[0021] The specific implementation of the technical solution of the utility model is further described below through examples and in conjunction with the accompanying drawings.

[0022] The utility model provides an automatic glue cleaning mechanism for the surface of a soft-pack lithium battery, the mechanism comprising a main body 1, the main body 1 being arranged at one side of a glue spraying head 10, the main body 1 being provided with a cleaning component, the cleaning component cleaning the glue spraying head 10 through a non-woven fabric, avoiding the phenomenon of glue clogging the glue spraying head 10, improving production efficiency, and reducing labor costs caused by manual cleaning.

[0023] Reference Figure 1 The figure shows an appearance schematic diagram of the automatic glue cleaning mechanism on the surface of a soft-pack lithium battery provided in an embodiment of the utility model. As shown in the figure, the utility model includes a main body 1 for supporting and placing other components. The main body 1 includes a pair of fixed plates, and the shape of the fixed plates is L-shaped. The two fixed plates are connected and fixed by a number of connectors. A number of fixing holes are provided on the fixed plate for fixing the components connected to the main body 1. Symmetrical components are provided on the two fixed plates to meet the work of two groups of equipment at the same time. The main body 1 is provided with a glue spraying head 10 for spraying glue on the product. The glue spraying head 10 is connected to a servo motor 9, and the servo motor 9 is used to control the movement of the glue spraying head 10. When the glue spraying head 10 is in the working position, the product located at the glue spraying station is sprayed with glue; after the glue spraying is completed, the servo motor 9 controls the glue spraying head 10 to move to the cleaning position.

[0024] The main body 1 is provided with a cleaning component for cleaning the glue spray head 10. The cleaning component includes a discharge tray 2 and a receiving tray 3. The discharge tray 2 is arranged at the top of the main body 1 close to the glue spray head 10, and the receiving tray 3 is arranged at the bottom of the glue spray head 10. The discharge tray 2 and the receiving tray 3 are both circular, and the specific shape is that the two discs are connected by a central rotating shaft, wherein the diameter of the discharge tray 2 is larger than the diameter of the receiving tray 3, and the distance between the two discs is the same. Non-woven fabrics are wound around the discharge tray 2 and the receiving tray 3, and the winding directions are opposite. The two are connected by non-woven fabrics, and the distance between the discs is the width of the non-woven fabrics. The non-woven fabrics are used to clean the glue spray head 10, and the glue remaining on the glue spray head 10 after the glue spraying work is completed is removed by wiping. The material discharging tray 2 and the material receiving tray 3 are both controlled by the servo motor 9. After the glue spray head 10 is cleaned, the non-woven fabric required for cleaning the glue spray head 10 is released by rotation, ensuring that the non-woven fabric part contacted by the glue spray head 10 is clean and has no glue attached when cleaning the glue spray head 10. The used non-woven fabric is collected by the receiving tray 3 through the rotation of the receiving tray 3 to prevent affecting the operation of the cleaning mechanism.

[0025] The advantage of this design is that the mechanism can automatically clean the glue spray head without manual intervention. The servo motor controls the movement of the discharge tray and the receiving tray to make the cleaning non-woven fabric contact the glue spray head and wipe off the residual glue. This can improve work efficiency and reduce the time and workload of manual cleaning. Since non-woven fabric is used as a cleaning material, it can be reused, and by adjusting the movement of the discharge tray and the receiving tray, it is ensured that the non-woven fabric part that the cleaning glue spray head contacts is clean and has no glue attached. This effectively saves the amount of cleaning materials used and saves costs. Through the automatic cleaning mechanism, it can be ensured that the effect of each glue spray head cleaning is consistent and reliable. The wiping action of the non-woven fabric can effectively remove glue residues, keep the glue spray head clean, and avoid glue clogging or affecting the quality of glue spraying. A plurality of working positions are provided on the main body 1, and the design of the fixed plate makes it possible to meet the working requirements of two sets of equipment at the same time. This can improve production efficiency, save space, and make the entire workflow more compact and efficient.

[0026] The main body 1 is provided with a plurality of guide wheels 6. In this embodiment, there are 7 guide wheels 6 on a single fixed plate, which are respectively in contact with different surfaces of the non-woven fabric, and are used to change the direction of movement of the non-woven fabric, and guide the non-woven fabric connected between the discharge tray 2 and the receiving tray 3 to other parts of the fixed plate of the main body 1. The non-woven fabric between the discharge tray 2 and the guide wheels 6, between different guide wheels 6, and between the guide wheels 6 and the receiving tray 3 are all in a tightened state, so that the rotation speeds of the discharge tray 2, the guide wheels 6, and the receiving tray 3 are consistent, and are the same as the speed of movement of the non-woven fabric. The non-woven fabric in a tightened state can be in close contact with the glue spray head 10 located in the cleaning position, thereby increasing its cleaning effect.

