Description

Object cutting and absorbing mechanism and object cutting and absorbing system

The present disclosure relates to a cutting and absorbing technology, and in particular to an object cutting and absorbing mechanism and an object cutting and absorbing system.

Currently, most objects that are subjected to the pasting operation are pre-cut and then picked up and pasted by manual or automated equipment.

For example, a heat sink is cut to the required size in advance, and then the worker manually takes the heat sink and attaches it to the attachment to be attached. Alternatively, an automated device takes the heat sink and attaches it to the attachment to be attached.

However, most pre-cut heat sinks are packed in stacks. Due to the compression of the stacking weight, the heat sinks on the bottom layer are prone to sticking, which increases the abnormality rate in automated production and leads to production capacity loss.

In order to improve the sticking problem, a work plate is used, and the heat sink is placed on the work plate, so that the heat sink is separated by the work plate, which can effectively improve the sticking. However, the use of the work plate leads to increased costs, which is still not ideal.

Therefore, one of the purposes of the present disclosure is to provide an object cutting and sucking mechanism and an object cutting and sucking system, which can improve the problem that objects are stacked and easily stick together after being pre-cut, and the problem that objects are separated by working plates and the cost is high.

According to the above-mentioned purpose of the present disclosure, a kind of object cutting and sucking mechanism is proposed. The object cutting and sucking mechanism comprises a base, a cutting die, a moving part and a sucking device. The cutting die and the moving part are both arranged on the base. The sucking device is arranged on the moving part and extends into the cutting die. The sucking device moves relative to the cutting die by the moving part. The sucking device is connected to a vacuum supply part. While the cutting die cuts out the object, the sucking device vacuum absorbs the object.

According to one embodiment of the present disclosure, the knife mold includes a substrate, a knife head and a positioning column. The substrate is arranged on the base. The substrate has a first surface and a second surface opposite to each other. The first surface faces the base. The knife head is arranged on the second surface of the substrate. A through hole and a blade are formed at one end of the knife head. The through hole penetrates the knife head and extends to the first surface of the substrate. The blade surrounds the through hole. The positioning column is arranged on the substrate and extends into the base.

According to an embodiment of the present disclosure, the suction device includes a suction head and a flow channel. The suction head is slidably matched with the perforation. The end surface of the suction head forms a through hole. The flow channel is formed in the suction device. The flow channel connects the vacuum supply part and the through hole.

According to one embodiment of the present disclosure, the suction head includes a bump, a groove and a ring wall. The bump is formed on the end surface of the suction head and is arranged at intervals. The groove is formed on the end surface of the suction head. The groove surrounds the bump and is connected to the through hole. The ring wall is formed on the end surface of the suction head and surrounds the groove, and the ring wall is flush with the bump.

According to one embodiment of the present disclosure, the object is a heat sink and the moving part is a cylinder.

According to an embodiment of the present disclosure, the moving member includes a cylinder body, a cylinder core and a moving seat. The cylinder body is fixed to the seat. The cylinder core is arranged in the cylinder body and can move relative to the cylinder body. The moving seat is arranged in the cylinder core and extends out of the cylinder body. The suction device is arranged on the moving seat, and the suction head is moved along the perforation by the driving of the moving seat.

According to one embodiment of the present disclosure, the moving seat is L-shaped. The moving seat includes a mounting portion and a guide arm. The mounting portion is disposed on the cylinder core. The mounting portion is between the cylinder body and the suction device, and the suction device is disposed on the mounting portion. The guide arm is disposed on the mounting portion. The guide arm forms a convex portion on the side surface facing the cylinder body. The convex portion contacts the cylinder body.

According to an embodiment of the present disclosure, the base includes a mounting plate and mounting feet. The moving member is disposed on the mounting plate. The mounting feet are disposed on the end surface of the mounting plate. The mounting feet are spaced apart from each other. The moving member is disposed on the outer side surface of the mounting plate. The suction device is located between the mounting feet. The knife mold is disposed across the mounting feet.

According to one embodiment of the present disclosure, the positioning posts of the cutting die extend into the mounting feet respectively.

According to the above-mentioned purpose of the present disclosure, an object cutting and sucking system is proposed. The object cutting and sucking system includes a robot arm and the above-mentioned object cutting and sucking mechanism. The object cutting and sucking mechanism is arranged on the robot arm. The robot arm drives the object cutting and sucking mechanism to move, and uses the cutting die to cut out the object, and at the same time the suction device vacuum absorbs the object. Then the robot arm moves the object cutting and sucking mechanism to the attachment to be attached. The moving part drives the suction device to make the object separate from the cutting die, so that the object is attached to the attachment to be attached, and at the same time the suction device breaks the vacuum to make the object separate from the suction device.

The mechanical arm of the object cutting and suction system disclosed in the present invention can drive the object cutting and suction mechanism to allow the die cutter to perform the cutting action. While the die cuts the object, the suction device vacuum absorbs the object. Then the object is attached to the attachment to be attached. Therefore, there is no need to prepare and place the material before cutting, which can effectively prevent the objects from stacking and sticking, thereby reducing the abnormal rate and improving the overall utilization rate. In addition, there is no need to provide a work plate for material placement, thereby reducing costs.

