Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to an automatic glue scraping equipment. BACKGROUND

[0002] In current production processes, the bonding part of the box is crucial, and double-sided tape as a common material for bonding is particularly prominent in this process. In today's production processes, double-sided tape, as a commonly used material widely used to bond different materials together, plays a crucial role. Generally, the bottom paper of the double-sided tape is attached to it, and when needed, the cutting of the bottom paper often needs to rely on manual or automatic operation. This traditional way has obvious shortcomings, not only leading to a large amount of waste of bottom paper, but also increasing labor costs.

[0003] Firstly, manual or semi-automatic cutting is easily disturbed by human factors, leading to inaccurate and inconsistent cutting. This can lead to increased waste of bottom paper, affect the bonding quality, and increase the risk of defective products. Secondly, for boxes of different shapes and sizes, frequent adjustments and operations are needed, thus reducing production efficiency. In addition, manual cutting methods cannot meet the needs of modern manufacturing for high automation and digitization, limiting the overall efficiency of the production line.

[0004] Compared with the traditional technology, these limitations highlight the need for more advanced and efficient automatic glue scraping equipment. The introduction of new equipment aims to overcome these problems of traditional technology, through innovative design and precise control, to achieve high-precision glue scraping operation on the bonding part of the box and efficient operation in the entire manufacturing process. Such an automated solution will bring higher production efficiency, quality consistency and sustainability to the box manufacturing industry, ushering in a new direction for the industry to move towards intelligent production.

Obviously, the described embodiments are only a part of the embodiments of this application, not all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of this application.

[0048] Please refer to Figures 1 to 4 This application first provides an embodiment of an automatic glue scraping equipment, which will be described in detail as follows, which comprises:

[0049] The rack assembly 1 and the upper feeding assembly 2, the rotating disc assembly 3, the first glue scraping assembly 4, the second glue scraping assembly 5 and the lower feeding assembly 6 arranged on the rack assembly 1. The first glue scraping assembly 4, the second glue scraping assembly 5 and the lower feeding assembly 6 are arranged around the rotating disc assembly 3. The rotating disc assembly 3 is provided with a product station 30. The upper feeding assembly 2 is used to convey the product to be scraped to the product station 30 on the rotating disc assembly 3. The rotating disc assembly 3 transmits the product to be scraped on the product station 30 to the corresponding working area of the first glue scraping assembly 4, the second glue scraping assembly 5 and the lower feeding assembly 6 in turn by rotating. The first glue scraping assembly 4 performs glue scraping treatment on the first position of the product to be scraped. The second glue scraping assembly 5 performs glue scraping treatment on the second position of the product to be scraped. The lower feeding assembly 6 feeds the product after glue scraping from the product station 30.

[0050] The detailed description of this automatic glue scraping equipment embodiment is as follows:

[0051] Rack assembly 1:

[0052] Rack assembly 1 provides the infrastructure of the machine, offering support and stability as the main frame of the entire system.

[0053] Feeding assembly 2:

[0054] Located on the rack assembly 1, the feeding assembly 2 is responsible for transferring the product to be coated from the previous process in the production line to the product station 30 on the carousel assembly 3. This can include a conveyor belt, a transfer mechanism, a robot arm, or other automated motion modules.

[0055] Carousel assembly 3:

[0056] Located on the rack assembly 1, the carousel assembly 3 is a rotatable platform with product stations 30 arranged on it. The carousel assembly 3 transfers the product to be coated on the product stations 30 to different work areas, including the first coating assembly 4, the second coating assembly 5, and the unloading assembly 6, in a rotating manner.

[0057] First coating assembly 4:

[0058] Arranged around the carousel assembly 3, the first coating assembly 4 is responsible for coating the first position of the product to be coated in the working process of the machine. For example, the first coating assembly 4 can include a coating knife or coating head, which can achieve precise coating of the first position through precise control.

[0059] Second coating assembly 5:

[0060] Similar to the first coating assembly 4, the second coating assembly 5 is arranged around the carousel assembly 3 and is responsible for coating the second position of the product to be coated. The design of this embodiment allows the machine to coat different positions in the same working process to meet the needs of different products.

[0061] Unloading assembly 6:

[0062] Also arranged around the carousel assembly 3, the unloading assembly 6 is responsible for removing the coated product from the product station 30 and performing unloading in the working process of the machine. This assembly can be achieved through an automated robotic arm, a conveyor belt, or other motion modules.

[0063] In this application, the first coating assembly 4, the second coating assembly 5, and the unloading assembly 6 are arranged around the carousel assembly 3. These three assemblies can be arranged around the center of rotation of the carousel assembly, and they can be evenly spaced according to a certain rotation angle.

[0064] Working process:

[0065] The product to be coated is transferred by the feeding assembly 2 to the product station 30 on the carousel assembly 3.

