Description

Technical Field

[0001] The invention relates to the technical field of PCB manufacturing process, and in particular to a board placing machine. Background Art

[0002] PCB (Printed circuit boards) is the provider of electrical connections for electronic components. In the PCB manufacturing process, PCB boards usually need to be baked. The main purpose of baking PCB boards is to remove the moisture and humidity contained in the PCB boards or absorbed from the outside, so as to avoid problems such as delamination, expansion and bursting of the PCB boards. At the same time, baking can also stabilize the size of the PCB boards, improve the warping of the PCB boards, and improve product quality.

[0003] In the related art, a kielbasa rack is usually used to place PCB boards for baking. The PCB boards to be baked are laid flat on the mesh frame of the kielbasa rack, and then the kielbasa rack is placed on a baking cart. The kielbasa rack is sent into the oven by the movement of the baking cart. Due to the multi-layer design of the kielbasa rack, multiple PCB boards can be processed simultaneously in one baking, thereby greatly improving the baking efficiency. However, when placing or removing PCB boards on the kielbasa rack in the related art, the operator needs to flip and open the upper mesh frame before placing or removing the PCB boards on the lower mesh frame, which has the problems of complex operation, low safety and low production efficiency.

DETAILED DESCRIPTION

[0054] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0056] The following is combined with Figures 1 to 24 , the plate placing machine provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0057] See also Figure 1~Figure 4 The present application embodiment discloses a plate placing machine, and the disclosed plate placing machine includes a loading device and a taking device. Figure 2 As shown, the loading device includes a casserole rack 1000 and a lifting mechanism 2000. Figure 3 and Figure 4 As shown, the material taking device includes a conveying mechanism 4000, a clamping mechanism 6000, a driving mechanism 7000 and a lifting mechanism 8000, that is, the plate placing machine includes a tiered rack 1000, a lifting mechanism 2000, a conveying mechanism 4000, a clamping mechanism 6000, a driving mechanism 7000 and a lifting mechanism 8000.

[0058] In the embodiment of the present application, the lasagna rack 1000 is used to place a plurality of trays 5000. For example, the trays 5000 can be placed on the lasagna rack 1000 in a longitudinal stacking manner, and the PCB board can be placed on the trays 5000. For details, please refer to Figure 2 , Figure 5 and Figure 6 A plurality of longitudinally distributed slide grooves 1131 are provided on the lasagna rack 1000, and the plurality of slide grooves 1131 are extended along the first transverse direction. The material tray 5000 is slidably fitted in the slide grooves 1131. The material tray 5000 is used to carry the PCB board. The lifting mechanism 2000 is connected to the lasagna rack 1000 to lift the lasagna rack 1000 and move it upward to load the material.

[0059] In the embodiment of the present application, the conveying mechanism 4000 includes a plurality of conveying roller groups 4100 arranged in parallel, and the conveying roller groups 4100 are used to convey the PCB board. Figure 3The conveying roller group 4100 includes a roller shaft 4110 and a plurality of rollers 4120 disposed on the roller shaft 4110. When the PCB board is carried on the rollers 4120, the rollers 4120 rotate to convey the PCB board. In the embodiment of the present application, along the conveying direction of the conveying mechanism 4000, the lasagna rack 1000 is disposed on the first side of the conveying mechanism 4000, and the clamping mechanism 6000 is disposed on the second side of the conveying mechanism 4000. The first side and the second side are the left and right sides of the conveying direction of the conveying mechanism 4000.

[0060] In the examples of this application, see Figure 3 and Figure 4 The driving mechanism 7000 is connected to the clamping mechanism 6000, and the driving mechanism 7000 is used to drive the clamping mechanism 6000 to move between the first side and the second side, so as to clamp the material tray 5000 located on the first side and move it above the conveying roller set 4100. For example, a plurality of material trays 5000 are stacked in the lasagna rack 1000, and when the clamping mechanism 6000 clamps a material tray 5000, the driving mechanism 7000 can extract the material tray 5000 from the lasagna rack 1000 and move it above the conveying roller set 4100. For example, please continue to refer to Figure 3 The material tray 5000 includes a plurality of first cross bars 5100 and a plurality of second cross bars 5200. The plurality of first cross bars 5100 and the plurality of second cross bars 5200 are criss-crossedly connected to form a plurality of grid units 5300 in the material tray 5000. It can be understood that the area of ​​the PCB board is larger than the area of ​​any grid unit 5300, so that the PCB board can be stably supported on the first cross bars 5100 and the second cross bars 5200.

