Referring to fig. 1A, 1B and 1C, a perspective view, a side view and a lower view of an object cutting and sucking mechanism 100 according to an embodiment of the invention are shown respectively. The object cutting and sucking mechanism 100 of the present invention includes a base 110, a cutting die 120, a moving member 130 and a sucking device 140. As shown in fig. 6A and 6B, the object cutting and sucking mechanism 100 is used for vacuum sucking the object 150 by the sucking device 140 in cooperation with a vacuum supply (not shown) while the cutting die 120 cuts the object 150. Wherein, the object 150 may be a heat sink pad.

As shown in fig. 1A, 1B, and 1C, the base 110 includes a mounting plate portion 111 and a plurality of mounting leg portions 112. The mounting leg portions 112 are spaced apart from each other, and the mounting leg portions 112 are provided on the end surfaces of the mounting plate portion 111. Referring to fig. 1A, the outer contour of the base 110 is substantially L-shaped. The mounting plate 111 includes a front surface and a rear surface facing each other. The mounting leg portion 112 is provided on the bottom end surface of the mounting plate portion 111, and the mounting leg portion 112 extends rearward, that is, the mounting leg portion 112 protrudes from the rear side surface of the mounting plate portion 111. Referring to fig. 2, a positioning hole 113 is formed on the bottom surface of the mounting leg 112.

As shown in fig. 1A, 1B and 1C, the cutting die 120 is disposed on the base 110, wherein the cutting die 120 spans the mounting leg 112 of the base 110. As shown in fig. 1C, the die 120 is locked to the base 110 by a locking member 160, wherein the locking member 160 may be a screw. As shown in fig. 1B, 1C and 2, the die 120 includes a substrate 121, a tool bit 122 and a positioning post 123.

As shown in fig. 1B and 2, the substrate 121 is disposed astride the mounting leg 112 of the base 110 and is positioned below the mounting plate 111. The substrate 121 has a first surface 121f and a second surface 121s opposite to each other. The first surface 121f of the substrate 121 faces the mounting leg 112 of the base 110.

As shown in fig. 2, the tool bit 122 is disposed under the substrate 121 and protrudes from the second surface 121s of the substrate 121. One end of the cutter head 122 protruding from the second surface 121s forms a perforation 122h and a cutting edge 122b. The through hole 122h penetrates the tool bit 122 and extends to the first surface 121f of the substrate 121, i.e., the through hole 122h penetrates the tool bit 122 and further penetrates the substrate 121. As shown in fig. 1C, the bottom profile of the through hole 122h may be quadrangular, square, or circular, but the shape is not limited thereto. As shown in fig. 1C, blade 122b surrounds perforation 122h. The shape of the bottom inner contour of the blade 122b may be quadrangular or square, or may be circular, but the shape is not limited thereto. In one example, the bottom outline shape of the blade 122b may match the bottom outline shape of the perforation 122h, i.e., when the bottom outline shape of the perforation 122h is quadrilateral, the bottom outline shape of the blade 122b is also quadrilateral. By matching the shapes, the vacuum adsorption accuracy and stability can be ensured in an auxiliary manner.

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 cutter die 120 is disassembled or replaced, the cutter die 120 can be rapidly positioned by utilizing the matching of the positioning column 123 and the positioning hole 113, so that the assembly convenience is improved.

As shown in fig. 1A, the moving member 130 is provided on the base 110, and in one example, the moving member 130 is provided on the front side surface of the mounting plate portion 111. In one example, the moving member 130 may employ an air cylinder. As shown in fig. 1A and 1B, the moving member 130 includes a cylinder 131, a cylinder core 132, and a moving seat 133. The cylinder 131 is fixedly arranged on the base 110. In one example, the cylinder 131 is fixed to the front surface of the mounting plate 111. As shown in fig. 1A, the cylinder 132 is provided to the cylinder 131, and one end of the cylinder 132 protrudes from the cylinder 131. The cylinder 132 is moved relative to the cylinder 131 by changing the direction of the gas flowing into and out of the cylinder 131, i.e., the cylinder 132 can move up and down relative to the cylinder 131 as seen in the orientation shown in fig. 1A.

