Description

Technical Field

[0001] This invention belongs to the technical field of wood frame manufacturing equipment, and more specifically, it relates to an automatic assembly machine for decorative wood frames. Background Technology

[0002] A rectangular decorative wooden frame is a frame structure made of four wooden strips joined together perpendicularly end to end. It has an internal space for placing items such as photos and tablets, serving to limit and fix the items within the frame, while also functioning as a decorative element. Currently, one existing technology is a type of magnetically attached decorative wooden frame, such as... Figure 1 As shown, it includes three side frame wooden strips 2, one bottom frame wooden strip 1, each equipped with multiple magnet pieces 3 and wooden cover pieces 4. The inner side of the bottom frame wooden strip 1 has a wooden piece mounting groove 6 and a magnet mounting hole 5 communicating with the bottom of the groove 6. The magnet pieces 3 are embedded in the magnet mounting holes 5 to fix a tablet computer or mobile phone inside the frame or to vertically fix it to a magnetically attachable metal platform. The current assembly method of this wooden frame is usually to manually insert the fixing magnets into the magnet mounting holes 5, then apply glue to the upper surface of the magnet piece 3 and the bottom of the groove 6, and then glue the wooden cover piece 4 into the groove 6. A wooden hammer and a wooden mallet are then used to complete the assembly. The block is hammered down to press the wooden cover plate 4 into the wooden plate mounting groove 6, so that the wooden cover plate 4 is tightly bonded to the magnet plate 3 and the groove wall of the wooden plate mounting groove 6. After the glue solidifies, all the wooden strips can be glued and spliced ​​together. However, in the assembly process of the bottom frame wooden strip 1, the whole process relies on manual labor. One hand holds the bottom frame wooden strip 1, and the other hand places the magnet plate 3 and the wooden cover plate 4 in sequence, applies glue manually, and applies force to press the wooden cover plate 4. During this period, it is also necessary to manually check whether the bottom frame wooden strip 1 has holes. It is time-consuming and laborious. Manually hammering down the wooden cover plate 4 is unsafe. Overall, there are problems of low assembly efficiency, high labor intensity and low safety. Summary of the Invention

The electric heating rods are located on the lower pressure plate and are mounted on the fixed disc.

[0011] Further configuration: The wood chip feeding device includes a mounting plate and several storage tubes for vertically stacking individual wood cover pieces. The storage tubes are installed on one side of the mounting plate, and the number of storage tubes is the same as the number of wood chip mounting slots for a single bottom frame wood strip. One side of the bottom of the storage tube is connected to several second discharge tubes for single wood cover pieces to pass through laterally. The bottom of the second discharge tube away from the storage tube has a second discharge port for discharging wood cover pieces and is located directly above the wood chip mounting slot. The second discharge port is the discharge port of the wood chip feeding device. A second translation cylinder is installed on the side of the mounting plate away from the second discharge tube. The top rod of the second translation cylinder is connected to several second push rods for pushing the magnetic pieces to move horizontally from the bottom of the storage tank to the second discharge port. The other side of the bottom of the storage tube has a second clearance hole for the second push rods to pass through. The length of the second push rod is greater than the sum of the length of the second discharge tube and the thickness of the storage tube.

[0012] Further configuration: A second electric push rod is installed on the top of the second discharge pipe. The top rod of the second electric push rod is connected to a second connecting plate. The bottom of the second connecting plate is detachably connected to a number of electrically heated push blocks for pressing the magnet pieces into the magnet mounting holes. The number of the electrically heated push blocks is the same as the number of wood piece mounting slots of a single bottom frame wood strip. A second through hole is opened on the top of the second discharge pipe, which communicates with the second discharge port and allows the electrically heated push blocks and wires to pass through.

[0013] Further configuration: The lifting drive component includes a fixed plate and a second longitudinal linear guide rail.

[0028] To explain the technical content, objectives, and effects of this invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "above" and "below" used in the following description refer to the attached drawings. Figure 4 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 4 The direction towards the geometric center of a specific component.

