[0002] Battery assembly is an important step in the battery manufacturing process. The cluster group is formed by encapsulating the positive plate, negative plate, and separator. The cluster group will be assembled into the battery slot after cast welding. The thickness of the cluster group will directly affect the next process of the battery - cast welding into the slot. In order to confirm whether the cluster group after encapsulation can meet the slot requirements, it is necessary to measure the thickness of the cluster group and compare it with the single grid spacing of the slot for confirmation. After the cluster group is assembled, the assembly pressure of the plate has a certain impact on the thickness of the cluster, resulting in different personnel and different measurement positions when using a caliper to measure the cluster thickness, and the measurement data is quite different; the existing cluster thickness detection device needs to stop and wait for the test results during the cluster thickness measurement process, which does not meet the online automatic test, resulting in multiple shutdowns and detections caused by the inability of the battery to enter the slot during the production process, affecting production efficiency and product quality.

DETAILED DESCRIPTION

[0020] like Figure 1As shown, the cluster thickness detection device includes a fixed plate 1, a force sensor 3, a base 4, a slide rail 5, a servo motor 6, a servo motor fixed seat 7, a pole group detection platform 8, a lead screw 9, a controller 10, and a signal line 11. The pole group detection platform 8 is vertically fixed on one side of the fixed plate 1, the force sensor 3 is mounted on the base 4, and the detection surface of the force sensor 3 is parallel to the fixed plate 1; the bottom of the base 4 has a slide groove that matches the slide rail 5, the base 4 can move on the slide rail 5, the slide rail 5 is fixed on the bottom plate, the middle of the base 4 has a mounting hole, and the mounting hole has a tooth pin that matches the outer spiral groove of the lead screw 9, the middle of the lead screw 9 passes through the mounting hole, one end is mounted in the lead screw seat, and the other end is connected to the output shaft of the servo motor 6, the servo motor 6 is mounted on the servo motor fixed seat 7, and the servo motor fixed seat 7 is fixed on the bottom plate, and the controller 10 is connected to the force sensor 3 and the servo motor 6 via the signal line 11.

[0021] like Figure 2 As shown, the thickness detection module is located between the pole group to be detected conveyor line 13 and the pole group after detection conveyor line 15, and the robot 12 is used to grab the pole group to be detected from the pole group to be detected conveyor line 13 to the thickness detection module and to transfer the pole group after detection from the thickness detection module to the pole group after detection conveyor line 15.

[0022] In another embodiment, a defective product ejection device is provided on the pole group conveyor line 15, and the defective product ejection device includes a push plate, a defective product placement table 16, and an ejection cylinder 14 for driving the push plate; the push plate and the defective product placement table 16 are respectively arranged on both sides of the pole group conveyor line 15 after inspection. The ejection cylinder 14 is connected to the controller 10 via a signal line. The controller 10 can be a PLC controller. It is a prior art that the controller 10 collects signals from the force sensor 3 and the servo motor 6, and then controls the manipulator 12 and the ejection cylinder 14 to move. This embodiment will not be repeated in detail.

[0023] When measuring the thickness of cluster 2, the controller 10 transmits the control signal to the servo motor 6 through the signal line 11, and the servo motor 6 drives the lead screw 9 to rotate. The rotation of the lead screw 9 drives the base 4 to move toward the cluster 2 on the slide rail 5, so that the force sensor 3 contacts the outer surface of the cluster 2. The force sensor 3 stops moving after applying the specified pressure value, and the servo motor 6 sends the number of rotations back to the controller 10, which determines whether the thickness of the pole group meets the requirements (when debugging the thickness detection device, the distance between the initial position of the base 4 and the fixed plate 1 is set to a fixed value, and the pole group thickness value that meets the requirements is also a known value. The distance between the initial position of the base 4 and the fixed plate 1 minus the distance that meets the requirements The pole group thickness value is the distance that the base 4 needs to move during the test. The distance that the base 4 needs to move can be converted into the required number of rotations of the servo motor 6. The required number of rotations is set as a judgment value in advance in the controller. If the actual number of rotations of the servo motor 6 during the test is greater than or less than the set required number of rotations, it is judged to be unqualified. This part of the content is the prior art and will not be described in detail in this embodiment). Then the pole group is grabbed to the post-inspection pole group conveyor line 15. If it does not meet the requirements, the controller controls the ejection cylinder 14 and the push plate of the unqualified product ejection device to push the unqualified product to the unqualified product placement table 16. The symbol requires the pole group conveyor line 15 to run to the next production process after inspection.
