Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, specifically to a coating equipment and a battery production line. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Currently, traditional two-component coating equipment is usually equipped with a proportioning head. Before using the coating equipment, it is necessary to check whether the proportion of the two-component mixed adhesive meets the coating process requirements. The conventional testing method is to manually disassemble the equipment and replace parts such as the proportioning head. Moreover, the disassembled parts such as the proportioning head are all disposed of as scrap. This is not only cumbersome and affects battery production efficiency, but also directly leads to increased production costs. Summary of the Invention

[0004] The purpose of this application is to provide a coating equipment and battery production line to improve the convenience of coating ratio detection, increase production efficiency, and reduce production costs. This objective is achieved through the following technical solution: In a first aspect, this application provides an adhesive application device, comprising: an adhesive mixing device, the adhesive mixing device comprising: a first dispensing assembly, including a first adhesive storage tank, a first adhesive hose, a first pumping component, a first single-component valve, and a first dispensing nozzle, wherein the first adhesive storage tank is used to store a first adhesive, one end of the first adhesive hose is connected to the first adhesive storage tank, the first pumping component is disposed on the first adhesive hose, the first single-component valve is connected to the other end of the first adhesive hose, and the first dispensing nozzle is connected to the first single-component valve; and a second dispensing assembly, including a second adhesive storage tank, a second adhesive hose, a second pumping component, a second single-component valve, and a second dispensing nozzle. The device includes a nozzle, a second glue storage tank for storing a second glue, one end of a second glue tube connected to the second glue storage tank, a second pumping component located on the second glue tube, a second single-component valve connected to the second glue tube, and a second dispensing nozzle connected to the second single-component valve; a mixing assembly including a two-component mixing valve and a mixing tube, the two-component mixing valve having two inlet ends connected to the other ends of the first glue tube and the second glue tube respectively, and one end of the mixing tube connected to the outlet end of the two-component mixing valve; and a dispensing head connected to the other end of the mixing tube.

[0005] According to the adhesive application equipment provided in this application, by connecting one end of a first adhesive hose to a first adhesive storage tank and providing a first single-component valve connected to the other end of the first adhesive hose, when the first pumping component on the first adhesive hose is activated and the first single-component valve is opened, the first adhesive can flow out from the first dispensing nozzle connected to the first single-component valve. Furthermore, by connecting one end of a second adhesive hose to a second adhesive storage tank and providing a second single-component valve connected to the other end of the second adhesive hose, when the second pumping component on the second adhesive hose is activated and the first single-component valve is opened, the second adhesive can flow out from the second dispensing nozzle connected to the second single-component valve. In addition, the first and second adhesive hoses are connected to a mixing hose via a two-component mixing valve. In this way, when it is necessary to calculate the glue ratio when the first and second colloids are mixed, the glue dispensing amounts of the first and second colloids are weighed within the same preset dispensing time, and the glue ratio of the first and second colloids is calculated by calculating the weight ratio of the first and second colloids. This ratio can then be compared with a preset glue ratio to complete the glue ratio verification. The entire process does not require disassembling the glue application equipment or replacing parts, thus reducing material waste and increased production costs caused by disassembling parts and disposing of them as scrap. Glue can be dispensed at any time to test and verify the glue ratio, improving the efficiency of glue ratio measurement and calculation. Repeated testing and verification can be performed. If the calculated glue ratio is within the preset range, it indicates that the glue ratio meets the requirements. At this point, the two-component mixing valve connected to the first and second glue tubes is opened to mix the first and second colloids, which are then applied to the workpiece through the mixing tube and the glue application head, thereby improving the glue application quality.

[0008] In some embodiments of this application, the adhesive application equipment further includes an adhesive ratio detection device. The adhesive ratio detection device includes a support assembly, a first weighing member, a second weighing member, a first adhesive receiving cup, and a second adhesive receiving cup. The support assembly is provided with a first protective member and a second protective member.

The second protective member is provided with a second protective groove for accommodating the second adhesive receiving cup. The first weighing member is located at the bottom of the first protective member and is used to weigh the weight of the first adhesive in the first adhesive receiving cup. The second weighing member is located at the bottom of the second protective member and is used to weigh the weight of the second adhesive in the second adhesive receiving cup.

