Description

Technical Field

[0001] This invention relates to the field of sawing and drilling machines, specifically to a fully automatic 45-degree sawing and drilling machine for wood processing. Background Technology

[0002] In wood panel processing, 45-degree angle sawing and drilling are core foundational processes in furniture manufacturing, door and window processing, and decorative panel splicing. Their processing precision and efficiency directly determine the sealing performance, structural stability, and appearance regularity of the finished product. This is especially true in high-end panel processing scenarios such as custom furniture and solid wood doors and windows, where the requirements for 45-degree sawing angle precision, drilling position precision, and process continuity are even more stringent. The fully automatic 45-degree saw and drill machine, as a key piece of equipment for this type of processing, can complete the integrated operation of 45-degree sawing and drilling of wood panels, and is a core piece of equipment driving the upgrading of wood panel processing towards large-scale, refined, and automated production.

[0003] In response to this, this application designs a fully automatic 45-degree saw and drill machine for wood board processing. Most existing wood board saw and drill processing equipment adopts semi-automatic control or step-by-step processing structure, which requires sawing and drilling processes in sequence. For wood boards that require high-precision splicing, this type of processing method will lead to fluctuations in processing accuracy. It is difficult to accurately control the position and coaxiality of the drilling position and the sawing bevel, resulting in defects such as hole position offset and rough hole wall. It cannot meet the processing requirements of high-end boards, and the consistency of batch processing needs to be improved. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a fully automatic 45-degree sawing and drilling machine for wood processing. This effectively solves the problem that existing sawing and drilling equipment requires sequential sawing and drilling processes. For wood boards requiring high-precision splicing, this processing method leads to fluctuations in processing accuracy, difficulty in accurately controlling the position and coaxiality of the drilling hole relative to the sawing bevel, and defects such as hole position misalignment and rough hole walls. This fails to meet the requirements of high-end board processing, and the consistency of batch processing needs to be improved.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a fully automatic 45-degree saw and drill machine for wood processing, comprising:

[0007] The frame has negative pressure suction plates symmetrically installed at the front and back of the upper end, auxiliary support plates symmetrically installed at the front and back of the frame, a storage rack installed on the left side of the upper end of the frame, an installation frame installed in the middle of the upper end of the frame, and a slide rail installed on the inner wall of the bottom end of the frame. Several rollers evenly distributed from left to right are installed through the two negative pressure suction plates on the right side, and a conveyor belt is sleeved on the outer wall of the rollers. The slide rail is equipped with a clamping and positioning part for clamping the wooden board and driving it to be intermittently conveyed to the right. The adjacent negative pressure suction plates and auxiliary support plates are equipped with a sawing part for sawing and drilling the wooden board at a 45-degree angle.

[0008] The sawing section includes a material discharge port in the middle of the upper part of the negative pressure suction plate. The material discharge port is composed of a trapezoidal clearance groove and a rectangular through hole. A mounting base is installed on the upper part of the auxiliary support plate corresponding to the material discharge port. The sawing assembly is set on both the negative pressure suction plate and the mounting base.

[0009] Furthermore, the clamping and positioning part includes an electric slide block that is slidably mounted on the slide rail. An extension frame is mounted on the upper end of the electric slide block via a support plate. Electric push rods are symmetrically installed through the upper end of the support plate. The telescopic ends of the two electric push rods slide through the extension frame and are jointly mounted on a bearing platform connected to the extension frame via a buffer spring. Several clamping groups are evenly distributed from left to right on the bearing platform, and a push plate is also installed on the right side of the upper end of the bearing platform.

[0010] Furthermore, the sawing assembly includes an auxiliary support plate and a pneumatic push rod 1 that is symmetrically installed in the same direction on the mounting base. The telescopic ends of the two pneumatic push rods 1 are jointly equipped with an outer protective plate. The outer protective plate has a U-shaped structure, and the end of the outer protective plate facing the negative pressure suction plate is equipped with an electric saw housing through a connecting plate. The saw blade is rotatably installed on the inner wall of the electric saw housing, and an intermittent motor for driving the rotation of the saw blade is installed on the inner wall of the outer protective plate.

