In the process of clamping materials, the first return original is compressed by the two actuators, and the second return original is compressed by the driving member. Therefore, when the positive pressure airflow is lost in the execution chamber, the rebound of the first return original and the second return original causes the driving member and the two actuators to return to their original positions synchronously, thereby releasing the electronic components. The material can be clamped again by introducing positive pressure airflow into the execution chamber again. In the embodiment of the present application, the connection between the driving member and the execution chamber is optimized, and part of the driving member is set to cooperate with the execution chamber. The friction generated by the driving member sliding in the execution chamber during use is reduced without affecting the sliding of the driving member. The reduction in friction can make the return to the original position faster, and then cooperate with the first return to the original position and the second return to the original position to achieve rapid response (i.e. clamping and releasing).

[0032] Reference Figures 1 to 5 The material retrieving device 200 of the embodiment of the present application includes a mounting seat 210 , two executing members 220 and a driving member 260 .

[0033] In which, the mounting seat 210 includes a first channel 215 and an execution chamber 211 that are interconnected, the first channel 215 extends from one end of the mounting seat 210 to the border with the execution chamber 211, and the execution chamber 211 extends to the other end of the mounting seat 210, wherein the width of the first channel 215 is less than one-quarter of the width of the execution chamber 211.

[0034] The two actuators 220 are slidably mounted on the same end of the mounting base 210. The docking position of the two actuators 220 can be the position of the central axis of the actuator chamber 211, and a first return element 280 is disposed between the two actuators 220. It should be noted that in the embodiment of the present application, the movement direction of the two actuators 220 is perpendicular to the setting direction of the actuator chamber 211. In a preferred embodiment, each actuator 220 is detachably connected to a chuck 230. When the two actuators 220 approach each other, the two chucks 230 can clamp the electronic component 400 located between the two chucks 230. The chuck 230 is generally detachably connected to the actuator 220 via a screw 250. The chuck 230 can be designed accordingly according to different electronic components 400. Different electronic components 400 generally have different chucks 230. Therefore, when clamping corresponding materials, the corresponding chuck 230 should be replaced.

[0035] The driving member 260 is arranged in the execution chamber 211. Part of the driving member 260 is in clearance with the wall of the execution chamber 211. That is, the driving member 260 can slide along the setting direction of the execution chamber 211. A second return member 271 is provided between the driving member 260 and the mounting seat 210. The second return member 271 is used to return the execution member 220 to its original position. Under normal conditions, Figure 2 and Figure 4 As shown, the end of the driving member 260 is against the end of the execution chamber 211 connected to the first channel 215, and the end of the driving member 260 away from the first channel 215 is connected to the actuator 220 through a transmission structure. When the driving member 260 moves toward the position between the two actuators 220 under the action of external force, the two actuators 220 can approach each other and put the first return original member 280 into a compressed state, and put the second return original member 271 into a compressed state.

[0036] When the material picking device 200 of the present application is used to clamp the material, a positive pressure airflow is introduced into the first channel 215. After the positive pressure airflow enters the execution chamber 211, it pushes the driving member 260 to move toward the position between the two execution members 220. Because the driving member 260 and the execution member 220 are connected by a transmission structure, the linear motion of the driving member 260 can be converted into the movement of the two execution members 220 to move toward each other. By closing the two execution members 220 toward each other, the chuck 230 can move the material between the two execution members 220. The electronic component 400 in the middle of the chuck 230 is clamped. During the material clamping process, the first return original part 280 is compressed by the two executive parts 220, and the second return original part 271 is compressed by the driving part 260. Therefore, when the positive pressure airflow is lost in the execution chamber 211, the rebound of the first return original part 280 and the second return original part 271 causes the driving part 260 and the two executive parts 220 to return to their original positions synchronously, thereby releasing the electronic component 400. The positive pressure airflow is then introduced into the execution chamber 211 again to clamp the material again. In the embodiment of the present application, the connection between the driving part 260 and the execution chamber 211 is optimized, and a portion of the driving part 260 is configured to cooperate with the execution chamber 211. Without affecting the sliding of the driving part 260, the friction generated by the sliding of the driving part 260 in the execution chamber 211 during use is reduced. The reduction in friction can make the return to the original position faster, and then cooperate with the first return original part 280 and the second return original part 271 to achieve rapid response (i.e., clamping and releasing).

[0037] Further, such as Figure 8 and Figure 9 As shown, the driving member 260 includes a first cylinder and a second cylinder 261 connected to each other. The outer diameter of the second cylinder 261 is loosely matched with the execution chamber 211, and the ratio of the length of the second cylinder 261 to the length of the execution chamber 211 is set to 0.2 to 0.35. Specifically, a step is formed at the connection between the first cylinder and the second cylinder 261. The second cylinder 261 with a larger diameter is adapted to the execution chamber 211 so that the driving member 260 can slide along the setting direction of the execution chamber 211. By controlling the contact area between the second cylinder 261 and the execution chamber 211, the friction of the driving member 260 sliding in the execution chamber 211 is reduced while achieving normal sliding of the driving member 260, thereby making the sliding of the driving member 260 smoother.

