[0065] In the description of the present invention, it is necessary to understand that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0066] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] The overall concept of the present invention is as follows:

[0068] (1) The detection device 4 detects whether the adhesive bonding of the battery cell 100 is qualified, which is fully automated, without missed detection or wrong detection, and the detection is more accurate, without manual participation, and has high efficiency.

[0069] (2) The clamping device 3 is used to clamp the NG battery cells 100 off the line or the qualified battery cells 100 for caching, which is also fully automated, does not require manual intervention, is highly efficient, and eliminates safety hazards.

[0070] See also Figures 1 to 12 shown.

[0071] A mechanism for automatically detecting qualified glue sticking of battery cells, comprising:

[0072] Support frame 1;

[0073] The XYZ three-axis moving device 2 is fixed on the supporting frame; the XYZ three-axis moving device 2 can adopt the existing three-axis gantry, which is a standard part, and can realize the adjustment of the X\Y\Z three-axis coordinates, thereby adjusting the three-axis coordinates of the clamping device 3 and the detection device 4, which is convenient for detection, clamping and transportation.

[0074] The clamping device 3 is fixed to the Z-axis output end 21 of the XYZ three-axis moving device 2; the clamping device 3 is used to clamp the NG battery cell 100 and place it on the conveyor line 6 for offline, or clamp the qualified battery cell 100 and place it in the buffer device 5 for buffering. It should be explained that the buffer device 5 is suitable for the situation where every two battery cells are clamped by a module tray. In a specific actual production, the setting of the production line requires that both battery cells are qualified before they can flow to the next process, otherwise it will cause the rhythm of the downstream process to be disrupted. The module tray is transported by the conveying device to the bottom of the clamping device 3 and the detection device 4 for glue sticking qualified detection. Therefore, if one battery cell on a module tray has qualified glue application and the other battery cell is NG, the NG battery cell needs to be clamped and placed on the conveyor line 6, and the qualified battery cell needs to be clamped and placed in the cache device 5 for storage first, waiting for the next module tray to have a qualified and a NG battery cell. At this time, after the NG battery cell is clamped and placed on the conveyor line 6, the qualified battery cell stored in the cache device 5 is clamped and placed on the module tray, and the two qualified battery cells are collected and then transferred to the next process to avoid disrupting the downstream production process.

[0075] The detection device 4 is fixed to the Z-axis output end 21 of the clamping device 3 or the XYZ three-axis moving device 2, and is used to detect whether the battery cell adhesive is qualified. In a specific embodiment, the detection device 4 is fixed to the clamping device 3, and it is only necessary to ensure that the two do not interfere with each other.

[0076] The buffer device 5 is fixed to the top surface of the support frame 1 and is located below the XYZ three-axis moving device 2; it is used for the situation where there is one qualified cell and one NG cell on a module tray, and the qualified cells are stored on the buffer device 5;

[0077] The conveyor line 6 is fixed on the support frame 1 and is located below the XYZ three-axis moving device 2, and the end of the conveyor line 6 extends out of the XYZ three-axis moving device 2. The conveyor line 6 outputs the NG battery cell from the bottom of the XYZ three-axis moving device 2 to the outside. The purpose of setting the conveyor line 6 is that, in a specific implementation, for the purpose of safe production, a safety protection cover (not shown) will be provided on the outer ring of the XYZ three-axis moving device 2, and the conveyor line 6 passes through the safety protection cover (not shown) to transport the NG battery cell to the outside of the safety protection cover (not shown), so as to avoid potential safety hazards caused by workers directly entering the safety protection cover (not shown) to take out the NG battery cell during production.

[0078] The clamping device 3 comprises:

[0079] A fixed frame 31, fixedly connected to the Z-axis output end 21 of the XYZ three-axis moving device 2; for example, it can be fixedly connected to the Z-axis output end 21 of the XYZ three-axis moving device 2 through a transfer tube 311;

