Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic fastening device for components. Background Art

[0002] In the home appliance industry, floor-standing products such as floor fans, circulation fans, tower fans, and electric heaters widely utilize chassis assemblies as the counterweight for the entire unit to ensure stability. Chassis assemblies typically consist of two parts: a chassis and a counterweight. These two parts must be tightly fastened together during assembly to ensure stability during use. The chassis and counterweight are typically fastened together using snaps. To ensure a tight fit and prevent separation, the number of snaps between the chassis and counterweight is typically between three and six. Traditionally, the fastening of the chassis and counterweight is performed manually, with workers manually pressing the chassis onto the counterweight. This traditional manual assembly method presents several significant issues. First, due to the numerous snaps, workers must apply multiple, forceful pressure to the chassis during operation, resulting in high labor intensity, hand injuries, and operational difficulty, which impacts production efficiency. Secondly, due to the limitations of manual operation, it is easy for buckles to be missed or not fastened properly during the fastening process, which not only affects the assembly quality of the product, but may also cause the chassis to fall out, resulting in parts scrapping and increasing production costs.

[0003] Therefore, it is necessary to improve the production method of the existing chassis components to overcome the defects of the existing technology. Utility Model Content

[0004] In order to overcome the problems existing in the related art, the purpose of the present invention is to provide an automatic fastening device for components, which can realize the mutual fastening of different components, reduce the degree of manual participation, and the mechanized fastening method can better ensure the accuracy and consistency of the fastening compared to manual operation, thereby improving the fastening quality and overall quality of the product.

[0005] An automatic fastening device for an assembly, wherein the assembly includes a first component and a second component that are stacked, and the automatic fastening device for the assembly includes:

[0006] A conveyor line, the conveyor line is used to convey components to be assembled;

[0007] A fastening station is provided on one side of the conveyor line, wherein the fastening station is provided with a lifting mechanism and a pressing mechanism, wherein the lifting mechanism is provided below the pressing mechanism, the lifting mechanism includes a liftable carrying tray, and the pressing mechanism includes a liftable lower pressing member;

[0008] The carrying tray is used to receive the components, and the carrying tray and the pressing member move relative to each other to achieve pressing of the components.

[0009] During use, the device automatically transports components to be assembled through a conveyor line, realizing an automated production process. When pressing different parts of the components together, no human intervention is required, which reduces the labor intensity of workers and improves the comfort of the working environment.

[0010] During the pressing process, the lifting mechanism's carrier tray rises to the appropriate height to receive and stabilize the component on the conveyor line. Once the carrier tray stabilizes the component, the pressing mechanism's lowering element descends, applying pressure to the component on the carrier tray, tightly fastening the first and second components together. The tight coordination between the various mechanical components, through precise control and mechanical movement, eliminates uncertainties associated with manual operation, such as uneven force and positional deviations, thereby improving both the fastening quality and overall product quality, and enhancing production efficiency.

[0011] In a preferred technical solution of the present invention, a mounting frame is provided at the fastening station, the mounting frame spans the conveyor line, the crimping mechanism is provided on the mounting frame, and the lifting mechanism is provided below the mounting frame;

[0012] The crimping mechanism includes a crimping drive device and a pressing member. The crimping drive device is fixed on the mounting frame, and the output end of the crimping drive device is arranged toward the lifting mechanism. The pressing member is arranged at the output end of the crimping drive device.

[0013] The mounting bracket design provides a stable support for the crimping mechanism and ensures that the relative positions of the mechanisms remain unchanged throughout the entire fastening process, thereby enhancing the stability of the fastening operation. The crimping drive device can be a pneumatic cylinder or a push rod motor. Through the use of an automated drive device, the fastening action is fast and continuous, significantly reducing the fastening time of a single workpiece and thereby improving overall production efficiency.

[0014] In a preferred technical solution of the present utility model, N crimping mechanisms are provided on the mounting frame, and the N crimping mechanisms are arranged in a ring shape on the mounting frame;

[0015] Wherein, N is a natural number greater than 2.