[0027] A grating wheel 7 is connected to the back of the fixed plate corresponding to any one of the guide wheels 6. The grating wheel 7 is located inside the main body 1, between the two fixed plates. The grating wheel 7 rotates synchronously with the guide wheel 6. When it rotates one circle, it triggers the slot-type photoelectric sensor 4 provided at the grating wheel 7, so that the distance of rotation of the grating wheel 7 can be measured. The distance is the same as the distance of rotation of the guide wheel 6. By measuring the distance, the moving distance of the non-woven fabric can be specifically measured and controlled. The grating wheel 7 can also be used to calculate the amount of non-woven fabric remaining in the discharge tray 2, providing a data basis for the subsequent replacement of the non-woven fabric, and avoiding the non-woven fabric from running out during the glue spraying process and causing it to fail to work normally.

[0028] A sensor 4 is also provided on the main body 1. The sensor 4 is provided on one side of the glue spray head 10, at the same level as the glue spray head 10, and is provided toward the position where the glue spray head 10 contacts the non-woven fabric when the glue spray head 10 is in the cleaning position. The sensor 4 is used to detect whether the glue spray head 10 contacts the non-woven fabric, and to send a control signal to the clamping block 5 provided on the main body 1. The sensor 4 is divided into two parts, wherein the position corresponding to the first part is the position of the non-woven fabric when the glue spray head 10 is in the working position. When the first part sensor 4 receives a signal, the glue spray head 10 does not contact the non-woven fabric, and no signal is required at this time; the second part sensor 4 is at the same level as the first part sensor 4, and is farther away from the glue spray head 10 than the first part sensor 4. Its corresponding position is the position of the non-woven fabric when the glue spray head 10 is in the cleaning position. At this time, due to the contact between the glue spray head 10 and the non-woven fabric, the non-woven fabric is slightly moved from its original position. When the second part sensor 4 receives a signal, the glue spray head 10 contacts the non-woven fabric, and a signal is sent to the clamping block 5 at this time.

[0029] The advantage of this design is that the moving direction of the non-woven fabric can be effectively changed through the guide wheel 6, and the non-woven fabric connected between the discharge tray 2 and the receiving tray 3 can be guided to other parts of the fixed plate of the main body 1. This ensures that the non-woven fabric is in close contact with the cleaning position of the glue spray head 10, thereby increasing the cleaning effect. The grating wheel 7 rotates synchronously with the guide wheel 6 and is triggered by the slot-type photoelectric sensor 4, which can accurately measure the moving distance of the non-woven fabric. This measurement information can be used to accurately control the movement of the non-woven fabric and provide a data basis for replacing the non-woven fabric to avoid work interruption caused by the exhaustion of the non-woven fabric during the glue spraying process. The sensor 4 is used to detect whether the glue spray head 10 is in contact with the non-woven fabric and send a control signal to the clamping block 5. This ensures that when the glue spray head 10 is in the cleaning position, the sensor detects the contact with the non-woven fabric, thereby triggering a signal to ensure the normal operation of the cleaning mechanism.

[0030] The main body 1 is provided with a clamping block 5, which includes a fixed part and a moving part. The fixed part and the moving part are respectively arranged on the two sides of the non-woven fabric, wherein the fixed part is arranged on the side of the non-woven fabric close to the glue spraying head 10, and the moving part is arranged on the side of the non-woven fabric away from the glue spraying head 10. The moving part includes a slide rail connecting part and a slider. The vertical part of the slider connecting part is connected to the main body 1, and its horizontal part extends outward from the main body 1. The bottom surface of the horizontal part of the slider connecting part is provided with a slide rail. The direction of the slide rail is parallel to the main board, and its extension direction passes through the fixed part of the clamping block 5. The slide rail is connected to the slider below, and the slider can move along the slide rail. The movement of the slider is controlled by the sensor 4. When the sensor 4 senses that the glue spraying head 10 is in contact with the non-woven fabric, the slider is controlled to move to a position in contact with the fixed part, which is used to clamp the non-woven fabric to prevent it from moving. The side of the slider facing the fixed part is provided with a rounded corner, and the side of the fixed part facing the moving part is also provided with a rounded corner, so that the non-woven fabric will not be broken when the two are in contact.

