Description

Technical Field

[0001] The present application relates to the field of transport devices, and in particular to a transport robot and battery production equipment. Background Art

[0002] During the battery production process, the battery cells need to be strictly tested to ensure the quality of the power battery. Among them, the OCV test is a test of the open circuit voltage, AC internal resistance and shell voltage of the battery cell. During the OCV test of the battery cell, the logistics line first delivers the tray loaded with multiple battery cells to the loading position, and then the material picking robot picks up the battery cell from the tray and moves the battery cell to the test station to test the battery cell one by one.

[0003] Multiple battery cells in the tray are stacked and placed in a stacked manner. Since the surface of the battery cells is smooth, the surfaces of adjacent battery cells are in close contact, so that the air between them is expelled, thus forming a low-pressure area. The surrounding atmospheric pressure is relatively high, and the adjacent battery cells are adsorbed together under the effect of atmospheric pressure. When the retrieving robot picks up the battery cells for subsequent testing, it will take away the adjacent battery cells, resulting in the omission of the battery cells in subsequent testing. In addition, the vibration generated in the process of moving the battery cells may cause the adsorbed battery cells to fall, causing quality problems. Utility Model Content

[0037] Embodiment 1

[0038] See Figures 1 to 4 As shown, the transport manipulator provided by the present application can be used to load the battery cell 102 onto the test station for OCV2 detection.

[0039] The specific process of OCV2 detection is as follows: First, the logistics line delivers the tray 101 carrying the battery cell 102 to the loading position of the OCV2 test equipment. After the equipment automatically positions the tray 101, the barcode on the tray 101 can be scanned to obtain the process information of the tray 101, thereby achieving the purpose of process foolproofing and obtaining the information of the battery cell 102. Then, the transport robot picks up 6 battery cells 102 from the tray 101 at the same time and transfers them to the test station. After the battery cell 102 is positioned, scanned and OCV2 tested, it is transferred to the unloading conveyor line by the transport robot. Among them, NG battery cells 102 (NG battery cells 102 include the following types: ① OCV2 voltage is poor; ② IR is poor; ③ k value is poor, and different types are placed separately) are transferred to the NG collection box. Good battery cells 102 are unloaded into the tray 101, and the battery cell 102 information is re-bound to the tray 101 (unloading scans the barcode of the tray 101). The device automatically generates various parameter information of the battery cell 102, and the software can automatically generate corresponding statistical tables and charts for each parameter information for easy query.

[0040] The transport manipulator provided in the present application includes a picking mechanism 103 and a blowing mechanism 104. The picking mechanism 103 can be connected to the manipulator arm of the transport manipulator to pick up the battery cell 102 in the tray 101; the picked-up surface of the battery cell 102 is the large surface on one side of the thickness direction of the battery cell 102, that is, the surface formed by the long side and the wide side of the battery cell 102. Driven by the manipulator arm, the picking mechanism 103 can transfer the battery cell 102 to the loading position for subsequent testing of the battery cell 102.

[0041] The blowing mechanism 104 is connected to the picking mechanism 103. The blowing mechanism 104 is located on the side of the battery cell 102, and the blowing port of the blowing mechanism 104 is opposite to the side of the battery cell 102 that is away from the picking mechanism 103. When the picking mechanism 103 picks up the upper battery cell 102 from the tray 101, the picked-up surface of the battery cell 102 is the top surface of the upper battery cell 102. If the bottom surface of the upper battery cell 102 is adsorbed with the remaining battery cells 102 located in the lower layer, the position of the blowing port is just opposite to the position of the adsorption joint of the two battery cells 102, and the airflow generated by the blowing port can destroy the negative pressure state between the two battery cells 102, that is, the remaining battery cells 102 adsorbed on the picked-up battery cell 102 can be separated, so that the remaining battery cells 102 fall back into the tray 101.

[0042] The transport robot provided in the present application is provided with a blowing mechanism 104 to separate the remaining battery cells 102 adsorbed on the picked battery cell 102, thereby avoiding the problem of missing the battery cells 102 in the testing process due to the joint phenomenon when picking up the battery cells 102, and avoiding the problem of defective or even scrapped products due to the adsorbed battery cells 102 falling when the transport robot moves.

[0043] In an optional solution of this embodiment, the picking mechanism 103 includes a mounting frame and a plurality of picking components 106; the plurality of picking components 106 are mounted on the mounting frame, and the plurality of picking components 106 are spaced apart to pick up a plurality of battery cells 102; a blowing mechanism 104 is disposed between adjacent picking components 106, and the blowing mechanism 104 is mounted on the mounting frame.

