Description

Technical Field

[0001] This invention relates to the field of PCBA manufacturing technology, and more specifically, to an unmanned automated insertion system. Background Technology

[0002] In related technologies, in order to reduce manual intervention, components on PCBA are usually inserted using insertion machines. However, insertion machines can only insert some regularly shaped components, while some irregularly shaped components still need to be inserted manually, resulting in low production efficiency. For non-standard insertion machines, inserting components of different shapes requires matching and replacing different specifications of feed feeders or vibratory feeders, which is costly, has low replacement efficiency, cannot achieve universality and compatibility, and requires manual intervention.

[0003] Therefore, existing technologies need to be improved and developed. Summary of the Invention

[0004] The purpose of this invention is to provide an unmanned automatic insertion system that can switch between different specifications of materials simply by calling different specifications of pallet materials through a program, thereby realizing automated production of PCBA without manual operation, achieving unmanned production and effectively improving production efficiency.

Detailed Implementation

[0040] The following drawings disclose several embodiments of the present invention. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0042] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0043] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0044] PCBAs typically have multiple components 400, and the components 400 differ between different PCBAs. Currently, to reduce manual intervention, insertion machines are commonly used to insert the components 400 provided by feeding equipment onto the printed circuit board, achieving automated PCBA production. However, existing feeding equipment can only feed one type of component 400. Therefore, automated insertion requires multiple different feeding devices to provide different components 400 to the insertion machine. This means that the same production line can only produce one type of PCBA. If the insertion machine is to be used to produce different PCBAs, it needs to be stopped and replaced with a feeding device capable of feeding components 400 for a different type of PCBA, which is very cumbersome. In addition, insertion machines can only insert some regularly shaped components 400, while some irregularly shaped components 400 still require manual insertion, resulting in low production efficiency. Based on this, the present invention provides an unmanned automated insertion system.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention provides an unmanned automatic insertion system, including an insertion machine 100, multiple feeding devices 200, and at least one AGV trolley 300. The insertion machine 100 has a carrier track 101 and a gripping device 102, with the carrier track 101 located on the moving path of the gripping device 102. Each feeding device 200 has a feeding area within the gripping range of the gripping device 102. Each feeding device 200 includes a frame 1, a conveying device 2, a lifting device 3, a buffer device 4, a transfer device 5, and a feeding device 6. The conveying device 2, lifting device 3, buffer device 4, transfer device 5, and feeding device 6 are all mounted on the frame 1. The conveying device 2 is used to convey multiple trays stacked sequentially from bottom to top. The lifting device 3 is located on the conveying path of the conveying device 2 and is used to drive one or more trays to move up and down. The buffer device 4 and the transfer device 5 are both located on the lifting path of the lifting device 3, and the buffer device 4 is located above the transfer device 5. The buffer device 4 is used to buffer one or more trays. The transfer device 5 is used to transfer a tray to the feeding device 6. The feeding device 6 is located on the lifting path of the lifting device 3 and corresponds to the transfer device 5. The feeding device 6 is used to convey a tray to the feeding area and to convey the tray from the feeding area back to the transfer device 5. At least one AGV trolley 300 is used to transport multiple trays stacked sequentially from bottom to top on a shelf to a conveyor 2 and to transport multiple empty trays stacked sequentially from bottom to top to a designated location.

[0046] In practical applications, the AGV trolley 300 transports multiple trays containing components 400 stacked sequentially from bottom to top on the shelf to the feeding equipment 200. The feeding equipment 200 feeds multiple trays containing components 400, and the gripping device 102 grips multiple components 400 from multiple trays one by one and inserts them into the PCB board 500 conveyed by the carrier track 101, thereby realizing the automated production of PCBA and improving production efficiency.

[0047] Specifically, the carrier track 101 is existing technology and will not be described in detail here.

[0048] Specifically, the gripping device 102 includes an X-axis linear module, a Y-axis linear module, a Z-axis linear module, and a gripping component. The Y-axis linear module is connected to the X-axis linear module, the Z-axis linear module is connected to the Y-axis linear module, and the gripping component is connected to the Z-axis linear module. The X-axis, Y-axis, and Z-axis linear modules cooperate to drive the gripping component to move in the X, Y, and Z directions, thereby achieving precise gripping of multiple components 400 mounted on the tray. In practical applications, the gripping component can be a clamp.