[0009] In the above technical solution, the first receiving cup can be placed in the first protective groove of the first protective member. The first protective member serves a protective function to improve the stability of the first receiving cup. After the first dispensing nozzle of the adhesive applicator injects the first adhesive into the first receiving cup, the first weighing member can be used to weigh the first receiving cup to calculate the weight of the first adhesive in the first receiving cup. Similarly, the second receiving cup can be placed in the second protective groove of the second protective member. The second protective member serves a protective function to improve the stability of the second receiving cup. After the second dispensing nozzle of the adhesive applicator injects the second adhesive into the second receiving cup, the second weighing member can be used to weigh the second receiving cup to calculate the weight of the second adhesive in the second receiving cup. Therefore, the adhesive ratio when the first and second adhesives are mixed can be calculated from the weights of the first and second adhesives.

[0013] In the above technical solution, by setting a support base plate on the top of the support column, the first weighing component and the second weighing component are placed on the support base plate, thereby enabling the weighing of the first and second glue-receiving cups under stable support. The fixed frame of the drawer assembly is fixedly connected to the support base plate. When the drawer liner is pushed and pulled, it can slide relative to the fixed frame, so that the drawer liner can be located in a preset position within the accommodating space defined by the fixed frame. The first and second protective components are located inside the drawer liner. By opening a first opening and a second opening in the drawer liner that correspond to and communicate with the first and second protective grooves, the first glue-receiving cup can contact the first weighing component through the first opening when placed in the first protective groove, and the second glue-receiving cup can contact the second weighing component through the second opening when placed in the second protective groove, thereby enabling the weighing of the first and second glue-receiving cups.

[0014] In some embodiments of this application, the drawer assembly further includes a proximity sensor disposed on one side of the fixing frame along a first direction, for detecting the distance between the side of the fixing frame along the first direction and the drawer liner, the first direction being the sliding direction of the drawer liner.

[0015] In the above technical solution, by setting a proximity sensor on one side of the fixed frame along the first direction, when the drawer liner slides relative to the fixed frame along the first direction, the proximity sensor can detect the distance between the drawer liner and one side of the fixed frame along the first direction, so as to facilitate timely stopping the sliding when the drawer liner slides close to the side of the fixed frame along the first direction and reaches a preset distance.

[0016] In some embodiments of this application, the glue ratio detection device further includes a first position sensor and a second position sensor disposed on the drawer assembly, wherein the first position sensor is used to detect the position of the first glue receiving cup and the second position sensor is used to detect the position of the second glue receiving cup.

[0017] In the above technical solution, by setting a first position sensor and a second position sensor on the drawer assembly, the first position sensor is used to detect whether the first adhesive cup is placed in the first protective groove, and the second position sensor is used to detect whether the second adhesive cup is placed in the second protective groove, so that when the first adhesive cup is detected to be in the first protective groove, the first adhesive is injected into the first adhesive cup. Similarly, when the second adhesive cup is detected to be in the second protective groove, the second adhesive is injected into the second adhesive cup.

[0018] In some embodiments of this application, the glue ratio detection device further includes: a first lifting mechanism disposed within the drawer liner, the first lifting mechanism including a first clamping member and a first lifting drive member connected to the first clamping member, the first clamping member being used to clamp the first glue-receiving cup, and the first lifting drive member being used to drive the first clamping member to rise or fall, thereby causing the first glue-receiving cup to rise or fall; and a second lifting mechanism disposed within the drawer liner, the second lifting mechanism including a second clamping member and a second lifting drive member connected to the second clamping member, the second clamping member being used to clamp the second glue-receiving cup, and the second lifting drive member being used to drive the second clamping member to rise or fall, thereby causing the second glue-receiving cup to rise or fall.

[0019] In the above technical solution, when the first adhesive-receiving cup is placed in the first protective groove, it can be held by the first clamping member. Then, the first lifting drive member moves the first clamping member closer to the first weighing member until the first adhesive-receiving cup is placed on the first weighing member, thereby enabling the first adhesive-receiving cup to be weighed using the first weighing member. Similarly, when the second adhesive-receiving cup is placed in the second protective groove, it can be held by the second clamping member. Then, the second lifting drive member moves the second clamping member closer to the second weighing member until the second adhesive-receiving cup is placed on the second weighing member, thereby enabling the second adhesive-receiving cup to be weighed using the second weighing member.

