Description

Technical Field

[0001] This utility model relates to the field of integrated device technology, and in particular to an automatic assembly and welding device. Background Technology

[0002] In the fields of electronic components and precision parts manufacturing, the assembly of the center cover spring is a critical process affecting product performance and long-term quality. Because the assembled center cover spring needs to form a stable fit with other components (such as the center cover plate and center wall plate), the gap between the riveted components and the center cover plate after assembly must be strictly controlled to ≤0.03mm. Otherwise, loosening of the components after long-term use can easily occur, directly affecting product reliability. Therefore, this process has extremely high requirements for assembly accuracy, stability, and process efficiency.

[0003] In existing technologies, the assembly of the middle cover spring requires manual labor. After assembly, bending and other operations are performed using equipment, followed by manual inspection to ensure it meets usage requirements. However, this method involves excessive manual intervention, and the force applied during assembly of the middle cover and spring is inconsistent, leading to problems such as loosening after assembly. Furthermore, manual assembly reduces production efficiency and increases production costs. Utility Model Content

[0013] As a further technical solution, the first detection device includes: The testing rack is mounted on the box. The detection head is mounted on the detection frame.

[0014] This utility model's technical solution employs an automated structural design. An automatic feeding mechanism ensures stable feeding of the middle cover spring, avoiding positional deviations caused by manual loading. A precision handling mechanism moves the middle cover spring and the middle cover sheet between workstations, replacing the force fluctuations inherent in manual handling. Furthermore, a spot welding mechanism automates the welding of components on the support assembly, ensuring consistent welding force and position. This entire automated process eliminates individual differences in manual operation, stably controlling the fit gap between the riveting components and the middle cover sheet to meet a precision requirement of ≤0.03mm.

[0015] Furthermore, this invention utilizes a multi-mechanism collaborative automated operation mode, where the feeding mechanism, handling mechanism, spot welding mechanism, and first inspection device form a continuous production chain. The feeding mechanism automatically supplies the middle cover spring pieces, eliminating the need for manual feeding piece by piece. The handling mechanism replaces manual workstation transfer, reducing waiting time for workstation switching. The spot welding mechanism automatically welds without manual hand operation, and the synchronous cooperation of each mechanism eliminates the need for manual intervention in process connection. Compared to manual assembly, this invention enables continuous and uninterrupted production, significantly shortens the assembly and welding cycle of a single product, greatly improves overall production efficiency, and meets the needs of large-scale mass production.

