[0061] This embodiment provides a cotton pasting device for adsorbing cotton material for feeding and assembling. The cotton material can be heat-conducting cotton, buffer cotton, etc. For example, in some products, it is necessary to paste heat-conducting cotton between the PCBA board and the reinforcing rib board to play a role in buffering and assisting the heat dissipation of the PCBA board. The cotton pasting device of the present application can be used to adsorb the heat-conducting cotton and paste it onto the PCBA board, and then the downstream device will lock the reinforcing rib board to the position on the PCBA board where the heat-conducting cotton is pasted.

[0062] Please refer to Figures 1 - 13 , the cotton pasting device includes a cotton material pasting module 20, which includes a main machine table 10, a pasting module 20, a feeding module 30 and a conveying module 40. The pasting module 20, the feeding module 30 and the conveying module 40 are all installed on the main machine table 10. Among them, the feeding module 30 is used for turning over the tray 60, and the tray 60 is used for carrying the cotton material. The pasting module 20 is used to take out the cotton material from the tray 60 and paste the cotton material into the workpiece to be pasted cotton on the conveying module 40. The workpiece to be pasted cotton is placed on the workpiece carrier tray, and the conveying module 40 is used to convey the workpiece carrier tray along the horizontal first direction (i.e., the X direction in the figure).

[0063] Exemplarily, please refer to Figure 1 and Figure 2, the main machine platform 10 includes a main machine chassis 11 and a main machine module. The main machine module is installed on the main machine chassis 11. Among them, the feeding module 30 and the conveying module 40 are both installed on the main machine chassis 11. The main machine module includes a transverse movement module 12 and an electric control module (not shown in the figure). The cotton pasting module 20 is installed at the output end of the transverse movement module 12. The transverse movement module 12 can drive the cotton pasting module 20 to horizontally move along the first direction and the second direction perpendicular to each other (i.e., the Y direction in the figure). The electric control module is communicatively connected to the transverse movement module 12, the cotton pasting module 20, the feeding module 30, and the conveying module 40.

[0064] Exemplarily, the transverse movement module 12 can adopt a gantry mechanism or a cantilever structure, which can be specifically set according to the usage requirements and working conditions. Please refer to Figure 1 , the transverse movement module 12 of this embodiment adopts a cantilever structure. The transverse movement module 12 includes a fixed seat 121, a first transverse movement driving component 122, a first slide rail 123, a second slide rail 124, a sliding cross beam 125, and a second transverse movement driving component 126. Among them, two fixed seats 121 are fixed on the main machine chassis 11 and arranged at intervals along the X direction. The fixed seats 121 extend along the Y direction. At least one sliding cross beam 125 is slidably arranged along the Y direction on each fixed seat 121. The upper surface of the fixed seat 121 is provided with a first slide rail 123, and the side wall of the fixed seat 121 facing inward is provided with a second slide rail 124. One end of the sliding cross beam 125 is slidably connected to both the first slide rail 123 and the second slide rail 124 through a sliding plate portion, greatly improving the reliability of the sliding connection and the sliding control accuracy. The first transverse movement driving component 122 is installed on the sliding plate portion, and its output end is connected to the fixed seat 121 to drive the sliding cross beam 125 to slide along the Y direction. The second transverse movement driving component 126 is installed on the sliding cross beam 125, and its output end is connected to the cotton pasting module 20 to drive the cotton pasting module 20 to slide along the X direction relative to the sliding cross beam 125. Specifically, the first transverse movement driving component 122 can select a power component composed of a rotary motor and a synchronous belt pulley, a gear rack, etc. The second transverse movement driving component 126 can select a linear slide table structure arranged horizontally. The specific structures and working principles of the above power structures are all prior arts and will not be elaborated here.