[0016] Each crimping mechanism is independently equipped with a crimping drive and a lower pressure element, and they work together according to a pre-set program and sequence. Because the crimping mechanisms are arranged in a ring, they can simultaneously fasten multiple workpieces on a conveyor line, or perform multi-point fastening on a single workpiece, greatly improving fastening efficiency and processing capacity.

[0017] The ring-shaped crimping mechanism can fasten the workpiece from multiple directions, ensuring uniformity and consistency of the fastening and improving the fastening quality. At the same time, the simultaneous existence of multiple crimping points also helps to reduce quality problems caused by a weak single-point fastening.

[0018] In a preferred technical solution of the present invention, the pressing member includes a pressing hammer and a first buffer member. The pressing hammer is fixed to the output end of the crimping drive device, and the first buffer member is detachably connected to the pressing hammer.

[0019] As the main component that directly performs the fastening action, the pressure hammer can be made of a material with high hardness and good wear resistance to ensure that sufficient pressure can be transmitted during the fastening process and maintain a stable shape and performance. The first buffer is detachably connected to the pressure hammer. The purpose of this design is to provide a buffer and vibration reduction effect for the pressure hammer when the fastening action is about to be completed. The first buffer is usually made of a material with good elasticity and shock absorption properties, such as rubber, polyurethane, etc. When the pressure hammer contacts the workpiece and applies pressure, the first buffer can absorb part of the impact force, reduce the rigid collision between the workpiece and the pressure hammer, thereby protecting the workpiece from damage and extending the service life of the pressure hammer.

[0020] In a preferred technical solution of the present invention, the jacking mechanism includes a jacking drive device, a connecting plate and a guide rod. The conveyor line is provided with a mounting plate, the jacking drive device is fixed on the mounting plate, and the output end of the jacking drive device is arranged toward the crimping mechanism, and the connecting plate is fixed to the output end of the jacking drive device;

[0021] One end of the guide rod is fixedly connected to the connecting plate, and the other opposite end is arranged to pass through the mounting plate.

[0022] A mounting plate is installed on the conveyor line, providing stable support for the lifting mechanism. The lifting drive, which can be implemented using a pneumatic cylinder, hydraulic cylinder, or electric push rod, is securely fixed to the mounting plate. Its output end is positioned toward the crimping mechanism, enabling it to lift the workpiece to a position compatible with the crimping mechanism when needed.

[0023] The connecting plate is a key component in transmitting force in the jacking mechanism and is fixed to the output end of the jacking drive. The connecting plate can be made of high-strength and high-rigidity materials to ensure that it can maintain a stable shape and performance during the jacking process.

[0024] The guide rods guide and stabilize the movement of the connecting plate. The existence of the guide rods ensures that the connecting plate can move along the predetermined trajectory during the lifting and lowering process, avoiding errors and damage caused by deviation or shaking.

[0025] The jacking drive device works in conjunction with the connecting plate and the guide rod to form a stable jacking mechanism, which can ensure that the workpiece is stably jacked and held during the fastening process, thereby enhancing the stability of the fastening operation.

[0026] In a preferred technical solution of the present invention, the guide rods are provided in M ​​numbers, and the M guide rods are respectively provided on the edge of the connecting plate; the mounting plate is provided with a guide cylinder, and one end of the guide rod is provided through the guide cylinder;

[0027] A limiting ring is provided at one end of the guide rod away from the connecting plate, and the limiting ring protrudes outward from the outer wall of the guide rod.

[0028] In this embodiment, the number of guide rods is M, and such a design enables the connecting plate to be guided more evenly and stably during the lifting and lowering process, thereby further improving the lifting accuracy and stability.

[0029] A guide cylinder is installed on the mounting plate, corresponding to the guide rod. This design not only provides a more stable support for the guide rod, but also ensures smooth and stable movement of the guide rod. The guide cylinder can be made of wear-resistant and corrosion-resistant materials to ensure its performance and accuracy under long-term use.

[0030] The limit ring protrudes outward from the outer wall of the guide rod. Its function is to limit the movement range of the guide rod to prevent it from excessively extending or retracting during the jacking or falling process, thereby protecting the safety of the jacking mechanism and the workpiece.

