Description

Technical Field

[0001] The invention relates to the technical field of workpiece processing equipment, in particular to workpiece fixed-length detection sawing equipment and a control method thereof. Background Art

[0002] Some workpieces with longer lengths need to be sawed using workpiece sawing equipment so that the length of the workpiece meets the processing requirements.

[0003] The workpiece sawing equipment generally includes a frame, a sawing device, a component and a positioning component. The sawing device is used to saw the workpiece so that the length of the workpiece meets the processing requirements. There are generally multiple positioning components, which are respectively arranged on both sides of the workpiece. The positioning components are used to limit the workpiece to prevent the workpiece from being offset when the sawing device is sawing the workpiece, thereby ensuring the sawing quality.

[0004] The sawing device and multiple positioning components of existing workpiece sawing equipment are generally fixed in specific positions, so that the length of the workpiece cut by the workpiece sawing device cannot be adjusted. When the length of the workpiece cut by the workpiece sawing device needs to be adjusted, the staff is generally required to disassemble the sawing device and install it to other positions, and adjust the position of the positioning component in accordance with the position of the sawing device to avoid the positioning component hindering the movement of the sawing device. The adaptability to workpieces with different length requirements is poor, and the adjustment process for workpieces with different length requirements is relatively cumbersome, which is not conducive to the factory's rapid adjustment of processed products and affects the factory's processing efficiency.

The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0056] Reference Figures 1 to 10 The workpiece fixed-length detection sawing device is provided with an upper and lower direction, a second direction and a first direction which are orthogonal to each other.

[0057] Reference Figure 1 and Figure 6The workpiece fixed-length detection sawing equipment includes: a frame 100, a material transport assembly 200, a workpiece supporting assembly 300, a zero fixing structure 400, a zero moving structure 500, a sawing assembly 600, a limit assembly 700, a fixed-length linkage assembly 800, a limit linkage assembly 900, and a support fine-tuning assembly 1000.

Specifically, in the present embodiment, a guide rail is arranged between the material transport component 200 and the frame 100. The guide rail is arranged between the material transport component 200 and the frame 100, so that the material transport component 200 can have a certain range of motion relative to the frame 100. The material transport component 200 can move a short distance relative to the frame 100 along the first direction to cooperate with other components, so as to avoid the material transport component 200 being fixed to the frame 100 and causing obstruction to the movement of other components.

[0060] Specifically, in this embodiment, an elastic material transport reset component (not shown in the figure) is arranged between the frame 100 and the material transport component 200. The elastic material transport reset component is configured as a spring structure. Both ends of the elastic material transport reset component are respectively abutted against the frame 100 and the material transport component 200. The elastic material transport reset component is used to drive the material transport component 200 to reset along the first direction.

[0061] Reference Figure 1 and Figure 6 Specifically, in the present embodiment, the material transport component 200 is configured as a conventional belt transmission structure, and the specific structure of the material transport component 200 is not repeated here.

[0065] The main part of the workpiece supporting unit 330 that supports the workpiece is set to the unit supporting roller 332, and the unit supporting roller 332 is set to be rotatably connected to the unit supporting bracket 331. When the workpiece is supported by the unit supporting roller 332, when the workpiece moves along the first direction relative to the workpiece supporting assembly 300, the friction between the workpiece and the workpiece supporting assembly 300 can be reduced, thereby reducing the occurrence of adverse conditions such as scratches on the workpiece surface.

[0066] A supporting drive structure 310 is arranged between the workpiece supporting assembly 300 and the frame 100. The supporting drive structure 310 is an electric linear drive mechanism. The supporting drive structure 310 is fixedly installed on the frame 100. The output end of the supporting drive structure 310 is fixed to the supporting connecting frame 320. The supporting drive structure 310 drives the workpiece supporting assembly 300 to move in the up and down directions so that the unit supporting roller 332 of the workpiece supporting assembly 300 is higher or lower than the uppermost end of the material transport assembly 200. The unit supporting roller 332 supports the workpiece to realize the conversion of the structure supporting the workpiece.

