Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to a component automatic buckling device and a production method of a chassis component. Background Art

[0002] In the home appliance industry, floor-standing products such as floor fans, circulation fans, tower fans, electric heaters, etc. widely use chassis components as the counterweight part of the whole machine to ensure the stability of the whole machine. The chassis assembly is usually composed of two parts: the chassis and the counterweight block. These two parts need to be tightly buckled together during the assembly process to ensure stability during use. The chassis and the counterweight block are usually buckled together by snaps, and in order to ensure that the chassis and the counterweight block are tightly buckled and not easy to separate, the number of buckle positions between the chassis and the counterweight block is usually between 3 and 6. In the traditional production process, the buckle between the chassis and the counterweight block is completed manually. That is, the worker manually buckles the chassis onto the counterweight block. This traditional manual assembly method has several significant problems. First, due to the large number of buckle positions, employees need to press the chassis vigorously and multiple times during the operation, resulting in high labor intensity, easy to cause damage to the hands, and difficult to operate, affecting 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 the scrapping of parts 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 prior art. Summary of the invention

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

[0005] An automatic fastening device for a component, the component comprising a first component and a second component which are stacked, the automatic fastening device for the component comprising:

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

[0007] A buckling station is provided at one side of the conveying line, and a lifting mechanism and a crimping mechanism are provided in the buckling station. The lifting mechanism is provided below the crimping mechanism, and the lifting mechanism includes a liftable carrying tray, and the crimping 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 load tray of the lifting mechanism will rise to an appropriate height to receive and stabilize the components on the conveyor line. After the load tray stabilizes the components, the lower pressing piece of the pressing mechanism will drop to apply pressure to the components on the load tray, so that the first component and the second component are tightly fastened together. The various mechanical parts work closely together, and through precise control and mechanical movement, uncertain factors in manual operation, such as uneven force and position deviation, can be avoided, thereby improving the fastening quality and overall quality of the product and improving 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 across 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 design of the mounting frame provides a stable support for the crimping mechanism and ensures that the relative positions between the mechanisms remain unchanged during the entire fastening process, thereby enhancing the stability of the fastening operation. The crimping drive device can be a cylinder or a push rod motor. Through the application of the automated drive device, the fastening action is fast and continuous, which greatly shortens the fastening time of a single workpiece and improves the overall production efficiency.

[0014] In a preferred technical solution of the present invention, N crimping mechanisms are arranged 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 device and a lower pressing piece, and each crimping mechanism works together according to a preset program and sequence. Since the crimping mechanism is arranged in a ring, it can simultaneously perform fastening operations on multiple workpieces on the conveyor line, or perform multi-point fastening on a single workpiece, thereby greatly improving the fastening efficiency and processing capacity.

[0017] The ring-shaped crimping mechanism can fasten the workpiece from multiple directions, ensuring the uniformity and consistency of the fastening and improving the fastening quality.

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 snap-fitting action is about to be completed. The first buffer is usually made of a material with good elasticity and shock absorption performance, 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 and 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 penetrate the mounting plate.

[0022] A mounting plate is provided on the conveyor line to provide a stable support for the jacking mechanism. The jacking drive device can be implemented by a cylinder, a hydraulic cylinder or an electric push rod, and the jacking drive device is firmly fixed on the mounting plate. Its output end is arranged toward the crimping mechanism so that the workpiece can be jacked to a position matching the crimping mechanism when needed.

[0023] As a key component for transmitting force in the jacking mechanism, the connecting plate is fixed to the output end of the jacking drive device. 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 rod guides and stabilizes the movement of the connecting plate. The existence of the guide rod 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 coordination 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 at the edges of the connecting plate; a guide cylinder is provided on the mounting plate, and one end of the guide rod passes through the guide cylinder;

[0027] A limiting ring is arranged 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] On the mounting plate, a guide cylinder is arranged at a position corresponding to the guide rod. This design not only provides a more stable support for the guide rod, but also ensures the smoothness and stability of the guide rod during movement. 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 limiting ring protrudes outward from the outer wall of the guide rod, and 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 back 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 arranged between the carrying tray and the connecting plate;

[0032] A rotation driving device is arranged on the carrying tray, and a limiting member is arranged at the output end of the rotation driving device, and the limiting member is used for clamping with the component to be assembled.