[0029] The most crucial concept of this invention lies in the following: The turntable 7, the rotary drive, and multiple fixed seats 8 serve to limit and fix multiple bottom frame wooden strips 1 and simultaneously transport them; the hole detection device and alarm automatically detect whether the bottom frame wooden strips 1 to be assembled are qualified; the first infrared sensor 11, the magnet feeding device, and multiple feeding ports of the magnet feeding device automatically detect the presence of bottom frame wooden strips 1 and automatically assemble and place magnet pieces 3 inside the bottom frame wooden strips 1; a set of glue dispensing machines 12 and a lifting drive automatically apply glue to the upper surface of the magnet pieces 3 and the wood chip mounting groove 6; the lifting drive, the translation mechanism 13, the wood chip feeding device, and multiple feeding ports of the wood chip feeding device automatically fix and assemble the wooden cover piece 4 and the magnet piece 3 inside the bottom frame wooden strip 1; the baking device automatically accelerates the curing of the glue; and the discharge device automatically transports the assembled and fixed bottom frame wooden strips 1 to the next process.

[0030] The present invention has a high degree of automation. Compared with assembly line assembly, it occupies a small area. In the subsequent assembly process, there is no need for manual fixing and moving of the bottom frame wooden strip 1. At the same time, it avoids the situation where the detection is prone to errors and visual fatigue caused by manual 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 includes a turntable 7, a rotary drive for rotating the turntable 7, a hole detection device, a magnetic feeding device, a wood chip feeding device, a baking device, and a discharge device arranged sequentially along the rotation direction of the turntable 7. The hole detection device is used to detect whether the bottom frame wood strip 1 has magnetic mounting holes 5 and wood chip mounting grooves 6. Multiple fixing seats 8 are evenly distributed on the turntable 7, and fixing grooves 9 for placing the bottom frame wood strip 1 are opened on the fixing seats 8. An alarm 10 is provided on one side of the hole detection device, and the magnetic feeding device is located near the turntable 7. One side of the device is equipped with a first infrared sensor 11 for detecting whether there is a bottom frame wooden strip 1. The wood chip feeding device is equipped with several feeding ports corresponding to the wood chip mounting slot 6. The magnet feeding device is equipped with a feeding port corresponding to the magnet mounting hole 5. The side of the wood chip feeding device near the turntable 7 is equipped with a set of glue dispensing machines 12 located above the fixed seat 8. Outside the turntable 7, there are also lifting drive components for driving the glue dispensing machine 12, the wood chip feeding device to rise and fall, and a translation mechanism 13 for driving the lifting drive components, the glue dispensing machine 12, and the wood chip feeding device to move towards the fixed seat 8.

[0032] As described above, when it is necessary to assemble and fix the magnet piece 3 and the wooden cover piece 4 into the bottom frame wooden strip 1, firstly, the bottom frame wooden strip 1 to be assembled is placed in the fixing groove 9 on the fixing seat 8 through the turntable 7, the rotary drive, and multiple fixing seats 8. At this time, the wooden piece mounting groove 6 of the bottom frame wooden strip 1 is on top and the magnet mounting hole 5 is on the bottom. The rotary drive is started, which drives multiple bottom frame wooden strips 1 to be assembled to be transported sequentially towards the hole detection device. This serves to limit and fix multiple bottom frame wooden strips 1 and transport multiple bottom frame wooden strips 1 at the same time, avoiding the need for manual fixing and handling of the bottom frame wooden strips 1 in the subsequent assembly process, thereby improving the overall assembly efficiency and reducing labor intensity. Then, when the bottom frame wooden strip 1 to be assembled is transported to the hole detection device, it is detected by the hole detection device and... An alarm is activated by an external controller that activates a hole detection device. This device checks whether the bottom frame wooden strip 1 to be assembled, which has been moved below the device, has magnet mounting holes 5 and wood chip mounting slots 6. If no magnet mounting holes 5 or wood chip mounting slots 6 are detected in the bottom frame wooden strip 1, the external controller activates an alarm. The defective bottom frame wooden strip 1 is then removed by an external robotic arm or manually. The alarm serves to remind workers to re-drill holes in the removed defective bottom frame wooden strip 1 or to recycle it for scrap. This system automatically detects whether the bottom frame wooden strip 1 to be assembled is qualified, avoiding errors and visual fatigue caused by manual observation, which can affect subsequent assembly speed and consume more manpower. This system further improves assembly efficiency and reduces labor intensity.