[0065] Exemplarily, the cotton sticking module 20 is installed at the output end of the transverse movement module 12 in a modular form, that is, the cotton sticking module 20 is detachably connected to the transverse movement module 12 in terms of mechanical structure, and is also detachably connected to the electric control module in terms of electrical structure. Users can install cotton sticking modules 20 of different models and categories on the transverse movement module 12 as needed. Of course, the cotton sticking module 20 can also be replaced with other process modules to achieve rapid equipment adjustment and improve the flexibility and versatility of the equipment. Specifically, the cotton sticking module 20 can be detachably connected to the output end of the second transverse movement drive assembly 126 by tightening bolts, and an electrical socket is provided on the cotton sticking module 20, which is electrically connected to the electric control module through a pluggable electrical connection cable.

[0066] For example, please refer to Figure 3 The cotton sticking module 20 includes a cotton sticking mounting plate 21 and a cotton sticking mechanism 22. The cotton sticking mechanism 22 includes a double-ended rotating drive member 221, a lifting screw rod 222 and a cotton suction assembly 223. The double-ended rotating drive member 221 is fixed to the cotton sticking mounting plate 21. The lifting screw rod 222 is slidably arranged in the vertical direction on the cotton sticking mounting plate 21 or the fixed part of the double-ended rotating drive member 221. The lifting screw rod 222 is restricted in its rotational freedom around the vertical axis and cannot rotate. The lifting screw rod 222 is penetrated by the double-ended rotating drive member 221. The double-end rotary drive member 221 has a first output end 2211 and a second output end 2212. The first output end 2211 and the second output end 2212 can both independently output rotary power, and the direction of the rotary power is around the vertical axis. The first output end 2211 is threadedly connected to the lifting screw rod 222 through a nut structure, and the cotton suction component 223 is slidably installed on the second output end 2212 along the vertical direction. The lower end of the lifting screw rod 222 is transmission-connected to the cotton suction component 223. The cotton suction component 223 can rotate under the drive of the second output end 2212 and can also be lifted and lowered under the drive of the lifting screw rod 222. The cotton suction component 223 is used for vacuum absorption of cotton material.

[0067] Specifically, the cotton sticking mechanism 22 drives the cotton suction assembly 223 to upgrade and rotate by setting a double-end rotating drive member 221. The double-end rotating drive member 221 has a first output end 2211 and a second output end 2212, which respectively output the lifting driving force and the rotation driving force. On the one hand, the first output end 2211 is threadedly connected to the lifting screw rod 222 through a nut structure, and can drive the lifting screw rod 222 to move in the vertical direction to drive the cotton suction assembly 223 to lift and lower. On the other hand, the cotton suction assembly 223 is slidably installed on the second output end 2212 in the vertical direction, and while allowing the cotton suction assembly 223 to lift and lower freely, it can drive the cotton suction assembly 223 to rotate around the vertical axis. It can be seen that the cotton sticking module 20 outputs lifting power and rotation power to the cotton suction assembly 223 through the double-end rotating drive member 221. Its structure is simple and compact, and it can drive the cotton material to lift and rotate at the same time, which helps to improve the working efficiency.

[0068] The double-ended rotary drive member 221 can adopt drive elements such as a dual-axis motor or a dual-rotor motor with two independently arranged output shafts. In this embodiment, the double-ended rotary drive member 221 adopts a dual-axis motor. The first output end 2211 is a rotary shaft arranged vertically upward, and the second output end 2212 is a rotary shaft arranged vertically downward. The two are coaxially arranged. Both the first output end 2211 and the second output end 2212 are arranged as hollow structures so that the lifting lead screw 222 can pass through coaxially. Among them, a lead screw nut is fixed at the end of the first output end 2211, or internal threads are provided in the central through hole of the first output end 2211 to threadedly connect the lifting lead screw 222.

