Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-2 As shown, this utility model provides a PCB board receiving device, including a frame 1. The frame 1 is provided with a conveying assembly 2, a receiving assembly 3, and a robotic arm assembly 4 from bottom to top. The conveying assembly 2 has several tooling positions 23, and the receiving assembly 3 is correspondingly arranged on the tooling positions 23. The tooling positions 23 include a first workstation 231 and a second workstation 232 arranged side-by-side along the Y-axis. The first workstation 231 is a receiving position, and the second workstation 232 is a waiting position. A feeding assembly 7 is also provided on the frame 1 at the first workstation 231. The feeding assembly 7 has a feeding position 71, which corresponds to the first workstation 231 for material transfer. Below the first workstation 231 and the second workstation 232, there are respectively a first ejector assembly 5 and a second ejector assembly 6 that engage with the receiving assembly 3 vertically. The first ejector assembly 5 is used to drive... The receiving component 3 located above it is used for loading. Since the material volume is relatively small, in order to improve the material receiving volume and production efficiency, there is a certain height between the first station 231 and the feeding station 71. Therefore, in order to place the material intact and accurately on the first station 231 at the feeding station 71, the receiving component 3 is driven by the first ejection component 5 to rise and move closer to the feeding station 71. The frame 1 is also equipped with an optical fiber sensor 72. After each material is received, the material will be stacked. Therefore, the height of the first ejection component 5 rising each time is different. When the material on the receiving component 3 is sensed by the optical fiber sensor 72, it is the optimal height for receiving. At this time, the first ejection component 5 will stop driving, and the material on the feeding station 71 will fall and be placed on the receiving component 3. The receiving component 3 will then descend and reset under the drive of the first ejection component 5.

[0032] The robotic arm assembly 4 is located above the receiving assembly 3. When the material carried by the receiving assembly 3 at the first station 231 reaches its maximum capacity, the receiving assembly 3 moves along the X-axis direction under the drive of the conveying assembly 2 to the next tooling station 23, waiting for manual unloading. At this time, the receiving assembly 3 at the second station 232 is transferred to the first station 231. The movement process is driven by the second ejection assembly 6 to lift slightly upward, so that there is a gap between the receiving assembly 3 at the second station 232 and the conveying assembly 2, so that the robotic arm assembly 4 can clamp the receiving assembly 3 and move it to the first station 231. Then, the next set of receiving assemblies 3 arranged parallel to the second station 232 in the X-axis direction will move to the second station 232 under the drive of the conveying assembly 2 to wait for the next round of receiving. This cycle is repeated to realize the automatic receiving of PCB board materials. The process is fully automated, which makes the quality and efficiency of unloading higher, saves manpower, and improves safety.

[0033] Specifically, such as Figure 3 As shown, the receiving assembly 3 includes a base plate 31, a support plate 32, and four limiting posts 33 respectively disposed on the top corners of the base plate 31. The support plate 32 is located above the base plate 31 and has a smaller area than the base plate 31. The support plate 32 is disposed within the inner top corners of each of the limiting posts 33, and together with each of the limiting posts 33, forms a material placement frame. The limiting posts 33 have a certain height along the Z-axis, which serves to limit the material when it is placed on the support plate 32, preventing the material from falling from both sides of the support plate 32. At the same time, it also allows the receiving assembly 3 to continuously stack more material, increasing the material receiving capacity and reducing the frequency of manual unloading, thereby improving production efficiency. To facilitate manual movement of the receiving assembly 3, handles 312 are screwed onto both sides of the base plate 31 along the Y-axis.