[0033] Specifically, in order to ensure that the load tray can smoothly contact and separate the components during the lifting and falling process, a second buffer is provided between the load tray and the connecting plate. The second buffer is made of a material with good elasticity and shock absorption performance, such as rubber, sponge or spring. Its function is to absorb the impact force between the load tray and the connecting plate, reduce rigid collision, and thus protect the components to be assembled from damage.

[0034] A rotation drive device is provided on the carrier tray. The rotation drive device may be a servo motor, and a limiter is provided at its output end. The limiter is used to engage with the component to be assembled to ensure that the component can maintain the correct position and posture during the assembly process.

[0035] In a preferred technical solution of the present invention, it further includes a first blocking structure and a second blocking structure; 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;

[0036] In-place sensors are provided at the entrance and 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 arranged upstream of the fastening station and is used to block and position the workpiece before it enters the fastening station. The first blocking structure includes a blocking cylinder and a blocking part. The blocking cylinder is fixed below the conveyor line and drives the movement of the blocking part through the telescopic movement of its piston rod. The roller group of the blocking part consists of two rollers arranged opposite to each other, which rotate with the blocking bracket and can roll when the workpiece contacts, 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-place sensors are provided at the entrance and exit of the fastening station. The in-place sensors are used to detect whether the workpiece has reached the predetermined position, thereby triggering the corresponding control signal to make the blocking structure work in coordination so that the workpiece enters or leaves the fastening station.

[0042] A second object of the present invention is to provide a method for producing a chassis assembly, wherein the chassis assembly includes a first component and a second component, wherein the first component is arranged on the second component, and during the assembly process, the first component and the second component are fastened together using the automatic fastening device for the assembly as described above.

[0043] Specifically, the first component is a chassis, the second component is a counterweight, and a buckle that engages with each other is provided between the chassis and the counterweight. After being pressed by the automatic buckling device of the assembly, the buckles between the two components are locked with each other, thereby achieving a tight combination between the chassis and the counterweight.

The bearing tray is used to receive the component, and the bearing tray and the lower pressing member move relative to each other to achieve the pressing of the component. During the use of the device, the conveyor line conveys the stacked first component and the second component (i.e., the component to be assembled) to the fastening station. In the fastening station, the bearing tray of the lifting mechanism will rise to an appropriate height to receive and stabilize the component on the conveyor line, and when the bearing tray stabilizes the component, the lower pressing member of the crimping mechanism will descend to apply pressure to the component on the bearing tray, so that the first component and the second component are tightly fastened together. When the components are successfully pressed together, the lower pressing piece will rise back to the initial position, and the carrying tray will also drop, placing the pressed components back on the conveyor line, which will then deliver the pressed components.

[0057] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the 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. On the contrary, 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.

[0058] In the home appliance industry, floor-standing products such as floor fans, circulation fans, tower fans, electric heaters, etc. widely use chassis components as the counterweight part of the whole machine to ensure the stability of the whole machine. The chassis assembly is usually composed of two parts: the chassis and the counterweight block. These two parts need to be tightly buckled together during the assembly process to ensure stability during use. The chassis and the counterweight block are usually buckled together by snaps, and in order to ensure that the chassis and the counterweight block are tightly buckled and not easy to separate, the number of buckle positions between the chassis and the counterweight block is usually between 3 and 6. In the traditional production process, the buckle between the chassis and the counterweight block is completed manually. That is, the worker manually buckles the chassis onto the counterweight block. This traditional manual assembly method has several significant problems. First, due to the large number of buckle positions, employees need to press the chassis vigorously and multiple times during the operation, resulting in high labor intensity, easy to cause damage to the hands, and difficult to operate, affecting 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 the scrapping of parts and increasing production costs.

