Description

Technical Field

[0001] The utility model belongs to the technical field of capacitors, and in particular relates to a capacitance detection device. Background Art

[0002] Capacitors are electronic components that store electric charge. Capacitors are made of two tightly packed conductors (usually plates) separated by a dielectric material. When the plates are connected to a power source, they accumulate charge, with one plate accumulating positive charge and the other plate accumulating negative charge. With the rapid development of electronic information technology, the replacement speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat-screen TVs (LCD and PDP), laptops, digital cameras, etc., continue to grow, driving the growth of the capacitor industry.

[0003] In the production of capacitors, it is usually necessary to use a detection device to detect the stiffness of its pin solder joints and test their fixation firmness on the solder feet. The strength test of traditional pin solder joints generally adopts a random inspection method, and the pins are manually bent. This makes the inspection operation more labor-intensive and time-consuming, and inefficient. Moreover, because it is a random inspection method, it is impossible to achieve 100% inspection, making its test results inaccurate and unable to guarantee its pass rate.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] See also Figures 1-6 As shown, the utility model is a capacitance detection device, comprising an L-shaped base 1, on which a feeding assembly 2 and a storage assembly 3 are mounted. An electric push rod 4 is mounted at one end of the L-shaped base 1, and a plurality of clamping assemblies 5 are mounted on the feeding assembly 2. The storage assembly 3 is used to store a plurality of capacitors 6. A detection assembly 7 is mounted on the electric push rod 4, and a pressure sensor 8 is mounted on the detection assembly 7. There are two pressure sensors 8.

[0030] The loading component 2 is used to individually convey the capacitor 6 installed on the storage component 3. The clamping component 5 can fix the capacitor 6 conveyed on the loading component 2. The electric push rod 4 can drive the detection component 7 to approach the capacitor 6 on the loading component 2 to detect whether the pin solder joint strength of the capacitor 6 is qualified through the pressure sensor 8.

[0031] In actual use, several capacitors 6 are pre-placed on the storage component 3, and the capacitors 6 are transported individually by rotating the loading component 2, and the clamping component 5 can be fixed during transportation to ensure the stability of transportation. The electric push rod 4 drives the detection component 7 to move toward the capacitor 6 transported on the loading component 2, so that the data is transmitted to the pressure sensor 8 through the detection component 7 to detect whether the strength of the capacitor 6 pin solder joints is qualified. When the detection work is completed, the loading component 2 will then proceed to the next round of transportation, thereby achieving the goal of automatic loading of the device, and no longer requiring manual inspection of the capacitors 6 one by one, thereby improving the qualified rate of the finished product.

[0032] The present invention can transport the capacitors 6 on the storage assembly 3 one by one through the rotation of the loading assembly 2, and the clamping assembly 5 can ensure the stability of the capacitor 6 during transportation, so that the electric push rod 4 drives the detection assembly 7 to detect the capacitor 6, and uses the pressure sensor 8 to detect whether the strength of the solder joints of the capacitor 6 pins is qualified, thereby achieving the goal of the device automatically loading and installing, and being able to detect each capacitor 6, ensuring the qualified rate of the finished products, and no longer requiring manual detection, saving time and labor, and the detection results are accurate, thereby improving work efficiency.

[0033] In one embodiment, for the above-mentioned loading component 2, the loading component 2 includes a motor 9, the motor 9 is installed on the upper surface of the L-shaped base 1, the motor 9 is equipped with a drive shaft 10 on the axis, the upper end of the drive shaft 10 is equipped with a disc 11 on the axis, the disc 11 is symmetrically provided with slots 12, the lower end of the slots 12 is equipped with an installation bin 13, and the number of the clamping components 5 is the same as that of the installation bin 13.

[0034] The driving motor 9 can drive the disc 11 to rotate through the driving shaft 10, so that the slot 12 corresponds to the storage component 3, so that the capacitor 6 can enter the installation chamber 13, and the installation chamber 13 can only enter one capacitor 6 at a time. Then, through the rotation of the disc 11, its slot 12 is moved to correspond to the detection component 7, so that the detection component 7 detects the strength of its capacitor 6, thereby achieving the ability to automatically transport the capacitors 6 one by one for detection operations, and can quickly detect each capacitor 6, ensuring accurate detection results, saving time and effort, and improving its work efficiency.

[0035] In one embodiment, for the above-mentioned storage component 3, the storage component 3 includes a storage box 14, the capacitors 6 are all installed in the storage box 14, the opening position of the storage box 14 is in contact with one side of the disc 11, a feeding spring 15 is installed at one end of the storage box 14, and a feeding plate 16 is installed on one side of the feeding spring 15, and the feeding plate 16 can slide in the storage box 14 through the feeding spring 15.

[0036] By installing the capacitor 6 in the storage box 14, the feeding spring 15 will be compressed in advance, so that when the slot 12 corresponds to the opening position of the storage box 14, the feeding plate 16 will slide in the storage box 14 through the expansion and contraction of the feeding spring 15, thereby feeding the capacitor 6 closest to the opening position of the storage box 14 into the installation bin 13, and then transporting it to the corresponding detection component 7 through the rotation of the disc 11, thereby achieving the goal of the device being able to transport the capacitors 6 and the detection components 7 one by one.

[0037] In one embodiment, for the above-mentioned installation bin 13, installation grooves 17 are provided on both sides of the installation bin 13, and the clamping assembly 5 includes a fixing frame 18, and the fixing frame 18 is installed on both sides of the installation bin 13. A sliding rod 19 is slidably installed on the fixing frame 18, and a clamping block 20 is installed at one end of the sliding rod 19. The clamping block 20 can be extended into the installation groove 17, and a clamping spring 21 is installed around the sliding rod 19.

