Description

Technical Field

[0001] This utility model relates to the field of circuit board mounting technology, and specifically to a circuit board mounting device. Background Technology

[0002] In the electronics manufacturing industry, circuit boards are core components of various electronic devices. The efficiency and stability of their production, transportation, and subsequent processing directly affect the production rhythm of the entire electronics supply chain. After production, circuit boards need to be stored in trays to facilitate subsequent storage, testing, and assembly processes.

[0003] In existing technologies, it is usually necessary to manually unload and stack trays full of circuit boards. This is not only labor-intensive and inefficient, but also makes it difficult to ensure that the placement of each layer of trays is accurately aligned. This can easily lead to problems such as stacking tilting and collapse, which not only affects the rational use of storage space, but may also cause secondary damage to the circuit boards in the trays.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0022] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0023] In the field of circuit board manufacturing, reference Figure 2 As shown, a tray U is typically used to load circuit boards W to complete the transfer of circuit boards W. The tray U has a structure with several grooves U2 for loading circuit boards W.

[0024] The traditional process of assembling circuit boards (PCBs) typically involves manual tray separation, manual tray assembly, and manual unloading, which is inefficient.

[0025] This application provides a circuit board processing apparatus 100, with reference to... Figure 1 and Figure 2 As shown, the device can automatically feed and separate material trays U and automatically load and stack circuit boards W. The circuit board processing equipment 100 includes a feeding assembly 1, a tray loading assembly 2, a first conveying assembly 3, a receiving assembly 4, a second conveying assembly 5, and a third conveying assembly 6. The feeding assembly 1 includes a accommodating space 11 and a tray separating device 12 disposed on one side of the accommodating space 11. Several trays U are stacked in the accommodating space 11. The tray separating device 12 is used to separate the bottom trays from other trays. The loading assembly 2 is located on one side of the feeding assembly 1. The loading assembly 2 is configured to place the circuit board W in the tray when the separated trays are located in the loading assembly 2. The first conveying assembly 3 is used to convey the bottom trays separated by the tray separating device 12 in the feeding assembly 1 to the loading assembly 2. The receiving assembly 4 is located below the loading assembly 2 and is configured to receive several full-load trays that have been loaded in the loading assembly 2 and stack several full-load trays. The second conveying assembly 5 is located between the loading assembly 2 and the receiving assembly 4 and is used to convey the full-load trays that have been loaded with circuit board W in the loading assembly 2 to the receiving assembly 4 in sequence. The third conveying assembly 6 is used to unload several full-load trays that have reached a preset height on the receiving assembly 4.

[0026] Understandably, through the collaborative design of the feeding component 1, the tray loading component 2, the first conveying component 3, the second conveying component 5, the third conveying component 6, and the receiving component 4, the entire process of loading circuit board W into a fully automated closed loop is achieved. On the one hand, the tray separating device 12 automatically separates the stacked trays, and the first conveying component 3 accurately delivers empty trays, solving the problems of low efficiency and positioning deviation in traditional manual feeding. On the other hand, the receiving component 4 automatically stacks full-load trays U, and the third conveying component 6 unloads in batches, solving the problems of single-tray storage and manual unloading during machine downtime in traditional equipment, thus reducing labor costs and operational errors while ensuring production continuity.

[0027] For details, please refer to Figure 2As shown, the tray separating device 12 includes a work frame 121, a fixing component 122, and a tray separating component 123. The fixing component 122 includes at least four guard plates 1221 and a connecting plate 1222. The fixing component 122 is rectangularly mounted on the work frame 121. The four guard plates 1221 surround the aforementioned accommodating space 11. A plurality of stacked trays U are accommodated in the accommodating space 11. The trays U have edge portions U1, and the edge portions U1 of the trays U overlap the work frame 121. The tray separating component 123 is disposed on the connecting plate 1222 and includes a driving member 1231 and a separating plate 1232 connected to the driving member 1231. The tray separating component 123 is configured such that the driving member 1231 can drive the separating plate 1232 to insert between the bottom tray and the tray above the bottom tray in the stacked trays to separate the bottom tray from other trays. The first conveying component 3 drives the bottom tray separated from other trays U to move.