[0059] The rotation process is unstable, resulting in abnormal noise and vibration of the compressor, which seriously affects the customer experience.

[0060] Based on this, the present application provides an automatic fastening device for components.

[0061] Example 1

[0062] like Figure 1-Figure 8 As shown, this embodiment provides an automatic fastening device for components, wherein the component 2 includes a first component and a second component which are stacked, and is characterized in that the automatic fastening device for components includes:

[0063] A conveyor line 1, wherein the conveyor line 1 is used to convey components 2 to be assembled;

[0064] A fastening station 100 is provided at one side of the conveyor line 1. A lifting mechanism 5 and a crimping mechanism 4 are provided in the fastening station 100. The lifting mechanism 5 is provided below the crimping mechanism 4. The lifting mechanism 5 includes a liftable carrying tray 54. The crimping mechanism 4 includes a liftable lower pressing member 42.

[0065] The carrying tray 54 is used to receive the component 2 , and the carrying tray 54 and the pressing member 42 move relative to each other to achieve pressing of the component 2 .

[0066] During use, the device automatically conveys the components 2 to be assembled via the conveyor line 1, thereby 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.

[0067] The automatic snap-fitting 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 snap-fitting device so that the chassis and the counterweight block are snap-fitted and locked to each other, thereby effectively saving the production time of the chassis assembly 2.

[0068] During the pressing process, the supporting tray 54 of the lifting mechanism 5 will rise to an appropriate height to receive and stabilize the component 2 on the conveyor line 1. After the supporting tray 54 stabilizes the component 2, the pressing member 42 of the crimping mechanism 4 descends to apply pressure to the component 2 on the supporting tray 54, so that the first component and the second component are tightly fastened together. The various mechanical parts are closely matched, and through precise control and mechanical movement, uncertain factors in manual operation, such as uneven force and position deviation, can be avoided, thereby improving the fastening quality and overall quality of the product and improving production efficiency.

[0069] In this embodiment, a mounting frame 3 is provided at the fastening station 100, the mounting frame 3 spans across 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;

[0070] 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 .

[0071] The design of the mounting frame 3 provides a stable support for the crimping mechanism 4 and ensures that the relative positions between the mechanisms remain unchanged during 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 application of the automated drive device, the fastening action is fast and continuous, which greatly shortens the fastening time of a single workpiece, thereby improving the overall production efficiency.

[0072] Example 2

[0073] like Figure 1-Figure 8 As shown, this embodiment is improved on the basis of embodiment 1.

[0074] In this embodiment, N crimping mechanisms 4 are arranged on the mounting frame 3, and the N crimping mechanisms 4 are arranged in a ring shape on the mounting frame 3;

[0075] 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 crimping mechanisms 4 are provided, and a force is applied to the chassis through multiple crimping mechanisms 4, so that the chassis can be effectively buckled on the counterweight.

[0076] In a specific embodiment, each crimping mechanism 4 is independently equipped with a crimping drive device 41 and a lower pressing member 42, and each crimping mechanism 4 works in coordination according to a preset program and sequence. Since the crimping mechanism 4 is arranged in a ring shape, it can simultaneously perform a fastening operation on multiple workpieces on the conveyor line 1, or perform multi-point fastening on a single workpiece, thereby greatly improving the fastening efficiency and processing capacity.

[0077] The annular crimping mechanism 4 can buckle the workpiece from multiple directions, ensuring the uniformity and consistency of the buckling and improving the buckling quality. At the same time, the simultaneous existence of multiple crimping points also helps to reduce quality problems caused by single-point buckling.

[0078] 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 driving device 41 , and the first buffer member 422 is detachably connected to the pressing hammer 421 .

