[0082] The embodiments of the present application are described below in detail with reference to the accompanying drawings. The same or similar components are denoted by the same or similar reference numerals throughout the drawings, and repeated description is omitted. The embodiments described below are merely examples for explaining the present application, and should not be construed as limiting the present application.

[0083] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are merely for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application.

[0084] In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implying the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0085] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0086] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0087] like Figure 1 As shown, a Cartesian coordinate system is established, defining the length direction of the plate-stirring machine 1000 as parallel to the direction indicated by the x-axis, the width direction of the plate-stirring machine 1000 as parallel to the direction indicated by the y-axis, and the height direction of the plate-stirring machine 1000 as parallel to the direction indicated by the z-axis. It should be understood that the above definitions are merely for facilitating the understanding of the relative positional relationships of the various components of the plate-stirring machine 1000 and should not be construed as limiting the present application.

[0088] like Figure 1 and Figure 2 As shown, an embodiment provides a staggering machine 1000 that can be used in the production and processing of PCBAs in electronic products. Specifically, a PCB 2000 used to make a PCBA can be staggered in a furnace fixture 3000 for subsequent insertion, welding, and other operations.

[0089] like Figure 1 and Figure 2 As shown, the plate placing machine 1000 may include a frame 100 , a lifting unit 200 , a material transfer robot arm 300 , a button unit 400 and a reflow unit 500 .

[0090] Combined together Figure 3The lifting unit 200 can be installed in the frame 100 and positioned near an angle of the frame 100. The lifting unit 200 can include a first end 201 and a second end 202 arranged along a lifting direction. The lifting unit 200 can be used to transport the furnace jig 3000 from the first end 201 to the second end 202. The lifting direction can be parallel to the height direction of the plate-stirring machine 1000. The first end 201 can be positioned near the ground side of the frame 100, and the second end 202 can be positioned near the ground side of the frame 100.

[0091] The material transfer robot 300 can be mounted on the far side of the frame 100 and located on one side of the lifting unit 200. The material transfer robot 300 can be used to grab a PCB 2000 from the PCB pick-up position and place the grabbed PCB 2000 into a corresponding acupoint of the furnace jig 3000, where the furnace jig 3000 is located at the top of the lifting unit 200, i.e., the second end 202.

[0092] The latch unit 400 can be mounted on the frame 100. The latch unit 400 can be located on one side of the lifting unit 200 and connected to the second end 202 of the lifting unit 200. The latch unit 400 can be used to receive the furnace jig 3000 output by the lifting unit 200. During operation, the latch unit 400 can be used to activate the latch on the furnace jig 3000 to secure the PCB 2000 to the furnace jig 3000.

[0093] The reflow unit 500 can be disposed on one side of the frame 100. One end of the reflow unit 500 can be connected to the first end 201 of the lifting unit 200. The end of the reflow unit 500 away from the lifting unit 200 can be connected to a panel removal station to receive the reflowed furnace fixture 3000.

[0094] During operation, the reflow unit 500 can transport the empty furnace jig 3000 from the board removal station to the first end 201 of the lifting unit 200. The lifting unit 200 can move the furnace jig 3000 from the first end 201 to the second end 202. The material transfer robot 300 can grab the separated PCB 2000 from the PCB material picking position, and place the PCB 2000 in the corresponding acupuncture point of the furnace jig 3000 located at the second end 202. When a certain number of PCBs 2000 are placed in the furnace jig 3000, that is, when the furnace jig 3000 located at the second end 202 is full of PCBs 2000, it can be transported to the button unit 400. The button unit 400 can move the buckle on the furnace jig 3000 to fix the PCB 2000 on the furnace jig 3000. The furnace jig 3000 can then be transported to the next workstation, such as the insertion station, via a transport robot or other structure. It will be appreciated that after the insertion of the PCB 2000, it can be transported along with the furnace jig 3000 into a wave soldering furnace or selective wave soldering machine for soldering, thereby producing the corresponding PCBA. The PCBA can then be removed from the furnace jig 3000, and the empty furnace jig 3000 can be returned to the lifting unit 200 via the reflow unit 500.