[0066] The rotary disc assembly 3 rotates to sequentially transfer the product on the product station 30 to the corresponding working areas of the first glue scraping assembly 4, the second glue scraping assembly 5, and the unloading assembly 6.

[0067] The first glue scraping assembly 4 performs glue scraping treatment on the first position of the product.

[0068] The second glue scraping assembly 5 performs glue scraping treatment on the second position of the product.

[0069] In this application, the first position and the second position of the product can refer to two different areas on the product that require glue scraping treatment, for example, the first position can be two strip-shaped areas located on both sides of the second position, and the second position can be a rectangular area in the center of the product. The first position and the second position can be adjusted according to the actual glue scraping needs of the product.

[0070] The unloading assembly 6 unloads the product after glue scraping from the product station 30, completing the entire glue scraping process.

[0071] Such an automatic glue scraping equipment embodiment realizes efficient and precise glue scraping operation through reasonable layout and automatic control, reduces manual intervention, and improves production efficiency. The equipment structure is compact and suitable for various product shapes and sizes.

[0072] In the embodiment of the present application, the design of the rotary disc assembly 3 allows the product to be rotated and transferred between different working areas, which enables the equipment to realize multi-station operation. The product can sequentially pass through different processing steps on the same equipment, thereby improving production efficiency.

[0073] The operation of the rotary disc assembly 3 enables the entire glue scraping process to be continuously performed without stopping. The product is continuously transferred on the rotary disc without waiting, thereby reducing the idle time of the production line and improving production efficiency. The operation of the rotary disc assembly 3 can be precisely controlled by an automatic control system. This automatic control enables the transfer of the product between different working areas to be highly precise and synchronized, ensuring the accuracy of each process. The automatic transfer process of the rotary disc assembly 3 reduces the dependence on manual operation. The product is automatically transferred on the rotary disc, reducing the burden on the operator and reducing labor costs. The compact design of the rotary disc assembly 3 effectively utilizes the space of the equipment. The product passes through multiple processes on the same equipment without occupying multiple independent equipment, improving the space utilization efficiency.

[0074] In an optional embodiment, the rotary disc assembly 3 is provided with 4 product stations 30, and the positions of the 4 product stations 30 are respectively aligned with the working areas of the feeding assembly 2, the first glue scraping assembly 4, the second glue scraping assembly 5, and the unloading assembly 6.

[0075] In this optional embodiment, the carousel assembly 3 is provided with 4 product stations 30, each of which is aligned with the working area of the feeding assembly 2, the first glue scraping assembly 4, the second glue scraping assembly 5 and the discharging assembly 6 respectively. This design helps to coordinate the operation of the entire glue scraping equipment more effectively.

[0076] In this embodiment, the carousel assembly 3 is a rotating platform provided with 4 product stations 30. This carousel can be rotated by a motor or other driving device. Each product station 30 is precisely placed at a different position on the carousel, ensuring that each station is aligned with a specific working area. For example, the 4 product stations 30 are evenly and equally spaced on the carousel assembly 3, and the angle between the 4 stations can be 90 degrees.

[0077] In this embodiment, the alignment of each product station with the working area of each assembly means that each time a product station is rotated to the working area of a component, the other product stations are located in the working area of the corresponding component. That is, after each rotation of the carousel assembly 3, each component can process the product on the corresponding product station.

[0078] Each product station 30 is aligned with the working area of the feeding assembly 2, the first glue scraping assembly 4, the second glue scraping assembly 5 and the discharging assembly 6 respectively. Such alignment helps to ensure smooth transfer of products during the entire glue scraping process, avoiding problems caused by inaccurate positions.

[0079] The task of the feeding assembly 2 is to transfer the product to be glued to the product station 30 on the carousel assembly 3. Since the product station 30 is aligned with the working area of the feeding assembly 2, the transfer process is more convenient, reducing the adjustment of the product position. Each of the two glue scraping assemblies corresponds to a different position of the product station 30. Because the product station 30 is aligned with the working area, the glue scraping assembly can accurately glue the product at a specific position, ensuring the accuracy and consistency of the glue scraping. The discharging assembly 6 is responsible for taking the glued product off the product station 30. Since the product station 30 is aligned with the working area of the discharging assembly 6, the discharging process is smoother, improving the efficiency of product removal.

[0080] In this embodiment, since 4 product stations 30 are provided, each corresponding to the working area of 4 components, when a specific process is completed, the carousel assembly 3 rotates at a precise angle to smoothly transfer the product on the previous product station 30 to the next working area. Through this mechanism, the equipment can achieve automatic and precise product transfer between different working areas, ensuring the continuity and efficiency of the entire production process.

[0081] This embodiment allows each product to move quickly and accurately to the next stage after completing a process. By controlling the rotation angle of the carousel assembly 3, the system can accurately position and transfer products without interrupting the operation of the production line, helping to minimize the production line's idle time and improve overall production efficiency.

