[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, the present application proposes a laser induced sintering processing device, including a turntable module 100, the turntable module 100 includes a rotary drive mechanism 120 and a plurality of carriers 110 connected to the rotary drive mechanism 120, the carrier 110 is used to carry battery cells, the laser induced sintering processing device has a processing station B and a material unloading station C sequentially arranged along the rotation path of the rotary drive mechanism 120, an electric input module 200 and a laser processing module 300 are arranged corresponding to the processing station B, the laser processing module 300 is used to emit a laser beam to scan the battery cell while a reverse voltage is applied to the battery cell through the electric input module 200, and the rotary drive mechanism 120 is used to drive the plurality of carriers 110 to sequentially pass through the processing station B and the material unloading station C;

[0038] The corresponding unloading station C is provided with an unloading conveying mechanism 410 and an unloading rotating conveying arm 420. Figure 3 As shown, the unloading rotary transport arm 420 includes a first rotary drive actuator (not shown in the figure), a first rotary arm 422 connected to the first rotary drive actuator, and a first suction cup 423 connected to the end of the first rotary arm 422. The unloading rotary transport arm 420 is located above the carrier 110, and the first rotary drive actuator is used to drive the first suction cup 423 to move back and forth between the unloading station C and the unloading conveying mechanism 410.

[0039] A first placement position E is provided on the side of the unloading conveying mechanism 410, and the first placement position E is located on the rotation path of the unloading rotating conveying arm 420. A first carrier 500 is provided at the first placement position E. The first carrier 500 is used to carry defective battery cells or cache battery cells. The first rotating driving actuator is also used to drive the first suction cup 423 to move back and forth between the unloading station C and the first carrier 500.

[0040] Preferably, when the first carrier 500 is used to carry defective battery cells, before the unloading rotating transport arm 420 unloads the battery cells to the unloading conveying mechanism 410, the battery cells are photographed by a visual positioning mechanism such as a CCD camera to identify whether the battery cells are damaged. For example, a visual positioning mechanism is set at the loading station A, which can not only check whether there is any damage, but also photograph the battery cells so that the electrodes in the electric input module 200 can adjust their positions according to the photographing results so that the electrodes in the electric input module 200 are aligned with the positions where the battery cells need to contact.

[0041] The rotary drive mechanism 120 may be a motor, such as a DD motor. Furthermore, the turntable module 100 further includes a horizontally arranged and centrally symmetrical support frame. The drive shaft of the rotary drive mechanism 120 is vertically arranged and connected to the center of the support frame. A plurality of carriers 110 are connected to the rotary drive mechanism 120 by being installed on the support frame, and each carrier 110 is at an equal distance from the center of the support frame. Specifically, the unloading station C and the processing station B (as well as the loading station A described below) refer to a spatial position. The rotary drive mechanism 120 will drive the carrier 110 to pass through these stations in sequence, and stop at the corresponding station to perform corresponding operations when necessary. For example, unloading station C refers to the station where the battery cells are unloaded and moved off the carrier 110. When the carrier 110 moves to the position of unloading station C, the unloading rotating transport arm 420 can move the battery cells on the carrier 110. Processing station B is the station where the battery cells are contacted by the electric input module 200 and laser scanned and processed by the laser processing module 300. The electric input module 200 and the laser processing module 300 are arranged at the location of this station. When the carrier 110 moves to the position of processing station B, the electric input module 200 contacts the battery cells and applies a reverse voltage to the battery cells while the laser beam scans the battery cells to process the battery cells.

[0042] Among them, the electric input module 200 includes a first electrode and a second electrode, and the first electrode and the second electrode are respectively used to connect to the positive electrode and the negative electrode of the power supply, and are also respectively used to electrically contact the positive electrode and the negative electrode of the battery cell, so as to apply a reverse voltage to the battery cell through the first electrode and the second electrode. The specific position and structure of the first electrode and the second electrode can be found in the detailed description below. Generally, the laser processing module 300 is located above the carrier platform 110. The laser processing module 300 at least includes a laser for emitting a laser beam and a laser scanning mechanism for controlling the scanning direction of the laser beam. The common laser scanning mechanism is composed of a galvanometer plus a field mirror. According to actual needs, the laser processing module 300 can also include other required optical devices. The laser processing module 300 is generally also located above the first electrode and the second electrode.

