[0057] For example, please refer to Figure 1-Figure 3 The main machine 1000 includes a main machine base frame 1100 and a main machine module 1200. The main machine module 1200 is installed on the main machine base frame 1100, wherein the incoming material module 2000 and the conveying module 4000 are both installed on the main machine base frame 1100. The main machine module 1200 includes a transverse movement module 1210 and an electric control module 1220. The material picking module 3000 is installed on the output end of the transverse movement module 1210. The transverse movement module 1210 can drive the material picking module 3000 to move horizontally. The electric control module 1220 is communicatively connected with the transverse movement module 1210, the incoming material module 2000, the material picking module 3000 and the conveying module 4000.

[0058] Exemplarily, the incoming material module 2000 is installed on the main frame 1100 in a modular form, that is, the incoming material module 2000 and the main frame 1100 can be detachably connected in terms of mechanical structure and electrical structure. The user can install different types of incoming material modules 2000 on the main frame 1100 as needed to achieve rapid equipment adjustment and improve the flexibility of the plate loading equipment.

[0059] For details, please refer to Figure 3-Figure 5 One of the main frame 1100 and the incoming material module 2000 is provided with a guide member 11, and the other is provided with a guide track 12. The guide member 11 can slide or roll along the guide track 12, so that the incoming material module 2000 moves toward or away from the installation position on the main frame 1100 along the guide track 12. In this embodiment, please refer to Figure 1-Figure 10, a guide rail 12 is arranged on the main frame 1100, and a guide member 11 is arranged on the incoming material module 2000, and the guide member 11 is specifically a plurality of rollers. A U-shaped opening is arranged on the side of the main frame 1100 to accommodate the incoming material module 2000, and both sides of the U-shaped opening are provided with guide rails 12 extending along the depth direction thereof, and the depth direction of the U-shaped opening is the second direction (i.e., the Y direction in the figure). A running wheel 2130 is arranged at the bottom of the incoming material module 2000, and the incoming material module 2000 can be moved on the ground. Guide members 11 are arranged on both sides of the left and right sides of the incoming material module 2000, and the incoming material module 2000 is moved toward the U-shaped opening, and the guide members 11 on both sides thereof roll on the corresponding guide rails 12 respectively, until the incoming material module 2000 moves to the installation position where the incoming material module 2000 is docked with the main frame 1100. When it is necessary to detach the incoming material module 2000, the incoming material module 2000 can be gradually separated from the U-shaped opening by dragging it in the opposite direction.

[0060] For example, please refer to Figure 3-Figure 5 , one of the main frame 1100 and the incoming material module 2000 is provided with a first positioning portion 13, and the other is provided with a second positioning portion 14. When the incoming material module 2000 moves to the installation position where it is docked with the main frame 1100, the first positioning portion 13 and the second positioning portion 14 are structurally connected to completely fix the incoming material module 2000 with the main frame 1100. In this embodiment, the first positioning portion 13 is provided on the main frame 1100, and the second positioning portion 14 is provided on the incoming material module 2000. The first positioning portion 13 and the second positioning portion 14 are both provided with positioning hole structures. When the incoming material module 2000 moves to the installation position where it is docked with the main frame 1100, the two groups of positioning holes are coaxially arranged and interconnected. The staff inserts the positioning pins into the first positioning portion 13 and the second positioning portion 14 at the same time to fix the incoming material module 2000 to the main frame 1100, and the disassembly and assembly are very convenient. In some embodiments, the first positioning portion 13 may be configured as a positioning pin, and the second positioning portion 14 may be configured as a positioning hole. The positioning pin may be directly inserted into the positioning hole to fix the feed module 2000 to the host chassis 1100 .

[0061] For example, please refer to Figure 3-Figure 5 , one of the main frame 1100 and the incoming material module 2000 is provided with an electrical socket (not shown in the figure), and the other is provided with an electrical plug 15. When the incoming material module 2000 moves to the installation position where it is docked with the main frame 1100, the electrical plug 15 is also plugged into the electrical socket to electrically connect the incoming material module 2000 with the main station 1000. Specifically, the main frame 1100 is provided with an electrical socket, and the electrical socket is connected to the electric control module 1220 through a cable. The incoming material module 2000 is provided with an electrical plug 15. When the electrical plug 15 is plugged into the electrical socket, the electric control module 1220 is electrically connected to the incoming material module 2000.

