Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to an automatic loading mechanism for medium and large density batteries. Background Technology

[0002] Currently, in the production process of large lead-acid batteries, a crucial step is loading the batteries, after the acid-adding process, into a charging tank filled with coolant. The industry generally adopts a manual sliding plate operation mode, where operators move the acid-adding batteries to the end of the tank. Using specially designed sliding plates or pry bars, workers manually push or slide the heavy batteries one by one along the inclined edge or track into the preset slots in the electrolyte-filled tank. To ensure the positional accuracy of the batteries in the tank and to leave space for electrical connections, operators need to frequently manually adjust the spacing between the batteries.

[0003] The existing patent application, with publication number CN204980150U and publication date January 20, 2016, is titled "An Automatic Conveying Device for Internal Formation of Lead-Acid Batteries." This patent includes an automatic transmission line arranged on one side of rows of internal formation tank supports. An automatic transport trolley is located between the internal formation tank supports and the automatic transmission line. The automatic transport trolley contains an automatic walking mechanism, a power battery box, and a lifting mechanism. The lifting mechanism includes a lifting platform that can align with the movement of the internal formation tanks and the automatic transmission line. The lifting platform contains a lifting drive motor connected to the battery box. The automatic transport trolley also includes a detection device for detecting the coding devices on the internal formation tank supports and an automatic control device. The automatic control device controls the lifting drive motor. This utility model's automatic transport trolley can automatically operate between the various internal formation tank supports where batteries need to be transported, facilitating the pushing of multiple lead-acid batteries onto the internal formation tanks and the automatic transmission line. Transporting lead-acid batteries is automated and labor-saving, improving production efficiency.

[0004] The aforementioned applications have shortcomings. When hydraulic and pneumatic grippers hold large-density batteries, they are prone to slight backsliding during lifting or transfer due to the battery's own weight and motion inertia. This can lead to loosening of the gripper, causing the battery to shift position or even fall. In particular, under frequent start-stop conditions, pressure fluctuations in the hydraulic system can exacerbate gripping instability. Furthermore, some mechanisms that use purely mechanical locking require additional solenoid valves or pin devices to prevent gripper backsliding. This not only occupies space and increases costs but also prolongs the operation cycle due to poor coordination among multiple components, and poses a risk of accidental triggering or unlocking jamming. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic battery loading mechanism for medium and large-density batteries to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic battery loading mechanism for medium and large density batteries includes a belt conveyor and a transfer mechanism, as well as a hydraulic lifting platform installed within the transfer mechanism. A clamping base is fixedly connected to the bottom of the hydraulic lifting platform. Several sets of symmetrically moving hydraulic clamping components and a pressure check mechanism are installed within the clamping base, which penetrates the clamping base and is inserted into the top of the hydraulic clamping components. An abutment is installed between each set of hydraulic clamping components. The bottom of the abutment elastically abuts against the pressure check mechanism, and the top of the abutment engages with the transfer mechanism. When each set of hydraulic clamping components clamps a battery and is driven upwards by the hydraulic lifting platform, the abutment presses down on the pressure check mechanism, restricting the hydraulic clamping components from moving back. When the hydraulic lifting platform descends, the extension and retraction of the hydraulic clamping components cause the pressure check mechanism to reciprocate upwards and downwards.

[0008] Preferably, the transfer mechanism includes a track frame erected outside the belt conveyor and a transfer trolley that moves horizontally along the track frame. The transfer trolley is symmetrically equipped with drive shafts, and limit guide wheels are fixedly connected to both ends of the drive shafts. An outer transfer base is slidably installed in the transfer trolley, and the hydraulic lifting seat is connected to the bottom of the outer transfer base through multiple hydraulic telescopic rods.

[0009] Preferably, a drive motor is installed on one side of the transfer trolley, and a transmission screw is installed on the output shaft of the drive motor. A threaded sleeve sleeved on the outside of the transmission screw is fixedly connected to the top of the outer moving base. A buffer plate is elastically connected to one side of the transfer trolley located in the unloading area. A counterweight block is vertically slidably installed on one side of the buffer plate. When the outer moving base moves to the unloading area, it lifts up the counterweight block.

[0010] Preferably, a frame is installed on one side of the transfer trolley above the belt conveyor, and several electric push rods and stop rods are hinged inside the frame. The head of the electric push rod is connected to the hinged end of the stop rod, and the hydraulic clamping components and stop rods are alternately distributed along the conveying direction.

[0011] Preferably, the hydraulic clamping component includes a hydraulic push rod fixed to the side wall of the clamping base, a clamping plate fixedly connected to the end of the hydraulic push rod, and an anti-slip pad installed on the inner side of the clamping plate.

