[0028] In order to explain the technical content, purpose and effect of the present invention in detail, the following is a description of the embodiments and the accompanying drawings. It should be noted that the words "upper" and "lower" used in the following description refer to the attached Figure 4 In the directions, the words "bottom" and "top" refer to the Figure 4 The direction towards the geometric center of a specific component.

[0029] The most critical concept of the present invention is that: through the turntable 7, the rotating drive member and the multiple fixing seats 8, the multiple bottom frame wood strips 1 are limited and fixed and the multiple bottom frame wood strips 1 are conveyed at the same time; through the hole detection device and the alarm, it is played to automatically detect whether the bottom frame wood strips 1 to be assembled are qualified; through the first infrared sensor 11, the magnet feeding device and the multiple feeding ports of the magnet feeding device, it is played to automatically detect whether there are bottom frame wood strips 1 and automatically assemble and place magnet pieces 3 in the bottom frame wood strips 1; through a group of glue dispensers 12 and lifting drive members, it is played to automatically apply glue to the upper surface of the magnet piece 3 and the wood piece installation groove 6; through the lifting drive member, the translation mechanism 13, the wood piece feeding device and the multiple feeding ports of the wood piece feeding device, it is played to automatically fix and assemble the wood cover piece 4 and the magnet piece 3 in the bottom frame wood strip 1; through the baking device, it is played to automatically accelerate the solidification of the glue; through the discharging device, it is played to automatically convey the assembled and fixed bottom frame wood strips 1 to the next process.

[0030] The overall automation level of the present invention is high. Compared with assembly line assembly, it occupies a small area. In the subsequent assembly process, there is no need for manual fixing and carrying of the bottom frame wood strips 1. At the same time, it avoids the occurrence of errors and visual fatigue caused by manual naked eye observation, which affects the subsequent assembly speed and consumes more manpower. It has the advantages of high assembly efficiency, low labor intensity and high safety.

[0031] Please refer to Figures 2 to 10 As shown, an automatic assembly machine for decorative wooden frames comprises a turntable 7, a rotating driving member for driving the turntable 7 to rotate, a hole detection device, a magnet unloading device, a wood chip unloading device, a baking device and a discharging device arranged in sequence along the rotation direction of the turntable 7, the hole detection device is used to detect whether there are magnet mounting holes 5 and wood chip mounting grooves 6 in the bottom frame wood strip 1, a plurality of fixing seats 8 are evenly arranged on the turntable 7, and a fixing groove 9 for placing the bottom frame wood strip 1 is opened on the fixing seat 8; an alarm 10 is arranged on one side of the hole detection device, and the magnet unloading device is arranged near the turntable 7. A first infrared sensor 11 for detecting whether there is a bottom frame wood strip 1 is provided on one side of the disk 7. The wood chip unloading device and the magnet unloading device are both provided with a plurality of unloading ports corresponding to the magnet mounting holes 5 and the wood chip mounting grooves 6 respectively. A group of glue dispensers 12 located above the fixed seat 8 are provided on the side of the wood chip unloading device close to the turntable 7. A lifting drive member for driving the glue dispenser 12 and the wood chip unloading device to lift and lower, and a translation mechanism 13 for driving the lifting drive member, the glue dispenser 12, and the wood chip unloading device to move toward the fixed seat 8 are also provided outside the turntable 7.