[0043] In the embodiment of the present application, the unloading conveying mechanism 410 can be a conveyor belt, and the first rotary drive actuator is a motor. When unloading is required, the first rotary drive actuator drives the first suction cup 423 to move to above the carrier platform 110 corresponding to the unloading station C, sucks the processed battery cells, and then the first rotary drive actuator drives the first suction cup 423 to rotate above the unloading conveying mechanism 410, places the battery cells on the unloading conveying mechanism 410, and completes the unloading. Among them, in the embodiment of the present application, the first rotating arm 422 is a straight-line motion arm. By setting the unloading rotating transport arm 420 to a rotary drive form, its operating speed is faster, which can improve production capacity, especially relative to the linear moving transport structure.

[0044] Among them, the first carrier 500 can be a material box, or a carrier plate or a carrier table, as long as it is a device that can carry battery cells. Preferably, the first carrier 500 is a material box. By setting the first placement position E on the side of the unloading conveying mechanism 410 and setting the first carrier 500 at the first placement position E, defective battery cells such as broken pieces in the processing process can be placed in the first carrier 500. Of course, if the unloading and loading beats do not match and the battery cells transmitted by the loading need to be cached, the battery cells can also be cached in the first carrier 500. By setting the first placement position E on the rotation path of the unloading rotary conveying arm 420, a unloading rotary conveying arm 420 can not only transport the battery cells to the unloading conveying mechanism 410 but also transport the battery cells to the first placement position E, which saves costs and has a simple structure.

[0045] As another example, Figure 1 , Figure 2 As shown, the unloading conveying mechanism 410 is a conveying belt, and the unloading station C, the unloading conveying mechanism 410, and the first placement position E are arranged in a triangle. The triangular arrangement is convenient for conveying and carrying the battery cells, and the three are not arranged in a colinear manner. Specifically, as Figure 1 As shown, the unloading station C, the unloading conveying mechanism 410, and the first placement position E are in the form of an isosceles right triangle, and the unloading conveying mechanism 410 is located at the right angle point. When the first suction cup 423 in the unloading rotary conveying arm 420 is located above the supporting platform 110 corresponding to the unloading station C, the unloading rotary conveying arm 420 rotates 90° clockwise, and the first suction cup 423 moves from the unloading station C to the unloading conveying mechanism 410; when the first suction cup 423 in the unloading rotary conveying arm 420 is located above the supporting platform 110 corresponding to the unloading station C, the unloading rotary conveying arm 420 rotates 180° clockwise, and the first suction cup 423 moves from the unloading station C to the first placement position E. It should be noted that, for the convenience of control, it is considered that the three are roughly in the form of an isosceles right triangle, and it is also acceptable if they are not strictly isosceles right triangles. The positions of the three can be arranged according to actual needs, as long as the three are located on the rotation path of the unloading rotary conveying arm 420. Figure 2As shown, the unloading station C, the unloading conveying mechanism 410, and the first placement position E are in the form of an equisceles acute triangle. The unloading station C is located on the perpendicular midline of the line connecting the unloading conveying mechanism 410 and the first placement position E. When the first suction cup 423 in the unloading rotary conveying arm 420 is located above the supporting platform 110 corresponding to the unloading station C, the unloading rotary conveying arm 420 rotates 90° clockwise, and the first suction cup 423 moves from the unloading station C to the unloading conveying mechanism 410. Conversely, the unloading rotary conveying arm 420 rotates 90° counterclockwise, and the first suction cup 423 moves from the unloading station C to the first placement position E. It should also be noted that, for the convenience of control, it is considered that the three are roughly in the form of an isosceles acute triangle, and it is also acceptable if it is not a strict isosceles triangle. The positions of the three can be arranged according to actual needs, as long as the three are located on the rotation path of the unloading rotary conveying arm 420, that is, as long as one unloading rotary conveying arm 420 can rotate and move back and forth between the three to achieve the corresponding function.