[0033] Then, via the first infrared sensor 11 and the magnet feeding device, when the first infrared sensor 11 detects that a bottom frame wood strip 1 is being conveyed to the magnet feeding device, the first infrared sensor 11 sends the detected signal to the external controller. The external controller then controls the magnet feeding device to start, using the magnet feeding device to sequentially feed the magnet pieces 3 from the feeding ports of several magnet feeding devices into the magnet mounting holes 5 corresponding to the bottom frame wood strip 1. When the first infrared sensor 11 detects a bottom frame wood strip 1 without a bottom frame, the magnet feeding device and... Subsequently, the glue dispensing machine 12, the first lifting mechanism, and the wood chip unloading device are not activated, serving to automatically detect the presence of the bottom frame wood strip 1 and automatically assemble the magnetic piece 3 inside the bottom frame wood strip 1. Then, when the bottom frame wood strip 1 with the magnetic piece 3 installed rotates with the turntable 7 to the wood chip unloading device station, a set of glue dispensing machine 12, lifting drive, translation mechanism 13, and wood chip unloading device is activated. The lifting drive starts first, driving the glue dispensing machine 12 to descend towards the fixed seat 8 until it reaches the preset height. At this point, the glue dispensing machine 12 is positioned at the wood chip mounting point. A short distance is pre-set above the mounting slot 6. This distance facilitates the application of glue by the dispensing machine 12 onto the wood chip mounting slot 6 and the magnet 3. The dispensing machine 12 is started, and after it has applied glue to the wood chip mounting slot 6 and the magnet 3, the lifting drive unit moves the dispensing machine 12 and the wood chip unloading device upwards and resets. Then, the translation mechanism 13 is activated. The drive end of the translation mechanism 13 moves the dispensing machine 12, the lifting drive unit, and the wood chip unloading device radially along the turntable 7 towards the turntable 7 until the wood chip unloading device is positioned at the desired location. When the fixed seat 8 is above, the lifting drive component descends, driving the wood chip feeding device and the glue dispensing machine 12 to descend until the aforementioned preset height is reached. Then, the external controller controls the wood chip feeding device to start. The wood chip feeding device uses multiple single wood cover pieces 4 to be pressed down and conveyed sequentially from the feeding ports of several wood chip feeding devices to the corresponding wood chip mounting holes. Each wood cover piece 4 is glued to the wood chip mounting hole and the magnetic piece 3 through the glue in the corresponding wood chip mounting hole, which plays the role of automatically fixing and assembling the wood cover piece 4 and the magnetic piece 3 in the bottom frame wood strip 1.

[0034] Next, the bottom frame wood strip 1, assembled with the wooden cover piece 4 and the magnet piece 3, is conveyed to the baking device along with the turntable 7. By starting the baking device, the glue in the magnet mounting hole 5 and the wood piece mounting groove 6 is heated and baked 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 almost completely solidified and will not be dried and evaporated, thus automatically accelerating the solidification of the glue. Finally, the assembled bottom frame wood strip 1 is conveyed to the next splicing process through the discharge device, thus automatically conveying the assembled bottom frame wood strip 1 to the next process.

[0035] Furthermore, the magnet feeding 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 the slider of the first longitudinal linear guide rail 15. The material box 14 has several storage slots 16 for vertically stacking individual magnet pieces 3. The number of storage slots 16 is the same as the number of magnet mounting holes 5 on a single bottom frame wooden strip 1. One side of the bottom of the storage slot 16 is connected to several first discharge pipes 17 for horizontal passage of a single magnet piece 3. The bottom of the first discharge pipe 17 away from the material box 14 has a feeding port for discharging the magnet pieces 3. The first discharge port 18 is located directly above the magnet mounting hole 5. The first discharge port 18 is the discharge port of the magnet feeding device. The material box 14 is equipped 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 several first push rods 21 for pushing the magnet pieces 3 from the bottom of the storage tank 16 to the first discharge port 18. A first clearance hole 22 is opened on the other side of the bottom of the storage tank 16 for the first push rods 21 to pass through. 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] As described above, when the first infrared sensor 11 detects that a bottom frame wood strip 1 is being conveyed to the magnetic feeding device, the first infrared sensor 11 sends the detected signal to an external controller (not shown in the figure, but the same applies throughout the text). The external controller controls the motor of the first longitudinal linear guide 15 to start. 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 together towards the fixed base 8 until they descend to the bottom of the first discharge port 18 and contact the bottom of the wood chip mounting groove 6. Then, the first translation cylinder 19 is activated, and the first push rod 21... The push rod of the shift cylinder 19 extends, driving multiple first push rods 21 to work together. The first push rod 21 pushes a piece of magnet 3 at the bottom of the corresponding storage tank 16 into the first discharge pipe 17 until the piece of magnet 3 is pushed to the first discharge port 18. The first shift cylinder 19 drives the first push rod 21 to reset. Under the action of gravity, the piece of magnet 3 falls into the magnet mounting hole 5 through the first discharge port 18, which automatically and simultaneously assembles each piece of magnet 3 into the corresponding magnet mounting hole 5. Compared with manually placing each piece of magnet 3 into the magnet mounting hole 5 one by one, the assembly efficiency is fast and the assembly accuracy is high.

