Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery production, in particular to a feeding platform for a lead-acid battery acid adding machine. Background Art

[0002] When adding acid to a battery, especially a lead-acid battery, acid adding equipment is required. The existing acid adding mechanism of the acid adding equipment generally includes an acid injection head. During operation, the conveyor belt first transports the battery to be acid-injected to the acid adding station under the acid injection head of the acid adding mechanism, that is, directly below the acid injection head. The acid injection head corresponds to the acid injection hole of the battery to be acid-injected. Then, the acid injection head descends into the acid injection hole to complete the acid adding process. After the acid injection is completed, the conveyor belt transports the battery after acid injection out. The existing acid adding mechanism of the acid adding equipment has the following problems: the structural design is not reasonable enough, the degree of automation is low, the labor intensity of the operator is high, the work efficiency is low, and safety accidents are likely to occur during the operation process.

[0003] A patent document with the publication number of CN211455830U discloses an automatic acid adding machine feeding device. This device uses the battery case that enters the limiting device later to push out the battery case that has been acid-added from the limiting device. There is no need to set a clamping mechanism. The overall structure is simple, effectively reducing the production cost, and it is convenient for maintenance and repair. By setting a stop bar, the positioning accuracy of the battery case is increased, and the phenomenon of acid leakage can be prevented when the automatic acid injection head is working. However, this device needs to set a stop bar driven by multiple rear telescopic cylinders above the second conveyor belt. The stop bar is used to block the battery that has completed acid addition, and then position the battery that subsequently enters the acid adding station. After the battery that subsequently enters the acid adding station is positioned, the stop bar is restored and the second conveyor belt is used to transport the battery that has completed acid addition away. When positioning the battery that enters the acid adding station and when transporting the battery on the second conveyor belt, it is necessary to make the rear telescopic cylinder drive the stop bar to move, resulting in high energy consumption during the acid adding process.

[0004] A lead-acid battery acid addition device is disclosed in the patent document with the publication number CN221080301U. This device has improved the battery loading structure. During operation, an operator first places multiple batteries separately in the limiting device, making the batteries in the limiting device correspond to the acid addition heads above them. Then, the upper air cylinder is started, causing the acid addition heads to descend and add acid to the batteries below. After the acid addition is completed, the acid addition heads return to their original positions. The batteries are placed one by one on the rear conveyor belt, and the blocking devices on the rear conveyor belt intercept the batteries on the rear conveyor belt in sequence. At this time, the batteries on the rear conveyor belt correspond to the batteries that have been acid-added in the limiting device. The lower air cylinder is started, and the lower air cylinder drives the batteries on the rear conveyor belt to move forward. When the batteries on the rear conveyor belt enter the limiting device, the acid-added batteries are pushed onto the front conveyor belt and blocked by the universal balls on the moving rod on the front side. At this time, the batteries in contact with the universal balls can block and limit the batteries in the limiting device. The batteries in the limiting device correspond to the acid addition heads above them. Starting the upper air cylinder can cause the acid addition heads to descend and add acid to the batteries in the limiting device. After the acid addition is completed, the front conveyor belt starts, and the front conveyor belt can convey the batteries on it to the right side. When the battery on the left side of the guide plate contacts the inclined part of the guide plate, the inclined part of the guide plate can guide the battery forward. Since the front end of the straight part of the guide plate is flush with the front end of the battery in the limiting device on its right side, it can prevent the battery on the left side of the guide plate from being blocked by the battery in the limiting device on the right side of the guide plate 11 during the process of moving to the right. This device does not need to set a blocking rod that can move back and forth above the front conveyor belt. During the acid addition process, only the lower air cylinder needs to drive the push rod assembly on the rear conveyor belt to move to achieve the positioning of the battery. The energy consumption and failure rate are low during the acid addition process of the battery. However, this device needs to set multiple blocking devices. During loading, the blocking devices act in sequence to intercept the batteries on the rear conveyor belt, so the input cost of this device is relatively high. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is an upper feeding platform for a lead-acid battery acid addition machine that can reduce the equipment input cost.

The positioning member includes two fixing plates arranged symmetrically left and right. The fixing plates are fixedly connected to the flat plate. A battery-adding cavity for accommodating the battery is formed between the two fixing plates of the same positioning member. A push rod is arranged above the first conveyor belt. The push rod is horizontally arranged. An electric telescopic rod is fixed on the bracket. The electric telescopic rod is vertically arranged. The telescopic end of the electric telescopic rod is fixedly connected to the push rod. A stop rod is fixedly connected to each push rod on the right side of the adding cavity. The left end of the stop rod is flush with the left end of the fixing plate on the right side of its corresponding positioning member. The stop rod is perpendicular to the push rod. The lengths of the plurality of stop rods increase sequentially along the conveying direction of the first conveyor belt. A horizontal blocking rod is arranged above the second conveyor belt. The blocking rod is connected to a driving component. A photoelectric sensor is fixed on the bracket on the left side of the push rod. The photoelectric sensor, the controller and the electric telescopic rod are electrically connected. The controller can make the blocking rod approach or move away from the platform through the driving component.

[0008] Specifically, guiding inclined surfaces are processed at the ends of the two fixing plates of the same positioning member facing the first conveyor belt.

[0009] Specifically, the driving component includes a cylinder fixed on the bracket. The cylinder is vertically arranged. The telescopic end of the cylinder is fixedly connected to the blocking rod. The solenoid valve controlling the cylinder is electrically connected to the controller.

[0010] Specifically, the heights of the lower ends of the push rod and the stop rod are greater than the height of the upper end of the fixing plate.

