Description

Technical Field

[0001] This utility model belongs to the field of battery production and conveying technology, and in particular relates to a battery positioning mechanism for a battery cover closing machine. Background Technology

[0002] In the battery manufacturing process, the battery case cover is a crucial step. Traditional production lines often use conveyors with fixed baffles or simple clamps to position the batteries. However, this method has a significant drawback: when one side has a movable gripper or pusher mechanism, during the positioning and battery release process, the battery is often pulled away from its designated position by the movable baffle due to adsorption or friction between the battery and the baffle. This movement causes the battery to malfunction within the conveyor system, as shown in the attached instruction manual. Figure 7 The observed deviation phenomenon indicates that the battery is stuck on the conveyor line, causing production interruption and severely affecting production efficiency and product yield. Utility Model Content

[0003] The purpose of this utility model is to provide a battery positioning mechanism for a cover-closing machine. By setting an anti-deviation mechanism consisting of a sleeve A, a spring A, a movable rod group, an annular limiting groove, and a movable pin, the movable rod group can temporarily hold the battery in place when the telescopic cylinder A retracts and the movable baffle moves backward. This effectively solves the problem of the movable baffle causing the battery to deviate due to adhesion or friction, and avoids production interruption and battery jamming.

The end of the movable pin passes through the through hole and is inserted into the annular limiting groove. By setting up an anti-deviation mechanism composed of sleeve A, spring A, movable rod assembly, annular limiting groove and movable pin, the battery can be temporarily held in place by the movable rod assembly when the telescopic cylinder A retracts and the movable baffle moves backward.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Please see Figure 1-3 As shown, this utility model is a battery positioning mechanism for a battery cover closing machine, including positioning mechanism A1 and positioning mechanism B2 respectively disposed on both sides of the frame of conveyor 3. Positioning mechanism B2 includes a fixed baffle 20 fixedly mounted on the frame by a bracket. A limiting baffle A21 is vertically fixed at the end of the fixed baffle 20 away from the feed end of conveyor 3, which is used to limit one corner of the battery in the width and length directions. Positioning mechanism A1 includes a base 10 fixed on the frame. A telescopic cylinder A11 is fixed on the base 10. The end of the telescopic cylinder A11 is connected to a movable baffle 13. A limiting baffle B12 is disposed at the end of the movable baffle 13 near the feed end of conveyor 3.

[0017] Working principle: In the initial state, the telescopic cylinder A11 is in the retracted state, and the movable baffle 13 and its limiting baffle B12 are away from the positioning mechanism B2. When the battery is fed into the conveyor 3 by the upstream conveying equipment and moves to the predetermined work position, the control system controls the telescopic cylinder A11 to extend. At this time, the movable baffle 13 is driven to move towards the fixed baffle 20 until the battery is clamped between the movable baffle 13 and the fixed baffle 20, and at the same time, its two adjacent sides contact the limiting baffle B12 and the limiting baffle A21 respectively. At this time, the battery is completely confined within the rectangular area enclosed by the fixed baffle 20, the limiting baffle A21, the movable baffle 13, and the limiting baffle B12, completing precise positioning for subsequent lid-opening operations.

[0018] After completing the precise positioning and lid-closing operation, when the telescopic cylinder A11 retracts to move the movable baffle 13 away from the fixed baffle 20, to prevent the battery from shifting on the conveyor surface of the conveyor 3 due to possible adhesion during the movement of the movable baffle 13, sleeves A14 are respectively installed on the bases 10 on both sides of the telescopic cylinder A11. A movable rod assembly 15 is connected to the sleeve A14 via a spring A154. A limiting ring 151 is provided around the movable rod assembly 15. A through hole is provided on the movable baffle 13 for the movable rod assembly 15 to pass through. A through hole is provided on the side wall of the sleeve A14, and an annular limiting groove 153 is provided on the movable rod assembly 15. A movable pin 162 is fixed on the base 10 on one side of the sleeve A14. The end of the movable pin 162 passes through the through hole and inserts into the annular limiting groove 153. In other words, when the telescopic cylinder A11 is fully extended during use, the movable pin 162 is pulled out from the annular limiting groove 153. At this time, under the action of the spring A154, the movable rod assembly 15 is moved until the end of the movable rod assembly 15 passes through the through hole and abuts against the outer wall of the battery. After the cover is closed, when the telescopic cylinder A11 retracts, it remains stationary in the early stage of retraction. At this time, the movable baffle 13 will not cause the battery to move on the conveying surface of the conveyor 3 due to the adhesion of the battery. After the telescopic cylinder A11 continues to retract, the movable baffle 13 abuts against the limiting ring 151, driving the movable rod assembly 15 to retract into the sleeve A14 until the annular limiting groove 153 moves to the through hole position. Then, the movable pin 162 is inserted into the annular limiting groove 153 for limiting.