[0080] The rotating frame 32 is rotatably connected to the fixed frame 31; in a specific implementation, the rotating frame 32 can be connected to the fixed frame 31 in a hinged manner to achieve rotation. Of course, the rotation can also be achieved in other ways, such as a rotating shaft is provided on both sides of the rotating frame 32 and the fixed frame 31 to achieve rotation. In order to make the rotation smoother, a pair of bearings can be sleeved on the rotating shaft, wherein the outer ring of one bearing is nested on the rotating frame 32, and the outer ring of the other bearing is nested on the fixed frame 31. Alternatively, the embodiment shown in the accompanying drawings is adopted, and a hinge shaft 321 is respectively provided on both sides of the rotating frame 32, and the hinge shaft 321 passes through the fixed frame 31, and then a connecting plate 322 is fixed at the end of the hinge shaft 321 on the same side of the rotating drive device 33, and the connecting plate 322 is hinged to the output end of the rotating drive device 33; the piston rod of the rotating drive device 33 is extended and retracted, and the connecting plate 322 is pulled, thereby driving the hinge shaft 321 to rotate, and finally driving the rotating frame 32 to rotate.

[0081] The rotary drive device 33 is fixed to the fixed frame 31, and the output end is connected to the rotating frame 32; the function of the rotary drive device 33 is to adjust the posture of the battery cell. For example: whether it is placed upright, the end with a smaller area faces downward, which is unstable and easy to tip over and damage the battery cell; or placed horizontally, the side with a larger area faces downward, which is more stable. Usually the battery cell is a rectangular parallelepiped, and the incoming material direction is that the battery cell is clamped by a module tray, so it does not matter whether it is placed upright or horizontally. However, when an NG battery cell is detected, the clamping device 3 clamps the NG battery cell and places it on the conveyor line 6. The battery cell needs to be rotated to adjust its posture so that it is placed horizontally on the conveyor line 6 to avoid tipping over. In a specific implementation, the rotary drive device 3 can use an actuator, such as a cylinder or a hydraulic cylinder.

[0082] There is at least one clamping jaw driving device 34, which is fixed to the rotating frame 32; the clamping jaw driving device 34 can be a clamping jaw cylinder, a pneumatic finger or a pneumatic clamping jaw.

[0083] There are at least two clamping jaws 35 , and each two clamping jaws 35 are symmetrically and fixedly connected to an output end of the clamping jaw driving device 34 to achieve synchronous opening and closing movements.

[0084] The clamping device 3 also includes:

[0085] The in-place detection device 36 is fixed to the clamping jaw driving device 34 and is used to detect whether the battery cell is between the two clamping jaws 35; to ensure that when an accident occurs and the battery cell falls off, the in-place detection device 36 cannot sense the battery cell 100, and can be promptly found and fed back to the control system, so as to facilitate timely alarm prompts. In a specific implementation, the in-place detection device 36 can adopt detection devices such as distance sensors, photoelectric sensors or proximity switches. The in-place detection device 36 is used in combination with the first clamping detection device 37. Only when the first clamping detection device 37 detects that the clamping jaws 35 are clamped in place, the in-place detection device 36 cannot detect the battery cell 100, indicating that the battery cell 100 has fallen off. At this time, the control system is fed back to issue an alarm prompt, and at the same time, a false alarm is avoided when the battery cell 100 is not clamped.

[0086] The first clamping detection device 37 is fixed to one of the clamping jaws 35, and is used to detect whether the two clamping jaws 35 are clamped in place, which can play a role in preventing mistakes or foolishness. Under normal circumstances, if the clamping jaw driving device 34 adopts a cylinder, it has its own travel switch. After the travel is set, the corresponding travel switch senses that it is clamped. However, accidents may occur in the actual production process, resulting in the travel switch sensing, but there is actually no clamping. In the specific implementation, the first clamping detection device 37 can adopt a proximity switch.

[0087] The clamping device 3 also includes:

[0088] The first stopper 38 is horizontally fixed to the fixed frame 31; when the rotating frame 32 rotates and drives the two clamping jaws 35 to rotate to face vertically downward, the first stopper 38 abuts against one side of the rotating frame 32;

[0089] The second position-limiting member 39 is vertically fixed to the fixed frame 31 . When the rotating frame 32 rotates and drives the two clamping jaws 35 to rotate to a horizontal state, the second position-limiting member 39 supports the rotating frame 32 at the bottom.

[0090] The first limiting member 38 and the second limiting member 39 play a role of mechanical limiting to prevent the rotating frame 32 from being inaccurately positioned or out of control due to inertia, power failure, gas failure, etc. In a specific implementation, hydraulic buffers, bolts, and other components can be used.