[0061] In the embodiment of the present application, the lifting mechanism 8000 is connected to the conveying mechanism 4000, and the lifting mechanism 8000 is used to drive the conveying roller set 4100 to move upward, so that the conveying roller set 4100 passes through the material tray 5000 and contacts the PCB board placed on the material tray 5000. Specifically, when the lifting mechanism 8000 lifts the conveying roller set 4100 to move upward, part of the roller 4120 in the conveying roller set 4100 can pass through the material tray 5000 through the grid unit 5300 and contact the PCB board above the material tray 5000, and the rotation of the roller 4120 can convey the PCB board, thereby realizing the separation of the PCB board from the material tray 5000, that is, realizing the removal of the PCB board.

[0062] Based on the above scheme, the driving mechanism 7000 drives the clamping mechanism 6000 to move between the first side and the second side to clamp the material tray 5000 in the lasagna rack 1000 and convey it to the top of the conveying roller group 4100. At this time, the lifting mechanism 8000 can lift the conveying roller group 4100 to move upward, so that part of the conveying roller group 4100 passes through the material tray 5000 and contacts the PCB board placed on the material tray 5000. In this way, the conveying roller group 4100 can convey the PCB board to the subsequent workstation. After the PCB board on the previous material tray 5000 is removed, the lifting mechanism 2000 can lift the lasagna rack 1000 to facilitate the clamping mechanism 6000 to clamp the next material tray 5000 with the PCB board placed on it. In this way, the automatic removal of multiple PCB boards in the lasagna rack 1000 can be realized, which has the characteristics of convenient operation and high safety.

[0063] At the same time, the lifting mechanism 8000 lifts part of the conveying roller group 4100 to pass through the material tray 5000 to contact the PCB board and realize the transportation of the PCB board, which effectively avoids the PCB board from sliding relative to the material tray 5000 and can reduce scratches or damage caused by friction. In addition, the lifting method also makes the contact pressure between the conveying roller group 4100 and the PCB board more uniform and gentle, thereby ensuring the safety of the PCB board during the removal and transfer process.

[0064] In the examples of this application, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The lasagna rack 1000 includes a supporting main frame 1100 and a comb plate 1200, wherein the supporting main frame 1100 is the basic component of the entire lasagna rack 1000, and can provide a bearing foundation for multiple material trays 5000, and can also provide an installation foundation for the comb plate 1200. Specifically, the supporting main frame 1100 is a frame-shaped structure as a whole, and the supporting main frame 1100 is provided with a plurality of longitudinally distributed slide grooves 1131 inside thereof, that is, a plurality of slide grooves 1131 are arranged on the inner side of the supporting main frame 1100, and a plurality of longitudinally distributed slide grooves 1131 are arranged on the opposite side walls of the supporting main frame 1100 and correspond to each other one by one, and the slide grooves 1131 are extended along the first transverse direction, and the aforementioned material trays 5000 can be slidably arranged in the slide grooves 1131.

[0065] In an embodiment of the present application, the lasagna rack 1000 has a feed end and a discharge end, and both ends of the slide groove 1131 extend to the feed end and the discharge end. The material tray 5000 can slide outward at the feed end to facilitate the operator to place the PCB board on the material tray 5000; similarly, the material tray 5000 can also slide out at the discharge end to facilitate the operator to remove the PCB board placed on the material tray 5000.

[0066] In the examples of this application, see Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The comb plate 1200 is disposed on the outer side of the supporting main frame 1100, and a plurality of comb teeth 1210 are disposed on the comb plate 1200. The comb plate 1200 has a first state and a second state, and the comb plate 1200 is movably disposed on the supporting main frame 1100 along the longitudinal direction to switch between the first state and the second state. In the first state, the comb teeth 1210 on the comb plate 1200 block the notch of the slide slot 1131. At this time, the comb teeth 1210 can play a role of limiting and blocking the material tray 5000 placed in the slide slot 1131, preventing the material tray 5000 from leaving the slide slot 1131; in the second state, the comb teeth 1210 on the comb plate 1200 are misaligned with the notch of the slide slot 1131, that is to say, at this time, the comb teeth 1210 of the comb plate 1200 avoid the notch of the slide slot 1131, and the notch of the slide slot 1131 is in an open state, and the material tray 5000 can slide outward through the notch of the slide slot 1131. When the material tray 5000 slides out of the slide slot 1131, a PCB board can be placed on the material tray 5000 or the PCB board placed on the material tray 5000 can be removed.