[0028] Understandably, the four guard plates 1221 of the fixing component 122 form an accommodating space 11, which can limit the stacked trays and prevent them from tipping over; the tray separating component 123 drives the separating plate 1232 to be directly inserted between the bottom tray and the upper tray through the driving component 1231, so as to separate the bottom tray in sequence; the first conveying component 3 is located below the trays and can directly receive and transfer the separated bottom trays without manual intervention or additional transfer steps, which greatly improves the tray separating efficiency, and the whole process does not require hand contact with the trays, which can meet the cleanliness requirements of electronic components.

[0029] For more specific details, please refer to Figure 2 and Figure 4 As shown, the driving component 1231 includes a first cylinder 12311 arranged in the vertical direction and a second cylinder 12312 arranged in the horizontal direction. The second cylinder 12312 is connected to the first cylinder 12311 and is also connected to the material distribution plate 1232. The driving component 1231 is configured such that the first cylinder 12311 drives the second cylinder 12312 and the material distribution plate 1232 to move to the top of the bottom material tray. After the material distribution plate 1232 is inserted into the bottom material tray and the material tray above the bottom material tray, the first cylinder 12311 drives the second cylinder 12312 and other material trays to move upward.

[0030] Understandably, the first cylinder 12311 first drives the second cylinder 12312 and the material distribution plate 1232 to move to the top of the bottom tray, ensuring that the material distribution plate 1232 can be accurately aligned with the edge U1 of the tray above the bottom tray. After the material distribution plate 1232 is inserted, the first cylinder 12311 then drives the second cylinder 12312 and the upper tray to lift upwards, which can completely separate the bottom tray from other trays and avoid damage to the edge U1 of the tray due to excessive force when the material distribution plate 1232 is inserted. At the same time, the coordinated action of the horizontal and vertical cylinders can adapt to trays of different thicknesses, eliminating the need for frequent adjustment of equipment parameters and improving the versatility and operational flexibility of the device.

[0031] In this embodiment, four tray-splitting components 123 are provided, with two tray-splitting components 123 forming a group, and the two groups of tray-splitting components 123 are located on both sides of the stacked tray.

[0032] Understandably, symmetrical multi-point drive effectively solves the problem of tray tilting and separation failure caused by uneven force distribution in traditional tray separating components. The synchronous operation of the symmetrical tray separating components 123 on both sides can apply force evenly from both sides of the tray, avoiding unilateral offset or jamming of the tray when the separating plate 1232 is inserted; at the same time, multi-point support can distribute the weight of the stacked trays above, reducing the load pressure on the separating plate 1232, and the symmetrical structure can further improve the stability of the tray separating process.

[0033] Further, refer to Figure 2 and Figure 3 As shown, the tray separating device 12 also includes a limiting component 124 disposed on the work frame 121. The limiting component 124 is configured such that after the bottom tray is clamped and fixed, the separating plate 1232 is inserted between the bottom tray and the tray above the bottom tray.

[0034] Understandably, the limiting component 124 clamps and fixes the bottom tray before the material distribution plate 1232 is inserted, which can ensure that the bottom tray remains stationary and prevent the bottom tray from moving upward due to the friction between the trays when the material distribution plate 1232 is inserted, thereby achieving complete separation of the bottom tray from the upper tray.

[0035] In this embodiment, the work frame 121 is provided with a notch 1211 flush with the edge of the bottom tray; the limiting component 124 includes a third cylinder 1241 and a pressure plate 1242 connected to the third cylinder 1241, the third cylinder 1241 can drive the pressure plate 1242 to extend into the notch 1211 so as to be located above the edge of the bottom tray.

[0036] Understandably, by pressing down and limiting the bottom material tray edge U1 with the pressure plate 1242, the bottom material tray can be quickly fixed, and the pressure plate 1242 can be prevented from directly contacting the area of ​​the material tray that carries the material, thus protecting the material from damage.

