Definitions

  • the present invention pertains to a cleaning jig, more specifically to the cleaning jig for cleaning a test device
  • test devices For electronic equipment that requires high precision, such as test devices, it is necessary to perform maintenance or cleaning correctly for reducing errors in measurements.
  • the test device needs to clamp electrodes of a battery with test portions in the first place, and then charge and discharge the battery through the test portions to check whether the battery is working normally.
  • the test portions since the electrodes of the battery are often covered with an oxide film when the battery is manufactured, the test portions also need to scrap off the oxide film while clamping the electrodes. As a result, the surface of each test portion may be stained with scraped oxide film or some residues after a period of use.
  • the oxide film on the surface of each test portion may not only affect the efficiency of charging and discharging the battery, but also may interfere with the accuracy of the detection.
  • the test portion needs to transmit large current, scraped oxide film or residues on the surface of each test portion may also cause smoke or fire accidents.
  • it is very important to clean the test portions of the test device regularly, but it is also very troublesome to clean the test portions of the test device.
  • one test device generally needs to test a large number of batteries in batches. Assuming that one electrode of each battery corresponds to one test portion, it can be imagined that the test device will have a large number of test portions. Cleaning the test portions of the test device one by one must be very time-consuming and laborious. Accordingly, the industry needs a new cleaning jig that can quickly clean multiple test portions of the test device in batches, so as to reduce the downtime of the test device due to cleaning, and also reduce the manpower and resources for cleaning the test device.
  • the present invention provides a cleaning jig, which can quickly and massively clean multiple test portions of a test device without stopping the test device, thereby improving the detection efficiency of the test device.
  • the present invention discloses a cleaning jig for cleaning a plurality of test portions in a test device.
  • the cleaning jig comprises a frame and a plurality of cleaning units.
  • the frame has a first side which located at an outer edge of the frame.
  • the plurality of cleaning units are detachably disposed on a first side of the frame.
  • Each of the cleaning units has a cleaning sheet, and the cleaning sheet of each of the cleaning units extends outwardly of the frame.
  • Each of the cleaning units corresponds to one of the test portions, and each of the test portions contacts a first surface and a second surface of the corresponding cleaning sheet at the same time.
  • each of the cleaning units may have a first locking member, and the first locking member detachably fixes the first side.
  • each of the cleaning units may have a second locking member, and the second locking member detachably fixes the cleaning sheet.
  • the locking direction of the first locking member may be different from the locking direction of the second locking member.
  • the first side and the second side of the cleaning sheet may be made of sandpaper.
  • test portions of the test device are used to test a plurality of electronic components on a carrier
  • the frame is defined with a frame length and a frame width
  • the frame length may be equal to the length of the carrier
  • the frame width may be equal to the width of the carrier.
  • setting positions of the cleaning units on the first side may correspond to placement positions of the electronic components on the carrier.
  • the cleaning jig provided by the present invention can be used to clean the test device, and the test portions of the test device can clamp the cleaning sheet and grind away residues by itself without manually cleaning the test portions one by one.
  • the cleaning jig provided by the present invention can quickly clean multiple test portions of the test device in batches, so as to reduce the downtime of the test device due to cleaning, and also reduce the manpower and resources for cleaning the test device.
  • FIG. 1 is a perspective view of a cleaning jig in accordance with an embodiment of the present invention.
  • FIG. 2 is a perspective view of a cleaning unit in accordance with an embodiment of the present invention.
  • the cleaning jig 1 includes a frame 10 and a plurality of cleaning units 12.
  • the plurality of cleaning units 12 can be arranged on two sides of the frame 10, and a cleaning sheet 126 in each cleaning unit faces or extend toward the outside of the frame 10.
  • the two sides of the frame 10 can be defined as a first side 100 and a second side 102, respectively, and the plurality of cleaning units 12 can be divided into two groups.
  • One group of the cleaning units 12 is disposed on the first side 100, and another group of the cleaning units 12 are disposed on the second side 102. As shown in FIG. 1 , the plurality of cleaning units 12, disposed on the first side 100, are arranged in a row, and the cleaning sheets 126 in each cleaning units 12 are generally oriented at the same angle, for example, vertically toward the outside of the frame 10.
  • the function of the cleaning jig 1 is to clean the test device, especially to clean the test portion of the test device (not shown in FIG. 1 ).
  • the test portion of the test device can be used to test electronic components (not shown).
  • the electronic component may be a battery
  • the test device is a device used to detect whether the battery is working normally.
  • the test portions need to be firmly electrically connected to the electrodes in the first place, then the charge and discharge tests can be performed.
  • each of the test portion must clamp one electrode to prevent accidentally falling off.
  • this embodiment does not limit the electronic component to be a soft-pack battery, nor does it limit the electrode to be sheet-shaped. As long as the test portion of the test device is electrically connected to the electrode of the electronic component by clamping the electrode, it should be within the scope of this embodiment.
  • multiple electronic components can be placed on a carrier (not shown), and then the entire carrier is placed in a storage location of the test device, so that multiple electronic components can be tested together.
  • the test device will have multiple test portions, so that each test portion can be electrically connected to the electrode of one of the electronic components.
  • This embodiment does not limit the position of the electrode of the electronic component.
  • a plurality of electronic components can be disposed on two sides of the carrier, and the electrode of each electronic component can be perpendicular to the outside of the carrier.
  • the arrangement of multiple electronic components in the carrier can be similar to the cleaning jig 1 shown in FIG. 1 of this embodiment.