[0067] In the examples of this application, see Fig. 9 , Fig.10 , Fig.14 , Fig.15 and Fig.16 The comb plate 1200 has a portion protruding from the bottom of the supporting main frame 1100. The lifting mechanism 2000 includes a carrier plate 2100 and a lifting assembly 2200 connected to the carrier plate 2100. The lifting assembly 2200 is used to drive the carrier plate 2100 to rise or fall. The carrier plate 2100 is located below the supporting main frame 1100. The carrier plate 2100 and the supporting main frame 1100 at least partially overlap in the lateral direction of the lasagna rack 100. That is to say, the supporting main frame 1100 can be carried on the carrier plate 2100. When the lifting assembly 2200 drives the carrier plate 2100 to rise or fall, it can drive the supporting main frame 1100 to rise or fall.

[0068] In the embodiment of the present application, the lasagna rack 1000 is provided with comb plates 1200 at both the feeding end and the discharging end, wherein, see Fig.14 and Fig.15 , Fig.15 The relative position relationship between the bottom of the comb plate 1200 at the feeding end and the carrier plate 2100 is shown. Specifically, the part of the comb plate 1200 at the feeding end protruding from the bottom of the supporting main frame 1100 is staggered with the carrier plate 2100 along the lateral direction of the casserole rack 1000. Fig.14 and Fig.16 , Fig.16The relative position relationship between the bottom of the comb plate 1200 at the discharge end and the carrier plate 2100 is shown. Specifically, the portion of the comb plate 1200 at the discharge end that protrudes from the bottom of the supporting main frame 1100 at least partially overlaps with the carrier plate 2100 along the lateral direction of the lasagna rack 1000.

[0069] Based on the above technical solution, when the lifting assembly 2200 drives the carrier plate 2100 to rise and perform the loading action, the bottom of the comb plate 1200 at the feeding end is misaligned with the carrier plate 2100, so that the comb plate 1200 at the feeding end remains in the first state. At this time, the notch of the slide 1131 at the feeding end remains in a blocked and closed state, and the material tray 5000 cannot slide out from the feeding end of the lasagna rack 1000. The bottom of the comb plate 1200 at the discharging end will first contact the carrier plate 2100, and the carrier plate 2100 drives the comb plate 1200 at the discharging end to move upward and switch from the first state to the second state, and then drives the main support frame 1100 to move upward. At this time, the notch of the slide 1131 at the discharging end is in an open state, so that the material tray 5000 can slide out from the discharging end.

[0070] That is to say, the loading device of the embodiment of the present application avoids the comb plate 1200 at the feed end through the carrier plate 2100 and lifts the comb plate 1200 at the discharge end, so that the notches of all the slide slots 1131 at the feed end remain in a closed state, and the notches of all the slide slots 1131 at the discharge end are switched to an open state; during the rising process of the Thousand Layer Rack 1000, it can effectively prevent the material tray 5000 from sliding out of the feed end, thereby ensuring the stability and safety of the upward movement and loading process of the Thousand Layer Rack 1000; at the same time, through the lifting of the carrier plate 2100, the notches of the slide slots 1131 at the discharge end can be automatically opened, thereby avoiding the complexity of human intervention in opening or closing the notches of the slide slots 1131, greatly saving the labor intensity of the operators, and also facilitating the automatic removal of the PCB boards in the Thousand Layer Rack 1000, thereby improving production efficiency.

[0071] It can be understood that when loading materials, among the multiple trays 5000 stacked vertically, after the tray 5000 on the top layer is dragged out at the material picking position and the PCB board is removed, the lifting component 2200 can drive the kielder rack 1000 to move upward as a whole, so that the tray 5000 on the second top layer rises to the material picking position and is dragged out to remove the PCB board. By driving the kielder rack 1000 to move upward intermittently through the lifting mechanism 2000, all PCB boards in the kielder rack 1000 can be removed.

[0072] In the optional embodiments of this application, see Figure 5 and Figure 6, the comb plate 1200 is also movably arranged on the outside of the supporting main frame 1100 along the second transverse direction, and the first transverse direction, the second transverse direction and the longitudinal direction are perpendicular to each other. Exemplarily, the first transverse direction can be the X-axis direction, the second transverse direction can be the Y-axis direction, and the longitudinal direction can be the Z-axis direction. When the comb plate 1200 switches from the first state to the second state, the comb plate 1200 moves along the second transverse direction away from the slide groove 1131. In this way, the comb teeth 1210 can not only be displaced in the longitudinal direction to avoid the notch of the slide groove 1131, but also be displaced in the second transverse direction to avoid the notch of the slide groove 1131, so that it can be ensured that the comb teeth 1210 can stably avoid the notch of the slide groove 1131.

[0073] In a preferred embodiment of the present application, during the process of the comb plate 1200 switching from the first state to the second state, the displacement of the comb teeth 1210 in the second lateral direction is greater than the tooth depth of the comb teeth 1210. In this way, after switching to the second state, the comb teeth 1210 can be completely hidden relative to the slot, further preventing the material tray 5000 from colliding with the comb teeth 1210 during the sliding out process.