[0020] In some embodiments of this application, the glue ratio detection device further includes a third weighing member and at least one third glue receiving cup. The inner liner of the drawer is also provided with a third protective member. The third protective member is provided with at least one third protective groove. The inner liner of the drawer has at least one third opening. The third opening corresponds to and communicates with the third protective groove. The third protective groove is used to accommodate the third glue receiving cup. The third weighing member is disposed in the installation space and is provided corresponding to the third opening. It is used to weigh the weight of the mixed glue in the third glue receiving cup.

[0021] In the above technical solution, by setting a third protective component inside the drawer liner, the third protective component has at least one third protective groove, and the drawer liner has at least one third protective groove corresponding to a third opening. When the third adhesive cup is placed in the third protective groove, it can contact the third weighing component below the drawer liner through the third opening. This allows the third weighing component to weigh the mixed adhesive in the third adhesive cup. This facilitates comparison between the measured weight of the mixed adhesive in the third adhesive cup and the preset weight value of the mixed adhesive (the preset sum of the weight values ​​of the first and second adhesives) to determine whether there is any deviation or abnormality in the weight value of the final mixed adhesive after the two-component adhesive ratio meets the requirements. This allows operators to detect the deviation in a timely manner and maintain and adjust the adhesive application equipment accordingly.

[0022] In some embodiments of this application, the glue ratio detection device further includes at least one third position sensor, which is disposed inside the drawer liner and is used to detect the position of the third glue receiving cup.

[0023] By installing at least one third position sensor in the drawer liner, the number of third position sensors being the same as the number of third adhesive cups, the third position sensors can be used to detect whether the third adhesive cup has been placed in the third protective groove of the protective component. Then, when the third adhesive cup is placed in the third protective groove, the adhesive applicator head of the adhesive mixing device can inject mixed adhesive into the third adhesive cup.

[0024] In some embodiments of this application, the adhesive coating equipment further includes a transfer device, which has a robotic arm and a connector connected to the robotic arm. The adhesive mixing device is located on the connector, and the transfer device is used to move the adhesive mixing device above the adhesive ratio detection device.

[0025] In the above technical solution, the mixing device is connected to the transfer device through a connector. The robotic arm of the transfer device can drive the mixing device to move above the glue ratio detection device, so that the first glue nozzle and the second glue nozzle can be set towards the first glue cup and the second glue cup respectively, and glue can be dispensed into the first glue cup and the second glue cup respectively, so as to quickly weigh and calculate the glue ratio of the two-component glue, eliminating the need for manual handling of the glue cup to collect glue, thus improving the automation level of the product.

[0026] In some embodiments of this application, the adhesive coating equipment further includes an industrial control computer, which is electrically connected to the adhesive mixing device and the adhesive ratio detection device, respectively.

[0027] In the above technical solution, by using an industrial control computer electrically connected to the mixing device and the glue ratio detection device, the relevant valves and drive components in the mixing device and the glue ratio detection device can be controlled to perform relevant actions, thereby improving the automation level of the product.

[0041] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0042] In the battery manufacturing process, two-component coating equipment is usually required for coating. Traditional two-component coating equipment is usually equipped with a proportioning head. Before using the coating equipment, it is necessary to check whether the proportion of the two-component mixed adhesive meets the coating process requirements. The conventional testing method is to manually disassemble the equipment and replace parts such as the proportioning head. Moreover, the disassembled proportioning head and other parts are all disposed of as scrap. This is not only cumbersome and affects battery production efficiency, but also directly leads to increased production costs.

[0043] To address the issue that manually disassembling and replacing components such as the proportioning head is required when testing whether the dispensing ratio of a two-component mixed adhesive meets the coating process requirements, and that these components are disposed of as scrap, resulting in cumbersome operation, reduced battery production efficiency, and increased production costs, this application designs a coating device. The coating device provided by this application eliminates the need for disassembly, making operation convenient, cost-effective, and improving the efficiency of verifying the dispensing ratio of the mixed adhesive.