[0031] In a preferred technical solution of the present invention, the carrying tray is arranged on the connecting plate, and a second buffer is provided between the carrying tray and the connecting plate;

[0032] A rotation drive device is provided on the carrying tray, and a limit piece is provided at the output end of the rotation drive device. The limit piece is used to engage with the component to be assembled.

[0033] Specifically, to ensure smooth contact and separation between the load tray and the components during the lifting and lowering process, a second buffer is placed between the load tray and the connecting plate. Made of a material with good elasticity and shock absorption, such as rubber, sponge, or spring, the second buffer absorbs the impact force between the load tray and the connecting plate, reducing rigid collisions and thus protecting the components being assembled from damage.

[0034] A rotation drive device is mounted on the carrier tray. This device can be a servo motor with a limiter at its output. The limiter engages the component to ensure it maintains the correct position and orientation during assembly. Driven by the rotation drive device, the limiter rotates the component, achieving precise assembly alignment.

[0035] In a preferred technical solution of the present invention, a first blocking structure and a second blocking structure are further included; along the conveying direction of the conveying line, the first blocking structure is arranged upstream of the fastening station, and the second blocking structure is arranged at the exit of the fastening station;

[0038] The blocking part includes a blocking bracket and a roller group, the blocking bracket is fixed on the piston rod of the blocking cylinder, and the roller group is arranged on the blocking bracket; the roller group includes two rollers arranged opposite to each other, and both of the rollers are rotatably matched with the blocking bracket.

[0039] The first blocking structure is located upstream of the fastening station and is used to block and position the workpiece before it enters the fastening station. It consists of a blocking cylinder and a blocking portion. The blocking cylinder is fixed below the conveyor line, and the movement of its piston rod drives the movement of the blocking portion. The blocking portion's roller assembly consists of two opposing rollers that rotate in conjunction with the blocking bracket, generating rolling motion when the workpiece contacts it, thereby reducing friction and damage to the workpiece.

[0040] The second blocking structure is arranged at the exit of the fastening station and is used to position the second blocking structure when the workpiece is fastened. The specific structure and working principle of the second blocking structure can be the same as those of the first blocking structure, and can also be appropriately adjusted according to actual needs.

[0041] At the same time, in-position sensors are installed at the entrance and exit of the fastening station. They detect whether the workpiece has reached the predetermined position, thereby triggering the corresponding control signal, making the blocking structure work in conjunction, so that the workpiece can enter or exit the fastening station.

[0042] The beneficial effects of the utility model are:

[0043] The utility model provides an automatic fastening device for components, which includes a first component and a second component arranged in a stacked manner. The device includes a conveyor line for conveying components to be assembled, a fastening station is provided on one side of the conveyor line, and a lifting mechanism and a pressing mechanism are provided in the fastening station. The lifting mechanism is provided below the pressing mechanism, and the lifting mechanism includes a liftable carrying tray, and the pressing mechanism includes a liftable pressing member. The carrying tray is used to receive the components, and the carrying tray and the pressing member move relative to each other to achieve the pressing of the components. During use of the device, the conveyor line conveys the stacked first component and the second component (i.e., the components to be assembled) to the fastening station. In the fastening station, the carrying tray of the lifting mechanism will rise to an appropriate height to receive and stabilize the components on the conveyor line. After the carrying tray stabilizes the components, the pressing member of the pressing mechanism descends, applying pressure to the components on the carrying tray, so that the first component and the second component are tightly fastened together. Once the components are successfully pressed together, the lower clamp rises back to its initial position, while the carrier tray descends, placing the pressed components back onto the conveyor line, which then delivers them. This significantly reduces the need for manual operation during the entire pressing process, significantly improving production efficiency. The automatic fastening mechanism, through precise mechanical movement, eliminates uncertainties associated with manual operation, such as uneven force and positional deviations, thereby improving both the fastening quality and overall product quality.