[0091] The detection device 4 comprises:

[0092] The mounting bracket 41 is fixed to the Z-axis output end 21 of the clamping device 3 or the XYZ three-axis moving device 2; as in a specific embodiment, the mounting bracket 41 is fixed to the fixing frame 31 and is staggered to leave space for taking pictures.

[0093] The light source 42 is fixed to the mounting bracket 41 and is used to provide lighting and increase brightness.

[0094] The number of visual cameras 43 and the clamping drive device 34 is equal, that is, they take pictures of the battery cells one by one, and are fixed to the mounting bracket 41 respectively, and arranged downward, for taking pictures of the battery cells, detecting whether the battery cell glue is qualified, and at the same time, the placement of the battery cells can be detected, such as: whether it is placed upright, in which case the end with a small area faces downward, the placement is unstable, and it is easy to tip over and damage the battery cell; or placed horizontally, in which case the side with a large area faces downward, and the placement is more stable. Usually, the battery cell is a rectangular parallelepiped, and the incoming material direction is that the battery cell is clamped by a module tray, so it does not matter whether it is placed upright or horizontally. However, when an NG battery cell is detected, when the clamping device 3 clamps the NG battery cell and places it on the conveyor line 6, the battery cell needs to be rotated to adjust its posture so that it is placed horizontally on the conveyor line 6 to avoid tipping. Therefore, the visual camera 43 can take pictures of the area of ​​the battery cell to see whether it is placed horizontally or upright, so as to determine whether the posture of the battery cell needs to be adjusted.

[0095] The cache device 5 comprises:

[0096] The clamping drive device 51 is fixed to the support frame 1; it can also adopt a clamping cylinder, pneumatic fingers or pneumatic clamping jaws.

[0097] There are two clamping plates 52, which are symmetrically fixed to the output end of the clamping drive device 51 to achieve synchronous opening and closing movement;

[0098] The buffer support plate 53 is disposed between the two clamping plates 52. In the embodiment shown in the figure, the buffer support plate 53 is directly fixed on the cylinder body of the clamping drive device 51.

[0099] The cache device 5 also includes:

[0100] The second clamping detection device 54 is fixed to one of the clamping plates 52 and is used to detect whether the two clamping plates 52 are clamped in place. The second clamping detection device 54 can also be a proximity switch.

[0101] A baffle 61 is also provided at the end of the conveyor line 6 to block the NG battery cells and prevent them from falling;

[0102] A row of guide wheels 62 are respectively provided on both sides of the conveyor line 6 for guiding the battery cells.

[0103] The conveyor line 6 is also provided with a vacancy detection device 63 before the entrance of the guide wheel 62;

[0104] The empty position detection device 63 is used to detect whether there are battery cells at the entrance of the guide wheel 62 to prevent battery cells from colliding with each other or being stacked and tipping over and being damaged during transportation.

[0105] The conveyor line 6 is also provided with a material-removing reminder detection device 64 in front of the baffle 61;

[0106] The reminder material removal detection device 64 is used to detect whether a predetermined number of battery cells are stored on the conveyor line 6. It is convenient for the staff to come and take away the NG battery cells, so as to avoid the conveyor line 6 being full and unable to store the NG battery cells, and to avoid the inspection and waiting. If the length of the conveyor line 6 is assumed to be able to store 8 NG battery cells, in order to ensure production continuity, the reminder material removal detection device 64 can be arranged at the length position where three NG battery cells are stored, so that the staff can take away the NG battery cells in time and empty the conveyor line 6.

[0107] In a specific implementation, both the material-taking reminder detection device 64 and the empty position detection device 63 can adopt photoelectric counter-radiation sensors.

[0108] In a specific implementation, a photoelectric corresponding sensor 65 may be added between the material-taking reminder detection device 64 and the empty position detection device 63 to detect whether the battery cell is skewed or stuck during the conveying process.

[0109] Specific usage:

[0110] There are two gripper driving devices 34 corresponding to the gripping of two battery cells.

[0111] The conveying line 6 can be a belt line.

[0112] The XYZ three-axis moving device 2, conveyor line 6, rotation drive device 33, clamping jaw drive device 34, in-position detection device 36, first clamping detection device 37, light source 42, visual camera 43, clamping drive device 51, second clamping detection device 54, empty position detection device 63, material picking reminder detection device 64, photoelectric beam sensor 65 and other electrical components are respectively communicatively connected to the control system of the production line, such as PLC.