[0037] Furthermore, the fixing base 8 is detachably connected to the turntable 7, and the bottom of the fixing groove 9 is provided with several sets of positioning magnets 23 for magnetically attracting the magnetic sheet 3. The positioning magnets 23 have opposite magnetic properties to the magnetic sheet 3. Each set of positioning magnets 23 is located below the magnet mounting hole 5 on both sides. The magnetic attraction force of the positioning magnets 23 is less than the material picking force of the discharge device.

[0038] As can be seen from the above description, when the magnet piece 3 is pushed to the first feeding port 18, the first translation cylinder 19 drives the first push rod 21 to reset. Under the action of gravity and the magnetism of the positioning magnet 23, the magnet piece 3 falls through the first feeding port 18 and is attracted into the magnet mounting hole 5, which plays the role of automatically assembling each magnet piece 3 into 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 a first connecting plate 25. The bottom of the first connecting plate 25 is detachably connected to a number 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. The top of the first discharge pipe 17 is provided with a first through hole 27 that communicates with the first discharge port 18 and allows the wooden pressing blocks 26 to pass through.

[0040] As described above, when the magnet piece 3 is pushed to the first feeding port 18, the first electric push rod 24 is activated. The top rod of the first electric push rod 24 extends downward, driving the first connecting plate 25 to move downward. This causes multiple wooden blocks 26 to pass through the first through holes 27 of the corresponding first discharge pipe 17 and enter the first discharge pipe 17. After the wooden blocks 26 enter the first discharge pipe 17, they press the falling magnet piece 3 into the magnet mounting hole 5, ensuring that the magnet piece 3 falls completely into the magnet mounting hole 5 and that the bottom of the magnet piece 3 is tightly fitted with the bottom of the magnet mounting hole 5. This prevents the magnet piece 3 from getting stuck in the first feeding port 18 and affecting the assembly speed of the magnet piece 3. Afterward, the first electric push rod 24 drives the wooden blocks 26 to rise and reset, thus completing the assembly of the magnet piece 3 and further improving the assembly efficiency and accuracy.

[0041] Furthermore, the hole detection device includes a light shield 28, an LED light 29, an industrial camera 30, and a set of second infrared sensors 31 for detecting whether there are magnet mounting holes 5 in the bottom frame wooden strip 1. The LED light 29 is installed at the top center of the light shield 28, and the industrial camera 30 is installed on both sides of the top of the light shield 28. The industrial camera 30 is electrically connected to an industrial control computer. A photoelectric switch 32 for detecting whether there are bottom frame wooden strips 1 in the fixed seat 8 is connected to the side of the light shield 28 away from the magnet feeding device. A fixed disc 33 is provided below the turntable 7. A circular hole is opened in the middle of the fixed disc 33 for the upper end of the rotating drive component to pass through. Both the turntable 7 and the fixed seat 8 are provided with clearance through holes 34 that communicate with the magnet mounting holes 5. The second infrared sensor 31 is installed on the fixed disc 33. A collection box for collecting waste glue is detachably installed at the bottom of the fixed disc 33.