[0046] It should be noted that, in other embodiments, taking into account other needs or work station arrangements, the unloading rotating transport arm 420 can also be considered as an L-shaped rotating arm, which is set according to actual conditions. When it is an L-shaped rotating arm, suction cups are provided at both ends of the L-shaped rotating arm, which means that two battery cells in a vertical relationship can be sucked or put down at the same time.

[0047] As another example, Figure 1 , Figure 2 As shown, a loading station A is also provided on the rotating path of the rotary drive mechanism 120. The rotary drive mechanism 120 drives the carrier 110 to pass through the loading station A, the processing station B, and the unloading station C in sequence. It should be noted that each time, multiple carriers 110 rotate simultaneously; a loading conveying mechanism 610 is provided corresponding to the loading station A. The loading conveying mechanism 610 is a conveying belt, and the unloading conveying mechanism 410 is a conveying belt. The loading conveying mechanism 610 and the unloading conveying mechanism 410 are both arranged along a first direction and both convey battery cells along the first direction. The loading station A and the unloading station C are arranged along a second direction. The second direction coincides with or is parallel to the first direction. The first direction is, for example, Figure 1 In the X-axis direction. Specifically, Figure 1 As shown, the second direction coincides with the first direction. At this time, the loading conveying mechanism 410, the loading station A, the unloading station C, and the unloading conveying mechanism 610 are basically arranged in a straight line. Figure 2 As shown, the second direction is parallel to the first direction. By arranging the loading conveying mechanism 610 and the unloading conveying mechanism 410 in the same line, the battery cells are continuously conveyed online, and the transmission efficiency is higher.

[0048] As another embodiment, a loading station A is further provided on the rotation path of the rotary drive mechanism 120, and the rotary drive mechanism 120 drives the carrier 110 to pass through the loading station A, the processing station B, and the unloading station C in sequence; a positioning station is also provided on the rotation path of the rotary drive mechanism 120, and a visual positioning mechanism 900 is provided at the positioning station, and the visual positioning mechanism 900 is provided above or below the carrier 110, such as Figure 4 In one embodiment shown, the visual positioning mechanism 900 is arranged below the carrier 110. The location of the positioning station can be multiple. For example, the positioning station and the loading station A are the same station. In this case, the carrier 110 passes through the loading station A, the processing station B, and the unloading station C in sequence; or the positioning station is arranged between the loading station A and the processing station B. In this case, the carrier 110 passes through the loading station A, the positioning station, the processing station B, and the unloading station C in sequence. The visual positioning mechanism 900 can be a CCD camera. By setting the visual positioning mechanism 900, the information of the battery cell itself on the carrier 110 (for example, whether it is broken, etc.) and the position information of the grid line or PAD point on the battery cell can be obtained, so that the electrode in the electric input module 200 can align and contact the battery cell according to the position information obtained by taking a photo of the battery cell.

[0049] Furthermore, the number of the carriers 110 is four, the positioning station and the loading station A are the same station; the station between the loading station A and the processing station B is a spare function station D, such as Figure 1 As shown, the spare function position D can be used for other functions, such as a sheet dropping station; or two processing stations B are included between the loading station A and the unloading station C. At this time, the two processing stations B respectively have an electrical input module 200. By setting up two processing stations B for joint processing, work efficiency can be improved.

[0050] As another embodiment, a loading station A is also provided on the rotation path of the rotary drive mechanism 120, and the rotary drive mechanism 120 drives the carrier 110 to pass through the loading station A, the processing station B, and the unloading station C in sequence; a loading conveying mechanism 610 and a loading rotary transport arm 620 are provided corresponding to the loading station A, and the loading rotary transport arm 620 includes a second rotary drive actuator, a second rotary arm connected to the second rotary drive actuator, and a second suction cup connected to the end of the second rotary arm. The loading rotary transport arm 620 is located above the carrier 110, and the second rotary drive actuator is used to drive the second suction cup to move back and forth between the loading station A and the loading conveying mechanism 610. Similarly, the second rotary transport arm 620 is also set to a rotary drive form, and its operation speed is faster, which can improve production capacity.