In one example, the outer contour shape of the blade 122b when viewed from below can match the outer contour shape of the through hole 122h when viewed from below, that is, when the outer contour shape of the through hole 122h when viewed from below is a quadrilateral, the outer contour shape of the blade 122b when viewed from below is also a quadrilateral. The shape matching can help ensure the accuracy and stability of vacuum adsorption.

As shown in FIG. 2 , the positioning post 123 is disposed in the substrate 121 and protrudes from the first surface 121f of the substrate 121, and the positioning post 123 extends into the positioning hole 113 of the mounting foot 112 of the base 110. When the cutting die 120 is disassembled or replaced, the cooperation between the positioning post 123 and the positioning hole 113 allows the cutting die 120 to be quickly positioned, thereby improving assembly convenience.

As shown in FIG1A , the moving member 130 is disposed on the base 110. In one example, the moving member 130 is disposed on the front side surface of the mounting plate portion 111. In one example, the moving member 130 can be a cylinder. As shown in FIG1A and FIG1B , the moving member 130 includes a cylinder body 131, a cylinder core 132, and a moving base 133. The cylinder body 131 is fixedly disposed on the base 110. In one example, the cylinder body 131 is fixedly disposed on the front side surface of the mounting plate portion 111. As shown in FIG1A , the cylinder core 132 is disposed on the cylinder body 131, and one end of the cylinder core 132 extends out of the cylinder body 131. The cylinder core 132 is moved relative to the cylinder body 131 by utilizing the change in the direction of gas entering and exiting the cylinder body 131, that is, the cylinder core 132 can move up and down relative to the cylinder body 131 when viewed from the orientation shown in FIG1A .

As shown in Figures 1A and 1B, the moving seat 133 is disposed at the bottom end of the cylinder core 132, that is, the moving seat 133 is disposed in the cylinder core 132 and extends out of one end of the cylinder body 131. The moving seat 133 moves with the cylinder core 132. In other words, the moving seat 133 moves with the cylinder core 132. Therefore, when the cylinder core 132 moves relative to the cylinder body 131, the moving seat 133 also moves relative to the cylinder body 131. In one example, the moving seat 133 may be L-shaped. The moving seat 133 includes an assembly portion 1331 and a guide arm 1332. The assembly portion 1331 is disposed in the cylinder core 132 and extends out of one end of the cylinder body 131.

The inner side surface of the guide arm 1332 forms a convex portion 1332p, and the convex portion 1332p faces and contacts the cylinder body 131. The convex portion 1332p can help improve the stability of the moving seat 133 moving up and down.

As shown in FIG. 1A and FIG. 1C , the suction device 140 is disposed on the moving member 130. That is, the suction device 140 is disposed on the side surface of the assembly portion 1331 of the moving seat 133 relative to the cylinder core 132, and the assembly portion 1331 is located between the cylinder body 131 and the suction device 140. The suction device 140 extends into the cutting die 120, and the suction device 140 moves relative to the cutting die 120 using the moving member 130. That is, the suction device 140 moves with the moving seat 133, and the portion of the suction device 140 that extends into the cutting die 120 can move along the through hole 122h. The suction device 140 can be connected to a vacuum supply component and cooperate with the vacuum supply component to perform a vacuum adsorption operation. The vacuum supply component can be, for example, a vacuum pump. The suction device 140 can further perform a vacuum breaking operation. As shown in FIG. 1A , FIG. 2 and FIG. 3 , the suction device 140 includes a connection seat 141 , a connection head 142 , a suction head 143 and a flow channel 144 .

The connecting seat 141 is disposed on the moving seat 133, and the connecting seat 141 moves together with the moving seat 133. As shown in FIG1B , when the cylinder core 132 drives the moving seat 133 to move up and down, the connecting seat 141 also moves up and down with the moving seat 133. In other words, the moving member 130 can drive the connecting seat 141 of the suction device 140. In addition, the connecting seat 141 is located between the mounting feet 112, and the connecting seat 141 is located between the mounting plate 111 and the cutting die 120. The portion of the connecting seat 141 that extends laterally from the mounting plate 111 is fixed to the moving seat 133 to facilitate the operation of disassembling the connecting seat 141 from the moving seat 133.

The connector 142 is disposed on the connector base 141 and connected to the vacuum supply. As shown in FIG. 1A , the connector 142 is disposed on a portion of the connector base 141 that extends laterally out of the mounting plate 111 , that is, the connector 142 is disposed on the front end surface of the connector base 141 .