[0082] In this application, the carousel assembly 3 rotates to load the products, that is, the carousel assembly 3 not only needs to have a rotating function, but also needs to keep the products stable during loading. For this purpose, the application also provides some possible implementation ways. For the realization of the rotating function, the following structures can be used:

[0083] Mechanical carousel: uses mechanical structure, such as mechanical carousel with gear or chain transmission system

[0084] Electric carousel: uses electric drive device, such as motor, to drive the rotation of the carousel. This way can adjust the rotation speed and angle through electronic control system, and is suitable for production environment requiring high precision and high automation degree.

[0085] Pneumatic carousel: uses pneumatic elements, such as air cylinder or fan, to control the rotation of the carousel.

[0086] Hydraulic carousel: uses hydraulic system to realize the rotation of the carousel.

[0087] Servo-driven carousel: combines servo motor and control system to realize high-precision control of the position of the carousel.

[0088] For the fixation of products on the carousel assembly 3, the application also provides some possible implementation ways, for example:

[0089] Clamp or jaw: designed to be fixed on the carousel, which can be controlled by mechanical handle or pneumatic system. The clamp can be customized according to the shape of the product to ensure the stability of the product during transfer.

[0090] Vacuum chuck system: uses vacuum chuck to adsorb the surface of the product to ensure the firm fixation of the product on the carousel.

[0091] Magnetic fixation: if the product has magnetic material, magnetic fixation system can be considered to fix the product on the carousel through magnetic attraction.

[0092] Cam and groove design: design cam and matching groove on the carousel, so that the specific part of the product can be embedded in the groove to ensure the fixation of the product during rotation.

[0093] Fixed clamp and spring system: uses clamp to fix the product, and adds spring system between the clamp and the product to absorb the vibration during transfer and improve the stability of the product.

[0094] Referring to Figure 5 and Figure 6 The preferred embodiment of the carousel assembly 3 is provided with a carousel 31, a suction chamber 32 connected to a negative pressure machine through a pipeline, and a suction accessory 33 connected to the suction chamber 32 through a pipeline. The product station 30 is arranged on the carousel 31, and the suction accessory 33 is arranged on the product station 30 to fix the product by negative pressure.

[0095] The detailed description of each component of the preferred embodiment is as follows:

[0096] Carousel 31: The carousel 31 is the core part of the entire assembly, which is used to support and transfer products. The carousel 31 can be a circular rotating platform.

[0097] Suction chamber 32: The suction chamber 32 is arranged on the carousel assembly 3, which is a closed area connected to the negative pressure machine through a pipeline. The suction chamber 32 can be connected to the negative pressure machine through a pipeline and a suction flange. The suction chamber 32 creates a negative pressure environment through the negative pressure machine to control the fixation of the product on the station. In order to facilitate the rotation of the carousel 31, the suction chamber 32 can be arranged in the central area of the carousel 31.

[0098] Suction accessory 33: The suction accessory 33 is located on the product station 30 and connected to the suction chamber 32 through a pipeline. The function of the suction accessory 33 is to fix the product by negative pressure, ensuring that the product is firmly fixed on the station during the transfer process.

[0099] Product station 30: The product station 30 is arranged on the carousel 31 to fix the product to be processed.

[0100] Negative pressure machine: The negative pressure machine is connected to the suction chamber 32 through a pipeline and is responsible for creating a negative pressure environment in the suction chamber 32. This design allows the product to be firmly fixed on the product station 30 by the negative pressure in the suction chamber 32.

[0101] The carousel 31 moves the product station 30 to different working areas by rotation, facilitating processing in each process. On the product station 30, the suction accessory 33 creates a negative pressure environment through the negative pressure machine, thereby firmly adsorbing the product on the station. The design of the carousel assembly 3 allows continuous operation, and the product passes through each working area in different processes while maintaining stable fixation.

[0102] The advantage of this embodiment is that through the synergy of the negative pressure machine, the air suction cavity 32 and the suction accessory 33, reliable fixation of the product is achieved, ensuring the stability of the product during high-speed transmission. Such a design enables the entire automatic glue scraping equipment to achieve highly precise automatic transmission between different work areas, improving the efficiency and reliability of the entire production process.

[0103] Referring to Figure 5 , Figure 6 and Figure 7 , specifically, the suction accessory 33 is used to fix the product through negative pressure. The present application provides a specific embodiment of a suction accessory 33, which includes a suction plate 331 and a suction base 332. The suction plate 331 is arranged above the suction base 332. The suction base 332 is connected to the suction cavity 32 through a suction pipe flange 333. The suction plate 331 has air holes 334 that are connected to the suction pipe flange 333. When the product is placed on the suction plate 331, it is fixed by negative pressure through the air holes 334.