[0012] Preferably, the abutment check mechanism includes a U-shaped bracket that is elastically inserted into the top of the clamping plate. The top of the clamping plate has symmetrically opened insertion holes for inserting the U-shaped bracket. The clamping base has a pair of guide grooves for the U-shaped bracket to pass through. The top of the inner wall of the U-shaped bracket is embedded with abutment teeth. The top surface of the clamping base is fixedly connected with a check rack that abuts and cooperates with the abutment teeth.

[0013] Preferably, the abutting member includes a column that penetrates the clamping base and the hydraulic lifting seat. A pressure plate is fixedly connected to the bottom of the column inside the clamping base. The pressure plate is located above each set of hydraulic clamping members. An elastic pressure rod is slidably installed inside the U-shaped bracket. The elastic pressure rod is located between the pressure plate and the clamping plate. An inclined pressure groove is provided on the outer side of the clamping plate to abut against the elastic pressure rod.

[0014] Preferably, the column outer sleeve is provided with a return spring and a limiting ring, the limiting ring is in contact with the bottom surface of the hydraulic lifting seat, and the return spring is located between the limiting ring and the clamping base.

[0015] Preferably, a connecting frame is fixedly connected to the bottom of the external base, and several sleeves are installed at the bottom of the connecting frame. A compressed air bladder with a bottom opening is installed inside the sleeve. A pressure plate is fixedly connected to the top of the column, and an air supply chamber corresponding to the opening of the compressed air bladder is opened in the middle of the column.

[0016] Preferably, both sides of the clamping plate are slidably fitted with locking members that are inserted into the back of the anti-slip pad, and the top of the locking member is located in the insertion hole and is limited by the U-shaped bracket.

[0017] In the above technical solution, after the hydraulic clamping components are clamped, they are driven to rise as a whole by the hydraulic lifting seat. At this time, the abutment is pressed down by the transfer mechanism, which forces the pressure check mechanism to elastically press against the top of the hydraulic clamping components downward, forming a physical lock and eliminating the risk of the gripper shifting back. The pressure check mechanism passes through the clamping base and is directly inserted into the clamping components, eliminating the need for an additional locking device. The check action is naturally triggered by the pressure of the abutment, without the need for independent control components. When the hydraulic lifting seat descends, the retraction action of the clamping components is linked to the pressure check mechanism to reciprocate up and down, releasing the locked state. At the same time, the abutment automatically resets, allowing the hydraulic clamping components to freely extend and retract during the clamping and releasing process after descent. This allows the pressure check mechanism to provide a rigid stop during the locking phase and to provide continuous vibration to the hydraulic clamping components during the release phase, preventing debris from adhering to the clamping plate before clamping the battery and affecting the clamping stability.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0033] Please see Figure 1-9 This invention provides an automatic battery loading mechanism for medium and large density batteries, including a belt conveyor 1 and a transfer mechanism 2, and a hydraulic lifting seat 3 installed inside the transfer mechanism 2. A clamping base 4 is fixedly connected to the bottom of the hydraulic lifting seat 3. Several sets of symmetrically moving hydraulic clamping members 5 and a pressure check mechanism 6 are installed inside the clamping base 4, which passes through the clamping base 4 and is inserted into the top of the hydraulic clamping members 5. An abutment member 7 is installed between each set of hydraulic clamping members 5. The bottom of the abutment member 7 elastically abuts against the pressure check mechanism 6, and the top of the abutment member 7 abuts against the transfer mechanism 2. When each set of hydraulic clamping members 5 clamps the battery and is driven to rise by the hydraulic lifting seat 3, the abutment member 7 presses down on the pressure check mechanism 6 to restrict the hydraulic clamping members 5 from moving back. When the hydraulic lifting seat 3 descends, the extension and retraction of the hydraulic clamping members 5 drives the pressure check mechanism 6 to reciprocate up and down.