[0113] The support frame 1 is set up on the production line, such as next to the double-speed chain, and the clamping device 3 and the detection device 4 are located above the double-speed chain. Each module tray clamps two battery cells, which are transported by the double-speed chain to the bottom of the clamping device 3 and the detection device 4 for detection.

[0114] The working procedure is preset in the PLC. It can be pre-set that after the module tray is in place, the clamping device 3 is located directly above the battery cell, and the clamping battery cell can be directly lowered. Since the clamping device 3 and the visual camera 43 do not interfere with each other, the visual camera 43 can also directly take pictures for detection.

[0115] The PLC controls the speed chain to transport the two battery cells on the module tray to the predetermined position below the clamping device 3 and the detection device 4. A position sensor can be preset on the production line or the module tray to detect the position, such as the module tray feeding back the position signal to the PLC.

[0116] The PLC controls the visual camera 43 to take pictures of the battery cells to detect whether the battery cell glue is qualified.

[0117] If the photo test results show that both cells are qualified, the PLC will notify the speed chain to release the two cells for transportation;

[0118] If the photo detection result shows an NG battery cell, the PLC controls the Z-axis output end 21 of the XYZ three-axis moving device 2 to descend to a predetermined position, and then controls the two clamping jaw driving devices 34 to drive their respective clamping jaws 35 to clamp a battery cell respectively;

[0119] The PLC compares the photographing result of the visual camera 43 with the preset conditions to determine whether the battery cell needs to be adjusted. If necessary, the PLC controls the rotation drive device 33 to rotate the two battery cells 90° for posture adjustment. Figure 6 and Figure 7 Corresponding to two postures of the battery cell 100 .

[0120] The PLC controls the XYZ three-axis moving device 2 to move, places the qualified battery cells on the buffer support plate 53, and then controls the clamping drive device 51 to drive the two clamping plates 52 to clamp the qualified battery cells in the buffer position; the PLC controls the XYZ three-axis moving device 2 to move, and places the NG battery cells on the conveyor line 6;

[0121] The PLC controls the conveyor line 6 to operate, so that the NG battery cells are conveyed to the outside of the XYZ three-axis moving device 2 and are blocked by the baffle 61 at the end of the conveyor line 6;

[0122] PLC controls the XYZ three-axis moving device 2 to return and continue to take pictures to detect the battery cells, and repeatedly detect and screen whether the battery cells are qualified;

[0123] If there is a qualified battery cell in the cache position, and a qualified battery cell and a NG battery cell appear in the photo detection, the PLC first controls one of the clamping jaw driving devices 34 to drive the corresponding two clamping jaws 35 to clamp the NG battery cell, and place it on the conveyor line 6 for offline; then controls the XYZ three-axis moving device 2 to move, so that one of the clamping jaw driving devices 34 clamps the qualified battery cell 100 in the cache position and places it on the module tray, forming two qualified battery cells 100, and then controls the double-speed chain to release, so that the two qualified battery cells enter the next process together with the tray.

[0124] Among them, when the conveyor line 6 conveys the NG battery cell to the end, it will first pass through the reminder material collection detection device 64. In order to avoid the situation where the reminder material collection detection device 64 detects the passing NG battery cell, but the stored quantity has not reached the predetermined quantity, thereby causing a false alarm, it can be preset that when the NG battery cell is placed on the conveyor line 6 and the conveyor line 6 starts working, the PLC first controls the reminder material collection detection device 64 to stop working for a certain period of time. For example, it can be preset according to the time when the battery cell is conveyed to the very end, so that the battery cell passes first, and then the reminder material collection detection device 64 is controlled to start working after the time is up. At this time, if the reminder material collection detection device 64 senses the battery cell 100, it indicates that the conveyor line 6 has stored the predetermined quantity of NG battery cells. The PLC can control the alarm device of the production line to issue an alarm prompt, and the staff will come to remove the NG battery cell located outside the XYZ three-axis moving device 2 of the conveyor line 6.

[0125] When placing NG battery cells on the conveyor line 6, the vacancy detection device 63 must detect no battery cells at the entrance before putting them down. Otherwise, the alarm device of the PLC-controlled production line will sound an alarm and stop the detection, waiting for staff to come and handle the abnormality.