[0044] In this embodiment, if Figure 2 As shown, the transport robot includes two picking mechanisms 103 and a connecting frame 105. Both picking mechanisms 103 are mounted on the connecting frame 105, and the connecting frame 105 is connected to the free end of the robot arm. Each picking mechanism 103 includes a mounting frame and three picking components 106 connected to the mounting frame. The three picking components 106 are arranged at intervals and are opposite to the carrying slots 107 arranged at intervals in the tray 101. Each picking component 106 can pick up the battery cell 102 in the corresponding carrying slot 107. The tray 101 shown in the figure is provided with a plurality of carrying slots 107 arranged in three rows and six columns. During one transport process of the transport robot, the transport robot can simultaneously pick up six battery cells 102 in a row of carrying slots 107 in the tray 101 to the loading position, which greatly improves the transport efficiency.

[0045] In addition, the blowing mechanism 104 is also installed on the mounting frame, and the blowing mechanism 104 is located at the gap between the picking components 106, which reasonably utilizes the gap between the picking components 106, does not increase the overall size of the picking mechanism 103, and the structure of the device is more compact.

[0046] In an optional scheme of this embodiment, the blowing mechanism 104 includes a first driving device 108 and a blowing assembly 109. The first driving device 108 is used to drive the blowing assembly 109 to extend and retract along a preset direction so that the blowing assembly 109 moves to a blowing position or an avoidance position; the preset direction is the direction in which the picking mechanism 103 picks up the battery cell 102.

[0047] In this embodiment, if Figure 1 As shown, a plurality of bearing slots 107 are provided in the tray 101, and the slots of the bearing slots 107 face upwards, the battery cells 102 are placed flat in the bearing slots 107, and the direction in which the picking mechanism 103 picks up the battery cells 102 is in the vertical direction. A partition structure is provided between adjacent bearing slots 107, and before the picking mechanism 103 extends into the bearing slots 107 to pick up the battery cells 102, the first driving device 108 drives the blowing assembly 109 to rise to the avoidance position to avoid interference between the blowing assembly 109 and the partition structure.

[0048] To ensure that the battery cell 102 picked up by the picking mechanism 103 does not adsorb the remaining battery cells 102, the air blowing assembly 109 needs to blow air on the battery cell 102 twice. Specifically, when the picking mechanism 103 lifts the battery cell 102 to the first height, the first driving device 108 drives the air blowing assembly 109 to descend to the air blowing position to perform the first air blowing separation on the battery cell 102. At the same time, the robotic arm shakes the battery cell to accelerate the dropping of the adsorbed battery cells. After the end of the first air blowing process, the picking mechanism 103 lifts the battery cell 102 to the second height, and the air blowing assembly 109 can blow air on the battery cell 102 again for the second air blowing separation to ensure that the adsorbed battery cell 102 falls back to the tray 101. Finally, since the battery cell 102 at the second height is located outside the tray, the robotic arm can translate the battery cell 102 at the second height to avoid the tray, and the robotic arm can move the battery cell 102 to the test station.

[0049] In an optional solution of this embodiment, specifically, the air blowing assembly 109 includes a first bracket 110 and an air blowing pipe 111. The air blowing pipe 111 is provided with an air blowing port facing the battery cell 102, and the air blowing pipe 111 is installed on the first bracket 110. The air blowing pipe 111 is connected to an air blowing device, and the air blowing device can output a corresponding air blowing time according to the stacking layer number of the battery cell 102 on the tray 101. The first driving device 108 is specifically a cylinder, and the driving end of the first driving device 108 is connected to the first bracket 110 to drive the air blowing pipe 111 to lift and lower, so as to avoid the partition structure of the tray 101.

[0050] During actual operation, after the picking mechanism 103 picks up the battery cell 102 and lifts the battery cell 102 to a certain height, the first driving device 108 drives the air blowing assembly 109 to descend to the air blowing position to blow air on the battery cell 102. At this time, the air blowing device starts timing. After the timing ends, the first driving device 108 drives the air blowing assembly 109 to rise to the avoidance position, thus ending the air blowing action. Since the battery cells 102 are stacked and placed in the tray 101, due to the action of gravity, the adsorption force between the lower battery cells 102 is greater, and the corresponding air blowing time needs to be longer to separate the battery cells 102.

[0051] According to the above principle, in the program of the air blowing device, the battery cells 102 (from top to bottom) in each carrying slot 107 in the tray 101 are defined as layers 0 - 18. The first layer of battery cells 102 is layer 0, and the lowest layer of battery cells 102 is layer 18. Each time the picking mechanism 103 picks up a battery cell, the number of picked trays +1. As Figure 4As shown in the figure, the air blowing time for each layer of battery cells 102 is the sum of the first air blowing time (the air blowing time at the jitter position in the figure) and the second air blowing time (the air blowing time at the avoidance position in the figure). In the ladder diagram of step 37 in the program, for the battery cells 102 in layers 0 - 5, the air blowing time is equal to the first air blowing time of 0.2 s plus the second air blowing time of 0.1 s. In the ladder diagram of step 38 in the program, for the battery cells 102 in layers 6 - 10, the air blowing time is equal to the first air blowing time of 0.4 s plus the second air blowing time of 0.1 s. In the ladder diagram of step 39 in the program, for the battery cells 102 in layers 1 - 18, the air blowing time is equal to the first air blowing time of 0.8 s plus the second air blowing time of 0.1 s.