[0034] Specifically, belt conveyor 1 is used to horizontally transport large lead-acid batteries that have completed the acid-addition process to a designated workstation. Transfer mechanism 2 is used to transfer multiple batteries arranged on belt conveyor 1 to a water tank. Hydraulic lifting seat 3 can slide in transfer mechanism 2 and is driven by hydraulic cylinders to rise and fall vertically. The lifting stroke matches the depth of the water tank. During operation, belt conveyor 1 transfers the batteries to the clamping workstation. After transfer mechanism 2 moves to the corresponding position, the hydraulic lifting seat 3 first drives the clamping base 4 to fall. Then, each set of hydraulic clamping components 5 moves synchronously to symmetrically clamp both sides of the battery. After falling, the backstop mechanism 6 is not triggered, allowing the hydraulic clamping components 5 to freely extend and retract to complete the adaptive clamping action. The clamping base 4, which clamps multiple batteries, is driven by hydraulic lifting seat 3 to rise as a whole, allowing the upper end of the contact component 7 to contact the battery. The transfer mechanism 2 forms a rigid physical lock by pressing down the anti-return mechanism 6 through the abutment member 7, completely eliminating the risk of accidental back movement of the hydraulic clamping member 5 due to battery gravity or vibration. No additional sensors or solenoid valves are required, and the reliability is extremely high. Then, the transfer mechanism 2 moves laterally to the target cell above the water tank. The locking state is maintained during the movement until the hydraulic lifting seat 3 carries the clamping base 4 into the water tank. Since the anti-return mechanism 6 releases the locking state after descent, each set of hydraulic clamping members 5 can retract freely to release the battery. During the retraction process of the hydraulic clamping member 5, the repeated reciprocating motion of the anti-return mechanism 6 in the released state can generate high-frequency micro-vibration of the hydraulic clamping member 5, shaking off electrolyte crystals or impurities attached to the surface of the hydraulic clamping member 5, avoiding slippage in the next clamping, and improving the reliability of continuous clamping.

[0035] Compared with the prior art, the present invention, through the symmetrical arrangement of hydraulic clamping members 5, after clamping the battery, is driven to rise as a whole by the hydraulic lifting seat 3. At this time, the abutment member 7 is pressed down by the transfer mechanism 2, forcing the pressure check mechanism 6 to elastically press against the top of the hydraulic clamping member 5 downward, forming a physical lock and eliminating the risk of the gripper shifting back. The pressure check mechanism 6 passes through the clamping base 4 and is directly inserted into the clamping member, eliminating the need for an additional locking device. The check action is naturally triggered by the elastic pressure of the abutment member 7, without the need for an independent control element. When the hydraulic lifting seat 3 descends, the retraction action of the clamping member is linked to the reciprocating rise and fall of the pressure check mechanism 6, releasing the locked state. At the same time, the abutment member 7 automatically resets, allowing the hydraulic clamping member 5 to freely extend and retract during the clamping and releasing process after descent. This allows the pressure check mechanism 6 to provide a rigid stop during the locking stage and to provide continuous vibration to the hydraulic clamping member 5 during the release stage, preventing debris from adhering to the clamping plate 502 before clamping the battery and affecting the clamping stability.

[0036] In a further embodiment of the present invention, the transfer mechanism 2 includes a track frame 201 erected outside the belt conveyor 1 and a transfer trolley 202 that moves along the track frame 201. Drive shafts 203 are symmetrically mounted on the transfer trolley 202, with limit guide wheels 204 fixedly connected to both ends of the drive shafts 203. An outer moving base 205 is slidably installed in the transfer trolley 202. A hydraulic lifting seat 3 is connected to the bottom of the outer moving base 205 via multiple hydraulic telescopic rods 301. Multiple water tanks are arranged along the moving track of the transfer trolley 202. Specifically, the track frame 201 is a steel truss spanning the periphery of the conveyor, with double linear guides laid on top. The guide wheel 204 on the transfer trolley 202 rolls along the linear guide rail. By moving the transfer trolley 202 above the belt conveyor 1, it can reach the corresponding clamping and loading position of the water tank on the belt conveyor 1 at any time. When lowering and clamping, each hydraulic telescopic rod 301 extends synchronously, allowing the hydraulic lifting seat 3 to move down with the clamping base 4. The battery is clamped by each set of hydraulic clamping parts 5. The drive shaft 203 provides rigid support and the hydraulic telescopic rod 301 provides floating connection. While ensuring the accuracy of heavy-load translation, it solves the problem of attitude self-adaptation during the process of large battery entering the tank. It improves efficiency compared to manual operation and achieves zero splash risk.