[0034] Furthermore, such as Figure 4-5As shown, the first ejector assembly 5 includes a first fixed plate 51 and a first support plate 52. The first fixed plate 51 is fixedly connected to the frame 1, and the first support plate 52 abuts against the base plate 31 of the receiving assembly 3. A first driving member 53 and a lead screw 54 are provided at the center of the first fixed plate 51. The first driving member 53 includes a motor 531, a driving wheel 532, a driven wheel 533, and a synchronous belt 534 that works in conjunction with the driving wheel 532 and the driven wheel 533. The output shaft of the motor 531 passes through the first fixed plate 51 and is fixedly connected to the driving wheel 532. The rotation of the driving wheel 532 can drive the driven wheel 533 to rotate. The driven wheel 533 is fixedly connected to one end of the lead screw 54, and the other end of the lead screw 54 is fixedly connected to the first support plate 52. Therefore, under the drive of the motor 531, the lead screw 54 can move up and down, thereby driving the first support plate 52 and the receiving assembly 3 located on the first support plate 52 to move up and down. To improve the balance and stability of the first support plate 52, a plurality of guide rods 55 are provided on the first fixed plate 51. One end of the guide rod 55 is fixedly connected to the first support plate 52, and the other end is slidably connected to the first fixed plate 51.

[0035] Furthermore, two alignment pins 521 are fixed on the upper surface of the first support plate 52, and the base plate 31 is provided with alignment holes 311 corresponding to the alignment pins 521. When the base plate 31 abuts against the first support plate 52, the alignment pins 521 pass through the alignment holes 311 and extend outside the alignment holes 311, thereby forming a limiting and fixing effect on the back and forth action of the base plate 31, enhancing the stability of the position of the base plate 31, and making the base plate 31 and the first support plate 52 only move up and down to separate. The alignment pins 521 are conical and have a guiding effect on the insertion of the alignment holes 311. It should be noted that a plurality of support plates 34 are provided between the base plate 31 and the support plate 32, which are perpendicular to the base plate 31. The two ends of the support plates 34 abut against the base plate 31 and the support plate 32 respectively, so that there is a certain space between the base plate 31 and the support plate 32. When the alignment pin 521 passes through the base plate 31, it will not affect the support plate 32. In addition, the support plate 32 is also provided with through holes 321 corresponding to the two alignment pins 521. The through holes 321 make it easy to observe whether the positions of the alignment holes 311 and the alignment pins 521 correspond, thereby improving the accuracy and efficiency of the engagement of the receiving component 3 and the first ejection component 5.

[0036] Preferably, the lower end face of the first support plate 52 is also provided with two proximity switches 523, and the frame 1 is also provided with a display screen (not shown in the figure) for controlling the operation of each component. The proximity switches 523 are used to detect whether the receiving component 3 is in contact with the first ejection component 5, so as to make the first driving member 53 move downward to perform the receiving step.

[0037] Preferably, the first fixed plate 51 is further provided with a sensor 511, and the lower end surface of the first support plate 52 is provided with a sensing plate 522 that works in conjunction with the sensor 511. When the first support plate 52 is lowered to the lowest height under the drive of the first drive member 53, the sensor 511 will issue an early warning when it senses the sensing plate 522. At this time, the first drive member 53 stops operating, and the receiving component 3 just lands on the conveying component 2.

[0038] Furthermore, such as Figure 6-7 As shown, in this embodiment, the conveying assembly 2 includes a first conveying track 21 and a second conveying track 22 that move along the X-axis. The first conveying track 21 includes a plurality of rollers 211 disposed on both sides of the frame 1. A conveyor belt 212 is wound around each of the rollers 211 on the same side. The receiving assembly 3 is placed on the two conveyor belts 212. A third driving member 213 is also provided inside the frame 1. The third driving member 213 is used to drive the rollers 211 to rotate so as to drive the conveyor belts 212 to rotate. The first support plate 52 moves up and down between the two conveyor belts 212. The second conveying track 22 includes a plurality of transmission rollers 221 spaced apart along the X-axis. Adjacent transmission rollers 221 are connected to the first conveying track 212. The moving rollers 221 are connected end-to-end. The receiving assembly 3 is placed on the transmission roller 221. The frame 1 is also equipped with a fourth driving member 222, which drives the transmission roller 221 to rotate, thereby driving the receiving assembly 3 to switch positions on the second conveying track 22. To increase the rotational speed of the transmission roller 221, multiple fourth driving members 222 can be provided. In this embodiment, there are 4 tooling positions 23 and 2 fourth driving members 222. If there is no space limitation, multiple tooling positions 23 can be provided, thereby reducing the time for manual material handling, improving the efficiency of material unloading, and preventing the machine from operating normally when material handling is not timely. At the same time, to ensure the accuracy of the conveying position of the receiving assembly 3 during conveying, at least one end of the conveying direction of the tooling position 23 is equipped with an optical fiber sensor 214 to prevent the receiving assembly 3 from colliding with each other or falling off due to excessive conveying distance during the conveying process.