[0011] Specifically, both the first conveyor belt and the second conveyor belt are plastic conveyor belts.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the cooperation of the photoelectric sensor, the controller, the electric telescopic rod, the push rod and the stop rod in this device, after the photoelectric sensor senses the battery, the electric telescopic rod drives the push rod and the stop rod to move a certain distance towards the flat plate direction, so that the plurality of stop rods from right to left sequentially block the battery. There is no need to set multiple blocking devices, which can reduce the equipment investment cost.

[0014] 2. After multiple batteries are sequentially blocked by multiple stop rods, the batteries are simultaneously pushed into the corresponding adding cavities. Under the limiting action of the push rod and the blocking rod, the position of the battery in the front and back directions in the adding cavity can be controlled, which can ensure accurate acid addition to the battery by the acid addition head.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Embodiment 1: Refer to Figure 1 - Figure 2 As shown, a feeding platform for a lead-acid battery acid addition machine includes a bracket. Two horizontally arranged first conveyor belts 1 and second conveyor belts 2 are installed on the bracket. A flat plate 3 is fixedly connected to the bracket between the first conveyor belt 1 and the second conveyor belt. The upper end of the flat plate 3 is flush with the upper ends of the first conveyor belt 1 and the second conveyor belt 2. Specifically, the first conveyor belt 1 and the second conveyor belt 2 are both plastic conveyor belts. The plastic conveyor belt has good corrosion resistance, and when pushing the battery, the battery is easy to slide on the plastic conveyor belt.

[0020] A plurality of positioning members are arranged in the horizontal direction at the upper end of the flat plate 3. The positioning member includes two fixed plates 9 arranged symmetrically left and right. The fixed plates 9 are fixedly connected to the flat plate 3, and an acid addition chamber 10 for accommodating the battery is formed between the two fixed plates 9 of the same positioning member.

[0021] A push rod 4 is arranged above the first conveyor belt 1. The push rod 4 is horizontally arranged. An electric telescopic rod 5 is fixed on the bracket. The electric telescopic rod 5 is vertically arranged, and the telescopic end of the electric telescopic rod 5 is fixedly connected to the push rod 4.

[0022] Stop bars 6 are fixedly connected to the push rod 4 on the right side of the acid addition chamber 10. The left end of the stop bar 6 is flush with the left end of the fixed plate 9 on the right side of its corresponding positioning member. The stop bar 6 is perpendicular to the push rod 4, and the lengths of the plurality of stop bars 6 increase in sequence along the conveying direction of the first conveyor belt 1.

[0023] The height of the lower ends of the push rod 4 and the stop bar 6 is greater than the height of the upper ends of the fixed plates 9.

[0024] A photoelectric sensor 11 is fixed on the bracket on the left side of the push rod 4. The photoelectric sensor 11, the controller and the electric telescopic rod 5 are electrically connected.

[0025] Above the second conveyor belt 2, a transverse blocking rod 7 is provided, and the blocking rod 7 is connected to the driving assembly. The controller can make the blocking rod 7 approach or move away from the platform through the driving assembly. Specifically, the driving assembly includes a cylinder 8 fixed on the bracket. The cylinder 8 is longitudinally arranged, and the telescopic end of the cylinder 8 is fixedly connected to the blocking rod 7. The solenoid valve controlling the cylinder 8 is electrically connected to the controller.

[0026] Through the cooperation of the photoelectric sensor 11, the controller, the electric telescopic rod 5, the push rod 4, and the blocking rod 6, after the photoelectric sensor 11 senses the battery, the electric telescopic rod 5 drives the push rod 4 and the blocking rod 6 to move a certain distance in the direction of the flat plate 3, so that a plurality of blocking rods 6 from right to left sequentially block the battery. There is no need to set up multiple blocking devices, which can reduce the input cost of the equipment.

[0027] In this embodiment, the number of blocking rods 6 is four. The first battery entering the first conveyor belt 1 is blocked by the rightmost blocking rod 6. As Figure 2 shown, when the second battery entering the first conveyor belt 1 is sensed by the photoelectric sensor 11, the electric telescopic rod 5 drives the push rod 4 and the blocking rod 6 to move a certain distance in the direction of the flat plate 3 again, and the second battery entering the first conveyor belt 1 is blocked by the second blocking rod 6 from right to left. Figure 1 and Figure 2 The dotted lines in are the movement trajectories of the first conveyor belt 1 driving the battery to move.

[0028] When the four batteries on the first conveyor belt 1 are respectively blocked by the four blocking rods 6, the electric telescopic rod 5 drives the push rod 4 and the blocking rod 6 thereon to move in the direction of the flat plate 3, and then pushes the battery into its corresponding acid adding cavity 10. Then the cylinder 8 drives the blocking rod 7 to move in the direction of the flat plate 3, and the blocking rod 7 tightly abuts against the battery. When the blocking rod 7 and the push rod 4 tightly abut against the front and rear ends of the battery, the position of the battery in the front and rear directions in the acid adding cavity 10 is determined. Then the battery in the acid adding cavity 10 can be acid added by using an acid adding head.

[0029] After the battery acid adding is completed, the cylinder 8 drives the blocking rod 7 to return, and the electric telescopic rod 5 drives the push rod 4 and the blocking rod 6 to continue to move in the direction of the second conveyor belt 2. When the battery is pushed out of the acid adding cavity 10 and enters the second conveyor belt 2, the electric telescopic rod 5 drives the push rod 4 and the blocking rod 6 to return, and then the battery is conveyed by the second conveyor belt 2 to the next processing station.

[0030] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 and Figure 2 shown, guide inclined surfaces are processed at the ends of the two fixed plates 9 of the same positioning member facing the first conveyor belt 1. By arranging the guide inclined surfaces on the fixed plates 9, it is convenient for the battery to enter the acid adding cavity 10 between the two fixed plates 9.