[0062] Exemplarily, the material picking module 3000 is installed at the output end of the transverse movement module 1210 in a modular form, that is, the material picking module 3000 is detachably connected to the transverse movement module 1210 in terms of mechanical structure, and is detachably connected to the electric control module 1220 in terms of electrical structure. Users can install different types of material picking modules 3000 on the transverse movement module 1210 as needed to achieve rapid equipment adjustment and improve the flexibility of the plate loading equipment. Specifically, the material picking module 3000 can be detachably connected to the output end of the transverse movement module 1210 by fastening bolts, and an electrical socket is provided on the material picking module 3000, which is electrically connected to the electric control module 1220 through a pluggable electrical connection cable.

[0063] For example, the lateral movement module 1210 may adopt a gantry structure or a cantilever structure, which may be configured according to the use requirements and working conditions. Figure 2-Figure 3 The transverse movement module 1210 of this embodiment adopts a gantry structure, and the transverse movement module 1210 includes a fixed seat 1211, a first transverse movement driving assembly 1212, a first slide rail 1213, a second slide rail 1214, a sliding beam 1215 and a second transverse movement driving assembly 1216, wherein two fixed seats 1211 spaced apart along the X direction are fixed on the main frame 1100, and the fixed seat 1211 extends along the Y direction, and the two ends of the sliding beam 1215 are respectively connected to the two fixed seats 1211 in a sliding manner along the Y direction, and the upper surface of the fixed seat 1211 is provided with a first slide rail 1213, and the fixed seat 1 A second slide rail 1214 is provided on the side wall facing inwardly of 211, and the end of the sliding beam 1215 is slidably connected to the first slide rail 1213 and the second slide rail 1214 through the sliding plate portion, which greatly improves the sliding connection reliability and sliding control accuracy. The first transverse driving component 1212 is installed on the sliding plate portion, and its output end is connected to the fixed seat 1211 to drive the sliding beam 1215 to slide along the Y direction. The second transverse driving component 1216 is installed on the sliding beam 1215, and its output end is connected to the material picking module 3000 to drive the material picking module 3000 to slide relative to the sliding beam 1215 along the X direction. Specifically, the first transverse driving component 1212 can select a power component composed of a rotating motor and a transmission structure such as a synchronous pulley and a gear rack, and the second transverse driving component 1216 can select a horizontally arranged linear slide structure. Its specific structure and working principle are all existing technologies and will not be repeated here.

[0064] For example, please refer to Figure 2-Figure 3The main frame 1100 has an upper table and a lower table. The conveying module 4000 includes a forward conveying mechanism 4100 and a reflux conveying mechanism 4200. The forward conveying mechanism 4100 is arranged on the upper layer of the main frame 1100. The forward conveying mechanism 4100 is used to convey the fixture that carries the plate material loaded by the material taking module 3000, and the reflux conveying mechanism 4200 is arranged on the lower layer of the main frame 1100. The reflux conveying mechanism 4200 is used to convey the unloaded fixture. The conveying direction of the reflux conveying mechanism 4200 is opposite to the conveying direction of the forward conveying mechanism 4100. The conveying direction of the forward conveying mechanism 4100 is the same as the X direction, and the conveying direction of the reflux conveying mechanism 4200 is opposite to the X direction. The plate feeding equipment can cooperate with the conveying lines and fixture lifting equipment on other equipment in the automated production line to automatically circulate the fixtures, thereby further improving the degree of automation. Specifically, both the forward conveying mechanism 4100 and the return conveying mechanism 4200 may adopt a single-track or double-track conveying line structure in the prior art, and the specific structure thereof will not be described in detail herein.

