Description

Technical Field

[0001] The present application relates to the field of sawing technology, and in particular to a sawing tool and sawing equipment. Background Art

[0002] Water-cut products for car windows refer to external rubber sealing strips installed in the groove at the bottom edge of the door glass. They not only play a practical role in sealing and cleaning, but also contribute to the appearance of the vehicle. Because water-cut products are produced as straight strip semi-finished products through injection molding extrusion lines, they are then formed into products that match the shape of car windows through processes such as bending and sawing, and decorative end caps need to be installed at the ends. Before installing the decorative end caps at the ends of the water-cut products, the ends of the water-cut products need to be sawed so that the shape of the ends meets the requirements. Existing sawing tools cannot effectively discharge the waste after sawing is completed. There is a situation where waste is stuck in the sawing positioning structure, which requires frequent manual intervention. In the process of automated operation, it is easy to affect the sawing of the next water-cut product. Utility Model Content

[0031] Reference Figure 1 , an embodiment of the present application provides a sawing device, which includes a sawing tool 200.

[0032] Specifically, the sawing equipment also includes a frame 100 and a sawing head 110 . The sawing tool 200 is installed on the frame 100 . The sawing head 110 is installed on the frame 100 . The sawing head 110 is used to saw the external water-cut product 300 positioned and fixed on the sawing tool 200 .

[0033] Reference Figures 2 to 8 The embodiment of the present application provides a sawing tool 200, which includes a first positioning member 220, a first pressing assembly 230, a second pressing assembly 240 and a material taking assembly.

[0034] The first positioning assembly includes a first positioning member 220, which is used to position the inner side of the external water-cut product 300. The inner side of the external water-cut product 300 has a mounting groove. When the external water-cut product 300 is placed on the first positioning member 220, the mounting groove is pressed against the first positioning member 220.

[0035] Among them, when it is sensed that an external water-cut product 300 is placed on the first positioning member 220, the first clamping assembly 230 is activated. The first clamping assembly 230 is used to press against the side of the main part of the external water-cut product 300 to make the inner side of the external water-cut product 300 fit the first positioning member 220, thereby avoiding deformation of part of the external water-cut product 300 during sawing, which affects the shape and size of the sawing surface.

[0036] When it is sensed that an external water-cut product 300 is placed on the first positioning member 220, the second pressing assembly 240 can be activated simultaneously with the first pressing assembly 230, or the first pressing assembly 230 can be activated first and then the second pressing assembly 240. The second pressing assembly 240 is used to press against the side of the to-be-cut end 310 of the external water-cut product 300 so that the inner side of the external water-cut product 300 fits against the first positioning member 220. The sawing position of the external water-cut product 300 is located between the first pressing assembly 230 and the second pressing assembly 240. By respectively pressing the two sides of the sawing position of the external water-cut product 300 by the first pressing assembly 230 and the second pressing assembly 240, it can effectively reduce the large deviation in the shape and size of the sawing surface of the external water-cut product 300 during sawing.

[0037] The material taking component includes a material taking head 252 that can be extended toward the first positioning member 220 , and the material taking head 252 is used to clamp the end 310 to be cut of the external water-cut product 300 .

[0038] Specifically, after the outer water-cut product 300 that has been positioned and pressed is sawed, the material-taking head 252 of the material-taking component extends and moves to clamp the end 310 to be cut of the outer water-cut product 300 that has been sawed, and then the first clamping component 230 and the second clamping component 240 release the pressing action, and the material-taking head 252 retracts to pull the end 310 to be cut away from the first positioning member 220. When the end 310 to be cut is completely separated from the first positioning member 220, the material-taking head 252 releases the end 310 to be cut, realizing automatic discharge of sawing waste, effectively solving the problem of waste being stuck in the first positioning member 220 after sawing is completed, reducing the number of manual interventions, and being able to better adapt to the needs of automated production.

[0039] In some embodiments, as Figures 2 to 5 The first pressing assembly 230 includes two first pressing members 232 that can move toward each other or away from each other, and the first positioning member 220 is located between the two first pressing members 232. When the external water-cut product 300 is pressed against the first positioning member 220, the two first pressing members 232 can act simultaneously or sequentially to press the two sides of the external water-cut product 300 against the first positioning member 220, thereby preventing the inner part of the external water-cut product 300 from not being in close contact with the first positioning member 220 during the sawing process and affecting the cutting quality. After the sawing is completed, the two first pressing members 232 move away from each other so that the material-retrieving robot can remove the main part of the external water-cut product 300 that has been sawed, which is also convenient for the next discharge of the external water-cut product 300.

[0040] In some specific embodiments, the pressing surface of the first pressing member 232 is configured to be shaped to match the side surface of the external water-cut product 300; the movement of the first pressing member 232 is achieved by the first cylinder 231. Of course, in other embodiments, the movement of the first pressing member 232 can also be driven by an electric push rod or a screw motor. Furthermore, the movement of the first pressing member 232 can also be driven by other driving structures that can drive the first pressing member 232 to perform linear reciprocating motion.

[0041] In some embodiments, as Figures 2 to 5 The second pressing assembly 240 includes two second pressing members 242 that can move toward or away from each other, and the second positioning member is located between the two second pressing members 242. When the external water-cut product 300 is pressed against the first positioning member 220, the two second pressing members 242 can act simultaneously or successively to press the two sides of the external water-cut product 300 against the first positioning member 220, so as to avoid affecting the cutting quality due to the inner part of the external water-cut product 300 not being close to the first positioning member 220 during the sawing process. After the sawing is completed, the two second pressing members 242 move away from each other so that the material-retrieving robot can take away the main part of the external water-cut product 300 that has been sawed, which is also convenient for the next discharge of the external water-cut product 300.