[0069] Exemplarily, please continue to refer to Figure 3 The cotton pasting mechanism 22 further includes a telescopic sleeve 224. The telescopic sleeve 224 is telescopically installed on the second output end 2212 in the vertical direction. The lower end of the telescopic sleeve 224 is connected to the cotton suction assembly 223. The lower end of the lifting lead screw 222 penetrates into and is clamped to the telescopic sleeve 224, and can drive the telescopic sleeve 224 to telescopically move in the vertical direction. At the same time, the telescopic sleeve 224 can rotate relative to the lifting lead screw 222 around the vertical axis, and the rotation actions of the two do not interfere with each other. Specifically, the telescopic sleeve 224 can be a rigid structural member installed on the second output end 2212 by means of a sliding connection. The lower end of the lifting lead screw 222 realizes power transmission in the vertical direction with the telescopic sleeve 224 through the insertion and cooperation of an annular groove and a transmission flange. When the first output end 2211 rotates, the lifting lead screw 222 drives the telescopic sleeve 224 and the cotton suction assembly 223 to lift together; the telescopic sleeve 224 can also adopt an elastic structural member that can elastically expand and contract in the vertical direction. Its upper end is connected to the second output end 2212, and the lower end is connected to the cotton suction assembly 223. When the first output end 2211 rotates, the lifting lead screw 222 drives the telescopic sleeve 224 to vertically expand and contract, and the cotton suction assembly 223 lifts and lowers with the lifting lead screw 222.

[0070] It can be understood that the cotton suction assembly 223 needs to be connected to a vacuum generating device such as a vacuum pump so that the cotton suction assembly 223 has adsorption force. Usually, the cotton suction assembly 223 needs to be connected to the vacuum generating device through an air pipe 24. Exemplarily, please continue to refer to Figure 3 The cotton pasting module 20 further includes a vacuum valve assembly 23. The vacuum valve assembly 23 is connected to the air extraction hole of the cotton suction assembly 223 through the air pipe 24, and the vacuum valve assembly 23 is further connected to an external vacuum generating device. The vacuum valve assembly 23 controls the vacuum adsorption action of the cotton suction assembly 223.

[0071] Since the cotton suction assembly 223 needs to move, at this time, the air pipe 24 is prone to problems such as winding or abrasion of the air pipe 24 during the movement of the cotton suction assembly 223. Based on this, please continue to refer to Figure 3, a middle through hole is provided in the lifting screw rod 222 and runs through it along its axis direction. The lower end of the middle through hole is communicated with the air extraction hole of the cotton suction assembly 223, and the upper end of the middle through hole is connected to the vacuum valve assembly 23 through a trachea 24. In some embodiments, the trachea 24 between the cotton suction assembly 223 and the vacuum valve assembly 23 can also be directly passed through the middle through hole of the lifting screw rod 222. In this way, by setting the lifting screw rod 222 as a hollow structure, the movement amplitude of the trachea 24 can be greatly reduced or the exposed ratio of the trachea 24 can be decreased, solving the problems of winding or abrasion of the trachea 24 and improving the operation stability of the equipment.

[0072] Generally, cotton materials have various shapes and structures. Correspondingly, the adsorption assembly also needs to be provided with a specific adsorption structure to match it. Please refer to Figures 3 - 5 , the cotton suction assembly 223 includes a vacuum suction nozzle 2231 and a cotton suction jig 2232. The vacuum suction nozzle 2231 is installed at the second output end 2212. The cotton suction jig 2232 is connected to the cotton suction jig 2232. A transfer air hole 22321 and a plurality of material suction holes 22322 connected through an air passage are provided on the cotton suction jig 2232. One end of the vacuum suction nozzle 2231 is communicated with the lower end of the middle through hole, and the other end is communicated with the transfer air hole 22321. In this embodiment, the cotton suction jig 2232 is set as a long strip structure, and a plurality of material suction holes 22322 arranged in a straight line are provided thereon to adapt to the long strip-shaped cotton material.