[0065] For example, please refer to Figure 1 The main platform 1000 also includes a hood 1230 and a lifting door 1240. The hood 1230 is installed above the main frame 1100 and is arranged outside the transverse movement module 1210 and the electric control module 1220. The lifting door 1240 is slidably arranged on the side of the hood 1230 along the vertical direction to selectively open the side opening of the hood 1230. The lifting door 1240 is provided with an interactive panel and / or control buttons electrically connected to the electric control module 1220 for the operator to control the plate feeding equipment. Specifically, in order to perform maintenance and replacement of the equipment, a door that is frequently opened and closed will be provided on the machine hood 1230. Traditional machine doors are generally double-doors or flip-type doors, but these two types of doors will occupy the side space of the equipment when opened, causing the equipment to occupy a large production space, which is prone to bumps and collisions, posing a safety hazard. The lifting door 1240 of the present application can automatically move up or down in the vertical direction to avoid occupying the side space of the equipment, thereby reducing the production space occupied by the equipment, avoiding bumps and collisions, and being safer. It can be understood that the lifting door 1240 can be composed of a fixed frame, a lifting door body, a lifting component and a driving mechanism. The lifting component is composed of a driving wheel, a first guide wheel, a second guide wheel and a transmission member. The upper and lower ends of the transmission member are respectively connected to the upper and lower ends of the lifting door body, and the transmission member is sequentially connected around the first guide wheel, the driving wheel and the second guide wheel. The driving mechanism is used to drive the driving wheel to rotate, so that the driving wheel drives the transmission member to move. When the driving wheel rotates forward, the upper and lower ends of the transmission member move upward synchronously, thereby driving the lifting door body to move upward. When the driving wheel rotates reversely, the upper and lower ends of the transmission member move downward synchronously, thereby driving the lifting door body to move downward.

[0066] For example, please refer to Figure 1-Figure 2Upper avoidance openings 1231 are provided on opposite sides of the hood 1230 for the jigs transported by the forward conveying mechanism 4100 to pass in or out; lower avoidance openings 1101 are provided on opposite sides of the main frame 1100 for the jigs transported by the reflux conveying mechanism 4200 to pass in or out.

[0067] For example, at least two loading stations are provided on the main machine 1000, and each loading station is provided with a corresponding incoming material module 2000 and a retrieving material module 3000, so as to realize simultaneous loading of multiple stations and improve loading efficiency. Figure 1-Figure 3 Two loading stations are symmetrically arranged at both ends of the main platform 1000 in the Y direction. U-shaped openings are provided on the opposite sides of the main frame 1100 for the incoming material module 2000 to be loaded. The first transverse driving assembly 1212, the sliding beam 1215 and the second transverse driving assembly 1216 in the transverse module 1210 are also correspondingly arranged in two groups. The conveying module 4000 is also symmetrically arranged in two groups. The two lifting doors 1240 are respectively arranged corresponding to the two loading stations, which is convenient for the staff to observe and debug the equipment.

[0068] Exemplarily, the incoming material module 2000 is used to convey the carrier 2010 and cooperate with the picking module 3000. After the picking module 3000 takes out all the plates from the carrier 2010, the empty carrier 2010 is recovered and replenished with a new fully loaded carrier 2010, thereby achieving the purpose of automatically replacing the carrier 2010.

[0069] Please refer to Figure 4-Figure 5 The incoming material module 2000 includes a loading rack 2100, a transverse conveying device 2200 and a lifting conveying device. Among them, the loading rack 2100 has an upper platform 2110 and a lower frame 2120, the upper platform 2110 is provided with a recycling station 2001 and two material picking stations 2002, the two material picking stations 2002 are respectively arranged on both sides of the recycling station 2001, and one side of the lower frame 2120 is provided with an avoidance opening for the carrier 2010 to enter and exit; the transverse conveying device 2200 is arranged on the upper platform 2110, and the transverse conveying device 2200 is used to drive the carrier 2010 to move from the material picking station 2002 to the recycling station 2001; the lifting and conveying device is arranged on the lower frame 2120, and the lifting and conveying device is used to drive the carrier 2010 to be loaded to move from the avoidance opening into the lower frame 2120 and rise to the material picking station 2002, and to drive the carrier 2010 on the recycling station 2001 to descend and move out of the lower frame 2120 from the avoidance opening.

