DETAILED DESCRIPTION

[0041] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] The chip removal device of the present invention is designed for products that require chip removal. It is used to remove chips from these products when the product processing is completed and at least some of the chips are still attached to the product, so that the product meets the relevant requirements. Figure 1In order to more clearly explain the principle and function of the chip removal device of the present invention, the product of the present invention takes the battery cover A as an example, and the chip removal device of the present invention is explained in detail in combination with the battery cover A. The battery cover A in this example includes a cover body A1, an explosion-proof disc mounting hole, a positive pole mounting hole and a negative pole mounting hole processed on the cover body A1, an explosion-proof disc A2 welded respectively in the explosion-proof disc mounting hole, the positive pole mounting hole and the negative pole mounting hole, and an insulating plate A5 arranged on the back side (the lower surface in the figure) of the cover body A1. The insulating plate A5 is respectively formed with perforations of corresponding shapes at the positions of the explosion-proof disc mounting hole, the positive pole mounting hole and the negative pole mounting hole; the insulating plate A5 is provided with a limiting protrusion A51 along its width direction on the side (the back side or the lower surface) facing away from the cover body A1, and the length of the limiting protrusion A51 is adapted to the width of the insulating plate A5. Each edge of the insulating plate A5 also extends away from the cover plate body A1 to form a raised edge A52. It should be understood that the structure and components of the battery cover plate A may vary depending on the implementation, and this document does not impose excessive limitations on the exemplary product structure. Machining these holes and welding the corresponding components will generate significant machining and welding debris.

[0045] See also Figure 2 The chip removal device of the embodiment of the present invention includes a housing 100, a clamping mechanism 200 disposed in the housing 100, and a chip removal mechanism 300 for blowing air toward the product clamped on the clamping mechanism 200 to remove the chips attached to the product. The clamping mechanism 200 is located below the chip removal mechanism 300 and is used to carry and clamp the product (hereinafter described as the battery cover A). The chip removal mechanism 300 includes a gas delivery unit (not shown) and a blowing unit connected to the gas delivery unit. The gas delivery unit includes an air pump and an air delivery pipeline. One end of the air delivery pipeline is connected to the air pump, and the other end is connected to the blowing unit.

[0046] See also Figure 3 and Figure 4 , the shell 100 can confine the scraps inside the shell 100, making it convenient to collect and process the scraps. The shell 100 is surrounded by a plurality of side walls, and a window 110 is formed on one side wall of the shell 100 (the front side wall in the figure) at a position corresponding to the clamping mechanism 200. The height of the window 110 can be determined based on ergonomics, so that workers can load and unload materials. A mounting crossbar 120 is laterally provided on the side wall at a position below the window 110, and the clamping mechanism 200 can be detachably mounted on the mounting crossbar 120. With this arrangement, when the clamping mechanism 200 needs to be installed / uninstalled, the clamping mechanism 200 can be installed / uninstalled without removing the shell 100, which makes use and maintenance more convenient.