[0079] As the main component that directly performs the snap-fitting action, the pressure hammer 421 can be made of a material with high hardness and good wear resistance to ensure that sufficient pressure can be transmitted during the snap-fitting 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 buffer and vibration reduction effect for the pressure hammer 421 when the snap-fitting action is about to be completed. The first buffer member 422 is usually made of a material with good elasticity and shock absorption performance, 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.

[0080] Example 3

[0081] like Figure 1-Figure 8 As shown, this embodiment is improved on the basis of embodiment 1.

[0082] In this embodiment, an implementation of the lifting mechanism 5 is provided, which is specifically as follows:

[0083] 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 on the mounting plate 11, and the output end of the lifting drive device 51 is arranged toward the crimping mechanism 4, and the connecting plate 56 is fixed to the output end of the lifting drive device 51;

[0084] One end of the guide rod 52 is fixedly connected to the connecting plate 56 , and the other end thereof penetrates through the mounting plate 11 .

[0085] A mounting plate 11 is provided on the conveyor line 1 to provide a stable support for the lifting mechanism 5. The lifting drive device 51 can be implemented by a cylinder, a hydraulic cylinder or an electric push rod, and the lifting drive device 51 is firmly fixed on the mounting plate 11. Its output end is arranged toward the crimping mechanism 4 so as to lift the workpiece to a position matching the crimping mechanism 4 when needed.

[0086] The connecting plate 56, as a key component for transmitting force in the jacking mechanism 5, 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 a stable shape and performance can be maintained during the jacking process.

[0087] The guide rod 52 plays a role in guiding and stabilizing 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 track during the lifting and falling process, avoiding errors and damages caused by deviation or shaking.

[0088] 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.

[0089] In a more preferred implementation of this embodiment, the guide rods 52 are provided in M ​​pieces, and the M guide rods 52 are respectively provided at 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 passes through the guide cylinder 111;

[0090] A limiting ring 521 is disposed 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 .

[0091] 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, further improving the lifting accuracy and stability.

[0092] Specifically, the cross section of the connecting plate 56 is rectangular, and 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 .

[0093] 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 the smoothness and stability of the guide rod 52 during movement. The guide cylinder 111 can be made of wear-resistant and corrosion-resistant materials to ensure its performance and accuracy under long-term use.

[0094] The limiting ring 521 protrudes outward from the outer wall of the guide rod 52, and 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.

[0095] Example 4

[0096] like Figure 1-Figure 8 As shown, this embodiment is improved on the basis of embodiment 3.

[0097] 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 ;

[0098] 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.

[0099] Specifically, in order to ensure that the carrying tray 54 can smoothly contact and separate the components 2 during the lifting and falling process, a second buffer 53 is provided between the carrying tray 54 and the connecting plate 56. The second buffer 53 is made of a material with good elasticity and shock absorption performance, such as rubber, sponge or spring. Its function is to absorb the impact force between the carrying tray 54 and the connecting plate 56, reduce rigid collision, and thus protect the components 2 to be assembled from damage.

[0100] A rotation drive device 55 is provided on the carrier tray 54. The rotation drive device 55 may be a servo motor, and a limiter 551 is provided at its output end. The limiter 551 is used to engage with the assembly 2 to be assembled, so as to ensure that the assembly 2 can maintain the correct position and posture during the assembly process. By driving the rotation drive device 55, the limiter 551 can drive the assembly 2 to rotate, thereby achieving precise assembly alignment.

[0101] In practical applications, the automatic fastening device of the components of the present application is used in the production process of the chassis component 2 to achieve the 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 the fastening positions are fully fastened in place. In this embodiment, a rotation drive device 55 is set to drive the chassis component 2 to rotate. Through the secondary press after rotation, the fastening positions that were not fully pressed or in an unfavorable position in the first press can be given the opportunity to be pressed again, thereby ensuring that each fastening position can obtain a uniform and effective pressing force to achieve comprehensive fastening. Moreover, during the pressing process, the contact surface between the chassis and the counterweight may be uneven or have a small gap due to factors such as material properties and manufacturing errors. A single press may not be able to completely eliminate these gaps, resulting in 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 surface fit more closely, thereby improving the fastening quality and the overall stability of the product.

