Description

Technical Field

[0001] This invention relates to the field of chip mounter feeding technology, and more particularly to a circuit board feeding device for a chip mounter. Background Technology

[0002] A pick-and-place machine is a device used to accurately and quickly mount surface mount components (SMD) onto printed circuit boards (PCBs). Existing pick-and-place machines generally use mechanical grippers to place flat mounting components onto a circuit board coated with adhesive, thereby accurately and stably fixing the mounting components onto the circuit board. Before mounting, a flat cleaning mechanism is generally used to clean the adhesive surface of the mounting components.

[0003] Existing surface mount components include flexible components. During the mounting process of flexible components onto the circuit board, it is necessary to ensure that the surface mount components contact the circuit board with the same curvature as the mounting surface of the circuit board. Existing surface mount machines cannot clamp the flexible components into the same curvature as the mounting surface of the circuit board, resulting in impurities such as air bubbles between the two during mounting, which leads to low reliability. Existing surface mount machines cannot clean the surface of the flexible surface mount components before mounting. Summary of the Invention

[0009] Preferably, the upper end of the support body is symmetrically provided with second limiting grooves. A third motor is fixedly connected to each of the two second limiting grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The second motor starts, driving the second threaded rod to rotate. The second threaded rod, in turn, moves the first limiting body to a position close to the mounting element. Then, the third and fourth electric telescopic rods extend. Simultaneously, the sixth motor starts, causing the fourth electric telescopic rod to rotate to an angle perpendicular to the surface of the flexible mounting element. Then, driven by the fourth electric telescopic rod, the open end of the second fixing body moves to a position in contact with the surface of the mounting element. Then, the first air pump starts, causing the air pressure in the cavity of the second fixing body to decrease. This allows for adsorption and clamping at an angle perpendicular to the surface of the flexible mounting element, improving clamping stability while reducing damage to the surface of the mounting element by the second fixing body, thus improving the reliability of the device. When the second limiting body moves to a position close to the second top body, the first electric telescopic rod retracts. At this time, the flexible mounting element falls on the second top body from a very small distance. Then, the first top body at the telescopic end of the first electric telescopic rod moves again to the bottom of the second to last mounting element. This can prevent the mounting element from falling rapidly under the action of gravity during the mounting element loading process, thus preventing damage to the surface of the mounting element. The second air pump starts and can suck air into the fifth slot. Then, the cleaning roll on the side of the fourth fixing body moves with the surface of the mounted component. At the same time, the second air pump can absorb the dust cleaned by the cleaning roll, thereby ensuring that the mounting surface of the mounted component remains clean. Meanwhile, the pressure sensor on the side of the cleaning roll can detect the curvature of the flexible mounting component surface, ensuring that the curvature of the flexible mounting component surface is the same as the curvature of the circuit board mounting surface, thereby avoiding the formation of air bubbles and other issues.

[0016] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Please see Figures 1-9 A circuit board loading device for a chip mounter includes two symmetrically arranged main plates 1, and the upper ends of the two main plates 1 are provided with a clamping and loading mechanism 3 for storing, loading and clamping flexible mounting components.

[0018] In this embodiment, the clamping and feeding mechanism 3 includes two symmetrically arranged connecting plates 31. The lower ends of the two connecting plates 31 are respectively fixedly arranged on the upper surface of the main body plate 1. The upper ends of the two connecting plates 31 are fixedly connected to a support body 32. The upper end of the support body 32 is provided with a receiving groove 36.

[0019] The inner sides of the two connecting plates 31 are symmetrically provided with first limiting grooves 33. The two connecting plates 31 are respectively fixedly connected to the first limiting grooves 33. The drive shaft ends of the two second motors 35 are respectively fixedly connected to the first limiting grooves 33. The sides of the two second threaded rods 317 are provided with first limiting bodies 34, and the sides of the two first limiting bodies 34 are respectively slidably engaged with the first limiting grooves 33.