[0067] Specifically, in this embodiment, the unit support frame 331 of the workpiece supporting unit 330 is slidably connected to the frame 100, and the workpiece supporting unit 330 can slide along the first direction relative to the frame 100.

[0069] Reference Figure 1 , Figure 2 and Figure 6The zero fixing structure 400 is fixedly connected to the frame 100 , and the zero fixing structure 400 is disposed above one end of the workpiece supporting assembly 300 in the first direction.

[0070] The zeroing moving structure 500 is slidably connected to the frame 100 , and the zeroing moving structure 500 can slide relative to the frame 100 along a first direction.

[0072] When the zeroing movable structure 500 approaches the zeroing fixed structure 400, it will push the workpiece toward the zeroing fixed structure 400. The process of the workpiece approaching the zeroing fixed structure 400 is the process of workpiece zeroing. When the two ends of the workpiece are respectively in contact with the zeroing movable structure 500 and the zeroing fixed structure 400, the workpiece zeroing is completed.

[0073] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 The sawing assembly 600 is disposed above the workpiece supporting assembly 300.

In other embodiments, the sawing device 610 can also be configured to adopt a sawing structure of a saw blade. Those skilled in the art can select the specific structure of the sawing device 610 according to actual needs.

[0075] The first sawing movable frame 620 is installed on the frame 100, and the first sawing movable frame 620 is slidably connected to the frame 100 along a first direction. The first sawing driving structure 650 is arranged between the first sawing movable frame 620 and the frame 100. The first sawing driving structure 650 is fixed to the frame 100, and the output end of the first sawing driving structure 650 is fixed to the first sawing movable frame 620. The first sawing driving structure 650 is used to drive the first sawing movable frame 620 to move along the first direction to realize the position adjustment of the sawing device 610, so as to adapt to workpieces with different processing length requirements.

[0076] The sawing up and down moving frame 640 is installed on the first sawing moving frame 620, and the sawing up and down moving frame 640 is slidably connected with the first sawing moving frame 620 in the up and down direction.

So that the sawing device 610 approaches or moves away from the workpiece in the up and down direction, when the sawing device 610 moves away from the workpiece upward, the position of the sawing device 610 in the first direction can be adjusted.

The sawing device 610 is fixedly installed on the second sawing movable frame 630.

[0078] The second sawing driving structure 660 is used to drive the second sawing movable frame 630 to move along the second direction. Since the sawing device 610 is fixedly installed on the second sawing movable frame 630, the sawing device 610 will move along the second direction with the second sawing movable frame 630 to enable the sawing device 610 to saw the workpiece.

[0079] The sawing device 610 is driven to move in the first direction, the second direction and the up and down directions respectively by the first sawing drive structure 650, the second sawing drive structure 660 and the sawing up and down drive structure 670 to achieve the position adjustment, sawing workpiece and approaching and moving away from the workpiece of the sawing device 610.

[0080] Specifically, when the first sawing drive structure 650 is working, it drives the first sawing movable frame 620 to move along the first direction. During this process, the sawing device 610, the second sawing movable frame 630, the sawing upper and lower movable frame 640, the second sawing drive structure 660, and the sawing upper and lower drive structure 670 will move along the first direction with the first sawing movable frame 620, so that the sawing device 610 moves to the designated cutting position.

[0081] When the first sawing movable frame 620 moves into position, the first sawing drive structure 650 stops working, and then the sawing upper and lower drive structure 670 starts working, driving the sawing upper and lower movable frame 640 to move in the up and down directions. The sawing device 610, the second sawing movable frame 630, and the second sawing drive structure 660 will move in the up and down directions with the sawing upper and lower movable frame 640, so that the sawing device 610 is close to the workpiece.