[0042] As described above, when the bottom frame wood strip 1 to be assembled is about to be conveyed to the hole detection device, the photoelectric switch 32 detects the presence of the bottom frame wood strip 1 and sends a signal to the external controller. The external controller then controls the second infrared sensor 31 and the industrial camera 30 to start. The industrial camera 30 collects image information of the bottom frame wood strip 1 and sends the captured image information to the industrial control computer. The industrial control computer first compares and classifies the image with preset images to determine whether there is a wood chip mounting slot 6. The second infrared sensor 31 detects whether there is an obstruction above the clearance through hole 34 and whether the infrared light emitted by the second infrared sensor 31 is completely blocked. That is, if there is no magnet mounting hole 5, then an obstruction is detected above the clearance through hole 34. This system enables automatic detection of whether the bottom frame wooden strip 1 has magnet mounting holes 5 and wood chip mounting slots 6. A fixed disc 33, which does not rotate with the turntable 7, facilitates the installation of the second infrared sensor 31. A detachable collection box collects any residual waste glue that flows from the magnet mounting holes 5 during glue application, avoiding the need for manual cleaning and further reducing labor intensity. A light shield 28 and LED lights 29 illuminate the bottom frame wooden strip 1 while simultaneously blocking light on one side, preventing changes in external light from affecting the accuracy of image recognition of the bottom frame wooden strip 1 and further improving the accuracy of hole detection.

[0043] Furthermore, the baking device includes a support 35, a first lifting cylinder 36, and multiple electric heating rods 37 for accelerating the curing of glue on the magnet sheet 3. The first lifting cylinder 36 is mounted on the support 35, and 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 mounted on a fixed disc 33.

[0044] As described above, when the bottom frame wood strip 1, which is assembled with the wooden cover 4 and the magnet 3, is transported to the baking device by the turntable 7, the external controller first controls the top rod of the first lifting cylinder 36 to extend downward, driving the lower pressure plate 38 to press the wooden cover 4 further downward, so that the bottom of the wooden cover 4 is in close contact with the glue. Then, the electric heating rod 37 is activated, and the heat generated by the electric heating rod 37 enters the magnet mounting hole 5 through the clearance through hole 34. The heat is used to bake and heat the glue in the magnet mounting hole 5 and the wood chip mounting groove 6, accelerating the solidification of the glue. When the preset time is reached, the glue is almost completely solidified, but it will not be dried and evaporated. The residual heat of the electric heating rod can be used to continue heating the glue, which plays the role of automatically accelerating the solidification of the glue.

[0045] Furthermore, the wood chip feeding device includes a mounting plate 39 and several storage pipes 40 for vertically stacking individual wood cover pieces 4. The storage pipes 40 are detachably installed on one side of the mounting plate 39. The number of storage pipes 40 is the same as the number of wood chip mounting slots 6 of a single bottom frame wood strip 1. The bottom side of the storage pipe 40 is connected to several second discharge pipes 41 for horizontal passage of a single wood cover piece 4. The bottom of the second discharge pipe 41 away from the storage pipe 40 has a second discharge pipe 41 for discharging wood cover pieces 4 and is located directly above the wood chip mounting slot 6. The material inlet 42 is the material outlet of the wood chip feeding device. A second translation cylinder 43 is installed on the side of the mounting plate 39 away from the second discharge pipe 41. The top rod of the second translation cylinder 43 is connected to several second push rods 44 for pushing the magnet 3 from the bottom of the storage tank 16 to the second material inlet 42. A second clearance hole 45 is opened on the other side of the bottom of the storage pipe 40 for the second push rod 44 to pass through. 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] As described above, when the bottom frame wood strip 1 with the magnet 3 is conveyed to the wood chip feeding device, the glue dispensing machine 12 completes the glue application, and the drive end of the translation mechanism 13 moves the wood chip feeding device above the corresponding fixed seat 8, the lifting drive component descends, causing the wood chip feeding device and the glue dispensing machine 12 to descend until the bottom of the second feeding port 42 is located at the slot of the wood chip mounting groove 6. At this point, the external controller controls the second translation cylinder 43 to start, and the push rod of the second translation cylinder 43 extends, driving multiple... The two push rods 44 work together. The second push rod 44 pushes a piece of wood cover 4 at the bottom of the corresponding storage tube 40 into the second discharge tube 41 until the piece of wood cover 4 is pushed to the second discharge port 42. Under the action of gravity, the piece of wood cover 4 falls into the wood cover 4 installation slot through the second discharge port 42, which automatically and simultaneously assembles multiple single pieces of wood cover 4 into the corresponding magnet installation holes 5. Compared with manually placing the pieces of wood cover 4 into the wood piece installation slots 6 one by one, the assembly efficiency is fast and the assembly accuracy is high.