[0074] Please continue to see Figure 5 , Figure 6 , Figure 7 and Figure 8 , one of the supporting main frame 1100 and the comb plate 1200 is provided with a guide member 1121, and the other is provided with a guide groove 1220. Exemplarily, the guide member 1121 is protrudingly provided on the supporting main frame 1100, and the guide groove 1220 is provided on the comb plate 1200. The guide groove 1220 is extended in both the longitudinal direction and the second transverse direction. The comb plate 1200 is a plate-like structure, which has the characteristic of convenient processing when processing and forming the guide groove 1220. The guide member 1121 is slidably matched in the guide groove 1220 to switch the comb plate 1200 between the first state and the second state. Through the provision of the guide member 1121 and the guide groove 1220, the comb plate 1200 can have a certain motion trajectory during the lifting process, that is, it moves in both the longitudinal direction and the second transverse direction, so that the comb teeth 1210 of the comb plate 1200 can stably avoid or block the notch of the slide groove 1131.

[0075] It should be noted that, under the action of gravity, the comb plate 1200 is usually in the first state, and the guide member 1121 is in contact with the inner wall above the guide groove 1220, that is, the guide member 1121 can suspend the comb plate 1200. After the comb plate 1200 is switched from the first state to the second state, in order to keep the comb plate 1200 in the second state, the main support frame 1100 is rotatably provided with a hanging member 1140 at both the feeding end and the discharging end. The hanging member 1140 is arranged above the comb plate 1200, and a positioning member 1230 is arranged on the comb plate 1200. In the second state, the positioning member 1230 on the comb plate 1200 can be hung on the hanging member 1140, so as to maintain the comb plate 1200 in the second state. Exemplarily, the hanging member 1140 may be a hook disposed on the supporting main frame 1100 , and the hanging member 1140 has a hanging opening, and the positioning member 1230 may be hung in the hanging member 1140 through the hanging opening.

[0076] In a further technical solution, in the first state, see Figure 5 and Figure 6 , Figure 6 The relative position relationship between the comb plate 1200 and the hanging part 1140 at the feed end is shown. The positioning part 1230 of the comb plate 1200 at the feed end is located on the back side of the hanging part 1140. When the comb plate 1200 at the feed end switches from the first state to the second state, the positioning part 1230 abuts against the back side of the hanging part 1140 and causes the hanging part 1140 to rotate clockwise. At this time, the hanging part 1140 rotates to avoid the positioning part 1230 and the positioning part 1230 cannot be hung on the hanging part 1140. If it is necessary to switch the comb plate 1200 at the feed end to the second state, the hanging part 1140 can be manually hung on the positioning part 1230.

[0077] In a further technical solution, in the first state, see Figure 7 and Figure 8 , Figure 8 The relative position relationship between the comb plate 1200 at the discharging end and the hanging member 1140 is shown. The positioning member 1230 of the comb plate 1200 at the discharging end is located at the front side of the hanging member 1140. When the comb plate 1200 at the discharging end switches from the first state to the second state, the positioning member 1230 abuts against the front side of the hanging member 1140 and causes the hanging member 1140 to rotate counterclockwise. At this time, the positioning member 1230 can gradually slide through the hanging opening and be hung in the hanging member 1140. That is to say, the comb plate 1200 at the discharging end can be automatically suspended on the hanging member 1140 when switching to the second state.

[0078] It should be noted that the hanging member 1140 is rotatably arranged on the supporting main frame 1100, and the hanging member 1140 has a center of gravity position. The positioning member 1230 referred to in the embodiment of the present application is located on the back side of the hanging member 1140, which means that the positioning member 1230 is offset from the center of gravity position of the hanging member 1140, and is located on the side of the hanging member 1140 facing away from the hanging opening; the positioning member 1230 referred to in the embodiment of the present application is located on the front side of the hanging member 1140, which means that the positioning member 1230 is offset from the center of gravity position of the hanging member 1140, and is located on the side facing the hanging opening of the hanging member 1140.

[0079] Based on the above technical solution, when the operator lifts the comb plate 1200 at the feed end to observe the loading situation of the PCB board in the lasagna rack 1000, the comb plate 1200 at the feed end cannot be automatically hung on the hanging piece 1140. After the observation is completed, the comb plate 1200 at the feed end will slide downward due to gravity and switch to the first state, thereby playing an anti-mistake effect; and when the lifting mechanism 2000 lifts the comb plate 1200 at the discharge end, the comb plate 1200 at the discharge end can be lifted and stably hung on the hanging piece 1140, thereby ensuring the stability of the comb plate 1200 in the second state, and it is not easy to shake and interfere with the normal sliding of the material tray 5000 in the slot of the slide groove 1131.

