[0015] The beneficial effects of the present invention are as follows: In view of the defects and deficiencies existing in the prior art, the present invention independently researches, develops and designs an automatic deburring machine for battery cell flanges after cutting, which realizes the linkage transfer and bearing of multiple battery cells, and the double-side synchronous deburring of multiple battery cells, effectively improving the deburring efficiency.

[0016] The present invention aims to provide an automatic deburring device applied to the manufacturing process of new energy batteries, which belongs to the equipment for automatically deburring the parts after cutting the cell flange. Its function is to automatically polish and deburr the parts after cutting the cell flange to ensure the surface flatness and smoothness of the flange cutting part. Specifically, the overall structure of the present invention uses a horizontally arranged machine table as the bearing structure. A bearing platform is erected along a straight line on the machine table. The bearing platform is a strip-shaped structure, which is erected on the machine table and has a double-layer structure. A plurality of bearing stations are evenly spaced on the upper layer of the bearing platform, used to simultaneously bear and adsorb and fix a plurality of cells to be deburred. The bearing stations adopt an open support structure, and the cells are adsorbed and fixed downward through vacuum negative pressure, so that the deburring mechanisms on both the front and rear sides can approach the flange cutting surfaces on both the front and rear sides of the cells at the same time; A receiving groove is correspondingly arranged below the bearing station, used to receive dust, waste materials, etc. dropped during the deburring process in real time. The receiving groove extracts and exports the received substances through a vacuum tube connected to the lower part; A linkage transfer mechanism is erected above the bearing platform. The linkage transfer mechanism is provided with multiple groups of transfer heads corresponding to multiple bearing stations, and drives the multiple groups of transfer heads to move horizontally and linearly above the bearing platform in a linkage manner; When the deburring of the cells on the bearing station is completed, the multiple groups of transfer heads synchronously take out the cells on the corresponding bearing stations below them respectively, and horizontally move the distance between two adjacent bearing stations. By repeating this process, the deburring of multiple cells is synchronized, and the cells can be successively deburred and polished at multiple bearing stations, effectively improving the deburring quality; In addition, the transfer head of the present invention also has the function of rotating and adjusting the angle. Since burr removal operations need to be performed on all four cutting edges of the cell flange, after completing the bilateral deburring in a single time, the transfer cylinder sucks the cell from the bearing station and then rotates the cell by 90°, and then places it on the bearing station to deburr the other two sides of the flange; This function of rotating and adjusting the deburring gap coordinates with the open support and adsorption method of the bearing platform for the cell to efficiently complete the deburring of the four sides of the cell flange, effectively improving the deburring efficiency. Specifically, the transfer head of the present invention uses a transfer connection seat vertically arranged on the transfer cross-frame as the support structure. A rotation motor with its output end facing downward is vertically arranged on the side wall of the transfer connection seat. The output end of the rotation motor is connected to a rotation shaft. The bottom of the rotation shaft is horizontally connected to a transfer support. A transfer suction block is horizontally arranged below the transfer support. The transfer suction block is spaced from the transfer support and is connected to the transfer support through a first spring column. During the process of taking and placing the cell, elastic buffering is provided by the first spring column, so that the transfer suction hole is in flexible contact with the cell, avoiding excessive extrusion of the cell surface during the process of taking and placing the cell, and preventing problems such as deformation of the cell surface; A plurality of vacuum suction holes are arranged at the bottom of the transfer suction block, and the cell is adsorbed and fixed upward through vacuum negative pressure during the process of taking and placing the cell.

[0017] Furthermore, a deburring mechanism is designed according to the special process requirements for deburring the cell flange in the present invention. The deburring mechanism includes multiple groups, which are respectively arranged on the front and rear sides of each loading station, realizing synchronous deburring of the cutting end faces on the front and rear sides of the cell flange and doubling the cutting efficiency. Specifically, the deburring mechanism of the present invention outputs linear power through a first linear module and a second linear module that are perpendicular to each other to drive the support slide to move linearly in the horizontal plane in the transverse and longitudinal directions. The third linear module vertically arranged on the support slide provides linear power in the vertical direction to drive the lifting movement of the box body connected to its output end. An installation space is provided inside the box body and a deburring component is arranged. A cover body is provided on the upper part of the box body. The deburring component extends upward into the cover body. One side of the cover body close to the loading platform is an open surface, so that the deburring component can approach the cell flange on the loading platform to perform the deburring action. The special feature is that the deburring component of the present invention realizes the synchronous linkage drive of the first brush and the second brush by outputting a single power, ensuring the synchronous rotation of the first brush and the second brush while reducing the power output, so as to improve the uniformity of the surface grinding during deburring. And while driving the first brush and the second brush to rotate synchronously, the first brush and the second brush rotate in opposite directions. Compared with the grinding method of the two rotating in the same direction, the reverse movement grinds the flange surface from both sides in the reverse direction, and the surface grinding is more uniform, which can effectively improve the grinding quality. Specifically, the deburring component uses a driving motor as the power output structure. The driving motor is hung on the horizontal partition inside the box body, and the output end passes through the partition upward and is connected with a synchronous pulley. The first rotating shaft and the second rotating shaft are arranged in parallel and at intervals on the top plate of the box body. The power output by the driving motor drives the first rotating shaft to rotate through a transmission belt. While the first rotating shaft rotates, it drives the second rotating shaft to rotate synchronously in the opposite direction through the transmission belt. The first rotating shaft and the second rotating shaft respectively drive the first brush and the second brush arranged on them to rotate synchronously in the opposite direction. The deburring of the surface is completed by the first brush and the second brush contacting the flange end wall and grinding on its surface.