[0104] The following is a detailed description of this suction accessory 33:

[0105] In this embodiment, the suction plate 331 is the main component of the suction accessory 33 and is arranged above the suction base 332. The suction plate 331 has air holes 334 on its surface, through which the product is fixed by negative pressure. The suction base 332 is located below the suction plate 331 and serves to support and connect the suction plate 331. The suction plate 331 is connected to the suction cavity 32 through the suction pipe flange 333, allowing it to work in conjunction with the negative pressure machine through the suction base 332. The air holes 334 on the surface of the suction plate 331 are connected to the suction pipe flange 333. This design ensures that the negative pressure generated by the negative pressure machine can be transmitted to the suction plate 331 through the suction pipe flange 333 and the suction base 332, forming a negative pressure suction.

[0106] The suction base 332 is connected to the suction cavity 32 through the suction pipe flange 333, transmitting the negative pressure generated by the negative pressure machine to the air holes 334 of the suction plate 331. This transmission mechanism ensures that when the product is placed on the suction plate 331, the negative pressure acts on the surface of the product through the air holes 334, achieving reliable negative pressure fixation.

[0107] In this embodiment, when the product is placed on the suction plate 331, the negative pressure generated by the air holes 334 creates a suction force between the product and the surface of the suction plate 331, thereby achieving fixation of the product. This fixation method is highly precise and reliable.

[0108] In the foregoing embodiment, the product station 30 on the rotary disc 31 is connected with the suction cavity 32 through the air passage. During operation, the rotary disc 31 rotates. In order to ensure the air tightness between the rotary disc 31 and the suction cavity 32, the present application provides an embodiment of the specific structure of the rotary disc 31. The rotary disc 31 is provided with a first sub-suction part 311. The first sub-suction part 311 is provided with a first air hole 310. The suction cavity 32 is connected with the suction accessory 33 through the first air hole 310. The suction cavity 32 is provided with a cylinder 321 and a plug 322. The plug 322 is connected with the cylinder shaft of the cylinder 321. The cylinder 321 controls the plug 322 to close or open the first air hole 310 on the first sub-suction part 311.

[0109] Referring to Figure 5 , Figure 6 and Figure 7 , in the embodiment, the rotary disc 31 is provided with a first sub-suction part 311. The first sub-suction part 311 is connected with the suction cavity 32 through the air passage. The first sub-suction part 311 is provided with a first air hole 310. Through the air hole 310, the suction cavity 32 is connected with the suction accessory 33. This ensures that the negative pressure system can effectively act on the product station 30. The suction cavity 32 is provided with a cylinder 321 and a plug 322. The cylinder 321 is connected with the plug 322 through the cylinder shaft. The cylinder controls the movement of the plug 322 to close or open the first air hole 310. The cylinder 321 is connected with the control system to ensure accurate control of the cylinder 321. The control system can control the movement of the cylinder shaft to control the closing or opening state of the plug 322 on the first air hole 310. The plug 322 is connected with the cylinder shaft 321. Through the movement of the cylinder 321, the plug 322 can close or open the first air hole 310. During the operation of the rotary disc 31, the connection state between the suction cavity 32 and the product station 30 can be flexibly controlled by controlling the cylinder 321, so as to control the fixing and release of the product.

[0110] Referring to Figure 5 , Figure 6 and Figure 7 , based on the foregoing embodiment, in order to further ensure the air tightness between the rotary disc 31 and the suction cavity 32, the suction cavity 32 is provided with a second sub-suction part 323. When the rotary disc 31 rotates, the first sub-suction part 311 and the second sub-suction part 323 move relatively. The second sub-suction part 323 is provided with a second air hole 320. When the rotary disc 31 is stationary, the position of the second air hole 320 corresponds to the first air hole 310 and constitutes an air passage connecting the suction accessory 33 and the suction cavity 32. The plug 322 cooperates with the hole of the second air hole 320 to close or open the air passage.

[0111] The second sub-suction part 323 is arranged in the suction chamber 32, and the first sub-suction part 311 moves relative to the second sub-suction part 323 when the rotating disc 31 rotates. The second air hole 320 is arranged on the second sub-suction part 323. When the rotating disc 31 is stationary, the position of the second air hole 320 corresponds to the first air hole 310, forming an air passage connecting the suction accessory 33 and the suction chamber 32. The plug cooperates with the orifice of the second air hole 320, so that the air passage can be closed or opened. When the plug cooperates with the second air hole 320, the air passage is closed, ensuring that the air tightness is maintained when the negative pressure mechanism is not needed. When the plug is away from the second air hole 320, the air passage is opened, allowing the negative pressure mechanism to suck the product. With the movement of the rotating disc 31, the position of the second air hole 320 relative to the first air hole 310 changes, and through the dynamic control of the plug, the precise control of the air tightness is realized.

