Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for connecting the shafts of a loading trolley, and in particular to an auxiliary positioning device for connecting the loading shafts of a loading trolley and a loading trolley containing the same. Background Technology

[0002] Laser die-cutting is an essential process in the production of lithium batteries. Currently, the loading operation of laser die-cutting equipment is usually done manually. The operator operates the loading trolley to transport the positive / negative electrode rolls prepared in the rolling process to the loading end of the die-cutting equipment. Then, the loading shaft of the loading trolley is aligned with the unwinding shaft of the equipment, and the rolls are pushed onto the unwinding shaft to complete the loading operation.

[0003] During the docking process between the feeding shaft and the unwinding shaft, the operator cannot see the relative positions of the two shafts from the feeding trolley operating position due to the obstruction of the material roll. Therefore, another operator needs to stand at the unwinding shaft end of the equipment to assist in determining the relative positions of the two shafts. If there is only one operator, he / she needs to go to the unwinding shaft end to check the relative positions of the two shafts, and then return to the feeding trolley operating position to adjust the position and height of the feeding shaft. This process needs to be repeated many times before the two shafts can be successfully docked coaxially to complete the feeding. This process usually takes tens of seconds to several minutes, wasting time and manpower. Utility Model Content

[0006] The first aspect is to provide an auxiliary positioning device for docking the loading shaft of a loading trolley, including a loading shaft docking auxiliary positioning mechanism disposed on the loading trolley, and a positioning plate disposed on an external device for cooperating with the loading shaft docking auxiliary positioning mechanism; the loading shaft docking auxiliary positioning mechanism includes:

[0007] A lockable slider guide rail mechanism, the lockable slider guide rail mechanism including a guide rail and a lockable slider disposed on the guide rail;

[0008] A fixed base is provided, the top end of which is fixedly connected to the bottom end of the guide rail, and the bottom end of which is detachably connected to the loading trolley, so that the guide rail is perpendicular to the horizontal plane.

[0009] A positioning device is vertically mounted on the lockable slider to achieve precise docking between the loading trolley and the external device.

[0010] Furthermore, the positioning device is a positioning laser pointer, which is vertically fixed on the lockable slider, such that the line of the laser emitted by the laser is parallel to the axis of the loading shaft of the loading trolley, and the laser emitted by the laser is directed toward the positioning plate on the external device.

[0011] Furthermore, the length of the guide rail is greater than the radius of the largest roll in actual production.

[0012] Furthermore, the length and width of the vertical cross-section of the lockable slider are both greater than the cross-sectional diameter of the positioning laser pen base.

[0013] Furthermore, the bottom end of the fixed seat is an I-shaped clamp, which is inserted into the top of the lifting plate of the loading shaft of the loading trolley through an interference fit.

[0014] Furthermore, one side of the positioning plate is an adhesive surface for attaching to the mounting plate of the external device, and the mounting plate is vertically fixed with an unwinding shaft; the center of the other side has a non-penetrating frustum-shaped blind hole for receiving the laser emitted by the positioning laser pen.

[0015] Furthermore, the diameter of the blind hole at the end near the adhesive surface is less than or equal to 50% of the diameter at the other end of the blind hole.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0027] refer to Figure 1-3 A preferred embodiment of an auxiliary positioning device for docking the loading shaft of a loading trolley is provided, comprising a loading shaft docking auxiliary positioning mechanism 1 disposed on the loading trolley, and a positioning plate 7 disposed on an external device for cooperating with the loading shaft docking auxiliary positioning mechanism 1; the loading shaft docking auxiliary positioning mechanism 1 includes:

[0028] Lockable slider guide rail mechanism 2, the lockable slider guide rail mechanism 2 includes guide rail 3, and lockable slider 4 disposed on guide rail 3;

[0029] The top of the fixed seat 6 is fixedly connected to the bottom of the guide rail 3, and the bottom of the fixed seat 6 is detachably connected to the loading trolley, so that the guide rail 3 is perpendicular to the horizontal plane.

[0030] The positioning device is a positioning laser pointer 5, which is vertically fixed on the lockable slider 4, so that the line of the laser emitted by it is parallel to the axis of the loading shaft 11 of the loading trolley, and the laser emitted by it is directed toward the positioning plate 7 on the external device.

[0031] This embodiment also provides a loading trolley, including the above-mentioned auxiliary positioning device. The loading trolley also includes a loading trolley body 9, and the loading trolley body 9 includes a loading lifting plate 10. A loading shaft 11 is vertically fixedly connected to the upper part of the loading lifting plate 10.