[0080] For further technical solutions, see Figure 5 , Fig.13 , Fig.15 and Fig.16 The part of the comb plate 1200 protruding from the bottom surface of the supporting main frame 1100 is bent away from the supporting main frame 1100 to form a bending portion 1250. Through the setting of the bending portion 1250, when the comb plate 1200 contacts the carrier plate 2100, the bending portion 1250 can increase the abutting contact area of ​​the comb plate 1200, thereby ensuring the stability of the comb plate 1200 being lifted.

[0081] In the examples of this application, see Fig. 9 and Fig.15 A positioning pin 2110 is provided on the carrier 2100, and a second positioning hole 1112 is provided at the bottom of the supporting main frame 1100. After the supporting main frame 1100 is carried on the carrier 2100, the positioning pin 2110 is positioned and matched with the second positioning hole 1112. In this way, the stability of the carrier 2100 in carrying the Thousand Layer Frame 1000 can be improved through the positioning function of the positioning pin 2110 and the second positioning hole 1112.

[0082] In the examples of this application, see Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13The supporting main frame 1100 includes a base 1110, a longitudinal beam 1120 and a cross beam 1130, wherein a plurality of longitudinal beams 1120 are arranged on the base 1110, and a plurality of cross beams 1130 are distributed along the longitudinal direction and arranged on the longitudinal beam 1120. Exemplarily, the lower ends of the plurality of longitudinal beams 1120 can be welded and fixed to the base, and the cross beam 1130 can be welded and fixed to the longitudinal beam 1120. Specifically, the plurality of longitudinal beams 1120 are arranged on the base 1110 at intervals along the first transverse direction, and the longitudinal beam 1120 is provided with notches 1122 distributed along the longitudinal direction, the cross beam 1130 is embedded in the notch 1122, and can be connected and fixed to the longitudinal beam 1120 by welding, and the slide groove 1131 is arranged on the inner side of the cross beam 1130.

[0083] In the preferred embodiment of this application, see Fig.12 The longitudinal beam 1120 is formed by cutting a pipe to form a notch 1122. For example, the longitudinal beam 1120 can be cut from a square tube to form the notch 1122. On the one hand, the longitudinal beam 1120 made of the tube has a certain stability and can effectively prevent the longitudinal beam 1120 from deformation, thereby ensuring the structural stability of the supporting main frame 1100. On the other hand, the longitudinal beam 1120 is formed by cutting a pipe to form the notch 1122, which is easy to process, has low material cost and processing cost, and has a high cost performance.

[0084] In the preferred embodiment of this application, please continue to refer to Fig. 9 and Fig.12 The cross beam 1130 can be made of a plate, and the plate is punched to form a chute 1131. After the cross beam 1130 is punched, the cross beam 1130 as a whole forms a U-shaped trough-shaped component. When the longitudinal beam 1120 and the cross beam 1130 are connected and fixed, the opening of the cross beam 1130 is inward and embedded in the notch 1122 of the longitudinal beam 1120, and the connection and fixation of the two can be achieved by welding. In other words, by setting the notch 1122 on the longitudinal beam 1120 to form the installation position of the cross beam 1130, the assembly accuracy of the longitudinal beam 1120 and the cross beam 1130 can be improved, thereby ensuring the consistency of the extension direction of the multiple chute 1131, avoiding the relative inclination of the multiple chute 1131 existing in the direct welding connection between the longitudinal beam 1120 and the cross beam 1130, which is conducive to the automatic removal of the material tray 5000 in the multiple chute 1131.

[0085] For further technical solutions, see Fig. 9 , Fig.10 and Fig.12A longitudinal beam 1120 supporting the main frame 1100 adjacent to the discharge end is provided with a limiting protrusion 1123 protruding from the slide groove 1131, and a limiting portion is provided on the material tray 5000. For example, the limiting portion can be a columnar structure protruding downward, and along a first direction, the limiting portion and the limiting protrusion 1123 are limitedly matched, and the first direction is the direction from the feed end to the discharge end; under such a setting, in the process of the material tray 5000 sliding out of the slide groove 1131, the limiting protrusion 1123 and the limiting portion are limitedly matched to prevent the material tray 5000 from completely separating from the slide groove 1131 and causing the material tray 5000 to tilt or even fall, thereby ensuring the safety of production while preventing the PCB board from falling.