[0038] In some embodiments, a guide ring 272 is provided at one end of the execution chamber 211 away from the first channel 215, and the first cylinder fits into the inner ring of the guide ring 272. Because the contact area between the driver 260 and the execution chamber 211 is reduced, the sliding contact wear of the second cylinder 261 alone is relatively large, and long-term high-frequency use is still prone to jamming or slow response. By providing a guide ring 272 at a position away from the first channel 215 in the execution chamber 211 to guide the movement of the first cylinder, and then cooperating with the second cylinder 261 to achieve two-point contact guidance, the sliding of the driver 260 is smoother, and jamming in high-frequency movement is reduced. At the same time, the contact area between the guide ring 272 and the first cylinder is effectively controlled, and the ratio of the thickness of the guide ring 272 to the first cylinder is controlled between 0.2 and 0.3. The additional guide ring 272 will not increase friction too much.

[0039] Further, such as Figure 2 and Figure 4 As shown, the second return element 271 is a spring, which is sleeved on the first cylinder. One end of the spring abuts against the second cylinder 261, and the other end abuts against the guide ring 272. The arrangement of the second return element 271 allows the driving member 260 to quickly return to the position when it is not required to work. Figure 2 and Figure 4 The initial state shown is convenient for quick operation next time.

[0040] In some embodiments, the outer surface of the guide ring 272 of the present application is loosely coupled with the wall of the actuating chamber 211. A retaining spring groove 216 is provided in the actuating chamber 211, and a retaining spring 273 is disposed within the retaining spring groove 216. The retaining spring 273 cooperates with the retaining spring groove 216 to prevent the guide ring 272 from separating from the actuating chamber 211. Furthermore, the second return element 271 is provided to ensure that the guide ring 272 always abuts against the retaining spring 273, thereby maintaining the guide ring 272 at the end of the actuating chamber 211 away from the first channel 215.

[0041] In some embodiments, a sealing ring 2611 is provided on the outer surface of the second cylinder 261. The provision of the sealing ring 2611 can prevent the positive pressure airflow entering the execution chamber 211 from leaking from the gap between the second cylinder 261 and the execution chamber 211, thereby reducing the loss of positive airflow pressure and improving the sealing effect. Figure 8 and Figure 9 As shown, a fixing groove 261 a for placing the sealing ring 2611 is opened on the outer surface of the second cylinder 261 , and the portion of the sealing ring 2611 installed in the fixing groove 261 a protrudes from the outer surface of the second cylinder 261 .

[0042] like Figure 8 and Figure 9As shown, the end of the driving member 260 away from the first channel 215 has a symmetrically arranged first inclined surface 2631 and a second inclined surface 2632, and the actuator 220 has a third inclined surface 2231 adapted to the first inclined surface 2631 or the second inclined surface 2632. The two actuators 220 are symmetrically arranged so that the third inclined surface 2231 can adapt to the first inclined surface 2631 or the second inclined surface 2632. The first inclined surface 2631, the second inclined surface 2632 and the third inclined surface 2231 are adapted to form a transmission structure. Specifically, Figure 2 and Figure 4 This is a schematic diagram of the connection between the normally installed actuator 220 and the driving member 260. Regardless of whether it is in the clamping state (that is, the driving member 260 compresses the second return member 271, and the second cylinder 261 is close to the guide ring 272) or in the normal state (the second cylinder 261 is close to the end of the actuator chamber 211 connected to the first channel 215), the first inclined surface 2631 abuts against the third inclined surface 2231 of one of the actuators 220, and the second inclined surface 2632 abuts against the third inclined surface 2231 of the other actuator 220 to form an inclined wedge structure. Because the two actuators 220 can slide, and the sliding direction of the actuator 220 is perpendicular to the sliding direction of the driving member 260, the transmission structure formed by the adaptation of the first inclined surface 2631, the second inclined surface 2632 and the third inclined surface 2231 can simultaneously drive the two actuators 220 to approach each other synchronously to complete the clamping action.

[0043] Specifically, the first inclined surface 2631 and the second inclined surface 2632 are inclined toward each other, and at least a portion of the first inclined surface 2631 or the second inclined surface 2632 abuts the third inclined surface 2231. At least a portion of the first inclined surface 2631 or the second inclined surface 2632 is located in the motion path of the third inclined surface 2231. Regardless of whether the material retrieving device 200 of the present application is in the clamping or releasing state, at least a portion of the third inclined surface 2231 is always located between the first inclined surface 2631 and the second inclined surface 2632. In other words, the driving member 260 can limit the sliding range of the actuator 220.