[0073] Exemplarily, please continue to refer to Figures 3 - 5 , the cotton suction assembly 223 further includes a mounting block 2233. The cotton suction jig 2232 is detachably connected to the vacuum suction nozzle 2231 through the mounting block 2233. When the user adjusts the adsorption assembly according to the change of the cotton material type, the cotton suction jig 2232 can be replaced separately without disassembling the whole adsorption assembly. On the one hand, it is convenient for operation and improves efficiency. On the other hand, the number of spare parts is reduced, and the spare parts cost and management cost are decreased.

[0074] Exemplarily, please refer to Figure 4 and Figure 5The mounting block 2233 is provided with a mounting plane 22331 on one side away from the vacuum nozzle 2231, and the cotton suction fixture 2232 is installed on the mounting plane 22331. The mounting block 2233 is also provided with a mounting through hole 22332 penetrating the mounting plane 22331 along its thickness direction, at least two fastening holes 22333 and an adjustment hole 22334. Among them, the vacuum suction nozzle 2231 is threadedly connected to the mounting through hole 22332, and the mounting through hole 22332 is connected to the adapter air hole 22321; the fastening holes 22333 are distributed on both sides of the mounting through hole 22332, and the mounting block 2233 is connected to the cotton suction jig 2232 by a fastener (not shown in the figure) passing through the fastening hole 22333; the adjustment hole 22334 can be selectively installed with an adjustment part (not shown in the figure), one end of the adjustment part is protruded on the mounting plane 22331 and pressed against the cotton suction jig 2232, and the protruding height of the adjustment part can be adjusted to adjust the angle between the cotton suction jig 2232 and the horizontal plane. Specifically, the central axis of the installation through hole 22332 is arranged to coincide with the central line of the installation block 2233. The installation block 2233 is provided with four fastening holes 22333. Two fastening holes 22333 are respectively distributed on the left and right sides of the installation through hole 22332. The fasteners may be screws or pins. The fasteners pass through the fastening holes 22333 and are locked to the connection holes on the cotton suction fixture 2232. The setting of multiple connection points improves the installation reliability of the cotton suction fixture 2232. Adjustment holes 22334 are also distributed on the left and right sides of the installation through hole 22332. By selectively installing adjustment parts and adjusting the protruding heights of the adjustment parts on both sides, the tilt direction and angle of the cotton suction fixture 2232 can be adjusted, so that the cotton suction component 223 has a higher adaptability in absorbing cotton materials.

[0075] For example, please refer to Figure 3 At least two cotton sticking mechanisms 22 are installed side by side on the cotton sticking installation plate 21, which can perform adsorption and sticking operations on multiple cotton materials at the same time. In this embodiment, two cotton sticking mechanisms 22 that can work independently are installed side by side on the cotton sticking installation plate 21.

[0076] Exemplarily, the cotton pasting module 20 further includes a cotton pasting detection device installed on the cotton pasting installation plate 21, which is used to detect the positions of the cotton material and the workpiece to be pasted with cotton. The cotton pasting detection device can be a visual detection device and a laser displacement sensor.

[0077] For the mainframe chassis 11, please refer to Figure 1, the mainframe chassis 11 has an upper tabletop and a lower tabletop. The conveying module 40 includes a forward conveying mechanism 41 and a return conveying mechanism 42. The forward conveying mechanism 41 is arranged on the upper layer of the mainframe chassis 11 and is used to convey the fixture carrying the cotton-attaching workpiece. The return conveying mechanism 42 is arranged on the lower layer of the mainframe chassis 11 and is used to convey the empty workpiece carrier. The conveying direction of the return conveying mechanism 42 is opposite to that of the forward conveying mechanism 41. The conveying direction of the forward conveying mechanism 41 is the same as the X direction, and the conveying direction of the return conveying mechanism 42 is opposite to the X direction. The cotton-attaching device can cooperate with the conveying lines and workpiece carrier lifting devices on other devices in the automated production line to automatically circulate and turnover the workpiece carriers, further improving the degree of automation. Specifically, both the forward conveying mechanism 41 and the return conveying mechanism 42 can adopt the single-track or double-track conveying line structure in the prior art, and their specific structures will not be elaborated here.

