Description

Technical Field

[0001] This utility model relates to the field of capacitor production equipment, specifically to a capacitor laser marking and appearance inspection device. Background Technology

[0002] Capacitors are commonly used electronic components in circuits. The capacitor's casing usually needs to be marked with capacitance, voltage, safety certification marks, or other relevant information to help users select and use capacitors that meet circuit requirements and safety standards. Marking on the capacitor casing can be done using laser marking, which offers advantages such as high efficiency and clear markings. After laser marking, the capacitor's appearance still needs to be inspected to avoid unclear markings or other contaminants on the casing. Currently, capacitor marking production lines are long and space-consuming, which is not conducive to space saving. Furthermore, post-marking visual inspection is usually done manually, which is inefficient and prone to errors. Utility Model Content

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0026] like Figures 1 to 7 As shown, the capacitor laser marking and appearance inspection device provided by this utility model is used for automatic marking and appearance inspection of the outer shell 110 of capacitor 100. The device mainly includes a feeding mechanism 200, a rotation transmission mechanism 300, a first laser marking mechanism 400, a second laser marking mechanism 500, a shooting mechanism 600, and a unloading mechanism 700.

[0027] The rotating transmission mechanism 300 includes a turntable 310 and at least one first clamp 320 mounted on the turntable 310. The turntable 310 is rotatable, for example, driven by a motor, thereby causing the first clamp 320 to sequentially pass through a loading station 311, a marking station 313, a photographing station 314, and a unloading station 315 within one revolution of the turntable 310. These stations are respectively used to receive the capacitor 100, perform the first marking on the capacitor 100, perform the second marking on the capacitor 100, inspect the appearance of the capacitor 100's casing, and transfer the capacitor 100 to the next process. Using the turntable 310 to drive the first clamp 320 through multiple stations in the circumferential direction helps to reduce the footprint of the device, making the device more compact. The first clamp 320 is used to loosen or clamp the leads 120 of the capacitor 100. When the first clamp 320 clamps the leads 120 of the capacitor 100, the outer casing 110 of the capacitor 100 is located outside the first clamp 320, which facilitates the processing of the outer casing 110 of the capacitor 100. When the first clamp 320 loosens the leads 120 of the capacitor 100, the capacitor 100 leaves the first clamp 320 and is unloaded from the device. The loading mechanism 200 is used to move the capacitor 100 to the loading station 311, providing convenience for the first clamp 320 located at the loading station 311 to clamp the leads 120 of the capacitor 100. A first laser marking mechanism 400 faces the marking station 313 and is used to mark the first side 111 of the outer casing 110 of the capacitor 100. A second laser marking mechanism 500 faces the marking station 313 and is used to mark the second side 112 of the outer casing 110 of the capacitor 100, thereby achieving marking on both sides of the outer casing 110 of the capacitor 100. An imaging mechanism 600 faces the imaging station 314 and is used to photograph multiple sides of the capacitor 100, including at least the first side 111 and the second side 112. The imaging mechanism 600 can at least capture the marking appearance of the first side 111 and the second side 112. A feeding mechanism 700 is used to move the capacitor 100 on the feeding station 315 of the laser marking device to the next process.

[0028] The loading mechanism 200 includes a loading conveyor channel, which is used to transport the capacitors 100 one by one to the loading station 311 for easy marking of the outer casing 110 of each capacitor 100. The loading conveyor channel includes a conveyor belt 210, which can be driven by a motor to rotate cyclically. The capacitors 100 are transported on the conveyor belt 210 with their leads 120 facing upwards, so that the loading mechanism 200 can move the capacitors 100 to the first clamp 320 and clamp the leads 120 of the capacitors 100.

[0029] The feeding and conveying channel also includes a pin centering mechanism 240 disposed on the conveyor belt 210. The pin centering mechanism 240 includes a housing clamping mechanism 241 and a pin straightening mechanism 242 located on the housing clamping mechanism 241. The housing clamping mechanism 241 is used to clamp the housing 110 of the capacitor 100, and the pin straightening mechanism 242 is used to straighten the pins 120, so that the plane on which the two pins 120 are located is parallel to the first side 111. The pin centering mechanism 240 is used to adjust the pins 120 of the capacitor 100 to prevent the pins 120 from bending relative to the first side 111 and affecting the marking.