[0070] Specifically, the two material taking stations 2002 allow the loading device to take materials from the two trays 2010 alternately or simultaneously. After the tray 2010 is empty, the transverse conveyor 2200 drives the tray 2010 to move from the material taking station 2002 to the recycling station 2001. At the same time, in the lower frame 2120 of the loading rack 2100, the lifting conveyor drives the tray 2010 to be loaded to move in and rise to the recycling station 2001. The lifting conveyor also drives the tray 2010 at the recycling station 2001 to descend and move out from the lower frame 2120. The incoming material module 2000 realizes the fully automatic replacement of the tray 2010, with a higher degree of automation. In addition, by setting up the double material taking stations 2002, the loading action and the recycling action of the tray 2010 will not interrupt each other, so that continuous loading operation is realized and production efficiency is improved.

[0071] For example, please refer to Figure 4-Figure 5 The two material-retrieving stations 2002 are both provided with a chuck device 2300, which is used to clamp and fix the carrier 2010 to improve the stability during material loading. Furthermore, the output end of the transverse conveyor 2200 is connected to the chuck device 2300 to drive the chuck device 2300 to move between the material-retrieving station 2002 and the recycling station 2001. When the transverse conveyor 2200 is in motion, the chuck device 2300 fixes the carrier 2010 to ensure the stability of horizontal transmission and improve reliability.

[0072] For example, please refer to Figure 4-Figure 5 , the recovery station 2001 and the material taking station 2002 are distributed along the horizontal X direction, and the output end of the transverse conveyor 2200 is also telescopically arranged along the X direction. Specifically, the transverse conveyor 2200 has two output ends respectively arranged corresponding to the two material taking stations 2002, and the two chuck devices 2300 are respectively connected to the two output ends of the transverse conveyor 2200. The transverse conveyor 2200 specifically includes two linear driving members 2210 with opposite telescopic directions. The linear driving member 2210 can be an electric push rod or a linear cylinder. In this embodiment, the linear driving member 2210 is a linear cylinder. The telescopic end of one linear cylinder is arranged in the X direction and connected to one of the chuck devices 2300, and the telescopic end of the other linear cylinder is arranged in the opposite direction of the X direction and connected to the other chuck device 2300.

[0073] For example, please refer to Figure 7The chuck device 2300 includes a square frame base 2310, two chuck drive assemblies 2320 and two clamping rods 2330. The square frame base 2310 is connected to the upper platform 2110 in a sliding manner along the X direction through a slide rail slider structure, the output end of the transverse conveyor 2200 is connected to the square frame base 2310, and a hollow portion is provided in the middle of the square frame base 2310 to allow the lifting conveyor to drive the carrier 2010 to pass through in the vertical direction; the two chuck drive assemblies 2320 are symmetrically installed on the square frame base 2310 about the Y direction, and the two clamping rods 2330 are connected to the output ends of the two chuck drive assemblies 2320 in a one-to-one correspondence. The two clamping rods 2330 are respectively provided corresponding to the two opposite first side edges 2311 on the square frame base 2310, and the two clamping rods 2330 are respectively driven by the two chuck drive assemblies 2320 to move closer to each other to clamp the carrier 2010 between them.

[0074] For further information, please refer to Figure 7 The chuck drive assembly 2320 includes two chuck drive members 2321 and two chuck connection blocks 2322. The two chuck drive members 2321 are respectively arranged on two second side edges 2312 arranged opposite to each other on the frame base 2310. The two chuck connection blocks 2322 are respectively slidably arranged on the two second side edges 2312 through the slide rail slider structure. The two chuck connection blocks 2322 are respectively connected to the output ends of the two chuck drive members 2321 and the two ends of the clamping rod 2330. Specifically, the two chuck drive members 2321 in the same chuck drive assembly 2320 are extended and retracted in the same direction. When working, the two chuck drive members 2321 are synchronously extended and retracted to drive the clamping rod 2330 to translate along the length direction of the second side edge 2312. The extension directions of the chuck drive members 2321 of different groups of chuck drive assemblies 2320 are opposite. The two groups of chuck drive assemblies 2320 cooperate to make the two clamping rods 2330 translate toward or away from each other. The chuck driving member 2321 may be an electric push rod or a linear cylinder. In the present embodiment, the chuck driving member 2321 is a linear cylinder.

[0075] For example, please refer to Figure 7 The chuck connecting block 2322 is provided with an adjustment hole 2323 extending in the same direction as the second side 2312. The chuck connecting block 2322 and the clamping rod 2330 are connected by a fastening bolt passing through the adjustment hole 2323. The relative position of the fastening bolt and the adjustment hole 2323 is adjustable so that the user can adjust the parallelism and spacing between the two clamping rods 2330 to improve flexibility.