[0051] As another example, Figure 1 and Figure 2As shown, both the loading rotating transport arm 620 and the unloading rotating transport arm 420 are I-shaped moving arms, which can meet the transport requirements and increase the transport speed.

[0052] As another embodiment, a loading station A is also provided on the rotation path of the rotating drive mechanism 120, and a loading conveying mechanism 610 and a loading rotating conveying arm 620 are provided corresponding to the loading station A. The loading rotating conveying arm 620 includes a second rotating drive actuator, a second rotating arm connected to the second rotating drive actuator, and a second suction cup connected to the end of the second rotating arm. The loading rotating conveying arm 620 is located above the carrier 110. The structure of the loading rotating conveying arm 620 can be the same as that of the unloading rotating conveying arm 420. In order to prevent the pattern direction of the battery cell from changing when the battery cell is transferred from the loading conveying mechanism 610 to the carrier 110 corresponding to the loading station A by the loading rotating conveying arm 620, or in order to prevent the pattern direction of the battery cell from changing when the battery cell is transferred from the carrier 110 corresponding to the unloading station C by the unloading rotating conveying arm 420 to the unloading conveying mechanism 410, the loading rotating conveying arm 620 or the unloading rotating conveying arm 420 also includes a transmission module; wherein, Figure 3 As shown, the transmission module includes a first synchronous wheel 810, a second synchronous wheel 820 and a synchronous belt 830 that is simultaneously sleeved on the first synchronous wheel 810 and the second synchronous wheel 820. The first synchronous wheel 810 is fixed, and the second synchronous wheel 820 is rotationally connected to the first rotating arm 422 or the second rotating arm.

[0053] The first synchronous wheel 810 is fixed and does not move means that the first synchronous wheel 810 is fixedly connected to a base. For example, when the unloading rotary transport arm 420 includes a transmission module, the first synchronous wheel 810 is stationary when the first rotating arm 422 moves under the drive of the first rotating drive actuator. When the loading rotary transport arm 620 includes a transmission module, the meaning of the first synchronous wheel 810 being fixed and does not move is similar. The following example takes the unloading rotary transport arm 420 including a transmission module as an example. Figure 3 As shown, at this time, the second synchronous wheel 820 is rotatably connected with the first rotating arm 422. When the first rotating arm 422 rotates under the drive of the first rotating drive actuator, for example, when it rotates 90° clockwise, since it includes a transmission module, the first suction cup 423 rotates 90° counterclockwise under the action of the transmission module, thereby preventing the direction of the pattern on the battery cell from changing. When the feeding rotating transport arm 620 includes a transmission module, the principle is the same. The principle of this transmission module is prior art and will not be repeated here.

[0054] It should be noted that when the number of the supporting platforms 110 is four, since one of the loading rotating conveying arm 620 or the unloading rotating conveying arm 420 includes a transmission module, when the battery cell is rotated 90° from the loading conveying mechanism 610 through the loading rotating conveying arm 620 and transported to the supporting platform 110 corresponding to the loading station A, the rotating driving mechanism 120 rotates the supporting platform 110 three times and then moves to the unloading station C, and then the unloading rotating conveying arm 420 rotates 90° and transports it to the unloading conveying mechanism 410, the pattern direction on the battery cell does not change.

