Description

Technical Field

[0001] The present application relates to the technical field of battery production, and in particular to a connecting piece feeding detection device and a connecting piece feeding system. Background Art

[0002] At present, connecting pieces are commonly used to connect the tab bundle and the cover plate in the production process of square aluminum shell batteries. After the battery cell is put into the shell, the tab bundle is in a horizontal plane, and the cover plate needs to be welded to the shell in a vertical plane. Therefore, the connecting piece is ultrasonically welded to the tab bundle and laser welded to the cover plate in the horizontal plane, and then the connecting piece is bent to change the cover plate from a horizontal plane to a vertical plane for shell cover welding.

[0003] On this basis, a bending groove is set for the connecting piece to guide the bending and improve the stress to avoid the risk of internal short circuit caused by reverse insertion after bending. If the bending position is not at the bending groove, the bending will be unguided and the stress will be large, which is very likely to cause reverse insertion. Therefore, during the feeding process of the connecting piece, it is necessary to pay attention to its posture. The connecting piece needs to be placed horizontally and its bending groove is set downward, so the detection of the feeding posture is particularly important. However, the current common detection method is manual confirmation after feeding. This process relies on the responsibility of the personnel and is prone to failure, or CCD (Charged Coupled Device, also known as image sensor) is used for photo detection, and the equipment cost is relatively high.

[0043] Refer to the following Figures 1 to 9 The invention describes a connecting piece feeding detection device and a connecting piece feeding system according to some embodiments of the present application.

[0044] Embodiment 1

[0045] See also Figures 1 to 6As shown, an embodiment of the present application provides a connecting piece feeding detection device 10, which is used to detect the feeding posture of a connecting piece 50, and the connecting piece 50 is formed with a bending groove 501. The connecting piece feeding detection device 10 comprises: a positioning platform 1 and at least one probe detection assembly 2; wherein the positioning platform 1 is formed with a positioning groove 111, which is used to place the matching connecting piece 50; any probe detection assembly 2 comprises a plurality of sensing probes 23, and the plurality of sensing probes 23 are sequentially arranged along a first direction a, and the sensing end of any sensing probe 23 extends into the positioning groove 111 via the bottom of the positioning groove 111;

[0046] When a single connecting piece 50 is placed in the positioning groove 111 in a preset correct posture, one of the probe detection components 2 is located directly below the bending groove 501 .

[0047] According to the structure described above, the process of detecting the connecting piece 50 using the connecting piece feeding detection device 10 provided by the present application is as follows (and preferably, a bending groove 501 is formed on the connecting piece 50, and the connecting piece 50 only needs to be bent once):

[0048] When the robot mechanism 20 transports the connecting piece 50 to the positioning groove 111 of the positioning platform 1, the sensing end of the highest point of the detection probe in the probe detection assembly 2 detects the bending groove 501 on the connecting piece 50. If a group of probes detects that the bending groove 501 is in the correct position, it means that the front and back sides of the connecting piece 50 are correct, that is, they are not placed wrong.

[0049] It can be seen that the connecting piece feeding detection device 10 provided in the present application can detect whether the feeding posture of the connecting piece 50 is correct or not, thereby avoiding feeding posture errors, which may cause the connecting piece 50 to bend without guidance, increase stress and cause the risk of inverted insertion, thereby improving production efficiency, being less prone to errors and having lower costs.

[0050] Further, preferably, Figure 2 , Figures 4 to 6 As shown, the number of the probe detection components 2 is two, and the two probe detection components 2 are sequentially arranged along the second direction b that forms an angle with the first direction a. The advantage of designing two groups of probes here is that in order to avoid the tilting of the multiple stacked connecting pieces 50 (such as Fig. 9 As shown), the plurality of connecting pieces 50 are connected in the following manner: Figure 8 If the connecting piece 50 is stacked in the manner shown, the position of the bending groove 501 is different in the two different placement states, specifically, in the first state, the bending groove 501 is located on the right, and in the second state, the bending groove 501 is located on the left. Therefore, it is necessary to design two sets of probes to effectively detect the bending groove 501 of the connecting piece 50 in different states.

[0051] In addition, taking the case where the bending groove 501 is on the right side as an example, a group of probes on the left side can also detect the connecting piece 50 structure on the left side of the bending groove 501 to detect whether it is warped or deformed, thereby further improving the detection accuracy. Similarly, when the bending groove 501 is on the left side, a group of probes on the right side can also detect the connecting piece 50 structure on the right side of the bending groove 501.

[0052] Further, preferably, Figure 2 and Figure 4 As shown, the second direction b is perpendicular to the first direction a, that is, all the sensing probes 23 in the two probe detection components 2 are arranged in a square array. Of course, it is not limited to this, and can also be arranged in a parallelogram array, or in a trapezoidal array, etc., depending on actual needs.

[0053] Further, preferably, Figure 2 and Figure 4 As shown, any probe detection assembly 2 includes two sensing probes 23. Of course, this is not limited to this. The number of sensing probes 23 can be more than two, for example, three sensing probes 23, four sensing probes 23 or five sensing probes 23, etc., which can be selected according to actual needs.

[0054] Of course, the number of the probe detection components 2 is not limited to two, but can also be one. In this case, before detection, all the connecting sheets 50 are stacked in the same posture in the feeding mechanism 30 or in other spaces.

[0055] In combination with the above structure, the above two probe detection components 2 are used, and each probe detection component 2 includes two probes, that is, a total of four probes, and the first state, that is, the connecting piece 50 in which the bending groove 501 is located on the right is detected, and a signal combination judgment can be made: each group of probes is divided into a first probe and a second probe. There are 8 signal combinations in the actual process, and the judgment definitions are given as shown in the above table:

[0056] a. Receive signals from two probes in group A 21 at the same time and judge them as qualified;

[0057] b. Receive two probe signals from group A 21 and any one probe signal from group B 22 at the same time and judge as qualified;

[0058] c. Receive signals from two probes in group B 22 at the same time and judge them as unqualified;

[0059] d. Receive two probe signals from group B 22 and any one probe signal from group A 21 at the same time and judge it as unqualified;

[0060] e. Probe group A 21 and group B 22 do not receive any probe signal at the same time, and are judged as unqualified (indicating that the front and back sides of the connecting piece 50 are wrong or the depth of the bending groove 501 is not enough);

[0061] f. Probe group A 21 and group B 22 receive all probe signals simultaneously and determine that the signal is unqualified (indicating that the connecting piece 50 is severely deformed).

[0062] Similarly, for the signal combination determination for the second state, that is, the bending groove 501 is located on the right connecting piece 50, refer to the above, but the A group 21 and the B group 22 need to be swapped.

[0063] Of course, this is just an example, and the specific signal combination determination can be selected according to actual needs.

[0097] A plurality of connecting sheets 50 are stacked in sequence from bottom to top in the loading mechanism 30, and the loading mechanism 30 pushes the plurality of connecting sheets 50 upward so that the top connecting sheet 50 is in the loading position.