[0076] For example, please refer to Figure 6-Figure 7A clamping groove 2011 is provided at the bottom of the side corresponding to the carrier 2010 and the clamping rod 2330, and a clamping piece 2331 is installed on the clamping rod 2330. When the clamping rod 2330 moves toward the carrier 2010, the clamping piece 2331 extends into the clamping groove 2011 and abuts against the inner wall of the clamping groove 2011, and the clamping piece 2331 can support the top wall of the clamping groove 2011.

[0077] For example, please refer to Figure 6-Figure 7 A plurality of adsorption holes 2012 are provided on the material receiving area of ​​the carrier plate 2010, and an external hole 2013 is provided on the frame area of ​​the carrier plate 2010. The plurality of adsorption holes 2012 are connected to the external holes 2013 through an air passage. The incoming material module 2000 also includes a vacuum adsorption device 2400 connected to an external vacuum generating mechanism. The vacuum adsorption device 2400 can be connected to the external hole 2013. When the vacuum generating mechanism is working, the air in the air passage is extracted through the vacuum adsorption device 2400, thereby adsorbing and fixing the protective film on the lower side of the plate, thereby preventing the protective film from being mistakenly taken by the material taking module 3000, and improving reliability.

[0078] For example, please refer to Figure 4-Figure 7 The vacuum adsorption device 2400 is installed on the chuck device 2300, and two vacuum adsorption devices 2400 are installed on each chuck device 2300. The two vacuum adsorption devices 2400 are respectively arranged on the two second side edges 2312 of the square frame base 2310, corresponding to the external connection holes 2013 arranged at both ends of the carrier 2010 in the Y direction. The vacuum adsorption device 2400 includes a lifting drive member 2410, a suction nozzle 2420 and a suction mounting plate 2430. The lifting drive member 2410 is installed on the second side edge 2312 and is located between the two chuck drive members 2321. The suction mounting plate 2430 is fixed to the output end of the lifting drive member 2410. The suction mounting plate 2430 is installed with a suction nozzle 2420. The number of the suction nozzles 2420 can be selected as one, two or more than three. In this embodiment, the suction mounting plate 2430 is installed with two suction nozzles 2420, and the suction nozzles 2420 are connected to the vacuum generating mechanism through an air pipe. Driven by the lifting drive 2410, the suction nozzle 2420 can be lifted and lowered in the vertical direction to be close to or away from the carrier 2010. When the suction nozzle 2420 is lowered to a preset height, the suction nozzle 2420 is connected to the external connection hole 2013. The lifting drive 2410 can be an electric push rod or a linear cylinder. In this embodiment, the lifting drive 2410 is a linear cylinder.

[0079] For example, please refer to Figure 4A control device 2500 is also provided on the upper platform 2110. The control device 2500 is provided inside the control device 2500 and is electrically connected to the transverse conveying device 2200, the lifting conveying device, the chuck device 2300 and the vacuum adsorption device 2400. A control panel is provided on the outside of the control device 2500, and a plurality of control buttons are provided on the control panel.

[0080] For example, please refer to Figure 4 The lifting and conveying device includes three lifting and conveying mechanisms 2600 arranged side by side along the X direction. The three lifting and conveying mechanisms 2600 are respectively arranged corresponding to the recycling station 2001 and the two material taking stations 2002. The lifting and conveying mechanism 2600 includes a horizontal conveying component 2610 and a lifting platform component 2620. The horizontal conveying component 2610 is arranged at the bottom of the lower frame 2120, and is used to drive the carrier 2010 to be horizontally transferred into or out of the lower frame 2120 along the Y direction. The lifting platform component 2620 is arranged on the inner wall of the lower frame 2120 along the vertical direction, and the lifting platform component 2620 is arranged at the end of the horizontal conveying component 2610, and is used to drive the carrier 2010 to be lifted and lowered between the horizontal conveying component 2610 and the upper platform 2110. The horizontal conveying component 2610 adopts the multi-roller transmission line in the prior art, and the lifting platform component 2620 adopts the lifting slide structure in the prior art. The specific structures and working principles of the two are all prior art, which will not be repeated here.