[0016] Furthermore, this utility model achieves multiple cost reduction effects through its automated structure. On the one hand, the automatic feeding, handling, and spot welding mechanisms replace traditional manual operations, reducing reliance on manual labor and directly lowering labor costs. On the other hand, the first inspection device can inspect the welded parts in real time, promptly identify and remove defective products, and avoid rework costs caused by defective products flowing into subsequent processes. It also reduces after-sales costs caused by missed inspections during manual checks. In addition, the stability of automated operations can reduce component wear caused by human error, further reducing material waste costs and comprehensively achieving effective control of production costs.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-6 As shown, the present invention proposes an automatic assembly and welding device, including a housing 100, with casters at the bottom of the housing 100 for supporting the housing 100 and allowing the position of the housing 100 to be changed as needed; it also includes: A feeding mechanism 200 is located at one end of the housing 100; and the output end of the feeding mechanism 200 is connected to the conveyor 300 on the housing 100; the middle cover spring is fed through the feeding mechanism 200; specifically, a material belt is provided on the feeding mechanism 200, and a middle cover spring is stamped on the material belt; during use, the material belt enters the conveyor 300 through the feeding mechanism 200 and is conveyed within the conveyor 300; it should be noted that the feeding mechanism 200 in this utility model has a cutting function; when the material belt enters the conveyor 300, the material belt is cut, and individual middle cover springs are formed after cutting; The discharge platform 400 is located at the other end of the box 100. The middle cover is temporarily stored through the discharge platform 400. The middle cover can be placed on the discharge platform 400 by the robotic arm in the previous stage, or it can be conveyed to the discharge platform 400 by the conveyor belt in the previous stage. The specific implementation shall be subject to the actual situation, and this utility model will not further limit it. The unloading mechanism 500 is mounted on the housing 100; the support assembly 600 is mounted on the housing 100; the conveying mechanism 700 is mounted on the housing 100, which moves the middle cover spring and the middle cover piece between workstations; the spot welding mechanism 800 is mounted on the housing 100 and adjacent to the support assembly 600, which welds the middle cover spring and the middle cover piece on the support assembly 600; in actual use, the conveying mechanism 700 picks up the middle cover from the discharge table 400 and moves it to the support assembly 600; and the unloading mechanism 500 moves the middle cover spring from the conveyor 300... After extraction, the middle cover is transferred to the support assembly 600 and assembled with the middle cover spring piece via the support assembly 600. After assembly, the assembled middle cover and middle cover spring piece are transferred to the next station on the support assembly 600 via the transport mechanism 700 and placed below the spot welding mechanism 800. The spot welding mechanism 800 performs the first side welding on the middle cover and middle cover spring piece. After the first side welding is completed, the mechanism rotates to weld the second side of the middle cover and middle cover spring piece. After all welding is completed, the transport mechanism 700 continues to send the welded middle cover and middle cover spring piece to the next station on the support assembly 600. The first detection device 901 is installed on the housing 100; the first detection device 901 detects the welded middle cover spring and middle cover piece; the first detection mechanism detects the welded middle cover and middle cover spring, specifically, the welding condition, assembly condition and bending condition of the middle cover spring and middle cover; determines whether the middle cover spring and middle cover meet the usage requirements; realizes the distinction between good and defective products, and avoids confusion between good and defective products; it should be noted that the spot welding mechanism 800 in this utility model is preferably a spot welding machine in the prior art; in this utility model, the first detection device 901 is a CCD camera.

[0024] It should be noted that a controller is also provided in this utility model. The controller is preferably a single-chip microcomputer or PLC control board in the prior art. The controller is connected to the feeding mechanism 200, the unloading mechanism 500, the support group 600, the conveying mechanism 700, the spot welding mechanism 800 and the first detection device 901 respectively, and controls each part.

[0025] This utility model's technical solution employs an automated structural design. An automatic feeding mechanism 200 ensures stable feeding of the middle cover spring, avoiding positional deviations caused by manual feeding. A precision handling mechanism 700 moves the middle cover spring and the middle cover sheet between workstations, replacing the force fluctuations inherent in manual handling. Furthermore, a spot welding mechanism 800 automates the welding of components on the support assembly 600, ensuring consistent welding force and position. This entire automated process eliminates individual differences in manual operation, stably controlling the fit gap between the riveting components and the middle cover sheet to meet a precision requirement of ≤0.03mm. This effectively prevents component loosening during long-term use, significantly improving product structural stability and service life.

[0026] Furthermore, this invention utilizes a multi-mechanism collaborative automated operation mode, where the feeding mechanism 200, handling mechanism 700, spot welding mechanism 800, and first detection device 901 form a continuous production chain. The feeding mechanism 200 automatically supplies the middle cover spring pieces, eliminating the need for manual loading of each piece individually. The handling mechanism 700 replaces manual workstation transfer, reducing waiting time for workstation switching. The spot welding mechanism 800 performs automatic welding without manual hand operation, and the synchronous cooperation of each mechanism eliminates the need for manual intervention in process connection. Compared to manual assembly, this invention enables continuous and uninterrupted production, significantly shortens the assembly and welding cycle of a single product, greatly improves overall production efficiency, and meets the needs of large-scale mass production.

[0027] Furthermore, this utility model achieves multiple cost reduction effects through its automated structure. On the one hand, the automatic feeding, handling, and spot welding mechanism 800 replaces traditional manual operation links, reducing reliance on manual labor and directly reducing labor costs. On the other hand, the first detection device 901 can detect the welded parts in real time, promptly identify and remove defective products, avoid rework costs caused by defective products flowing into subsequent processes, and reduce after-sales costs caused by missed inspections during manual checks. In addition, the stability of automated operation can reduce component wear caused by human error, further compressing material waste costs and comprehensively achieving effective control of production costs.

