Description

Technical Field

[0001] The present invention belongs to the technical field of lithium-ion batteries, and in particular relates to an integrated device for loading and unloading polymer batteries. Background Art

[0002] In the polymer battery production process, the loading and unloading of X-ray inspection equipment currently relies entirely on manual operation. Specifically, two employees are required to manually load batteries from cassettes (trays) into the equipment's loading station, one by one, and remove the inspected batteries from the unloading station one by one and place them back on the tray. Because the loading and unloading stations are typically located on the same side of the equipment, the close proximity of two employees operating simultaneously is not only labor-intensive, but the frequent contact with the battery cells can easily cause cosmetic damage (such as scratches and dents), resulting in poor appearance.

[0003] This purely manual loading and unloading method in existing technology has significant shortcomings: First, it requires two employees to operate one piece of equipment, which consumes a lot of human resources. Second, manual operation is inefficient and difficult to maintain stably, especially after long periods of high-intensity work. Third, frequent manual contact with battery cells is a key factor in poor product appearance. Finally, this method has a very low degree of automation and cannot meet the modern industrial demand for efficient and stable production. Therefore, an automated solution is urgently needed to replace manual labor to improve efficiency, stabilize quality, save manpower, and ensure safety. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0020] The following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings and preferred embodiments.

[0021] As Figure 1As shown, it includes a lower frame 1, a pallet shaping and lifting mechanism 2, a pallet conveying mechanism 3, a battery loading and unloading conveying mechanism 4, a pallet buffer mechanism 5, an upper frame 6, a protective frame 7, and an original X-RAY equipment loading and unloading belt line 8 (included with the original equipment). The pallet shaping and lifting mechanism 2, the pallet conveying mechanism 3, the battery loading and unloading conveying mechanism 4, the pallet buffer mechanism 5, the upper frame 6, and the protective device 7 are installed on the lower frame 1. The original X-RAY equipment loading and unloading belt line 8 is completely covered by the protective frame 7, and the door opening device automatically stops to protect the safety of employees.

The base plate 101, lower frame door panel 103, foot cup 104, universal caster 105, power switch 106, air source processing triplex 107, and electrical wiring module 108 are attached to the 6060 square tube welded base 102. The insulation layer 109 is affixed to the base plate 101. The air source processing triplex 107 consists of a solenoid valve, a pressure reducing valve, and an oil and gas filter. The solenoid valve controls gas flow through electromagnetic principles, regulating gas pressure and direction. The pressure reducing valve regulates the pressure of the pneumatic system by reducing the high-pressure gas pressure by changing the flow cross-sectional area, thereby stabilizing the output pressure. The oil and gas filter removes impurities and moisture from the gas, improving its purity and stability and ensuring the proper operation of pneumatic equipment. The electrical wiring module 108 houses the programmable logic controller, expansion modules, power supplies, relays, circuit breakers, and other electrical components that control the entire device's electrical system. The insulation 109 prevents batteries from falling into the equipment, causing a short circuit and fire.

[0023] like Figure 3As shown in the figure, the pallet shaping and lifting mechanism 2 described in this patent includes a vertical plate support 201, a linear bearing block 202, a linear bearing 203, a guide post 204, a pallet shaping plate 205, a sensor bracket 206, a detection pallet in-place opposed sensor 207, a linear guide rail 208, a slider limit block 209, a support side bearing block 210, a fixed side bearing block 211, a ball screw 212, a ball screw nut bracket 213, a coupling 214, a servo motor 215, a lifting frame 216, a pallet presence / absence photoelectric sensor 217, an upper limit sensor 218, a lower limit sensor 219, a home sensor 220, and a pallet pick-and-place guide plate 221. Among them, the vertical plate support 201 and the pallet pick-and-place guide plate 221 are installed on the equipment base plate 101. The linear bearing block 202, the linear guide rail 208, the slider limit block 209, the support side bearing block 210, the fixed side bearing block 211, the upper limit sensor 218, the lower limit sensor 219, and the home sensor 220 are installed on the vertical plate support 201. The linear bearing 203 is installed on the linear bearing block 202. The guide post 204 passes through the linear bearing 203 and is connected to the pallet shaping plate 205. The sensor bracket 206 is installed on the pallet shaping plate 205. The detection pallet in-place opposed sensor 207 is installed on the sensor bracket 206. The ball screw 212 is installed in the support side bearing block 210 and the fixed side bearing block 211 and is connected to the coupling 214.