[0089] Reference Figure 2 , Figure 3 and Figure 8 A fine-adjustment follower structure 1100 is provided between the sawing assembly 600 and the support fine-adjustment structure 1010. The sawing device 610 is linked with the support fine-adjustment structure 1010 through the fine-adjustment follower structure 1100, so that when the sawing device 610 moves along the first direction, the support fine-adjustment structure 1010 also moves along the first direction, and the movement direction of the support fine-adjustment structure 1010 is the same as that of the sawing device 610, and the speed is equal.

[0090] Specifically, the fine-tuning follower structure 1100 includes three fine-tuning linkage structures, and the fine-tuning linkage structure includes two fine-tuning connecting wheels 1110 and a fine-tuning connecting belt 1120. The fine-tuning connecting wheels 1110 are rotatably mounted on the frame 100, and the fine-tuning connecting belt 1120 bypasses the two fine-tuning connecting wheels 1110, and the fine-tuning connecting wheels 1110 are in transmission connection with the fine-tuning connecting belt 1120.

[0091] Specifically, in the present embodiment, the fine-tuning connecting belt 1120 is configured as a synchronous belt, and the fine-tuning connecting wheel 1110 is configured as a synchronous pulley. The three fine-tuning linkage structures are respectively configured as the third fine-tuning linkage structure 1103, the second fine-tuning linkage structure 1102 and the first fine-tuning linkage structure 1101. The fine-tuning connecting belts 1120 of the third fine-tuning linkage structure 1103 and the first fine-tuning linkage structure 1101 are both installed with fine-tuning connecting seats 1130. The two fine-tuning connecting wheels 1110 of the second fine-tuning linkage structure 1102 are respectively fixed to the fine-tuning connecting wheels 1110 of the third fine-tuning linkage structure 1103 and the fine-tuning connecting wheels 1110 of the first fine-tuning linkage structure 1101, thereby realizing power transmission among the third fine-tuning linkage structure 1103, the second fine-tuning linkage structure 1102 and the first fine-tuning linkage structure 1101. Specifically, in the present embodiment, the fine-tuning connecting seat 1130 (i.e. Figure 3 The fine-tuning connecting seat 1130 located at the top is fixedly connected to the first sawing movable frame 620. When the first sawing movable frame 620 moves along the first direction, it will drive the sawing device 610 and the fine-tuning connecting seat 1130 of the first fine-tuning linkage structure 1101 to move along the first direction.

[0092] The support fine-tuning structure 1010 and the fine-tuning connection seat 1130 of the third fine-tuning linkage structure 1103 are relatively fixed (ie, the support fine-tuning structure 1010 and the fine-tuning connection seat 1130 are relatively fixed). Figure 3The fine-tuning connection seat 1130 located at the bottom is fixedly connected so that the support fine-tuning structure 1010 can be adjusted at any time. Figure 3 The fine-tuning connection seat 1130 located at the bottom moves along the first direction), the third fine-tuning linkage structure 1103 has the same movement direction and speed as the fine-tuning connection seat 1130 of the first fine-tuning linkage structure 1101, that is, the fine-tuning connection seat 1130 of the first fine-tuning linkage structure 1101 and the third fine-tuning linkage structure 1103 move synchronously.

[0093] The synchronous movement of the first fine-tuning linkage structure 1101 and the fine-tuning connection seat 1130 of the third fine-tuning linkage structure 1103 will cause the supporting fine-tuning structure 1010 and the sawing device 610 to move synchronously.

[0094] Specifically, refer to Figure 1 , Figure 2 and Figure 7 The limit assembly 700 is disposed on one side of the sawing device 610 close to the zero fixing structure 400. There are multiple limit assemblies 700, and the multiple limit assemblies 700 are all disposed above the workpiece supporting assembly 300. The multiple limit assemblies 700 are divided into two groups, and the two groups of limit assemblies 700 are respectively disposed on both sides of the workpiece supporting assembly 300.