[0095] The present invention provides a tray placement machine 1000 that can automatically place PCBs 2000. This improves the efficiency of PCB placement and production efficiency. Furthermore, it reduces the occurrence of component collisions during manual placement, improving product yield and reducing material loss.

[0096] Furthermore, the plate-swinging machine 1000 further includes a controller (not shown), which can be electrically connected to other electrical components in the plate-swinging machine 1000. Thus, the controller can uniformly control the operation of other electrical components in the plate-swinging machine 1000.

[0097] like Figures 3 to 5 As shown, the lifting unit 200 may include a first lifting mechanism 210 , a second lifting mechanism 220 , a plurality of first support bars 231 , and a plurality of second support bars 232 .

[0098] The first lifting mechanism 210 may be spaced apart from and opposite to the second lifting mechanism 220. A plurality of first support bars 231 may be connected to the first lifting mechanism 210, and the first lifting mechanism 210 may be configured to drive the plurality of first support bars 231 to circulate between the first end 201 and the second end 202. A plurality of second support bars 232 may be connected to the second lifting mechanism 220, and the second lifting mechanism 220 may be configured to drive the plurality of second support bars 232 to circulate between the first end 201 and the second end 202. In this embodiment, the plurality of first support bars 231 on the side of the first lifting mechanism 210 near the second lifting mechanism 220 may correspond one-to-one with the plurality of second support bars 232 on the side of the second lifting mechanism 220 near the first lifting mechanism 210, and may cooperate to support the furnace jig 3000, thereby driving the furnace jig 3000 to move from the first end 201 to the second end 202, thereby transporting the furnace jig 3000.

[0099] In some embodiments, the first lifting mechanism 210 may include a first mounting frame 212 , a lifting chain 213 , and a first driving member 211 .

[0100] The first mounting bracket 212 can extend from the first end 201 to the second end 202. The first mounting bracket 212 can be slidably mounted on the frame 100. Specifically, the lifting unit 200 also includes two sets of adapter mechanisms 240 to enable the first mounting bracket 212 to be slidably mounted on the frame 100. The two sets of adapter mechanisms 240 can be located on either side of the first mounting bracket 212.

[0101] The transfer mechanism 240 may include a fixed frame 241, a first guide rail 242, a first sliding seat 243, and a second driving member 244. One side of the fixed frame 241 may be fixedly connected to the distal side of the frame 100 and may extend toward the proximal side of the frame 100. Furthermore, one end of the fixed frame 241 may be fixedly connected to the second lifting mechanism 220, and the other end of the fixed frame 241 may extend to the position of the first lifting mechanism 210.

[0102] The first guide rail 242 can be fixedly connected to the fixed frame 241 and can extend from the first lifting mechanism 210 toward the second lifting mechanism 220. In other words, the first guide rail 242 can be parallel to the width of the plate wrangling machine 1000. The first mounting frame 212 of the first lifting mechanism 210 can be slidably connected to the first guide rail 242 via a first sliding seat 243 and can move along the first guide rail 242.

[0103] The second driving member 244 can be mounted on an end of the fixing frame 241 near the second lifting mechanism 220. In some embodiments, the second driving member 244 can be a motor. The second driving member 244 can be connected to the first sliding seat 243 via a first screw rod 245. It is understood that the first screw rod 245 can be inserted through the first sliding seat 243 and screwed to the first sliding seat 243. When the second driving member 244 drives the first screw rod 245 to rotate, it can drive the first sliding seat 243 to move the first mounting frame 212 along the first guide rail 242, thereby moving the first mounting frame 212 of the first lifting mechanism 210 closer to or farther away from the second lifting mechanism 220.

[0104] In other embodiments, the second driving member 244 may also be a cylinder or an electric push rod. The first sliding seat 243 may be fixedly connected to the output shaft of the second driving member 244 and may be driven by the second driving member 244 to move along the first guide rail 242.

[0105] In the embodiment, among the two transfer mechanisms 240 , one or two transfer mechanisms 240 may include a second driving member 244 and a first screw rod 245 .

[0106] The first lifting mechanism 210 may include two lifting chains 213. The two lifting chains 213 may be located on either side of the first mounting frame 212 along the length of the plate-stirring machine 1000. In this embodiment, the lifting chains 213 may extend from a first end 201 to a second end 202, and both ends of the lifting chains 213 may be rotatably mounted to the first mounting frame 212 via sprockets. Furthermore, the sprockets connected to the two lifting chains 213 at the same end of the lifting unit 200 may be connected via a drive shaft, enabling synchronized operation of the two lifting chains 213.

