[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a battery loading error prevention mechanism includes a base 1 and a detection assembly 2 thereon, wherein the base 1 is provided with an anti-mistake component 11 for use with a battery loading tray, and the detection assembly 2 includes an electrically connected micro switch 21 and an audible and visual prompt device 22; the battery loading tray pushed into the base 1 triggers the micro switch 21 and causes the audible and visual prompt device 22 to make corresponding changes and prompts, and the audible and visual prompt device 22 used in this embodiment is a three-color switching indicator light with a buzzer.

[0030] like Figure 2-3As shown, the base 1 includes a bottom plate 12 and side plates 13 and a baffle 14 arranged around the bottom plate 12. The side plates 13 and the baffle 14 form an enclosed tray accommodating cavity 15 on the bottom plate 12, and the fool-proof component 11 is arranged in the tray accommodating cavity 15; the tray is placed flat on the bottom plate 12 and is pushed into the tray accommodating cavity 15 under the enclosure of the side plates 13 and the baffle 14. The fool-proof component 11 can be fully fitted into the corresponding fool-proof groove in the tray only when it corresponds to the corresponding fool-proof groove in the tray, thereby ensuring that the tray can be placed into the base 1 in the correct direction and the subsequent operations can be completed smoothly.

[0031] The micro switch 21 includes a switch body 211 and a contact 212 electrically connected to the switch body 211. The switch body 211 is arranged on the baffle 14, the contact 212 extends into the tray accommodating cavity 15, and the sound and light prompt device 22 is arranged on the base 1. When the tray is pushed into the tray accommodating cavity 15, the tray abuts against the baffle 14 and presses the contact 212. According to the triggering condition of the contact 212, the micro switch 21 is activated to control the sound and light prompt device 22 to emit corresponding light changes and sound warnings. When the tray is fully fitted, it turns to a green light, indicating that accurate code scanning and entry operations can be performed. When the tray is not pushed into place, it turns to a red light, and the buzzer in the indicator light sounds an alarm, prompting the staff to adjust the position of the tray. The working mode of the indicator light can be adjusted according to actual production needs. For example, when the tray has not been placed, the yellow light can be displayed as always, and when it is correctly placed, it turns to a green light, and when it is not placed in place, it turns to a red light and an alarm sounds.

[0032] Furthermore, the fool-proof component 11 is a block-shaped component protruding from the tray accommodating cavity 15, and its shape is triangular, cylindrical, rectangular or spherical. For example, the fool-proof component 11 provided in this embodiment is a right-angled triangular prism provided at the junction of the side plate 13 and the baffle 14 and protruding into the tray accommodating cavity 15. The two direct rectangular faces of the triangular prism are respectively fitted with the side plate 13 and the baffle 14, and the other oblique rectangular face faces the tray accommodating cavity 15. When the battery loading tray is pushed inward, the tray is also provided with a matching concave triangular prism groove at the corresponding position, and the micro switch 21 is smoothly triggered to issue a confirmation prompt. If the tray is placed in the wrong position, such as rotating 90° as a whole, it cannot be accurately placed in the tray accommodating cavity 15 after being pushed in. If the tray is blocked, the micro switch 21 cannot be triggered, and the sound and light prompt device 22 displays a reminder of incorrect placement, such as lighting up a red light or a yellow light and emitting a buzzer alarm. By setting the fool-proof component 11, the situation where the tray is placed incorrectly is effectively avoided.

[0033] Furthermore, a side plate 13 is provided on each of the left and right sides of the bottom plate 12, and a baffle 14 is provided at the end of the tray pushing direction and connected to the side plates 13 on the left and right sides. The side plate 13 is provided with an inclined surface 131 perpendicular to the bottom plate 12 on the side away from the baffle 14. The baffle 14 and the side plate 13 form a tray accommodating cavity 15 surrounded by three sides on the bottom plate 12, which limits the tray's entry direction and the barcode scanning direction of the tray. By providing the inclined surface 131 on the side plate 13 in the entry direction, the tray is easily pushed in.

[0034] Furthermore, the bottom plate 12 is provided with a transition step 121 at the front end of the tray pushing direction, and the transition step 121 is an inclined plane or an arc convex surface. In this embodiment, the transition step 121 is an arc convex surface, and when the tray is placed on the base 1, it can slide along the bottom plate 12 more smoothly.

[0035] Furthermore, a groove 141 is provided on the baffle 14, the micro switch 21 is provided in the groove 141, and the contact 212 protrudes from the groove 141 and extends into the tray accommodating cavity 15. The micro switch 21 is embedded in the groove 141, so that the switch body 211 is completely inserted, and the contact 212 thereon extends into the tray accommodating cavity 15. When the tray is pushed close to the baffle 14, it contacts the contact 212 and presses the contact 212, so that the sound and light prompt device 22 electrically connected to the micro switch 21 is controlled to send a signal.

[0036] Furthermore, the action stroke of the contact 212 is 1-5mm. The contact 212 of the micro switch 21 in this embodiment has a stroke of 3mm. When the distance between the forward push position of the tray and the baffle 14 is greater than 3mm, the contact 212 is not triggered, and the indicator light is a normal yellow warning. When there is a small gap of less than 3mm between the tray and the baffle 14, that is, the tray and the contact 212 are against but not attached to the baffle 14, the indicator light turns red and a buzzer alarm sounds, reminding the staff that the tray has not been placed in the correct position; and after the tray is pressed against the baffle 14, the buzzer alarm is lifted, and the warning red light also turns to a safe green light, that is, the tray is placed in the correct position, and the next step of scanning the battery cell can be performed, which can make subsequent operations more accurate.