[0030] In some examples, the loading mechanism 200 is located below the loading station 311, which may be located at the lower end of the turntable 310 for easy bottom-up material handling. The loading mechanism 200 includes a lifting device 220 and a second clamp 230. The second clamp 230 is disposed on the lifting device 220, which drives the second clamp 230 to move between the loading station 311 and the end of the conveyor belt 210. For example, the lifting device 220 can drive the second clamp 230 to move up and down. The second clamp 230 is used to release or clamp the housing 110 of the capacitor 100. When the second clamp 230 moves to the loading station 311, the lead 120 of the capacitor 100 extends into the first clamp 320, the first clamp 320 clamps the lead 120, and the second clamp 230 releases the housing 110, thereby loading the capacitor 100 onto the second rotary transmission mechanism 300.

[0031] In some examples, the opening or closing direction of the first clamp 320 is parallel to the axial direction of the turntable 310, which refers to the direction of rotation of the turntable 310 around its axis. When the first clamp 320 clamps the pins 120 of the capacitor 100, the plane containing the two pins 120 of the capacitor 100 is perpendicular to the axial direction of the turntable 310, that is, the plane containing the two pins 120 of the capacitor 100 is parallel to the surface of the turntable 310. The first side surface 111 is parallel to the plane containing the two pins 120. The first side surface 111 has a larger area. The first laser marking mechanism 400 includes a first laser emitter 410, the orientation of which is parallel to the axial direction of the turntable 310, thereby enabling the first laser emitter 410 to mark the larger area of ​​the first side surface 111. The first laser marking mechanism 400 may also include a first position adjustment mechanism, the first laser emitter 410 being connected to the first position adjustment mechanism, which is used to adjust the position of the first laser emitter 410 relative to the marking station 313.

[0032] In some examples, the second laser marking mechanism 500 includes a third clamp 510 and a second laser emitter 520. The third clamp 510 is used to clamp or release two sides of the capacitor 100 parallel to the plane containing the two leads 120 of the capacitor 100, including a first side 111. The second side 112 is opposite to the two leads 120 of the capacitor 100. The second side 112 has a smaller area, and clamping the capacitor 100 with the third clamp 510 facilitates precise marking on the smaller second side 112. The orientation of the second laser emitter 520 is perpendicular to the axis of the turntable 310, thereby marking the second side 112. The second laser marking mechanism 500 may also include a second position adjustment mechanism, to which the second laser emitter 520 is connected. The second position adjustment mechanism is used to adjust the position of the second laser emitter 520 relative to the marking station 313.

[0033] In some examples, the imaging mechanism 600 includes a first camera 610, a second camera 620, a third camera 630, a fourth camera 640, and a fifth camera 650. These five cameras are used to photograph the five sides of the capacitor 100's casing 110, excluding the side from which the leads 120 extend. The casing 110 can be a cuboid. The five cameras can detect markings and contamination on multiple sides of the casing 110. The first camera 610 and the second camera 620 face two sides of the capacitor 100 parallel to the plane containing the two leads 120, one of which is the first side 111. The third camera 630 and the fourth camera 640 face two sides of the capacitor 100 perpendicular to the plane containing the two leads 120, respectively. The fifth camera 650 faces the second side 112.

[0034] In some examples, the unloading mechanism 700 includes a fourth clamp 710 and a translation mechanism 720. The fourth clamp 710 is used to clamp or release the casing 110 of the capacitor 100. The fourth clamp 710 is connected to the translation mechanism 720, which is used to move the fourth clamp 710 between the unloading station 315 and the unloading station. For example, the translation mechanism 720 can move the fourth clamp 710 horizontally. The fourth clamp 710 can hold the portion of the casing 110 of the capacitor 100 near the pin 120, facilitating subsequent clamping of the capacitor 100 by the fixtures in the process.

[0035] In some examples, the device also includes a waste collection mechanism 800, which may include, for example, a waste collection funnel. The waste collection mechanism 800 is located below the unloading station 315 or the unloading mechanism 700. When the appearance of the capacitor 100 captured in the imaging mechanism 600 does not meet the requirements, the capacitor 100 rotates with the turntable 310 to the unloading station 315, the first clamp 320 releases the leads 120 of the capacitor 100, the fourth clamp 710 does not clamp the capacitor 100, and the defective capacitor 100 falls into the waste collection mechanism 800.

[0036] In some examples, the device also includes an image display 810 for displaying images taken by the imaging mechanism 600, allowing the operator to visually understand the appearance of the capacitor 100.