[0011] Furthermore, the sawing assembly also includes a receiving cavity opened at the upper end of the mounting base. A dual-axis drill bit body is installed on the inner wall of the receiving cavity. The dual-axis drill bit body consists of a spindle box and a drill bit. A servo motor for driving the dual-axis drill bit body is installed at the upper end of the auxiliary support plate via a motor mount.

[0012] Furthermore, the clamping assembly includes a positioning plate mounted on the upper part of the support platform, a cylinder mounted on the upper part of the support platform to the right of the positioning plate, a clamping plate fixedly connected to the telescopic end of the cylinder, and a slidably connected lower end of the clamping plate to the support platform.

[0013] Furthermore, the upper end of the negative pressure suction plate is symmetrically pre-opened with several air holes evenly distributed from left to right. A spring plunger is installed on the inner wall of the bottom end of the air hole. The diameter of the spring plunger is smaller than the diameter of the air hole, and the spring plunger is composed of a hollow shell, a compression spring and a steel ball.

[0014] Furthermore, a guide plate is installed on the inner wall of the discharge port at the end away from the bearing platform, and a chip removal cover plate fixedly connected to the frame is installed at the lower end of the negative pressure suction plate corresponding to the discharge port.

[0015] Furthermore, an inlet is provided on the upper left side of the storage rack, and an outlet is provided on the lower right side of the storage rack corresponding to the positioning plate. Several ball bearings are symmetrically embedded on the inner walls of the front and rear ends of the storage rack, and are evenly distributed from top to bottom.

[0016] Furthermore, pneumatic push rods two are symmetrically installed through the upper end of the mounting frame, and a pressure head is installed at the telescopic end of the pneumatic push rods two.

[0017] Furthermore, a limit stop is installed on the upper end of the auxiliary support plate corresponding to the discharge port on the storage rack.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention provides a fully automatic 45-degree sawing and drilling machine for wood processing. After the wood is sawn at a certain angle, two pneumatic push rods are controlled to work synchronously to return to their original positions. Then, a servo motor drives the spindle box of the dual-axis drill body, thereby controlling the two corresponding drill bits to rotate synchronously at high speed and feed at a constant speed towards the sawn bevel of the wood until the dual-axis drill body synchronously completes the drilling of the wood. Then, the two corresponding drill bits are controlled to rotate synchronously in opposite directions at high speed and withdraw at a constant speed from the drilled holes in the wood to return to their original positions. Finally, the servo motor stops working. By using a synchronous sawing and drilling method, the drilling position is precise, and the position and coaxiality with the saw bevel are controllable, solving the defects such as hole position offset and rough hole wall caused by the step-by-step processing of existing equipment. The mounting base is installed corresponding to the material drop port, which can ensure that the processing position of the dual-axis drill body and the saw blade are aligned, realizing synchronous linkage of sawing and drilling, eliminating the need for step-by-step operation and improving processing efficiency.

[0030] The present invention will be further described below with reference to embodiments.

[0031] Example:

[0032] Please see Figures 1-7 This invention provides a technical solution: a fully automatic 45-degree saw and drill machine for wood processing, comprising:

[0033] The frame 1 has negative pressure suction plates 2 symmetrically installed at the front and back of the upper end of the frame 1, auxiliary support plates 3 symmetrically installed at the front and back of the frame 1, a storage rack 4 installed on the left side of the upper end of the frame 1, an installation rack 5 installed in the middle of the upper end of the frame 1, and a slide rail 6 installed on the inner wall of the bottom end of the frame 1. Several rollers evenly distributed from left to right are installed through the two negative pressure suction plates 2 on the right side and rotate together. A conveyor belt 7 is sleeved on the outer wall of the rollers. A clamping and positioning part 8 is provided on the slide rail 6 for clamping the wooden board and driving it to be intermittently conveyed to the right. A sawing part 9 for sawing and drilling the wooden board at a 45-degree angle is provided on the adjacent negative pressure suction plates 2 and auxiliary support plates 3.

[0034] The sawing section 9 includes a material discharge port 92 opened at the middle of the upper end of the negative pressure suction plate 2. The material discharge port 92 is composed of a trapezoidal clearance groove and a rectangular through hole. The upper end of the auxiliary support plate 3 is equipped with a mounting base 93 corresponding to the material discharge port 92. The negative pressure suction plate 2 and the mounting base 93 are jointly provided with a sawing assembly 94.

