Description

Technical Field

[0001] This utility model belongs to the field of suction cup technology, and specifically relates to a suction cup device for PCB forming equipment. Background Technology

[0002] When processing PCBs, PCB forming equipment needs to use a suction cup device to pick up and move the PCBs.

[0003] Currently, traditional suction cup devices still have certain problems in use. For example, traditional suction cup devices cannot clean the PCB board in advance before picking it up. During the PCB board processing, dust can easily fall on the PCB board surface. This dust will damage the seal between the suction cup and the PCB board surface, allowing air to enter, resulting in a decrease in suction power. It will also change the adsorption surface characteristics, making the surface no longer smooth and flat, resulting in a weaker suction power. In addition, dust can also enter the air holes of the suction cup, causing blockage of the air holes. Utility Model Content

[0004] The purpose of this utility model is to provide a suction cup device for PCB forming equipment, which has the advantages of blowing and adjusting the blowing range of the PCB board.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a suction cup device for PCB forming equipment, comprising a base, an air chamber connected to the top of the base, a groove formed at the bottom of the base, a blowing chamber inside the groove, and rotating sleeves rotatably connected to the base at both ends of the blowing chamber. A sleeve is fixedly connected to the top of the air chamber, a shaft is rotatably connected inside the air chamber, a first fan blade fixedly sleeved to the shaft is provided inside the air chamber, one end of the shaft extends into the sleeve and is fixedly sleeved to a second fan blade, the blade surfaces of the first and second fan blades are arranged in opposite directions, an air pipe is connected to the surface of the sleeve, a connecting rod is rotatably connected to the surface of the sleeve, a transmission mechanism is provided inside the sleeve, a turntable fixedly sleeved to the connecting rod is provided on the surface of the sleeve, a sliding column is fixedly connected to the surface of the turntable, and a sliding frame fixedly connected to the rotating sleeve is slidably connected to the surface of the sliding column.

[0006] The present invention is further configured such that the transmission mechanism includes a first bevel gear, the first bevel gear is fixedly sleeved on the surface of the shaft, and a second bevel gear is meshed on the surface of the first bevel gear and fixedly sleeved on the connecting rod.

[0007] The above technical solution is adopted: when the shaft rotates, it can drive the first bevel gear to rotate, and the rotation of the first bevel gear can drive the second bevel gear to rotate, thereby driving the connecting rod to rotate.

[0008] The present invention is further configured such that one end of the air passage tube extends into the interior of the blowing chamber through a rotating sleeve.

[0009] Using the above technical solution: when the second fan blade inside the sleeve rotates, it can draw in external air into the sleeve and deliver it to the blowing chamber through the air pipe.

[0010] The present invention is further configured such that a limiting block is fixedly connected inside the sleeve, and the limiting block is rotatably connected to the connecting rod.

[0011] The above technical solution involves limiting the rotation of the connecting rod.

[0012] The present invention is further configured such that a suction cup body is assembled at the bottom of the base, and the suction cup body is connected to the inner cavity of the base through a pipe.

[0013] Using the above technical solution, the PCB board can be extracted.

[0014] The present invention is further configured such that a mounting base is fixedly sleeved on the surface of the air cavity.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model has a first fan blade installed inside the air chamber. When the external vacuum equipment is started, the airflow enters the external vacuum equipment through the air chamber. The airflow can drive the first fan blade to rotate. Under the action of the shaft, it drives the second fan blade to rotate, drawing external air into the sleeve and delivering it to the blowing chamber through the air pipe. When the external travel device moves the suction cup device to the top of the PCB board, the gas blown out of the blowing chamber can clean the PCB board in advance to prevent dust on the surface of the PCB board from affecting the suction of the suction cup device.