[0049] In practical applications, each tray has a lifting support, a transfer support, and a buffer support, which are arranged sequentially from bottom to top. Specifically, the lifting support is the bottom plane of the tray, the transfer support is a stepped platform on the side wall of the tray, and the buffer support is an insertion hole on the side wall of the tray.

[0050] For ease of explanation, we will take the feeding process of the feeding device 200 feeding N material trays as an example (N is a natural number greater than 1) to explain the feeding process of the feeding device 200.

[0051] First, the AGV trolley 300 removes N trays containing components 400 stacked sequentially from bottom to top from the shelf and places them on the conveyor 2. The conveyor 2 transports the N trays containing components 400 stacked sequentially from bottom to top to the lifting device 3. The lifting device 3 drives the N trays containing components 400 to rise to correspond with the buffer device 4. The buffer device 4 buffers the remaining N-1 trays of the N trays containing components 400, excluding the bottom tray.

[0052] Secondly, the lifting device 3 drives one of the bottom trays to move downwards to correspond with the transfer device 5. The transfer device 5 transfers the tray to the feeding device 6, which then conveys it to the feeding area for the insertion machine 100 to grab. After the insertion machine 100 has taken all the components 400 on the tray, the feeding device 6 conveys the tray back to the transfer device 5.

[0053] Next, the lifting device 3 drives one tray to move upward to the bottom of the N-1 trays containing components 400 that are buffered by the buffer device 4. The buffer device 4 releases the buffer on the N-1 trays containing components 400. The lifting device 3 drives one empty tray and the N-1 trays containing components 400 to move downward by the height of one tray. The buffer device 4 buffers the N-2 trays (excluding the bottom tray) of the N-1 trays containing components 400.

[0054] Then, the lifting device 3 drives an empty tray and a tray containing components 400 on it to move downwards until the tray containing components 400 aligns with the transfer device 5. The transfer device 5 then transfers the tray containing components 400 to the feeding device 6, which conveys it to the feeding area for the insertion machine 100 to pick up. After the insertion machine 100 has removed all the components 400 from the tray, the feeding device 6 returns the tray to the transfer device 5.

[0055] Next, the lifting device 3 drives two empty trays upward to the bottom of the N-2 trays containing components 400 that are buffered by the buffer device 4. The buffer device 4 releases the buffer on the N-2 trays containing components 400. The lifting device 3 drives the two empty trays and the N-2 trays containing components 400 downward by the height of one tray. The buffer device 4 buffers N-3 trays (excluding the bottom tray) of the N-2 trays containing components 400. The lifting device 3 drives the two empty trays and the tray containing components 400 above them downward until the tray containing components 400 corresponds to the transfer device 5. The transfer device 5 transfers the tray containing components 400 to the feeding device 6. The feeding device 6 then... The components are conveyed to the feeding area for the insertion machine 100 to grab. After the insertion machine 100 has taken all the components 400 on the tray, the feeding device 6 conveys the tray back to the transfer device 5. The above actions are repeated until the lifting device 3 drives N-1 empty trays and one tray containing components 400 on them to move downwards until the tray containing components 400 corresponds to the transfer device 5. At this time, there are no trays buffered at the buffer device 4. The transfer device 5 transfers the tray containing components 400 to the feeding device 6. The feeding device 6 conveys it to the feeding area for the insertion machine 100 to grab. After the insertion machine 100 has taken all the components 400 on the tray, the feeding device 6 conveys the tray back to the transfer device 5.

[0056] Finally, the lifting device 3 drives N empty trays to move downwards to correspond with the conveying device 2. The conveying device 2 transports the N empty trays to the unloading end of the conveying device 2. The AGV trolley 300 transports the N empty trays to the designated position. Then, the N trays containing components 400, which are stacked sequentially from bottom to top, are taken from the shelf and placed on the conveying device 2. The above actions are repeated to realize the continuous production of PCBA.

[0057] Specifically, the aforementioned feeding area refers to the front end area of ​​the feeding device 6.

[0058] Understandably, when it is necessary to produce another type of PCBA, it is only necessary to change the tray containing the components 400 required for producing the other type of PCBA and change the corresponding execution software through the control system. In this way, there is no need to stop the machine.