[0035] The clamping and positioning part 8 includes an electric slide block 81 that is slidably mounted on the slide rail 6. An extension frame 82 is mounted on the upper end of the electric slide block 81 via a support plate. Electric push rods 83 are symmetrically mounted through the upper end of the support plate. The telescopic ends of the two electric push rods 83 slide through the extension frame 82 and are jointly mounted on a bearing platform 84 connected to the extension frame 82 via a buffer spring. Several clamping groups 85 are evenly distributed from left to right on the bearing platform 84, and a push plate is also mounted on the upper right side of the bearing platform 84.

[0036] The sawing assembly 94 includes an auxiliary support plate 3 and a pneumatic push rod 941 symmetrically installed at a 45-degree angle on the mounting base 93. The telescopic ends of the two pneumatic push rods 941 are jointly equipped with an outer protective plate 942. The outer protective plate 942 has a U-shaped structure, and the end of the outer protective plate 942 facing the negative pressure suction plate 2 is equipped with a saw housing through a connecting plate. A saw blade 944 is rotatably installed on the inner wall of the saw housing. An intermittent motor 943 for driving the saw blade 944 to rotate is installed on the inner wall of the outer protective plate 942.

[0037] The sawing assembly 94 also includes a receiving cavity opened at the upper end of the mounting base 93. A dual-axis drill bit body 945 is installed on the inner wall of the receiving cavity. The dual-axis drill bit body 945 consists of a spindle box and a drill bit. A servo motor 946 for driving the dual-axis drill bit body 945 is installed at the upper end of the auxiliary support plate 3 through a motor mount.

[0038] The clamping assembly 85 includes a positioning plate 851 mounted on the upper end of the bearing platform 84. A cylinder 852 is mounted on the upper end of the bearing platform 84 to the right of the positioning plate 851. A clamping plate 853 is fixedly connected to the telescopic end of the cylinder 852. The lower end of the clamping plate 853 is slidably connected to the bearing platform 84.

[0039] The upper end of the negative pressure suction plate 2 is symmetrically pre-opened with several air holes evenly distributed from left to right. A spring plunger 21 is installed on the inner wall of the bottom end of the air hole. The diameter of the spring plunger 21 is smaller than the diameter of the air hole, and the spring plunger 21 is composed of a hollow shell, a compression spring and a steel ball.

[0040] A guide plate 921 is installed on the inner wall of the discharge port 92 at the end away from the bearing platform 84, and a chip discharge cover plate 922 is installed at the lower end of the negative pressure suction plate 2 corresponding to the discharge port 92 and fixedly connected to the frame 1.

[0041] The storage rack 4 has an inlet on the upper left side and an outlet on the lower right side corresponding to the positioning plate 851. Several ball bearings 41 are symmetrically embedded on the inner walls of the front and rear ends of the storage rack 4 and are evenly distributed from top to bottom.

[0042] The upper end of the mounting bracket 5 is symmetrically equipped with pneumatic push rods 51, and the telescopic end of the pneumatic push rods 51 is equipped with a pressing head 52.

[0043] A limit stop bar 71 is installed on the upper end of the auxiliary support plate 3 corresponding to the discharge port on the storage rack 4.

[0044] In practice:

[0045] First, the storage rack 4 in this application is used to pre-store several wooden boards, which slide down to the bottom along the inner wall of the storage rack 4 under their own gravity. The clamping and positioning part 8 is used to accurately clamp several wooden boards and drive them to be synchronously and intermittently conveyed to the right. The sawing part 9 is used to perform 45-degree sawing and drilling on the wooden boards. The conveyor belt 7 is used to continue to convey the wooden boards that have been sawed and drilled at 45 degrees to the right, so as to avoid the accumulation of wooden boards affecting the processing environment. The diameter of the air hole on the negative pressure suction plate 2 is larger than the diameter of the spring plunger 21, so as to retain the original airflow effect. Both the front and rear negative pressure suction plates 2 are connected to the external air pump through air pipes. The external air pump can control the generation of negative pressure adsorption effect in several air holes on the front and rear negative pressure suction plates 2, or release the negative pressure adsorption effect.