[0095] The plurality of position limiting components 700 are all installed on the position limiting movable frame 701 , and the position limiting components 700 are movably connected to the position limiting movable frame 701 .

[0096] Reference Figure 7 The limit assembly 700 includes an upper limit driving structure 710 , an upper limit structure 720 , a side limit driving structure 730 and a side limit structure 740 .

[0097] Specifically, in this embodiment, multiple limit assemblies 700 share the same upper limit drive structure 710, which is disposed between the limit moving frame 701 and the frame 100. The upper limit drive structure 710 is configured as an electric linear drive device, which is fixedly mounted on the frame 100, and the output end of the upper limit drive structure 710 is fixed to the limit moving frame 701. The upper limit structure 720 is mounted on the limit moving frame 701, and the upper limit drive structure 710 drives the limit moving frame 701 to move in the up-down direction, thereby driving multiple upper limit structures 720 to move in the up-down direction at the same time.

[0098] In other embodiments, each upper limit structure 720 may be equipped with an upper limit driving structure 710 separately, and those skilled in the art may select the number of upper limit driving structures 710 according to actual needs.

[0099] The side limit driving structure 730 is fixedly mounted on the limit moving frame 701, and the side limit driving structure 730 moves along the up and down directions with the limit moving frame 701. The output end of the side limit driving structure 730 is fixed with a side limit mounting frame 702, and the side limit mounting frame 702 is slidably connected with the limit moving frame 701 along the second direction (a guide rail and other structures are arranged between the side limit mounting frame 702 and the limit moving frame 701), and multiple side limit structures 740 are all installed on the side limit mounting frame 702. The side limit driving structure 730 drives the side limit mounting frame 702 to approach or move away from the center plane of the workpiece supporting assembly 300, thereby driving the side limit structure 740 to approach or move away from the center plane of the workpiece supporting assembly 300.

[0100] The limiting assembly 700 farthest from the sawing assembly 600 on each side of the workpiece supporting assembly 300 is set as a limiting fixing assembly, and the limiting fixing assembly is relatively fixed to the position of the frame 100 in the first direction (specifically, the limiting fixing assembly is fixedly connected to the side limiting mounting frame 702), and the limiting movable frame 701 can slide relatively in the up and down direction relative to the frame 100. The side limiting structure 740 of the limiting fixing assembly is relatively fixed to the side limiting mounting frame 702.

[0101] Specifically, in this embodiment, multiple side limit structures 740 located on the same side of the workpiece support assembly 300 are connected to the same side limit driving structure 730, so as to achieve synchronous movement of multiple side limit structures 740 on the same side of the workpiece support assembly 300. In other embodiments, each side limit structure 740 may be equipped with a side limit driving structure 730, and those skilled in the art may select the number of side limit driving structures 730 according to actual needs.

[0102] The upper limit driving structure 710 drives the upper limit structure 720 to move downward to approach the workpiece, so as to limit the upper side of the workpiece, and can adapt to workpieces of different thicknesses or heights. The side limit driving structure 730 drives the side limit structure 740 to approach the workpiece along the second direction, and the multiple side limit structures 740 located on both sides of the workpiece supporting assembly 300 limit the two sides of the workpiece respectively, and can adapt to workpieces of different widths.

[0103] When the upper limit driving structure 710 is working, it drives the limit moving frame 701 to move up and down. During the up and down movement of the limit moving frame 701, the side limit mounting frame 702, the side limit driving structure 730, the side limit structure 740, the upper limit structure 720 and other components will move up and down with the limit moving frame 701.