[0020] 2. Through the design of the connecting rod, the transmission mechanism can drive the turntable on the connecting rod to rotate. Under the action of the sliding column, the sliding frame can be driven to swing back and forth around the rotating sleeve, thereby driving the blowing chamber to swing back and forth, adjusting the blowing range and increasing the cleaning area.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A suction cup device for PCB forming equipment includes a base 1, an air chamber 2 connected to the top of the base 1, and an external air pipe mounting head 19 connected to the surface of the air chamber 2. The external air pipe mounting head 19 facilitates connection of the suction cup device to an external vacuum device. A suction cup body 17 is mounted on the bottom of the base 1, and the suction cup body 17 is connected to the inner cavity of the base 1 via a pipe. The suction cup body 17 can pick up PCB boards. A groove 3 is formed at the bottom of the base 1, and a blowing chamber 4 is provided inside the groove 3. Both ends of the blowing chamber 4 are connected to rotating sleeves 5 that are rotatably connected to the base 1. A sleeve 6 is fixedly connected to the top of the air chamber 2, and a shaft 7 is rotatably connected inside the air chamber 2. The internal structure is equipped with a first fan blade 8 that is fixedly sleeved with the shaft 7. One end of the shaft 7 passes through the interior of the sleeve 6 and is fixedly sleeved with a second fan blade 9. The blade surfaces of the first fan blade 8 and the second fan blade 9 are arranged in opposite directions. The surface of the sleeve 6 is connected to an air passage pipe 10. One end of the air passage pipe 10 passes through the rotating sleeve 5 and enters the interior of the blowing chamber 4. When the second fan blade 9 inside the sleeve 6 rotates, it can draw in external air into the interior of the sleeve 6 and deliver it to the interior of the blowing chamber 4 through the air passage pipe 10. The surface of the air chamber 2 is fixedly sleeved with a mounting base 18. By setting the mounting base 18, it is convenient for the suction cup device to be installed on an external travel device.

[0032] Brief description of usage: Connect the external air pipe mounting head 19 to the air pipe of the external vacuum equipment. When the external vacuum equipment is started, air enters the cavity of the base 1 through the suction cup body 17, and then enters the air chamber 2. The airflow drives the first fan blade 8 to rotate, and under the action of the shaft 7, it drives the second fan blade 9 to rotate. Since the blades of the first fan blade 8 and the second fan blade 9 are set to opposite directions, the second fan blade 9 starts to draw external air into the sleeve 6 and delivers it to the blowing chamber 4 through the air pipe 10. When the external travel device moves the suction cup device to the top of the PCB board, it blows the PCB board in advance. When the suction cup body 17 contacts the PCB board, the airflow stops, the first fan blade 8 stops rotating, and then the second fan blade 9 stops rotating, so that the blowing chamber 4 stops blowing air.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7A suction cup device for PCB forming equipment includes a base 1, an air chamber 2 connected to the top of the base 1, a groove 3 formed at the bottom of the base 1, a blowing chamber 4 inside the groove 3, and rotating sleeves 5 rotatably connected to the base 1 at both ends of the blowing chamber 4. A sleeve 6 is fixedly connected to the top of the air chamber 2, a shaft 7 is rotatably connected inside the air chamber 2, a first blade 8 fixedly sleeved to the shaft 7 is arranged inside the air chamber 2, one end of the shaft 7 passes through the inside of the sleeve 6 and is fixedly sleeved with a second blade 9, the blade surfaces of the first blade 8 and the second blade 9 are arranged in opposite directions, an air pipe 10 is connected to the surface of the sleeve 6, a connecting rod 11 is rotatably connected to the surface of the sleeve 6, and a limiting block 16 is fixedly connected inside the sleeve 6, the limiting block 16 is rotatably connected to the connecting rod 11, and by setting the limiting block 16, the connecting rod 11 is rotatably connected to the air pipe 10. The connecting rod 11 is rotated and limited. The sleeve 6 is equipped with a transmission mechanism 12. The transmission mechanism 12 includes a first bevel gear 121, which is fixedly sleeved on the surface of the shaft 7. The surface of the first bevel gear 121 meshes with a second bevel gear 122, which is fixedly sleeved on the connecting rod 11. By setting the first bevel gear 121 and the second bevel gear 122, when the shaft 7 rotates, it can drive the first bevel gear 121 to rotate. The rotation of the first bevel gear 121 can drive the second bevel gear 122 to rotate, thereby driving the connecting rod 11 to rotate. The surface of the sleeve 6 is equipped with a turntable 13, which is fixedly sleeved on the connecting rod 11. The surface of the turntable 13 is fixedly connected with a sliding column 14. The surface of the sliding column 14 is slidably connected with a sliding frame 15, which is fixedly connected to the rotating sleeve 5.

[0035] Brief description of the usage process: When the shaft 7 drives the first bevel gear 121 to rotate, the first bevel gear 121 drives the second bevel gear 122 to rotate, thereby driving the connecting rod 11 to rotate, which in turn drives the sliding column 14 on the turntable 13 to rotate around the turntable 13 as the axis. With the use of the sliding frame 15, the sliding frame 15 can be driven to swing back and forth around the rotating sleeve 5 as the center, causing the rotating sleeve 5 to swing back and forth, thereby driving the blowing chamber 4 to swing back and forth, so as to adjust the blowing range.