[0046] In the initial feeding stage, the operator first puts the batch of wooden boards to be processed into the feed port at the left end of the storage rack 4 and pushes the wooden boards downward to stack them at the bottom of the storage rack 4. At this time, the bottom wooden board will be tightly attached to the upper surface of the two negative pressure suction plates 2 under the combined gravity of the upper wooden boards. The steel column on the corresponding spring plunger 21 will be squeezed back. During this process, the design of several ball bearings 41 can convert the sliding friction between the wooden board and the inner wall of the storage rack 4 into rolling friction, which greatly reduces the friction when the wooden board is lowered, avoids scratching the surface of the wooden board, and facilitates the smooth fall of the wooden board.

[0047] During the wooden board clamping and positioning stage, after several wooden boards are stacked at the bottom of the storage rack 4, the two electric push rods 83 on the left and right work synchronously. The telescopic ends of the two electric push rods 83 will jointly drive the bearing platform 84 to move upward until the upper surface of the bearing platform 84 is in contact with the lower surface of the bottommost wooden board, and the bottommost wooden board is lifted upward by a suitable distance, so that its lower surface is separated from the upper surface of the negative pressure suction plate 2, leaving enough space for the corresponding steel column to be smoothly ejected under the action of the compression spring. At this time, the processing surface of the bottommost wooden board will be in contact with the clamping group 85, the sawing group 94, and the dual-axis drill bit. With the processing height of the main body 945 adapted, the lowest wooden board inside the storage rack 4 will be located between the corresponding positioning plate 851 and clamping plate 853. Since the discharge port on the lower right side of the storage rack 4 corresponds to the positioning plate 851 on the bearing platform 84, the cylinder 852 in each clamping group 85 is then controlled to work. The telescopic end of the cylinder 852 will push the clamping plate 853 to slide along the bearing platform 84 toward the corresponding positioning plate 851 until the clamping plate 853 and the positioning plate 851 are clamped together on the front and rear end faces of the corresponding wooden board, limiting the wooden board in the left and right directions to prevent its position from shifting.

[0048] During the intermittent rightward conveying phase of the wooden plank, once the plank is clamped, the electric slide block 81 can be controlled to slide a suitable distance to the right along the slide rail 6. The electric slide block 81 will drive the riser frame 82, the support platform 84, and the clamped plank to move synchronously to the right a suitable distance, thereby achieving the effect of intermittently conveying the plank to the right. It should be noted that whenever the electric slide block 81 slides a suitable distance to the right along the slide rail 6 and stops moving, the external air pump simultaneously controls several air holes on the front and rear negative pressure suction plates 2 to generate a negative pressure adsorption effect. At this time, several air holes on the lower side of the plank will generate a negative pressure adsorption force on it. Then, the two electric push rods 83 on the left and right are controlled to work together to control the board. The support platform 84 is moved downwards a suitable distance until the upper surface of the support platform 84 is flush with the upper surface of the negative pressure suction plate 2. At this time, the lower surface of the wooden board will be tightly attached to the upper surface of the negative pressure suction plate 2. Then, the cylinder 852 in each clamping group 85 is closed. The telescopic end of the cylinder 852 will drive the clamping plate 853 to slide along the side of the support platform 84 away from the corresponding positioning plate 851 until the clamping plate 853 is away from the wooden board and the positioning plate 851, releasing the left and right limiting clamping effect on the wooden board. At this time, the wooden board will be tightly attached to the upper surface of the negative pressure suction plate 2 under the action of the negative pressure adsorption effect of the corresponding air holes, and the position will be stable and unable to shift.