[0044] The adhesive coating equipment disclosed in this application includes, but is not limited to, equipment for applying adhesive to the base of the tab, the top or bottom of the electrode assembly, and between adjacent battery cells or between battery cases.

[0045] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a mixing device provided in some embodiments of this application. Embodiments of this application provide a coating device, which includes a mixing device 100. The mixing device 100 includes: a first dispensing assembly, a second dispensing assembly, a mixing assembly, and a coating head 33. The first dispensing assembly includes a first storage tank, a first adhesive tube 11, a first pumping component, a first single-component valve 13, and a first dispensing nozzle 14. The first storage tank stores a first adhesive. One end of the first adhesive tube 11 is connected to the first storage tank. The first pumping component is located on the first adhesive tube 11. The first single-component valve 13 is connected to the other end of the first adhesive tube 11. The first dispensing nozzle 14 is connected to the first single-component valve 13. The second dispensing assembly includes a second storage tank, a second adhesive tube 21, a second pumping component, a second single-component valve 23, and a second dispensing nozzle 24. The storage tank is used to store the second adhesive. One end of the second adhesive tube 21 is connected to the second storage tank. The second pumping component is located on the second adhesive tube 21. The second single-component valve 23 is connected to the second adhesive tube 21. The second dispensing nozzle 24 is connected to the second single-component valve 23. The mixing assembly includes a two-component mixing valve 31 and a mixing tube 32. The two inlet ends of the two-component mixing valve 31 are respectively connected to the first adhesive tube 11 and the second adhesive tube 21. One end of the mixing tube 32 is connected to the outlet end of the two-component mixing valve 31. The applicator head 33 is connected to the other end of the mixing tube 32.

[0046] It is understandable that the first and second colloids are of different types. Before applying the adhesive to the parts, the ratio of the first and second colloids needs to be checked.

[0047] The first pumping component (not shown in the figure) can provide power for the first colloid to be conveyed along the first hose 11. The increase or decrease of power can adjust the conveying flow rate per unit time.

[0048] The second pumping component (not shown in the figure) provides power for the first colloid to be conveyed along the second hose 21. The increase or decrease of power can adjust the conveying flow rate per unit time.

[0049] In some embodiments, the first hose 11 is further provided with a first metering device, which is located on the output end side of the first pumping member. The first metering device can measure the flow rate of the first colloid and adjust the delivery flow rate of the first colloid. The second hose 21 is further provided with a second metering device, which is located on the output end side of the second pumping member. The second metering device can measure the flow rate of the first colloid and adjust the delivery flow rate of the first colloid.

[0050] For example, the first single-component valve 13 and the second single-component valve 23 are both single-component screw valves, which are driven by a servo motor and fed by an eccentric screw, so that the colloid can be continuously and stably output.

[0051] For example, the two-component mixing valve 31 has two independent valve chambers, each equipped with an independent valve core and drive mechanism. The valve core opening can be adjusted according to the feedback data from the metering device. The two-component mixing valve 31 is equipped with a mixing unit (static mixing core or micro dynamic stirring head). The first colloid and the second colloid can enter the two independent valve chambers in the valve body respectively and be quickly and evenly mixed by the mixing unit.

[0052] The glue applicator 33 is the terminal execution component of the glue applicator. Its function is to apply the mixed glue liquid to the surface of the workpiece in a specific shape, thickness and path according to the process requirements.

[0053] In some embodiments, the first rubber tube 11, the second rubber tube 21, and the mixing tube 32 are all fixed on the fixing mechanism.