[0107] In some embodiments, the first driving member 211 can be a motor. The first driving member 211 can be fixedly mounted on an end of the first mounting frame 212 near the first end 201. The output shaft of the first driving member 211 can be drivingly connected to a sprocket near the first end 201. This sprocket can be the sprocket connected to the lifting chains 213. Thus, the first driving member 211 can drive the two lifting chains 213 to circulate between the first end 201 and the second end 202.

[0108] Multiple first support bars 231 can be connected between the two lifting chains 213 at intervals along the lifting direction. It is understood that the two ends of the first support bars 231 can be fixedly connected to the two lifting chains 213 in a one-to-one correspondence. The first support bars 231 can also be always parallel to the length direction of the plate-stirring machine 1000.

[0109] In this embodiment, the structure of the second lifting mechanism 220 can be similar to that of the first lifting mechanism 210. Specifically, the first mounting bracket 212 of the second lifting mechanism 220 can be fixedly mounted on the frame 100 to maintain a fixed position of the second lifting mechanism 220. The second support bar 232 can be fixedly connected to the two lifting chains 213 of the second lifting mechanism 220.

[0110] In the embodiment, the first lifting mechanism 210 is slidably installed on the frame 100. The position of the first lifting mechanism 210 on the frame 100 can be adjusted to adjust the distance between the first lifting mechanism 210 and the second lifting mechanism 220, and then the distance between the first support bar 231 and the second support bar 232 can be adjusted. The distance between the first support bar 231 and the second support bar 232 can be adapted to different sizes of furnace jigs 3000, thereby improving the versatility of the plate placing machine 1000.

[0111] In other embodiments, the second lifting mechanism 220 can also be slidably installed on the frame 100, and can be moved closer to or away from the first lifting mechanism 210 to adjust the distance between the first support bar 231 and the second support bar 232, and can adapt to furnace fixtures 3000 of different sizes.

[0112] like Figure 3 and Figure 5 As shown, in some embodiments, the first lifting mechanism 210 further includes a sixth driving member 214 and a first conveyor chain 215. Both ends of the first conveyor chain 215 can be rotatably mounted to the end of the first mounting frame 212 near the first end 201 via sprockets. The first conveyor chain 215 can be located on a side of the first mounting frame 212 near the second lifting mechanism 220. Furthermore, the first conveyor chain 215 can extend parallel to the length of the plate-wrap machine 1000. One end of the first conveyor chain 215 can be connected to the reflow unit 500.

[0113] In some embodiments, the sixth drive member 214 can be a motor. The sixth drive member 214 can be fixedly mounted on a side of the first mounting frame 212 away from the second lifting mechanism 220, and the output shaft of the sixth drive member 214 can be connected to a sprocket at one end of the first conveyor chain 215. Thus, the sixth drive member 214 can drive the first conveyor chain 215.

[0114] In addition, the second lifting mechanism 220 may also include a sixth driving member 214 and a first conveying chain 215. The arrangement of the sixth driving member 214 and the first conveying chain 215 in the second lifting mechanism 220 may be similar to the arrangement of the sixth driving member 214 and the first conveying chain 215 in the first lifting mechanism 210, and will not be repeated here.

[0115] like Figure 5As shown, the lifting unit 200 further includes a third sensor 271 and a fourth sensor 272. The third sensor 271 can be mounted on the first mounting bracket 212 of the second lifting mechanism 220, near the first end, and is located on a side of the first mounting bracket 212 near the first lifting mechanism 210, and also on a side of the first mounting bracket 212 near the reflow unit 500. The third sensor 271 can be used to detect whether a jig 3000 has entered the lifting unit 200.

[0116] The fourth sensor 272 can be mounted on an end of the first mounting frame 212 of the second lifting mechanism 220 that is close to the first end. The fourth sensor 272 is located on a side of the first mounting frame 212 that is close to the first lifting mechanism 210 and on a side of the first mounting frame 212 that is away from the reflow unit 500. The fourth sensor 272 can be used to detect whether the furnace jig 3000 conveyed by the first conveyor chain 215 is in place.