[0018] Furthermore, the cell transfer arm of the present invention realizes the synchronous transfer of multiple cells through multiple groups of transfer arm heads. The special feature is that the mutual spacing between multiple groups of transfer arm heads is adjusted in real time through an adjustment component to adapt to production scenarios with different processing spacings or sizes. That is, one group of transfer arm heads is fixedly arranged on the lifting slide, and the other group of transfer arm heads is arranged on the adjustment slide. The adjustment cylinder drives the adjustment slide to drive the other group of transfer arm heads to move back and forth in a straight line direction to control the relative position between the two groups of transfer arm heads. Further, the transfer arm head of the present invention realizes the automatic picking and placing of cells by adopting a flexible contact method; specifically, the transfer arm suction block of the transfer arm head is supported by a flexible slide. The flexible slide is movably connected to the vertically arranged transfer arm support plate and is connected to the extension block horizontally extending above the transfer arm support plate through a second spring column; during the process of picking and placing cells, when the transfer arm suction block contacts the surface of the cell, elastic buffering is provided through the second spring column, so that the transfer arm suction block is in flexible contact with the surface of the cell to reduce the extrusion deformation of the cell and ensure the quality of the cell.

Among them, the adjustment cylinder 57 is arranged on the lifting slide 55 and outputs power in the linear direction; the adjustment slide 58 is slidably connected to the lifting slide 55 and is connected to the output end of the adjustment cylinder 57; the transfer arm head 56 includes a transfer arm support plate 561, an extension support block 562, a second spring column 563, a flexible slide 564 and a transfer arm suction block 565. Among them, the transfer arm support plate 561 is arranged on the lifting slide 55 or the adjustment slide 58; the extension support block 562 is horizontally arranged on the upper part of the side wall of the transfer arm support plate 561 and extends horizontally outwards; the flexible slide 564 is slidably connected to the side wall of the transfer arm support plate 561 in the vertical direction; the second spring column 563 is vertically arranged, and both ends of the second spring 563 are respectively connected to the extension support block 562 and the flexible slide 564 to provide elastic buffering; the transfer arm suction block 565 is horizontally arranged at the bottom of the flexible slide 564, and at least two vacuum suction nozzles are arranged at the bottom of the transfer arm suction hole 565 for adsorbing and fixing the battery cell.

[0051] The cell transfer arm 5 of the present invention realizes the synchronous transfer of multiple cells through multiple sets of transfer arm heads 56. The special feature is that the mutual spacing between multiple sets of transfer arm heads 56 is adjusted in real time through an adjustment component to adapt to production occasions with different processing spacings or sizes. That is, one set of transfer arm heads 56 is fixedly arranged on the lifting slide seat 55, and the other set of transfer arm heads 56 is arranged on the adjustment slide seat 58. The adjustment cylinder 57 drives the adjustment slide seat 58 to drive the other set of transfer arm heads 56 to move back and forth in a straight line direction to control the relative position between the two sets of transfer arm heads 56. Further, the transfer arm head 56 of the present invention realizes the automatic picking and placing of cells in a flexible contact manner. Specifically, the transfer arm suction block 565 of the transfer arm head 56 is supported by a flexible slide seat 564. The flexible slide seat 564 is movably connected to the vertically arranged transfer arm support plate 561 and is connected to the extension block 562 extending horizontally above the transfer arm support plate 561 through the second spring column 562. During the process of picking and placing cells, when the transfer arm suction block 565 contacts the surface of the cell, elastic buffering is provided through the second spring column 563, so that the transfer arm suction block 565 is in flexible contact with the surface of the cell to reduce the extrusion deformation of the cell and ensure the quality of the cell.