[0049] After the wooden board is firmly attached to the negative pressure suction plate 2, the two electric push rods 83 are controlled to move the bearing platform 84 downward a suitable distance until the upper surfaces of the positioning plate 851 and the clamping plate 853 are far below the upper surface driven by the negative pressure suction plate 2. At this time, the bearing platform 84 and several clamping groups 85 will move away from the wooden board. Then, the electric slide block 81 is controlled to slide a suitable distance to the left along the slide rail 6 to return to its original position. The electric slide block 81 will drive the lifting frame 82, the bearing platform 84, and the clamped wooden board to move a suitable distance to the left to return to their original position. Then, the operation steps of the wooden board clamping and positioning stage are repeated. The two electric push rods 83 are controlled to work synchronously. The telescopic ends of the two electric push rods 83 will drive the bearing platform 84 to move upward until the upper surface of the bearing platform 84 is attached to the lower surface of the bottommost wooden board, and the bottommost wooden board is lifted upward a suitable distance. At this time, the bottommost wooden board in the storage rack 4 will be positioned. Between the corresponding positioning plate 851 and clamping plate 853, the cylinder 852 in each clamping group 85 is controlled again. The telescopic end of the cylinder 852 will push the clamping plate 853 to slide along the bearing platform 84 toward the corresponding positioning plate 851 until the clamping plate 853 and the positioning plate 851 clamp the front and rear end faces of the corresponding wooden board. The wooden board is clamped in the left and right directions. By repeating this operation, the wooden boards stacked in the storage rack 4 can be conveyed from bottom to top and intermittently to the right. The intermittent sliding design of left and right reciprocating is adopted. After each wooden board is moved an appropriate distance to the preset processing position, it stops and can be sawed and drilled. Then it continues to slide to the right to ensure that the processing process and the conveying action are connected in an orderly manner. At the same time, it can also ensure that only one wooden board falls from the discharge port onto the bearing platform 84 at a time, realizing orderly feeding and avoiding processing chaos caused by feeding multiple wooden boards at the same time.

[0050] It is worth emphasizing that the spring plunger 21 is composed of a hollow shell, a compression spring and steel balls. During the sliding of the wooden board on the negative pressure suction plate 2, the steel balls on the spring plunger 21 will roll and contact the bottom of the wooden board, which not only plays an auxiliary support role, but also reduces the sliding friction between the wooden board and the negative pressure suction plate 2, avoiding the problem of wear and scratches caused by direct sliding contact between the bottom of the wooden board and the negative pressure suction plate 2.

[0051] During the 45-degree sawing and synchronous drilling stage, after the wood board is conveyed to the preset processing position, the upper surface of the bearing platform 84 needs to be kept flush with the upper surface of the negative pressure suction plate 2 until the sawing and drilling of the wood board are completed. Then, the subsequent intermittent conveying steps of the wood board will continue. Specifically, at this time, the wood board will be clamped by the corresponding positioning plate 851 and clamping plate 853, and at the same time, it will be suctioned by the corresponding air holes on the front and rear negative pressure suction plates 2 to ensure that the position of the wood board is stable. Then, the front and rear pneumatic push rods 51 need to be controlled to work simultaneously. The extension end of the pneumatic push rod 51 will drive the pressure head 52 to move downward until the lower surface of the pressure head 52 is tightly pressed against the upper surface of the wood board. This achieves secondary pressing and positioning during the subsequent sawing and drilling of the wood board, avoiding the wood board from jumping up and down and shifting in position during sawing and drilling, and further improving the processing accuracy of sawing and drilling.

[0052] After the lower ends of the two pressure heads 52 are tightly pressed against the upper end of the wooden board, the intermittent motor 943 is first controlled to start working. The intermittent motor 943 will drive the saw blade 944 to rotate at high speed. Then, the two pneumatic push rods 941 are controlled to work synchronously. The two pneumatic push rods 941 will jointly drive the outer protective plate 942 to move downward until the lower end of the outer protective plate 942 is tightly attached to the upper end of the mounting base 93 and the dual-axis drill bit body 945. During this period, the outer protective plate 942 will drive the intermittent motor 943 to move downward synchronously. At the same time, the outer protective plate 942 will also drive the electric saw housing and the saw blade 944 to move downward synchronously through the connecting plate. As the saw blade 944 moves downward... The saw blade 944 gradually approaches the wooden board at a 45-degree angle and performs a 45-degree sawing process until it completely removes the waste material from both ends of the board. The sawing angle is precise and adaptable to the splicing requirements of the wooden boards. The discharge port 92 can avoid the saw blade 944 from colliding with the negative pressure suction plate 2. At the same time, under the guidance of the discharge port 92 and the guide plate 921, the waste material and the generated wood chips will fall onto the corresponding chip discharge cover 922 and continue to be guided and discharged to the lower side by the chip discharge cover 922. Finally, the external receiving device will collect the wood chips in a unified manner, realizing the centralized collection of wood chips, which is convenient for subsequent cleaning and keeps the processing environment clean.