[0059] It should be noted that during PCBA production, there are several types of components 400 on the PCBA, and correspondingly, there are several feeding devices 200 corresponding to the insertion machine 100. For example, if there are four types of components 400 on the PCBA, there are four feeding devices 200 corresponding to the insertion machine 100, each providing one of the four types of components 400. Alternatively, multiple types of components 400 can be loaded onto a single tray; for example, if there are four types of components 400 on the PCBA, all four types of components 400 can be contained in one tray.

[0060] like Figure 5 As shown, the conveying device 2 includes a conveying motor 21, multiple conveying rollers 22, and a conveyor belt 23. The conveying motor 21 is mounted on the frame 1. The multiple conveying rollers 22 are arranged in parallel on the upper frame 1, and one of the multiple conveying rollers 22 is connected to the output end of the conveying motor 21. The conveyor belt 23 is wound around the multiple conveying rollers 22.

[0061] In practical applications, the conveyor motor 21 drives the conveyor roller 22 connected to its output end to rotate. This conveyor roller 22 drives the other conveyor rollers 22 to rotate via the conveyor belt 23, thereby realizing the conveying of multiple trays stacked sequentially from bottom to top on the conveyor belt 615. It can be understood that by controlling the conveyor motor 21 to rotate forward, the conveying device 2 can convey multiple trays containing components 400 stacked sequentially from bottom to top to the lifting device 3. By controlling the conveyor motor 21 to rotate in reverse, the conveying device 2 can transport multiple empty trays stacked sequentially from bottom to top to the loading end of the conveying device 2 via the lifting device 3.

[0062] like Figure 6 , Figure 7 as well as Figure 8 As shown, the lifting device 3 includes two opposing lifting mechanisms 31. Each lifting mechanism 31 includes a lifting drive shaft 311, two lifting drive wheels 312, two lifting driven wheels 313, two lifting belts 314, two lifting guide rails 315, two lifting sliders 316, and a lifting support plate 317. The lifting drive shaft 311 is rotatably mounted on the frame 1. The two lifting drive wheels 312 are opposite to each other and are respectively connected to both ends of the lifting drive shaft 311. The two lifting driven wheels 313 are rotatably mounted on the frame 1 and correspond to the two lifting drive wheels 312 respectively. The two lifting belts 314 are respectively wound around the two lifting drive wheels 312 and the two corresponding lifting driven wheels 313. The two lifting guide rails 315 are vertically laid on the frame 1. The two lifting sliders 316 are slidably mounted on the two lifting guide rails 315 and are respectively connected to the two lifting belts 314. The two ends of the lifting support plate 317 are respectively connected to the two lifting sliders 316.

[0063] In practical applications, the two lifting drive shafts 311 are each connected to one lifting drive motor, or both lifting drive shafts 311 are connected to one lifting drive motor via a transmission structure. After the conveying device 2 transports multiple pallets to the corresponding lifting device 3, the lifting drive motor drives the lifting drive shafts 311 to rotate. The lifting drive shafts 311 drive the lifting drive wheel 312 to rotate. The lifting drive wheel 312 drives the lifting driven wheel 313 to rotate via the lifting belt 314. The lifting belt 314 drives the lifting pallet 317 connected to the slider to move up and down along the lifting guide rail 315, thereby causing the bottom plane of the lifting pallet 317 supporting the material tray to move up and down. Specifically, the two lifting drive shafts 311 are each connected to one lifting drive motor via a transmission structure. This not only reduces production costs but also ensures that the two lifting mechanisms 31 are synchronized.

[0064] like Figure 9 as well as Figure 10 As shown, the aforementioned buffer device 4 includes two buffer mechanisms 41 arranged opposite to each other. Each buffer mechanism 41 includes a buffer mounting plate 411, two buffer mounting blocks 412, a buffer movable plate 413, a buffer reset spring 414, a buffer lifting plate 415, and a buffer drive cylinder 416. The buffer mounting plate 411 is mounted on the frame 1. The two buffer mounting blocks 412 are arranged opposite to each other on the buffer mounting plate 411. The buffer movable plate 413 is movably mounted on the two buffer mounting blocks 412, and has multiple inserts 4131. One end of the buffer reset spring 414 abuts against the buffer movable plate 413, and the other end of the buffer reset spring 414 abuts against the frame 1. The buffer lifting plate 415 is slidably mounted on the buffer mounting plate 411 and movably abuts against the buffer movable plate 413. The buffer drive cylinder 416 is mounted on the buffer mounting plate 411, and its output end is connected to the buffer lifting plate 415.