[0055] As another aspect of the present application, a laser induced sintering processing device is also proposed, such as Figure 5 As shown, the turntable module 100 includes a rotary drive mechanism 120 and a plurality of carriers 110 connected to the rotary drive mechanism 120, the carrier 110 is used to carry the battery cell, the laser induced sintering processing device has a loading station A and a processing station B arranged in sequence along the rotation path of the rotary drive mechanism 120, and an electric input module 200 and a laser processing module 300 are arranged corresponding to the processing station B, the laser processing module 200 is used to emit a laser beam to scan the battery cell while a reverse voltage is applied to the battery cell through the electric input module 300, and the rotary drive mechanism 120 is used to drive the plurality of carriers 110 to pass through the loading station A and the processing station B in sequence; the loading station A is provided with a loading conveying mechanism 610 and a loading and rotating conveying arm 620, the loading and rotating conveying arm 620 includes a second rotary drive actuator, a second rotating arm connected to the second rotary drive actuator, and a second suction cup connected to the end of the second rotating arm, the loading and rotating conveying arm is located above the supporting platform 110, the second rotary drive actuator is used to drive the second suction cup to move back and forth between the loading station A and the loading and conveying mechanism 610; and a second placement position F is provided on the side of the loading and conveying mechanism 610, and the second placement position F is located on the rotation path of the loading and rotating conveying arm 620, and a second supporting member 1000 is provided at the second placement position F, and the second rotary drive actuator is also used to drive the second suction cup to move back and forth between the loading station A and the second supporting member 1000. Among them, the structure under this embodiment is the same as that of the above embodiment, and the difference lies in the position of the second placement position F and the second carrier 1000. The second carrier 1000 can also be used to carry defective battery cells or cache battery cells. It is also different from the above embodiment in that when the second carrier 1000 is used to carry defective battery cells, before the loading rotating transport arm 620 obtains the battery cells on the loading conveying mechanism 610, the battery cells are photographed by a visual positioning mechanism such as a CCD camera to identify whether the battery cells are damaged. For example, a visual mechanism is set above the loading conveying mechanism 610.

[0056] Furthermore, the loading conveying mechanism 610 is a conveying belt, and the loading station A, the loading conveying mechanism 610 and the second placement position F can also be arranged in a triangle. The specific layout thereof refers to the above embodiment and will not be repeated here.

[0057] As another example, Figure 1 , Figure 2 As shown, a cache module is also provided at the rear of the unloading conveying mechanism 410, and the cache module includes a first material box 710, a second material box 720 and a cache transport mechanism 730 located above the two material boxes. The first material box 710 is used to place multiple sheets of separator paper stacked together, and the second material box 720 is used to stack and place separator paper and battery cells, that is, one battery cell is stacked with one separator paper in the vertical direction; the cache transport mechanism 730 includes a cache transport actuator (not numbered in the figure) and at least one cache transport suction cup 731 connected to the cache transport actuator, and the cache transport actuator drives the cache transport suction cup 731 to move back and forth between the unloading conveying mechanism 410, the first material box 710 and the second material box 720. By setting the cache module, the laser induced sintering processing device has both the first carrier 500 and the cache module. At this time, the first carrier 500 can be used to place bad battery cells, and the cache module can be used to place good battery cells that need to be cached (for example, due to mismatched loading and unloading rhythms or other needs). The structure is set at two different positions to make the device function more perfect. In addition, considering that when the processed battery cell is a back-contact battery cell, in order to avoid damaging the battery cell, adjacent battery cells need to be separated by spacers during caching. Therefore, two material boxes are set in the cache module. When one number of second material boxes 720 is not enough, several more second material boxes 720 can be set. Specifically, when working, the cache handling suction cup 731 first sucks a piece of spacer paper in the first material box 710 and then moves to the second material box 720 and puts the spacer paper into the second material box 720. Then the cache handling suction cup 731 puts the battery cell on the unloading conveying mechanism 410 into the second material box 720 above the spacer paper already placed, and repeats it in sequence.

[0058] Furthermore, in order to improve work efficiency, as another embodiment, the number of the cache transport suction cups 731 is two, and the two cache transport suction cups 731 work simultaneously, one of the cache transport suction cups 731 is used to take and place the spacer paper, and the other suction cup is used to take and place the battery cell. For the convenience of description, one of the cache handling suction cups 731 is called the first cache suction cup, and the other cache handling suction cup 731 is called the second cache suction cup. Specifically, during operation, the first cache suction cup sucks the battery cells to be cached conveyed from the unloading conveying mechanism 410, and the second cache suction cup puts the pre-absorbed spacer paper into the second material box 720; then the cache handling actuator drives the first cache suction cup and the second cache suction cup to move simultaneously, the first cache suction cup moves to the top of the second material box 720 to place the battery cells above the spacer paper in the second material box 720, and the second cache suction cup moves to the first material box 710 to suck the spacer paper in the first material box 710; then the cache handling actuator drives the first cache suction cup and the second cache suction cup to move simultaneously, the first cache suction cup returns to the top of the unloading conveying mechanism 410 again, and the second cache suction cup returns to the top of the second material box 720, and this process is repeated, so that multiple battery cells can be cached and placed in the second material box 720, and the second material box 720 stores the spacer paper and battery cells that are stacked in sequence.