[0037] In this embodiment, reference Figure 2 As shown, the tray separating device 12 also includes a detection structure 125 installed on the work frame 121. The detection structure 125 is used to detect the bottom tray to determine whether the bottom tray is in place. For example, when the controller receives the detection signal from the detection structure 125, the tray separating component 123 performs the tray separating operation. When the controller does not receive the detection signal from the detection structure 125, it issues an alarm. At this time, there are two situations: the first situation is that there is no tray in the accommodating space 11, and the staff needs to replenish the material to continue the tray separating operation; the second situation is that the stacked trays are stuck, and the staff needs to perform maintenance operations. This realizes the automated control of separating trays when there are trays and issuing an alarm when there are no trays, reducing the frequency of manual inspection, reducing labor costs, and avoiding energy waste caused by idling without trays.

[0038] Further, refer to Figure 2 and Figure 5 As shown, the first conveying assembly 3 includes a first power member 31, a transmission member 32 connected to the first power member 31, and a pusher plate 33 connected to the transmission member 32. The first power member 31 can drive the transmission member 32 to drive the pusher plate 33 to move the bottom tray, so that the bottom tray has a first position and a second position. When in the first position, the bottom tray is located below the stacked trays. When in the second position, the orthographic projection of the stacked trays does not overlap with the bottom tray.

[0039] Understandably, the pusher plate 33 can move between the first position and the second position. The separated bottom tray falls directly onto the pusher plate 33. The first power component 31 drives the pusher plate 33 to be quickly transferred to the next station through the transmission component 32. No manual intervention is required, which greatly improves the continuous operation efficiency of the production line.

[0040] In this embodiment, the first conveying component 3 further includes a guide rail 34 disposed between the first position and the second position, and a slider adapted to the guide rail 34 is connected below the push plate 33. The guide rail 34 is disposed between the first position and the second position, and the slider is connected to the bottom of the push plate 33 and adapted to the guide rail 34, which can provide precise guidance for the movement of the push plate 33, avoid the push plate 33 from shifting left and right or bouncing up and down during the transfer process, and ensure that the bottom tray remains stable during the transfer process.

[0041] In this embodiment, reference Figure 1 As shown, the receiving component 4 is located below the loading component 2, and the second conveying component 5 can move up and down to convey the full-loaded tray on the loading component 2 to the receiving component 4.

[0042] Understandably, this setup has several advantages. First, by placing the receiving component 4 below the loading component 2, it eliminates the need for additional horizontal space, significantly saving the overall footprint of the equipment. Second, this layout makes the transfer of fully loaded trays more efficient. The second conveying component 5 can directly receive the tray from below the loading component 2 and convey it downwards to the receiving component 4, eliminating the need for long-distance horizontal transfers, shortening the tray transfer path, reducing transfer time, and avoiding the risk of the tray tipping over or the circuit board W falling during horizontal transfers, thus improving the safety and efficiency of transferring fully loaded trays.

[0043] Further, refer to Figure 1 , Figure 6 as well as Figure 7 As shown, the tray loading assembly 2 also includes a second power member 21 disposed on both sides of the bottom tray and a support plate 22 connected to the second power member 21. The second power member 21 is used to drive the support plate 22 to move relative to each other or move away from each other to have a support position and a tray dropping position. When in the support position, at least part of the orthographic projection of the tray on the tray loading assembly 2 overlaps with the support plate 22, that is, the distance between the two support plates 22 is less than the width of the tray, thereby supporting the tray so as to facilitate the installation of the circuit board W in the tray. When in the tray dropping position, the orthographic projection of the tray on the tray loading assembly 2 does not overlap with the support plate 22. At this time, the distance between the two support plates 22 is greater than the width of the tray, so that the tray can fall on the second conveying assembly 5, thereby realizing the automated connection of tray loading and tray dropping.