[0052] In addition, as Figure 3 shown, the mounting bracket includes a mounting plate 112, and a plurality of picking components 106 are mounted on the lower plate surface of the mounting plate 112 along the length direction of the mounting plate 112, so as to correspond to the arrangement direction of the bearing grooves 107 in the tray 101, thereby achieving precise picking of the battery cells 102 in a plurality of bearing grooves 107. The first driving device 108 is mounted on the upper plate surface of the mounting plate 112, and the first bracket 110 extends to the side of the lower plate surface of the mounting plate 112, so that the setting of the first driving device 108 will not interfere with the battery cells 102 and the tray 101, and can achieve the purpose of separating the battery cells 102.

[0053] In an optional solution of this embodiment, referring to Figure 3 shown, the first bracket 110 includes a transverse plate and two vertical plates arranged at intervals. The driving end of the first driving device 108 is connected to the middle of the top surface of the transverse plate. The blowing pipes 111 are installed on both vertical plates, and both vertical plates are connected to both ends in the length direction of the transverse plate, and the two vertical plates are respectively located on both sides in the width direction of the mounting plate 112, so that the blowing pipes 111 are arranged at intervals on the side of the battery cells 102, and the blowing pipes 111 blow air on the battery cells 102 together, thereby achieving a better separation effect.

[0054] Preferably, the air blowing assembly 109 further includes a mounting block 113 for fixing the blowing pipes 111. Specifically, the mounting block 113 and the first bracket 110 enclose to form a mounting hole, and the blowing pipes 111 are installed in the mounting hole, which can achieve the fixation of the blowing pipes 111. The mounting block 113 and the first bracket 110 are correspondingly provided with connection holes, so that the mounting block 113 and the first bracket 110 can be connected by bolts. The length direction of the mounting hole is the vertical direction, and the blowing pipes 111 installed in the mounting hole are also vertically placed. If it is necessary to adjust the position of the air blowing port of the blowing pipes 111, the bolts connecting the mounting block 113 and the first bracket 110 can be loosened, and the position of the air blowing port can be adjusted.

[0055] In an alternative solution of this embodiment, the air blowing mechanism 104 further includes a second bracket 114. The first driving device 108 is installed on the second bracket 114, and the second bracket 114 is connected to the mounting plate 112. Specifically, the second bracket 114 includes a horizontal plate and a vertical plate. The horizontal plate and the vertical plate are connected to form an L-shaped structure. The horizontal plate is connected to the mounting plate 112, and the first driving device 108 is installed on the vertical plate, thereby realizing the fixation of the first driving device 108.

[0057] The carrying manipulator in this Embodiment Two is an improvement based on the above embodiment. The technical content disclosed in the above embodiment will not be described repeatedly, and the content disclosed in the above embodiment also belongs to the content disclosed in this Embodiment Two.

[0058] Refer to Figure 3 As shown, in an alternative solution of this embodiment, the picking component 106 includes a fixing plate 115 and a plurality of suction cups 116. Since the two air blowing pipes 111 are respectively located on both sides in the width direction of the mounting plate 112, the width of the mounting plate 112 is relatively narrow to avoid too large a spanning distance between the air blowing pipes 111 on both sides. The fixing plate 115 is connected to the mounting plate 112, and a plurality of suction cups 116 are installed on the fixing plate 115. The fixing plate 115 can provide a larger installation range for the plurality of suction cups 116. Specifically, the fixing plate 115 is provided with a plurality of fixing holes 117 arranged at intervals to fix the plurality of suction cups 116. The plurality of suction cups 116 are arranged at intervals to form a larger adsorption area, and the adsorption effect on the battery cell 102 is more stable, which can avoid the dropped battery cell 102 being picked up.

[0059] Preferably, the fixing holes 117 are waist-shaped holes. When installing the suction cups 116 in the fixing holes 117, the installation positions of the suction cups 116 can be adjusted as needed to realize the picking of battery cells 102 of multiple sizes.

[0060] In an alternative solution of this embodiment, the picking mechanism 103 further includes a second driving device 118. The second driving device 118 is specifically a cylinder, and the second driving device 118 is connected to the mounting frame to drive the plurality of picking components 106 to move up and down synchronously, so as to pick up the battery cell 102 in the tray 101 and place the battery cell 102 at the test station.
