Description

Technical Field

[0001] This utility model relates to the field of battery processing and manufacturing technology, and in particular to an overflow adhesive cutting device. Background Technology

[0002] Plastic components are essential parts within batteries, used for sealing and insulation between metal components. When removing excess material from injection-molded plastic parts, problems such as stringing or damage can occur, leading to assembly difficulties, sealing failures, or insulation failures. Therefore, any excess plastic material detected in plastic parts must be completely removed to prevent defective products from being released. However, current technology requires manual removal of excess material, which often results in uneven cuts, incomplete removal, stringing, and low efficiency. Utility Model Content

[0013] Optionally, the second clamping plate has two first positioning protrusions on the end face of the cutting blade. The two first positioning protrusions are respectively located on both sides of the cutting blade along a third direction to restrict the movement of the cutting blade along the third direction. The third direction is perpendicular to both the first direction and the second direction.

[0014] Optionally, along a third direction, the length of the cutting blade is greater than the length of the positioning plate, the length of the cutting blade is less than the length of the first clamping plate, and the third direction is perpendicular to both the first direction and the second direction.

[0015] Optionally, the first clamping plate has two second positioning protrusions on the end face of the cutting blade.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] like Figures 1-3 As shown, the glue overflow cutting device in this embodiment includes a positioning plate 1 and a cutting blade 2. Wherein, as... Figure 3 As shown, direction ab is the first direction, direction cd is the second direction, and direction ef is the third direction. Optionally, the positioning plate 1 can be placed flat, that is, the first direction is vertical, and the second and third directions are both horizontal. Of course, in other embodiments, the positioning plate 1 can also be placed according to actual usage requirements, and does not necessarily have to be flat.

[0033] like Figure 2 As shown, the positioning plate 1 has a positioning recessed area 11 that sinks downward along a first direction. The positioning recessed area 11 has a first clearance notch 111 on one side along a second direction, and the workpiece 900 to be cut is located at the first clearance notch 111. A cutting blade 2 is disposed in the positioning recessed area 11, and the sharp part 21 of the cutting blade 2 protrudes from the first clearance notch 111 along the second direction, so that the sharp part 21 can cut the excess adhesive of the workpiece 900. The second direction is perpendicular to the first direction. By holding the workpiece 900 by hand or with a robotic arm, and moving or rotating it at the first clearance notch 111, the sharp part 21 can cut off the excess adhesive of the workpiece 900.

[0034] The positioning plate 1 helps to fix the relative position of the cutting blade 2 and the workpiece 900 to be cut, preventing excessive cutting depth that could damage the plastic parts or other components of the workpiece 900. It also helps to prevent insufficient cutting depth that could result in incomplete cutting or stringing. The positioning plate 1 also allows for quick and accurate positioning of the workpiece 900 and the sharp part 21. For workpieces 900 of the same model, only one accurate positioning of the appropriate size positioning plate 1 is needed to efficiently complete a batch of cutting work, ensuring cutting quality while improving cutting efficiency.

[0035] Optionally, the positioning plate 1 also includes a first connecting area 12. Since the wall thickness of the first connecting area 12 and the positioning sinking area 11 are different, the end faces of the two facing the cutting blade 2 are not at the same height. Therefore, the connection position of the first connecting area 12 and the positioning sinking area 11 has a limiting surface. When the cutting blade 2 is cutting, it will be subjected to force and will abut against the limiting surface. The limiting surface can prevent the cutting blade 2 from moving away from the workpiece 900 along the second direction.

[0036] Optionally, in this embodiment, the part to be cut 900 is a partial structure of a button battery, i.e., a cylindrical structure. Optionally, the part to be cut 900 includes a metal bottom cover 901 and a plastic ring 902. The plastic ring 902 protrudes circumferentially along the side wall of the cylindrical structure, and excess adhesive is generally located at the junction of the plastic ring 902 and the bottom cover 901, i.e., the excess adhesive is located at the side wall of the cylindrical structure. Correspondingly, the first clearance notch 111 has a curved side wall 112, which is provided through in a first direction. The side wall of the cylindrical structure can be attached to the curved side wall 112, i.e., when placing the part to be cut 900, the axial direction of the cylindrical structure needs to be in the first direction. The upper and lower end faces of the part to be cut 900 are held by hand or by a robotic arm, so that the part to be cut 900 rotates around its own axis at the first clearance notch 111. The sharp part 21 can then contact the side wall of the cylindrical structure, thereby cutting off the excess glue of the plastic ring 902.

[0037] To further prevent the cutting blade 2 from dislodging from the positioning sinking area 11 along the first direction, the glue overflow cutting device may optionally include a first clamping plate 3. The first clamping plate 3 is disposed on the side of the positioning plate 1 where the cutting blade 2 is placed, and the cutting blade 2 is clamped between the clamping area 31 of the first clamping plate 3 and the positioning sinking area 11.

[0038] Optionally, a second clearance notch 311 is provided on the side of the clamping area 31 near the workpiece 900 to be cut. The second clearance notch 311 is used to avoid the workpiece 900 to be cut and the sharp part 21. The second clearance notch 311 is located on the side of the clamping area 31 near the workpiece 900 to be cut, that is, the second clearance notch 311 is not through-type in the first direction, but is complete away from the end face of the cutting blade 2. This arrangement ensures that when the operator touches the outer end face of the first clamping plate 3, he will not be injured by the cutting blade 2.