[0054] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0055] In the home appliance industry, floor-standing products such as floor fans, circulation fans, tower fans, and electric heaters widely utilize chassis assemblies as the counterweight for the entire unit to ensure stability. Chassis assemblies typically consist of two parts: a chassis and a counterweight. These two parts must be tightly fastened together during assembly to ensure stability during use. The chassis and counterweight are typically fastened together using snaps. To ensure a tight fit and prevent separation, the number of snaps between the chassis and counterweight is typically between three and six. Traditionally, the fastening of the chassis and counterweight is performed manually, with workers manually pressing the chassis onto the counterweight. This traditional manual assembly method presents several significant issues. First, due to the numerous snaps, workers must apply multiple, forceful pressure to the chassis during operation, resulting in high labor intensity, hand injuries, and operational difficulty, which impacts production efficiency. Secondly, due to the limitations of manual operation, it is easy for buckles to be missed or not fastened properly during the fastening process, which not only affects the assembly quality of the product, but may also cause the chassis to fall out, resulting in parts scrapping and increasing production costs.

[0056] The rotation process is unstable, resulting in abnormal noise and vibration of the compressor, which seriously affects the customer experience.

[0057] Based on this, the present application provides an automatic fastening device for components.

[0058] Example 1

[0059] like Figures 1-8 As shown, this embodiment provides an automatic fastening device for components, wherein the component 2 includes a first component and a second component that are stacked, and is characterized in that the automatic fastening device for components includes:

[0060] A conveyor line 1, wherein the conveyor line 1 is used to convey components 2 to be assembled;

[0061] A fastening station 100 is provided on one side of the conveyor line 1. The fastening station 100 is provided with a lifting mechanism 5 and a pressing mechanism 4. The lifting mechanism 5 is provided below the pressing mechanism 4. The lifting mechanism 5 includes a liftable carrying tray 54. The pressing mechanism 4 includes a liftable lower pressing member 42.

[0062] The carrying tray 54 is used to receive the component 2 . The carrying tray 54 and the pressing member 42 move relative to each other to press the component 2 .

[0063] During use, the device automatically conveys the components 2 to be assembled through the conveyor line 1, realizing an automated production process. When the different parts of the components 2 are pressed together, no human intervention is required, which reduces the labor intensity of the workers and improves the comfort of the working environment.

[0064] The automatic fastening device can be used in the production process of the chassis assembly 2. The chassis and the counterweight block are pressed together by the automatic fastening device, so that the chassis and the counterweight block are fastened to each other and locked, thereby effectively saving the production time of the chassis assembly 2.

[0065] During the pressing process, the supporting tray 54 of the lifting mechanism 5 rises to an appropriate height to receive and stabilize the component 2 on the conveyor line 1. Once the supporting tray 54 has stabilized the component 2, the pressing member 42 of the pressing mechanism 4 descends, applying pressure to the component 2 on the supporting tray 54 and tightly fastening the first and second components together. The tight coordination between the various mechanical components, through precise control and mechanical movement, avoids uncertainties associated with manual operation, such as uneven force and positional deviations, thereby improving the fastening quality and overall quality of the product and enhancing production efficiency.

[0066] In this embodiment, a mounting frame 3 is provided at the fastening station 100, the mounting frame 3 spanning the conveyor line 1, the crimping mechanism 4 is provided on the mounting frame 3, and the lifting mechanism 5 is provided below the mounting frame 3;

[0067] The crimping mechanism 4 includes a crimping drive device 41 and a pressing member 42 . The crimping drive device 41 is fixed on the mounting frame 3 , and the output end of the crimping drive device 41 is arranged toward the lifting mechanism 5 . The pressing member 42 is arranged at the output end of the crimping drive device 41 .

[0068] The design of the mounting frame 3 provides a stable support for the crimping mechanism 4 and ensures that the relative positions of the mechanisms remain unchanged throughout the entire fastening process, thereby enhancing the stability of the fastening operation. The crimping drive device 41 can be a cylinder or a push rod motor. Through the use of an automated drive device, the fastening action is fast and continuous, greatly reducing the fastening time of a single workpiece and thereby improving overall production efficiency.

[0069] Example 2

[0070] like Figures 1-8 As shown, this embodiment is improved on the basis of embodiment 1.

[0071] In this embodiment, N crimping mechanisms 4 are provided on the mounting frame 3, and the N crimping mechanisms 4 are arranged in a ring shape on the mounting frame 3;

[0072] Wherein, N is a natural number greater than 2. In a specific embodiment, N is equal to 7 or 8, that is, 7 or 8 pressing mechanisms 4 are provided, and a force is applied to the chassis by multiple pressing mechanisms 4, so that the chassis can be effectively buckled on the counterweight.