As shown in fig. 1A and 1B, the moving seat 133 is disposed at the bottom end of the cylinder 132, i.e., the moving seat 133 is disposed in the cylinder 132 and protrudes from one end of the cylinder 131. The moving seat 133 moves with the cylinder 132. In other words, the moving seat 133 moves with the cylinder 132. Therefore, when the cylinder core 132 moves relative to the cylinder 131, the moving seat 133 also moves relative to the cylinder 131. In one example, the movable base 133 may have an L-shape. The moving seat 133 includes an assembling portion 1331 and a guiding arm 1332. The fitting portion 1331 is provided in the cylinder core 132 and protrudes out of one end of the cylinder 131. As shown in fig. 1A, an assembling portion 1331 is provided at the bottom end of the cylinder core 132, and the assembling portion 1331 is located below the cylinder block 131. The guide arm 1332 is provided on the fitting portion 1331. As shown in fig. 1A, a guide arm 1332 is provided at the left end edge of the fitting portion 1331, and the guide arm 1332 extends upward. The inner side surface of the guide arm 1332 forms a protrusion 1332p, and the protrusion 1332p faces and contacts the cylinder 131. The protrusion 1332p may assist in improving the stability of the up-and-down movement of the movable base 133.

As shown in fig. 1A and 1C, the suction device 140 is disposed on the moving member 130. That is, the suction device 140 is provided on a side surface of the fitting portion 1331 of the moving seat 133 opposite to the cylinder 132, the fitting portion 1331 being located between the cylinder 131 and the suction device 140. The suction device 140 protrudes into the cutter mold 120, and the suction device 140 moves relative to the cutter mold 120 by the moving member 130. That is, the suction device 140 moves with the moving base 133, and the portion of the suction device 140 extending into the cutter mold 120 can move along the through hole 122 h. The suction device 140 may be connected to a vacuum supply member, and performs vacuum suction operation in cooperation with the vacuum supply member. The vacuum supply may be, for example, a vacuum pump. The suction means 140 may further perform a vacuum breaking operation. As shown in fig. 1A, 2 and 3, the suction device 140 includes a connecting base 141, a connecting 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 and the moving seat 133 move together. As shown in fig. 1B, when the cylinder 132 drives the moving base 133 to move up and down, the connecting base 141 also moves up and down along with the moving base 133. In other words, the moving member 130 can drive the connecting seat 141 of the suction device 140. The connection seat 141 is located between the mounting leg portions 112, and the connection seat 141 is located between the mounting plate portion 111 and the die 120. The portion of the connecting seat 141 extending laterally beyond the mounting plate 111 is fixed to the movable seat 133, so as to facilitate the operation of mounting and dismounting the connecting seat 141 to and from the movable seat 133.

The connector 142 is disposed on the connecting seat 141 and connected to the vacuum supply member. As shown in fig. 1A, the connection head 142 is provided at a portion of the connection seat 141 extending laterally beyond the mounting plate portion 111, that is, the connection head 142 is provided at a front end surface of the connection seat 141.

As shown in fig. 1C, 2 and 3, the suction head 143 is slidably engaged with the through hole 122h, i.e., the engagement degree of the suction head 143 in the through hole 122h, which moves smoothly along an axial direction of the die 120. As shown in fig. 1C and 4, the end face of the suction head 143 forms a through hole 143h, i.e., the through hole 143h is formed in the suction head 143 at the end face adjacent to the blade 122 b. In one example, the through holes 143h are arranged in a matrix on the tip end surface of the suction head 143. In one example, the partial through holes 143h are adjacent to the outer edge of the suction head 143 and are arranged at intervals from each other, further enclosing an area. The remaining through holes 143h are located in this area, adjacent to the center of the end face of the suction head 143. The vacuum suction force is more uniformly distributed by the distribution configuration of the through holes 143h.