[0081] It can be understood that the lifting and conveying mechanism 2600 set at the corresponding recycling station 2001 is used to drive the carrier 2010 on the recycling station 2001 to descend and move it out from the lower frame 2120, and the lifting and conveying mechanism 2600 set at the corresponding material picking station 2002 is used to drive the carrier 2010 to be loaded to move into the lower frame 2120 and rise to the material picking station 2002.

[0082] Specifically, below the material-retrieving station 2002, a worker puts a plurality of trays 2010 carrying workpieces into the avoidance opening, and the plurality of trays 2010 are stacked, and the horizontal conveying assembly 2610 drives the plurality of trays 2010 to move horizontally to the inner end. At this time, the lifting platform assembly 2620 drops below the supporting surface of the horizontal conveying assembly 2610, and then the lifting platform assembly 2620 rises, driving the plurality of trays 2010 to rise, so that the top tray 2010 reaches the material-retrieving station 2002, and the chuck device 2300 clamps the top tray 2010. At this time, the lifting platform assembly 2620 drives the remaining trays 2010 to descend to a certain height, so that they are separated from the tray 2010 of the chuck device 2300. After the workpieces on the tray 2010 are loaded, the transverse conveying device 2200 drives the tray 2010 to move to the recycling station 2001, which is arranged at The lifting platform assembly 2620 below the material picking station 2002 continues to push the next carrier 2010 up to the material picking station 2002 to realize the function of loading materials layer by layer. The transverse conveying device 2200 can alternately transfer the carriers 2010 on the two material picking stations 2002 to the recycling station 2001. The lifting platform assembly 2620 arranged below the recycling station 2001 receives the carrier 2010 released by the clamping device 2300. Each time a carrier 2010 is received, the lifting platform assembly 2620 descends a certain height to realize the function of recovering the carriers 2010 layer by layer. When the number of carriers 2010 to be recovered reaches a preset value, the lifting platform assembly 2620 descends to the lowest point, and the corresponding horizontal conveying assembly 2610 carries multiple carriers 2010 and drives multiple carriers 2010 to be transmitted outward from the avoidance opening, so that the staff can recover multiple carriers 2010 at the same time.

[0083] For example, please refer to Figure 4 Adjacent lifting and conveying mechanisms 2600 are separated by isolation sheet metal 2630, and three conveying cavities are formed in the lower frame 2120 to ensure that each lifting and conveying mechanism 2600 independently conveys the carrier 2010, limits the lateral position of the carrier 2010, prevents the carrier 2010 from sliding sideways, and further improves reliability. On the side close to the avoidance opening, the isolation sheet metal 2630 is provided with an avoidance slope 2631, so that the conveying cavity forms a speaker docking interface, which facilitates the entry and exit of the carrier 2010.

[0084] For example, please refer to Figure 8-Figure 10The material picking module 3000 includes a lifting and rotating mechanism 3100 and a clamping mechanism 100. The lifting and rotating mechanism 3100 is installed at the output end of the transverse movement module 1210, specifically installed at the output end of the second transverse movement drive assembly 1216. The clamping mechanism 100 is installed at the output end of the lifting and rotating mechanism 3100. The lifting and rotating mechanism 3100 is used to drive the clamping mechanism 100 to lift vertically. The clamping mechanism 100 includes two clamping jaw assemblies 120 that can move horizontally toward each other. The clamping jaw assembly 120 includes a clamping jaw plate 121 and a supporting plate 122. The clamping jaw plate 121 is used to clamp the side edge of the plate. The supporting plate 122 is movably connected to the clamping jaw plate 121. The supporting plate 122 can extend horizontally from the inner side of the clamping jaw plate 121 to support the bottom of the plate. It should be noted that the inner side of the clamping plate 121 mentioned above specifically refers to the side of the clamping plate 121 facing the clamping space, and the clamping space is the space area formed between the two clamping plates 121 and capable of accommodating a plate.

[0085] Exemplarily, the plate material may be a reinforcing rib plate. For example, in some products, reinforcing rib plates need to be installed on the upper and lower sides of the PCBA board to protect the PCBA board. The material picking module 3000 of the present application may be used to clamp the reinforcing rib plate and place it on the PCBA board to cooperate with other locking mechanisms to realize the installation of the reinforcing rib plate on the PCBA board.