[0032] From the above description, it can be known that when it is necessary to assemble and fix the magnet sheet 3 and the wooden cover sheet 4 in the bottom frame wood strip 1, first, the bottom frame wood strip 1 to be assembled is placed in the fixing groove 9 on the fixing seat 8 through the turntable 7, the rotating drive member and the multiple fixing seats 8. At this time, the wood piece mounting groove 6 of the bottom frame wood strip 1 is on the top and the magnet mounting hole 5 is on the bottom. The rotating drive member is started to drive the multiple bottom frame wood strips 1 to be assembled to be transported in the direction of the hole detection device in sequence, which plays the role of limiting and fixing the multiple bottom frame wood strips 1 and transporting the multiple bottom frame wood strips 1 at the same time, avoiding the need for manual fixing and transportation of the bottom frame wood strips 1 in the subsequent assembly process, thereby improving the overall assembly efficiency and reducing the labor intensity; then, when the bottom frame wood strip 1 to be assembled is transported to the hole detection device, the hole detection device and The alarm is used, and the external controller controls the hole detection device to start, and uses the hole detection device to detect whether the bottom frame wood strip 1 to be assembled, which is moved to the bottom of the hole detection device, is provided with a magnet mounting hole 5 and a wood chip mounting groove 6. If it is detected that there is no magnet mounting hole 5 or a wood chip mounting groove 6 in the bottom frame wood strip 1 to be assembled, the external controller controls the alarm to sound an alarm, and uses an external manipulator or manual labor to remove the unqualified bottom frame wood strip 1. The alarm is used to remind the staff to re-drill holes or recycle and scrap the unqualified bottom frame wood strip 1 that has been removed, so as to automatically detect whether the bottom frame wood strip 1 to be assembled is qualified; it avoids the situation that the detection is prone to errors and visual fatigue caused by manual naked eye observation, which affects the subsequent assembly speed and consumes more manpower, thereby further improving the assembly efficiency and reducing the labor intensity;

[0033] Then, through the first infrared sensor 11 and the magnet feeding device, when the first infrared sensor 11 detects that the bottom frame wood strip 1 is transported to the magnet feeding device, the first infrared sensor 11 sends the detected signal to the external controller, and the external controller controls the magnet feeding device to start, and the magnet feeding device is used to feed the magnet pieces 3 from the feeding ports of several magnet feeding devices in sequence to the magnet mounting holes 5 corresponding to the bottom frame wood strip 1. When the first infrared sensor 11 detects that there is no bottom frame wood strip 1, the magnet feeding device and The subsequent glue dispenser 12, the first lifting mechanism, and the wood chip unloading device are all not started, which plays the role of automatically detecting the presence of the bottom frame wood strip 1 and automatically assembling the magnet sheet 3 in the bottom frame wood strip 1; afterwards, when the bottom frame wood strip 1 equipped with the magnet sheet 3 rotates to the wood chip unloading device station along with the turntable 7, through a group of glue dispensers 12, lifting drive parts, translation mechanism 13 and wood chip unloading device, the lifting drive parts are started first, driving the glue dispenser 12 to descend in the direction of the fixed seat 8 until it descends to a preset height. At this time, the glue dispenser 12 is located at the wood chip installation position. A small distance is preset above the mounting groove 6, and the distance is convenient for the glue dispenser 12 to apply glue to the wood chip mounting groove 6 and the magnet sheet 3. The glue dispenser 12 is started. After the glue dispenser 12 applies glue to the wood chip mounting groove 6 and the magnet sheet 3, the lifting drive member drives the glue dispenser 12 and the wood chip unloading device to rise and reset together, and then the translation mechanism 13 is started. The driving end of the translation mechanism 13 drives the glue dispenser 12, the lifting drive member and the wood chip unloading device to move along the radial direction of the turntable 7 toward the turntable 7 until the wood chip unloading device is located at the turntable 7. When the fixing seat 8 is above the fixing seat 8, the lifting driving member descends, driving the wood chip unloading device and the glue dispenser 12 to descend until the aforementioned preset height is descended, and the external controller controls the wood chip unloading device to start, and the wood chip unloading device is used to press down multiple single wood cover sheets 4 from the unloading ports of several wood chip unloading devices in sequence and convey them to the corresponding wood chip installation holes. Each wood cover sheet 4 is adhered to the wood chip installation hole and the magnet sheet 3 through the glue in the corresponding wood chip installation hole, so as to automatically fix and assemble the wood cover sheet 4 and the magnet sheet 3 in the bottom frame wood strip 1;

[0034] Afterwards, the bottom frame wood strips 1 assembled with the wooden cover pieces 4 and the magnet pieces 3 are conveyed to the baking device along with the turntable 7. By starting the baking device, the glue in the magnet mounting holes 5 and the wood chip mounting grooves 6 is baked and heated by the baking device to accelerate the solidification of the glue. It should be noted that the baking temperature and time preset by the baking device ensure that the glue is eventually in a state of almost complete solidification without being dried and evaporated, thereby automatically accelerating the solidification of the glue. Finally, the assembled and fixed bottom frame wood strips 1 are conveyed to the next splicing process through the discharging device, thereby automatically conveying the assembled and fixed bottom frame wood strips 1 to the next process.