[0047] A plurality of inner side surfaces of the housing 100 are detachably provided with an adhesion layer for adhering to debris, and the adhesion layer is a sticky plate 130. In each embodiment, the sticky plate 130 can be provided on the corresponding inner side surface of the housing 100 according to requirements. In this embodiment, a sticky plate 130 is provided on each of the inner side surface at the bottom of the housing 100 and the inner side surfaces of the two sides. The three sticky plates 130 are movably inserted into the housing 100 through the following structure: A "U" - shaped socket is formed on a side wall (the rear side wall in the illustration) of the housing 100 away from the window 110. The bottom horizontal socket 141 of the "U" - shaped socket is close to the bottom surface of the housing 100, and the two vertical sockets 142 are respectively close to the two side surfaces of the housing 100. The sticky plate 130 includes a sticky plate body 131 adapted to the shape of the corresponding inner side surface of the housing 100 and a baffle 132 provided on the outer end face of the sticky plate body 131. The width of the baffle 132 is greater than the width of the corresponding socket. When the sticky plate body 131 is inserted into the corresponding inner side surface of the housing 100, the baffle 132 is blocked outside the housing 100, which is convenient for taking out the sticky plate 130 during replacement. In order to hold the sticky plates 130 on the inner side surfaces of the two sides and prevent the sticky plates 130 from tipping or shifting, the above - mentioned mounting cross - column 120 is also used to limit the two side sticky plates 130 and hold the two side sticky plates 130. A card slot 133 capable of engaging with the mounting cross - column 120 is recessed outwardly at the position corresponding to the mounting cross - column 120 at the inner ends of the two side sticky plates 130. When assembling the three sticky plates 130, first insert the bottom sticky plate 130 horizontally into the inner side surface at the bottom of the housing 100 through the bottom horizontal socket 141, and then insert the two side sticky plates 130 into the inner side surfaces of the two sides through the two vertical sockets 142 until the card slots 133 of the two side sticky plates 130 are held on the mounting cross - column 120. With such a setting, the number of components can be reduced, the spatial layout can be made more reasonable, the manufacturing cost can be reduced, and it has the function of multi - purpose use. In some embodiments, the sticky plates 130 can also be movably inserted on the inner side surface at the bottom, the inner side surface at the top, the inner side surfaces of the two sides, and the inner side surface of a side relative to the window 110. Correspondingly, replacing the "U" - shaped socket with a "square" - shaped socket can meet the requirement of pasting sticky plates 130 on the inner side surface at the bottom, the inner side surface at the top, and the inner side surfaces of the two sides. By providing a linear socket on the top of the housing 100, the requirement of providing a sticky plate on the inner side surface of a side of the housing 100 away from the window 110 can be met. It should be understood that the above - mentioned setting method of the sticky plate 130 is only an exemplary description and should not be used to limit the assembly method of the adhesion layer in the debris - removing device of the present invention.

[0048] Please refer to Figures 5 to 7The clamping mechanism 200 includes a rotary drive unit 210, a rotary mounting unit 220 connected to the output shaft of the rotary drive unit 210, a first clamping unit 230 and a second clamping unit 240 vertically arranged at both ends of the rotary mounting unit 220. The horizontal positions of the first clamping unit 230 and the second clamping unit 240 are adapted to the height of the window 110, so that the first clamping unit 230 and the second clamping unit 240 can freely enter / exit the window 110 under the drive of the rotary drive unit 210. In the initial state, the first clamping unit 230 passes through the window 110 to be located on the outside of the shell 100; the second clamping unit 240 is located in the shell 100 at a position corresponding to the blowing unit. The design of the two clamping units and the rotary drive unit 210 makes this chip removal device a double-station chip removal device. When one of the clamping units is located at the position of the blowing unit to remove chips, the other clamping unit can clamp the product, achieving seamless connection and improving chip removal efficiency.

[0049] The rotary drive unit 210 can be a rotary cylinder, rotary motor, or the like. If the mounting post 120 is sufficiently wide, the rotary drive unit 210 can be directly secured to the mounting post 120. In this embodiment, to conserve materials and reduce costs, the mounting post 120 is not wide enough to fully secure the rotary drive unit 210. Therefore, a fixing base is provided inside the mounting post 120, to which the bottom end of the rotary drive unit 210 can be removably secured. Alternatively, the portion of the mounting post 120 used to secure the rotary drive unit 210 can be widened.

[0050] The rotating mounting unit 220 is an elongated structure as a whole, and includes a connecting portion 221 connected to the output shaft of the rotating driving unit 210, a first mounting arm 222 and a second mounting arm 223 symmetrically arranged on both sides of the connecting portion 221, and the first mounting arm 222 and the second mounting arm 223 are both formed with a hollow portion 224.

[0051] The first clamping unit 230 and the second clamping unit 240 are respectively arranged at the outer ends of the first mounting arm 222 and the second mounting arm 223. The first clamping unit 230 and the second clamping unit 240 each include a driving portion detachably connected to the corresponding mounting arm and a clamping portion connected to the output shaft of the driving portion. In this embodiment, the driving portion is a clamping cylinder 251 with an output shaft facing the product direction (upward). The clamping portion includes a first clamping finger 252 and a second clamping finger 253. The clamping cylinder 251 is used to drive the first clamping finger 252 and the second clamping finger 253 to move toward each other to clamp the two opposite sides of the limiting protrusion A51, and is also used to drive the first clamping finger 252 and the second clamping finger 253 to move away from the limiting protrusion A51. The first clamping finger 252 and the second clamping finger 253 both include a connecting seat 254 connected to the output shaft of the clamping cylinder 251, a first support finger 255 and a second support finger 256 arranged at both ends of the connecting seat 254 along the width direction of the battery cover A, the upper end surfaces of the first support finger 255 and the second support finger 256 are in contact with the side of the insulating plate A5 facing away from the cover body A1 for supporting the battery cover A, and the side of the first support finger 255 and the second support finger 256 facing the limiting protrusion A51 can clamp and release the limiting protrusion A51 under the drive of the clamping cylinder 251.