[0038] When the capacitor 6 enters the mounting chamber 13, the sliding rod 19 will drive its clamping block 20 to disengage from the mounting groove 17 under the contraction of the clamping spring 21, so that the capacitor 6 can enter the mounting chamber 13. When the capacitor 6 completely enters the mounting chamber 13, the clamping block 20 will re-enter its mounting groove 17 through the clamping spring 21 to fix the capacitor 6 in its mounting chamber 13, thereby preventing the capacitor 6 from disengaging from the mounting chamber 13 when it is transported, thereby ensuring its stability.

[0039] In one embodiment, for the above-mentioned detection component 7, the detection component 7 includes a shell 22, and the shell 22 is installed on the telescopic rod part of the electric push rod 4. Sliding grooves 23 are provided at both ends of one side of the shell 22, and positioning grooves 24 are provided at both ends of the top of the shell 22. The clamping component 5 also includes a detection plate 25, and there are two detection plates 25. One end of the detection plate 25 is installed in the shell 22. One detection plate 25 can slide with the sliding groove 23 and the positioning groove 24 at one end, and one end of the detection plate 25 is an inclined surface.

[0040] When the disc 11 drives the capacitor 6 to rotate corresponding to its detection component 7, it can drive its electric push rod 4 to drive its detection component 7 to approach the capacitor 6, so that after the inclined surface of its detection plate 25 contacts the pin solder joint of its capacitor 6, it will slide on both sides in its positioning groove 24 and sliding groove 23, and then transmit its data to the pressure sensor 8 to detect whether the strength of its pin solder joint is qualified and whether it is firmly fixed.

[0041] In one embodiment, for the above-mentioned pressure sensor 8, the pressure sensor 8 is respectively installed at one end of the shell 22, and detection springs 26 are installed at both ends of the shell 22, one end of the spring is in contact with the detection plate 25, and the other end of the spring is in contact with the pressure sensor 8.

[0042] By bringing one end of the detection spring 26 into contact with the pressure sensor 8, when the detection plate 25 contacts the pin solder joint of its capacitor 6, the detection plate 25 will slide on both sides in its positioning groove 24 and sliding groove 23, thereby driving its detection spring 26 to deform, so that the detection spring 26 transmits its compressed pressure to the pressure sensor 8, thereby detecting whether the strength that the pin solder joint of its capacitor 6 can withstand is qualified, thereby achieving the goal that the device can perform detection operations independently, does not require much manual operation, and can ensure that its detection data is accurate and the detection operation is completed efficiently.

[0043] In summary, with the help of the above technical solution of the present invention, by installing the capacitor 6 in the storage box 14, the feeding spring 15 will be compressed in advance, and then the motor 9 will be driven to drive the disc 11 to rotate through the driving shaft 10, so that the slot 12 and the storage bin are aligned. The feeding plate 16 will slide in its storage box 14 through the extension and contraction of the feeding spring 15, thereby feeding the capacitor 6 closest to the opening position of the storage box 14 into the installation bin 13, and the installation bin 13 can only enter one capacitor 6 at a time, and when the capacitor 6 enters the installation bin 13, the sliding rod 19 will drive its clamping block 20 to disengage from the installation slot 17 under the contraction of the clamping spring 21, so that the capacitor 6 can enter the installation bin 13, and when the capacitor 6 completely enters the installation bin 13, the clamping block 20 will re-enter its installation slot 17 through the clamping spring 21 to fix the capacitor 6 in its installation bin 13, thereby preventing the capacitor 6 from disengaging from the installation bin 13 when it is transported, and then By rotating the disc 11, its slot 12 is moved to correspond to the detection component 7, so that the capacitors 6 can be automatically transported one by one for detection operation, and each capacitor 6 can be quickly detected, ensuring the accuracy of the detection structure, saving time and effort, and improving its work efficiency. When the disc 11 drives the capacitor 6 to rotate to correspond to its detection component 7, it can drive its electric push rod 4 to drive its detection component 7 to approach the capacitor 6. Because one end of its detection spring 26 contacts the pressure sensor 8, after the inclined surface of its detection plate 25 contacts the pin welding point of its capacitor 6, it will slide on both sides in its positioning groove 24 and sliding groove 23, causing its detection spring 26 to deform, so that the detection spring 26 transmits its compressed pressure to the pressure sensor 8, thereby detecting whether the strength that the pin welding point of its capacitor 6 can withstand is qualified, thereby achieving the goal of the device being able to perform detection operations independently, without the need for manual operation, and ensuring that its detection data is accurate and the detection operation is completed efficiently.

[0044] Through the above technical solution, 1.

By One end of 6 contacts with the pressure sensor 8, so that when the electric push rod 4 drives its detection component 7 to approach the capacitor 6, the inclined surface of the detection plate 25 will first contact the pin welding point of its capacitor 6, thereby driving its detection plate 25 to slide on both sides in its positioning groove 24 and sliding groove 23, so that its detection spring 26 is deformed, and the detection spring 26 transmits its compressed pressure to the pressure sensor 8, thereby detecting whether the strength that the pin welding point of its capacitor 6 can withstand is qualified, thereby achieving the goal that the device can perform detection operations independently, does not require much manual operation, and can ensure that its detection data is accurate and the detection operation is completed efficiently.
