Description

Technical Field

[0001] This application relates to the field of battery cell production, and particularly to a double-station battery cell isolation glue printing device and its processing technology. Background Art

[0002] A battery cell is a semiconductor thin slice that converts solar energy into electrical energy, mainly divided into three types: monocrystalline silicon, polycrystalline silicon, and amorphous silicon, and is widely used in various solar power generation devices.

[0003] After the production of the battery cell is completed, an isolation glue needs to be applied to one side. The isolation glue is an electrical insulating material with good insulation, chemical resistance, high temperature resistance, and wear resistance. The isolation glue is mainly used to isolate the direct contact between battery cells, prevent internal short circuits of the battery, and at the same time, it can also provide a certain mechanical support and protection function to ensure the stability and safety of the battery during use.

[0004] After the battery cell is produced from the previous process, it is moved to the processing table of the printing device through a conveyor belt. At the feeding station, visual inspection is set above the processing table. When the battery cell moves to the processing table, the visual inspection can detect the feeding situation and at the same time detect the position of the battery cell. Subsequently, the processing table rotates to the printing station and is printed through the printing module. After that, the processing table rotates to the discharging station. After the printing effect is detected through visual inspection, it is transported out of the processing table through the discharging device.

[0005] However, during the rotation of the battery cell with the processing table, the position of the battery cell is prone to shift, which easily affects the printing effect of the printing module. When detecting the printing effect at the discharging station, unqualified battery cells need to be reprinted, affecting the processing efficiency. Summary of the Invention

[0006] In order to improve the processing efficiency, this application provides a double-station battery cell isolation glue printing device and its processing technology.

[0007] In a first aspect, this application provides a double-station battery cell isolation glue printing device, adopting the following technical solution: A double-station battery cell isolation glue printing device, comprising a processing table, a driving assembly, a fixing assembly and a control assembly. The processing table includes a turntable, and the turntable is provided with an avoidance opening and a processing opening. The avoidance opening is arranged on one side of the processing opening close to the axis of the turntable. The fixing assembly includes a breathable belt and a suction attachment. The avoidance opening is used for the breathable belt to pass through. The breathable belt is arranged on the outer periphery of the processing opening. The suction attachment includes a connecting plate and an elastic membrane. The connecting plate is arranged on the inner periphery of the breathable belt. An air flow groove is provided at the upper end of the connecting plate, and an air extraction port is provided at the bottom of the air flow groove. The edge of the elastic membrane is fixedly connected to the lower end of the connecting plate, and the elastic membrane covers the air extraction port. The driving assembly includes a conveying roller, and the conveying roller is arranged on the inner periphery of the breathable belt. The control assembly includes a fixing ring, a bearing, a spring, a pull rope, a switch and an alarm. The fixing ring is coaxially and fixedly connected to the outer wall of the conveying roller. The bearing is slidably connected to the outer wall of the conveying roller. One end of the spring is fixedly connected to the fixing ring, and the other end of the spring is fixedly connected to the inner ring of the bearing. One end of the pull rope is fixedly connected to the lower end of the elastic membrane, and the other end of the pull rope is fixedly connected to the outer ring of the bearing. The switch is arranged on the side of the bearing away from the fixing ring, and the switch is used for the bearing to abut against. The switch is electrically connected to the alarm.

[0008] By adopting the above technical solution, when the battery cell moves onto the breathable belt, the suction attachment adsorbs the battery cell to realize the fixation of the battery cell, reducing the probability of the battery cell shifting in position during the rotation of the turntable, reducing rework and improving the processing efficiency. The pull rope is slackened, reducing the friction of the movement of the breathable belt. The pull rope pulls down the elastic membrane to reduce the pressure at the adsorption opening and fix the battery cell. When the battery cell has a large deviation, the battery cell does not completely cover the adsorption opening, there is no pressure difference inside and outside the elastic membrane, the bearing slides to abut against the switch, and the switch gives an alarm to remind the operator to adjust the position of the battery cell.

The centrifugal force causes the first hinge rod and the second hinge rod to expand outward against the spring force, and the bearing approaches the fixing ring to make the pull rope slack, reducing the friction of the movement of the breathable belt. When the battery cell moves to the correct position, the conveying roller stops rotating, and the spring force causes the bearing to move away from the fixing ring, and the pull rope pulls down the elastic membrane to reduce the pressure at the adsorption opening and fix the battery cell.

[0013] Preferably, the driving assembly includes a first support roller and a second support roller. The first support roller is disposed between the avoidance opening and the processing opening, and the second support roller is disposed on the side of the processing opening away from the axis of the turntable. Both the first support roller and the second support roller are connected to the upper end of the turntable, and the upper ends of the first support roller and the second support roller are flush with the upper end of the adsorption plate. The outer walls of the first support roller and the second support roller are both used to abut against the air-permeable belt.

[0014] By adopting the above technical solution, the first support roller and the second support roller support the air-permeable belt. The first support roller and the second support roller reduce the friction of the air-permeable belt during movement and extend the service life of the air-permeable belt.

[0015] Preferably, the driving assembly further includes a driving roller, a conveying roller, and a conveying member. The driving roller is used to control the movement of the air-permeable belt, the outer wall of the driving roller abuts against the air-permeable belt, and the driving roller is connected to the conveying roller through the conveying member.

[0016] By adopting the above technical solution, the driving roller rotates to drive the air-permeable belt to move, facilitating the loading and unloading of the battery wafers and being convenient for the user to use.

[0017] Preferably, the processing table further includes a fixing frame fixedly connected to the lower end of the turntable. There are a plurality of fixing frames, and fixing frames are provided on both sides of the processing opening.

Around the axis of the turntable, a feeding station, a printing station, a qualified product discharging station and a defective product discharging station are sequentially and evenly spaced on the turntable. The detection component is arranged above the qualified product discharging station. The feeding component is used to feed the feeding station, the printing module is used to process the battery cells at the printing station, the detection component is used to detect the printing quality, and according to the detection result, the battery cells are discharged from the qualified product discharging station or the defective product discharging station.

[0020] By adopting the above technical solution, the processed battery cells are respectively discharged from the qualified product discharging station and the defective product discharging station, reducing the impact on the previous production line of printing and enabling the processing production line to operate stably.

The centrifugal force causes the first hinge rod and the second hinge rod to expand outward against the spring force. The bearing approaches the fixed ring, causing the pull rope to slacken and reducing the friction of the air-permeable belt moving. When the battery cell moves to the correct position, the conveying roller stops rotating, and the spring force causes the bearing to move away from the fixed ring. The pull rope pulls down the elastic membrane to reduce the pressure at the adsorption port and fix the battery cell; When the conveying roller stops rotating, the spring tends to recover its deformation. The elastic force of the spring drives the pulling rope to pull downwards. The deformation of the elastic membrane also needs to overcome the pressure difference between the inside and outside of the elastic membrane. The bearing cannot abut against the switch. When the battery chip has a large deviation, the battery chip does not completely cover the adsorption port, there is no pressure difference between the inside and outside of the elastic membrane, the bearing slides to abut against the switch, and the switch issues an alarm to remind the operator to adjust the position of the battery chip.