[0112] When the rotating disc 31 is stationary, the position of the second air hole 320 corresponds to the first air hole 310, and the plug closes the air passage to maintain air tightness. With the rotation of the rotating disc 31, the relative position of the second air hole 320 changes, and the plug 322 controls the state of the air passage accordingly, so that the air passage is opened when needed, and the negative pressure mechanism can work. That is, in this specific embodiment, the plug 322 directly plugs the orifice of the second air hole 320. In practice, the first sub-suction part 311 is located inside the second sub-suction part 323 and closely fits the second sub-suction part 323, thereby ensuring air tightness without affecting the rotation of the rotating disc 31. The closely fitted gap can be filled with lubricating grease to ensure lubrication while also serving as an air tightness function.

[0113] In practice, when four product stations 30 are provided, the position of the plug 322 can be aligned with the feeding station, and four first air holes 310 and four second air holes 320 are provided. The rotating disc 31 can be driven to rotate by a cam divider, and each time it is intermittently rotated by an angle, the first air hole 320 and the second air hole 320 are aligned to form an air passage. The product station 30 that reaches the working area of the feeding assembly 6 is driven by a cylinder to plug the second air hole 320 with the plug, so that the negative pressure suction is disconnected, thereby releasing the product on the product station 30 for feeding.

[0114] The advantage of this improved embodiment is that by dynamically adjusting the position of the second air hole 320 and controlling the plug, precise air tightness can be maintained when the rotating disc 31 rotates and is stationary. This design not only improves the reliability of the system, but also better adapts to the changes in the movement of the rotating disc 31, so that the entire automatic glue scraping equipment can maintain high efficiency and stable performance in various operating states.

[0115] In this application, the unloading assembly 6 is used to unload the product from the designated product station 30 to the next process, which can be achieved in various ways, such as through a mechanical arm, a clamping device, a motion module, etc. automatic module, see Figure 8 In this application, an embodiment of the unloading assembly 6 is provided, which includes:

[0116] The structure includes: support frame 61, transfer motion module 62, feeding cylinder 63 and suction cup assembly 64, the transfer motion module 62 is provided with sliding table 65, the transfer motion module 62 is fixed on the support frame 61, the feeding cylinder 63 is fixed on the sliding table 65, the suction cup assembly 64 is connected with the cylinder shaft of the feeding cylinder 63, the suction cup assembly 64 is used for adsorbing product, the feeding cylinder 63 drives the suction cup assembly 64 to move up and down, the transfer motion module 62 drives the suction cup assembly to move the product to the product station 30 or move away from the product station 30 through the sliding table 65.

[0117] The following is a detailed description of this embodiment:

[0118] Support frame 61: The support frame 61 is the basis of the entire structure, used to stabilize and support the transfer motion module 62, the feeding cylinder 63 and the suction cup assembly 64.

[0119] Transfer motion module 62: The transfer motion module 62 is fixed on the support frame 61 and has a sliding table 65. This module is responsible for moving the suction cup assembly 64 to move the product from the designated position to the product station 30 or away from the product station 30.

[0120] Feeding cylinder 63: The feeding cylinder 63 is fixed on the sliding table 65 and connected with the suction cup assembly 64 through the cylinder shaft. The function of the feeding cylinder 63 is to control the up and down movement of the suction cup assembly 64 through the cylinder shaft, realizing the adsorption and transfer of the product.

[0121] Suction cup assembly 64: The suction cup assembly 64 is located on the cylinder shaft of the feeding cylinder 63 and is used to adsorb the product. The design of the suction cup assembly 64 enables it to effectively generate adsorption force with the product surface, ensuring the stability of the product during the transfer process.

[0122] Working principle:

[0123] Adsorbing product: The feeding cylinder 63 controls the suction cup assembly 64 to move down through the cylinder shaft, so that the suction cup assembly 64 contacts and adsorbs the product.

[0124] The product is moved to the product station 30: the transfer movement module 62 drives the slide 65 to move the suction cup assembly 64 with the product to the designated product station 30. Or move away from the product station 30: according to the needs, the transfer movement module 62 controls the slide 65 to move the suction cup assembly 64 away from the product station 30, completing the unloading process.

[0125] Because the positions of the multiple product stations 30 on the rotating disc have periodicity and fixity, it can be ensured that the feeding assembly 2 and the unloading assembly 6 adopt the same structural design to adapt to the periodic change of the product position. The same type and specification of transfer movement module 62, feeding cylinder 63 and suction cup assembly 64 can be used to ensure that they can be used in the feeding and unloading assemblies 6. This reduces the cost of spare parts inventory and facilitates maintenance and replacement. Because the structure and jig of the product station 30 are consistent, the feeding and unloading actions can be realized by the same control logic, maintaining the consistency of the operation. This is beneficial to the operation and maintenance of the equipment. The improvement of universality and consistency makes the equipment more adaptable, which can flexibly adapt to different types of products without the need for large-scale adjustment or change of the feeding and unloading assemblies 6.

