secondary clamping mechanism 3, so that when the robot arm 1 drives the suction cup bracket 2 and the multiple sets of pneumatic suction cup bodies 201 to move and lift the PCB board for transportation, the PCB board can be clamped for the second time, thereby ensuring good stability and safety during the transportation of the PCB board.

[0028] In the secondary clamping mechanism 3 , the cylinder body 302 drives the push platform 303 to move, and the push platform 303 drives the clamping seat 304 to move, so that the two groups of clamping seats 304 clamp both sides of the PCB board.

[0029] A locking assembly 305 is provided between the clamping seat 304 and the pushing platform 303. The locking assembly 305 includes a clamping block 3052 fixedly connected to the clamping seat 304 and a mounting seat 3051 fixedly connected to the pushing platform 303. The clamping block 3052 is movably clamped in the mounting seat 3051. A sleeve 3053 is fixedly connected to the side of the mounting seat 3051. A locking rod 3054 is movably inserted into the interior of the sleeve 3053. A locking hole 30521 is provided on the clamping block 3052. The locking rod 3054 is movably inserted into the locking hole 30521. A slider 3055 is fixedly connected to the locking rod 3054. The slider 3055 is slidably connected to the interior of the sleeve 3053. A spring 3056 is fixedly connected between the slider 3055 and the sleeve 3053.

[0030] The suction cup device of the automatic board collecting machine for preventing the board from falling off is designed with a locking component 305, which makes the disassembly and assembly between the clamping seat 304 and the push platform 303 convenient and quick. Therefore, the clamping seat 304 is easy to replace according to the model of the PCB board, ensuring the stability of the secondary clamping of PCB boards of different thicknesses.

[0031] When installing the clamping seat 304, first pull the locking rod 3054 so that the locking rod 3054 drives the slider 3055 to move and squeeze the spring 3056. At this time, align the blocking block 3052 with the internal clamping of the mounting seat 3051. After it is fully clamped, release the locking rod 3054 to reset the spring 3056 and push the slider 3055 to move. The slider 3055 drives the locking rod 3054 to move. When the locking rod 3054 is inserted into the lock hole 30521, the position of the blocking block 3052 and the clamping seat 304 is locked, thereby realizing the installation of the clamping seat 304. When the clamping seat 304 needs to be disassembled and replaced, the disassembly process is the opposite of the above installation process. The operation is simple and convenient, saving time and effort.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