[0054] By connecting one end of the first tubing 11 to the first storage tank and providing a first single-component valve 13 connected to the other end of the first tubing 11, when the first pump on the first tubing 11 is activated and the first single-component valve 13 is opened, the first adhesive can flow out from the first dispensing nozzle 14 connected to the first single-component valve 13. Similarly, by connecting one end of the second tubing 21 to the second storage tank and providing a second single-component valve 23 connected to the other end of the second tubing 21, when the second pump on the second tubing 21 is activated and the first single-component valve 13 is opened, the second adhesive can flow out from the second dispensing nozzle 24 connected to the second single-component valve 23. Furthermore, the first tubing 11 and the second tubing 21 are connected to the mixing tube 32 via a two-component mixing valve 31. In this way, when it is necessary to calculate the glue ratio when the first and second colloids are mixed, the glue dispensing amounts of the first and second colloids are weighed within the same preset dispensing time, and the glue ratio of the first and second colloids is calculated by calculating the weight ratio of the first and second colloids. This ratio can then be compared with a preset glue ratio to complete the glue ratio verification. The entire process does not require disassembling the glue application equipment or replacing parts, thus reducing material waste and increased production costs caused by disassembling parts and disposing of them as scrap. Furthermore, glue can be dispensed at any time to detect and verify the glue ratio, improving the efficiency of glue ratio detection and verification. If the calculated glue ratio is within the preset range, it indicates that the glue ratio meets the requirements. At this point, the two-component mixing valve 31, which is connected to the first glue tube 11 and the second glue tube 21, is opened to mix the first and second colloids. The mixture is then applied to the workpiece through the mixing tube 32 and the application head 33, thereby improving the glue application quality.

[0055] Specifically, the first colloid can be injected into the first receiving cup and weighed using an electronic scale. The net weight of the first colloid in a single dispensing is calculated by subtracting the weight of the first receiving cup from the total weight. The second colloid can be injected into the second receiving cup and weighed using an electronic scale. The net weight of the second colloid in a single dispensing is calculated by subtracting the weight of the second receiving cup from the total weight. Dispensing is performed three times consecutively, and the net weights of the first and second colloids are calculated for each dispensing. The colloid ratio is the ratio of the net weights of the first and second colloids. A ratio between 0.9 and 1.1 is considered acceptable. If the ratio exceeds this range for three consecutive dispensings, it indicates that the equipment parameters need to be readjusted.

[0056] According to some embodiments of this application, the other end of the first hose 11 is provided with a first three-way valve 12. The first port of the first three-way valve 12 is connected to the first hose 11, the second port of the first three-way valve 12 is connected to the first single-component valve 13, and the third port of the first three-way valve 12 is connected to one inlet end of the two-component mixing valve 31. The other end of the second hose is provided with a second three-way valve 22. The first port of the second three-way valve 22 is connected to the second hose 21, the second port of the second three-way valve 22 is connected to the second single-component valve 23, and the third port of the second three-way valve 22 is connected to the other inlet end of the two-component mixing valve 31.

[0057] For example, a first adapter is provided between the first single-component valve 13 and the first three-way valve 12, and a second adapter is provided between the second single-component valve 23 and the second three-way valve 22.

[0058] By providing a first three-way valve 12 at the other end of the first tubing 11, and connecting the first single-component valve 13 and the two-component mixing valve to the first three-way valve 12, the first adhesive can flow through the first three-way valve 12 to the first single-component valve 13 or the two-component mixing valve. Similarly, by providing a second three-way valve 22 at the other end of the second tubing 21, and connecting the second single-component valve 23 and the two-component mixing valve to the second three-way valve 22, the second adhesive can flow through the second three-way valve 22 to the second single-component valve 23 or the two-component mixing valve. The structure and principle are relatively simple and easy to implement.

[0059] Please see Figure 2 , Figure 2 This is a schematic diagram of the adhesive ratio detection device provided in some embodiments of this application. According to some embodiments of this application, the adhesive application equipment further includes an adhesive ratio detection device 200. The adhesive ratio detection device 200 includes a support assembly, a first weighing member 51, a second weighing member 52, a first adhesive receiving cup 71, and a second adhesive receiving cup 72. The support assembly is provided with a first protective member 61 and a second protective member 62. The first protective member 61 is provided with a first protective groove for accommodating the first adhesive receiving cup 71. The second protective member 62 is provided with a second protective groove for accommodating the second adhesive receiving cup 72. The first weighing member 51 is located at the bottom of the first protective member 61 and is used to weigh the weight of the first adhesive in the first adhesive receiving cup 71. The second weighing member 52 is located at the bottom of the second protective member 62 and is used to weigh the weight of the second adhesive in the second adhesive receiving cup 72.

[0060] For example, both the first weighing element 51 and the second weighing element 52 are electronic scales.