[0028] like Figure 2As shown, this utility model also includes a second detection device 902, which is installed on the housing 100 and adjacent to the conveyor 300. The second detection device 902 detects the condition of the spring clips on the upper cover of the conveyor 300. When the material conveying mechanism 200 disconnects due to reasons such as this, the first detection device 901 detects that there is no material conveying in the conveyor 300, generates an alarm signal, and sends the alarm signal to the control device. The control device then controls the feeding mechanism 200 to stop operating and generates an alarm signal to notify the staff to handle the situation accordingly. In this utility model, the second detection device 902 is a CCD camera.

[0029] like Figure 2 and Figure 3 As shown, this utility model also includes a third detection device 903, which is mounted on the housing 100. The third detection device 903 detects the middle cover spring and middle cover sheet welded by the spot welding mechanism 800. Specifically, after the middle cover spring and middle cover are welded by the spot welding mechanism 800, the welded middle cover spring and middle cover are transferred to the support group 600 by the transport mechanism 700. The third detection device 903 detects the welding condition. If the welding does not meet the usage requirements, the spot welding mechanism 800 needs to be adjusted to avoid problems in the welding not being detected in time, resulting in an increased defect rate. The third detection device 903 includes a detection frame 931 and a detection head 932. The detection frame 931 is mounted on the housing 100, and the detection head 932 is mounted on the detection frame 931. The detection head 932 can be adjusted in position on the detection frame 931 to adapt to different detection conditions. In this utility model, the preferred detection head 932 is a CCD camera.

[0030] like Figure 3 As shown, the feeding mechanism 200 includes a feeding rack 201, a first driving device 202, a feeding channel 204, and a cutting device 205. The feeding rack 201 is located at one end of the housing 100. The first driving device 202 is located on the feeding rack 201, and a material wheel 203 is located on the first driving device 202. The feeding channel 204 is located on the feeding rack 201 and is connected to the conveyor channel 300. The cutting device 205 is located on the feeding channel 204. During use, the first driving device 202 drives the material wheel 203 to rotate, and the material wheel 203 conveys the material belt to the feeding channel 204. After being conveyed in the feeding channel 204, the material belt enters the conveyor channel 300. As the material belt is conveyed in the conveyor, when it reaches the area below the cutting device 205, the cutting device 205 cuts the material belt and forms a middle cover spring after cutting. It should be noted that the cutting device 205 includes a cutting frame mounted on the conveyor 300, and a cylinder and a cutter mounted on the cutting frame. The piston rod of the cylinder is connected to the cutter. When the material strip is placed below the cutting mechanism, the cylinder drives the cutter to cut the material strip. In addition, two cutting devices 205 are mounted on the conveyor 300, which can cut the material strip simultaneously. Alternatively, the material strip can be cut on both sides separately. The specific method depends on the actual situation, and this utility model will not describe it further. However, it should be noted that the conveying position of the material strip can be calculated by the number of rotations of the first driving device 202, and the start and stop of the first driving device 202 can be controlled by the controller to ensure that the first driving device 202 is in a stopped state when cutting the material strip. Of course, a position sensor can also be mounted at an adjacent position of the cutting frame to obtain the position of the material strip, and then send the obtained position information to the control device, which controls the first driving device 202 and the cylinder to operate respectively.