[0102] In addition, there are many types of floor-standing products in the home appliance industry, and the structures and sizes of chassis and counterweights are different. By designing a secondary pressing mechanism after rotation, it is possible to adapt to the assembly requirements of different product structures without changing the basic equipment structure, and realize flexible automated production.

[0103] Example 5

[0104] like Figure 1-Figure 8 As shown, this embodiment is improved on the basis of embodiment 1.

[0105] In this embodiment, a first blocking structure 6 and a second blocking structure 7 are further included; along the conveying direction of the conveying 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;

[0106] Arrival sensors 8 are provided at the entrance and exit of the fastening station 100 .

[0107] In this embodiment, the first blocking structure 6 includes a blocking cylinder 61 and a blocking portion, wherein 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;

[0108] The blocking portion 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.

[0109] 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 includes a blocking cylinder 61 and a blocking part. The blocking cylinder 61 is fixed below the conveyor line 1, and drives the movement of the blocking part through the telescopic movement of its piston rod. The roller group 63 of the blocking part is composed of two roller groups 63 arranged opposite to each other, which are rotatably matched with the blocking bracket 62, and can roll when the workpiece contacts, thereby reducing friction and damage to the workpiece.

[0110] 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 the first blocking structure 6, and can also be appropriately adjusted according to actual needs.

[0111] At the same time, in-place sensors 8 are provided at the entrance and exit of the fastening station 100. The in-place sensors 8 are used to detect whether the workpiece has reached a predetermined position, thereby triggering a corresponding control signal so that the blocking structure works in coordination so that the workpiece enters or leaves the fastening station 100. The in-place sensors 8 can be implemented by photoelectric sensors.

[0112] In practical applications, a plurality of the first blocking structure 6 and the second blocking structure 7 can be provided to effectively limit the position of the workpiece.

[0113] Example 6

[0114] like Figure 1-Figure 8 As shown, this embodiment is improved on the basis of embodiment 1.

[0115] This embodiment provides a method for producing a chassis assembly, wherein the chassis assembly includes a first component and a second component, wherein the first component is arranged on the second component, and during the assembly process, the first component and the second component are fastened together using the automatic fastening device for components as described above.

[0116] Specifically, in the chassis assembly, the first component is the chassis, the second component is the counterweight, and a buckle that engages with each other is provided between the chassis and the counterweight. After being pressed by the automatic buckling device of the assembly, the buckles between the two components are locked with each other, thereby achieving a tight combination between the chassis and the counterweight.

[0117] In this embodiment, the production method is used to produce the chassis assembly 2, and the specific production process is as follows:

[0118] Placing the counterweight and the chassis on the conveyor line 1, wherein the chassis is placed on the counterweight;

[0119] The conveyor line 1 is started, and the counterweight and chassis are sent to the fastening station 100; when the in-position sensor 8 upstream of the fastening station 100 detects that the counterweight and chassis have passed, a signal is sent to the control system of the device, and the control system controls the second blocking structure 7 to start, so that the second blocking structure 7 rises. The second blocking structure 7 limits the counterweight and chassis in the fastening station 100. At this time, after the in-position sensor 8 in the fastening station 100 detects that the counterweight and chassis are in place, a signal is sent to the control system of the device, and the control system controls the first blocking structure 6 to start, so as to prevent the subsequent counterweight and chassis from entering the fastening station 100, so as not to affect the fastening process.

[0120] The lifting mechanism 5 and the crimping mechanism 4 work together to make the chassis and the counterweight tightly buckled with each other. The chassis assembly 2 after buckling 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 by the conveyor line 1.

[0121] Then the first blocking structure 6 descends, and the subsequent chassis component enters the fastening station 100 to perform the fastening process of the next chassis component 2 .

[0122] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying 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.

[0123] 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.

[0124] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
