Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitor production and processing equipment, in particular to a discharging mechanism of a capacitor forming machine. Background Art
[0002] Tantalum capacitor is a capacitor whose dielectric is tantalum metal oxide. Tantalum capacitors have the advantages of high capacity density, high stability, low ESR (equivalent series resistance), low leakage current, etc., and are widely used in electronic products, especially in circuits with high performance and high stability requirements, such as communication equipment, computers, medical equipment and other fields. Common tantalum capacitors can be divided into direct plug-in type and surface mount type according to the way they are used. They are mainly selected according to the size and space of the installed product. Surface mount tantalum capacitors are more used in mobile phones, new energy vehicle processing and other fields.
[0003] SMD tantalum capacitors generally include a capacitor body and pins at both ends of the capacitor body. In order to protect the capacitor components during the processing, the capacitor components are usually fixed on a strip lead frame to form a strip capacitor raw material. The capacitor components on the lead frame are cut and bent during the processing. Therefore, the existing processing equipment often uses a straight-line conveying method to cut and bend during the trimming process. This method requires the processing equipment to be placed in a straight line. After the capacitor components are bent, the material is usually discharged by setting a clamping manipulator or adding an additional conveying rail to transfer the processed capacitor components to the inspection station or packaging station. The manipulator needs to be lifted, transferred, opened and closed intermittently and multiple times. On the one hand, this design has a long processing production line and occupies a large area, which is not conducive to the miniaturization of equipment and increases the cost of production equipment. On the other hand, it is difficult to link the various processes, which also reduces the overall discharge efficiency and is not conducive to the development of high-speed processing.
[0004] Therefore, further research and development is needed to solve the above-mentioned technical problems in the prior art. Utility Model Content

[0029] In order to facilitate the understanding of the utility model, the technical solutions and advantages of the utility model are further described in detail below in conjunction with the accompanying drawings and embodiments. The specific structure and characteristics are described below in an exemplary manner, which should not constitute any limitation to the utility model. At the same time, any of the technical features mentioned below (including implicit or disclosed), as well as any technical features directly displayed or implied in the figure, can continue to be arbitrarily combined or deleted between these technical features, so as to form more other embodiments that may not be directly or indirectly mentioned in the utility model. The preferred implementation of the utility model is given in the accompanying drawings. However, the utility model can be implemented in many different forms and is not limited to the implementation described herein. On the contrary, the purpose of providing these implementations is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
[0030] like Figure 1-7 As shown, the utility model provides a discharging mechanism of a capacitor forming machine 10, which is used to sort good or bad capacitor elements 20 after bending and discharging; the capacitor element 20 includes a body 201 and pins 202 located at both ends of the body 201; the capacitor element 20 is bent and formed as shown in FIG. Figure 2 As shown; the capacitor forming machine 10 includes a frame 101 and an adsorption turntable 102 rotatably arranged on the frame, a plurality of capacitor limit parts 1021 for placing capacitor elements 20 are spaced apart on the outer peripheral side wall surface of the adsorption turntable 102, an air channel (not shown) in the prior art is arranged inside the adsorption turntable, and an air suction hole connected to the air channel is arranged on the capacitor limit part 1021, and the capacitor element 20 is adsorbed on the capacitor limit part 1021 through an external air source, and flows to the discharging mechanism as the adsorption turntable rotates;
[0031] The discharging mechanism includes a probe detection device 1, a good product discharging device 2, and a defective product discharging device 3 which are arranged in sequence along the circumference of the adsorption turntable; the probe detection device 2 can be driven by power to reciprocate in the direction of approaching or moving away from the capacitor element 20 on the adsorption turntable 101, so as to contact the pin 202 of the capacitor element 20 and complete the detection; the good product discharging device 2 and the defective product discharging device 3 are respectively used to blow the good capacitor elements and the defective capacitor elements detected and screened by the probe detection device 1 away from the capacitor limit part and complete the storage; further, the capacitor forming machine also includes a control module 4, which is used to receive the signal of the probe detection device 1, judge and control the operation of the first blowing device 22 and the second blowing device 32.
[0032] In this embodiment, the structure and setting method of the discharge mechanism are optimized, and the discharge structure and the adsorption turntable are well linked. The capacitor element after cutting is fixed tightly on the side of the adsorption turntable by adsorption, and the bending forming process, the detection process and the material separation process are completed simultaneously. Finally, the good capacitor element or the defective capacitor element on the capacitor limit part is blown into the corresponding placement box by the first blowing device and the second blowing device arranged above the adsorption turntable to complete the discharge. In this process, there is no need to transfer the capacitor element, and the overall action is continuous and non-stop, thereby ensuring the processing and discharge efficiency. There is also no need to add gripping components such as manipulators that need to be lifted, transferred, opened and closed. The capacitor element can be separated from the adsorption turntable by an air nozzle, which makes the equipment structure simpler, occupies a smaller area, and consumes less energy.