[0035] Furthermore, the magnet unloading device includes a material box 14 and a first longitudinal linear guide rail 15 for driving the material box 14 to rise and fall. The material box 14 is detachably connected to a slider of the first longitudinal linear guide rail 15. The material box 14 is provided with a plurality of storage troughs 16 for vertically stacking single magnet sheets 3. The number of storage troughs 16 is the same as the number of magnet mounting holes 5 of a single bottom frame wood strip 1. One side of the bottom of the storage trough 16 is connected with a plurality of first discharge pipes 17 for horizontally passing through only a single magnet sheet 3. The bottom of the first discharge pipe 17 away from the material box 14 is provided with a material for unloading the magnet sheet 3 and A first discharge port 18 is located directly above the magnet mounting hole 5. The first discharge port 18 is a discharge port of the magnet discharge device. The material box 14 is installed with a first translation cylinder 19. The top rod of the first translation cylinder 19 is connected to a connecting rod 20. The connecting rod 20 is connected to a plurality of first push rods 21 for pushing the magnet sheet 3 from the bottom of the storage trough 16 to the first discharge port 18. A first clearance hole 22 for the first push rod 21 to pass through is opened on the other side of the bottom of the storage trough 16. The length of the first push rod 21 is greater than the sum of the length of the first discharge pipe 17 and the thickness of the material box 14.

[0036] From the above description, it can be known that when the first infrared sensor 11 detects that the wood strips 1 with the bottom frame are conveyed to the magnet unloading device, the first infrared sensor 11 sends the detected signal to the external controller (not shown in the figure, the same as in the full text), and the external controller controls the motor of the first longitudinal linear guide 15 to start, and the slider of the first longitudinal linear guide 15 drives the material box 14, the first discharge pipe 17, the first translation cylinder 19 and the first push rod 21 to descend toward the direction close to the fixed seat 8 until they descend to the bottom of the first unloading port 18 and contact with the bottom of the wood chip mounting groove 6, and then start the first translation cylinder 19, and the first translation cylinder 19 and the first push rod 21 are driven to move. The top rod of the air cylinder 19 is extended, driving multiple first push rods 21 to work together. The first push rod 21 pushes a magnet sheet 3 at the bottom of the corresponding storage tank 16 into the first discharge pipe 17 until the magnet sheet 3 is pushed to the first discharge port 18. The first translation cylinder 19 drives the first push rod 21 to reset. Under the action of gravity, the magnet sheet 3 falls into the magnet mounting hole 5 through the first discharge port 18, which automatically and simultaneously assembles each magnet sheet 3 and places it in the corresponding magnet mounting hole 5. Compared with manually placing the magnet sheets 3 in the magnet mounting hole 5 one by one, the assembly efficiency is fast and the assembly accuracy is high.

[0037] Furthermore, the fixing seat 8 is detachably connected to the turntable 7, and the bottom of the fixing groove 9 is provided with several groups of positioning magnets 23 for magnetically attracting the magnet sheet 3. The magnetic properties of the positioning magnets 23 are opposite to those of the magnet sheet 3. Each group of positioning magnets 23 is respectively located below both sides of the magnet mounting hole 5, and the magnetic attraction force of the positioning magnets 23 is smaller than the material picking force of the discharging device.

[0038] From the above description, it can be seen that when the magnet sheet 3 is pushed to the first discharge port 18, the first translation cylinder 19 drives the first push rod 21 to reset, and under the action of gravity and the magnetism of the positioning magnet 23, the magnet sheet 3 falls through the first discharge port 18 and is adsorbed in the magnet mounting hole 5, which automatically and simultaneously assembles each magnet sheet 3 and places it in the corresponding magnet mounting hole 5.

[0039] Furthermore, the material box 14 is equipped with a first electric push rod 24 located above the first discharge pipe 17, the top rod of the first electric push rod 24 is connected to the first connecting plate 25, and the bottom of the first connecting plate 25 is detachably connected to a plurality of wooden pressing blocks 26 for pressing the magnet sheet 3 into the magnet mounting hole 5. The number of wooden pressing blocks 26 is the same as the number of magnet mounting holes 5 of a single bottom frame wooden strip 1, and a first through hole 27 is opened at the top of the first discharge pipe 17, which is connected to the first discharge port 18 and for the wooden pressing blocks 26 to pass through.

