Description

Technical Field

[0002] In the production process of square lithium batteries, both formation and capacity division are very important. Through formation, the activity of the battery can be activated to ensure the performance and life of the battery, and capacity division can reduce the short board effect after the battery combination. At present, the battery formation and capacity division equipment mechanism uses multiple sets of probe modules to test the square batteries in the tray. In order to maximize the use of the equipment, batteries of different models and sizes are usually used. This requires adjusting the distance between the probe modules to ensure the compatibility of the equipment. When the probe module and other components are damaged and need to be repaired, in order not to affect the utilization rate of the equipment, the probe module needs to be removed from the equipment and replaced with a new spare module to meet continuous production.

When the distance between each independent module is adjusted by the slider, there are a large number of connecting cables at the rear of the module, which is difficult to operate and the cables are too heavy and too many, resulting in unstable connection.

[0084] The bottom frame mechanism 2 is first composed of a bottom frame body 210 and a bottom frame 210 connector to form a bottom frame body, and then guide columns 211, support columns 212, primary positioning sensors, fixed pallet support guides 213 and adjustable pallet support guides 214 are installed thereon, and then the pick-up and delivery sensors 215 and position detection sensors 216 are respectively installed on the support columns 212; when the external equipment of the pallet material frame 5 picks up and delivers the pallet material frame 5 and passes through the pick-up and delivery sensor 215 area, the equipment enters an interlocking and prohibited action state, which solves the problem of batteries and related structural parts being crushed due to misoperation of the pick-up and delivery equipment; a combination of a fixed pallet support guide 213 on one side and an adjustable pallet support guide 214 on the other side is adopted, which reduces the difficulty of equipment manufacturing and also solves the inconsistency problem caused by errors during mass manufacturing and assembly of the equipment; after the pallet material frame 5 enters the equipment, it is placed in the specified position after being guided left and right, and a group of sensors diagonally opposite can detect whether the pallet is placed flat.

[0085] The lifting and positioning mechanism 4 includes: a lifting frame 410, a linear bearing 412 and a heat dissipation assembly 411; the linear bearing 412 is connected to the lifting frame 410, and the linear bearing 412 is sleeved on the guide column 211, and the lifting frame 410 has a hollow portion, and the hollow portion reveals the tray support guide; the heat dissipation assembly 411 is detachably connected to the lifting frame 410.

[0086] The lifting and positioning mechanism 4 also includes a front tray guide plate 413, a rear tray limit guide plate 414 and a positioning pin 415; the front tray guide plate 413 and the rear tray limit guide plate 414 are respectively arranged at the front and rear ends of the lifting frame 410; the positioning pin 415 is connected to the lifting frame 410, and the positioning pin 415 is diagonally arranged.

[0087] The lifting and positioning mechanism 4 is composed of a lifting frame 410 which is formed in one process as the main body. The floating joint connector, power supply assembly, limit buffer block, secondary positioning sensing assembly, positioning pin 415, heat dissipation assembly 411, press-down buckle, front guide plate 413 of the tray, proximity sensing sheet, rear limit guide plate 414 of the tray, and linear bearing 412 are all installed on the lifting frame 410. Secondly, the reflective sticker pasting plate is fixed on the front guide plate 413 of the tray; finally, the reflective sticker is pasted on the reflective sticker pasting plate.

[0088] The lifting and positioning mechanism 4 uses a lifting frame 410 that is formed once as the main body, which can better ensure the position accuracy of the positioning pin 415 and the guide position; a reflective sticker is set on the front side, and before the external device sends the pallet material frame 5 into the device, the sensor carried by the external device re-tests whether the lifting and positioning mechanism 4 is in a normal state, and then sends it into the device after re-testing and confirmation, which can further solve the problem of malfunction of the delivery device causing the battery and related structural parts to be crushed; the pallet material frame 5 has completed one positioning in the left and right directions before the lifting and positioning mechanism 4 moves, and the lifting and positioning mechanism 4 moves upward During the process, the front guide plate 413 and the rear limit guide plate 414 of the tray complete the first positioning in the front and rear directions, and then the two diagonal positioning pins 415 complete the secondary positioning and asymmetric anti-reverse detection; the front side of the heat dissipation component 411 is fixed with a downward buckle, so that the fan component can be pulled out from the back for maintenance without stopping the entire line, thereby improving the efficiency of the entire line; the fan of the heat dissipation component 411 is arranged directly below the tray material frame 5, and is evenly arranged corresponding to the battery. The battery can be cooled during the charging and discharging process, so that the battery charging and discharging uniformity is better, and the capacity difference caused by the battery temperature difference is avoided. At the same time, a line cover is set at the wiring position to effectively prevent the cooling fan cable from being corroded by the electrolyte.

[0089] The tray material frame 5 is composed of a tray bottom frame 210, a tray side plate, a tray end plate, a tray liner, and a battery pad. The tray bottom frame 210 is provided with an asymmetric positioning pin hole, which can realize the relative positioning and anti-reverse function of the battery in the device. The tray material frame 5 is made of high temperature and corrosion resistant insulating materials, and is connected with stainless steel fasteners to effectively avoid the influence of high temperature and electrolyte in the formation process; the battery is limited by a simple combination of liner and pad. When the battery changes in a single size, only one type of simple parts needs to be replaced to achieve flexible production, solving the high cost problem of high-flexibility production line trays.

[0090] The equipment provided by the present invention is used for negative pressure formation, capacity division, load adjustment and other processes of square batteries. When the equipment is running, the external equipment sends the tray material frame 5 (battery carrier) into the tray positioning mechanism for positioning, confirms that the tray material frame 5 is accurately positioned once in the bottom frame mechanism 2, and the power mechanism 320 drives the lifting and positioning mechanism 4 to move upward and positions the tray material frame 5 once front and back. The lifting and positioning mechanism 4 continues to move upward, and uses the asymmetric positioning pin 415 to perform secondary positioning and anti-reverse detection on the tray material frame 5. After the secondary positioning is successful, it continues to be lifted upward until the probe, suction nozzle and other components in the integrated probe module 1 contact the battery, and then the battery process flow is carried out. After the process is completed, the power mechanism 320 reverses to reset the equipment, and the external equipment takes out the tray material frame 5 to the next process. If the secondary positioning fails, the power mechanism 320 reverses to reset the equipment, and the external equipment takes out the tray material frame 5 to the manual processing position.

[0091] Firstly, through the stepless adjustment of each mechanism and the convenient pull-out design of the module, the flexible production capability of the equipment is enhanced, and the relatively difficult maintenance and replacement problems of traditional equipment are solved; at the same time, through the integration of the power module and the probe module 1, the power loss of the high-power cables of the equipment is reduced, and the charging and discharging efficiency of the equipment is improved.

[0092] The equipment consists of an integrated probe module 1, a bottom frame mechanism 2, a top frame mechanism 3, a lifting and positioning mechanism 4, a pallet material frame 5, and a fire sprinkler pipe. The bottom frame mechanism 2 and the top frame mechanism 3 constitute the main body of the equipment. The integrated probe module 1 slides, positions, fastens and locks on the top frame mechanism 3. The lifting and positioning mechanism 4 is driven by the power mechanism 320 in the top frame mechanism 3 to drive the pallet material frame 5 to move up and down. The equipment parts for the three processes applicable to the equipment can be highly unified and can be flexibly used alternately between different processes, which greatly reduces the equipment repair and maintenance costs for enterprises.