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

[0048] As described above, when the wooden cover 4 is pushed to the second discharge port 42, the second electric push rod 46 is activated. The top rod of the second electric push rod 46 extends downward, driving the second connecting plate 47 to move downward. This causes multiple electrically heated push blocks 48 to pass through the second through holes 49 of the corresponding second discharge pipe 41 and enter the second discharge pipe 41. After the electrically heated push blocks 48 enter the second discharge pipe 41, they press the falling wooden cover 4 into the wooden chip mounting groove 6, ensuring that the wooden cover 4 falls completely into the wooden chip mounting groove 6 and that the bottom of the wooden cover 4 is tightly fitted with the bottom of the wooden chip mounting groove 6. This avoids the situation where the wooden cover 4 gets stuck in the second feeding port 42, which would affect the assembly speed of the wooden cover 4, and further improves the assembly efficiency and accuracy. When the electric heating push block 48 presses the wooden cover 4 down into the wooden chip mounting groove 6, the external controller controls the electric heating push block 48 to heat up. The heat generated by the electric heating push block 48 initially accelerates the solidification of the glue in the wooden chip mounting groove 6. After the time is up, the second electric push rod 46 drives the electric heating push block 48 to rise and reset, which further shortens the glue solidification time, improves the assembly efficiency and reduces the labor intensity.

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

[0050] As can be seen from the above description, when the lowering function of the lifting drive needs to be activated, the external controller controls the motor of the second longitudinal linear guide 50 to start. The slider of the second longitudinal linear guide 50 drives the mounting plate 39, the storage pipe 40, the dispensing machine 12, the fixing plate 51, the second discharge pipe 41, the second translation cylinder 43, and the second push rod 44 to descend together towards the fixed seat 8 until the bottom of the second discharge port 42 is located at the groove of the wood chip mounting slot 6. When the lifting function of the lifting drive needs to be activated, the opposite is true, so that the automatic lifting of the dispensing machine 12 and the wood chip feeding device can be achieved.

[0051] Furthermore, the discharge device includes a support frame 52, a gripper 53 for gripping the bottom frame wooden strip 1, a gripper cylinder 54 for controlling the opening and closing of the gripper 53, a second lifting cylinder 55 for driving the gripper cylinder 54 to rise and fall, and a transverse linear guide rail 56 for driving the second lifting cylinder 55 to the next process. The transverse linear guide rail 56 is installed on the top of the support frame 52. The second lifting cylinder 55 is connected to the slider of the transverse linear guide rail 56. The top of the gripper cylinder 54 is fixedly connected to the top rod of the second lifting cylinder 55. The two driving ends of the gripper cylinder 54 are fixedly connected to the gripper 53. The fixed base 8 has clearance slots 57 on both sides for the gripper 53 to pass through.

[0052] As described above, when the assembled and fixed bottom frame wooden strip 1 needs to be transported to the next splicing process, the second lifting cylinder 55 is first activated. The top rod of the second lifting cylinder 55 extends downward, driving the gripper cylinder 54 to move towards the fixed seat 8 until the gripper 53 descends to the clearance slot 57. Then, the gripper cylinder 54 is activated again, and the two drive ends of the gripper cylinder 54 drive the gripper 53 to clamp the bottom frame wooden strip 1. Then, the top rod of the second lifting cylinder 55 retracts, driving the gripper cylinder 54 and the bottom frame... After the frame wood strip 1 moves upward and resets, the motor of the horizontal linear guide rail 56 is started. The slider of the horizontal linear guide rail 56 drives the second lifting cylinder 55 to move away from the turntable 7 towards 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 gripper cylinder 54 to descend. Finally, the drive end of the gripper cylinder 54 opens, and the bottom frame wood strip 1 falls to the next process, which can automatically transport the assembled and fixed bottom frame wood strip 1 to the next process.