[0044] In the embodiment of this application, Figure 8 and Figure 9 As shown, the end of the driving member 260 has two first protrusions 263, and the two first protrusions 263 are respectively provided with a first inclined surface 2631 and a second inclined surface 2632 on the opposite sides. Figure 6 and Figure 7 As shown, the end of the actuator 220 is provided with a notch 222 to form a second convex portion 223, and the third inclined surface 2231 is provided on the groove wall of the notch 222. When the actuator 220 is slidably provided on the mounting seat 210, the driving member 260 is in a position as shown in FIG. Figure 2 and Figure 4In the normal state shown, part of the second protrusion 223 is in the execution chamber 211 and is located between the two first protrusions 263. Therefore, when the two actuators 220 move away from each other, the first protrusion 263 serves to limit the actuator 220 from separating from the mounting seat 210. That is, regardless of whether the material picking device 200 of the present application is in a clamping or releasing state, at least part of the third inclined surface 2231 is always between the first inclined surface 2631 and the second inclined surface 2632, that is, the driving member 260 can limit the sliding range of the actuator 220.

[0045] Further, such as Figure 10 and Figure 11 As shown, one end of the mounting base 210 is a docking portion 212 for docking with the outside, and the other end of the mounting base 210 is an actuator end 213. The actuator end 213 has an actuator slot 2131 extending through both sides. The actuator slot 2131 extends through the actuator cavity 211, that is, a portion of the actuator slot 2131 overlaps with the actuator cavity 211. The actuator 220 is slidably connected to the actuator slot 2131 via a guide structure. The first return element 280 is a spring, and the two ends of the spring disposed in the actuator slot 2131 respectively abut the two actuators 220. The provision of the first return element 280 allows the actuators 220 that are approaching each other to automatically return to their original positions after the external force disappears. Specifically, the ends of the actuators 220 are provided with a receiving slot 224 for positioning the first return element 280.

[0046] In the embodiment of the present application, the widths of both sides of the actuator 220 are adapted to the width of the actuator groove 2131, and the second protrusion 223 protrudes from the side of the actuator 220. Therefore, when the actuator 220 is slidably set in the actuator groove 2131 through the guide structure, the protruding part of the second protrusion 223 can enter the actuator cavity 211.

[0047] Furthermore, the guide structure includes a slide groove 221 and a slide rail 240, wherein Figure 6 and Figure 7As shown, the side of the actuator 220 has a slide groove 221, and the groove wall of the actuator groove 2131 is provided with a slide rail 240, which is removable. Specifically, the slide rail 240 is a cylindrical member extending from one end of the actuator groove 2131 to the other end. The actuator groove 2131 is provided with a groove 2132 adapted to fit the slide rail 240. When the actuator 220 is placed in the actuator groove 2131 and the second protrusion 223 is located between the two first protrusions 263, the slide rail 240 is placed between the slide groove 221 and the groove 2132. The mounting base 210 is then threadedly connected via screws 250 to prevent the slide rail 240 from being disengaged from the actuator groove 2131. Due to the interaction between the actuator 220 and the actuator groove 2131, and the interaction between the slide rail 240 and the slide groove 221, the actuator 220 can slide smoothly within the actuator groove 2131. Since the second protrusion 223 is located between the two first protrusions 263 , the two actuators 220 cannot escape from the actuator slots 2131 .

[0048] When installing the material retrieving device 200 of the present application, first install the sealing ring 2611 in the fixing groove 261a of the second cylindrical body 261, then place the actuator 220 into the actuator chamber 211, and then put the second return member 271 and the guide ring 272 into the first cylindrical body in sequence. Then, place the retaining spring 273 in the retaining spring groove 216 to limit the range of motion of the actuator 220. Then, place the two actuators 220 into the actuator groove 2131, and make the second protrusion 223 be located between the two first protrusions 263. Then, place the slide rail 240 between the slide groove 221 and the channel 2132 to limit the actuator 220 from leaving the actuator groove 2131. Then, use the screws 250 to limit the two ends of the slide rail 240 to complete the installation of the entire material retrieving device 200. It is easy to install and easy to repair and replace later.

[0049] In the embodiment of the present application, the material retrieving device 200 further includes a reference member 290, which includes a first reference portion 291 and a second reference portion 292. The first reference portion 291 includes a reference body and a connecting ear that are connected to each other. The connecting ear is fixedly connected to one side of the mounting base 210 by bolts. The reference body extends from one side of the mounting base 210 to the other side and is located between the two clamps 230. The second reference portion 292 is fixed to the other side of the mounting base 210. The end of the second reference portion 292 is connected to the reference body by bolts. The reference body plays a role in positioning the clamped material.

[0050] 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.