[0073] In a specific embodiment, each crimping mechanism 4 is independently equipped with a crimping drive device 41 and a lower pressing member 42. Each crimping mechanism 4 works in conjunction with a preset program and sequence. Because the crimping mechanisms 4 are arranged in a ring, they can simultaneously fasten multiple workpieces on the conveyor line 1 or perform multi-point fastening on a single workpiece, thereby greatly improving fastening efficiency and processing capacity.

[0074] The annular crimping mechanism 4 can fasten the workpiece from multiple directions, ensuring uniformity and consistency of the fastening and improving the fastening quality. At the same time, the simultaneous existence of multiple crimping points also helps to reduce quality problems caused by weak single-point fastening.

[0075] In a more specific implementation of this embodiment, the lower pressing member 42 includes a pressing hammer 421 and a first buffer member 422 . The pressing hammer 421 is fixed to the output end of the crimping drive device 41 , and the first buffer member 422 is detachably connected to the pressing hammer 421 .

[0076] The pressure hammer 421, as the main component that directly performs the fastening action, can be made of a material with high hardness and good wear resistance to ensure that sufficient pressure can be transmitted during the fastening process and maintain a stable shape and performance. The first buffer member 422 is detachably connected to the pressure hammer 421. The purpose of this design is to provide a buffering and vibration reduction effect for the pressure hammer 421 when the fastening action is about to be completed. The first buffer member 422 is usually made of a material with good elasticity and shock absorption properties, such as rubber, polyurethane, etc. When the pressure hammer 421 contacts the workpiece and applies pressure, the first buffer member 422 can absorb part of the impact force, reduce the rigid collision between the workpiece and the pressure hammer 421, thereby protecting the workpiece from damage and extending the service life of the pressure hammer 421.

[0077] Example 3

[0078] like Figures 1-8 As shown, this embodiment is improved on the basis of embodiment 1.

[0079] In this embodiment, an implementation of the lifting mechanism 5 is provided, which is specifically as follows:

[0080] The lifting mechanism 5 includes a lifting drive device 51, a connecting plate 56 and a guide rod 52. The conveyor line 1 is provided with a mounting plate 11. The lifting drive device 51 is fixed to the mounting plate 11, and the output end of the lifting drive device 51 is arranged toward the crimping mechanism 4. The connecting plate 56 is fixed to the output end of the lifting drive device 51.

[0081] One end of the guide rod 52 is fixedly connected to the connecting plate 56 , and the other end thereof passes through the mounting plate 11 .

[0082] A mounting plate 11 is provided on the conveyor line 1, providing stable support for the lifting mechanism 5. A lifting drive device 51, which can be implemented using a pneumatic cylinder, hydraulic cylinder, or electric push rod, is securely fixed to the mounting plate 11. Its output end faces the crimping mechanism 4, enabling it to lift the workpiece to a position that matches the crimping mechanism 4 when needed.

[0083] The connecting plate 56 is a key component for transmitting force in the jacking mechanism 5 and is fixed to the output end of the jacking drive device 51. The connecting plate 56 can be made of a material with high strength and good rigidity to ensure that it can maintain a stable shape and performance during the jacking process.

[0084] The guide rod 52 guides and stabilizes the movement of the connecting plate 56. The existence of the guide rod 52 ensures that the connecting plate 56 can move along a predetermined trajectory during the lifting and lowering process, avoiding errors and damage caused by deviation or shaking.

[0085] The jacking drive device 51 cooperates with the connecting plate 56 and the guide rod 52 to form a stable jacking mechanism 5, which can ensure that the workpiece is stably jacked and held during the fastening process, thereby enhancing the stability of the fastening operation.

[0086] In a more preferred embodiment of this embodiment, the guide rods 52 are provided in M ​​pieces, and the M guide rods 52 are respectively provided on the edges of the connecting plate 56; a guide cylinder 111 is provided on the mounting plate 11, and one end of the guide rod 52 is provided through the guide cylinder 111;

[0087] A limiting ring 521 is provided at one end of the guide rod 52 away from the connecting plate 56 , and the limiting ring 521 protrudes outward from the outer wall of the guide rod 52 .