[0044] Furthermore, the tray loading assembly 2 also includes a third power member 23 and a limiting plate 24 connected to the third power member 23, the third power member 23 being able to drive the limiting plate 24 to approach or move away from the tray on the support plate 22.

[0045] Understandably, the limiting plate 24 can move closer to or further away from the tray under the drive of the third power component 23. Before the circuit board W is loaded, the limiting plate 24 can abut against the edge of the tray to perform secondary positioning of the tray, ensuring that the position of the tray on the tray assembly 2 is completely fixed, and avoiding the circuit board W being placed in the wrong position due to slight displacement of the tray.

[0046] In this embodiment, reference Figure 6 As shown, the tray loading assembly 2 also includes a first detection element 25, a second detection element 26, and a third detection element 27. Specifically, when a tray is present on the tray loading assembly 2, the first detection element 25 is positioned within the thickness range of the tray, the second detection element 26 is positioned below the tray, and the third detection element 27 is positioned below the second detection element 26.

[0047] Understandably, the first detection element 25 is located at the end of the tray loading assembly 2 away from the feeding assembly 1 and is arranged along the width direction to detect whether the tray has been pushed into place by the push plate 33; the second detection element 26 and the third detection element 27 cooperate to detect the dropping of the tray on the tray loading assembly 2; if the second detection element 26 does not detect the presence of a tray and the third detection element 27 detects the presence of a tray, it means that the tray has successfully dropped onto the second conveying assembly 5. By setting the second detection element 26 below the tray and the third detection element 27 below the second detection element 26, the gap between the dropped tray and the tray that has not dropped above is small enough to reduce the drop difference of the tray, thereby reducing the vibration and damage of the product.

[0048] In this embodiment, reference Figure 1 and Figure 8 As shown, the receiving component 4 includes a receiving plate 41 disposed on the third conveying component 6 and a limiting post 42 disposed at the corner of the receiving plate 41. The receiving plate 41 is used to receive several stacked full-load trays. The limiting post 42 is located around the several stacked full-load trays, and the height of the several stacked full-load trays is lower than the height of the limiting post 42, so as to limit the several stacked full-load trays on the receiving component 4 and prevent the stacked full-load trays from shaking or shifting.

[0049] Furthermore, the second conveying assembly 5 includes a fourth power member 51 and a tray 52 connected to the fourth power member 51. The tray 52 is used to hold a full-load tray on the tray loading assembly 2. The fourth power member 51 is capable of driving the tray 52 to move between the tray loading assembly 2 and the receiving assembly 4.

[0050] Understandably, the pallet 52 can fully support the fully loaded pallet from the bottom, thus distributing the force on the pallet and preventing deformation caused by excessive local force on the pallet.

[0051] Furthermore, the receiving plate 41 is provided with a clearance area 411, and the area of ​​the pallet 52 is smaller than the clearance area 411. The fourth power component 51 can drive the pallet 52 to descend through the clearance area 411 to below the receiving plate 41, so that the full-load pallet on the pallet 52 is placed on the receiving plate 41.

[0052] Understandably, when the pallet 52 lowers the fully loaded tray to the position of the receiving plate 41, it can directly descend through the clearance area 411 to the bottom of the receiving plate 41. At this time, the tray naturally falls onto the receiving plate 41 because it loses the support of the pallet 52. There is no need for additional pallet 52 removal action, which simplifies the tray dropping process, shortens the single tray dropping time, and improves the stacking efficiency of the receiving component 4. At the same time, it avoids friction and collision between the pallet 52 and the receiving plate 41, reduces component wear, and the tray is placed stably only under the action of gravity during the dropping process, without external force pulling, which further ensures the integrity of the tray and the circuit board W and reduces the failure risk of the dropping process.

[0053] Furthermore, the equipment also includes a discharge port 7 and a fourth detection element 71 disposed on the discharge port 7. The third conveying component 6 can drive the receiving component 4 to move to the discharge port 7, thereby facilitating the removal of the stacked full pallet by the external forklift structure.