[0033] To be further detailed, the good product discharging device 2 and the defective product discharging device 3 respectively include a good product placement box 21 and a defective product placement box 31 adjacently arranged below the adsorption turntable; the frame 101 is respectively provided with a first blowing device 22 for blowing the good capacitor elements on the capacitor limiting part 1021 downward into the good product placement box, and a second blowing device 32 for blowing the defective capacitor elements on the capacitor limiting part 1021 downward into the defective product placement box. To further refine, the first blowing device 22 and the second blowing device 32 respectively include a first air nozzle 221 and a second air nozzle 321 connected to an external air source; the first air nozzle 221 and the second air nozzle 321 are respectively installed on the frame 101 through a first mounting seat 222 and a second mounting seat 322, and are located above the capacitor limiting portion 1021, and the first air nozzle 221 and the second air nozzle 321 respectively blow downwards to make the good capacitor element and the defective capacitor element fall into the good product placement box 21 and the defective product placement box 31, respectively.
[0034] In this embodiment, the air channel setting of the adsorption turntable is not elaborated. The entire turntable can be provided with a negative pressure chamber, and its adsorption force can be adjusted to drive the capacitor element to rotate and prevent the capacitor element from falling, and to meet the blowing and discharging operation of the first blowing device or the second blowing device. It is also possible that the suction holes of each capacitor limit part are individually connected to the air source through an airflow duct and form a signal connection with the control module. When the capacitor element is good or defective, the suction hole closing operation is carried out under the control of the control module, so that the first blowing device or the second blowing device can complete the blowing of the capacitor element with a smaller blowing volume. There is no specific limitation on this, as long as it can meet the beneficial effects of the utility model, it can be implemented.
[0035] In order to make the capacitor elements blown into the good product placement box or the defective product placement box more accurately and prevent the capacitor elements from falling out of the placement box, preferably, the tops of the good product placement box and the defective product placement box are respectively inclined to provide a first guide channel 23 and a second guide channel 33 for guiding the good capacitor elements and the defective capacitor elements into the good product placement box 21 and the defective product placement box 31.
[0036] Preferably, the probe detection device 1 includes a detection probe 11 and a detection drive device 12 for driving the detection probe 11 to reciprocate in the direction of approaching or moving away from the capacitive element on the adsorption turntable. Specifically, the detection probe is a metal probe, and two detection probes are respectively set corresponding to the two pins. In this embodiment, the capacitance detection includes electrical detection such as detecting whether the capacitor pin is short-circuited or leaking by the probe. The detection probe is a detection probe in the prior art, and its setting form, structure, and detection principle can refer to the prior art; its signal feedback and control module judgment process can refer to the following, that is, it will detect the signal and feedback to the control module, through the cooperation of the control module and the servo motor, record the position of the detected capacitive element on the adsorption turntable, and through the detection station and the set position of the first blowing device and the second blowing device, judge the angle of rotation of the adsorption turntable, etc., determine whether to start the first blowing device or the second blowing device, so as to complete the signal transmission. The above signal feedback process is only used as an example, and the utility model only involves the components, structure, and setting form of the discharge. It should be noted that the circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.
[0037] Preferably, the detection probe 11 is slidably arranged on the frame 101 through the detection slide 13, and the detection drive device 12 is a cam swing transmission device. The cam swing transmission device is a cam swing transmission device in the prior art, which makes the swing rod move linearly through the contact between the rotating cam and the swing rod. Its structure and setting form can refer to the prior art. In this embodiment, the detection probe is driven to move back and forth in the form of a cam swing transmission. On the one hand, the structural setting of the cylinder and the like is reduced. On the other hand, the cam can be driven by a servo motor. When the demand for controlling the discharge control is met, the rotation of the cam can be driven by the same servo motor as the adsorption turntable, so as to better link the detection mechanism with the adsorption turntable. In other optional embodiments, a transmission method such as a connecting rod can also be used.
[0038] It should be noted that, in addition to the above scheme, the present invention also includes other control modules, electrical components, etc. that meet the function of the discharge mechanism of the capacitor forming machine, which will not be described in detail in the present invention. In addition, a strip capacitor raw material (i.e., the raw material after the capacitor element is fixed on the lead frame) feeding mechanism 103 is set before the discharge mechanism, a cutting mechanism 104 that cuts the capacitor element from the strip capacitor raw material and pushes it horizontally to the adsorption turntable, and a capacitor element (such as Figure 1 ) for bending (such as Figure 2 The bending mechanism 105 (shown) will not be described in detail in the present invention.
[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. For ordinary technicians in this field, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