[0040] From the above description, it can be seen that when the magnet piece 3 is pushed to the first discharge port 18, the first electric push rod 24 is started, and the top rod of the first electric push rod 24 extends downward, driving the first connecting plate 25 to move downward, thereby driving multiple wooden pressing blocks 26 to pass through the first through holes 27 corresponding to the first discharge pipe 17 and enter the first discharge pipe 17. After entering the first discharge pipe 17, the wooden pressing blocks 26 press the falling magnet piece 3 down into the magnet mounting hole 5 to ensure that the magnet piece 3 falls completely into the magnet mounting hole 5, and the bottom of the magnet piece 3 is tightly fitted with the bottom of the magnet mounting hole 5 to avoid the magnet piece 3 being stuck in the first discharge port 18 and affecting the assembly speed of the magnet piece 3. Afterwards, the first electric push rod 24 drives the wooden pressing blocks 26 to rise and reset, and the assembly of the magnet piece 3 can be completed, which plays a role in further improving the assembly efficiency and assembly accuracy.

[0041] Furthermore, the hole detection device includes a shading frame 28, an LED lamp 29, an industrial camera 30 and a group of second infrared sensors 31 for detecting whether the bottom frame wood strip 1 has a magnet mounting hole 5. The LED lamp 29 is installed in the middle position of the top of the shading frame 28, the industrial camera 30 is installed on both sides of the top of the shading frame 28, the industrial camera 30 is electrically connected to an industrial computer, and the shading frame 28 is connected to a photoelectric switch 32 for detecting whether there is a bottom frame wood strip 1 in the fixed seat 8 on the side away from the magnet unloading device. A fixed disc 33 is provided under the turntable 7, and a circular hole is provided in the middle of the fixed disc 33 for the upper end of the rotating drive member to pass through. The turntable 7 and the fixed seat 8 are both provided with a makeshift through hole 34 that communicates with the magnet mounting hole 5. The second infrared sensor 31 is installed on the fixed disc 33, and a collection box for collecting waste glue is detachably installed at the bottom of the fixed disc 33.

[0042] From the above description, it can be known that when the bottom frame wood strip 1 to be assembled is about to be transported to the hole detection device, the photoelectric switch 32 detects the signal of the bottom frame wood strip 1 to the external controller, and the external controller controls the second infrared sensor 31 and the industrial camera 30 to start, and uses the industrial camera 30 to collect image information of the bottom frame wood strip 1, and sends the captured image information to the industrial computer. The industrial computer first compares and classifies the image with the preset picture to determine whether there is a wood chip installation groove 6, and uses the second infrared sensor 31 to detect whether there is an obstacle above the clearance through hole 34, and whether the infrared rays emitted by the second infrared sensor 31 are completely blocked, that is, if there is no magnet installation hole 5, it is detected that there is an obstacle above the clearance through hole 34. Thereby, the function of automatically detecting whether the bottom frame wood strip 1 is provided with the magnet mounting hole 5 and the wood chip mounting groove 6 is realized; a fixed disc 33 is utilized, and the fixed disc 33 does not rotate with the turntable 7, so as to facilitate the installation and placement of the second infrared sensor 31; a detachable collection box is utilized to collect a little residual waste glue flowing down from the magnet mounting hole 5 when the glue is applied, so as to avoid the need to manually use tools to clean up the waste glue later, thereby further reducing the labor intensity; a light shielding frame 28 and an LED lamp 29 are used to illuminate the bottom frame wood strip 1, and at the same time, one side light is shielded to avoid the recognition accuracy of the image of the bottom frame wood strip 1 being affected by the changeable light of the external environment, thereby further improving the detection accuracy of the hole.

[0043] Furthermore, the baking device includes a bracket 35, a first lifting cylinder 36 and a plurality of electric heating rods 37 for accelerating the solidification of glue at the magnet sheet 3. The first lifting cylinder 36 is installed on the bracket 35. The top rod of the first lifting cylinder 36 is connected to a lower pressure plate 38 for pressing down the wooden cover sheet 4; the electric heating rods 37 are located on the lower pressure plate 38 and are installed on the fixed disc 33.