[0078] Exemplarily, please refer to Figure 2 , the mainframe table 10 further includes a machine cover 13 and a liftable machine door 14. The machine cover 13 is installed above the mainframe chassis 11 and covers the traversing module 12 and the electric control module. The liftable machine door 14 is slidably arranged along the vertical direction on the side of the machine cover 13 to selectively open the side opening of the machine cover 13. The liftable machine door 14 is provided with an interactive panel and / or control buttons electrically connected to the electric control module for the operator to control the cotton-attaching device. Specifically, for equipment maintenance, replacement and other work, the machine cover 13 is provided with a machine door that is often opened and closed. The traditional machine door is generally a double-opening door or a flip-up door. However, these two types of doors will occupy the side space of the equipment when opened, resulting in a large production space occupied by the equipment, easy to cause bumping problems and potential safety hazards. The liftable machine door 14 of the present application can automatically move up or down in the vertical direction, avoiding occupying the side space of the equipment, so that the production space occupied by the equipment is small, avoiding bumping and having higher safety. It can be understood that the liftable machine door 14 can be composed of a fixed frame, a liftable 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 liftable door body, and the transmission member is sequentially wound 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 up synchronously, thereby driving the liftable door body to move up. When the driving wheel rotates reversely, the upper and lower ends of the transmission member move down synchronously, thereby driving the liftable door body to move down.

[0079] Exemplarily, please refer to Figures 1 - 2Upper avoidance openings 131 are provided on opposite sides of the hood 13 for the workpiece carrier conveyed by the forward conveying mechanism 41 to pass in or out; lower avoidance openings 111 are provided on opposite sides of the main frame 11 for the workpiece carrier conveyed by the reflux conveying mechanism 42 to pass in or out.

[0080] For example, at least two loading stations are provided on the main machine 10, each of which is provided with a feeding module 30 and a cotton pasting station. The cotton pasting module 20 moves between the loading station and the cotton pasting station to achieve simultaneous loading and pasting of multiple stations, thereby improving the working efficiency. Figure 1 Two loading stations are symmetrically arranged at both ends of the main platform 10 in the Y direction, and U-shaped openings are provided on the opposite sides of the main frame 11 for the feeding module 30 to be loaded. Each loading station is correspondingly provided with two cotton sticking stations distributed along the X direction, and each cotton sticking station is provided with a cotton sticking module 20. The first transverse movement drive assembly 122, the sliding beam 125 and the second transverse movement drive assembly 126 in the transverse movement module 12 are arranged in a one-to-one correspondence with the cotton sticking module 20. The conveying module 40 is also symmetrically arranged in two groups, and each forward conveying mechanism 41 is correspondingly provided with two cotton sticking stations distributed along the X direction. The two lifting doors 14 are respectively arranged corresponding to the two loading stations, which is convenient for the staff to observe and debug the equipment.

Specifically, the cotton pasting lighting module 50 includes a light source mounting frame 51 and a ring light source 52. The light source mounting frame 51 is fixed above the frame of the forward conveying mechanism 41. The ring light source 52 is installed on the light source mounting frame 51 in a ring structure, and a high-brightness lighting area is formed on the central side of the ring light source 52. When pasting cotton, the workpiece to be pasted is located in the lighting area.

[0082] For the feeding module 30, the feeding module 30 is installed on the side of the main frame 11 in a modular form, that is, the feeding module 30 and the main frame 11 can be detachably connected in terms of mechanical structure and electrical structure. The user can install different types of feeding modules 30 on the main frame 11 as needed to achieve rapid equipment adjustment and improve the flexibility of the cotton sticking equipment.

When the feeding module 30 needs to be detached, the feeding module 30 is dragged in the reverse direction to gradually disengage from the U-shaped opening.

