[0035] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] This utility model discloses an IC feeder and an IC plug-in machine.

[0039] As Figures 1 to 6 shown, the IC feeder includes an IC loading mechanism, an IC ejecting mechanism, and an IC tube loading mechanism disposed between the IC loading mechanism and the IC ejecting structure.

[0040] The IC loading mechanism includes an IC guiding groove 10 and a linear vibrator 20 mounted on the IC guiding groove 10. The IC guiding groove 10 is used to guide the IC, and the linear vibrator 20 is used to drive the IC in the IC guiding groove 10 to move linearly. The linear vibrator 20 pushes the IC in the IC guiding groove 10 forward through the vibration force to realize the continuous conveying of the IC. The linear vibrator 20 has the characteristics of high transmission efficiency, simple structure, convenient maintenance, etc., and is therefore widely used in the field of material conveying.

[0041] The IC tube loading mechanism includes a telescopic cylinder 30, a limiting device 40, and a plurality of stacked IC tubes. The limiting device 40 is used to limit the plurality of stacked IC tubes. The plurality of stacked IC tubes will slide down due to the action of gravity. The telescopic cylinder 30 is used to drive the support plate to extend to support the target IC tube 50 when the target IC tube 50 descends to the same height as the IC guiding groove 10, so as to cooperate with the IC ejecting mechanism to eject the IC in the target IC tube 50 into the IC guiding groove 10. The IC ejecting mechanism includes a coil spring 60 and a stepping motor 70. The stepping motor 70 is used to drive the coil spring 60 to unwind, so that the free end of the coil spring 60 extends into the target IC tube 50 to eject the IC in the target IC tube 50 into the IC guiding groove 10. The coil spring 60 can be extended and retracted through the free end, and has the advantages of small occupied space and convenient use.

[0042] The above IC feeder includes an IC loading mechanism, an IC ejecting mechanism, and an IC tube loading mechanism disposed between the IC loading mechanism and the IC ejecting mechanism. The IC loading mechanism includes an IC guiding groove and a linear vibrator installed on the IC guiding groove. The IC guiding groove is used to guide the IC, and the linear vibrator is used to drive the IC in the IC guiding groove to move linearly. The IC tube loading mechanism includes a telescopic cylinder, a limiting device, and a plurality of stacked IC tubes. The limiting device is used to limit the plurality of stacked IC tubes. The telescopic cylinder is used to drive a support plate (not shown) to extend to support the target IC tube when the target IC tube descends to the same height as the IC guiding groove, so as to cooperate with the IC ejecting mechanism to eject the IC in the target IC tube into the IC guiding groove. The IC ejecting mechanism includes a coil spring and a stepping motor. The stepping motor is used to drive the coil spring to unwind, so that the free end of the coil spring extends into the target IC tube to eject the IC in the target IC tube into the IC guiding groove. When the above IC feeder works, the stepping motor can drive the coil spring to eject the IC in the target IC tube into the IC guiding groove, and perform automatic IC loading through the cooperation of the IC guiding groove and the linear vibrator. Through the mutual cooperation of the stepping motor, the coil spring, the IC guiding groove, and the linear vibrator, the IC in the target IC tube can be automatically loaded, improving the IC loading efficiency and meeting the manufacturing requirements of integrated circuits.

[0043] Wherein, the IC feeder further includes an IC tube unloading mechanism. The IC tube unloading mechanism is disposed below the IC tube loading mechanism. The IC tube unloading mechanism includes an IC tube unloading chute 80. The telescopic cylinder 30 is further used to drive the support plate to retract to release the target IC tube 50 when all the ICs in the target IC tube 50 are ejected, so that the target IC tube 50 falls into the IC tube unloading chute 80. Through the mutual cooperation of the IC tube unloading chute 80 and the telescopic cylinder 30, the target IC tube 50 in the empty tube state can be automatically unloaded, facilitating the maintenance of the operation and maintenance personnel.

[0044] Furthermore, the IC tube loading mechanism further includes a positioning cylinder (not shown). The IC tube loading mechanism completes the loading of the IC tube through the cooperation of the positioning cylinder and the telescopic cylinder 30. The positioning cylinder is installed above the telescopic cylinder 30. When the target IC tube 50 descends to the same height as the IC guiding groove 10, the IC tube located above and adjacent to the target IC tube 50 (i.e., the adjacent IC tube) is at the same height as the positioning cylinder. The positioning cylinder drives the positioning column to extend to position the adjacent IC tube and prevent the adjacent IC tube from interfering with the target IC tube 50. After all the ICs in the target IC tube 50 are ejected, the telescopic cylinder 30 first drives the support plate to retract to release the target IC tube 50, and then drives the support plate to extend to cooperate with the descent of the adjacent IC tube. After the telescopic cylinder 30 drives the support plate to extend, the positioning cylinder drives the positioning column to retract to release the adjacent IC tube. Through the cooperation of the positioning cylinder and the telescopic cylinder 30, the operation of the IC tube loading mechanism is made more stable.