[0020] The inner sides of the two first limiting bodies 34 are respectively provided with third slots 319. The two first limiting bodies 34 are respectively fixedly connected to the third slots 319. The drive shaft ends of the two fourth motors 318 are respectively fixedly connected to the third electric telescopic rods 320. The telescopic ends of the two third electric telescopic rods 320 are respectively fixedly connected to the first fixing body 321. The sides of the two first fixing bodies 321 are provided with fourth slots 323. The sides of the two first fixing bodies 321 are respectively fixedly connected to the sixth motor. The drive shaft ends of the two sixth motors are fixedly connected to the fourth electric telescopic rods 322 in the fourth slots 323.

[0021] The telescopic ends of the two fourth electric telescopic rods 322 are respectively fixedly connected to fixed shells 324. One end of the two fixed shells 324 is an open structure, and the other end of the two fixed shells 324 is provided with a first through hole 325. The interior of the two fixed shells 324 is respectively fixedly connected to partitions 326. The ends of the two partitions 326 are provided with first air pumps 327. The open ends of the two fixed shells 324 are respectively fixedly connected to second fixing bodies 328. The sides of the two second fixing bodies 328 are respectively provided with cavities 330. The sides of the two second fixing bodies 328 are provided with second through holes 329 communicating with the fixed shells 324.

[0022] The upper end of the support body 32 is symmetrically provided with second limiting grooves 38. The support body 32 is fixedly connected to two second limiting grooves 38 respectively. The drive shaft ends of the two third motors 37 are fixedly connected to first threaded rods 39 in the second limiting grooves 38 respectively. The sides of the two first threaded rods 39 are fitted with second limiting bodies 310. The sides of the two second limiting bodies 310 are slidably fitted with the second limiting grooves 38 respectively. The sides of the two second limiting bodies 310 are respectively provided with first empty grooves 311. The two second limiting bodies 310 are respectively fixedly connected to first electric telescopic rods 312 in the first empty grooves 311 respectively. The telescopic ends of the two first electric telescopic rods 312 are respectively fixedly connected to first top bodies 313. The inner side of the support body 32 is symmetrically provided with several second empty grooves 314. The several second empty grooves 314 are respectively fixedly connected to second electric telescopic rods 315. The telescopic ends of the several second electric telescopic rods 315 are respectively fixedly connected to second top bodies 316.

[0023] Specifically, when the second limiting body 310 moves to a position close to the second top body 316, the first electric telescopic rod 312 retracts. At this time, the flexible mounting element falls above the second top body 316 at a very small distance. Then, the first top body 313 at the telescopic end of the first electric telescopic rod 312 moves again to below the penultimate mounting element. This can prevent the mounting element from falling rapidly under the action of gravity during the mounting element loading process, thus preventing damage to the surface of the mounting element.

[0024] In this embodiment, the side of the support 32 is provided with a cleaning mechanism 4 for cleaning the flexible mounting elements.

[0025] The cleaning mechanism 4 includes a third fixing body 41 fixedly disposed on the side of the support body 32. The side of the third fixing body 41 is provided with a guide groove 43. A fifth motor 42 is fixedly connected to the side of the third fixing body 41. A third threaded rod 47 is fixedly connected to the drive shaft end of the fifth motor 42 in the guide groove 43. A guide block 49 is provided on the side of the third threaded rod 47. The side of the guide block 49 is slidably engaged with the guide groove 43.

[0026] A seventh electric telescopic rod 48 is fixedly connected to the side of the guide block 49. A fifth electric telescopic rod 44 is fixedly connected to the telescopic end of the seventh electric telescopic rod 48. A sixth electric telescopic rod 45 is fixedly connected to the telescopic end of the fifth electric telescopic rod 44. A connecting rod 46 is fixedly connected to the telescopic end of the sixth electric telescopic rod 45. A fourth fixing body 410 is fixedly connected to the upper end of the connecting rod 46. A fifth slot 412 is opened at the upper end of the fourth fixing body 410. A second air pump 413 is provided at the lower end of the fourth fixing body 410. A cleaning roll 411 is rotatably connected to the side of the fourth fixing body 410. Several pressure sensors are fixedly connected to the side of the cleaning roll 411.

[0027] Specifically, the fourth fixing body 410 moves along the surface of the mounting element under the drive of the fifth electric telescopic rod 44 and the sixth electric telescopic rod 45. During the movement, the second air pump 413 is started and can suck air into the fifth empty slot 412. Then, the cleaning roll 411 on the side of the fourth fixing body 410 moves with the surface of the mounting element, and at the same time, the second air pump 413 can absorb the dust cleaned by the cleaning roll 411.