[0052] Furthermore, the present invention designs an automatic deburring machine for a battery cell flange after cutting, which can realize the linkage handling and loading of multiple battery cells, and the bilateral synchronous deburring of multiple battery cells, effectively improving the deburring efficiency. The present invention aims to provide an automatic deburring device applied to the manufacturing process of new energy batteries, belonging to the automatic deburring equipment after the battery cell flange is cut. Its function is to automatically polish and deburr the parts after the battery cell flange is cut to ensure the surface flatness and smoothness of the flange cutting part. Specifically, the overall structure of the present invention uses a horizontally arranged machine table as the loading structure. A loading platform is erected along a straight line on the machine table. The loading platform is a strip-shaped structure, which is erected on the machine table and is a double-layer structure. A plurality of loading stations are evenly spaced on the upper layer of the loading platform, which are used to simultaneously load and adsorb and fix multiple battery cells to be deburred. The loading stations adopt an open support structure, and the battery cells are adsorbed and fixed downward through vacuum negative pressure, so that the deburring mechanisms on both sides can approach the flange cutting surfaces on both sides of the battery cell at the same time; A receiving groove is correspondingly arranged below the loading station, which is used to receive dust, waste materials, etc. dropped during the deburring process in real time. The receiving groove extracts and exports the received substances through a vacuum tube connected to the lower part; A linkage transfer mechanism is erected above the loading platform. The linkage transfer mechanism is provided with multiple groups of transfer heads corresponding to multiple loading stations, and drives multiple groups of transfer heads to move horizontally and linearly above the loading platform in a linkage manner; When the deburring of the battery cells on the loading station is completed, multiple groups of transfer heads synchronously take out the battery cells on the corresponding loading stations below them and horizontally move the distance between two adjacent loading stations. In this way, the deburring of multiple battery cells is realized synchronously, and the battery cells can be gradually deburred and polished on multiple loading stations one by one, effectively improving the deburring quality; In addition, the transfer head of the present invention also has the function of rotating and adjusting the angle. Since burr removal operations need to be performed on all four cutting edges of the battery cell flange, after the bilateral deburring is completed once, the transfer cylinder sucks the battery cell from the loading station and then rotates the battery cell by 90°, and then places it on the loading station to deburr the other two sides of the flange; This function of rotating and adjusting the deburring gap coordinates with the open support and adsorption method of the loading platform for the battery cells to efficiently complete the deburring of the four sides of the battery cell flange, effectively improving the deburring efficiency. Specifically, the transfer head of the present invention uses a transfer connection seat vertically arranged on the transfer cross frame as the support structure. A rotary motor with its output end facing downwards is vertically arranged on the side wall of the transfer connection seat. The output end of the rotary motor is connected to a rotary shaft. The bottom of the rotary shaft is horizontally connected to a transfer support. A transfer suction block is horizontally arranged below the transfer support. The transfer suction block is spaced from the transfer support and is connected to the transfer support through a first spring column. During the process of taking and placing the battery cell, elastic buffering is provided by the first spring column, so that the transfer suction hole is in flexible contact with the battery cell, avoiding excessive extrusion of the battery cell surface during the process of taking and placing the battery cell, and problems such as deformation of the battery cell surface; A plurality of vacuum suction holes are arranged at the bottom of the transfer suction block, and the battery cell is adsorbed and fixed upward through vacuum negative pressure during the process of taking and placing the battery cell.

[0053] Furthermore, a deburring mechanism is designed according to the special process requirements for deburring the cell flange of the present invention. The deburring mechanism includes multiple groups, which are respectively arranged on the front and rear sides of each loading station, realizing synchronous deburring of the cutting end faces on the front and rear sides of the cell flange and doubling the cutting efficiency. Specifically, the deburring mechanism of the present invention outputs linear power through a first linear module and a second linear module that are perpendicular to each other to drive the support slide to move linearly in the horizontal plane in the transverse and longitudinal directions. The third linear module vertically arranged on the support slide provides linear power in the vertical direction to drive the lifting movement of the box body connected to its output end. An installation space is provided inside the box body and a deburring component is provided. A cover body is provided on the upper part of the box body. The deburring component extends upward into the cover body. The side of the cover body close to the loading platform is an open surface, so that the deburring component can approach the cell flange on the loading platform for deburring operations. The special feature is that the deburring component of the present invention realizes synchronous linkage driving of the first brush and the second brush by outputting a single power, ensuring the rotational synchronism of the first brush and the second brush while reducing power output to improve the uniformity of surface grinding during deburring. And while driving the first brush and the second brush to rotate synchronously, the first brush and the second brush rotate in opposite directions. Compared with the grinding method of the two moving in the same direction, the reverse movement grinds the flange surface from both side directions in the reverse direction, and the surface grinding is more uniform, which can effectively improve the grinding quality. Specifically, the deburring component uses a driving motor as the power output structure. The driving motor is hung on the horizontal partition inside the box body, and the output end passes through the partition upward and is connected with a synchronous pulley. On the top plate of the box body, a first rotating shaft and a second rotating shaft are arranged in parallel at intervals. The power output by the driving motor drives the first rotating shaft to rotate through a transmission belt. While the first rotating shaft rotates, it drives the second rotating shaft to rotate synchronously in the opposite direction through the transmission belt. The first rotating shaft and the second rotating shaft respectively drive the first brush and the second brush arranged on them to rotate synchronously in the opposite direction. The deburring of the surface is completed by the first brush and the second brush contacting the flange end wall and grinding on its surface.