[0031] like Figure 3 As shown, the unloading mechanism 500 includes an unloading frame 501, a limiting plate 502, a second driving device 503, and an unloading arm 505. The unloading frame 501 is mounted on the housing 100. The limiting plate 502 is mounted on the unloading frame 501. The second driving device 503 is mounted on the unloading frame 501, and its output end passes through the limiting plate 502 and is connected to the swing arm 504. The unloading arm 505 is slidably mounted on the unloading frame 501, with one end connected to the swing arm 504. A unloading head 506 is provided at the other end of the unloading arm 505. During use, the second driving device 503 drives the swing arm 504 to rotate, and the swing arm 504 drives the unloading process. Arm 505 slides on unloading rack 501, thereby changing the position of unloading head 506. When unloading head 506 is placed above conveyor 300, after the unloading head 506 extracts the middle cover spring, the second drive device 503 reverses its action and causes the extraction head 743 to place the middle cover spring on the support group 600. At this time, the support group 600 already has the middle cover. When unloading head 506 separates from the middle cover spring, the middle cover spring is placed on the middle cover. In this utility model, the second drive device 503 is preferably a motor; the unloading head 506 is preferably a plurality of first suction cups, wherein the number of first suction cups is not less than two, and is connected to the air source through a cylinder. like Figure 1 , Figure 5 and Figure 6As shown, the support assembly 600 includes an assembly support 601, a spot welding support 602, and an inspection support, which are sequentially arranged on the housing 100. Specifically, the assembly support 601 is located below the unloading mechanism 500, the spot welding support 602 is located below the spot welding mechanism 800, and the inspection support is located below the first inspection device 901. When the middle cover spring and the middle cover are moved by the conveying mechanism 700, they will be placed on the assembly support 601, the spot welding support 602, and the inspection support, respectively. The assembly support unit 601 includes a mounting platform 611 mounted on the housing 100; a first assembly device 612 and a second assembly device 613 are arranged opposite each other on the mounting platform 611; a connecting plate 614 is provided between the first assembly device 612 and the second assembly device 613; a third drive device 615 is mounted on the mounting platform 611 and connected to the connecting plate 614; the first assembly device 612 and the second assembly device 613 move within the slide rails on the mounting platform 611 under the drive of the third drive device 615; specifically; the middle cover is moved from the discharge platform 400 to the first assembly device 612 by the conveying mechanism 700, the middle cover is limited by the first assembly device 612, and the middle cover spring piece on the conveyor 300 is moved to the first assembly device 612 by the unloading mechanism 500, the middle cover spring piece and the middle cover are assembled by the first assembly device 612, and after assembly, the middle cover spring piece and the middle cover are assembled by the conveying machine. Driven by mechanism 700, the middle cover spring and the middle cover are transferred to the second assembly device 613. After the middle cover spring and the middle cover on the first assembly device 612 are transferred, the conveying mechanism 700 transfers the next middle cover on the discharge platform 400 to the first assembly device 612, and the middle cover spring is transferred to the next middle cover through the unloading mechanism 500. When the middle cover and the middle cover spring processed on the first assembly device 612 are placed in the second assembly device 613, the middle cover spring and the middle cover are positioned by the second assembly device 613. During the positioning process, the middle cover is squeezed and bent to complete the assembly of the first middle cover and the middle cover spring. At this time, the rotary cylinder behind the first assembly device 612 and the second assembly device 613 starts to rotate, completing the middle cover reversal and flipping the other side without the spring to the top. The process structure for installing the second middle cover spring has been explained once and will not be repeated here.

[0032] It should be noted that the assembly support 601, the spot welding support 602 and the testing support have the same structure, except that the length of the connecting plate 614 on the spot welding support 602 is different from that on the assembly support 601 and the testing support; the other structures are the same, and for the sake of saving space, this utility model will not be described in detail.

[0033] like Figure 4As shown, the conveying mechanism 700 includes a conveying frame 701, a conveying plate 702, a fourth drive device 703, and several conveying devices 704. The conveying frame 701 is mounted on the housing 100. The conveying plate 702 is mounted on a slide rail on the conveying frame 701. The fourth drive device 703 is mounted on the conveying frame 701 and connected to the conveying plate 702. Several conveying devices 704 are mounted on the conveying plate 702. Driven by the fourth drive device 703, the conveying plate 702 slides on the slide rail of the conveying frame, thereby driving the several conveying devices 704 to perform actions. The middle cover and the middle cover spring piece are then delivered to the assembly support part 601, the spot welding support part 602, and the detection support part, respectively, through the several conveying devices 704. Preferably, the fourth drive device 703 is a motor. The conveying device 704 includes a connecting plate 741, an extraction frame 742, and a fifth driving device 744.