[0053] After the 45-degree sawing of the wood board is completed, the two pneumatic push rods 941 are controlled to work synchronously again. The two pneumatic push rods 941 will jointly drive the outer protective plate 942 to move upward and return to its original position. During this process, the outer protective plate 942 will drive the intermittent motor 943 to move upward and return to its original position synchronously. At the same time, the outer protective plate 942 will also drive the electric saw housing and saw blade 944 to move upward and return to their original positions synchronously through the connecting plate. Then, the servo motor 946 is controlled to drive the spindle box of the dual-axis drill bit body 945, thereby controlling the two corresponding drill bits to rotate synchronously at high speed and feed at a uniform speed towards the processing slope of the wood board after sawing, until the dual-axis drill bit body 945 synchronously completes the drilling of the wood board. Then, the two corresponding drill bits are controlled to rotate synchronously in opposite directions at high speed and... The saw blade is withdrawn from the drilled hole in the wooden board at a uniform speed and returned to its original position. Finally, the servo motor 946 is stopped. The 45-degree sawing and drilling are carried out simultaneously, ensuring precise drilling position and controllable position and coaxiality with the sawing bevel. This solves the defects of existing equipment, such as hole position offset and rough hole wall caused by step-by-step processing. The mounting base 93 is installed corresponding to the material drop port 92, which ensures that the processing position of the dual-axis drill body 945 and the saw blade 944 corresponds, realizing synchronous linkage of sawing and drilling without step-by-step operation, thus improving processing efficiency. It should be noted that the wood chips generated during drilling will also fall onto the corresponding chip removal cover 922 and continue to be guided and discharged to the lower side by the chip removal cover 922, where they are collected by the external receiving device.

[0054] In the processing completion and cycle processing stage, after the processing of a single wood board is completed, the next processing cycle is started simultaneously to achieve fully automatic batch processing. The specific operation is as follows: After sawing and drilling are completed, the electric slide 81 is controlled to intermittently slide back and forth to continuously transport the wood boards in the left storage rack 4 to the right. The processed wood boards will stay on the negative pressure suction plate 2. Whenever the upper end of the bearing platform 84 is flush with the upper end of the negative pressure suction plate 2 and continues to move to the right, the push plate on the upper right side of the bearing platform 84 will push the processed wood board to continue moving to the right until it is pushed onto the conveyor belt 7. It should be noted that the rollers are driven by an external motor to rotate, and several rollers will drive the conveyor belt 7 to move synchronously, thereby enabling the limit stop 71 to drive the processed wood boards to continue to be transported to the right, completing the unloading of the processed wood boards. Repeating the above operation can realize fully automatic batch sawing and drilling of wood boards, while ensuring the consistency of batch processing and meeting the processing requirements of high-end boards.

[0055] In summary, this application has the following advantages:

[0056] Firstly, during the initial feeding stage, the operator puts the wooden boards to be processed into the inlet on the left side of the storage rack 4 in batches and pushes the boards downwards to stack them at the bottom of the storage rack 4. During this process, the design of several ball bearings 41 can convert the sliding friction between the wooden boards and the inner wall of the storage rack 4 into rolling friction, which greatly reduces the friction when the wooden boards are lowered, avoids scratching the surface of the wooden boards, and facilitates the smooth falling of the wooden boards.

[0057] Secondly, during the intermittent rightward conveying phase of the wooden board, once the board is clamped, the electric slide block 81 can be controlled to slide a suitable distance to the right along the slide rail 6, thereby achieving the effect of intermittently conveying the wooden board to the right. Whenever the electric slide block 81 slides a suitable distance to the right along the slide rail 6 and stops moving, the external air pump simultaneously controls several air holes on the front and rear negative pressure suction plates 2 to generate a negative pressure adsorption effect. Then, the left and right electric push rods 83 are controlled to jointly control the bearing platform 84 to move downward a suitable distance until the upper end surface of the bearing platform 84 is flush with the upper end surface of the negative pressure suction plate 2. At this time, the lower end surface of the wooden board will be tightly attached to the upper end surface of the negative pressure suction plate 2. Then, the cylinders 852 in each clamping group 85 are controlled to close until the clamping plate 853 moves away from the wooden board and the positioning plate 851, releasing the left and right direction limiting clamping effect on the wooden board. At this time, the wooden board will be tightly adsorbed on the upper end surface of the negative pressure suction plate 2 under the action of the negative pressure adsorption effect of the corresponding air holes, and the position is stable and cannot be shifted.