[0084] Exemplarily, one of the mainframe chassis 11 and the feeding module 30 is provided with a first positioning portion (not shown in the figure), and the other is provided with a second positioning portion (not shown in the figure). When the feeding module 30 moves to the installation position where it is docked with the mainframe chassis 11, the first positioning portion is structurally connected to the second positioning portion, so that the feeding module 30 is completely fixed to the mainframe chassis 11. In this embodiment, the first positioning portion is provided on the mainframe chassis 11, and the second positioning portion is provided on the feeding module 30. Both the first positioning portion and the second positioning portion are provided as positioning hole structures.

An electrical plug is provided on the feeding module 30. When the electrical plug is inserted into the electrical socket, the electronic control module is electrically connected to the feeding module 30.

[0086] Exemplarily, the feeding module 30 is used to convey the tray 60 and cooperate with the cotton pasting module 20. After the cotton pasting module 20 takes out all the cotton materials from the tray 60, the empty tray 60 is recycled, and a new full tray 60 is replenished, so as to achieve the purpose of automatically replacing the tray 60.

[0088] Specifically, the two material suction stations 302 can be used for the cotton pasting module 20 to alternately pick materials from the two trays 60 or pick materials at the same time. After the tray 60 is empty, the transverse transfer device 32 drives the tray 60 to move from the material suction station 302 to the recycling station 301.

[0107] It can be understood that the lifting and conveying mechanism 37 corresponding to the recycling station 301 is used to drive the pallet 60 on the recycling station 301 to descend and move out from the lower layer frame 312, and the lifting and conveying mechanism 37 corresponding to the material suction station 302 is used to drive the pallet 60 to be loaded into the lower layer frame 312 and rise to the material suction station 302.

[0108] Specifically, below the material suction station 302, the staff puts multiple pallets 60 carrying workpieces through the avoidance opening. The multiple pallets 60 are stacked layer by layer. The horizontal conveying component drives the multiple pallets 60 to horizontally move into the inner end. At this time, the lifting table component 372 descends below the supporting surface of the horizontal conveying component. Subsequently, the lifting table component 372 rises, driving the multiple pallets 60 to rise, so that the uppermost pallet 60 reaches the material suction station 302. The chuck device 33 clamps the uppermost pallet 60. At this time, the lifting table component 372 drives the remaining pallets 60 to descend a certain height to separate them from the pallet 60 clamped by the chuck device 33. After the workpieces on the pallet 60 are loaded, the transverse transfer device 32 drives the pallet 60 to move to the recycling station 301. The lifting table component 372 arranged below the material suction station 302 continues to push the next pallet 60 up to the material suction station 302 to realize the function of layer-by-layer loading. The transverse transfer device 32 can alternately transfer the pallets 60 on the two material suction stations 302 to the recycling station 301. The lifting table component 372 arranged below the recycling station 301 receives the pallet 60 released by the chuck device 33. For each received pallet 60, the lifting table component 372 descends a certain height to realize the function of layer-by-layer recycling of the pallets 60. When the number of pallets 60 to be recycled reaches the preset value, the lifting table component 372 descends to the lowest point, and the corresponding horizontal conveying component conveys the multiple pallets 60 and drives the multiple pallets 60 to be sent outwards through the avoidance opening, so that the staff can recycle multiple pallets 60 at the same time.

[0109] Exemplarily, please refer to Figure 6 , the adjacent lifting and conveying mechanisms 37 are separated by the isolation sheet metal 373, forming three conveying cavities in the lower layer frame 312 to ensure that each lifting and conveying mechanism 37 independently conveys the pallet 60, restricts the lateral position of the pallet 60, avoids the side slip of the pallet 60, and further improves the reliability. On the side close to the avoidance opening, the isolation sheet metal 373 is provided with an avoidance inclined surface 3731 to make the conveying cavity form a horn-shaped docking port, which is convenient for the entry and exit of the pallet 60.