[0019] The movable lever assembly 15 can be implemented in two preferred ways: Method 1: For example Figure 5 The movable rod assembly 15 includes an integrally formed rod body A150 and rod body B152, and an annular limiting groove 153 is formed on the rod body B152.

[0020] Method 2: For example Figure 6The movable rod assembly 15 includes a rod body A150, one end of which is located inside the sleeve A14 and connected to a rod body B152 via a spring B155; an annular limiting groove 153 is formed on the rod body B152, which can provide a certain buffer and reduce the rigid impact on the outer wall of the battery when the rod body A150 abuts against the outer wall of the battery.

[0021] The specific implementation principle of the movable lever assembly 15 in method two is as follows: In the initial stage when the telescopic cylinder A11 pushes the movable baffle 13 out, the entire movable rod assembly 15 protrudes beyond the plane of the movable baffle 13 under the preload of the spring A154. As the movable baffle 13 continues to move forward, the movable rod assembly 15 does not move until the movable baffle 13 contacts the battery casing. At this point, the restriction on the rod B152 is released, and under the action of the spring A154, the movable rod assembly 15 moves again towards the side closer to the movable baffle 13. Compared with the first method, the movement distance of the movable rod assembly 15 is shorter during this process, which reduces the impact of the movable rod assembly 15 on the battery.

[0022] Based on the above, the length direction of the movable pin 162 provided in this application is perpendicular to the length direction of the movable pin 162; and a drive mechanism is also provided that is connected to the movable pin 162 and drives the movable pin 162 to move back and forth along its own length direction. In order to facilitate the control of the movement of the movable pin 162, the drive mechanism can adopt two preferred embodiments.

[0023] Method 1: The driving mechanism is an independent telescopic cylinder B, with one end of the movable pin 162 directly fixed to the piston rod of the telescopic cylinder B. The insertion and withdrawal of the movable pin 162 are driven by controlling the extension and retraction of the telescopic cylinder B.

[0024] Method 2: For example Figure 4The driving mechanism includes a sleeve B16, a movable pin 162 inserted into the sleeve B16, and a spring C161 connecting the two; it also includes a connecting rod 17 fixed to the outer wall of the limiting baffle B12, the end of the connecting rod 17 being connected to a movable rod 171 that movably passes through the sleeve B16; a driving block 172 is provided at the end of the movable rod 171, and an inclined surface A173 is provided on the side of the driving block 172 away from the sleeve A14; a rectangular hole 163 is provided on the movable pin 162 for the driving block 172 to slide into it, and the rectangular hole 163 is located at the end of the sleeve B16. A ramp B164, which mates with ramp A173, is provided on one side of sleeve A14; a guide hole 165, which mates with movable rod 171, is provided on the side of sleeve B16 near the limiting baffle B12; an opening 166, for drive block 172 to pass through, is provided on the other side of sleeve B16; and a guide ramp 167 is provided on the end of movable pin 162 near movable baffle 13. During use, as telescopic cylinder A11 extends, connecting rod 17 and movable rod 171 move synchronously, and drive block 172 passes through... The sleeve B16 has an opening 166 on its side wall, which is inserted into a rectangular hole 163 at the end of the movable pin 162. As it continues to advance, the inclined surface A173 of the drive block 172 interacts with the inclined surface B164 in the rectangular hole 163, generating a lateral force that overcomes the elastic force of the spring C161, controlling the movable pin 162 to move away from the sleeve A14. At this time, the movable pin 162 is pulled out of the annular limiting groove 153. During the retraction of the telescopic cylinder A11, when the drive block 172 slides from the opening 166... When the cylinder extends, the inclined planes A173 and B164 gradually lose their fit, and the movable pin 162 moves towards the side closer to the sleeve A14 until the end of the movable pin 162 abuts against the outer wall of the rod body B152. When the telescopic cylinder A11 is fully retracted, the annular limiting groove 153 moves to the through hole position. At this time, the movable pin 162 moves and inserts into the annular limiting groove 153 to complete the limiting. This method uses the positioning action itself as a trigger signal to realize fully automatic mechanical linkage without the need for additional control components, which is low in cost and highly reliable.
