DETAILED DESCRIPTION
[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0024] like Figure 1-3As shown, a handheld pole group pole ear edge spacing test tool includes a pole group positioning plate 1 for positioning the pole group, and two standard line grooves 2 are provided on the pole group positioning plate, and the two inner side walls of the standard line groove are defined as standard line size identification lines 21. Further, a transparent stopper 3 for detecting the position of the pole ear is installed in the standard line groove, and the two inner arms of the transparent stopper are defined as control line size identification lines 31. If the pole ear is between the two control line size identification lines 31, the pole group is a qualified product and can be circulated normally. If the pole ear is between the control line size identification line 31 and the standard line size identification line 21, although the pole group is also a qualified product, it is necessary to debug the equipment so that the pole ear is between the two control line size identification lines 31. By comparing the positions of the standard line size identification line 21 and the control line size identification line 31 with the pole ear of the pole group, the pole group is detected. The pole group does not need to be taken out when it is located in the unloading tray, and the pole group does not need to be moved. The pole group on the unloading tray can be fully detected, and qualified products are circulated normally, and defective products are picked out, and the operation is convenient.
[0025] like Figure 2 As shown, specifically, the pole group positioning plate is composed of an upper bottom plate 11, a left positioning plate 12, a right positioning plate 13 and a front positioning plate 14. The standard wire slot is arranged on the upper bottom plate. The left positioning plate and the right positioning plate are respectively fixed on both sides of the bottom of the upper bottom plate. The left positioning plate and the right positioning plate have the same structure. The left and right positioning plates are respectively provided with positioning grooves 15 for clamping both sides of the pole group. Figure 2 As shown, the positioning groove is formed by the left and right positioning plates and the upper base plate, and can position the two angles of the front end of the pole group. In order to limit the front end of the pole group, the front positioning plate is fixed to the lower part of the upper base plate, and the front positioning plate blocks the front end of the pole group. In this embodiment, there are two front positioning plates.
[0026] In order to facilitate workers to operate the pole group positioning plate, a tool handle 4 is fixed on the upper part of the upper base plate. The tool handle is fixed in the center of the upper part of the upper base plate.
[0027] like Figure 4 As shown, the transparent stopper is U-shaped, fixed in the middle by bolts in the standard wire trough, and the two sides of the transparent stopper are tightly fitted with the inner wall of the standard wire trough. The width of the two sides of the transparent stopper is set according to the condition of the pole ear.
[0028] In order to prevent the tool from scratching the side of the pole group when pressing the pole group from top to bottom, the lower parts of the left positioning plate, the right positioning plate and the front positioning plate are chamfered respectively. The chamfered structure allows the tool to be smoothly buckled on the top of the pole group without damaging the surface of the pole group.
[0029] When in use, the pole group is placed in the pole group turnover tray, and the tooling handle is held to bring the tooling above the pole group, and gently pressed down so that the tooling contacts the pole group, so that the positioning structures on both sides of the tooling contact the side edges of the pole group, and the pole group is positioned. The position of the pole ear is observed through the two limit blocks of the tooling, and the boundary position of the pole ear is compared with the transparent limit block and the standard line slot position to determine whether the pole group is qualified. Specifically, the pole group 5 is placed in the test tooling, and the line of sight is perpendicular to the tooling to observe the position of the pole ear 6 of the pole group. If the position of the pole ear is within the standard line size identification line 21 and exceeds the control line identification line 31, the pole group is qualified and can be released for circulation, but the equipment (winding machine) needs to be debugged so that the position of the pole ear is within the range of the control line identification line 31. The pole group is qualified and can be circulated normally. If the position of the pole ear is outside the standard line size identification line 21, the pole group is unqualified and cannot be circulated normally.
[0030] The utility model provides a handheld pole group and pole ear edge spacing test tool. The design of the tool can simply and intuitively measure the pole group. After the pole group is unloaded onto a transfer tray, the operator uses the tool to measure the edge spacing of the pole group. During the measurement process, the pole group does not need to be taken out of the tray again and can be directly tested. The transparent limit block is made of transparent material, and the human eye can directly and clearly determine whether the pole group is qualified. The tool is light and can be handheld for testing, which is convenient for personnel to operate. The tool itself has standard lines and control lines marked, which can intuitively distinguish between qualified and unqualified pole groups.
[0031] It should be pointed out that the device can be used to transport semi-finished lithium batteries, provide vacuum or inert gas according to requirements, and select different accessories for combination to make full use of space and improve work efficiency. For ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the scope of protection of the utility model.