As shown in FIG. 1C , FIG. 2 and FIG. 3 , the suction head 143 is slidably matched with the perforation 122h, that is, the degree of match that the suction head 143 moves smoothly in the perforation 122h along an axial direction of the cutting die 120. As shown in FIG. 1C and FIG. 4 , a through hole 143h is formed on the end face of the suction head 143, that is, a through hole 143h is formed at the end face of the suction head 143 adjacent to the blade 122b. In one example, the through holes 143h are arranged in a matrix on the end face of the suction head 143. In one example, some of the through holes 143h are adjacent to the outer edge of the suction head 143 and are arranged at intervals from each other to further enclose an area. The remaining through holes 143h are located in this area and are adjacent to the center of the end face of the suction head 143. The distribution configuration of the through holes 143h makes the vacuum adsorption force more evenly distributed.

As shown in FIG4 , the suction head 143 further includes a plurality of bumps 143p, a plurality of grooves 143g and a ring wall 143w. The bumps 143p are formed on the end surface of the suction head 143 and are arranged at intervals from each other. The sizes of the bumps 143p may be the same or different. The grooves 143g are formed on the end surface of the suction head 143, wherein the grooves 143g surround the bumps 143p and are connected to the through holes 143h. The ring wall 143w is formed on the end surface of the suction head 143 and surrounds the grooves 143g. The ring wall 143w is flush with the bumps 143p, that is, the end surface of the ring wall 143w is flush with the end surface of the bump 143p. By configuring the groove 143g and the protrusion 143p, the contact area between the suction head 143 and the object 150 can be reduced, thereby reducing the adhesion strength between the object 150 and the suction head 143. In one example, the suction head 143 can be a component made of polyetheretherketone material. By selecting appropriate materials, the adhesion strength of the object 150 adhering to the suction head 143 can be reduced.

The flow channel 144 is formed in the suction device 140. The flow channel 144 extends the connection head 142 and the connection seat 141, and the flow channel 144 connects the vacuum supply part and the through hole 143h. The inner diameter of the flow channel 144 can be uniform or unequal.

According to the size of the object 150 to be cut, the appropriate size of the cutting die 120 can be replaced, and the suction device 140 that matches the cutting die 120 can also be replaced together. During the removal operation, the locking piece 160 is first removed, and the cutting die 120 is removed from the mounting foot 112. Then the suction device 140 is removed from the moving part 130. Then the suction device 140 to be installed is set on the assembly part 1331 of the moving seat 133. The cutting die 120 to be installed uses the positioning column 123 to extend into the positioning hole 113 of the mounting foot 112, so that the cutting die 120 is first positioned on the mounting foot 112, and then the locking piece 160 is locked, so that the cutting die 120 is fixed to the mounting foot 112 by the locking piece 160. Since the moving member 130 is fixedly mounted on the front side of the mounting plate 111 , a larger operating space can be provided to facilitate the removal and replacement of the suction device 140 .

Please refer to FIG. 5, which is a three-dimensional schematic diagram of an object cutting and sucking system 200 according to one embodiment of the present disclosure. The object cutting and sucking system 200 includes a robot arm 210 and the above-mentioned object cutting and sucking mechanism 100. The mounting plate portion 111 of the object cutting and sucking mechanism 100 is disposed on the robot arm 210. An appropriate object cutting and sucking mechanism 100 can be selected according to the size of the object 150 to be cut. The number of object cutting and sucking mechanisms 100 disposed on the robot arm 210 can be one or more.

In the above, the robot arm 210 drives the object cutting and sucking mechanism 100 to move, as shown in FIG6A, and uses the cutting die 120 to cut out the object 150 on the sheet 220, while the sucking device 140 vacuum absorbs the object 150. Then the robot arm 210 moves the object cutting and sucking mechanism 100, as shown in FIG6B, and the object cutting and sucking mechanism 100 moves to the attachment 230 to be attached. As shown in FIG6C, the moving member 130 then drives the sucking device 140 to separate the object 150 from the cutting die 120. In other words, the sucking device 140 maintains a vacuum absorption state, and the moving member 130 drives the sucking head 143 to move along the through hole 122h of the cutting die 120, so that the sucking head 143 and the object 150 move and protrude from the through hole 122h, so that the object 150 will not stick to the cutting die 120. Then the object 150 is attached to the attachment to be attached 230. As shown in FIG6C, when the object 150 on the suction head 143 is attached to the attachment to be attached 230, the suction device 140 breaks the vacuum at the same time, so that the object 150 is separated from the suction device 140.

From the above implementation method, it can be known that one of the advantages of the present disclosure is that because the object cutting mechanism of the present disclosure has a cutting die and a suction device, when the cutting die cuts out the object, the suction device simultaneously vacuum absorbs the object, and then when the object is attached to the attachment to be attached, the suction device can break the vacuum to ensure that the object will not stick to the suction head. Therefore, there is no need to pre-cut the object and then prepare the material for placement, which can effectively prevent the objects from piling up and sticking. Therefore, the abnormal rate can be reduced and the overall utilization rate can be improved. In addition, because there is no need to pre-cut the object and then prepare the material for placement, there is no need for a work plate to provide preparation for placement, which can reduce costs.

Although the present disclosure has been disclosed as above by way of embodiments, it is not intended to limit the present disclosure. Anyone with ordinary knowledge in this technical field may make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the definition of the attached patent application scope.