[0054] Understandably, by setting a fourth detection element 71 on the discharge port 7, it can prevent workers from reaching into the discharge port 7 and causing danger; on the other hand, it can also detect that the stacked full pallet has reached the discharge port 7, reminding workers to remove it using a forklift.

[0055] It should be noted that in this embodiment, the driving method of the fourth power component 51 can be a combination of single-stage stroke driving and multi-stage intermittent stroke driving. When the tray 52 is used to support the first tray mounted on the circuit board W on the tray assembly 2, the tray 52 is located below the tray assembly 2. When the second tray needs to be placed, the fourth power component 51 drives the tray 52 to descend a preset distance using multi-stage intermittent stroke driving, so that the second tray falls on top of the first tray on the tray 52. ​​This process is repeated to place several trays until the trays stacked on the tray 52 reach the target height. Then, the fourth power component 51 drives the tray 52 to move the stacked trays downwards using single-stage stroke driving until the stacked trays are placed on the receiving plate 41. In this embodiment, the preset distance of the multi-stage intermittent stroke driving of the fourth power component 51 is the thickness of one tray.

[0056] As described above, the process of mounting the circuit board W on a tray is as follows: first, several stacked trays are divided into individual trays, and then the individual trays are transferred to the tray mounting assembly 2 for mounting the circuit board W. The circuit board W is placed in several grooves U2 of the tray in sequence, and then the trays containing the circuit board W are stacked and unloaded.

[0057] However, in actual production, abnormal situations can easily occur during the stacking of empty trays, affecting subsequent processes. For example... Figure 11 As shown, the abnormal stacking of two adjacent trays, placed in opposite directions, will affect the stacking of subsequent trays containing circuit boards W. When two adjacent trays are abnormally stacked, they are oriented in the same direction. This will lead to the following problems: First, it will be difficult to separate the trays. Second, after loading circuit boards W onto two oriented trays, during stacking, the grooves U2 at the same position in the two adjacent trays will overlap, causing the groove U2 at the same position in the upper tray to squeeze the circuit board W in the groove U2 at the same position in the lower tray. In the event of a material shortage, it will cause subsequent tray separation, circuit board W loading, and stacking to become disordered or result in unstable stacking.

[0058] To solve the aforementioned technical problems, the circuit board processing equipment 100 of this application also includes a tray detection device, as shown in the reference. Figure 2 , Figure 9 and Figure 10 As shown, the tray detection device is used to detect stacked trays before they are separated, so as to detect stacking abnormalities in advance and issue an early warning, so that staff can deal with abnormal stacking in advance, thereby avoiding problems in subsequent circuit board loading and stacking processes from the root.

[0059] In this embodiment, reference Figure 9 and Figure 10 As shown, the trays are roughly rectangular in shape, each tray having a notched corner U11 and a first solid corner U12 and two other second solid corners U13 diagonally opposite the notched corner U11. The notched corner U11 has a notch and a stepped surface U111 protruding from the notch. Several trays are stacked in a reversed arrangement.

[0060] In this embodiment, the accommodating space 11 has a first corner 111 and a second corner 112 diagonally opposite to the first corner 111. At the first corner 111 or the second corner 112, a number of trays are stacked in the accommodating space 11 in an alternating manner with notched corners U11 and first solid corners U12.

[0061] For ease of understanding, the tray at the top is defined as the first tray, and the tray at the bottom is defined as the second tray. There are two cases when stacking. The first case is: the notched corner U11 of the first tray is located at the first corner 111, and the first solid corner U12 is located at the second corner 112. The first solid corner U12 of the second tray is located at the first corner 111, and the notched corner U11 is located at the second corner 112. Alternatively, the second case is: the first solid corner U12 of the first tray is located at the first corner 111, and the notched corner U11 is located at the second corner 112. The notched corner U11 of the second tray is located at the first corner 111, and the first solid corner U12 is located at the first corner 111.