[0104] When the limit moving frame 701 moves to the specified position, the upper limit structure 720 contacts the upper end of the workpiece, thereby limiting the upper end of the workpiece. Then the side limit driving structure 730 works, driving the side limit mounting frame 702, the side limit structure 740, the upper limit structure 720 and other structures to move along the second direction, so that the side limit structures 740 located on both sides of the center plane approach each other along the second direction, thereby adapting to workpieces of different widths; in the process of the side limit structures 740 located on both sides of the center plane approaching each other, the heights of the side limit structures 740 and the upper limit structure 720 do not change. When the side limit structure 740 abuts against the side wall of the workpiece, the side wall of the workpiece can be limited, thereby avoiding undesirable situations such as tilting of the workpiece during sawing.

[0105] The upper limit structure 720 and the side limit structure 740 are used to fix the workpiece, so that the workpiece can be prevented from being deviated when the sawing device 610 is sawing, thereby ensuring the sawing quality of the workpiece.

[0106] Specifically, refer to Figure 1 , Figure 2 and Figure 5 The limit assembly 700 closest to the sawing device 610 is set as a main limit moving assembly, and a fixed-length linkage assembly 800 is arranged between the main limit moving assembly and the sawing assembly 600. The fixed-length linkage assembly 800 is used to drive the main limit moving assembly so that the main limit moving assembly moves along the first direction with the sawing device 610 to maintain a certain distance between the main limit moving assembly and the sawing device 610.

[0107] Reference Figure 2 , Figure 4 , Figure 5 and Figure 7 Specifically, the fixed-length linkage assembly 800 includes a connecting frame, the upper end of which is slidably connected to the first sawing movable frame 620 of the sawing assembly 600 along the up and down directions, and the lower end of the connecting frame is fixedly connected to the main limit movable assembly.

[0108] Through such an arrangement, the first sawing movable frame 620 can be connected to the main limit movable assembly. When the first sawing movable frame 620 moves along the first direction, driven by the connecting frame body of the fixed-length linkage assembly 800, the main limit movable assembly can move along with the first sawing movable frame 620 along the first direction, so as to avoid the main limit movable assembly being fixedly set on the frame 100 and hindering the first sawing movable frame 620 from moving along the first direction, thereby allowing the first sawing movable frame 620 to move a longer distance in the first direction, so that the workpiece fixed-length detection sawing equipment can process more workpieces of different lengths.

[0109] By setting a fixed-length linkage assembly 800 between the first sawing movable frame 620 and the main limit movable assembly, the sawing device 610 will drive the main limit movable assembly to move along the first direction during its movement along the first direction, thereby realizing the linkage between the sawing device 610 and the main limit movable assembly in the first direction.

[0110] When the upper limit driving structure 710 works and causes the side limit structure 740 and the upper limit structure 720 to move up and down relative to the first sawing movable frame 620, the connecting frame body of the fixed-length linkage assembly 800 is slidably connected to the first sawing movable frame 620 along the up and down directions, so that the side limit structure 740 and the upper limit structure 720 can still maintain a certain distance from the sawing assembly 600 during the up and down movement.

[0111] Specifically, in other embodiments, the two groups of limiting components 700 located on both sides of the workpiece supporting component 300 may be arranged in a staggered manner.

[0112] The two groups of limiting components 700 disposed on both sides of the workpiece supporting component 300 are staggered to further ensure that the workpiece is not easily offset when the limiting components 700 limit the workpiece.

[0113] Reference Figure 6 , Figure 7 Specifically, a limit linkage assembly 900 is disposed between two adjacent limit assemblies 700. The limit linkage assembly 900 includes two connecting rods 910 and a first linkage connector 920.

[0114] The two connecting rods 910 are equal length members, the first linkage connector 920 is disposed between the two connecting rods 910, one end of the connecting rod 910 is hinged to the first linkage connector 920, and the other end of the connecting rod 910 is hinged to the limit assembly 700. The connecting rod 910 is tilted relative to the first linkage connector 920.

[0115] Specifically, multiple limit linkage assemblies 900 are connected via a second linkage connector 930, multiple first linkage connectors 920 are all slidably connected to the second linkage connector 930, the first linkage connector 920 can be slidably connected along a first direction relative to the second linkage connector 930, the second linkage connector 930 is slidably connected to the frame 100, and the second linkage connector 930 can move along the up and down directions relative to the frame 100.