[0086] Specifically, when the material picking module 3000 provided in this embodiment clamps the plate, the clamping plate 121 clamps the side edge of the plate, and the supporting plate 122 can extend horizontally from the inner side of the clamping plate 121 to support the bottom of the supporting plate 122 material, so as to achieve multi-point clamping and support of the plate. It can be seen that when clamping the plate, the plate is mainly lifted by the supporting plate 122, and the two clamping plates 121 press against the side edge of the plate to play the role of positioning the plate. The clamping of the plate does not rely on the friction force applied by the two clamping plates 121, so it can greatly reduce the pressure applied by the clamping plates 121 on the edge of the plate, avoid damaging the plate, and ensure the stability of the clamping plate feeding without increasing the clamping contact area, avoid the problem of structural interference, and is suitable for feeding operations of various plates.

[0087] Exemplarily, the lifting and rotating mechanism 3100 is composed of a lifting drive assembly (not shown in the figure) and a rotating drive assembly (not shown in the figure). The lifting drive assembly is fixed to the output end of the second transverse driving assembly 1216 through a mounting plate, the rotating drive assembly is installed at the output end of the lifting drive assembly, and the clamping mechanism 100 is installed at the output end of the rotating drive assembly. When working, the lifting drive assembly can drive the rotating drive assembly and the clamping mechanism 100 to lift together, and the rotating drive assembly can drive the clamping mechanism 100 to rotate around the vertical direction to adjust the horizontal orientation of the clamping mechanism 100. Specifically, the lifting drive assembly can adopt a linear power assembly composed of a rotating motor and a ball screw structure or directly adopt an electric push rod, and the rotating drive assembly can adopt a rotating power part such as a reduction motor. Both are prior arts, and their specific structures and working principles are not repeated here.

[0088] For example, please refer to Figure 8-Figure 10 The material clamping mechanism 100 further includes a material clamping frame 110 and an opening and closing driving assembly 130. Two clamping jaw assemblies 120 are respectively slidably arranged on the material clamping frame 110 through a clamping jaw mounting plate 128. The opening and closing driving assembly 130 includes a rotary driving member 131 and a first screw segment 132 and a second screw segment 133 which are transmission-connected thereto. The first screw segment 132 is connected to one clamping jaw assembly 120 through a screw nut, and the second screw segment 133 is connected to the other clamping jaw assembly 120 through another screw nut. The thread direction of the first screw segment 132 is opposite to that of the second screw segment 133. When the rotary driving member 131 rotates in the positive direction, the two clamping jaw assemblies 120 move closer to each other to clamp the plate therebetween; when the rotary driving member 131 rotates in the reverse direction, the two clamping jaw assemblies 120 slide in directions away from each other.

[0089] In this embodiment, please refer to Fig.10 The rotary drive member 131 specifically adopts a rotary motor with dual output ends, and the first screw segment 132 and the second screw segment 133 are independent screws. In some embodiments, the rotary drive member 131 may also adopt a rotary motor with only one output end, and the first screw segment 132 and the second screw segment 133 are two screw segments of a bidirectional screw, and the rotary motor is connected to the bidirectional screw, which can also realize the function of driving the two jaw assemblies 120 to slide toward or away from each other synchronously.

[0090] For example, please refer to Figure 9-10The clamping jaw assembly 120 further includes a supporting driving member 123 and an elastic reset member (not shown in the figure), the supporting driving member 123 is transmission-connected to the supporting plate 122, the elastic reset member is transmission-connected to the supporting plate 122, one of the supporting driving member 123 and the elastic reset member drives the supporting plate 122 to extend horizontally from the inner side of the clamping jaw plate 121, and the other drives the supporting plate 122 to retract horizontally relative to the clamping jaw plate 121. In this embodiment, the supporting driving member 123 is used to drive the supporting plate 122 to retract horizontally relative to the clamping jaw plate 121, and the elastic reset member is used to drive the supporting plate 122 to extend horizontally from the inner side of the clamping jaw plate 121, so that when clamping the plate, there is no need to continuously output an electric driving force to the supporting plate 122, which reduces the control difficulty and saves the operation cost.