[0086] In the examples of this application, see Figure 7 , Figure 8 and Fig.13 , a gap 1240 is formed between two adjacent comb teeth 1210, the width of the slide groove 1131 is greater than the width of the comb teeth 1210, and the width of the slide groove 1131 is less than the width of the gap 1240. In this way, in the first state, it can ensure that the comb teeth 1210 can have a shielding effect on the slide groove 1131, and can effectively prevent the material tray 5000 from sliding out of the slide groove 1131. At the same time, in the second state, the notch of the slide groove 1131 can be completely located in the opening area of ​​the gap 1240, thereby ensuring the smoothness of the sliding of the material tray 5000 and avoiding the collision of the material tray 5000 with the comb teeth 1210.

[0087] In the embodiment of the present application, the lifting mechanism 2000 may be a ball screw transmission mechanism. Figure 2 and Fig.14 The lifting assembly 2200 includes a motor, a reducer 2220, a first transmission shaft 2230, a diverter 2240, a second transmission shaft 2250, a guide shaft 2260 and a ball nut 2270. The motor is connected to the reducer 2220, and the two first transmission shafts 2230 are connected to the output end of the reducer 2220. The motor can drive the two first transmission shafts 2230 to rotate synchronously. The two first transmission shafts 2230 are connected to the second transmission shaft 2250 through the diverter 2240. The second transmission shaft 2250 is arranged longitudinally and can be a screw rod. The ball nut 2270 is sleeved on the second transmission shaft 2250. The carrier 2100 is connected and fixed to the ball nut 2270 through a bracket, and the bracket is slidably matched on the longitudinally arranged guide shaft 2260. When the motor is working, the ball nut 2270 can be moved along the second transmission shaft 2250 , thereby driving the carrier plate 2100 to lift the lasagna rack 1000 .

[0088] In the embodiment of the present application, two second transmission shafts 2250 are distributed on both sides of the lasagna rack 1000, and the number of guide shafts 2260 is four. The four guide shafts 2260 are relatively arranged on both sides of the lasagna rack 1000, so that the carrier plate 2100 can be lifted to enhance the stability of the lasagna rack 1000.

[0089] See also Figure 17~Figure 19 The loading device of the embodiment of the present application may also include a trolley 3000, which can push the lasagna rack 1000 to the top of the lifting mechanism 2000, so as to realize the lifting and loading of the lifting mechanism 2000, so that the PCB boards in the material tray 5000 are separated from the lasagna rack 1000 in sequence. Fig.17 The trolley 3000 includes a base 3100, a slide rail 3200 and a locking assembly 3300, wherein the slide rail 3200 and the locking assembly 3300 are both arranged on the base 3100, and a roller 1300 is arranged at the bottom of the lasagna rack 1000 to cooperate with the guide of the slide rail 3200. The lasagna rack 1000 is supported on the slide rail 3200 by the roller 1300, and the locking assembly 3300 is used to lock the lasagna rack 1000 so that the lasagna rack 1000 will not move along the slide rail 3200.

[0090] Specifically, see Fig.18 and Fig.19 The locking assembly 3300 includes a guide seat 3310 and a locking piece 3320, wherein the guide seat 3310 has a longitudinally extending guide hole 3311 and a first notch 3312 and a second notch 3313 connected to the guide hole 3311, the first notch 3312 and the second notch 3313 are distributed along the height direction of the guide seat 3310, and the first notch 3312 and the second notch 3313 are distributed at different circumferential positions of the guide seat 3310, and the first notch 3312 is located above the second notch 3313.

[0091] The locking member 3320 includes a shaft rod 3321 and a blocking rod 3322 connected to the shaft rod 3321. The shaft rod 3321 is inserted into the guide hole 3311. The locking member 3320 has a locked state and an unlocked state. In the locked state, the blocking rod 3322 is located in the first notch 3312. In the unlocked state, the blocking rod 3322 is located in the second notch 3313.

[0092] See also Fig. 9 , Fig.18 and Fig.19A first positioning hole 1111 is provided at the bottom of the lasagna rack 1000. In the unlocked state, since the shaft rod 3321 is lower at this time, the upper end of the shaft rod 3321 is separated from the first positioning hole 1111. In the locked state, the upper end of the shaft rod 3321 is inserted into the first positioning hole 1111. When switching the locking member 3320 from the unlocked state to the locked state, the shaft rod 3321 can be lifted first, and then the locking member 3320 can be rotated so that the blocking rod 3322 is located in the first notch 3312, thereby switching the locking member 3320 to the locked state.