[0065] In practical applications, the lifting device 3 raises multiple trays containing components 400 to correspond with the buffer device 4. Then, the buffer drive cylinder 416 drives the buffer lifting plate 415 to move towards the buffer movable plate 413. The first inclined surface on the buffer lifting plate 415 cooperates with the second inclined surface on the buffer movable plate 413, causing the buffer movable plate 413 to move towards the buffer mounting plate 411. This allows the insert block 4131 to pass through the buffer mounting plate 411 and insert into the insertion hole on the side wall of the tray, thus buffering the tray and the trays above it. When the insert block 4131 is inserted into the insertion hole on the side wall of the tray, the buffer reset spring 414 is compressed. When the buffer device 4 needs to release the buffer from the tray, the drive cylinder drives the buffer lifting plate 415 to move upward. The buffer reset spring 414 returns to its uncompressed state and pushes the buffer movable plate 413 away from the buffer mounting plate 411, thereby causing the insert block 4131 to disengage from the insertion hole on the side wall of the tray and releasing the buffer from the tray.

[0066] Preferably, the aforementioned buffer mechanism 41 further includes a buffer linear guide rail 417, which is mounted on the buffer mounting plate 411 and connected to the buffer lifting plate 415. This ensures that the buffer lifting plate 415 performs high-precision linear motion under the drive of the buffer drive cylinder 416.

[0067] Preferably, the aforementioned buffer mechanism 41 further includes two sets of buffer rollers, which are respectively mounted on two buffer mounting blocks 412. Each set of buffer rollers includes two buffer rotating rollers 418, which respectively abut against the upper and lower surfaces of the buffer movable plate 413. This technical solution not only limits the vertical movement of the buffer movable plate 413 but also enables precise horizontal movement of the buffer movable plate 413.

[0068] like Figure 11 , Figure 12 as well as Figure 13 As shown, the aforementioned transfer device 5 includes two opposing transfer support mechanisms 51 and a transfer pushing mechanism 52. Each transfer support mechanism 51 includes two transfer support mounting blocks 511, a transfer support movable plate 512, a transfer support return spring 513, a transfer support lifting plate 514, a transfer support drive cylinder 515, a transfer pushing cylinder 521, and a transfer pushing rod 522. The two transfer support mounting blocks 511 are opposingly mounted on the buffer mounting plate 411. The transfer support movable plate 512 is movably mounted on the two transfer support mounting blocks 511, and a transfer support plate 5121 is provided on the transfer support movable plate 5121. One end of the transfer support return spring 513 abuts against the transfer support movable plate 512, and the other end of the transfer support return spring 513 abuts against the frame 1. The transfer support lifting plate 514 is slidably mounted on the buffer mounting plate 411 and movably abuts against the transfer support movable plate 512. The transfer support drive cylinder 515 is mounted on the frame 1, and its output end is connected to the transfer support lifting plate 514. The transfer pushing mechanism 52 includes a transfer pushing cylinder 521 and a transfer pushing rod 522. The transfer pushing cylinder 521 is rotatably mounted on the frame 1, one end of the transfer pushing rod 522 is rotatably mounted on the frame 1, and the middle part of the transfer pushing rod 522 is connected to the output end of the transfer pushing cylinder 521.

[0069] In practical application, after the lifting device 3 drives the tray containing the components 400 to correspond with the transfer device 5, the transfer support drive cylinder 515 drives the transfer support lifting plate 514 to move in the transfer direction. The third inclined surface on the transfer support lifting plate 514 cooperates with the fourth inclined surface on the transfer cup, so that the transfer support moving plate 512 moves in the direction of the buffer mounting plate 411, thereby allowing the transfer support plate 5121 to pass through the stepped platform on the side wall of the tray supported by the buffer mounting plate 411. Then, the transfer push cylinder 521 drives the transfer push rod 522 to rotate around the movement of the transfer push rod 522 as the rotation center. The transfer push rod 522 pushes the tray supported by the transfer support plate 5121 to the work position of the feeding device 6.

[0070] Preferably, the aforementioned transfer support mechanism 51 further includes a transfer support linear guide rail 516, which is mounted on the buffer mounting plate 411 and connected to the transfer support lifting plate 514. This ensures that the transfer support lifting plate 514 performs high-precision linear motion under the drive of the transfer support drive cylinder 515.