[0126] The automatic glue scraping equipment provided in the present application is provided with two groups of glue scraping assemblies, which are respectively used for scraping glue on the first position 001 and the second position 002 of the product. One embodiment of the first position 001 and the second position 002 of the product can be referred to Figure 14 The two groups of glue scraping assemblies can adopt the same structure and only perform different scraping actions or trajectories during scraping, or different structures can also be adopted.

[0127] Referring to Figure 9 and Figure 10 , an embodiment of the specific glue scraping assembly in the present application is provided below, which includes:

[0128] The glue scraping fixed structure 41, the first direction movement module 42, the second direction movement module 43 and the glue scraping gun 44, the glue scraping assembly provided by the embodiment is designed to realize high degree of freedom movement track by the cooperation of the two direction movement modules, complete the glue scraping of the product, therefore, the first direction and the second direction are not limited, which can be a certain angle, or perpendicular to each other, or other layout, as long as the movement control of the glue scraping gun 44 can be realized. The first direction movement module 42 is fixed on the glue scraping fixed structure 41, the second direction movement module 43 is connected to the first direction movement module 42, the glue scraping gun 44 is connected to the second direction movement module 43, the first direction movement module 42 drives the second direction movement module 43 and the glue scraping gun 44 to move in the first direction, and the second direction movement module 43 drives the glue scraping gun 44 to move in the second direction.

[0129] The following is a detailed description of the glue scraping assembly embodiment:

[0130] Glue scraping fixed structure 41: the glue scraping fixed structure 41 is the basis of the whole assembly, used to stabilize and support the first direction movement module 42, the second direction movement module 43 and the glue scraping gun 44.

[0131] First direction movement module 42: the first direction movement module 42 is fixed on the glue scraping fixed structure 41, responsible for driving the second direction movement module 43 and the glue scraping gun 44 to move in the first direction. This module enables the whole glue scraping assembly to realize precise movement in one-dimensional direction.

[0132] Second direction movement module 43: the second direction movement module 43 is connected to the first direction movement module 42, driven by the first direction movement module 42, responsible for making the glue scraping gun 44 move in the second direction. This module enables the glue scraping gun 44 to realize precise movement in the direction perpendicular to the first direction.

[0133] Glue scraping gun 44: the glue scraping gun 44 is connected to the second direction movement module 43, responsible for the actual glue scraping operation. The design of the glue scraping gun 44 enables it to move in the first and second directions to ensure precise glue scraping on the surface of the product.

[0134] Working principle:

[0135] First direction movement: the first direction movement module 42 drives the second direction movement module 43 and the glue scraping gun 44 to make precise movement in the first direction through the driving mechanism. The movement in this direction can be related to the glue scraping track on the surface of the product.

[0136] Second direction movement: The second direction movement module 43 is driven by the first direction movement module 42, realizing the precise movement of the glue scraping gun 44 in the direction perpendicular to the first direction. This ensures that the glue scraping gun 44 can perform accurate scraping actions in both directions.

[0137] The advantage of this embodiment is that through the cooperation of the first direction movement module 42 and the second direction movement module 43, high-precision movement in two directions during the glue scraping process is realized. This design ensures the accuracy and consistency of glue scraping, which helps to improve the quality and production efficiency of the product.

[0138] In order to be able to make some fine adjustment to the glue scraping assembly to ensure that it can adapt to more types and sizes of products, thereby improving the application scenarios of the automatic glue scraping equipment, the application also provides a further embodiment of a glue scraping assembly, which further comprises a lead screw, a nut 52 and a hand wheel 53, the first direction movement module 42 is fixed on the nut 52, the lead screw is threadedly connected with the nut 52, and the hand wheel 53 is arranged on the lead screw. When the hand wheel 53 rotates, it drives the lead screw to rotate, so that the nut 52 drives the first direction movement module 42 to move along the lead screw. In this embodiment, the lead screw is an elongated threaded shaft used to transmit rotary motion.

[0139] The nut 52 is a part matched with the lead screw and connected with the lead screw through thread cooperation. The fixed position of the nut 52 allows it to move on the lead screw with the rotation of the lead screw. The shape of the nut 52 can be designed according to actual needs, and its shape is not limited to the traditional circular or hexagonal shape of the nut 52.

[0140] The hand wheel 53 is arranged on the lead screw, and the rotation direction and speed of the lead screw can be changed by manually rotating the hand wheel 53. The design of the hand wheel 53 makes fine adjustment convenient, and the operator can realize fine adjustment of the glue scraping assembly by rotating the hand wheel 53.

[0141] The operator rotates the hand wheel 53, and the movement of the hand wheel 53 is transmitted to the lead screw, causing the rotation of the lead screw. The rotation of the lead screw moves the nut 52 up and down along the axis of the lead screw through thread cooperation with the nut 52.