[0059] Furthermore, if Figure 1 and Figure 2 As shown, preferably, the unloading conveying mechanism 410 includes a first conveying section and a second conveying section which are arranged in sequence, that is, after the battery cells are transferred to the unloading conveying mechanism 410, they first pass through the first conveying section and then pass through the second conveying section, wherein the second conveying section is arranged in the same line as the first material box 710 and the second material box 720, and the cache conveying mechanism is a linear conveying mechanism. By dividing the unloading conveying mechanism 410 into two sections, automatic control is more convenient; by setting the cache conveying mechanism as a linear conveying mechanism, the conveying structure is simple.

[0060] As another embodiment, the electrical input module 200 includes a first electrode and a second electrode, which are respectively used to connect to the positive and negative electrodes of the power supply, and are also respectively used to electrically contact the positive electrode and negative electrode of the battery cell; generally, the laser processing module 300 is located above the carrier 110.

[0061] It should be noted that the first electrode and the second electrode are respectively used to connect to the positive and negative electrodes of the power supply, which does not mean that the first electrode can only be connected to the positive electrode of the power supply. The first electrode can be connected to the positive or negative electrode of the power supply. When the first electrode is connected to the positive electrode of the power supply, the second electrode is connected to the negative electrode of the power supply. At this time, the first electrode is electrically contacted with the positive electrode of the battery cell, and the second electrode is electrically contacted with the negative electrode of the battery cell; when the first electrode is connected to the negative electrode of the power supply, the second electrode is connected to the positive electrode of the power supply, the first electrode is electrically contacted with the negative electrode of the battery cell, and the second electrode is electrically contacted with the positive electrode of the battery cell.

[0062] Among them, considering that the battery cell carried on the carrier 110 can be either a double-sided battery (the positive electrode and the negative electrode on the battery cell are respectively located on the front and back of the battery cell) or a back-contact battery (the positive electrode and the negative electrode are both located on the back of the battery cell), the first electrode and the second electrode can be arranged in various positions and specific structures. For example, the first type: the first electrode and the second electrode are both located below the carrying surface of the carrier 110 or are both located above the carrier 110. This situation is suitable for back-contact batteries. At this time, the first electrode and the second electrode can both be probes to contact the grid lines or PAD points on the battery cell, such as Figure 4 As shown, the first electrode and the second electrode are both located below the carrying surface of the carrier 110, that is, the positive electrode and the negative electrode on the battery cell are both located on the back of the battery cell, and the battery surface faces the laser processing module 300; or the second type: the first electrode is located above the carrier 110, and the second electrode is arranged on the carrier 110. This situation is suitable for double-sided batteries. At this time, the structure of the first electrode includes a probe row structure (that is, a plurality of collinearly arranged probes are connected under a probe bracket, and the plurality of probes are contacted with the battery cell), or a conductive wire, or a long strip of electrode sheet (the electrode sheet and the battery cell can be in surface contact), etc., and the second electrode is preferably a conductive plate; or the third type: the first electrode is located above the carrier 110, and the second electrode is located below the carrying surface of the carrier 110. This situation is suitable for double-sided batteries. At this time, the structure of the first electrode includes a probe row structure, or a conductive wire, or a long strip of electrode sheet, and the structure of the second electrode is the same as that of the first electrode, or is a conductive plate. It should be noted that when the first electrode or the second electrode is located below the carrying surface of the carrying platform 110, the carrying platform 110 needs to be partially hollowed out so that the first electrode and the second electrode pass through the hollowed-out portion to contact the back electrode of the battery cell.
