Detailed implementation manners

[0029] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present invention in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components alone, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. For example, fixed connection / fixed installation can be selected from screw connection, bolt connection, pin connection, key connection, bonding, tenon and mortise connection, welding, riveting and other methods according to needs. For example, detachable connection can be selected from screw connection, bolt connection, threaded connection, snap connection, tenon and mortise connection, magic tape connection and other methods according to needs. The various technical features in the present invention can be combined with each other without conflict.

[0030] Refer to Figure 1 、 Figure 2, an embodiment of the present invention provides an adaptive suction nozzle tooling, which includes a main frame 1, a clamping device 2, a detection device 4, a collection device 3, a lifting device 5, and an adsorption device 6. Among them, the main frame 1 is used to support and fix the main structures of the remaining devices, usually made of metal or high-strength plastic, and includes a fixed frame 101 and a movable frame 102. The movable frame 102 can move relative to the fixed frame 101. The clamping device 2 is installed on the movable frame 102 to clamp the suction nozzle 701 on the negative pressure cup 7. The fixed end of the lifting device 5 is installed on the fixed frame 101, and the movable end of the lifting device 5 is connected to the movable frame 102, so as to provide the power to drive the clamping device 2 to rise / fall. The adsorption device 6 is installed on the fixed frame 101. During the process of pulling out the suction nozzle 701, the adsorption device 6 is used to adsorb on the frame of the press equipment to be pulled, preventing the overall tooling from being lifted when the self-weight of the tooling is insufficient to support the nail-pulling force during the process of clamping and pulling out the suction nozzle 701. The detection device 4 is used to detect whether the suction nozzle 701 has been successfully pulled out. The collection device 3 is used to collect the pulled-out suction nozzles 701.

[0031] In this embodiment, referring to Figure 4 , the clamping device 2 includes a support beam 201, a floating clamping mechanism 202, and a clamping driving mechanism 203. Both ends of the installation beam are fixed on the movable frame 102. There are a plurality of the floating clamping mechanisms 202 arranged in a straight line on the support beam 201 (the arrangement direction of the plurality of floating clamping mechanisms 202 is marked as the X-axis direction), so as to simultaneously pull out a plurality of suction nozzles 701 in the press equipment.

[0032] Specifically, referring to Figures 5 - 9, the floating clamping mechanism 202 includes a first-stage floating block 2021 slidably connected to the support beam 201 and two second-stage floating blocks (marked as second-stage floating block A 2022 and second-stage floating block B 2023) slidably connected to the first-stage floating block 2021. The sliding directions of the first-stage floating block 2021 and the second-stage floating blocks are both in the X-axis direction. A tongue (marked as the first tongue 2027 and the second tongue 2028) is provided on each of the two second-stage floating blocks. A clamping space for the clamping nozzle 701 is formed between the two tongues. A limiting block 2024 is provided on the first-stage floating block 2021, and the limiting block 2024 is located in the middle of the clamping space. The width of the limiting block 2024 is greater than the distance of the position deviation of the nozzle 701 (for example, if the diameter of the nozzle 701 is 10 mm and the position deviation of the nozzle 701 is 2 mm, then the width of the limiting block 2024 is greater than 14 mm). Elastic members 2025 are provided between the second-stage floating block A 2022 and the first-stage floating block 2021, and between the second-stage floating block B 2023 and the first-stage floating block 2021. The clamping driving mechanism 203 is used to drive the two second-stage floating blocks to move away from each other.

[0033] It can be understood that when pulling out the nozzle 701, the clamping driving mechanism 203 drives the second-stage floating block A 2022 and the second-stage floating block B 2023 to move away from each other, so as to open the clamping space to facilitate the nozzle 701 to enter the clamping space. Then, after the clamping driving mechanism 203 cancels the acting force on the second-stage floating block A 2022 and the second-stage floating block B 2023, under the action of the elastic member 2025, the second-stage floating block A 2022 and the second-stage floating block B 2023 move towards each other and slowly clamp the nozzle 701 to facilitate pulling out the nozzle 701. When the nozzle 701 is not at the center of the second-stage floating block A 2022 and the second-stage floating block B 2023, if the nozzle 701 is close to the side of the second-stage floating block A 2022, then the first tongue 2027 on the second-stage floating block A 2022 will first contact the nozzle 701, that is to say, the second-stage floating block A 2022 will first contact the limiting block 2024, thereby pushing the first-stage floating block 2021 to slide on the support beam 201. When the second-stage floating block B 2023 contacts the limiting block 2024, the nozzle 701 is located at the center of the second-stage floating block A 2022 and the second-stage floating block B 2023. In this way, when the lifting device 5 drives the clamping to descend, the nozzle 701 on the negative pressure cup 7 can be pulled out.