[0058] Thirdly, after the wooden board is firmly attached to the negative pressure suction plate 2, the two electric push rods 83 on the left and right are controlled to move the bearing platform 84 downward a suitable distance until the upper surfaces of the positioning plate 851 and the clamping plate 853 are far below the upper surface driven by the negative pressure suction plate 2. Then, the electric slide 81 is controlled to slide a suitable distance to the left along the slide rail 6 to return to its original position. The electric slide 81 will drive the raising frame 82, the bearing platform 84, and the clamped wooden board to move a suitable distance to the left to return to their original position. Then, the operation steps of the wooden board clamping and positioning stage are repeated until the clamping plate 853 and the positioning plate 851 are clamped together. On the front and rear ends of the corresponding wooden board, the wooden board is clamped in the left and right directions. By repeating this operation, the wooden boards stacked in the storage rack 4 can be conveyed from bottom to top and intermittently to the right. The intermittent sliding design with left and right reciprocating means that the wooden board is moved to the preset processing position and then stopped. The wooden board can then be sawed or drilled. Then it continues to slide to the right, ensuring that the processing steps and the conveying action are connected in an orderly manner. At the same time, it can also ensure that only one wooden board falls from the discharge port onto the bearing platform 84 at a time, realizing orderly feeding and avoiding the processing chaos caused by feeding multiple wooden boards at the same time.

[0059] Fourthly, it is worth emphasizing that during the sliding of the wooden board on the negative pressure suction plate 2, the steel ball on the spring plunger 21 will roll into contact with the bottom of the wooden board, which not only provides auxiliary support but also reduces the sliding friction between the wooden board and the negative pressure suction plate 2, thus avoiding the problem of wear and scratches caused by direct sliding contact between the bottom of the wooden board and the negative pressure suction plate 2.

[0060] Fifthly, during the 45-degree sawing and simultaneous drilling stage, after the wood board is conveyed to the preset processing position, it will be clamped by the corresponding positioning plate 851 and clamping plate 853. At the same time, it will be suctioned by the corresponding air holes on the front and rear negative pressure suction plates 2 to ensure the stability of the wood board. Then, the front and rear pneumatic push rods 51 will be controlled to work simultaneously. The extension end of the pneumatic push rod 51 will drive the pressure head 52 to move downward until the lower end face of the pressure head 52 is tightly pressed against the upper end face of the wood board. This achieves secondary pressing and positioning during the subsequent sawing and drilling of the wood board, avoiding the wood board from jumping up and down and shifting in position during sawing and drilling, and further improving the processing accuracy of sawing and drilling.

[0061] Advantage six: After the 45-degree sawing of the wood board is completed, the two pneumatic push rods 941 are controlled to work synchronously to return to their original positions. Then, the servo motor 946 is controlled to drive the spindle box of the dual-axis drill body 945, thereby controlling the two corresponding drills to rotate synchronously at high speed and feed at a constant speed towards the sawn bevel of the wood board until the dual-axis drill body 945 synchronously completes the drilling of the wood board. Then, the two corresponding drills are controlled to rotate synchronously in opposite directions at high speed and withdraw at a constant speed from the drilled holes in the wood board to return to their original positions. Finally, the servo motor 946 is controlled to stop working. By using the method of simultaneous 45-degree sawing and drilling, the drilling position is accurate, and the position and coaxiality with the saw bevel are controllable, solving the defects such as hole position offset and rough hole wall caused by the step-by-step processing of existing equipment. The mounting base 93 is installed corresponding to the material drop port 92, which can ensure that the processing position of the dual-axis drill body 945 and the saw blade 944 corresponds to the processing position, realizing synchronous linkage of sawing and drilling, eliminating the need for step-by-step operation and improving processing efficiency.