The lifting frame 216 is connected to the linear guide rail 208 and the ball screw nut bracket 213. The pallet presence / absence photoelectric sensor 217 is installed on the lifting frame 216.

[0024] The lifting frame 216 of the pallet shaping and lifting mechanism 2 described in this patent drags the loading pallet or the unloading pallet to move up and down within the range of the upper limit sensor 218 and the lower limit sensor 219 under the drive of the servo motor 215. After the detection pallet in-place opposed sensor 207 detects the pallet, the pallet stops rising or falling. After the pallet presence / absence photoelectric sensor 217 senses the absence of the pallet, the lifting frame 216 descends to the position of the home sensor 220.

[0025] The pallet shaping and lifting mechanism 2 described in this patent is characterized by having two sets in total. The left side is for automatic loading, and the right side is for automatic unloading. Among them, the pallet shaping plate 205 can be adjusted left and right to be suitable for pallets of all sizes.

[0026] As Figure 4As shown in the figure, the pallet handling mechanism 3 described in this patent is composed of a pallet handling base 301, a module mounting plate 302, a drag chain base plate 303, a drag chain 304, a linear module 305, a cylinder mounting seat 306, a vacuum gauge 307, a guide rod cylinder 308, a cylinder connecting plate 309, a suction cup mounting plate 310, and a vacuum suction cup 311.

The vacuum gauge 307 is used to monitor the vacuum state to ensure the normal operation of the suction cup.

[0027] As Figure 5 and Figure 6As shown in the figure, the battery loading and unloading handling mechanism 4 described in this patent includes a cylindrical base assembly 401, a loading Y-axis linear module 402, an unloading Y-axis linear module 403, a module connection linear guide rail 404, an X-axis linear module mounting vertical plate 405, a loading X-axis linear module 406, an unloading X-axis linear module 407, a module connection plate 408, a cylinder mounting plate 409, a Z-axis linear guide rail 410, a single-rod cylinder 411, a buffer 412, a slider connection vertical plate 413, a foot-mounted floating joint 414, a stop post 415, a rib plate 416, a rib plate connection plate 417, a buffer support 418, a buffer 419, a Y-axis linear guide rail 420, a slider connection plate 421, a slide rail stop piece 422, a Y-axis single guide post cylinder 423, a floating joint 424, an L-shaped connection plate 425, a rotary cylinder 426, a vacuum suction cup seat 427, a vacuum suction cup 428, a proximity sensor 429, and an adjustment distance stop block 430.The cylindrical base assembly 401 is installed on the equipment substrate 101. The loading Y-axis linear module 402, the unloading Y-axis linear module 403, the module connection linear guide 404, and the X-axis linear module mounting vertical plate 405 are installed on the cylindrical base assembly 401. The loading X-axis linear module 406 and the unloading X-axis linear module 407 are installed on the X-axis linear module mounting vertical plate 405. There are 2 module connection plates 408, which are respectively installed on the loading X-axis linear module 406 and the unloading X-axis linear module 407. The cylinder mounting plate 409 and the Z-axis linear guide 410 are installed on the module connection plate 408. The single-rod cylinder 411 and the buffer 412 are installed on the cylinder mounting plate 409. The slider connection vertical plate 413 is installed on the Z-axis linear guide 410. The foot-mounted floating joint 414 is installed on the slider connection vertical plate 413 and is connected to the single-rod cylinder 411. The stop post 415, the rib plate 416, the rib plate connection plate 417, the Y-axis single-guide post cylinder 423, and the distance adjustment stop block 430 are installed on the slider connection vertical plate 413. The buffer support 418, the Y-axis linear guide 420, the slide rail stop piece 422, and the Y-axis single-guide post cylinder 423 are installed on the rib plate connection plate 417. The buffer 419 is installed on the buffer support 418. The slider connection plate 421 and the L-shaped connection plate 425 are installed on the Y-axis linear guide 420. The floating joint 424 is connected to the Y-axis single-guide post cylinder 423 and the L-shaped connection plate 425. Two rotary cylinders 426 are respectively installed on the rib plate connection plate 417 and the slider connection plate 421. The vacuum suction cup seat 427 is installed on the rotary cylinder 426. The vacuum suction cup 428 and the proximity sensor 429 are installed on the vacuum suction cup seat 427.