[0091] For details, please refer to Figure 9-10 The supporting driving member 123 is mounted on the clamping jaw mounting plate 128, and its output end is downward and telescopically arranged in the vertical direction. The clamping jaw assembly 120 also includes a transmission plate 124 and a supporting mounting block 125. The transmission plate 124 is connected to the output end of the supporting driving member 123 and is slidably arranged on the outer side of the clamping jaw plate 121 in the vertical direction. The supporting mounting block 125 is slidably arranged on the clamping jaw plate 121 in the horizontal direction. The supporting plate 122 is fixed to the bottom of the supporting mounting block 125. The supporting mounting block 125 is provided with a wedge-shaped inclined surface 1251, and the transmission plate 124 applies pressure to the wedge-shaped inclined surface 1251. The elastic reset member can be selected as an elastic member such as a tension spring, a compression spring, etc. This embodiment is described by taking the elastic reset member using a tension spring as an example. The elastic reset member is embedded between the clamping jaw plate 121 and the supporting mounting block 125. One end of the elastic reset member is connected to the clamping jaw plate 121, and the other end is connected to the supporting mounting block 125. When the supporting driving member 123 is extended, it pushes the supporting mounting block 125 to slide horizontally away from the other clamping jaw assembly 120, and the elastic potential energy of the elastic reset member increases; when the elastic reset member releases the elastic potential energy, it drives the supporting mounting block 125 to slide toward the other clamping jaw assembly 120.

[0092] For example, please refer to Figure 9-10 A transmission roller 1241 is rotatably mounted on the lower end of the transmission plate 124, and the transmission plate 124 applies pressure to the wedge-shaped inclined surface 1251 through the transmission roller 1241 to convert the sliding friction between the transmission plate 124 and the supporting mounting block 125 into rolling friction, thereby reducing friction loss.

[0093] In some embodiments, there is no need to set up an elastic reset member, and only a supporting drive member 123 is set up. The supporting drive member 123 is connected to the supporting plate 122 in a transmission manner. The supporting drive member 123 can directly drive the supporting plate 122 to move horizontally back and forth, so as to directly drive the supporting plate 122 to extend and retract relative to the clamping claw plate 121.

[0094] For example, please refer to Figure 8-Figure 10Each clamping jaw assembly 120 includes at least two spaced-apart clamping jaw plates 121, and the plurality of clamping jaw plates 121 are mounted on the same clamping jaw mounting plate 128. A supporting plate 122 is mounted on each clamping jaw plate 121, and at least two transmission rollers 1241 are rotatably mounted on the lower end of the transmission plate 124. The plurality of supporting plates 122 are driven by the same supporting driving member 123 and the transmission plate 124 to increase the clamping and supporting points of the plate and further improve the stability. In this embodiment, each clamping jaw assembly 120 includes two spaced-apart clamping jaw plates 121.

[0095] For example, please refer to Figure 9-10 The supporting plate 122 is fixed to the bottom of the supporting mounting block 125 by fastening screws, and the operating personnel can disassemble and assemble the supporting plate 122 for replacement.

[0096] For example, please refer to Figure 8-Figure 10 The clamping jaw assembly 120 also includes a clamping pad 126 and a limiting plate 127. The clamping pad 126 is embedded in the inner side of the clamping jaw plate 121. The clamping pad 126 is made of a material with a lower hardness than that of the clamping jaw plate 121, such as silicone. The limiting plate 127 is height-adjustably installed on the inner side of the clamping jaw plate 121 through a waist-shaped connecting hole. The limiting plate 127 is pressed against the side of the clamping pad 126. The limiting plate 127 is located above the supporting plate 122 and forms a clamping gap between the two. When the clamping jaw plate 121 clamps the plate, the side of the plate extends into the clamping gap and abuts against the clamping pad 126. Specifically, the setting of the clamping pad 126 can reduce the pressure of the clamping force acting on the side edge of the plate to apply a more flexible clamping force. The limiting plate 127, on the one hand, plays a role in fixing the clamping pad 126, and on the other hand, together with the supporting plate 122, forms a clamping gap, which can assist in limiting the vertical position of the plate and further improve the stability of the clamped plate.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