[0044] From the above description, it can be known that when the bottom frame wood strip 1 assembled with the wood cover piece 4 and the magnet piece 3 is transported to the baking device along with the turntable 7, the external controller first controls the top rod of the first lifting cylinder 36 to extend downward, driving the lower pressing plate 38 to further press the wood cover piece 4 downward, so that the bottom of the wood cover piece 4 is in close contact with the glue, and then starts the electric heating rod 37. The heat generated by the electric heating rod 37 enters the magnet mounting hole 5 through the yield through hole 34, and the heat is used to bake and heat the glue in the magnet mounting hole 5 and the wood chip mounting groove 6 to accelerate the solidification of the glue until the preset top time is reached. At this time, the glue is almost completely solidified, but will not be dried and evaporated. The residual heat of the electric heating rod can continue to heat the glue, which automatically accelerates the solidification of the glue.

[0045] Furthermore, the wood chip unloading device includes a mounting plate 39 and a plurality of storage tubes 40 for vertically stacking single wood cover sheets 4. The storage tubes 40 are detachably mounted on one side of the mounting plate 39. The number of the storage tubes 40 is the same as the number of the wood chip mounting grooves 6 of the single bottom frame wood strip 1. The bottom side of the storage tube 40 is connected with a plurality of second discharge tubes 41 for horizontally passing through only single wood cover sheets 4. The bottom of the second discharge tube 41, which is away from the storage tube 40, is provided with a second lower discharge tube 41 for unloading the wood cover sheets 4 and located directly above the wood chip mounting groove 6. The material port 42, the second material port 42 is the material port of the wood chip material feeding device, and a second translation cylinder 43 is installed on the side of the mounting plate 39 away from the second discharge pipe 41, and the top rod of the second translation cylinder 43 is connected with a plurality of second push rods 44 for pushing the magnet sheet 3 from the bottom of the storage trough 16 to the second material port 42. A second clearance hole 45 for the second push rod 44 to pass through is opened on the other side of the bottom of the storage pipe 40, and the length of the second push rod 44 is greater than the sum of the length of the second discharge pipe 41 and the thickness of the storage pipe 40.

[0046] From the above description, it can be known that when the bottom frame wood strip 1 equipped with the magnet sheet 3 is transported to the wood chip unloading device, the glue dispenser 12 completes the coating of glue, and the driving end of the translation mechanism 13 drives the wood chip unloading device to move to the top of the corresponding fixed seat 8, the lifting drive member descends, driving the wood chip unloading device and the glue dispenser 12 to descend, until they descend to the bottom of the second unloading port 42 at the notch of the wood chip mounting slot 6, the external controller controls the second translation cylinder 43 to start, the top rod of the second translation cylinder 43 extends, and drives multiple first translation cylinders 43 to move upward. The two push rods 44 work together, and the second push rod 44 pushes a piece of wooden cover piece 4 at the bottom of the corresponding storage tube 40 into the second discharge tube 41 until the wooden cover piece 4 is pushed to the second discharge port 42. Under the action of gravity, the wooden cover piece 4 falls into the wooden cover piece 4 installation groove through the second discharge port 42, which plays the role of automatically and simultaneously assembling multiple single wooden cover pieces 4 and placing them in the corresponding magnet installation holes 5; compared with manually placing the wooden cover pieces 4 one by one in the wooden piece installation groove 6, the assembly efficiency is fast and the assembly accuracy is high.

[0047] Furthermore, a second electric push rod 46 is installed on the top outside the second discharge pipe 41, and the top rod of the second electric push rod 46 is connected to the second connecting plate 47. The bottom of the second connecting plate 47 is detachably connected with a plurality of electric heating push blocks 48 for pressing the magnet sheet 3 into the magnet mounting hole 5. The number of the electric heating push blocks 48 is the same as the number of the wood sheet mounting grooves 6 of a single bottom frame wood strip 1. A second through hole 49 is opened on the top of the second discharge pipe 41, which is connected to the second discharge port 42 and through which the power heating push block 48 and the wires pass.