[0034] Further, referring to Figure 10 and Figure 11, two sliding positioning pins 20213 are provided on the first - stage floating block 2021, and a plurality of waist - shaped holes 2011 are provided on the support beam 2021 to correspond to the sliding positioning pins 20213 of the first - stage floating blocks 2021 in the plurality of floating clamping mechanisms 202. The sliding positioning pins 20213 are slidably connected in the waist - shaped holes 2011, so as to realize the sliding of the first - stage floating block 2021 on the support beam 2021.

[0035] Further, referring to Figure 7 , a slide rail 2026 is provided on the first - stage floating block 2021. The slide rail 2026 is connected with two sliders 2029, and the two sliders 2029 are respectively arranged on the second - stage floating block A 2022 and the second - stage floating block B 2023, so as to realize the sliding of the second - stage floating block A 2022 and the second - stage floating block B 2023 on the support beam 2021.

[0036] Further, referring to Figure 7 and Figure 8 , two first spring blocking pins (marked as the first spring blocking pin A 20212 and the first spring blocking pin B 20211) are provided on the first - stage floating block 2021. A second spring blocking pin (marked as the second spring blocking pin A 20221 and the second spring blocking pin B 20231) is respectively provided on the second - stage floating block A 2022 and the second - stage floating block B 2023. The elastic member 2025 includes a first spring and a second spring. The first spring is connected between the first spring blocking pin A 20212 and the second spring blocking pin A 20221. Thus, when the second - stage floating block A 2022 slides away from the limit block 2024, the first spring is stretched, so as to generate an elastic force that drives the second - stage floating block A 2022 to move back. The second spring is connected between the first spring blocking pin B 20211 and the second spring blocking pin B 20231. Similarly, when the second - stage floating block B 2023 slides away from the limit block 2024, the second spring is stretched, so as to generate an elastic force that drives the second - stage floating block B 2023 to move back. In this way, the second - stage floating block A 2022 and the second - stage floating block B 2023 move towards each other to clamp the suction nozzle 701.

[0037] In this embodiment, referring to Figure 5 and Figure 6, the clamping drive mechanism 203 includes a support plate 2031, a first moving plate 2032, a second moving plate 2033 and a linear module. The support plate 2031 is fixed to the bottom of the support beam 201. The first moving plate 2032 is slidably connected to the support plate 2031 in the X-axis direction through a first linear guide rail 2040. The second moving plate 2033 is slidably connected to the support plate 2031 in the X-axis direction through a second linear guide rail 2041. And the first moving plate 2032 is located below the second moving plate 2033. A plurality of first connection blocks 2034 are arranged on the first moving plate 2032. The plurality of first connection blocks 2034 are respectively connected to the secondary floating blocks A 2022 in the plurality of floating clamping mechanisms 202. A plurality of second connection blocks 2035 are arranged on the second moving plate 2033. The plurality of second connection blocks 2035 are respectively connected to the secondary floating blocks B 2023 in the plurality of floating clamping mechanisms 202. Specifically, the first connection block 2034 and the second connection block 2035 are located between the secondary floating block A 2022 and the secondary floating block B 2023, that is, the first connection block 2034 forms a limit with the secondary floating block A 2022 in the moving direction, and the second connection block 2035 forms a limit with the secondary floating block B 2023 in the moving direction. The linear module is used to drive the first moving plate 2032 and the second moving plate 2033 to move alternately.

[0038] It can be understood that when the linear module drives the first moving plate 2032 to move leftward and drives the second moving plate 2033 to move rightward, the first connection block 2034 moves leftward to push the second spring blocking pin A 20221 on the secondary floating block A 2022 to move leftward, and the second connection block 2035 moves rightward to push the second spring blocking pin B 20231 on the secondary floating block B 2023 to move rightward, so that the secondary floating block A 2022 and the secondary floating block B 2023 move away from each other, so as to open the clamping space between the first tongue piece 2027 and the second tongue piece 2028. And when the linear module drives the first moving plate 2032 to move rightward and drives the second moving plate 2033 to move leftward, the acting forces of the first connection block 2034 and the second connection block 2035 on the second spring blocking pin A 20221 and the second spring blocking pin B 20231 are cancelled, so that under the restoring elastic forces of the first spring and the second spring, the secondary floating block A 2022 and the secondary floating block B 2023 are driven to move toward each other, and the first tongue piece 2027 and the second tongue piece 2028 clamp the suction nozzle 701.

[0039] Further, referring to Figure 5 and Figure 6, the linear module includes a first motor 2036 and a lead screw installed on the support plate 2031. The lead screw includes a bidirectional lead screw 2037, and a first nut 2038 and a second nut 2039 respectively connected to the left-handed thread and the right-handed thread of the bidirectional lead screw 2037. The first nut 2038 and the second nut 2039 are respectively connected to the first moving plate 2032 and the second moving plate 2033, so as to drive the first moving plate 2032 and the second moving plate 2033 to move staggeredly when the first motor 2036 rotates forward and reversely.