[0071] Preferably, the aforementioned transfer support mechanism 51 further includes two sets of transfer support rollers, which are respectively mounted on two transfer support mounting blocks 511. Each set of transfer support rollers includes two transfer support rotating rollers 517, which respectively abut against the upper and lower surfaces of the transfer support movable plate 512. This technical solution not only limits the vertical movement of the transfer support movable plate 512 but also enables precise horizontal movement of the transfer support movable plate 512.

[0072] like Figure 14 as well as Figure 15 As shown, the feeding device 6 includes a conveying mechanism 61. The conveying mechanism 61 receives the tray transferred by the transfer device 5, conveys the tray to the feeding area, and returns the tray to the transfer device 5 after all the components 400 on it have been removed. Specifically, the conveying mechanism 61 includes a conveying drive motor 611, a conveying drive rod 612, two conveying drive wheels 613, two conveying driven wheels 614, and two conveyor belts 615. The conveying drive motor 611 is mounted on the frame 1. The conveying drive rod 612 is rotatably mounted on the frame 1 and connected to the output shaft of the conveying drive motor 611. The two conveying drive wheels 613 are arranged opposite each other and connected to both ends of the conveying drive rod 612. The two conveying driven wheels 614 are arranged opposite each other on the frame 1 and correspond to the two conveying drive wheels 613. The two conveyor belts 615 are respectively wound around the two conveying drive wheels 613 and their corresponding two conveying driven wheels 614.

[0073] In practical applications, the conveyor drive motor 611 drives the conveyor drive rod 612 to rotate, which in turn drives two conveyor drive wheels 613 to rotate. These two drive wheels 613, via two conveyor belts 615, drive two conveyor driven wheels 614 to rotate, and the two conveyor belts 615 move the material tray. It can be understood that by controlling the forward or reverse rotation of the conveyor drive motor 611, the conveyor mechanism 61 can convey the material tray to the feeding area or return it to the transfer device 5.

[0074] Specifically, a support plate 616 is provided between the corresponding driving conveyor wheel 613 and driven conveyor wheel 614. The support plate 616 is mounted on the frame 1 and located inside the conveyor belt 615. When the two conveyor belts 615 convey the material tray, the two support plates 616 not only support the conveyor belt 615, preventing excessive sagging or deformation due to gravity or load during operation, thus maintaining the flatness and straightness of the conveyor belt 615, avoiding collision and friction with the frame 1, and extending the equipment's lifespan, but also transmit and distribute the load, evenly transferring the weight of the conveyor belt 615 to the frame 1, reducing local stress concentration, and improving the overall structural stability.

[0075] In some preferred embodiments, the feeding device 6 further includes a tray fixing mechanism 62. After the conveying mechanism 61 conveys the tray to the feeding area, the tray fixing mechanism 62 fixes the tray. Specifically, the tray fixing mechanism 62 includes a front fixing baffle 621, a rear fixing plate 622, a rear fixing drive cylinder 623, a left fixing baffle 624, a right fixing plate 625, and a right fixing cylinder 626. The front fixing baffle 621 is mounted on the frame 1 and located at the front of the feeding area. The rear fixing plate 622 is rotatably mounted on the frame 1 and located at the rear of the feeding area. The rear fixing drive cylinder 623 is mounted on the frame 1, and its output end is connected to the rear fixing plate 622. The rear fixing drive cylinder 623 can drive the rear fixing plate 622 to rotate, so that the rear fixing plate 622 abuts against the rear end of the tray. The left fixing baffle 624 is mounted on the frame 1 and located on the left side of the feeding area. The right fixed plate 625 is mounted on the frame 1 and is opposite to the left fixed baffle 624. The right fixed cylinder 626 is mounted on the frame 1, and its output end is connected to the right fixed plate 625.

[0076] In practical applications, after the conveying mechanism 61 conveys the material tray to the feeding area, the rear fixed drive cylinder 623 drives the rear fixed plate 622 to rotate, causing the rear fixed plate 622 to push the material tray forward, so that the front end of the material tray abuts against the front fixed baffle 621 and the rear end of the material tray abuts against the rear fixed plate 622, thereby fixing the material tray in the front-back direction. At the same time, the right fixed cylinder 626 drives the right fixed plate 625 to move to the left, so that the right fixed plate 625 pushes the material tray to the left, so that the left end of the material tray abuts against the left fixed baffle 624 and the right end of the material tray abuts against the right fixed plate 625, thereby fixing the material tray in the left-right direction.