[0028] For loading handling, the batteries in the tray are placed into the loading belt line of the X-RAY equipment. For unloading handling, the batteries on the unloading belt line of the X-RAY equipment are placed into the unloading tray. Each time, 2 batteries can be handled. By driving the L-shaped connection plate 425, the rotary cylinder 426, the vacuum suction cup seat 427, the vacuum suction cup 428, the proximity sensor 429, and the distance adjustment stop block 430 to move through the Y-axis single-guide post cylinder 423, the distance between the batteries can be switched, and it can be adapted to all trays with different battery spacings. The proximity sensor 429 can sense whether there is a battery in the tray. If there is no battery, it will not suck, avoiding the risk of dropping the entire tray with a battery when sucking. The rotary cylinder 426 can rotate the battery by 90°, so that it enters the X-RAY equipment in the correct direction.

[0029] Such as Figure 7As shown in the figure, the tray buffer mechanism 5 described in this patent is composed of a tray buffer base 501, fixed guide columns 502, sliding guide columns 509, a fixed bottom plate 503, a sliding bottom plate 510, linear bearings 504, left and right positioning seats 505, a backplane positioning seat 507, upper and lower limit photoelectric sensors 508, a temporary storage tray lifting plate 511, a micro electric push rod lifting motor 512, a sensor slide rail 513, a photoelectric sensor 514, and a battery tray 515. Among them, the base is the support foundation. The fixed guide columns and the sliding guide columns cooperate with the linear bearings to realize the lifting and guiding of the sliding bottom plate. The left and right positioning seats and the backplane positioning seat perform horizontal and vertical positioning of the tray. The micro electric push rod lifting motor drives the sliding bottom plate to drive the temporary storage tray lifting plate to rise and fall. The upper and lower limit photoelectric sensors and the photoelectric sensor monitor the position of the sliding bottom plate. The principle is that the empty tray after feeding is transferred to the buffer mechanism by the tray handling mechanism. After being positioned by the positioning seat, the electric push rod motor drives the sliding bottom plate to move downward to stack and store in sequence. When the empty tray is needed at the discharging end, the sliding bottom plate rises to the picking position, and the tray handling mechanism sucks the topmost empty tray and transfers it to the tray shaping and lifting mechanism 2 at the discharging end. The sensor monitors the position in real time to control the lifting range and reset, realizing the automatic storage and cyclic supply of the empty tray.

[0030] The upper and lower limit photoelectric sensor 508 monitors the position of the sliding bottom plate 510. When the preset stacking upper limit is reached, the mechanism stops receiving empty trays. [[ID=)4]]

[0031] When the tray shaping and lifting mechanism 2 at the discharging end needs an empty tray, the photoelectric sensor 514 detects that there is an empty tray in the buffer mechanism and triggers the micro electric push rod lifting motor 512 to start. The sliding bottom plate 510 moves upward to the origin position, and the tray handling mechanism 3 sucks the topmost empty tray and transfers it to the tray shaping and lifting mechanism 2 at the discharging end. For each empty tray taken out, the sliding bottom plate 510 automatically rises by the distance of the thickness of one tray, so that the upper empty trays are sequentially filled to the picking position until all the empty trays in the buffer mechanism are taken out, and the sliding bottom plate resets to the lower limit position.

[0032] As Figure 8As shown in the figure, the upper frame 6 described in this patent is composed of an aluminum profile 40×40 assembled frame 601, an upper frame door 602, a touch screen 603, buttons 604, and a three-color folding alarm light 605. Among them, the aluminum profile frame is the main support structure. The upper frame door can be opened and closed for equipment maintenance. The touch screen provides a human-machine interaction interface for setting parameters and monitoring the status. The buttons include start / stop, reset, emergency stop, etc. to achieve rapid control. The three-color folding alarm light uses red, yellow, and green colors and a buzzer to indicate the normal operation, warning, fault shutdown, and other states of the equipment. The principle is that the touch screen and buttons are connected to the programmable logic controller in the electrical wiring module to send instructions to drive the equipment to operate. The controller monitors the sensor signals and operating parameters in real time, controls the alarm light to feedback the status, the aluminum profile frame provides installation support for each component, and the upper frame door cooperates with the protection mechanism to ensure safety.