[0116] When one of the limit assemblies 700 moves in the first direction, the inclination angle of the connecting rod 910 relative to the first linkage connecting member 920 changes, and the first linkage connecting member 920 remains horizontally set, so that the other connecting rod 910 in the same limit linkage assembly 900 also changes accordingly, thereby making the two limit assemblies 700 connected by the same limit linkage assembly 900 approach each other or move away from each other; at the same time, since multiple first linkage connecting members 920 are connected by the second linkage connecting member 930, the first linkage connecting member 920 will drive the second linkage connecting member 930 to move in the up and down directions, thereby realizing that multiple first linkage connecting members 920 move in the up and down directions at the same time, thereby making multiple limit assemblies 700 approach each other or move away from each other. Through such a setting, the distances between multiple limit assemblies 700 are equal, so that the force on the workpiece is more uniform, which can effectively avoid damage to the workpiece caused by excessive local force on the workpiece.

[0117] Reference Figures 9 to 11 , a workpiece fixed-length detection sawing equipment control method comprises the following steps:

[0118] If the position of the sawing device 610 does not meet the workpiece processing requirements, the following steps are performed until the position of the sawing device 610 meets the workpiece processing requirements:

[0119] Step S100 , the sawing device 610 moves along a first direction, and the fixed-length linkage assembly 800 drives the main limit moving assembly to move along with the sawing device 610 along the first direction, and a certain distance is maintained between the main limit moving assembly and the sawing device 610 .

[0120] Through step S100, the main limit moving assembly can be prevented from being too close to the sawing device 610, so as to prevent the sawing device 610 from accidentally sawing the limit assembly when sawing a workpiece, thereby ensuring that the limit assembly can work normally for a long time.

[0121] After the position of the sawing device 610 meets the workpiece processing requirements, the following steps are performed:

[0122] In step S200 , the material transporting assembly 200 transports the workpiece to above the workpiece supporting assembly 300 , and then the material transporting assembly 200 stops working, and the workpiece supporting assembly 300 rises to lift the workpiece.

[0123] Step S300 , the zeroing movable structure 500 approaches the zeroing fixed structure 400 along a first direction, and after two ends of the workpiece abut against the zeroing movable structure 500 and the zeroing fixed structure 400 respectively, the zeroing of the workpiece is completed.

[0124] Step S400, the limiting assembly 700 descends, and the limiting assembly 700 limits the workpiece; the sawing device 610 moves downward to a specified position, and then moves along the second direction to saw the workpiece.

[0125] In step S400, the upper limit driving structure 710 of the limiting assembly 700 drives the upper limit structure 720 to move downward to approach the workpiece, and the side limiting driving structure 730 drives the side limiting structure 740 to approach the workpiece along the second direction.

[0126] Step S500: The sawing device 610 moves downward, and then moves along the second direction to saw the workpiece.

[0127] In step S600, the sawing device 610 and the workpiece supporting assembly 300 are reset (i.e., the sawing device 610 moves upward and the workpiece supporting assembly 300 descends), and the material transport assembly 200 starts working. The material transport assembly 200 transports the sawed workpiece and the remaining waste after sawing to the equipment required for the next process.

[0128] Reference Figures 9 to 11 When the position of the sawing device 610 does not meet the workpiece processing requirements, the following steps are also included:

[0129] Step S700 , the workpiece supporting assembly 300 moves downward so that the support guide structure 1020 installed on the workpiece supporting assembly 300 is lower than the guide channel 1011 to prevent the support guide structure 1020 from hindering the support fine-tuning structure 1010 from moving along the first direction in subsequent steps.

[0130] Step S700 is performed before step S100 , and step S100 further includes: when the sawing device 610 moves along the first direction, the support fine-tuning assembly 1000 moves along the first direction with the sawing device 610 .