[0062] After being stacked in either of the two methods described above in the accommodating space 11, in the process of loading the circuit board W, the second tray and the first tray are sequentially separated by the tray-separating device 12 and transported to the circuit board W loading station in sequence. After the circuit board W is loaded, it is stacked in the same way as the stacking method in the accommodating space 11, and finally the unloading is achieved.

[0063] In this embodiment, reference Figure 2 and Figure 11 As shown, the material tray detection device includes a detection component 8, which is mounted on the work frame 121 and includes at least a first sensor 81, a second sensor 82, a third sensor 83 located on the first corner 111, a fourth sensor 84 located on the second corner 112, and a fifth sensor 85.

[0064] In this embodiment, for ease of description, the relative heights of different parts of the tray in different states are defined as follows: the height of a single tray is the first preset height H1; the height of the step surface U111 is the second preset height H2; when two adjacent trays are stacked in the same direction, the distance between the bottoms of the two trays is the third preset height H3; the distance from the top of the step surface U111 of the upper tray to the bottom of the lower tray is the fourth preset height H4 (H2+H3); and the distance from the top of the upper tray to the bottom of the lower tray is the fifth preset height H5 (H1+H3).

[0065] In this embodiment, the first sensor 81 and the fourth sensor 84 are disposed on the same horizontal plane and located between the third preset height H and the fourth preset height H4 (H2+H3). The second sensor 82 is located between the fourth preset height H4 (H2+H3) and the first preset height H1. The third sensor 83 and the fifth sensor 85 are disposed on the same horizontal plane and located between the first preset height H and the fifth preset height H5 (H1+H3).

[0066] Understandably, by setting the positions of the first sensor 81, the second sensor 82, the third sensor 83, the fourth sensor 84, and the fifth sensor 85 in the above manner, the material trays within the detection range corresponding to the detection component 8 can be detected to determine the state of the material trays within the detection range. For example, the detection signal of the detection component 8 can be used to determine whether the placement direction of two adjacent material trays within the detection range is correct, whether two adjacent material trays have abnormal stacking, and whether the material trays within the detection range are exhausted and need to be replenished.

[0067] Furthermore, in this embodiment, the first sensor 81, the second sensor 82, the third sensor 83, the fourth sensor 84, and the fifth sensor 85 are all infrared through-beam sensors. These infrared through-beam sensors can transmit the through signal passing through the notch angle U11 to the controller, or the blocking signal after being blocked by the first solid angle U12 to the controller. In this embodiment, the state of the tray within the detection range is determined by combining the signals from multiple infrared through-beam sensors.

[0068] Further, refer to Figure 2 As shown, the protective plate 1221 has a through hole 12211 along the height direction. The connecting wires of the transmitting end and the receiving end of any of the sensors pass through the through hole 12211, so that several sensors can be installed stably without affecting the detection.

[0069] Furthermore, the detection component 8 also includes a mounting bracket 86 disposed at the first corner 111 and the second corner 112, and the sensor is detachably mounted on the mounting bracket 86 to facilitate the installation and removal of several sensors.

[0070] Furthermore, a plurality of adjustment plates (not shown) are slidably disposed on the mounting bracket 86 along the height direction, and each adjustment plate corresponds to a sensor, with the sensor mounted on the adjustment plate.

[0071] Understandably, by installing sensors one-to-one with sliding adjustment plates, the positions of several sensors can be adjusted for different thicknesses of trays, thus enhancing versatility.

[0072] This application also provides a method for processing a circuit board W, which uses the circuit board processing equipment 100 described above, and the steps of the method include: Several stacked empty trays are stacked in the accommodating space 11 with the notched corner U11 and the first solid corner U12 interleaved. Multiple sensors in detection component 8 detect the stacked empty trays within the detection range and output detection signals; The controller determines the state of the stacked trays within the detection range based on the combination of detection signals output by the detection component 8. If the combination of detection signals output by detection component 8 is normal, the circuit board W processing flow continues. If the combination of detection signals output by detection component 8 is abnormal, the controller will issue a warning signal.