[0061] For example, both the first protective member 61 and the second protective member 62 are protective plates.

[0062] For example, the dimensions of the first protective groove and the second protective groove are adapted to the dimensions of the first adhesive receiving cup 71 and the second adhesive receiving cup 72. When the first adhesive receiving cup 71 is placed in the first protective groove, it does not contact the first protective member 61, and when the second adhesive receiving cup 72 is placed in the second protective groove, it does not contact the second protective member 62.

[0063] The first receiving cup 71 can be placed in the first protective groove of the first protective member 61. The first protective member 61 serves a protective function to improve the stability of the first receiving cup 71. After the first dispensing nozzle 14 of the adhesive applicator injects the first adhesive into the first receiving cup 71, the first weighing member 51 can be used to weigh the first receiving cup 71 to calculate the weight of the first adhesive in the first receiving cup 71. Similarly, the second receiving cup 72 can be placed in the second protective groove of the second protective member 62. The second protective member 62 serves a protective function to improve the stability of the second receiving cup 72. After the second dispensing nozzle 24 of the adhesive applicator injects the second adhesive into the second receiving cup 72, the second weighing member 52 can be used to weigh the second receiving cup 72 to calculate the weight of the second adhesive in the second receiving cup 72. Then, the adhesive ratio when the first adhesive and the second adhesive are mixed can be calculated from the weight of the first adhesive and the weight of the second adhesive.

[0064] According to some embodiments of this application, the glue ratio detection device 200 further includes a first protective cover and a second protective cover. The first protective cover is used to cover the mouth of the first glue receiving cup 71, and the second protective cover is used to cover the mouth of the second glue receiving cup 72.

[0065] For example, the first and second protective covers are cup lids.

[0066] When the first colloid is injected into the first receiving cup 71, a first protective cover can be placed over the opening of the first receiving cup 71 to reduce the risk of the first colloid overflowing due to shaking. Similarly, when the second colloid is injected into the second receiving cup 72, a second protective cover can be placed over the opening of the second receiving cup 72 to reduce the risk of the second colloid overflowing due to shaking.

[0067] According to some embodiments of this application, the support assembly includes: a support column 41; a support base plate 42 disposed on the top of the support column 41, and a first weighing member 51 and a second weighing member 52 both disposed on the support base plate 42; a drawer assembly including a fixed frame 431 and a drawer liner 432, the fixed frame 431 being fixedly connected to the support base plate 42 and the fixed frame 431 enclosing an accommodating space, the drawer liner 432 being disposed within the accommodating space and slidably connected to the fixed frame 431, a first protective member 61 and a second protective member 62 both being disposed within the drawer liner 432, the drawer liner 432 having a first opening and a second opening, the first opening and the second opening respectively corresponding to and communicating with the positions of the first protective groove and the second protective groove; wherein, an installation space is defined between the fixed frame 431 and the support base plate 42, the first weighing member 51 and the second weighing member 52 are located within the installation space and are respectively disposed corresponding to the first opening and the second opening.

[0068] For example, a handle 4321 is provided on one side of the drawer liner 432.

[0069] In some embodiments, the fixed frame 431 is provided with a locking mechanism 433, such as a locking cylinder, which is used to lock the drawer liner 432 after it has slid to a preset position.

[0070] By setting a support base plate 42 on the top of the support column 41, the first weighing member 51 and the second weighing member 52 are placed on the support base plate 42, thereby enabling the weighing of the first glue-receiving cup 71 and the second glue-receiving cup 72 under stable support. The fixing frame 431 of the drawer assembly is fixedly connected to the support base plate 42. When the drawer liner 432 is pushed and pulled, it can slide relative to the fixing frame 431 so that the drawer liner 432 can be located in a preset position within the accommodating space defined by the fixing frame 431. The first protective member 61 and the second protective member 62 are provided inside the drawer liner 432. By opening a first opening and a second opening in the drawer liner 432 that correspond to and communicate with the first protective groove and the second protective groove, the first glue-receiving cup 71 can contact the first weighing member 51 through the first opening when placed in the first protective groove, and the second glue-receiving cup 72 can contact the second weighing member 52 through the second opening when placed in the second protective groove, thereby enabling the weighing of the first glue-receiving cup 71 and the second glue-receiving cup 72.