[0028] In this embodiment, the sides of the two main body plates 1 are provided with a transmission mechanism 2 for transporting the circuit board, and the lower ends of the two main body plates 1 are symmetrically connected with support columns 11, and the lower ends of several support columns 11 are respectively fixedly connected with support plates 12.

[0029] The transmission mechanism 2 includes two first fixed rods 24 rotatably disposed on the inner side of the main body plate 1. The sides of the two first fixed rods 24 are fixedly connected to transmission rollers 23. The sides of the two transmission rollers 23 are closely attached to a conveyor belt 22. The side of the main body plate 1 is fixedly connected to a first motor 21. The transmission shaft end of the first motor 21 is fixedly connected to the first fixed rods 24.

[0030] Specifically, the first motor 21 drives the first fixed rod 24 to rotate, and the first fixed rod 24 in turn drives the transmission roller 23 to rotate, thereby driving the conveyor belt 22 to move. After that, the circuit board is coated with glue and placed on the surface of the conveyor belt 22 in a fixed position.

[0031] In use, the main board 1 is placed on a horizontal surface and then limited by the support plate 12. The first motor 21 is started, which drives the first fixed rod 24 to rotate. The first fixed rod 24, in turn, drives the transmission roller 23 to rotate, thereby moving the conveyor belt 22. After applying adhesive to the circuit board, it is placed on the surface of the conveyor belt 22 in a fixed position. The flexible mounting component is placed in the support body 32. When loading is required, the third motor 37 is started, which drives the first threaded rod 39 to rotate. The first threaded rod 39, in turn, drives the second limiting body 310 to move below the second to last mounting component. Then, several second electric telescopic rods 315 retract, driving the second top body 316 away from below the mounting component. At the same time, the second motor 35 is started, driving the first... The second threaded rod 317 rotates, and in conjunction with it, moves the first limiting body 34 to a position close to the mounting element. Then, the third electric telescopic rod 320 and the fourth electric telescopic rod 322 extend. At the same time, the sixth motor starts, causing the fourth electric telescopic rod 322 to rotate to an angle perpendicular to the surface of the flexible mounting element. Then, driven by the fourth electric telescopic rod 322, the open end of the second fixing body 328 moves to a position in contact with the surface of the mounting element. Then, the first air pump 327 starts, and the first air pump 327 reduces the air pressure in the cavity 330 of the second fixing body 328, thereby adsorbing and clamping at an angle perpendicular to the surface of the flexible mounting element. This improves clamping stability while reducing damage to the surface of the mounting element by the second fixing body 328, thus improving the reliability of the device.

[0032] After the second fixing body 328 clamps and limits the bottom mounting element by the clamping and feeding mechanism 3, the third motor 37 drives the second limiting body 310 to move downward. When the second limiting body 310 moves to a position close to the second top body 316, the first electric telescopic rod 312 retracts. At this time, the flexible mounting element falls on the second top body 316 with a very small distance. Then, the first top body 313 at the telescopic end of the first electric telescopic rod 312 moves again to the bottom of the second to last mounting element. This can prevent the mounting element from falling quickly under the action of gravity during the mounting element feeding process and prevent damage to the surface of the mounting element.

[0033] After the two second fixing bodies 328 clamp and limit the surface of the mounting component, the fourth fixing body 410 moves along the surface of the mounting component under the drive of the fifth electric telescopic rod 44 and the sixth electric telescopic rod 45. During the movement, the second air pump 413 is started, which can suck air into the fifth empty slot 412. Then, the cleaning roll 411 on the side of the fourth fixing body 410 moves with the surface of the mounting component. At the same time, the second air pump 413 can absorb the dust cleaned by the cleaning roll 411, thereby ensuring that the mounting surface of the mounting component remains clean. Meanwhile, the pressure sensor on the side of the cleaning roll 411 can detect the curvature of the flexible mounting component surface, ensuring that the curvature of the flexible mounting component surface is the same as the curvature of the circuit board mounting surface, thereby avoiding the formation of air bubbles and other issues.

[0034] The foregoing has shown and described 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.