[0039] Optionally, the first clamping plate 3 further includes a second connecting region 32, which is connected to the clamping region 31 and is used to connect with components such as the positioning plate 1.

[0040] Optionally, along the third direction, the length of the cutting blade 2 is greater than the length of the positioning plate 1, and the portion of the cutting blade 2 extending beyond the positioning plate 1 can be held by the operator for easy placement and removal of the cutting blade 2. Optionally, along the third direction, the length of the cutting blade 2 is less than the length of the first clamping plate 3, that is, the first clamping plate 3 completely covers the cutting blade 2 and the positioning plate 1, which can prevent the operator from being injured by the cutting blade 2.

[0041] To prevent the cutting blade 2 from moving relative to the positioning plate 1 and the first clamping plate 3 in a third direction, optionally, the first clamping plate 3 has two second positioning protrusions (not shown in the figure) protruding from the end face of the cutting blade 2. The two second positioning protrusions are located on both sides of the cutting blade 2 in a third direction to restrict the movement of the cutting blade 2 in that direction. It should be noted that the protrusion height of the second positioning protrusions cannot exceed the sinking depth of the positioning sinking area 11 to prevent the second positioning protrusions from abutting against the positioning sinking area 11, thus preventing the first clamping plate 3 and the positioning plate 1 from clamping the cutting blade 2 tightly.

[0042] Alternatively, the thickness of the cutting blade 2 may be greater than or equal to the sinking depth of the positioning sinking area 11, so as to further ensure that the first clamping plate 3 and the positioning plate 1 can clamp the cutting blade 2, and prevent the cutting blade 2 from moving through greater friction.

[0043] To ensure that the bottom surface of the positioning plate 1 and the bottom surface of the workpiece 900 to be cut are on the same plane, the overflow cutting device may optionally include a second clamping plate 4. Along the first direction, the positioning plate 1 is clamped between the first clamping plate 3 and the second clamping plate 4, and the workpiece 900 to be cut is located in the placement area 41 of the second clamping plate 4. That is, both the positioning plate 1 and the workpiece 900 to be cut are located on the second clamping plate 4. Therefore, to ensure that the cutting blade 2 corresponds precisely to the overflow position of the workpiece 900, when one end of the plastic ring 902 of the workpiece 900 contacts the second clamping plate 4, the wall thickness of the positioning recessed area 11 of the positioning plate 1 must be consistent with the height of the plastic ring 902 of the workpiece 900. When one end of the bottom cover 901 of the workpiece 900 contacts the second clamping plate 4, the wall thickness of the positioning recessed area 11 of the positioning plate 1 must be consistent with the distance from the end face of the bottom cover 901 to the overflow position along the axial direction of the plastic ring 902.

[0044] Optionally, the second clamping plate 4 further includes a third connecting area 42, which is connected to the placement area 41 and is used to connect with components such as the positioning plate 1 and the first clamping plate 3.

[0045] Optionally, the positioning plate 1, the first clamping plate 3, and the second clamping plate 4 are detachably connected, making it convenient to replace different positioning plates 1 according to the size of the workpiece 900 to be cut.

[0046] Optionally, the positioning plate 1, the first clamping plate 3, and the second clamping plate 4 are screwed together. The adhesive overflow cutting device also includes a bolt 5. The second clamping plate 4 has a threaded hole extending in a first direction, and both the first clamping plate 3 and the positioning plate 1 have through holes extending in the first direction. The bolt 5 passes through the through holes of the first clamping plate 3 and the positioning plate 1 and is screwed into the threaded hole. Specifically, the threaded hole of the second clamping plate 4 is located within the third connecting region 42 of the second clamping plate 4, the through hole of the first clamping plate 3 is located within the second connecting region 32 of the first clamping plate 3, and the through hole of the positioning plate 1 is located within the first connecting region 12 of the positioning plate 1.

[0047] Optionally, two sets of bolts 5, threaded holes, and through holes are provided to prevent relative rotation of the positioning plate 1, the first clamping plate 3, and the second clamping plate 4 if only one set is provided. Of course, in other embodiments, three, four, or more sets of bolts 5, threaded holes, and through holes may be provided, which is not limited here.

[0048] Optionally, to prevent the cutting blade 2 from moving along a third direction, the second clamping plate 4 has two first positioning protrusions (not shown in the figure) protruding from the end face of the cutting blade 2. The two first positioning protrusions are located on both sides of the cutting blade 2 along the third direction to restrict the movement of the cutting blade 2 along the third direction. It should be noted that the protrusion height of the first positioning protrusion needs to be greater than the wall thickness of the positioning recessed area 11, otherwise it cannot contact the cutting blade 2. Moreover, the protrusion height of the first positioning protrusion cannot be greater than the sum of the wall thickness of the positioning recessed area 11 and the thickness of the cutting blade 2, so as to prevent the first positioning protrusion from abutting against the first clamping plate 3, so that the first clamping plate 3 and the positioning plate 1 cannot clamp the cutting blade 2.

[0049] Of course, the second positioning protrusion on the first clamping plate 3 and the first positioning protrusion on the second clamping plate 4 can be set simultaneously, or only one of them can be set; there is no restriction here.

[0050] This overflow glue cutting device helps solve problems such as incomplete glue removal during manual trimming, leading to stringing or damage to plastic parts, and improves the yield and efficiency of glue trimming. Furthermore, by changing the positioning plate 1 to different sizes, it can be applied to products of different models and sizes, demonstrating strong applicability.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