[0131] Step S800, when the sawing device 610 moves to the specified position, the workpiece supporting assembly 300 rises. If a workpiece supporting unit 330 is too close to the sawing device 610 in the first direction, the support guide structure 1020 of the workpiece supporting unit 330 closest to the sawing device 610 first enters the guide channel 1011, and the support guide structure 1020 is guided by the guide channel 1011 and moves in the direction away from the sawing device 610, and then the support guide structure 1020 enters the limiting channel 1012.

[0132] Step S800 is performed after step S100.

[0133] By setting steps S700 to S800 , the workpiece supporting unit 330 closest to the sawing device 610 can be automatically moved away, thereby preventing the sawing device 610 from sawing the workpiece supporting unit 330 , thereby ensuring long-term normal operation of the workpiece supporting assembly 300 .

[0134] In step S600, when the workpiece supporting assembly 300 descends, the supporting guide structure 1020 always moves in the limiting channel 1012. When the position of the sawing device 610 in the first direction does not need to be changed, the position of the workpiece supporting assembly 300 closest to the sawing device 610 in the first direction will not change either, thereby avoiding the workpiece supporting assembly 300 from repeatedly moving back and forth, and avoiding repeated compression and recovery of the supporting elastic reset member 340 between the workpiece supporting assembly 300 and the frame 100, thereby ensuring the service life of the supporting elastic reset member 340.

[0135] Specifically, the working process of the workpiece fixed-length detection sawing equipment is as follows:

[0136] First, the material transporting assembly 200 transports the workpiece to the top of the workpiece supporting assembly 300 , and then the supporting driving structure 310 drives the workpiece supporting unit 330 to rise, so that the workpiece is separated from the transporting surface of the material transporting assembly 200 .

[0137] After the workpiece leaves the transport surface of the material transport assembly 200, the zero driving structure 510 drives the zero moving structure 500 to approach the zero fixed structure 400 along the first direction. During the movement of the zero moving structure 500, the workpiece will be driven to approach the zero fixed structure 400. When the end of the workpiece abuts against the zero fixed structure 400, the zero driving structure 510 stops working.

[0138] After the workpiece is zeroed, the upper limit driving structure 710 works to drive the side limit structure 740 and the upper limit structure 720 to move downward, so that the side limit structure 740 and the upper limit structure 720 are close to the workpiece. When the upper limit structure 720 moves to contact with the upper end of the workpiece, the upper limit structure 720 limits the upper end of the workpiece. Then, the side limit driving structure 730 works to drive the side limit structure 740 to approach the center plane, so that the side limit structure 740 moves along the second direction and gradually approaches the workpiece until the side limit structure 740 abuts against the side wall of the workpiece in the second direction. Then, the side limit driving structure 730 stops working and the workpiece is fixed.

[0139] After the workpiece is fixed, the first sawing drive structure 650 drives the first sawing movable frame 620 to move in the first direction, and the sawing device 610 moves along with the first sawing movable frame 620 in the first direction. When the sawing device 610 moves to the set position (the set position here is set according to the workpiece length required by the customer), the first sawing drive structure 650 stops working. Then the sawing upper and lower drive structure 670 works to drive the sawing upper and lower movable frame 640 to move downward, and the sawing device 610 moves downward with the sawing upper and lower movable frame 640, so that the sawing device 610 moves downward to the workpiece. When the sawing device 610 moves to the specified height (the lowermost end of the sawing device 610 is required to be lower than the lowermost end of the workpiece, so that the sawing device 610 can completely cut off the workpiece during the subsequent movement), the sawing upper and lower drive structure 670 stops working. Then, the second sawing driving structure 660 works to drive the second sawing movable frame 630 to move in the second direction. The sawing device 610 moves along with the second sawing movable frame 630 in the second direction, and the sawing device 610 saws the workpiece.