[0042] In some specific embodiments, the pressing surface of the second pressing member 242 is configured to be shaped to match the side surface of the external water-cut product 300; the movement of the second pressing member 242 is achieved by the second cylinder 241. Of course, in other embodiments, the movement of the second pressing member 242 can also be driven by an electric push rod or a screw motor. Furthermore, the movement of the second pressing member 242 can also be driven by other driving structures that can drive the second pressing member 242 to perform linear reciprocating motion.

[0043] Some examples, such as Figures 6 to 8The positioning member includes a positioning tongue 221 that fits into the mounting groove of the external water-cut product 300. The positioning tongue 221 is provided with a notch 222 for circumventing the saw blade. The thickness of the positioning tongue 221 is slightly greater than the width of the mounting groove, allowing the external water-cut product 300 to be temporarily placed on the first positioning member 220 without falling off even when not being pressed by the pressing assembly. The width of the notch 222 only needs to be slightly greater than the thickness of the saw blade.

[0044] In some embodiments, the sawing tool 200 further includes a blowing member 260, the air outlet of the blowing member 260 facing the positioning tongue 221. Specifically, the blowing member 260 includes a blowing pipe and a control valve. Multiple blowing pipes are provided, and the air outlet of the blowing pipe extends below the positioning tongue 221 and toward the side of the positioning tongue 221, so as to be able to blow away the sawing waste remaining on the positioning tongue 221 to avoid affecting the positioning of the next external water-cut product 300.

[0045] In some embodiments, as Figures 2 to 4 As shown, the material removal head 252 includes two clamping blocks 2521 that can move toward or away from each other. In a specific embodiment, the material removal head 252 can be a parallel air gripper, with the two clamping blocks 2521 fixed to the two movable fingers of the parallel air gripper. Under the influence of airflow, the parallel air gripper drives the two clamping blocks 2521 to perform the clamping or release action.

[0046] The moving direction of the material taking head 252 is in the same straight line as the positioned and compacted external water-cut product 300 , so that the material taking head 252 can accurately clamp the end to be cut 310 .

[0047] In some embodiments, the sawing tool 200 further includes a mounting platform 210 , and the first positioning assembly, the first pressing assembly 230 , the second pressing assembly 240 and the material taking assembly are all fixed on the mounting platform 210 .

[0048] In some specific embodiments, the material picking assembly also includes a third cylinder 251, which is used to drive the material picking head 252 to perform telescopic movement, wherein the third cylinder 251 is fixed to the mounting platform 210, and the driving end of the third cylinder 251 is connected to the material picking head 252 through a connecting member 253, and the connecting member 253 is slidably set on the mounting platform 210.

[0049] like Figure 7 and Figure 8 As shown, the portion of the mounting platform 210 below the material taking head 252 is hollowed out to form a discharge gap 211 , so as to facilitate the discharge of the cut end 310 to be cut that is clamped by the material taking head 252 .

[0050] In some other embodiments, such as Figure 2 and Figure 3As shown, two first positioning members 220 can be provided, and the two first positioning members 220 respectively support the two ends of the external water-cut product 300 .

[0051] The sawing tool 200 also includes a second positioning assembly, which is fixed to the mounting platform 210. The second positioning assembly includes a second positioning member that can extend and retract toward the first positioning member 220. The second positioning member is used to position the end of the water-cut product 300. When the water-cut product 300 is sensed to be placed on the positioning tongue 221 of the first positioning member 220, the second positioning assembly is activated. The second positioning member moves toward the end of the first positioning member 220 and pushes against the end of the water-cut product 300, so that the band saw cutting position of the water-cut product 300 reaches the notch 222, facilitating subsequent sawing. The second positioning assembly serves to push the water-cut product 300 into place, reducing positional errors caused by the robot during material unloading and effectively improving sawing accuracy.

[0052] The extension and retraction of the second positioning member is achieved by the fourth cylinder 280, and the second positioning member is fixed to the cylinder rod of the fourth cylinder 280. In some embodiments, the extension and retraction of the second positioning member can also be driven by an electric push rod or a screw motor. Furthermore, the extension and retraction of the second positioning member can also be driven by other drive structures that can drive the second positioning member to perform linear reciprocating motion.

[0053] In some other embodiments, the sawing tool 200 also includes a sensor 270, which is used to sense the presence or absence of the external water-cut product 300 on the first positioning member 220, so that the controller can accurately control the first clamping assembly 230 and the second clamping assembly 240 according to the material loading and unloading conditions, thereby facilitating the operation of automated production.

[0054] In summary, the working process of the entire sawing tool 200 is as follows: the external robot places the material on the first positioning member 220. When the sensor 270 senses that the external water-cut product 300 is ready, it gives a signal to the controller. The controller first drives the second positioning member of the second positioning assembly to move and push against the end of the external water-cut product 300 to push the cutting position of the to-be-cut end 310 of the external water-cut product 300 to the notch 222. After the cutting position is set, the first clamping assembly 230 and the second clamping assembly 240 are activated, and the first The clamping assembly 230 and the second clamping assembly 240 respectively clamp the two sides of the sawing position of the external water-cut product 300, and then the sawing head 110 moves and saws off the end 310 to be cut; after the sawing is completed, the material taking head 252 moves to clamp the end 310 to be cut, and then the first clamping assembly 230 and the second clamping assembly 240 release the pressure against the external water-cut, so that the material taking head 252 can take the end 310 to be cut away from the first positioning member 220, completing the waste material discharge action, and avoiding the untimely discharge affecting the next sawing operation.

[0055] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