[0037] like Figure 4-5 As shown, further, the base 1 is provided with a socket 16, and the sound and light prompt device 22 is inserted into the socket 16. In this embodiment, the socket 16 is provided at the junction of the baffle 14 and the side plate 13, the lower end of the sound and light prompt device 22 is inserted into the socket 16, and the upper end thereof protrudes upward perpendicularly to the bottom plate 12, so as to receive reminders more intuitively and simply. In more embodiments, the sound and light prompt device 22 and the socket 16 can be provided at any position of the base 1, as long as an obvious prompt effect can be achieved.

[0038] Furthermore, the base 1 is provided with a storage cavity 17 and a wire groove 18, and a power box 19 is provided in the storage cavity 17. The power box 19 is electrically connected to the micro switch 21 and the sound and light prompt device 22; the storage cavity 17, the groove 141 and the jack 16 are all connected through the wire groove 18. The micro switch 21 and the sound and light prompt device 22 are powered by the power box 19 in the storage cavity 17, and a battery can be inserted into the power box 19 or powered by an external power cord. The power box 19, the micro switch 21 and the sound and light prompt device 22 are all electrically connected by conducting wires, and the wires are laid in the wire groove 18, which can make the overall appearance of the base 1 more flat and convenient to use.

[0039] like Figure 2 As shown, further, it also includes an identification component 3, which includes a number of battery holes 31 and a label slot 32; a positioning label 33 is provided in the battery hole 31, and a tray information label 34 is provided in the label slot 32. The battery holes 31 correspond to the batteries to be processed loaded on the tray one by one. The battery holes 31 provided in this embodiment are a 16*16 array, with a total of 256 battery holes 31, and each battery hole 31 has a specific positioning label 33 corresponding to the battery position number in the tray. The positioning label 33 is a sticker with one side coated with glue and the other side with a digital number of 1-256, which is pasted in the battery hole 31 to achieve rapid positioning. The tray information label 34 in the label slot 32 is also a tray barcode identification sticker with adhesive. Through the above settings, the pallet MES barcode can be consistent with the physical barcode, and the recording position of the battery cell MES barcode and the actual position of the battery cell barcode on the pallet are consistent, and the consistency reaches 100%, achieving a significant and effective error prevention effect.

[0040] Further, the battery hole 31 is arranged on the side of the bottom plate 12 facing the tray accommodating cavity 15, the size of the battery hole 31 is a diameter range of 14-26mm and a depth of 1-5mm, and the size of the positioning label 33 is less than or equal to the size of the battery hole 31; the bottom plate 12 is also provided with auxiliary lines 35 that are evenly spaced and perpendicular to each other along the vertical and horizontal directions of the battery hole 31. The auxiliary lines 35 can be arranged at intervals of one auxiliary line 35 every 2, 4, or 8 battery holes 31, so as to quickly identify any of the battery holes 31. The size of the battery hole 31 arranged in this embodiment is 20mm in diameter and 1mm in depth, which can correspond to the 18650 battery cells loaded on the tray. The auxiliary lines 35 arranged on the bottom plate 12 are arranged at intervals of 4 battery holes 31 in the horizontal and vertical directions, respectively, that is, 256 battery holes 31 are divided into 16 areas, so that any battery hole 31 can be quickly found.

[0041] Through the guidance of identification component 3, the barcode of the loading pallet is ensured to be consistent with the information loaded in the MES system. The barcode information and placement positions of all battery cells in the pallet are also consistent with the system, so as to achieve accurate error prevention of battery loading and ensure that various test data in subsequent production are bound to the battery body, and the corresponding battery that needs to be processed can be quickly and accurately found based on this.

[0042] The specific working principle and use process of the battery loading error prevention mechanism are as follows:

[0043] The staff takes the tray loaded with the battery cells to be scanned, pushes the tray into the tray accommodating cavity 15 in the correct direction, and the triangular columnar anti-fool component 11 on the base 1 is embedded in the corresponding notch position of the tray. The tray is tightly against the baffle 14 and touches the contact 212 thereon for position detection. The sound and light prompt device 22 shows that the tray is in the correct direction and accurately positioned according to the detection results, and the indicator light turns green. After the staff receives the confirmation prompt, they log in to the MES system. Check whether the corresponding pallet information label 34 is pasted in the label slot 32, manually take the scanner to log in to the MES system with the barcode on the pallet information label 34 to bind the pallet, check the battery cell position number mark after binding, take the battery cell from the pallet and scan and enter the battery cell barcode on it, check whether the current position number mark is consistent with the position number displayed by the MES system by comparing the positioning label 33 in the battery hole 31, and scan all the battery cells in turn to complete the loading.

[0044] Through the above mechanical structure optimization and electrical status prompts, the accuracy of battery cell loading can be protected, which can effectively solve the error events caused by manually installing battery cells to MES position information. After using the battery device error prevention mechanism, the error rate is reduced to 0%. Correction is made from the behavior and habits of personnel, and guidance and prompts are given visually and auditorily. In the wrong state, the loading action cannot be completed, thus ensuring the accuracy of the loading data.

[0045] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