[0140] After the workpiece is sawn, the zero moving structure 500, the limit assembly 700, and the workpiece supporting assembly 300 are reset, and the sawing device 610 of the sawing assembly 600 is reset in the vertical direction. When the workpiece supporting assembly 300 is reset, the uppermost end of the unit supporting roller 332 is lower than the transport surface.

[0141] When the next batch of workpieces are transported to the top of the workpiece supporting assembly 300 by the material transport assembly 200, if the required length of the next batch of workpieces has not changed, the workpiece fixed-length detection sawing equipment repeats the above process, but there is no need to readjust the position of the sawing device 610 in the first direction.

[0142] If the sawing length required for the next batch of workpieces is not equal to the sawing length required for the previous batch of workpieces, perform the following actions:

[0143] The supporting driving structure 310 drives the workpiece supporting unit 330 to descend. During the process of the workpiece supporting unit 330 descending, the supporting guiding structure 1020 will descend along with the workpiece supporting unit 330 .

[0144] When the support guide structure 1020 drops to a position lower than the lowermost end of the support fine-tuning structure 1010, the first sawing drive structure 650 drives the first sawing movable frame 620 to move along the first direction, and the sawing device 610 moves with the first sawing movable frame 620 again. Since the fine-tuning connecting seat 1130 of the first fine-tuning linkage structure 1101 is fixedly connected to the first sawing movable frame 620, the support fine-tuning structure 1010 is fixedly connected to the fine-tuning connecting seat 1130 of the third fine-tuning linkage structure 1103, and the third fine-tuning The linkage structure 1103 is linked with the first fine-tuning linkage structure 1101 through the second fine-tuning linkage structure 1102. When the first sawing movable frame 620 moves along the first direction, the fine-tuning connecting seat 1130 of the third fine-tuning linkage structure 1103 will also move along the first direction, thereby driving the supporting fine-tuning structure 1010 fixedly installed on the fine-tuning connecting seat 1130 of the third fine-tuning linkage structure 1103 to move along the first direction, so that the supporting fine-tuning structure 1010 is always located directly below the sawing device 610.

[0145] After the sawing device 610 moves to the designated position, the first sawing driving structure 650 stops working, and then the supporting driving structure 310 drives the workpiece supporting unit 330 to rise.

[0146] If the support guide structure 1020 is located directly below the support fine-tuning structure 1010 before the workpiece supporting unit 330 rises, the support guide structure 1020 will be guided by the guide channel 1011 during the rising process, and gradually move along the first direction during the rising process and finally enter the limiting channel 1012, so that the workpiece supporting unit 330 moves a certain distance along the first direction, thereby allowing the workpiece supporting unit 330 to avoid the sawing device 610, so as to avoid the sawing device 610 accidentally cutting the workpiece supporting unit 330 during sawing, thereby ensuring that the workpiece fixed-length detection sawing equipment can operate normally for a long time.

[0147] If the support guide structure 1020 is not directly below the support fine-tuning structure 1010 before the workpiece supporting unit 330 rises, the workpiece supporting unit 330 will be misaligned with the sawing device 610 when it is fully raised, and there is no need for the workpiece supporting unit 330 to move along the first direction. During the rising process of the workpiece supporting unit 330, the support guide structure 1020 will not contact the support fine-tuning structure 1010. Through the cooperation of the support guide structure 1020 and the support fine-tuning structure 1010, the workpiece supporting unit 330 can always be misaligned with the sawing device 610, so that no matter what length of workpiece needs to be processed, the sawing device 610 can avoid accidentally sawing the unit supporting roller 332 of the workpiece supporting unit 330. As for the material transporting assembly 200, since the uppermost end of the workpiece supporting unit 330 is higher than the transport surface of the material transporting assembly 200 during the sawing process, the sawing device 610 will not saw the material transporting assembly 200.

[0148] After the workpiece supporting unit 330 is fully raised, the workpiece sawing operation continues.