[0077] In practical applications, the range of motion of the gripping mechanism of the component gripping machine 100 400 is fixed. To avoid incompatibility between the feeding device 200 and the component gripping machine 100, in some preferred embodiments, the feeding device 6 further includes a switching mechanism 63. The switching mechanism 63 is located between the transfer device 5 and the feeding area. After half of the components 400 on the tray in the feeding area are picked up, the conveying mechanism 61 conveys the tray to the switching mechanism 63, and the switching mechanism 63 drives the tray to rotate horizontally by 180°.

[0078] It should be noted that the material tray has two symmetrically arranged loading areas. When half of the components 400 on the material tray in the feeding area are taken out, it means that all the components 400 in one loading area are taken out.

[0079] like Figure 15 , Figure 16 as well as Figure 17As shown, the switching mechanism 63 includes a switching component 631 and a limiting component 632. The switching component 631 drives the material tray to rotate horizontally by 180°. The limiting component 632 limits the material tray when the conveying mechanism 61 conveys the material tray in the feeding area to the switching component 631. Specifically, the switching component 631 includes a lifting mounting plate 6311, a lifting moving plate 6312, multiple lifting guide rods 6313, a lifting drive cylinder 6314, a rotation drive motor 6315, a rotation drive gear 6316, a rotation driven gear 6317, and a rotating plate 6318. The lifting mounting plate 6311 is mounted on the frame 1. The lifting moving plate 6312 is located above the lifting mounting plate 6311, one end of the multiple lifting guide rods 6313 is connected to the lifting moving plate 6312, and the other end of the multiple lifting guide rods 6313 passes through the lifting mounting plate 6311. A lifting drive cylinder 6314 is mounted on a lifting mounting plate 6311, and its output end is connected to a lifting moving plate 6312. A rotation drive motor 6315 is mounted on the lifting moving plate 6312. A rotation drive gear 6316 is connected to the output shaft of the rotation drive motor 6315. A rotation driven gear 6317 is rotatably mounted on the lifting moving plate 6312 and meshes with the rotation drive gear 6316. A rotating plate 6318 is connected to the rotation driven gear 6317. The limiting assembly 632 includes a limiting drive cylinder 6321 and a limiting post 6322. The limiting drive cylinder 6321 is mounted on the frame 1 and located behind the switching assembly 631. The extension and retraction direction of the output end of the limiting drive cylinder 6321 is the same as the lifting direction of the lifting assembly. The limiting post 6322 is connected to the output end of the limiting drive cylinder 6321.

[0080] In specific applications, when the conveying mechanism 61 conveys the material tray from the feeding area to the switching mechanism 63, the limit drive cylinder 6321 drives the limit post 6322 to extend, so that the limit post 6322 can limit the material tray, making the material tray precisely correspond to the switching component 631. Then, the lifting drive cylinder 6314 drives the lifting moving plate 6312 to move upward along multiple lifting guide rods 6313. The lifting moving plate 6312 drives the rotating drive gear 6316, the rotating driven gear 6317, and the rotating plate 6318 to move upward. The rotating plate 6318 drives the material tray to move upward. After the lifting moving plate 6312 moves upward into position, the rotating drive motor 6315 drives the rotating drive gear 6316 to rotate. The driven gear 6317 rotates, which in turn drives the rotating plate 6318 to rotate. The rotating plate 6318 rotates the material tray 180°, so that the half of the material tray containing the component 400 that has been picked up by the connector becomes the rear end, and the half of the component 400 that has not yet been picked up by the connector becomes the front end. Then, the lifting drive cylinder 6314 drives the lifting moving plate 6312 to move downward along multiple lifting guide rods 6313. The lifting moving plate 6312 drives the rotating drive gear 6316, the rotating driven gear 6317, and the rotating plate 6318 to move downward. The rotating plate 6318 drives the material tray to move downward. After the lifting moving plate 6312 moves downward into place, the conveying mechanism 61 conveys the material tray to the feeding area again.