[0073] Furthermore, the controller determines the state of the stacked trays within the detection range based on the combination of detection signals output by the detection component 8, including: If the detection signals of the first sensor 81 and the second sensor 82 are the same and opposite to the detection signal of the fourth sensor 84, and the third sensor 83 and the fifth sensor 85 are both occlusion signals, then the orientation of the two adjacent trays within the detection range is correct.

[0074] Understandably, if the signal received by the controller from the detection component 8 is the same as the detection signal of the first sensor 81 and the second sensor 82 and opposite to the detection signal of the fourth sensor 84, and the third sensor 83 and the fifth sensor 85 are both occlusion signals, then the two adjacent trays within the detection range are correctly positioned, and the controller controls the stacked trays to continue the process of tray splitting, tray loading, and stacking.

[0075] Furthermore, the controller determines the state of the stacked trays within the detection range based on the combination of detection signals output by the detection component 8, including: If the detection signals of the first sensor 81 and the second sensor 82 are the same and opposite to the detection signal of the fourth sensor 84, and the third sensor 83 and the fifth sensor 85 are both through signals, then there is only one material tray in the detection range.

[0076] Understandably, if the signal received by the controller from the detection component 8 is the same as the detection signal of the first sensor 81 and the second sensor 82 and opposite to the detection signal of the fourth sensor 84, and the third sensor 83 and the fifth sensor 85 are both through signals, then there is only one material tray in the detection range. At this time, the controller issues a warning signal to remind the staff to replenish the material in time.

[0077] It should be noted that in this embodiment, the combination of detection signals of detection component 8 is determined to be abnormal except for the two cases mentioned above.

[0078] Furthermore, in this embodiment, various abnormal conditions of the tray within the detection range can be determined by combining two detection signals.

[0079] In this embodiment, the controller determines the state of the stacked trays within the detection range based on the combination of detection signals output by the detection component 8, including: If the detection signal received by the controller does not meet the condition that the detection signals of the first sensor 81 and the second sensor 82 are the same and opposite to the fourth detection signal, then the material tray stacking within the detection range is abnormal. Alternatively, if the detection signals of the third sensor 83 and the fifth sensor 85 are opposite, then the material tray stacking within the detection range is abnormal.

[0080] Understandably, any abnormality in the material tray within the detection range can be detected through at least one of the two methods mentioned above.

[0081] Understandably, by setting two methods for detecting anomalies, the inability to detect anomalies when a sensor malfunctions in one of the detection methods can be avoided. For example, in one embodiment, if any one of the first sensor 81, the second sensor 82, or the fourth sensor 84 malfunctions and fails to emit a detection signal or emits an incorrect detection signal, the anomaly can still be determined by the third sensor 83 and the fifth sensor 85; in another embodiment, if any one of the third sensor 83 or the fifth sensor 85 malfunctions and fails to emit a detection signal or emits an incorrect detection signal, the anomaly can still be determined by a combination of the detection signals from the first sensor 81, the second sensor 82, and the third sensor 83.

[0082] The following will provide a detailed description of the correct placement of the material tray, the need for material replenishment, and various abnormal situations.

[0083] As described above, when the trays are placed correctly, there are two stacking situations as described above.

[0084] When in the first stacking case, refer to Figure 12 As shown, the detection signals of the first sensor 81 and the second sensor 82 are both pass signals, and the detection signal of the fourth sensor 84 is an obstruction signal. At this time, since the fifth sensor 85 corresponds to the step surface U111 of the first material tray, the detection signals of the third sensor 83 and the fifth sensor 85 are both obstruction signals. In this case, it is determined that the material tray within the detection range is placed correctly.

[0085] When in the second stacking case, refer to Figure 13 As shown, the first sensor 81 and the second sensor 82 are both blocking signals, and the detection signal of the fourth sensor 84 is a passing signal. At this time, since the third sensor 83 corresponds to the step surface U111 of the first material tray, the detection signals of the third sensor 83 and the fifth sensor 85 are also determined to indicate that the material tray within the detection range is correctly placed.

