Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a glue sticking mechanism for square batteries. Background Art

[0002] During the production process of square batteries, it is necessary to stick protective tape on the weld marks after ultrasonic welding of the tabs and laser welding of the adapters to ensure that metal debris that may be generated by welding does not enter the interior or surface of the battery cell, thereby reducing the risk of short circuit of the battery.

[0003] The main body of the current glue sticking mechanism is usually composed of two vacuum glue suction blocks, which fix the two ends of the tape respectively, and then stick the tape to the weld surface close to the position where glue is needed.

[0004] At present, the position of the soldering protective tape in the production process of square batteries is usually a curved surface with a certain curvature, and the conventional glue sticking mechanism only clamps the two ends of the tape during glue sticking. Therefore, after glue sticking, the tape is generally in a taut state with the two ends tightly attached and the middle suspended. If the tape suspended in the middle touches the pole ear, it will pull the pole ear, causing the pole ear to break, affecting the battery performance. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a gluing mechanism for square batteries, which is used for gluing tape 102, and includes:

[0024] The adhesive suction block 101 and the tape clamping mechanism act on both ends of the adhesive tape 102 to fix it;

[0025] The adhesive roller 105 is disposed below the adhesive tape 102 and abuts against the adhesive tape 102 , and rolls from one end of the adhesive tape 102 to the other end to abut the adhesive tape 102 against the surface of the object to be adhered.

[0026] In the present embodiment, when applying glue, one end of the tape 102 is firstly applied to the surface of the object by means of the glue suction block 101, and the other end of the tape 102 is clamped by the clamping mechanism. Then, the glue applying roller 105 is used to press on the tape 102 and roll it from one end to the other end, so that the tape 102 is gradually applied to the surface of the object, thereby reducing the risk of the tab being pulled and torn by the tape 102, increasing the production yield, and improving the battery performance.

[0027] In one embodiment, the entrainment mechanism includes a lower rod 104 and an upper rod 103 , and both the lower rod 104 and the upper rod 103 can rotate freely around their respective central axes.

[0028] This embodiment is configured such that the lower rod 104 and the upper rod 103 can provide a stable clamping effect for the tape 102 to avoid the problem of the tape 102 falling off. The two can rotate freely around the central axis to ensure that the tape 102 will not be pulled during the adhesive application process.

[0029] Specifically, the upper rod 103 is installed through the bracket 112 .

[0030] In one embodiment, the surface of the lower rod 104 is a smooth structure, and the surface of the upper rod 103 is a threaded structure.

[0031] This embodiment is configured such that the lower rod 104 contacts the non-adhesive side of the tape 102, and the upper rod contacts the adhesive side of the tape 102. The threads on the surface of the upper rod 103 can prevent the tape 102 from adhering to its surface.

[0032] In one embodiment, both ends of the lower rod 104 are connected to the first support rod 110, and the first support rod 110 is connected to the first cylinder 107. This embodiment is arranged so that before the tape 102 is applied, enough space is released to install the tape 102, and the distance from the upper rod 104 can be adjusted during the process, so as to achieve a better effect of clamping the tape 102.

[0033] In one embodiment, the first support rod 110 is a telescopic structure, and a spring is sleeved on the outside. This arrangement of the embodiment can make the lower rod 104 and the upper rod 103 closer, which is conducive to clamping the tape 102.

[0034] In one embodiment, the glue sucking block 101 is controlled to rise and fall by the second cylinder 106. This embodiment is configured in this way to facilitate adjusting the position of the glue sucking block 101 according to the position of the object to be attached, so as to meet different processing requirements.

[0036] Specifically, the guide groove 114 is provided on the base 113 ; the linear drive mechanism 108 can adopt a servo motor, a linear motor, a cylinder or the like.

[0037] This embodiment is configured such that after the two ends of the adhesive tape 102 are fixed, the linear drive mechanism 108 controls the slider 109 to move in the guide groove 114, driving the adhesive roller 105 to press the adhesive tape 102 against the surface of the object to be adhered.

[0038] In one embodiment, the second support rod 111 is a telescopic structure, and a spring is sleeved on the outside. This embodiment is arranged so that the glue-applying roller 105 and the adhesive tape 102 can be closely attached to facilitate glue-applying.

[0039] In one embodiment, the adhesive suction block 101 fixes one end of the adhesive tape 102 by vacuum absorption.