[0081] like Figure 18 and Figure 19 As shown, the feeding device 6 also includes a discharging mechanism 64. The discharging mechanism 64 is used to push the empty material tray when the conveying mechanism 61 transfers the empty tray back to the transfer device 5. Specifically, the discharging mechanism 64 includes a discharging mounting plate 641, a discharging drive cylinder 642, a discharging connecting plate 643, a discharging push block 644, and a discharging return spring 645. The discharging mounting plate 641 is mounted on the frame 1 and has an opening. The discharging drive cylinder 642 is mounted on the discharging mounting plate 641. The discharging connecting plate 643 is connected to the output end of the discharging drive cylinder 642. One end of the discharging push block 644 is rotatably mounted on the discharging mounting plate 641. One end of the discharging return spring 645 abuts against the discharging connecting plate 643, and the other end of the discharging return spring 645 abuts against the discharging push block 644. Preferably, the discharging drive cylinder 642 is a rodless cylinder.

[0082] In practical applications, under the default state, the feeding pusher 644 is entirely located below the feeding mounting plate 641. At this time, the feeding reset spring 645 is compressed, causing the other end of the feeding pusher 644 to abut against the lower surface of the feeding mounting plate 641. When the conveying mechanism 61 transfers the empty material tray from the feeding area back to the transfer device 5, the conveying mechanism 61 first transfers the empty material tray to the feeding mechanism 64. Then, the feeding drive cylinder 642 drives the feeding connecting plate 643 to move towards the transfer device 5. The feeding connecting plate 643 drives the feeding pusher 644 to move towards the transfer device 5. When the other end of the feeding pusher 644 corresponds to the opening, the other end of the feeding pusher 644 is at the bottom. Under the action of the material return spring 645, the material passes through the opening from bottom to top. As the material feeding connecting plate 643 continues to move, the other end of the material feeding push block 644 pushes the material tray to the station of the transfer device 5. Then, the material feeding drive cylinder 642 drives the material feeding connecting plate 643 to move towards the feeding area. The material feeding connecting plate 643 drives the material feeding push block 644 to move towards the feeding area. As the material feeding connecting plate 643 moves, the other end of the material feeding push block 644 passes through the opening from top to bottom and gradually abuts against the material feeding mounting plate 641. Under the action of the material feeding mounting plate 641, the material feeding push block 644 and the material feeding return spring 645 both return to their default state, waiting for the next material feeding to perform the corresponding action.

[0083] In order to ensure that the material feeding pusher 644 can smoothly switch back to the default state after pushing the material tray to the station of the transfer device 5, the material feeding pusher 644 is provided with a fifth inclined surface, and the material feeding mounting plate 641 is provided with a sixth inclined surface that matches the fifth inclined surface. The fifth and sixth inclined surfaces cooperate with each other to ensure that the material feeding pusher 644 can smoothly switch back to the default state.

[0084] Preferably, the above-mentioned unloading mechanism 64 further includes an unloading linear guide rail 646, which is disposed on the unloading mounting plate 641 and connected to the unloading connecting plate 643. This ensures that the unloading connecting plate 643 performs high-precision linear motion under the drive of the unloading drive cylinder 642, thereby ensuring that the unloading push block 644 performs high-precision linear motion.

[0085] In practical applications, the frame 1 is equipped with multiple sensors, which correspond to the conveying device 2, lifting device 3, buffer device 4, transfer device 5, and feeding device 6. These sensors detect whether each device has completed its designated movement. If so, the sensor sends a signal to the control system of the unmanned automatic insertion system. The control system then stops the affected device and controls other devices to perform corresponding actions, ensuring the accuracy of the feeding equipment 200. For example, if a sensor detects that the conveying device 2 has delivered multiple trays to the designated position, it sends a signal to the control system, which then stops the conveying device 2 and activates the lifting device 3. Specifically, the sensors can be photoelectric switches.

[0086] In practical applications, the aforementioned insertion machine 100, multiple feeding devices 200, and at least one AGV trolley 300 are all electrically connected to the control system of the unmanned automatic insertion system. The control system of the unmanned automatic insertion system controls the operation of the insertion machine 100, multiple feeding devices 200, and at least one AGV trolley 300 to achieve the automated control effect of the unmanned automatic insertion system. Of course, the control system of the unmanned automatic insertion system can be any of an industrial computer, PLC, or microcontroller, which will not be elaborated further here.

[0087] In summary, in one or more embodiments of the present invention, the unmanned automatic insertion system of the present invention achieves automated production of PCBA through the cooperation of insertion machine, feeding equipment and AGV trolley, effectively improving production efficiency.

[0088] The above description is merely an embodiment of the present invention and is not intended to limit the invention.