[0032] The feeding shaft docking auxiliary positioning mechanism 1 is installed vertically and horizontally on the feeding lifting plate 10 of the feeding trolley, so that the line of the laser emitted by the positioning laser pen 5 is parallel to the axis of the feeding shaft 11, and the laser emitted by the positioning laser pen 5 is directed towards the positioning plate 7 on the external device; preferably, the external device is a die-cutting device.

[0033] By projecting light spots onto the positioning plate at a predetermined position through the auxiliary positioning mechanism of the feeding shaft docking, the operator can quickly align the feeding shaft of the feeding trolley with the unwinding shaft of the die-cutting equipment, so that the two shafts can be quickly and coaxially docked to complete the feeding. This avoids the need for multiple people to work together or for a single person to move and check the relative position of the feeding shaft and the unwinding shaft multiple times, saving manpower and time and significantly improving production efficiency.

[0034] In a preferred embodiment, the length of the guide rail 3 is greater than the radius of the largest roll in actual production to prevent the roll 12 from blocking the projection point of the positioning laser pointer 5. When the roll 12 blocks the projection point of the positioning laser pointer 5, the lockable slider 4 can be adjusted upward along the guide rail 3 by a certain distance until it exceeds the blocking height of the roll 12, and then locked and fixed so that the positioning laser pointer 5 can project the light point onto the positioning plate 7.

[0035] In a preferred embodiment, the length and width of the vertical cross-section of the lockable slider 4 are both greater than the cross-sectional diameter of the base of the positioning laser pointer 5, so that the positioning laser pointer 5 can be fixed on the lockable slider 4. More preferably, the center of the base of the positioning laser pointer 5 is concentric with the center of the vertical cross-section of the lockable slider 4.

[0036] In a preferred embodiment, the bottom end of the fixed seat 6 is an I-shaped clamp, which is inserted into the top end of the loading shaft lifting plate 10 of the loading trolley through an interference fit.

[0037] In a preferred embodiment, one side of the positioning plate 7 is an adhesive surface, used to adhere the positioning plate 7 to the mounting plate 14 of the die-cutting equipment. The mounting plate 14 is vertically fixed with a roll unwinding shaft 13. The other side has a non-penetrating, frustum-shaped blind hole 8 at its center, used to receive the laser emitted by the positioning laser pointer 5. The diameter of the blind hole 8 near the adhesive surface is less than or equal to 50% of the diameter of the other end of the blind hole 8, making the projection position of the laser pointer 5 more precise, thus enabling more accurate and rapid loading and unloading. It should be noted that, with the cooperation of the lockable slider 4, the positioning plate 7 can be adhered to the die-cutting equipment at any suitable height within the stroke of the lockable slider guide mechanism 2, thereby avoiding interference with other components of the equipment.

[0038] The auxiliary positioning device for docking the loading shaft of the loading trolley described above has the following working principle:

[0039] When the operator first aligns the loading trolley with the loading shaft 11 and the unwinding shaft 13, other operators or a single person must assist in checking the relative positions of the loading shaft 11 and the unwinding shaft 13 and continuously adjust the height of the loading shaft 11 until the two shafts are coaxially aligned. The material roll 12 is then pushed onto the unwinding shaft 13 via the loading shaft 11, completing the loading process. At this point, the height of the lockable slider 4 on the loading shaft alignment auxiliary positioning mechanism 1 is adjusted so that the positioning laser pointer 5 projects a light spot onto the appropriate position on the mounting plate 14 of the opposite die-cutting equipment. This ensures that the projected light spot does not interfere with other components of the die-cutting equipment. Then, the positioning plate 7 is attached to this position, aligning the projected light spot with the blind hole 8 on the positioning plate 7. This completes the mutual positioning of the loading shaft alignment auxiliary positioning mechanism 1 and the positioning plate 7, thereby achieving coaxial positioning of the loading shaft 11 and the unwinding shaft 13 of the loading trolley.

[0040] After the mutual positioning of the loading shaft docking auxiliary positioning mechanism 1 and the positioning plate 7 is completed, that is, the coaxial positioning of the loading shaft 11 and the unwinding shaft 13 of the loading trolley is achieved, each time the operator operates the loading trolley to dock the loading shaft 11 and the unwinding shaft 13, he only needs to determine the lateral position of the loading trolley and adjust the height of the loading shaft 11 so that the light spot projected by the positioning laser pen 5 coincides with the blind hole 8 on the positioning plate 7. This will determine that the loading shaft 11 and the unwinding shaft 13 are coaxial. Then the material roll 12 is pushed onto the unwinding shaft 13 through the loading shaft 11 to complete the loading.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the content and illustrations of the present utility model should be included within the protection scope of the present utility model.