[0052] See also Figure 8In order to solve the technical problem that the first clamping fingers 252 and the second clamping fingers 253 block the corresponding portion of the battery cover A due to being in a stationary state during the chip removal process, resulting in poor chip removal effect on the corresponding portion of the battery cover A, the first clamping fingers 252 and the second clamping fingers 253 are opened at least once during the chip removal process. In order to ensure that the battery cover A remains stably placed on the first clamping fingers 252 and the second clamping fingers 253 during the process of the first clamping fingers 252 and the second clamping fingers 253, the following structure is designed: the connecting base is designed as a two-way cylinder 254a, the lower ends of the first support finger 255 and the second support finger 256 are respectively connected to the first output end 254b and the second output end 254c of the two-way cylinder 254a, and the outer side surfaces of the first support finger 255 and the second support finger 256 can be pressed against the inner side surface of the convex edge A52 of the insulating plate A5 under the drive of the two-way cylinder 254a. The principle of the above structure is as follows: first, the first clamping finger 252 and the second clamping finger 253 clamp the limiting protrusion A51 under the drive of the clamping cylinder 251, and the chip removal mechanism 300 blows air to the battery cover A to remove chips; secondly, the clamping cylinder 251 opens outward according to the internal processing logic (PLC controller), and at the same time, the first output end 254b and the second output end 254c of the two-way cylinder 254a move in opposite directions, so that the first support finger 255 and the second support finger 256 open outward and press the inner side of the protrusion A52 to prevent the battery cover A from shifting; again, the chip removal mechanism 300 continues to blow air to the battery cover A to remove chips. At this time, the chip removal mechanism 300 can remove chips from the part previously blocked by the first clamping finger 252 and the second clamping finger 253, and can remove chips from each part of the battery cover A more comprehensively to prevent residual chips. In the above embodiment, the clamping cylinder 251 and the bidirectional cylinder 254a are both electrically connected to a controller, and the controller is used to control the clamping cylinder 251 and the bidirectional cylinder 254a to perform corresponding actions according to the internal processing logic. The internal processing logic can set the opening action of the clamping cylinder 251 according to the requirements of different embodiments. For example, it can be set to control the clamping cylinder 251 to open after the chip removal mechanism 300 has worked for a first predetermined time; in the open state, after the chip removal mechanism 300 has worked for a second predetermined time, the clamping cylinder 251 is controlled to close to clamp the limiting protrusion A51, thereby completing the chip removal process of the battery cover A.

[0053] Please continue reading Figure 5The blowing unit is assembled on the top of the shell 100 through a fixing frame 310. The fixing frame 310 includes a connecting frame 311 connected to the top of the shell 100, an upper fixing part 312 connected to the lower end of the connecting frame 311, and a lower fixing part 313 arranged below the upper fixing part 312. The upper fixing part 312 and the lower fixing part 313 are respectively located above and below the product. The upper fixing part 312 and the lower fixing part 313 are both horizontal rod-shaped or plate-shaped structures. The lower fixing part 313 is connected to the upper fixing part 312 through a vertical rod / plate. The front end of the lower fixing part 313 is close to the first clamping finger 252 and the second clamping finger 253, and the horizontal position of the front end of the lower fixing part 313 is lower than the first clamping finger 252 and the second clamping finger 253 to make way for them.

[0054] See also Figure 9 and Figure 10 The air blowing unit includes an upper air blowing portion 320 formed above the product to remove debris from the upper surface of the product, and a lower air blowing portion 330 formed below the product to remove debris from the lower surface of the product. The upper air blowing portion 320 includes a first cavity 321 disposed in the upper fixing portion 312, a first air outlet assembly 322 formed on a side of the first cavity 321 facing the product, and a first air inlet 323 formed in the first cavity 321 and connected to the air delivery unit.