[0037] In some examples, the device also includes a laser display 820, which is electrically connected to the first laser marking mechanism 400 and the second laser marking mechanism 500, respectively, for displaying the working status of the first laser marking mechanism 400 and the second laser marking mechanism 500.

[0038] In some examples, the first clamp 320 includes two relatively movable clamping plates 321 and a rocker arm 322 connected to at least one clamping plate 321, the rocker arm 322 being closer to the axis of the turntable 310 relative to the clamping plates 321. The two relatively movable clamping plates 321 can be connected by an elastic element such as a spring, so that when the rocker arm 322 is not subjected to external force, the two clamping plates 321 are clamped together, and when the rocker arm 322 is subjected to external force, the two clamping plates 321 can overcome the elastic force and open. The laser marking device also includes a pressure plate 900, which can move closer to or further away from the turntable 310. When the clamp 320 is located at the loading station 311 or the unloading station 315, the pressure plate 900 is located outside the swing arm 322. At this time, the pressure plate 900 can move closer to the turntable 310 and press against the swing arm 322. The swing arm 322 swings, causing the two clamping plates 321 to move away from each other, thereby releasing the first clamp 320 on the loading station 311 to prepare for clamping the capacitor 100. At the same time, it releases the first clamp 320 on the unloading station 315, realizing the transfer of the capacitor 100 or the disposal of waste. Then, the pressure plate 900 moves away from the turntable 310, causing the first clamp 320 on the receiving station to clamp the capacitor 100. Using a single pressure plate 900 to adjust the tension of the first clamp 320 on two stations simplifies the equipment components and operation control.

[0039] In some examples, the device also includes a power system comprising a main motor 330, an upper rotating shaft 331, a lower rotating shaft 332, and multiple different cam mechanisms 333. The main motor 330 is driven by the lower rotating shaft 332, for example, via a sprocket or pulley, and the lower rotating shaft 332 and the upper rotating shaft 331 are driven by the same means, for example, via sprockets or pulleys. The rotation transmission mechanism 300 also includes a divider, to which a turntable 310 is connected. The divider is driven by the upper rotating shaft 331, for example, via a pulley. Each cam mechanism 333 includes a cam 334 disposed on the upper rotating shaft 331 or the lower rotating shaft 332 and a connecting rod 335 connected to the cam 334. The cam 334 of each cam mechanism 333 is different, for example, the diameter of the cam 334 is different or the connecting rod 335 is different, so that the actions or action times of the mechanism driven by the different cam mechanisms 333 are different. The lifting device 220, the fourth clamp 710, the translation mechanism 720, and the pressure plate 900 are respectively connected to the ends of the connecting rods 335 of different cam mechanisms 333. This structure allows one motor to simultaneously drive the turntable and multiple mechanisms, saving energy and simplifying the structure and control software.

[0040] In some examples, the fourth clamp 710 in the unloading mechanism 700 is driven by a third rocker arm to open and close the two third clamping plates of the fourth clamp 710. The end of the connecting rod 335 of a cam mechanism 333 is connected to the first sliding block, causing the first sliding block to move toward or away from the third rocker arm, thereby causing the fourth clamp 710 to open and close. The translation mechanism 720 in the unloading mechanism 700 includes a slide rail and a second sliding block that cooperates with the slide rail. The fourth clamp 710 is connected to the second sliding block, which is connected to the end of the connecting rod 335 of another cam mechanism 333. The cam 333 of the cam mechanism 333 may have a laterally curved groove on its circumferential surface. One end of the connecting rod 335 moves within the groove, thereby causing the end of the connecting rod 335 to drive the second sliding block to move laterally.

[0041] In some examples, the housing clamping mechanism 241, the pin clamping mechanism 242, the second clamp 230, and the third clamp 510 are each driven by an independent cylinder.

[0042] In some examples, there are eight first fixtures 320 arranged circumferentially along the turntable 310. When one first fixture 320 is located at the loading station 311, there is one first fixture 320 at each of the marking station 313, the shooting station 314, and the unloading station 315. Multiple first fixtures 320 complete their respective processes at their respective stations, improving production efficiency. There can be empty stations 312 between adjacent stations in the loading station 311, marking station 313, shooting station 314, and unloading station 315, facilitating the arrangement of stations and mechanisms and allowing for better coordination with the time intervals of mechanism actions.

[0043] Finally, it should be emphasized that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
