Description

Technical Field

[0001] The invention relates to a method for preparing a lead-acid battery, in particular to a method for assembling a commercial vehicle battery pole group and an anti-vibration frame into a slot, and belongs to the technical field of lead-acid batteries. Background Art

[0002] With the continuous development of new models of commercial vehicles (i.e. trucks), the vibration resistance of commercial vehicle batteries is increasingly required. The current technical solutions such as fixing the pole group with glue at the bottom and fixing the pole group on both sides of the pole group with plug side frames can no longer meet the vibration resistance requirements of commercial vehicle batteries. Vibration failure has become a major cause of the shortened life of lead-acid batteries for commercial vehicles. The main manifestations of battery vibration failure are: the plate ears break from the bus connection, the pole plates are damaged or broken, etc. The above problems of batteries are mainly due to the objective thickness deviation between the pole plates, which leads to certain differences in thickness between different pole groups. The existing technical measures cannot actually achieve a good tight assembly effect for each pole group. Among them, the problem of the outer wall of the battery being deformed due to the over-tightening of the plugging frame will occur in the case of thicker pole groups; the problem of the outer wall of the battery being deformed due to the over-tightening of the plugging frame will occur in the case of relatively thin pole groups during battery use. When the horizontal vibration force of the vehicle is transmitted to the pole group inside the battery, the pole plates in the loose pole group will swing to a large extent. This large swing will generate large shear and tensile forces between the various parts inside the pole plate, especially between the bus and the plate ear and different parts of the pole plate itself, forming large shear and tensile forces. Over time, the pole group structure will be destroyed, causing vibration failure. Therefore, designing components with good anti-vibration effects is the key to avoiding vibration failure of commercial vehicle batteries. At the same time, with the improvement of the structure of battery anti-vibration components, the traditional battery slot technology cannot meet the requirements of high-efficiency production. Therefore, while developing battery anti-vibration components, it is also an indispensable technology to design a slot assembly method that meets the requirements of the battery production line.

DETAILED DESCRIPTION

[0031] The invention discloses an assembly method for completing an anti-vibration frame and automatic slotting of pole groups on a battery production line. The anti-vibration frame is specially designed to improve the anti-vibration performance of commercial vehicle batteries.

[0032] See also Figure 8-Figure 10, the anti-vibration frame 7 is made of PP material, reinforced PP material or ABS material with high elasticity and is injection molded in one step. The anti-vibration frame includes two symmetrically arranged side frames 7-1 and a connecting plate 7-2 connecting the two side frames by the upper part of the side frames. Sawtooth wing plates 7-4 are provided on both sides of each side frame, and teeth are distributed on the serrated wing plates. The top of each tooth is in arc transition, and a triangular introduction plate is provided at the bottom of the serrated wing plate to facilitate slot entry. The shape design of the tooth can reduce the friction between the pole group and the battery slot wall when entering the slot, and reduce the resistance of the anti-vibration frame in the process of entering the battery slot. The serrated wing plate is inclined relative to the side frame plate surface, and the angle α of the serrated wing plate relative to the side frame plate surface when not subject to external force is 120°-150°. An elastic support plate 7-5 is provided at the bottom of each side frame. The lower elastic support plates of the two side frames are distributed in an eight-shaped shape. When not subjected to external force, the angle β of the elastic support plate relative to the horizontal plane is 40°-50°, and the width dimension B of the elastic support plate is 8-10 mm. Support bosses 7-3 are provided on both sides of the top of each side frame. The four bosses on the two side frames correspond to the positive and negative busbars of the pole group, and play a role in positioning and supporting the anti-vibration frame in the vertical direction. The height of the support boss is 1-2 mm less than the height of the pole plate ear of the pole group. Several reinforcing ribs 7-6 are provided on the outer plate surface of each side frame, and a trapezoidal lead-in end is provided at the bottom of each reinforcing rib. The reinforcing ribs are used to strengthen the strength of the side frame. The positions of the reinforcing ribs and the reinforcing ribs on the inner wall of the battery slot are staggered to avoid the overlapping and extrusion of the reinforcing ribs on the side frame and the reinforcing ribs on the battery slot wall, causing deformation of the battery slot wall.

[0033] See also Figure 8-Figure 12 , the anti-vibration frame has a length dimension W1, a thickness dimension L1, a height dimension H1, and a distance L between the two side frames. The battery slot (single cell) has a length dimension W3, a thickness dimension L3, and a height dimension H3. The thickness dimension L2 of the pole group, the height dimension H2 of the pole group (plate height), and the dimensional relationship between the anti-vibration frame and the battery slot and pole group is as follows: L1 = L3 + (2 ~ 4) mm, H1 = H2 + (1 ~ 2) mm, W1 = W3 + (1 ~ 3) mm, L = L2 - (1 ~ 3) mm. After the two side frames wrap the pole group, the connecting plate is pressed on the upper part of the pole group. The connecting plate can elastically tighten the upper part of the pole group. At the same time, after entering the slot, the elastic support plate elastically tightens the bottom of the pole group under the extrusion force of the lower part of the battery slot wall, so that the pole plates are tightly assembled, avoiding looseness between the pole plates and preventing the swing of the pole plates during vibration from being damaged.

[0034] Since the structure of the anti-vibration frame is quite different from the traditional plugging frame, it is necessary to design a corresponding slotting assembly method to ensure that the pole group and the anti-vibration frame are automatically slotted on the battery production line. The method is implemented with the help of a pole group slotting device. Figure 1The pole group slot device is composed of a transfer mechanism I and a pole group slot mechanism II. The transfer mechanism is connected to the pole group slot mechanism, and the transfer mechanism carries the pole group slot mechanism to achieve the position change of the pole group slot mechanism up, down, left, right, front, and back. The transfer mechanism adopts the existing technology, and the pole group slot mechanism is the improvement focus of the present invention.