[0048] As can be seen from the above description, when the wooden cover piece 4 is pushed to the second discharge port 42, the second electric push rod 46 is started, and the top rod of the second electric push rod 46 extends downward, driving the second connecting plate 47 to move downward, thereby driving a plurality of electric heating push blocks 48 to respectively pass through the second through holes 49 corresponding to the second discharge pipe 41 and enter the second discharge pipe 41. After the electric heating push blocks 48 enter the second discharge pipe 41, they press the falling wooden cover piece 4 down into the wooden piece installation groove 6, ensuring that the wooden cover piece 4 completely falls into the wooden piece installation groove 6, and the bottom of the wooden cover piece 4 is tightly fitted with the bottom of the wooden piece installation groove 6. , avoiding the situation that the wooden cover piece 4 is stuck in the second feeding port 42 and affects the assembly speed of the wooden cover piece 4, thereby further improving the assembly efficiency and assembly accuracy; when the electric heating push block 48 presses the wooden cover piece 4 down into the wooden piece installation groove 6, the external controller controls the electric heating push block 48 to heat, and uses the heat generated by the electric heating push block 48 to initially accelerate the solidification of the glue in the wooden piece installation groove 6. After the time is up, the second electric push rod 46 drives the electric heating push block 48 to rise and reset, thereby further shortening the glue solidification time, improving assembly efficiency and reducing labor intensity.

[0049] Furthermore, the second lifting drive member includes a fixed plate 51 and a second longitudinal linear guide rail 50 , the dispensing machine 12 and the top of the mounting plate 39 are connected to one side of the fixed plate 51 , and the slider of the second longitudinal linear guide rail 50 is connected to the other side of the fixed plate 51 .

[0050] From the above description, it can be seen that when it is necessary to start the descending function of the second lifting drive member, the external controller controls the motor of the second longitudinal linear guide 50 to start, and the slider of the second longitudinal linear guide 50 drives the mounting plate 39, the material storage tube 40, the glue dispenser 12, the fixed plate 51, the second discharge pipe 41, the second translation cylinder 43 and the second push rod 44 to descend in the direction close to the fixed seat 8 until they descend to the bottom of the second discharge port 42 at the notch of the wood chip mounting groove 6. When it is necessary to start the ascending function of the second lifting drive member, conversely, the function of automatically driving the glue dispenser 12 and the wood chip discharge device to rise and fall can be realized.

[0051] Furthermore, the discharging device includes a support frame 52, a clamp 53 for grabbing the bottom frame wood strips 1, a clamp cylinder 54 for controlling the opening and closing of the clamp 53, a second lifting cylinder 55 for driving the clamp cylinder 54 to rise and fall, and a transverse linear guide 56 for driving the second lifting cylinder 55 to the next process. The transverse linear guide 56 is installed at the top of the support frame 52, the second lifting cylinder 55 is connected to the slider of the transverse linear guide 56, the top of the clamp cylinder 54 is fixedly connected to the top rod of the second lifting cylinder 55, the two driving ends of the clamp cylinder 54 are fixedly connected to the clamp 53, and both sides of the fixed seat 8 are provided with a clearance groove 57 for the clamp 53 to pass through.

[0052] As can be seen from the above description, when it is necessary to transport the assembled and fixed bottom frame wood strips 1 to the next splicing process, the second lifting cylinder 55 is first started, and the top rod of the second lifting cylinder 55 extends downward, driving the clamping cylinder 54 to move toward the fixed seat 8 until the clamping claw 53 drops to the clearance groove 57, and then the clamping claw cylinder 54 is started, and the two driving ends of the clamping claw cylinder 54 drive the clamping claw 53 to clamp the bottom frame wood strips 1, and then, the top rod of the second lifting cylinder 55 contracts, driving the clamping claw cylinder 54 and the bottom frame wood strips 1 to move. The frame wood strips 1 move upward to reset, and then the motor of the transverse linear guide 56 is started. The slider of the transverse linear guide 56 drives the second lifting cylinder 55 to move away from the turntable 7 toward the next splicing process. When it reaches the next splicing process, the top rod of the second lifting cylinder 55 drives the bottom frame of the clamping cylinder 54 to descend, and finally the driving end of the clamping cylinder 54 opens, and the bottom frame wood strips 1 fall to the next process, which can automatically transport the assembled and fixed bottom frame wood strips 1 to the next process.