  • the carrier can be compared to the frame 10 of the cleaning jig 1, and the electronic components can be compared to the cleaning units 12 of the cleaning jig 1, and the electrode of the electronic component can be compared to the cleaning sheet 126 of the cleaning unit 12.
  • the cleaning jig 1 does not have real electronic components (such as the battery to be tested), the cleaning jig 1 can still simulate the appearance of the carrier having multiple electronic components.
  • the frame 10 can be defined with a frame length L and a frame width W, and the frame length L and the frame width W are both smaller than the length and width of the carrier.
  • the frame length L may also be exactly equal to the length of the carrier
  • the frame width W may also be exactly equal to the width of the carrier.
  • the height of the frame 10 can also be defined as a frame height H, and the frame height H should be smaller than the height of the carrier.
  • the frame height H can also be exactly equal to the height of the carrier, so that when the frame length L, the frame width W, and the frame height H equal to and the length, width, and height of the carrier, the volume and the appearance of the frame 10 should be roughly the same as the carrier.
  • FIG. 2 is a perspective view of a cleaning unit in accordance with an embodiment of the present invention
  • FIG. 3 is a side view of the cleaning unit in accordance with an embodiment of the present invention.
  • FIG. 2 shows the cleaning unit 12 of the cleaning jig 1.
  • the cleaning unit 12 has a body 120 on which a first locking member 122, a second locking member 124, and a cleaning sheet 126 are disposed.
  • the first locking member 122 can be used to lock the frame 10 of the cleaning jig 1, for example, to lock the first side 100 of the frame 10.
  • the frame 10 and the cleaning unit 12 will not move or rotate relatively, so that the cleaning sheet 126 can be kept stable.
  • the cleaning unit 12 can be detached from the frame 10, thereby the cleaning unit 12 can be maintained or replaced.
  • the body 120 is composed of two similar plate-like structures, which are defined as a first clamping plate 120a and a second clamping plate 120b, and a second locking member 124 can be used to lock the first clamping plate 120a and the second clamping plate 120b.
  • the locking directions of the first locking member 122 and the second locking member 124 are different, for example, the locking directions of the first locking member 122 and the second locking member 124 may be perpendicular to each other.
  • one end of the cleaning sheet 126 can be sandwiched between the first clamping plate 120a and the second clamping plate 120b, and the other end of the cleaning sheet 126 is exposed to clean the test portion 2.
  • the cleaning sheet 126 is a double-sided sheet-like element, and both sides (a first side and a second side) of the cleaning sheet 126 may have sandpaper-like rough surfaces.
  • the cleaning sheet 126 may also be a piece of sandpaper folded in half, and the smooth side of the sandpaper is folded inwardly that the rough side of the sandpaper is exposed.
  • the first surface and the second surface of the cleaning sheet 126 may both be the same rough side of the sandpaper. It is worth mentioning that this embodiment does not limit how many test portions 2 can clamp one cleaning sheet 126 at the same time.
  • FIG. 3 shows that two test portions 2 might clamp one cleaning sheet 126 at the same time, it is also possible that there is only one test portion 2 might clamp the cleaning sheet 126.
  • the test portions 2 when the test device tests the electronic component, the test portions 2 not only clamp the electrodes of the electronic component, but also have to rub or friction the electrodes to scrape off the oxide film on the surface of the electrodes. After a period of time, it is inevitable that residues of the oxide film or some dust will adhere to the test portions 2, so the test portions 2 must be cleaned regularly.
  • the electronic components on the carrier can be pulled out from a storage location, and put the cleaning jig 1, as the replacement, into the storage location.
  • the engineer can issue the same instruction to the test device, for example, the instruction of controlling the test portion 2 of the test device to clamp the electrode of the electronic component.
  • this embodiment does not limit the instructions received by the test device, an engineer may also issue instructions designed for the self-cleaning process of the test device.
  • the test portion 2 of the test device will clamp the cleaning sheet 126 at the position where the electrode of the electronic component was originally expected to be clamped.
  • the test portion 2 has to rub or friction the cleaning sheet 126, the residue and dust accumulated on the test portion 2 can be rubbed off by the rough surface of the cleaning sheet 126, so as to achieve the purpose of cleaning the test portion 2.
  • the engineer can give the same instructions more than once to the test device that the test portion 2 can clamp the cleaning sheet 126 several times to improve the cleaning process. It can be seen from the above that the test device can clean itself with the cleaning jig 1, instead of making the cleaning sheet 126 to rub or friction the test portion 2 actively. Therefore, the cleaning process can be completed by giving the existing instructions such as instructions for clamping the electrode.
  • the second locking member 124 can also be released to slightly separate the first clamping plate 120a from the second clamping plate 120b.
  • the engineer can withdraw the used cleaning sheet 126 from between the first clamping plate 120a and the second clamping plate 120b and replace it with a new one.
  • this embodiment has obvious advantages, that is, a cleaning jig 1 can be used to clean a larger number of test portions 2 at one time.
  • this embodiment only needs to replace the cleaning sheets 126 to clean the test portions 2 in the next storage location, and the test device does not need to be shut down for cleaning the test portions 2, which also means that the efficiency of the test device can be greatly improved.
  • the cleaning jig provided by the present invention can be used to clean the test device, and the test portions of the test device can clamp the cleaning sheet and grind away residues by itself without manually cleaning the test portions one by one.
  • the cleaning jig provided by the present invention can quickly clean multiple test portions of the test device in batches, so as to reduce the downtime of the test device due to cleaning, and also reduce the manpower and resources for cleaning the test device.