As shown in fig. 4, 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 face of the suction head 143 and are arranged at intervals from each other. The size of the bumps 143p may be the same or different. Grooves 143g are formed in the distal end face of the suction head 143, wherein these grooves 143g surround the bumps 143p and communicate with the through holes 143h. A ring wall 143w is formed at the end face of the suction head 143 and surrounds the groove 143g. The annular wall 143w is flush with the bump 143p, i.e., the end face of the annular wall 143w is flush with the end face of the bump 143 p. By the arrangement of the grooves 143g and the bumps 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 may be a member made of a polyetheretherketone material. By selecting appropriate materials, the adhesion strength of the object 150 to the suction head 143 can be reduced.

A flow passage 144 is formed in the suction device 140. Wherein the runner 144 extends the connector 142 and the connecting seat 141, and the runner 144 communicates with the vacuum supply and the through hole 143h. The inner diameter of the flow passage 144 may be equal or unequal.

The cutting die 120 with proper size can be detached and replaced according to the size of the object 150 to be cut, and the suction device 140 matched with the cutting die 120 is detached and replaced together. In the replacement operation, the lock 160 is removed, and the die 120 is removed from the mounting leg 112. The suction device 140 is then detached from the moving member 130. The suction device 140 to be mounted is then mounted on the mounting portion 1331 of the movable base 133. The die 120 to be mounted is inserted into the positioning hole 113 of the mounting foot 112 by the positioning post 123, so that the die 120 is positioned on the mounting foot 112, and then locked into the locking piece 160, so that the die 120 is fixed on the mounting foot 112 by the locking piece 160. Since the moving member 130 is fixedly disposed on the front side surface of the mounting plate portion 111, a large operation space can be provided to facilitate the replacement of the suction device 140.

Referring to fig. 5, a schematic perspective view of an object cutting and sucking system 200 according to an embodiment of the invention is shown. The object cutting and sucking system 200 includes a robot arm 210 and the object cutting and sucking mechanism 100. The mounting plate 111 of the object cutting and sucking mechanism 100 is provided on the robot arm 210. The appropriate article cutting suction mechanism 100 may be selected according to the size of the article 150 to be cut. The number of the object cutting and sucking mechanisms 100 provided on the robot arm 210 may be one or more.

In the above description, the robot arm 210 drives the object cutting and sucking mechanism 100 to move, as shown in fig. 6A, to cut the object 150 on the sheet 220 by using the cutting die 120, and the sucking device 140 vacuum sucks the object 150. Then, the robot 210 moves the object cutting and sucking mechanism 100, as shown in fig. 6B, the object cutting and sucking mechanism 100 moves onto the accessory 230 to be attached. As shown in fig. 6C, the moving member 130 drives the suction device 140 to separate the object 150 from the die 120. In other words, the suction device 140 keeps the vacuum suction state, and the moving member 130 drives the suction head 143 to move along the through hole 122h of the die 120, so that the suction head 143 and the object 150 move to protrude out of the through hole 122h, and the object 150 is not adhered to the die 120. The object 150 is then attached to the attachment 230. As shown in fig. 6C, when the object 150 on the suction head 143 is attached to the attachment 230, the suction device 140 breaks the vacuum, so that the object 150 is separated from the suction device 140.

In the above embodiment, the object cutting mechanism of the present invention has a cutting die and a suction device, wherein the suction device simultaneously vacuum-sucks the object when the cutting die cuts the object, and then the suction device breaks vacuum when the object is attached to the accessory to be attached, so as to ensure that the object is not stuck on the suction head. Therefore, the situation that the objects are stacked and stuck can be effectively prevented without pre-cutting the objects and placing the spare materials. Therefore, the abnormality rate can be reduced and the overall utilization rate can be improved. In addition, since the object to be cut is not required to be placed after the stock, the work plate is not required to be placed after the stock is cut, and the cost can be reduced.

Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited thereto, and that various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the present invention, and the scope of the present invention is defined by the appended claims.