[0142] The up-and-down movement of the nut 52 drives the first direction movement module 42 to fine adjust. This fine adjustment process can realize the fine adjustment of the position of the glue scraping assembly in one direction, for example, making the glue scraping assembly closer to or farther away from the product station 30 in the horizontal direction.

[0143] In an optional embodiment, in order to better fine-tune the position of the glue scraping assembly, a linear guide rail 54 can also be provided, and the first direction movement module 42 is connected with the glue scraping fixed structure 41 through the linear guide rail 54. That is, when the position is adjusted through the hand wheel 53, the first direction movement module 42 can realize directional displacement through the linear guide rail 54, ensuring the stability of the first direction movement module 42.

[0144] In an optional embodiment, a glue gun fixing block 55 and a heat insulation block 56 are further included, and the glue scraping gun 44 is fixed with the glue gun fixing block 55 through the heat insulation block 56, and the glue gun fixing block 55 is fixed on the second direction movement module 43.

[0145] The glue gun fixing block 55 in this embodiment is a part for fixing the glue scraping gun 44, ensuring that the glue scraping gun 44 remains stable during operation. The glue gun fixing block 55 is fixed on the second direction movement module.

[0146] The heat insulation block 56 is a block of heat insulating material, used to isolate the heat of the glue scraping gun. In the glue scraping operation, the glue scraping gun 44 can be heated, and by using the heat insulation block 56, heat transmission to other components can be prevented, protecting the stability and durability of the entire glue scraping assembly. The glue scraping gun 44 is connected with the glue gun fixing block through the heat insulation block 56, and since the glue gun fixing block 55 is fixed on the second direction movement module 43, the entire glue scraping gun 44 is linked with the second direction movement module 43.

[0147] The heat insulation block 56 acts as a heat insulation layer in the glue scraping operation, preventing heat from the glue scraping gun 44 from being transmitted to other components, especially the second direction movement module 43. This helps to prevent the negative effects of temperature changes on the performance of the equipment.

[0148] In this application, the product is moved to the product station 30 of the turntable 31 by the feeding assembly 2. Due to the characteristics of the feeding of the turntable 31, when the product moves around the work area of multiple assemblies through the turntable 31, it always remains fixed with the product station 30 until it is rotated to the work area of the discharging assembly 6. In order to better and more accurately implement glue scraping on the first position 001 and the second position 002 on the product, the product needs to be positioned, that is, to ensure that the position of the product on the product station 30 is accurate and stable. Therefore, referring to Figure 11 , this application provides an optional embodiment, in which the automatic glue scraping equipment further comprises a product positioning assembly 7 for positioning the glue scraping product before entering the product station 30, and the product positioning assembly 7 comprises:

[0149] The product positioning block 71, the raised bottom plate 72, the pushing cylinder 73 and the pushing block 74, the product to be coated is placed on the raised bottom plate 72, the pushing cylinder 73 is arranged on one side of the raised bottom plate 72, the pushing block 74 is connected with the cylinder shaft of the pushing cylinder 73, and the product on the raised bottom plate 72 is pushed, and the product positioning block 71 is arranged on the side of the raised bottom plate 72 opposite to the pushing cylinder 73. A positioning support structure 75 can also be provided for mounting each component in the product positioning assembly 7. For example, the raised bottom plate 72, the pushing cylinder 73 and the product positioning block 71 can be mounted on the positioning support structure 75, and the positioning support structure 75 can be mounted on the rack assembly 1.

[0150] In this embodiment, the product positioning assembly is used to position the product to be coated before entering the product station 30, and the principle of the product positioning assembly is as follows:

[0151] The product to be coated is conveyed to the raised bottom plate 72, one side of the raised bottom plate 72 is provided with the product positioning block 71, and the opposite side is provided with the pushing cylinder 73 and the pushing block 74, the pushing cylinder 73 drives the pushing block 74 to move forward and push the product on the raised bottom plate 72, and the other end of the product is pushed against the product positioning block 71, so as to realize positioning. It should be noted that in this embodiment, positioning can be achieved by providing two or more sets of pushing cylinders 73, pushing blocks 74 and corresponding product positioning blocks 71. For example, two sets can be provided, i.e. pushing the product in two perpendicular directions to cooperate with the corresponding product positioning block 71 for positioning. The positioned product is moved to the product station 30, which can ensure that the position of the product on the product station 30 is always consistent.

[0152] Referring to Figure 12 and 13 In an optional embodiment, the automatic coating equipment of the present application further comprises a lifting feeding assembly 8, the lifting feeding assembly 8 comprises a lifting module 81, a lifting column 82 and a product fixing disc 83, the lifting column 82 is connected with the lifting module 81, the product fixing disc 83 is fixed on the top of the lifting column 82, the product is fixed on the product fixing disc 83, and the lifting module 81 drives the lifting column 82 to lift for feeding.