[0093] In the examples of this application, see Figure 3 , Fig. 20 and Fig.21 The clamping mechanism 6000 includes a bracket 6100 and a clamping unit 6200, wherein the clamping unit 6200 as the main functional component of the clamping mechanism 6000 can realize the clamping action, the bracket 6100 can provide an installation basis for the clamping unit 6200, the clamping unit 6200 is arranged on the bracket 6100, and the bracket 6100 is connected to the driving mechanism 7000. The clamping unit 6200 includes a cylinder 6210, an upper clamping jaw 6220 and a lower clamping jaw 6230, and a clamping opening 6240 is formed between the upper clamping jaw 6220 and the lower clamping jaw 6230. When the driving mechanism 7000 drives the clamping mechanism 6000 to move, the material tray 5000 can be inserted into the clamping opening 6240 toward the side of the clamping mechanism 6000, and the cylinder 6210 is connected to the lower clamping jaw 6230 to drive the lower clamping jaw 6230 to move, so that the clamping unit 6200 is switched between the clamping state and the release state. Illustratively, when the cylinder 6210 drives the lower clamp 6230 away from the upper clamp 6220, the clamping unit 6200 switches to a released state, at which time the opening width of the clamping opening 6240 is larger, making it easy for the material tray 5000 to enter the clamping opening 6240; and when the cylinder 6210 drives the lower clamp 6230 close to the upper clamp 6220, the clamping unit 6200 switches to a clamping state, at which time the opening width of the clamping opening 6240 is smaller, making it difficult for the part of the material tray 5000 located in the clamping opening 6240 to detach.

[0094] In a further technical solution, in order to ensure the stability of the clamping unit 6200 clamping the material tray 5000, please refer to Fig.21 and Fig.23A receiving groove 6231 is provided on the lower clamping jaw 6230, and the notch of the receiving groove 6231 faces upward. The receiving groove 6231 includes a first transverse section 6231a and a second transverse section 6231b connected to the first transverse section 6231a, wherein the groove width of the first transverse section 6231a is greater than the width of the first cross bar 5100, and the first transverse section 6231a is used to receive part of the first cross bar 5100, and the groove width of the second transverse section 6231b is greater than the width of the second cross bar 5200, and the second transverse section 6231b is used to receive part of the second cross bar 5200 at the edge of the material tray 5000. When the clamping unit 6200 clamps the material tray 5000, the first cross section 6231a and the second cross section 6231b form a limiting effect on the first cross bar 5100 and the second cross bar 5200, so that the edge portion of the material tray 5000 can be clamped on the clamping unit 6200 more stably during the clamping process, which helps to reduce shaking or falling off during the process of dragging the material tray 5000, thereby improving the stability and safety of dragging the material tray 5000.

[0095] In the embodiment of the present application, the cylinder 6210 drives the lower clamping jaw 6230 to move so as to realize the switching of the clamping unit 6200 between the clamping state and the release state. When the clamping unit 6200 switches from the release state to the clamping state, the lower clamping jaw 6230 moves upward to support the edge of the tray 5000. Along the conveying direction of the conveying mechanism 4000, the upper clamping jaw 6220 and the lower clamping jaw 6230 are staggered, and the two upper clamping jaws 6220 are distributed on both sides of the lower clamping jaw 6230. In this way, on the one hand, the upper clamping jaw 6220 can avoid the connection layout of the cylinder 6210 and the lower clamping jaw 6230. On the other hand, the two upper clamping jaws 6220 are distributed on both sides of the lower clamping jaw 6230 to avoid the tray 5000 from tilting, thereby improving the stability of the clamping unit 6200 in clamping the tray 5000.

[0096] In the examples of this application, please continue to refer to Fig.23 and Fig.24 A first guide surface 6221 is provided at the front end of the upper clamping jaw 6220, and a second guide surface 6232 is provided at the front end of the lower clamping jaw 6230. The first guide surface 6221 and the second guide surface 6232 are arranged opposite to each other, and the first guide surface 6221 and the second guide surface 6232 are both inclined relative to the moving direction of the clamping mechanism 6000, so that the front end of the clamping opening 6240 is in a contracted shape. In this way, in the process of the material tray 5000 probing into the clamping opening 6240, the collision between the clamping unit 6200 and the material tray 5000 can be avoided, ensuring that the edge of the material tray 5000 can enter the clamping opening 6240 and slide into the accommodating groove 6231 under the guidance of the first guide surface 6221 and the second guide surface 6232.

[0097] In a further technical solution, along the moving direction of the clamping mechanism 6000, the front end of the lower clamping jaw 6230 protrudes from the front end of the upper clamping jaw 6220, and the front end of the upper clamping jaw 6220 is located in the area of ​​the second guide surface 6232. With such a configuration, on the one hand, because the PCB board is placed on the upper surface of the tray 5000, when the clamping unit 6200 moves toward the tray 5000, the lower clamping jaw 6230 first moves to the area where the tray 5000 is located, and even if the lower clamping jaw 6230 slightly collides with the tray 5000, the upper clamping jaw 6220 will not cause scratches to the PCB board placed on the upper surface of the tray 5000.