[0055] The shape of the first cavity 321 on the horizontal projection plane is adapted to the shape of the battery cover A. It includes a cavity body 321a with an opening formed in the direction of the product and a sealing plate 321b that is detachably sealed at the opening. The shape and size of the opening are adapted to the shape and size of the battery cover A. The first cavity 321 adopts a detachable setting to facilitate the processing of the first gas outlet component 322 and reduce the processing difficulty. The first gas outlet component 322 is formed on the sealing plate 321b. The first gas outlet component 322 includes three groups of first gas outlet holes 322a formed on the sealing plate 321b at three positions corresponding to the explosion-proof mounting hole, the positive pole mounting hole and the negative pole mounting hole, a plurality of second gas outlet holes spaced apart at each edge of the sealing plate 321b, and a reinforced gas outlet hole 322c formed between the second gas outlet hole 322b and the first gas outlet hole 322a on each side edge. Each group of first air outlet holes 322a is adapted to the corresponding hole shape and includes several independent holes distributed around the circumference of the corresponding hole shape. Each independent hole projects onto the horizontal plane as an arc-shaped hole, and the cross-sectional area of ​​each independent hole gradually increases from top to bottom. Specifically, the end walls of the hole can be gradually inclined outward from top to bottom, resulting in a trapezoidal longitudinal cross-section of the hole. The second air outlet holes 322b are tapered holes, with their aperture gradually increasing from top to bottom. This design expands the blowing range of each air outlet hole, fully covering the battery cover A and effectively removing debris from the battery cover A.

[0056] See also Figure 11 The lower blowing part 330 includes a second cavity 331, a second gas outlet assembly 332 formed on a side of the second cavity 331 facing the product, and a second gas inlet 333 formed on the second cavity 331 and connected to the gas delivery unit.

[0057] The second cavity 331 is a hollow cylindrical structure whose length matches the length of the battery cover A, including but not limited to a cylindrical shape, a square cylindrical shape, etc. The front end of the lower fixing portion 313 is formed with an assembly ring groove 313a whose shape matches the outer peripheral shape of the second cavity 331, and a notch is formed on the front upper side of the assembly ring groove 313a (towards the battery cover A). When assembling the second cavity 331 into the assembly ring groove 313a, the second cavity 331 is inserted into the assembly ring groove 313a along the axial direction of the assembly ring groove 313a, and the second cavity 331 is rotated so that the second gas outlet component 332 of the second cavity 331 faces the battery cover A. The second gas outlet component 332 located in the assembly ring groove 313a is aligned with the battery cover A through the notch.

[0058] The second air outlet component 332 includes a plurality of groups of third air outlet holes spaced apart along the length direction of the second cavity 331 on the side of the second cavity 331 facing the battery cover A. Each group of third air outlet holes is composed of a plurality of independent air outlet holes spaced apart around the circumference of the second cavity 331, and the number and distribution position of the independent air outlet holes are determined according to different product shapes, required chip removal areas, etc. The plurality of independent air outlet holes are distributed in a fan shape, that is, the inner ends of the plurality of independent air outlet holes extend infinitely and intersect at a central point, and the outer ends (air outlet ends) are radially spaced evenly around the periphery of the second cavity 331. Of course, the structure of each group of third air outlet holes can also be the same or similar to the first air outlet hole 322a, so that its cross-sectional area gradually increases from bottom to top (towards the product) to increase the blowing range.

[0059] See also Figure 12 , Figure 12 This is a flow chart of an embodiment of the chip removal method of the present invention. The chip removal method of this embodiment includes the following steps:

[0060] S100, product clamping: clamp the product on the clamping mechanism; wherein, please refer to Figure 13 ,This step includes the following sub-steps:

[0061] S110, clamping the product on the first clamping unit located outside the chip removal mechanism (i.e., outside the window of the housing);

[0062] In this step, the clamping cylinder drives the first and second clamping fingers to open outward, placing the limiting protrusion of the battery cover between the first and second clamping fingers. The clamping cylinder then drives the first and second clamping fingers inward to clamp the limiting protrusion. The opening and clamping strokes of the first and second clamping fingers can be programmed with corresponding stroke parameters in a PLC controller.