[0033] As Figure 9 shown in the figure, the protection frame 7 of this patent is composed of an aluminum profile frame 701, a single-opening door 702, and foot cups 703. Among them, the aluminum profile frame constitutes the main protection structure. The single-opening door is installed on the frame for personnel to enter and exit. The foot cups are used for the support and leveling of the frame. The principle is that the aluminum profile frame completely covers the original X-RAY equipment loading and unloading belt line 8 to form a closed protection area. When the single-opening door is opened, the equipment automatically stops, prohibiting employees from entering when operating in the dangerous area, thus protecting the safety of employees.

[0034] As Figure 10As shown in the figure, the original X-RAY equipment loading and unloading belt line 8 described in this patent mainly consists of the original X-RAY equipment 801, the original loading belt line 802, and the original unloading belt line 803. Each part works closely together to achieve the efficient transfer and detection of batteries in the X-RAY equipment. The original loading belt line 802 is responsible for accurately transporting the batteries from the external station to the detection area of the X-RAY equipment. Structurally, it includes main components such as a motor, a driving wheel, a driven wheel, and a conveyor belt. The motor, as the power source, is connected to the driving wheel through a belt or a chain, providing continuous and stable rotational power for the driving wheel. The driving wheel drives the conveyor belt to operate, and the conveyor belt is made of materials with certain flexibility and wear resistance, such as PVC or rubber, to ensure that the battery surface will not be scratched or damaged during the transportation of the battery. The driven wheel is installed at the other end of the conveyor belt, playing a role in tensioning and guiding, ensuring the smooth operation of the conveyor belt and avoiding slack or deviation. Above the conveyor belt, some auxiliary structures are usually set, such as a battery positioning device or a limit baffle. The battery positioning device can adopt the cooperation of a sensor and a mechanical structure. When the battery is placed on the conveyor belt, the sensor can quickly detect the position of the battery and fine-tune the position of the battery through the mechanical structure to ensure that the battery enters the detection station of the X-RAY equipment in the correct posture and position, improving the detection accuracy and stability. The original unloading belt line 803 is responsible for outputting the batteries that have completed the detection from the detection area of the X-RAY equipment to the subsequent processing station. Its structure is similar to that of the loading belt line, and it also has components such as a motor, a driving wheel, a driven wheel, and a conveyor belt. However, the unloading belt line may have some special designs according to the classification requirements after the battery detection. For example, a detection device is installed along the conveyor belt, which can automatically classify the batteries according to the detection results of the batteries. If a good-quality battery is detected, the conveyor belt will transport it to the good-quality collection area; if a defective battery is detected, the defective battery will be guided to the defective collection area through a specific diversion mechanism, such as a movable baffle or a steering device, realizing the efficient classification and processing of the batteries and improving the production efficiency and product quality control level.

[0035] Working principle: An employee manually places a stack of trays with batteries into the feeding-end tray shaping and lifting mechanism 2. In the battery loading and unloading handling mechanism 4, the feeding Y-axis linear module 402 and the feeding X-axis linear module 406 are driven by a servo motor. The vacuum suction cup 428 is moved above the tray. After sucking 2 batteries, the rotary cylinder 426 rotates the batteries by 90° and then moves them to the original feeding belt line 802 to place the batteries, completing the automatic feeding operation. After there are no batteries in the tray, the vacuum suction cup 311 in the tray handling mechanism 3 places the tray into the tray buffer mechanism 5. After the batteries in the original discharging belt line 803 are in place, the discharging Y-axis linear module 403 and the discharging X-axis linear module 407 in the battery loading and unloading handling mechanism 4 are driven by a servo motor. The vacuum suction cup 428 is used to suck the batteries in the original discharging belt line 803, rotate them by 90°, and then transport them to the discharging-end tray shaping and lifting mechanism 2. After the tray is full of batteries, the tray handling mechanism 3 transports the empty tray in the tray buffer mechanism 5 to the tray shaping and lifting mechanism 2, and the cycle continues.

[0036] For those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can also be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