[0153] In this embodiment, the lifting module 81 is a mechanical module for controlling lifting movement. It can realize vertical lifting movement through motor, cylinder and the like. The lifting column 82 is a structural element connecting the lifting module 81 and the product fixing disc 83, and realizes vertical movement of the lifting column 82 through control of the lifting module 81.

[0154] The product fixing plate 83 is a platform for fixing the products to be coated on the feeding assembly 2. The products are placed or clamped on the product fixing plate 83 to ensure their stable position during the feeding process. The products to be coated are fixed on the product fixing plate 83, which can be achieved by clamps, clamping devices, etc., to ensure the fixation of the products during the lifting movement. The lifting module 81 drives the product fixing plate 83 to rise or fall by controlling the movement of the lifting column 82. This movement enables the products to be accurately transferred to the working area of the next assembly. In this embodiment, the lifting module 81 can use various types of movement modules, and the preferred embodiment uses an electric drive screw module, which includes a driving motor, a screw rod, and a nut sliding table, etc.

[0155] The advantage of this optional embodiment is that a lifting feeding assembly is introduced, through which accurate lifting movement of the products to be coated can be achieved, thereby ensuring the stability and accuracy of the products during the feeding process.

[0156] Further, based on the lifting feeding assembly in the foregoing embodiments, a moving plate 84 and a moving track 85 are further included, the moving plate 84 is connected to the rack assembly 1 through the moving track 85, a linear bearing 86 is arranged on the moving plate 84, the lifting column 82 is connected to the moving plate 84 through the linear bearing 86, and the moving plate 84 drives the lifting column 82 to move when moving on the moving track 85.

[0157] In this embodiment, the moving plate 84 is a plate-shaped structure connected to the rack assembly 1, and a linear bearing 86 is arranged thereon. The design of the moving plate 84 enables it to move in the horizontal direction on the moving track 85. The moving track 85 is a track structure connected to the rack assembly 1, through which the moving plate 84 can move linearly in the horizontal direction. The linear bearing 86 is arranged on the moving plate 84 for connecting the lifting column 82. The design of the linear bearing 86 enables the lifting column 82 to move up and down relative to the moving plate 84 in the vertical direction. The moving plate 84 is connected to the lifting column 82 through the linear bearing 86 and is arranged on the moving track 85, through which structure the lifting column 82 can move up and down on the moving plate 84. The lifting module controls the movement of the lifting column 82 to make it move up and down in the vertical direction, and through the movement of the moving plate 84 on the moving track 85, the entire lifting module can also move in the horizontal direction. This ensures the accurate positioning of the product fixing plate in the horizontal and vertical directions. Under the synergistic action of horizontal movement and vertical lifting, the lifting feeding assembly transfers the products from the lifting module to the next process.

[0158] In an optional embodiment, the end of the moving track 85 is provided with a buffer 87.

[0159] In this embodiment, the buffer 87 is arranged at the end of the moving track 85 to slow down or absorb the impact or vibration of the end of the horizontal movement of the moving plate 84. The buffer 87 can be a spring, air cushion or other damping material to ensure that the lifting and feeding assembly can stop smoothly at the end of the movement.

[0160] When the moving plate 84 moves horizontally on the moving track 85 to the end, the buffer 87 slows down or absorbs the impact, preventing the vibration or vibration caused by the end of the movement from affecting the stability of the entire device.

[0161] In an alternative embodiment, the moving plate is provided with a guide column 80, and the guide column 80 is provided with a magnetic positioning strip 88. The moving plate 84 is provided with a magnetic seat 89 close to the guide column 80. When the magnetic positioning strip 88 approaches the magnetic seat 89, a mutual magnetic force is generated.

[0162] In this embodiment, the magnetic positioning strip 88 is arranged on the lifting column 82 and has magnetism to generate a magnetic field at a specific position. The magnetic seat 89 is arranged on the moving plate 84 close to the guide column 80 and has magnetism to generate a mutual magnetic force with the magnetic positioning strip 88. When the lifting and feeding assembly moves in the vertical direction, the magnetic seat 89 on the moving plate 84 approaches the magnetic positioning strip 88 close to the guide column 80.

[0163] Due to the magnetic attraction between the magnetic positioning strip 88 and the magnetic seat 89, the positioning and alignment between the moving plate 84 and the guide column 80 are ensured.

[0164] The advantage of this alternative embodiment is that through the mutual attraction of the magnetic positioning strip 88 and the magnetic seat 89, accurate positioning of the lifting and feeding assembly in the vertical direction can be achieved, ensuring the movement accuracy and stability of the device. This magnetic positioning design helps to improve the working efficiency and accuracy of the device.