[0031] The main body 1 is also provided with a spring pad 8, which is arranged vertically upward and contacts the non-woven fabric that is changed to the horizontal direction by the guide wheel 6. The top surface of the spring pad 8 is in close contact with the bottom surface of the non-woven fabric, and the non-woven fabric is also in contact with the glue spray head 10. The top surface of the spring pad 8 is provided with a cleaning part that can absorb and store glue, and the cleaning part is in contact with the non-woven fabric. After the non-woven fabric cleans the glue spray head 10, more glue will be attached to the non-woven fabric. When the part of the non-woven fabric that is stained with glue passes through the spring pad 8, the side with glue attached contacts with the spring pad 8. The spring pad 8 can clean the glue on the non-woven fabric, reduce the amount of glue residue on the non-woven fabric, and improve the reusability of the non-woven fabric.

[0032] During the use of the utility model, the mechanism is first installed and powered on to carry out the glue spraying process, and the material is transferred to the glue spraying station through the tray to prepare the battery core glue spraying or foam glue spraying. After the RFID senses the tray, the tray is lifted up to start the automatic glue spraying process, and the glue is atomized and sprayed on the battery core of the product being processed. After the glue spraying is completed, the processed product is output, and the glue spraying head 10 is driven to rotate to the cleaning position by the connected servo motor 9. At this time, the glue spraying head 10 is in close contact with the non-woven fabric. After the sensor 4 provided on the main body 1 detects that the glue spraying head 10 has contacted the non-woven fabric, the sensor 4 sends the signal of the glue spraying head 10 in place to the PLC trigger program to control the motor to rotate through the servo driver, thereby driving the receiving tray 3 to rotate. When the receiving tray 3 rotates, it drives the non-woven fabric wrapped on the receiving tray 3 to move, and at the same time, the non-woven fabric movement data can be output by the grating wheel 7, and the non-woven fabric stops after moving a suitable distance. At this time, the sensor 4 sends a signal to the clamping block 5. After receiving the signal, the clamping block 5 controls the slider to move to contact with the fixed part, and the two clamp the non-woven fabric tightly. At this time, the glue spray head 10 contacts the clean non-woven fabric, and the servo motor 9 drives the glue spray head 10 to move back and forth in a small range. The direction of the forward and backward movement is perpendicular to the movement direction of the non-woven fabric. Through the relative movement between the non-woven fabric in close contact, the glue remaining on the glue spray head 10 after the glue spraying is completed can be cleaned by the non-woven fabric, and due to the fixing effect of the clamping block 5, the non-woven fabric will not be driven with the movement of the glue spray head 10. After cleaning, the glue spray head 10 returns to the working position through the servo motor 9 for the next cycle. During use, the spring pad 8 can clean the non-woven fabric to a certain extent.

[0033] The advantage of this design is that the clamping block 5 can accurately clamp the non-woven fabric, ensuring that the non-woven fabric will not move during the glue spraying process, and ensuring the accuracy and consistency of the glue spraying. The slider and the fixed part on the main body 1 are both provided with rounded corners to ensure that the non-woven fabric will not break when the slider contacts the fixed part, thereby improving the reliability and service life of the equipment. The top surface of the spring pad 8 is provided with a cleaning part that can absorb and store glue. When the non-woven fabric passes through the spring pad, the cleaning part can clean the glue on the non-woven fabric, reduce the residual amount of glue, and improve the reusability of the non-woven fabric. The sensor 4 senses the contact between the glue spray head 10 and the non-woven fabric and controls the movement of the slider. The PLC trigger program controls the rotation of the motor through the servo driver to realize automatic alignment and control of the glue spray head and the non-woven fabric, thereby improving work efficiency and production quality. This design is suitable for application scenarios such as battery core glue spraying or foam glue spraying, and can be flexibly applied to different product processing requirements.

[0034] In summary, the utility model provides an automatic glue cleaning mechanism for the surface of a soft-pack lithium battery. The mechanism is arranged on one side of a glue spray head 10, and a cleaning component is arranged inside. The cleaning component includes a non-woven fabric, which is wound around a material discharge tray 2 and a material receiving tray 3, and changes the moving direction through a guide wheel 6, and is in a tightened state. A sensor 4 is arranged in the mechanism to determine whether the glue spray head 10 is in place, and controls the rotation of the material receiving tray 3 and a clamping block 5 to clamp the non-woven fabric during cleaning, and control the relative movement between the nozzle and the non-woven fabric, so as to clean the residual glue on the glue spray head 10 through the non-woven fabric. The utility model solves the problem in the prior art that residual glue on the glue spray head 10 is prone to cause blockage, resulting in downtime of the production line, and lacks equipment for effectively cleaning the glue spray head 10, thereby improving the production efficiency of the product and reducing labor costs.