[0045] Among them, the limiting device 40 is installed at both ends of the stacked IC tubes. The limiting device 40 includes a first limiting plate 41, a second limiting plate 42 and a third limiting plate 43. The third limiting plate 43 is fixedly installed on the first limiting plate 41, and the second limiting plate 42 is slidably installed on the first limiting plate 41. The end of the IC tube is arranged between the second limiting plate 42 and the third limiting plate 43. Through the mutual cooperation of the second limiting plate 42 and the third limiting plate 43, the end of the IC tube can be limited, thereby limiting a plurality of stacked IC tubes.

[0046] Among them, the limiting device 40 further includes a width adjustment screw 44. The width adjustment screw 44 is used to adjust the sliding distance of the second limiting plate 42 so as to adjust the distance between the second limiting plate 42 and the third limiting plate 43. The first limiting plate 41 and the second limiting plate 42 are respectively formed with a first adjustment hole 411 and a second adjustment hole 421 for cooperating with the width adjustment screw 44. The width adjustment screw 44 sequentially passes through the first adjustment hole 411 and the second adjustment hole 421. Since the widths of different specifications of IC tubes are different, adjusting the distance between the second limiting plate 42 and the third limiting plate 43 by the width adjustment screw 44 can meet the limitation of IC tubes with different widths.

[0047] Furthermore, the limiting device 40 at one end of the stacked IC tubes is installed on a length adjustment plate (not shown). The distance between the limiting devices 40 at both ends of the IC tube can be adjusted through the length adjustment plate. Since the lengths of different specifications of IC tubes are different, adjusting the distance between the limiting devices 40 at both ends of the IC tube can meet the limitation of IC tubes with different lengths.

[0048] Among them, a stabilizing block 412 is fixedly installed on the first limiting plate 41. A butting spring 413 is installed between the stabilizing block 412 and the second limiting plate 42. A first butting hole 4121 and a second butting hole 422 for cooperating with the butting spring 413 are respectively provided on the stabilizing block 412 and the second limiting plate 42. Through the mutual cooperation of the stabilizing block 412, the butting spring 413 and the second limiting plate 42, the second limiting plate 42 can slide smoothly on the first limiting plate 41, improving the sliding stability of the second limiting plate 42. Further, the stabilizing block 412 is respectively arranged above and below the width adjusting screw 44, making the force on the second limiting plate 42 more uniform.

[0049] Among them, a locking block 414 is fixedly installed on the first limiting plate 41. The locking block 414 is used to lock the second limiting plate 42 on the first limiting plate 41 after the width adjusting screw 44 is adjusted. By locking the second limiting plate 42 on the first limiting plate 41 through the locking block 414, during the operation of the IC feeder, the second limiting plate 42 will not generate sliding displacement, thereby improving the working stability of the IC feeder.

[0050] Among them, the IC ejection mechanism further includes a driving gear 71, a transmission belt 72, a driven gear 73, a driving friction wheel 74 and a driven friction wheel 75. The output shaft of the stepping motor 70 is connected to the driving gear 71. The driving gear 71 is connected to the driven gear 73 through the transmission belt 72. The driven gear 73 is connected to the driving friction wheel 74 through a transmission shaft. The free end of the coil spring 60 is arranged between the driving friction wheel 74 and the driven friction wheel 75. Through the mutual cooperation of the stepping motor 70, the driving gear 71, the transmission belt 72, the driven gear 73, the driving friction wheel 74 and the driven friction wheel 75, the stepping motor 70 can stably drive the free end of the coil spring 60 to extend and retract, so as to cooperate to eject the IC in the target IC tube 50 into the IC guiding groove 10.

[0051] Further, the IC ejection mechanism further includes a tensioning wheel 76. The tensioning wheel 76 is used to press on the surface of the transmission belt 72 to tension the transmission belt 72. Through the tensioning wheel 76, the transmission belt 72 is always in a tensioned state, so that the extension and retraction of the free end of the coil spring 60 are more stable.

[0052] Further, the IC tube feeding mechanism further includes a solenoid valve 90. The solenoid valve 90 is electrically connected to the telescopic cylinder 30 and is used to control the telescopic cylinder 30. By controlling the telescopic cylinder 30 through the solenoid valve 90, the operation of the telescopic cylinder 30 is more stable.

[0053] Further, the IC feeder further includes a support mechanism, and the support mechanism includes support legs 81. The support legs 81 are installed below the IC loading mechanism, the IC ejecting mechanism, and the IC tube loading mechanism, and are used to support the IC loading mechanism, the IC ejecting mechanism, and the IC tube loading mechanism. Through the supporting effect of the support legs 81, the structure of the IC feeder is made more stable.

[0054] The present utility model also discloses an IC inserter, and the IC inserter includes the above-mentioned IC feeder. By including the above-mentioned IC feeder, the IC inserter can automatically load the ICs in the target IC tube, improve the IC loading efficiency, and meet the manufacturing requirements of integrated circuits.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0056] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
