DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Please refer to Figures 1 to 9 , the present application provides a kind of integrated circuit board pin cutting device, comprising:

[0029] ​​​​A guide rail system 1 and a resector and a collection object 3 thereon, with a collection box 4 being provided below the collection object 3; a collection camera 8 being installed on the inner bottom of the collection box 4, and two rotatable guide plates 7 being slidably installed on the inner bottom of the collection box 4, and the two guide plates 7 being symmetrically arranged; when the free ends of the two guide plates 7 are in contact with each other, a protective space can be formed between the two guide plates 7 and the collection box 4, and the two guide plates 7 are in an inclined state; when the free ends of the two guide plates 7 are away from each other, the guide plates 7 are in an expanded and expanded state; and a driver is included for controlling the free ends of the two guide plates 7 to move closer to or away from each other.

[0030] In order to prevent the falling weld leg excision from scratching the collection camera 8 below, affecting the normal operation of the visual system, and avoiding misjudgment, the present invention provides two rotatable guide plates 7, and enables the two guide plates 7 to move relative to each other under the control of the driver, thereby forming two states. First, when cutting the weld leg, a protective space is formed between the two guide plates 7 and the inner wall of the collection box 4, thereby protecting the collection camera 8 inside it. When visual collection is required, the free ends of the two guide plates 7 are moved away from each other, so that the two are in an expanded state, thereby avoiding interference with the visual collection range of the collection camera 8. In the cutting process, the falling weld leg excision will hit the outer wall of the guide plate 7 in an inclined state, thereby slowing down the falling impulse of the weld leg excision and gathering it on both sides of the protective space.

[0031] In one of the more preferred embodiments, the outer wall of the collection box 4 opposite to the inclined surface of the guide plate 7 is provided with a plurality of air inlet ducts 6, the output direction of the air inlet ducts 6 is toward the lowest point of the inclined surface of the guide plate 7, and the air volume input into the collection box 4 by the air inlet ducts 6 will form an upward ascending airflow on the inclined surface of the guide plate 7, outputting wind force to the bottom of the collection object 3, please refer to Figures 3 to 5 In the process of cutting the weld foot, the cut pieces are large and small. Some of the smaller cut pieces or other impurities will remain at the bottom of the collection object 3. By blowing parallel airflow to the inclined outer walls of the two guide plates 7 in the protective space, due to the inclined state of the guide plates 7, the airflow will form an upward inclined rising airflow along its outer wall when it is blocked by the guide plates 7, thereby cleaning the bottom of the collection object 3 by wind. Secondly, after a certain degree of cleaning is completed, the two guide plates 7 are controlled by the driver to release the protective space. At this time, the two guide plates 7 will gradually transform from an inclined state to a vertical state. At this time, the guide plates 7 are still inclined. At this time, the entire lower surface of the collection object 3 can be cleaned by the swinging change of the guide plates 7, thereby improving the cleaning quality and range.

[0032] The air inlet duct 6 needs to be connected to an external air source, and a blower pump can be used.

[0033] Further, since the acquisition camera 8 is at the inner bottom of the acquisition box 4, the lighting conditions will be affected, thereby affecting the acquisition ability of the vision system, therefore, the embodiment designs light compensation, the outer wall opposite to the two flow guides 7 is provided with a reflector 9, and the outer wall of the flow guide 7 below the reflector 9 is also fixedly provided with a light source 11, when the two flow guides 7 are in the flared and expanded state, the light emitted by the two light sources 11 is staggered and irradiates the surface of the reflector 9 opposite to it, and the reflector 9 reflects the light to the bottom of the acquisition object 3, please refer to Figure 3 、 Figure 5 、 Figure 8 and Figure 9 , which shows two states of the flow guide 7, when in the flared and expanded state, the light generated by the light source 11 can be just irradiated to the reflector 9 opposite to it, due to the principle of mirror reflection, the light generated by the light source 11 can be reflected to the bottom of the acquisition object 3, thereby light compensation is carried out for the image acquisition environment of the acquisition camera 8.

[0034] In a more preferred embodiment, the driver includes a mounting groove 14 embedded on the outer wall of the acquisition box 4, the mounting groove 14 is provided with a guide groove 15 near the inside of the flow guide 7, a sliding block is slidingly installed in the guide groove 15, a rotating shaft is rotatably installed on the sliding block, the flow guide 7 is rotatably installed on the sliding block through the rotating shaft, a gear 16 is fixedly installed on the outer wall of the inside of the mounting groove 14 extending to the rotating shaft, a rack 17 is fixedly installed on the inner top of the guide groove 15, the gear 16 is engaged with the rack 17, and the inner bottom of the acquisition box 4 is also provided with an electric telescopic rod for controlling the displacement of the sliding block, please refer to Figure 3 、 Figure 5 and Figure 7 , by providing the mounting groove 14, the gear 16 and the rack 17 can be built-in, secondly, by the limiting relationship between the guide groove 15 and the sliding block, the whole flow guide 7 can be slidingly installed on the inner bottom of the acquisition box 4, and then by the rotation of the rotating shaft, when the flow guide 7 approaches the acquisition camera 8, the free end of the flow guide 7 will rotate, that is, the bottom of the flow guide 7 can approach the acquisition camera 8 while rotating, so that the two flow guides 7 are surrounded on both sides of the acquisition camera 8, thereby forming the maximum flared and expanded state, and the retained cutting objects on the outer wall of the flow guide 7 can be cleaned more quickly.

[0035] In a more preferred embodiment, please refer to Figure 1 , the guide rail system 1 is slidingly provided with a clamping tool 12, the acquisition object 3 is embeddedly installed in the inside of the clamping tool 12, the top of the acquisition box 4 and the below of the clamping tool 12 are designed with a cutting gap, a cutter is slidingly installed on the guide rail system 1, and the output end of the cutter is provided with a cutting disc 2, and the cutting disc 2 and the cutter can operate to the cutting gap and cut the welding feet at the bottom of the acquisition object 3.

[0036] Furthermore, when the two guide plates 7 are in the expanded and unfolded state, the angle formed between the two does not exceed ninety degrees. By limiting the maximum expanded and unfolded angle of the two guide plates 7, the illumination range can better cover the bottom of the collection object 3, avoiding the incident angle of the light source 11 being too large, resulting in an excessively large reflection angle and thus offsetting the illumination range.

[0037] Furthermore, the outer walls of the two guide plates 7 on the opposite sides are coated with a scratch-resistant coating to prevent the outer walls of the guide plates 7 from being excessively damaged by objects with sharp points.

[0038] Furthermore, a plurality of discharge chutes 13 are installed on the inner bottom of the collection box 4. The discharge chutes 13 are in the form of long slots and are evenly distributed, so as to facilitate the collection of the excised material and transfer it out of the inner bottom of the collection box 4.

[0039] The present invention utilizes the fitting and unfolding of the guide plate 7 to not only protect the acquisition camera 8 but also clean and fill in the light on the bottom of the acquisition object 3, thereby improving the quality of visual acquisition.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the conventional means mature in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