[0088] In this embodiment, the number of guide rods 52 is M, and such a design enables the connecting plate 56 to be guided more evenly and stably during the lifting and lowering process, thereby further improving the lifting accuracy and stability.

[0089] Specifically, if the cross section of the connecting plate 56 is rectangular, four guide rods 52 may be provided, and the four guide rods 52 are respectively fixedly connected to the four corners of the connecting plate 56 , thereby achieving a stable guiding effect for the movement of the connecting plate 56 .

[0090] A guide cylinder 111 is provided on the mounting plate 11 at a position corresponding to the guide rod 52. This design not only provides a more stable support for the guide rod 52 but also ensures smoothness and stability during the movement of the guide rod 52. The guide cylinder 111 can be made of wear-resistant and corrosion-resistant materials to ensure its performance and accuracy under long-term use.

[0091] The limiting ring 521 protrudes outward from the outer wall of the guide rod 52. Its function is to limit the movement range of the guide rod 52 to prevent it from excessively extending or retracting during the lifting or falling process, thereby protecting the safety of the lifting mechanism 5 and the workpiece.

[0092] Example 4

[0093] like Figures 1-8 As shown, this embodiment is improved on the basis of embodiment 3.

[0094] In this embodiment, the carrying tray 54 is disposed on the connecting plate 56 , and a second buffer member 53 is disposed between the carrying tray 54 and the connecting plate 56 ;

[0095] The carrying tray 54 is provided with a rotation driving device 55 , and an output end of the rotation driving device 55 is provided with a limiting member 551 , and the limiting member 551 is used for engaging with the component 2 to be assembled.

[0096] Specifically, to ensure that the carrier tray 54 can smoothly contact and separate from the component 2 during the lifting and lowering processes, a second buffer member 53 is provided between the carrier tray 54 and the connecting plate 56. The second buffer member 53 is made of a material with good elasticity and shock absorption properties, such as rubber, sponge, or spring. Its function is to absorb the impact force between the carrier tray 54 and the connecting plate 56, reducing rigid collisions and thus protecting the component 2 to be assembled from damage.

[0097] A rotation drive device 55 is mounted on the carrier tray 54. This device can be a servo motor, with a limiter 551 located at its output. This limiter 551 engages with the component 2 to be assembled, ensuring that the component 2 maintains its correct position and orientation during assembly. Driven by the rotation drive 55, the limiter 551 rotates the component 2, achieving precise assembly alignment.

[0098] In actual applications, the automatic component fastening device of the present application is used in the production process of the chassis assembly 2 to achieve mutual fastening of the chassis and the counterweight. Since the number of fastening positions between the chassis and the counterweight may be large and distributed in different positions, a single press may not ensure that all fastening positions are fully fastened in place. In this embodiment, a rotation drive device 55 is provided to drive the chassis assembly 2 to rotate. Through the secondary press after rotation, the fastening positions that were not fully pressed or were in an unfavorable position during the initial press can be given the opportunity to be pressed again, thereby ensuring that each fastening position can receive a uniform and effective pressing force, achieving comprehensive fastening. In addition, during the press process, the contact surface between the chassis and the counterweight may be uneven or have small gaps due to factors such as material properties and manufacturing errors. A single press may not be able to completely eliminate these gaps, resulting in a loose fastening or a risk of loosening. Through the secondary press after rotation, the pressing forces in different directions can be used to make the contact surfaces fit more tightly, improving the fastening quality and the overall stability of the product.

[0099] Furthermore, the home appliance industry boasts a wide variety of floor-standing products, with varying chassis and counterweight structures and sizes. By designing a post-rotation secondary pressing mechanism, we can adapt to the assembly requirements of diverse product structures without changing the basic equipment structure, enabling flexible automated production.

[0102] In this embodiment, a first blocking structure 6 and a second blocking structure 7 are further included; along the conveying direction of the conveyor line 1, the first blocking structure 6 is arranged upstream of the fastening station 100, and the second blocking structure 7 is arranged at the exit of the fastening station 100;

[0103] In-place sensors 8 are provided at the entrance and exit of the fastening station 100 .