[0071] In some embodiments, the drawer assembly is further provided with a tank chain 435 for wiring.

[0072] According to some embodiments of this application, the drawer assembly further includes a proximity sensor 434, which is disposed on one side of the fixed frame 431 along a first direction, for detecting the distance between the fixed frame 431 along the first direction and the drawer liner 432, where the first direction is the sliding direction of the drawer liner 432.

[0073] The proximity sensor 434 is a non-contact detection element that senses the proximity, presence, or distance of the drawer liner 432 without contacting it, and converts the physical signal into an electrical signal for use in detecting the position of the drawer liner 432.

[0074] By providing a proximity sensor 434 on one side of the fixed frame 431 along the first direction, when the drawer liner 432 slides relative to the fixed frame 431 along the first direction, the proximity sensor 434 can detect the distance between the drawer liner 432 and the fixed frame 431 along the first direction, thus facilitating timely stopping of the sliding when the drawer liner 432 slides close to the fixed frame 431 along the first direction and reaches a preset distance.

[0075] According to some embodiments of this application, the glue ratio detection device 200 further includes a first position sensor 64 and a second position sensor 65 disposed on the drawer assembly. The first position sensor 64 is used to detect the position of the first glue cup 71, and the second position sensor 65 is used to detect the position of the second glue cup 72.

[0076] For example, the first position sensor 64 and the second position sensor 65 are both photoelectric sensors, which are components that use the photoelectric effect to achieve non-contact detection. The core is to determine the presence or position of the first adhesive cup 71 or the second adhesive cup 72 by emitting and receiving light signals, and can convert the light signals into electrical signals for output.

[0077] By setting a first position sensor 64 and a second position sensor 65 on the drawer assembly, the first position sensor 64 is used to detect whether the first adhesive cup 71 is placed in the first protective groove, and the second position sensor 65 is used to detect whether the second adhesive cup 72 is placed in the second protective groove, so that when the first adhesive cup 71 is detected to be in the first protective groove, the first adhesive is injected into the first adhesive cup 71. Similarly, when the second adhesive cup 72 is detected to be in the second protective groove, the second adhesive is injected into the second adhesive cup 72.

[0078] According to some embodiments of this application, the glue ratio detection device 200 further includes: a first lifting mechanism disposed within the drawer liner 432, the first lifting mechanism including a first clamping member 812 and a first lifting drive member 811 connected to the first clamping member 812, the first clamping member 812 being used to clamp the first glue receiving cup 71, and the first lifting drive member 811 being used to drive the first clamping member 812 to rise or fall, thereby causing the first glue receiving cup 71 to rise or fall; and a second lifting mechanism disposed within the drawer liner 432, the second lifting mechanism including a second clamping member and a second lifting drive member 821 connected to the second clamping member, the second clamping member being used to clamp the second glue receiving cup 72, and the second lifting drive member 821 being used to drive the second clamping member to rise or fall, thereby causing the second glue receiving cup 72 to rise or fall.

[0079] For example, the first clamping member 812 and the second clamping member are both clamping cylinders, and the first lifting drive member 811 and the second lifting drive member 821 are both lifting cylinders.

[0080] When the first glue-receiving cup 71 is placed in the first protective groove, it can be held by the first clamping member 812. Then, the first lifting drive member 811 drives the first clamping member 812 to move closer to the first weighing member 51 until the first glue-receiving cup 71 is placed on the first weighing member 51, thereby enabling the first glue-receiving cup 71 to be weighed using the first weighing member 51. Similarly, when the second glue-receiving cup 72 is placed in the second protective groove, it can be held by the second clamping member. Then, the second lifting drive member 821 drives the second clamping member to move closer to the second weighing member 52 until the second glue-receiving cup 72 is placed on the second weighing member 52, thereby enabling the second glue-receiving cup 72 to be weighed using the second weighing member 52.