[0039] Furthermore, such as Figure 8As shown, since the receiving component 3 on the second station 232 needs to move towards the first station 231 under the clamping of the robot arm component 4, in order to facilitate the clamping of the robot arm component 4, the present invention provides a second ejection component 6 so that the receiving component 3 located on the second station 232 can move slightly upward so that the robot arm component 4 has clamping space. The second ejection assembly 6 includes a second driving member 61, a second fixing plate 62, and a second support plate 63. The second fixing plate 62 is fixedly connected to the frame 1. The second driving member 61 is fixed on the second fixing plate 62, and its output shaft passes through the second fixing plate 62 and connects to the second support plate 63. Since the second conveying track 22 is composed of multiple spaced transmission rollers 221, the second support plate 63 is provided with two support frames 631 parallel to the transmission rollers 221. The two support frames 631 pass through the gap between two adjacent transmission rollers 221 and abut against the bottom plate 31 of the receiving assembly 3. The support frame 631 is also provided with an alignment pin 521 corresponding to the alignment hole 311 on the receiving assembly 3 and a proximity switch 523. The functions of the alignment pin 521 and the proximity switch 523 are the same as those on the first ejection assembly 5, and will not be repeated here. The second driving member 61 is a cylinder.

[0040] Further into one place, such as Figure 9 As shown, the robotic arm assembly 4 includes two guide rails 41 that move along the Y-axis and a connecting rod 42. The two ends of the connecting rod 42 are slidably connected to the two guide rails 41 respectively. The lower end surface of the connecting rod 42 is provided with two robotic arms 43. The two robotic arms 43 are used to clamp the two ends of the receiving assembly 3 and move from the second station 232 to the first station 231 under the action of the guide rails 41 to continue the next round of receiving. The whole process is mechanically automated, which saves more time and effort.

[0041] Preferably, such as Figure 6 , 10 As shown, a trolley 24 can also be provided at the discharge end of the conveying component 2. The frame 1 is provided with a pin 25 for fixing the trolley 24. The trolley 24 is engaged with the pin 25 to prevent the trolley 24 from moving under force, thereby facilitating the transfer of the receiving component 3 from the conveying component 2 to the trolley 24, and then to other processing sites or for unloading. This makes the material transfer process safer and more convenient, and the operation simpler. Only one worker is needed to complete the task, saving time and effort.

[0042] The working principle of this utility model is explained in detail below:

[0043] During material receiving, the receiving assembly 3 is first placed on the first station 231. The first driving member 53 drives the receiving assembly 3 to move upward and connect with the feeding station 71 to complete the material docking. During this process, the first driving member 53 will gradually descend until the material is stacked to the maximum amount that the receiving assembly 3 can bear. At this time, the first driving member 53 stops driving and moves downward, causing the alignment pin 521 to disengage from the alignment hole 311, so that the receiving assembly 3 carrying the material can move along the X-axis direction on the conveyor belt 212 to its adjacent... The tooling position 23 moves; then, the receiving component 3 on the second work station 232 moves slightly upward, so that the two robotic arms 43 can clamp and move towards the first work station 231, and connect the clamped receiving component 3 to the first ejection component 5 to continue receiving material; at the same time, the second ejection component 6 moves downward, and the receiving component 3 on the tooling position 23 adjacent to the second work station 232 is transferred to the second work station 232, and so on, to realize the automation of receiving material, thereby improving production efficiency.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