[0035] See also Figure 2 , Figure 3 , the slot entry mechanism device is provided with a support 1, a gripper, and a suction cup 3. The gripper is symmetrically provided with two clamping plates 4, and the suction cup is located between the two clamping plates. The support is also provided with a trapezoidal slider 2 which is small at the top and large at the bottom, and two wedges 6 which are symmetrically provided on both sides of the trapezoidal slider. The wedge is large at the top and small at the bottom, and the two sides of the trapezoidal slider correspond to the inclined surfaces of each wedge respectively. The middle and lower parts of each wedge are respectively hinged to the support, and the mass of the wedge at the upper part of the hinge position is significantly greater than the mass of the lower part. The lower part of each wedge is respectively fixed to the clamping plate, and each clamping plate is provided with a baffle 4-1 which limits the upward movement of the anti-vibration frame. The upper end of the trapezoidal slider is connected to the push-pull rod 5, and the lower end is connected to the suction cup 3, and the push-pull rod is connected to the cylinder of the transfer mechanism. When the trapezoidal slider is not in contact with the wedge block, the upper part of the wedge block rotates around the hinge point and tilts inward under the action of gravity, and the lower part of the wedge block and the clamping plate open outward, making it easier for the anti-vibration frame to enter between the two clamping plates; when the trapezoidal slider moves upward under the action of the cylinder, it pushes the upper parts of the two wedge blocks to open outward, and the lower part of the wedge block moves inward together with the clamping plate.

[0036] See also Figure 4-Figure 6 , the process of slotting the pole group and anti-vibration frame is as follows:

[0037] a. Transport the anti-vibration frame to the pole group slotting station, just below the pole group slotting mechanism.

[0038] b. The transfer mechanism I drives the pole group slot mechanism to move downward, and at the same time, the cylinder drives the push-pull rod to move downward, and the trapezoidal slider and the suction cup connected to the push-pull rod move downward together, the two clamping plates open outward, and the suction cup moves down to 1-2 mm below the baffle, so that the anti-vibration frame enters between the two clamping plates. When the suction cup is close to the connecting plate, the suction cup sucks up the anti-vibration frame 7 under the action of negative pressure, and the baffle plays a limiting role on the anti-vibration frame, such as Figure 4 shown.

[0039] c. The pole group slotting mechanism carries the anti-vibration frame and is transported by the conveying mechanism to the top of the pole group 9 that has been cast-welded. The conveying mechanism moves downward. In the process of the pole group entering between the two side frames of the anti-vibration frame, the two side frames are elastically opened outward by the top of the pole group bus. When the tops of the four supporting bosses on the anti-vibration frame are lower than the lower surface of the pole group bus, the conveying mechanism stops moving downward. At this time, the baffle 4-1 contacts the upper part of the pole group, and the two side frames are elastically retracted inward. The four supporting bosses 7-3 are located directly below the two ends of the bus 9-1, forming downward positioning and support for the anti-vibration frame. Both sides of the pole group 9 are completely wrapped by the side frames 7-1. Figure 5 , Figure 6 shown.

[0040] The pole group opens outwards, and when the pole group contacts the baffle, the transfer mechanism stops moving downward; at this time, the four support bosses 7-3 are located directly below the two ends of the bus 9-1, forming downward positioning and support for the anti-vibration frame, and the two sides of the pole group 9 are completely wrapped by the side frame 7-1, such as Figure 5 , Figure 6 shown.

[0041] d. The cylinder drives the push-pull rod to move upward, and the trapezoidal slider and the suction cup move upward accordingly. The suction cup is separated from the anti-vibration frame. At the same time, the trapezoidal slider touches and pushes the upper part of the two wedges outward, and the lower part of the wedge and the clamping plate are tightened inward to clamp the anti-vibration frame and the pole group. Figure 7 The transfer mechanism moves the pole group slotting mechanism, the anti-vibration frame and the pole group to the top of the battery slot, the push-pull rod moves downward, the clamping plate is released, and under the guidance of the triangular lead-in plate at the bottom of the sawtooth wing plate, the anti-vibration frame and the pole group wrapped therein fall into the upper opening of the battery slot and are centered, the transfer mechanism and the slotting mechanism are moved away, and then the pole group and the anti-vibration frame are pressed into the battery slot together by the slotting pressing device on the pole group casting welding machine to complete the pole group slotting.

[0042] The above process can be completed by the automatic control system of the Jiqun casting welding line, thereby greatly improving production efficiency and reducing manual labor intensity.

[0043] The state of the pole group and the anti-vibration frame after entering the slot is as follows Fig.13 As shown. After the pole group and the anti-vibration frame are put into the slot, the elastic support plate forms an elastic extrusion on the pole group under the extrusion of the reinforcement ribs on the inner wall of the battery slot, ensuring the tight assembly of the lower part of the pole group. The serrated wing plate points to the four inner corners of the battery slot, the teeth are in contact with the corners of the battery slot wall, the serrated wing plate is bent, and the end is just supported at the four inner corners of the battery slot, playing the role of supporting and fixing the pole group in the horizontal direction, preventing the pole group from swinging when the battery vibrates horizontally. The serrated wing plate automatically adjusts the tightness of the pole group under the action of the four inner corners of the battery slot through its own elastic deformation characteristics, ensuring the tight assembly of pole groups of different thicknesses. Preventing the pole group from swinging relatively sharply relative to the battery slot, thereby avoiding damage to the pole plate. At the same time, it also avoids deformation of the outer wall of the battery.