[0037] In a further embodiment of the present invention, a drive motor 206 is installed on one side of the transfer trolley 202, and a transmission screw 207 is installed on the output shaft of the drive motor 206. A threaded sleeve 208 is fixedly connected to the top of the outer moving base 205 and sleeved outside the transmission screw 207. A pair of limiting rods are also fixedly connected inside the transfer trolley 202. Anti-deviation sleeves are fixedly connected to the top of the outer moving base 205 and sleeved outside each limiting rod. A buffer plate 209 is elastically connected to one side of the transfer trolley 202 located in the unloading area. A counterweight block 210 is vertically slidably installed on one side of the buffer plate 209. A buffer spring 213 is symmetrically fixedly connected to the other side of the buffer plate 209 and abuts against the inner wall of the transfer trolley 202. The buffer spring 213 is sleeved outside the limiting rods. When the outer moving base 205 moves to the unloading area, it lifts the counterweight block. 210. Specifically, when it is necessary to adjust the lateral position of the grabbed battery, the drive motor 206 starts. Through the cooperation of the transmission screw 207 and the threaded sleeve 208, the rotational motion is converted into the linear displacement of the outer moving base 205, allowing the outer moving base 205 to slide laterally with the hydraulic lifting seat 3, realizing closed-loop displacement control and solving the problem of cumulative error in the water tank. When the outer moving base 205 moves to the battery release position, the top edge contacts the bottom slope of the counterweight block 210. The outer moving base 205 continues to rise and lift the counterweight block 210. The weight of the counterweight block 210 and the buffering effect of the buffer plate 209 ensure the stability of the battery during the process of entering the tank, and counteract the vibration generated by each component when the battery is released, preventing the hydraulic clamping component 5 from pushing the battery when it is removed from the battery in the water tank.

[0038] In a further embodiment of the present invention, a frame 8 is installed on one side of the transfer trolley 202 above the belt conveyor 1. Several electric push rods 801 and stop rods 802 are hinged within the frame 8. The heads of the electric push rods 801 are connected to the hinged ends of the stop rods 802. Hydraulic clamping components 5 and stop rods 802 are alternately distributed along the conveying direction. Specifically, each stop rod 802 rotates under the drive of the electric push rod 801. When the battery is on the belt conveyor 1, the stop rods 802 sequentially flip and block the incoming battery. Sufficient gaps are reserved between each battery and they are arranged in a way that allows each set of hydraulic clamps 5 in the clamping base 4 to simultaneously clamp the corresponding battery, so that there is adequate space between each battery placed in the water tank to facilitate the flow of cooling water during formation. At the same time, the belt conveyor 1 continues to run while the baffle 802 blocks the battery from moving forward. The friction between the baffle and the bottom of the battery allows one side of the battery to stick to the baffle 802, thereby correcting the battery's own orientation and solving the problem of accurate positioning of heavy batteries under high-speed transportation.

[0039] In a further embodiment of the present invention, the hydraulic clamping component 5 includes a hydraulic push rod 501 fixed to the side wall of the clamping base 4. A clamping plate 502 is fixedly connected to the end of the hydraulic push rod 501. The clamping plate 502 is located between two adjacent stop rods 802. An anti-slip pad 503 is installed on the inner side of the clamping plate 502. Specifically, when the clamping base 4 reaches a suitable height, the hydraulic push rods 501 of the two hydraulic clamping components 5 are controlled to bring the clamping plates 502 closer to each other. Then, the anti-slip pad 503 is used to increase the friction between the clamping component and the battery, improve the gripping force of the battery during the clamping process, and prevent the battery from loosening and shaking.

[0040] In a further embodiment of the present invention, the anti-return mechanism includes a U-shaped bracket 601 elastically inserted into the top of the clamping plate 502. The top of the clamping plate 502 has symmetrically arranged insertion holes 504 for inserting the U-shaped bracket 601. The clamping base 4 has a pair of guide grooves 401 for the U-shaped bracket 601 to pass through. An abutting tooth 602 is embedded in the top of the inner wall of the U-shaped bracket 601. A check-return rack 402 that abuts against the abutting tooth 602 is fixedly connected to the top surface of the clamping base 4. Specifically, the U-shaped bracket 601 passes through the guide grooves 401 and is inserted into the insertion hole 504 on the clamping plate 502, meaning it can pass through the guide grooves 401 to... To prevent the clamping plate 502 from shifting during movement and to ensure the free up-and-down movement of the U-shaped bracket 601, the hydraulic lifting seat 3 drives the clamping base 4 to descend. The clamping plate 502 and the abutment check mechanism descend synchronously. At this time, the abutment member 7 does not apply force to the U-shaped bracket 601 in the abutment check mechanism. With the extension and retraction of the hydraulic push rod 501, the clamping plate 502 moves back and forth with the U-shaped bracket 601. The abutment teeth 602 on the U-shaped bracket 601 contact the check rack 402 to achieve continuous vibration of the clamping plate 502, thereby cleaning the liquid or debris on the clamping plate 502 before clamping the battery.