[0040] In this embodiment, referring to Figure 2 , the lifting device 5 includes a second motor 501 and four screw jacks 504. The four screw jacks 504 are respectively arranged at the four corners of the main body frame 1. The fixed part of the screw jack 504 is installed on the fixed frame 101, and the output part of the screw jack 504 is installed on the movable frame 102. A driving sprocket 502 is arranged on the main shaft of the second motor 501, and a driven sprocket 505 is arranged on the lead screw of the screw jack 504. The driving sprocket 502 and the driven sprocket 505 are connected by a chain 503, so as to drive the four screw jacks 504 to run synchronously through the second motor 501, so as to stably drive the clamping device 2 to lift.

[0041] In this embodiment, referring to Figure 3 and Figure 4 , the collecting device 3 includes a receiving box 301 and connecting plates 302 arranged at both ends of the receiving box 301. The receiving box 301 is located directly below the clamping space. The connecting plates 302 are detachably connected to the movable frame 102 through locking bolts 303, so that after a certain number of suction nozzles 701 are collected in the receiving box 301, the receiving box 301 can be removed to recycle the suction nozzles 701.

[0042] In this embodiment, referring to Figure 2 and Figure 4 , the detection device 4 includes an opposed sensor. The transmitting end 401 and the receiving end 402 of the opposed sensor are respectively installed on both sides of the support beam 201. When the opposed sensor detects the suction nozzle 701, it means that the suction nozzle 701 has not been completely pulled out, and the work of pulling the suction nozzle 701 needs to be carried out again.

[0043] In this embodiment, referring to Figure 2 , the adsorption device 6 includes an electromagnet 601 arranged at the bottom of the fixed frame 101, and the adsorption fixation / separation of the tooling and the press lifting frame is controlled by the energization and de-energization of the electromagnet 601.

[0044] In this embodiment, referring to Figure 2, an electric control board 8 is provided on the fixing frame 101, and the operation of the first motor 2036 and the second motor 501 and the on / off of the electromagnet 601 are controlled through the electric control board 8.

[0045] The usage steps of the adaptive suction nozzle 701 tooling of the present invention are as follows:

[0046] 1. After the tooling is placed in the press of the forming equipment, the lifting frame of the press moves upward from the bottom of the press until it contacts the bottom plate of the fixing frame 101 and the electromagnet 601. The electromagnet 601 is energized to adsorb the lifting frame together, connecting the tooling and the lifting frame together, and the two move upward together and stop at the specified position.

[0047] 2. The second motor 501 operates to drive the clamping device 2 to rise (at this time, the clamping space of the floating clamping mechanism is in an open state). When the top of the floating clamping mechanism reaches the clamping height of the suction nozzle 701 (the suction nozzle 701 is located in the clamping space), the lifting device 5 stops driving the clamping device 2 to rise.

[0048] 3. The first motor 2036 operates to drive the first moving plate 2032 to move to the right and drive the second moving plate 2033 to move to the left. Under the restoring elastic force of the first spring and the second spring, the secondary floating block A2022 and the secondary floating block B2023 move towards each other, slowly clamping the first tongue piece 2027 and the second tongue piece 2028. When the suction nozzle 701 is not at the center of the first tongue piece 2027 and the second tongue piece 2028, the secondary floating block A2022 and the secondary floating block B2023 move on the primary floating block 2021. When moving to contact the limit block 2024, it forces the primary floating block 2021 to move on the support beam 201, ultimately ensuring that the suction nozzle 701 is at the center of the first tongue piece 2027 and the second tongue piece 2028.

[0049] 4. The second motor 501 operates to drive the clamping device 2 to descend and pull out the suction nozzle 701.

[0050] 5. The first motor 2036 operates to drive the first moving plate 2032 to move to the left and drive the second moving plate 2033 to move to the right, causing the secondary floating block A2022 and the secondary floating block B2023 to move away from each other, opening the clamping space of the first tongue piece 2027 and the second tongue piece 2028, and the suction nozzle 701 falls into the receiving box 301.

[0051] 6. The second motor 501 operates again to drive the clamping device 2 to rise to the detection position. When the through-beam sensor detects the suction nozzle 701, it means that the suction nozzle 701 has not been completely pulled out at one time. Repeat steps 3, 4, 5, and 6 until all the suction nozzles 701 are pulled out.

[0052] 7. The lifting frame of the press descends, the electromagnet 601 is de-energized, and the tooling is taken out to complete the operation of pulling out the suction nozzle 701.

[0053] The above is a specific description of the preferred embodiment of the present invention. However, the present invention is not limited to the described embodiment.