[0081] According to some embodiments of this application, the glue ratio detection device 200 further includes a third weighing member and at least one third glue receiving cup 73. A third protective member 63 is also provided in the drawer inner liner 432. The third protective member 63 is provided with at least one third protective groove. The drawer inner liner 432 has at least one third opening. The third opening corresponds to and communicates with the third protective groove. The third protective groove is used to accommodate the third glue receiving cup 73. The third weighing member is provided in the installation space and is provided corresponding to the third opening. It is used to weigh the weight of the mixed glue in the third glue receiving cup 73.

[0082] For example, the third weighing device (not shown in the figure) is also an electronic scale.

[0083] For example, there are multiple third protective grooves, and the number of third adhesive cups 73 is the same as the number of third protective grooves.

[0084] By providing a third protective component 63 inside the drawer liner 432, the third protective component 63 has at least one third protective groove, and the drawer liner 432 has at least one third opening corresponding to the third protective groove. When the third adhesive cup 73 is placed in the third protective groove, it can contact the third weighing component below the drawer liner 432 through the third opening. This allows the third weighing component to weigh the mixed adhesive in the third adhesive cup 73. This facilitates comparison between the measured weight of the mixed adhesive in the third adhesive cup 73 and the preset weight value of the mixed adhesive (the preset sum of the weight values ​​of the first and second adhesives). This helps determine whether there is any deviation or abnormality in the weight value of the final mixed adhesive after the two-component adhesive ratio meets the requirements. This allows operators to detect the problem in a timely manner and perform maintenance and adjustment on the adhesive application equipment.

[0085] According to some embodiments of this application, the glue ratio detection device 200 further includes at least one third position sensor 66, which is disposed inside the drawer liner 432 and is used to detect the position of the third glue receiving cup 73.

[0086] For example, the third position sensor 66 is also a photoelectric sensor.

[0087] By providing at least one third position sensor 66 in the drawer inner liner 432, the number of third position sensors 66 being the same as the number of third adhesive cups 73, the third position sensor 66 can be used to detect whether the third adhesive cup 73 has been placed in the third protective groove of the protective component. Then, when the third adhesive cup 73 is placed in the third protective groove, the adhesive mixing device 100 can inject mixed adhesive into the third adhesive cup 73 through the adhesive applicator head 33.

[0088] According to some embodiments of this application, the adhesive coating equipment further includes a transfer device, which is provided with a robotic arm and a connector connected to the robotic arm. The adhesive mixing device 100 is located on the connector, and the transfer device is used to move the adhesive mixing device 100 above the adhesive ratio detection device 200.

[0089] For example, the transfer device (not shown in the figure) can be a transfer robot.

[0090] The mixing device 100 is connected to the transfer device via a connector. The robotic arm of the transfer device can move the mixing device 100 above the glue ratio detection device 200, so that the first dispensing nozzle 14 and the second dispensing nozzle 24 can be positioned facing the first receiving cup 71 and the second receiving cup 72 respectively, and dispensing glue into the first receiving cup 71 and the second receiving cup 72 respectively, so as to quickly weigh and calculate the glue ratio of the two-component glue, eliminating the need for manual handling of the receiving cups and improving the automation level of the product.

[0091] According to some embodiments of this application, the adhesive coating equipment also includes an industrial control computer (not shown in the figure), which is electrically connected to the adhesive mixing device 100 and the adhesive ratio detection device 200, respectively.

[0092] For example, the industrial control computer is electrically connected to the first weighing device 51, the second weighing device 52, and the third weighing device, and is equipped with a calculation module and an alarm module. The calculation module can calculate the glue ratio when the first and second colloids are mixed based on the weights of the first and second colloids weighed. It can also compare the weight of the mixed colloid weighed by the third weighing device with a preset value, and if there is a deviation, it will control the alarm module to sound an alarm.

[0093] The industrial control computer is also electrically connected to the first pumping component, the second pumping component, the first single-component valve 13, the second single-component valve 23, the two-component mixing valve 31, and the glue application head 33 of the glue application device.

[0094] The industrial computer is also electrically connected to various sensors and drive components in the transfer device and the glue ratio detection device 200.

[0095] An industrial control computer electrically connected to the mixing device 100 and the glue ratio detection device 200 can control the relevant valves and drive components in the mixing device 100 and the glue ratio detection device 200 to perform relevant actions, thereby improving the automation level of the product.