[0098] From the above, we can see that Figure 3 , Fig. 20 and Fig.21 , the driving mechanism 7000 can drive the clamping mechanism 6000 to move toward the material tray 5000 to clamp the material tray 5000. In the embodiment of the present application, there is a gap area 4200 between the multiple conveying roller groups 4100 for the bracket 6100 to pass through. The bracket 6100 has a longitudinally extending plate-like structure. The lower end of the plate-like structure is located below the conveying roller group 4100 and is connected to the driving mechanism 7000. The plate-like structure passes through the gap area 4200 and extends to the top of the conveying roller group 4100. The clamping mechanism 6000 is connected to the top of the plate-like structure. In this arrangement, by setting the gap area 4200 between the multiple conveying roller groups 4100 for the plate-like structure to pass through, the layout mode of the driving mechanism 7000 at the bottom and the clamping mechanism 6000 at the top can be realized, which improves the compactness of the entire material-taking device structure. In addition, this layout mode can also realize that the conveying roller group 4100 lifts and contacts the PCB board and conveys the PCB board, which can reduce unnecessary friction and scratches on the PCB board and improve the safety of PCB board transportation.

[0099] For further technical solutions, please continue to refer to Fig.21The plate-like structure is provided with an avoidance recess 6110 at a position corresponding to the conveying roller set 4100 . When the driving mechanism 7000 drives the clamping mechanism 6000 to move, the avoidance recess 6110 can avoid the conveying roller set 4100 . By providing an avoidance recess 6110 on the plate-like structure of the bracket 6100, on the one hand, the bracket 6100 can drive the clamping mechanism 6000 to pass through the conveying roller group 4100 to clamp the material tray 5000; on the other hand, the avoidance recess 6110 can make the distance between two adjacent conveying roller groups 4100 smaller, that is, the width of the gap area 4200 is smaller, and a high-density contact between the multiple conveying roller groups 4100 and the PCB board can be achieved, thereby preventing the PCB board from shaking and deviating from the predetermined path and colliding and scratching with the edge of the conveying mechanism 4000; at the same time, the movement of the PCB board on the conveying roller group 4100 mainly depends on the friction between the PCB board and the roller 4120. By providing the avoidance recess 6110 to reduce the width of the gap area 4200, it can be ensured that the multiple conveying roller groups 4100 provide sufficient friction to the PCB board, thereby maintaining the continuous movement of the PCB board.

[0100] In the optional embodiments of this application, see Fig.21 and Fig. 22 The clamping mechanism 6000 may further include a detection module 6300, which includes an upper mounting member 6310, a lower mounting member 6320 and a detection sensor 6330. The upper mounting member 6310 and the lower mounting member 6320 are both connected and fixed to the bracket 6100. The upper mounting member 6310 and the lower mounting member 6320 are opposite to each other and are spaced apart to form an avoidance opening 6340 therebetween. When the clamping unit 6200 clamps the material tray 5000, the edge of the material tray 5000 can be inserted into the avoidance opening 6340.

[0101] Please continue to see Fig. 22 , the upper mounting member 6310 and the lower mounting member 6320 are both provided with a receiving cavity 6311 and a side opening communicating with the receiving cavity 6311, and the detection sensor 6330 can be assembled into the receiving cavity 6311 through the side opening, and the convenience of assembling the detection sensor 6330 can be improved through the side opening. Exemplarily, the upper mounting member 6310 and the lower mounting member 6320 can be structural members made of plastic materials, the first cross bar 5100 and the second cross bar 5200 of the material tray 5000 can be metal components, and the detection sensor 6330 can be an inductive sensor. When the detection sensors 6330 in the upper mounting member 6310 and the lower mounting member 6320 detect the trigger signal at the same time, it means that the material tray 5000 has been accurately clamped by the clamping unit 6200, otherwise it means that the clamping unit 6200 has a clamping abnormality during clamping, and the staff needs to perform maintenance.

[0102] In the embodiment of the present application, the driving mechanism 7000 can be one of a gear rack transmission mechanism, a chain transmission mechanism, a ball screw transmission mechanism and a belt transmission mechanism, as long as it can achieve driving the clamping mechanism 6000 to stably pass through the conveying roller group 4100, and the embodiment of the present application does not make specific restrictions on this. Similarly, the lifting mechanism 8000 can be one of a cylinder, a hydraulic cylinder, an electric push rod and a ball screw transmission mechanism, as long as it can achieve lifting of the conveying mechanism 4000, and the embodiment of the present application does not make specific restrictions on this.
