Description

Technical Field

[0001] The utility model relates to the technical field of capacitor production equipment, in particular to a capacitor conveying buffer device. Background Art

[0002] The capacitor includes a chip and pins soldered on the chip.

[0003] In the production of capacitors, the capacitors are generally processed by inserting the pins into the braid for conveying. Usually, after the pins of the capacitor chip are welded, the welding effect needs to be inspected. After the welding inspection, the next step of coating process is required to apply epoxy resin.

[0004] In order to speed up production efficiency, capacitors are currently produced continuously on the production line. After completing the welding inspection process, the capacitors plugged into the tape are directly transported to the coating process for processing.

[0005] However, the distance between the welding inspection process and the painting process equipment on the production line is fixed, but the capacitors in the welding inspection process need to pause during inspection, while the painting process does not need to pause during painting, which can easily cause the tape between the welding inspection process and the painting process equipment to loosen and affect the transfer of the tape. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a capacitor conveying buffer device, which can tighten the braid between the welding inspection process and the coating process equipment to ensure that the transfer of the braid is not affected.

[0007] According to the first aspect of the utility model, a capacitor conveying buffer device comprises: a frame, on which a first material wheel and a second material wheel are rotatably arranged; a counterweight frame, which is slidably arranged on the frame up and down, is located below the first material wheel and the second material wheel, and is rotatably arranged with a tensioning wheel, the first material wheel, the tensioning wheel and the second material wheel support the movement of the tape in turn, and the first material wheel, the tensioning wheel and the second material wheel cooperate to tension the tape; a first elastic scraper, which is arranged on the frame and is used to scrape the capacitor chip passing through the second material wheel.

[0008] A capacitor conveying buffer device according to an embodiment of the utility model has at least the following beneficial effects:

[0009] 1.

It can be understood that the belt passes through the first material wheel, the tensioning wheel and the second material wheel in turn, and the counterweight frame can drive the tensioning wheel to pull the tensioned belt downward, so that the counterweight frame can adjust its height according to the length of the belt between the first material wheel and the second material wheel, thereby ensuring that the belt between the first material wheel and the second material wheel is tensioned, and then, the belt between the welding inspection process and the coating process equipment is tensioned, to ensure that the transfer of the belt is not affected by the difference in conveying speed of the belt by the welding inspection process and the coating process equipment.

[0031] A capacitor conveying buffer device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A capacitor conveying buffer device according to an embodiment of the utility model includes a frame 100 and a counterweight frame 130 .

[0033] Regarding the frame 100 , a first material wheel 110 and a second material wheel 120 are rotatably disposed on the frame 100 .

[0034] The counterweight frame 130 is slidably arranged on the frame 100 up and down, and is located below the first material wheel 110 and the second material wheel 120. The counterweight frame 130 is rotatably provided with a tensioning wheel 140, and the first material wheel 110, the tensioning wheel 140 and the second material wheel 120 support the movement of the braid in turn, and the first material wheel 110, the tensioning wheel 140 and the second material wheel 120 cooperate to tension the braid.

[0035] It can be understood that the braid passes through the first material wheel 110, the tensioning wheel 140 and the second material wheel 120 in sequence, and the counterweight frame 130 can drive the tensioning wheel 140 to pull the tensioned braid downward, so that the counterweight frame 130 can adjust its height according to the length of the braid between the first material wheel 110 and the second material wheel 120, thereby ensuring that the braid between the first material wheel 110 and the second material wheel 120 is tensioned, and then, the braid between the welding inspection process and the painting process equipment is tensioned, ensuring that the transfer of the braid is not affected by the difference in the conveying speed of the braid between the welding inspection process and the painting process equipment.

[0036] In some specific embodiments, two vertical rods 270 are provided on the frame 100, and two guide holes for accommodating the sliding of the vertical rods 270 are provided on the counterweight frame 130.

At least one third material wheel 160 is provided, and the number of tensioning wheels 140 is one more than the number of third material wheels 160. The tape between the first material wheel 110 and the second material wheel 120 passes alternately on the tensioning wheel 140 and the third material wheel 160, thereby extending the length of the tape between the first material wheel 110 and the second material wheel 120.

When the adhesion between the chip and the pin is sufficient, when the first elastic scraper 150 scrapes the chip, the chip can squeeze and deform the first elastic scraper 150 to accommodate the capacitor to pass through, and the welding of the chip and the pin after passing through the first elastic scraper 150 will not fall off, thereby facilitating the removal of capacitors with poor adhesion between the chip and the pin, thereby realizing the function of the conveying buffer device to remove products with poor welding or false welding.

[0042] In some specific embodiments, a second elastic scraper 180 is further provided on the frame 100, and the second elastic scraper 180 is used to scrape the chip of the capacitor passing through the discharge wheel 170.

[0043] In some specific embodiments, a third elastic scraper 190 is also provided on the frame 100. The third elastic scraper 190 is located at the discharge end of the discharge wheel 170. The third elastic scraper 190 has two elastic scraper heads 200. The two elastic scraper heads 200 are respectively used to scrape the two sides of the chip, so that the third elastic scraper 190 can scrape both sides of the chip at the same time to detect the adhesion between the chip and the pin, thereby further optimizing the function of the conveying buffer device to eliminate poor welding or false welding of products.

[0044] In some specific embodiments, a dust brush assembly 210 is provided on the frame 100, and the dust brush assembly 210 is located between the second material wheel 120 and the discharge wheel 170. The dust brush assembly 210 is used to brush off the dust on the braid and the capacitor, thereby preventing the dust on the capacitor from being carried by the capacitor to the next coating process of epoxy resin and affecting the coating effect.

[0045] Specifically, the dust brush assembly 210 includes two mounting plates 220 and two groups of brushes 230 respectively arranged on the two mounting plates 220.