[0086] As described above, when the trays are placed correctly, there are two stacking situations as described above.

[0087] When in the first stacking case, refer to Figure 14 As shown, the detection signals of the first sensor 81 and the second sensor 82 are both through signals, the detection signal of the fourth sensor 84 is an obstruction signal, and the detection signals of the third sensor 83 and the fifth sensor 85 are both through signals. Therefore, it is determined that there is no material tray at the position corresponding to the third sensor 83 and the fifth sensor 85, that is, a material shortage state. The controller issues an early warning and provides material feeding.

[0088] When in the second stacking case, refer to Figure 15 As shown, the detection signals of the first sensor 81 and the second sensor 82 are both obstruction signals, the detection signal of the fourth sensor 84 is a pass signal, and the detection signals of the third sensor 83 and the fifth sensor 85 are both pass signals. Therefore, it is determined that there is no material tray at the position corresponding to the third sensor 83 and the fifth sensor 85, that is, a material shortage state. The controller issues an early warning and provides material feeding.

[0089] As described above, when the trays are placed correctly, there are two stacking situations as described above.

[0090] When in the first stacking case, refer to Figure 16 and Figure 18As shown, the first sensor 81, the fourth sensor 84, and the fifth sensor 85 all provide obstruction signals, while the second sensor 82 and the third sensor 83 provide passage signals. This indicates that two adjacent trays within the detection range are stacked in the same direction. It should be noted that in this case, the first sensor 81 should originally be detecting the notch angle U11 of the second tray, and the final detection signal would be a passage signal. However, due to the stacking in the same direction, the target detected by the first sensor 81 changes to the first tray, located at the same height as the step surface U111 of the first tray. This causes the detection signal of the first sensor 81 to change from a passage signal to an obstruction signal, and the other sensors also change accordingly.

[0091] When in the second stacking case, refer to Figure 17 and Figure 19 As shown, the first sensor 81, the second sensor 82, the third sensor 83, and the fourth sensor 84 are occlusion signals, and the fifth sensor 85 is a pass signal. This indicates that two adjacent trays within the detection range are stacked in the same direction. The principle is the same as the case of stacking trays in the same direction in the first stacking situation mentioned above.

[0092] As described above, when the trays are placed correctly, there are two stacking situations as described above.

[0093] When in the first stacking case, refer to Figure 20 As shown, the first sensor 81, the fourth sensor 84, and the fifth sensor 85 are all occlusion signals, while the second sensor 82 and the third sensor 83 are pass signals. Therefore, it is determined that three adjacent material trays are stacked within the detection range. The principle is the same as that of two adjacent material trays stacked in the same direction, which will not be elaborated here.

[0094] When in the second stacking case, refer to Figure 21 As shown, the first sensor 81, the second sensor 82, the third sensor 83, and the fourth sensor 84 are occlusion signals, and the fifth sensor 85 is a pass signal. This indicates that three adjacent material trays within the detection range are stacked in the same direction. The principle is the same as that of two adjacent material trays stacked in the same direction, which will not be elaborated here.

[0095] Furthermore, if the combination of detection signals output by the detection component 8 is normal, the circuit board W processing flow continues, including: The tray dividing assembly 123 divides several stacked empty trays sequentially from bottom to top; The first conveying component 3 conveys the empty material tray that has been divided to the tray loading component 2; Place the circuit board W in the groove U2 of the empty tray in the tray assembly 2; The second conveying component 5 supports the full-loaded tray on the loading component 2 after the circuit board W is loaded, and drives the full-loaded tray to move downwards multiple times to a preset distance in a multi-segment intermittent stroke drive manner. Once the full-loaded trays on pallet 52 reach the target height, the second conveying component 5 drives the stacked full-loaded trays downwards in a single-stroke drive manner until the receiving component 4 receives the stacked full-loaded trays.

[0096] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