[0104] In this embodiment, the first blocking structure 6 includes a blocking cylinder 61 and a blocking portion. The blocking cylinder 61 is fixed below the conveying line 1, and the blocking portion is fixed on the piston rod of the blocking cylinder 61.

[0105] The blocking part includes a blocking bracket 62 and a roller set 63. The blocking bracket 62 is fixed on the piston rod of the blocking cylinder 61, and the roller set 63 is arranged on the blocking bracket 62; the roller set 63 includes two rollers arranged opposite to each other, and both of the rollers are rotatably matched with the blocking bracket 62.

[0106] The first blocking structure 6 is arranged upstream of the fastening station 100 and is used to block and position the workpiece before it enters the fastening station 100. The first blocking structure 6 comprises a blocking cylinder 61 and a blocking portion. The blocking cylinder 61 is fixed below the conveyor line 1 and drives the movement of the blocking portion through the telescopic movement of its piston rod. The roller assembly 63 of the blocking portion is composed of two roller assemblies 63 arranged opposite to each other. They rotate in conjunction with the blocking bracket 62 and can roll when the workpiece contacts the workpiece, thereby reducing friction and damage to the workpiece.

[0107] The second blocking structure 7 is arranged at the exit of the fastening station 100, and is used to position the second blocking structure 7 when the workpiece is fastened. The specific structure and working principle of the second blocking structure 7 can be the same as those of the first blocking structure 6, and can also be appropriately adjusted according to actual needs.

[0108] At the same time, in-position sensors 8 are provided at both the entrance and exit of the fastening station 100. These in-position sensors 8 detect whether the workpiece has reached a predetermined position, thereby triggering corresponding control signals to cause the blocking structure to cooperate, allowing the workpiece to enter or exit the fastening station 100. In-position sensors 8 can be implemented as photoelectric sensors.

[0109] In practical applications, a plurality of the first blocking structures 6 and the second blocking structures 7 can be provided to effectively limit the workpiece.

[0110] Example 6

[0111] like Figures 1-8 As shown, this embodiment is improved on the basis of embodiment 1.

[0112] This embodiment provides a method for producing a chassis assembly, wherein the assembly 2 includes a first component and a second component, wherein the first component is arranged on the second component. During the assembly process, the first component and the second component are fastened together based on the automatic fastening device of the assembly as described above.

[0113] The assembly 2 may be a chassis assembly 2, wherein the first component is the chassis and the second component is the counterweight. A buckle is provided between the chassis and the counterweight for interlocking. After being pressed by the assembly's automatic buckling device, the buckle between the two components is locked together, thereby achieving a tight connection between the chassis and the counterweight.

[0114] In this embodiment, the chassis assembly 2 includes a chassis and a counterweight. The specific production process is as follows:

[0115] Place the counterweight and chassis on the conveyor line 1, wherein the chassis is placed on the counterweight;

[0116] Conveyor line 1 starts, feeding the counterweight and chassis into the fastening station 100. When the in-position sensor 8 upstream of the fastening station 100 detects the passage of the counterweight and chassis, it sends a signal to the device's control system, which activates the second blocking structure 7, causing it to rise. The second blocking structure 7 holds the counterweight and chassis in place within the fastening station 100. At this point, the in-position sensor 8 within the fastening station 100 detects that the counterweight and chassis are in place and sends a signal to the device's control system, which activates the first blocking structure 6 to prevent subsequent counterweights and chassis from entering the fastening station 100, thereby preventing them from interfering with the fastening process.

[0117] The lifting mechanism 5 and the crimping mechanism 4 work together to tightly fit the chassis and the counterweight. The chassis assembly 2, which has been fastened, is driven by the lifting mechanism 5 and returns to the conveyor line 1. At this time, the second blocking structure 7 descends and the chassis assembly 2 is sent out of the conveyor line 1.

[0118] Then the first blocking structure 6 descends, and the subsequent chassis assembly enters the fastening station 100 to perform the fastening process of the next chassis assembly 2 .

[0119] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0120] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0121] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