[0041] In a further embodiment of the present invention, the abutting member 7 includes a column 701 that penetrates the clamping base 4 and the hydraulic lifting seat 3. A pressure plate 702 is fixedly connected to the bottom of the column 701 inside the clamping base 4. The pressure plate 702 is located above each set of hydraulic clamping members 5. An elastic pressure rod 603 is slidably installed inside the U-shaped bracket 601. The elastic pressure rod 603 is located between the pressure plate 702 and the clamping plate 502. Both ends of the elastic pressure rod 603 are fixedly connected to sliders 604. A vertical groove 605 matching the slider 604 is opened on the inner wall of the U-shaped bracket 601. A top spring 607 is fixedly connected to the bottom of the slider 604. An inclined pressure groove 505 that abuts and cooperates with the elastic pressure rod 603 is opened on the outer side of the clamping plate 502. Specifically, when the hydraulic lifting seat 3 drives the clamping base 4 to move upward, the top of the column 701 will contact the outward moving base 205 and cause the pressure plate 702 at the bottom of the column 701 to squeeze. A vertical downward pressure is applied to the top of the elastic pressure rod 603, forcing it to move downward within the clamping base 4 and wedging it into the inclined pressure groove 505 of the clamping plate 502. The lateral force pushes the clamping plate 502 slightly towards the battery side, increasing the hydraulic pressure of the clamping system. Simultaneously, the elastic pressure rod 603 pulls down the U-shaped bracket 601, causing the abutment teeth 602 in the U-shaped bracket 601 to wedge into the check rack 402, preventing the clamping claws from loosening and further ensuring the efficiency and stability of battery insertion. Through a combination of mechanical force amplification, elastic buffering, and gear locking mechanisms, dynamic locking is achieved without additional energy. After the clamping base 4 descends, the elastic pressure rod 603 can be lifted upward under the force of the top spring 607, thus preventing the elastic pressure rod 603 from squeezing the inclined pressure groove 505 and affecting the adjustment speed when the hydraulic clamping component 5 moves.

[0042] In a further embodiment of the present invention, a return spring 703 and a limiting ring 704 are provided on the outer sleeve of the column 701. The limiting ring 704 is fixed to the column 701, and the limiting ring 704 is in contact with the bottom surface of the hydraulic lifting seat 3 under the force of the return spring 703. The return spring 703 is located between the limiting ring 704 and the clamping base 4. Specifically, the return spring 703 lifts the limiting ring 704 to keep the column 701 at a certain height when it is not under pressure. During the process of the clamping base 4 lowering to clamp the battery, the column 701 pulls up the pressure plate 702 to prevent it from squeezing the elastic pressure rod 603, so that the anti-return mechanism 6 is in the unlocked state, so that the flexible adjustment and stable clamping of the hydraulic clamping component 5 can be quickly switched to adapt to the high-speed continuous battery insertion operation.

[0043] In a further embodiment of the present invention, a connecting frame 212 is fixedly connected to the bottom of the external base 205. Several sleeves 9 are installed at the bottom of the connecting frame 212. A compressed air bladder 901 with a bottom opening is installed inside the sleeve 9. A pressure plate 705 for squeezing the compressed air bladder 901 is fixedly connected to the top of the column 701. An air supply chamber 706 corresponding to the opening of the compressed air bladder 901 is opened in the middle of the column 701. Specifically, when the hydraulic clamping member 5 clamps the battery, the hydraulic lifting seat 3 drives the clamping base 4 to move upward. During this process, the compressed air bladder 901 filled with gas is squeezed by the pressure plate 705 on the column 701, and the discharged airflow can be blown towards the battery through the air supply chamber 706, thereby cleaning the dust on the top surface of the battery before it is transported to the water tank, so as to ensure the heat dissipation efficiency when it enters the water tank for formation.

[0044] In a further embodiment of the present invention, locking members 10 are slidably installed on both sides of the clamping plate 502 and inserted into the back of the anti-slip pad 503. The top of the locking member 10 is located in the insertion hole 504 and is limited by the U-shaped bracket 601. A plurality of snap-fit ​​strips 506 that snap into the clamping plate 502 are fixedly connected to the back of the anti-slip pad 503. The locking member 10 includes an insertion bracket 1001 connected to the clamping plate 502. A limiting pin 1002 that penetrates the snap-fit ​​strip 506 is fixedly connected to the inner side of the insertion bracket 1001. Specifically, if the anti-slip pad 503 is worn excessively, the upward height of the connector 1001 can be increased by lifting the corresponding U-shaped bracket 601. When the connector 1001 is at its highest point, the limit pin 1002 will disengage from the locking strip 506 on the anti-slip pad 503, allowing the anti-slip pad 503 to be quickly replaced. At the same time, the U-shaped bracket 601 can only be moved up to the corresponding unlocking height by individual operation, which can prevent the anti-slip pad 503 from accidentally falling off during normal operation and ensure the stability of clamping.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