[0117] In some embodiments, the third sensing element 271 and the fourth sensing element 272 may be a photoelectric sensor or a Hall sensor.

[0118] When the reflow unit 500 delivers the reflowed jig 3000 to the lifting unit 200 and the third sensor 271 detects the jig 3000's arrival at the lifting unit 200, it sends a corresponding sensing signal to the controller, which in turn activates the sixth driver 214 to drive the first conveyor chain 215, thereby gradually moving the jig 3000 into the lifting unit 200. When the fourth sensor 272 detects the jig 3000, the controller deactivates the sixth driver 214. Subsequently, when the two lifting mechanisms are activated, a set of first and second support bars 231, 232 cooperate to lift the jig 3000, while another set of first and second support bars 231, 232 is positioned at the first end 201, ready to receive the next jig 3000. Furthermore, the jig 3000 gradually rises toward the second end 202 under the coordinated action of the two lifting mechanisms. It can be understood that when the first conveying chain 215 is running, the two lifting mechanisms stop running.

[0119] like Figure 3 、 Figures 5 to 7 As shown, the lifting unit 200 further includes a positioning assembly 250. In some embodiments, the positioning assembly 250 can be installed at an end of the second lifting mechanism 220 close to the second end 202 and located on a side of the second lifting mechanism 220 close to the first lifting mechanism 210.

[0120] The positioning assembly 250 may include a pneumatic hook 251, a third driving member 252 and a pushing block 253. The pneumatic hook 251 may be fixedly mounted on a side of the first mounting frame 212 in the second lifting mechanism 220 close to the first lifting mechanism 210, and the pneumatic hook 251 may be located on a side of the first mounting frame 212 away from the button unit 400. The hook of the pneumatic hook 251 may be set away from the first end 201 and toward the other side of the first mounting frame 212. During use, the pneumatic hook 251 can be used to pull the furnace jig 3000 to move along the first direction and move in a direction away from the button unit 400 to achieve side positioning in the first direction. The first direction may be parallel to the length direction of the plate setting machine 1000.

[0121] The push block 253 is slidably mounted on the end of the first mounting frame 212 of the second lifting mechanism 220 near the second end 202, and the sliding direction of the push block 253 can be parallel to the second direction. The second direction can be parallel to the width of the plate-stirring machine 1000. Furthermore, the push block 253 can be telescopically mounted relative to the side of the first mounting frame 212 near the first lifting mechanism 210. In some embodiments, the third drive member 252 can be a pneumatic cylinder. The third drive member 252 can be fixedly mounted on the first mounting frame 212, and the output shaft of the third drive member 252 can be connected to the push block 253. Thus, the third drive member 252 can drive the push block 253 to move in the second direction, thereby pushing the furnace jig 3000 in the second direction and positioning it toward the side of the first support bar 231. In this embodiment, the third drive member 252 and the push block 253 can be arranged in one, two, or three groups, as needed.

[0122] In other embodiments, the third driving member 252 may also be an electric push rod, a hydraulic cylinder or other structures.

[0123] In the embodiment, the positioning assembly 250 can position the furnace jig 3000 sideways in the first direction and the second direction to ensure that the subsequent furnace jig 3000 is smoothly transported to the button unit 400.

[0124] like Figure 3 、 Figure 5 and Figure 6 As shown, the lifting unit 200 further includes a pushing assembly 260. The pushing assembly 260 can be installed at one end of the second lifting mechanism 220 close to the second end 202. The pushing assembly 260 can be used to push the furnace fixture 3000 at the second end 202 toward the button unit 400.

[0125] The pusher assembly 260 may include a fourth drive member 262 and a push rod 261. The fourth drive member 262 may be mounted on the side of the first mounting frame 212 of the second lifting mechanism 220 that is away from the first lifting mechanism 210. In some embodiments, the fourth drive member 262 may be a linear cylinder, and the sliding block of the fourth drive member 262 may slide parallel to the length of the plate-stirring machine 1000. Its sliding axis may extend from the side of the first mounting frame 212 away from the button-pulling unit 400 to the side closer to the button-pulling unit 400. The push rod 261 may be located on the side of the second lifting mechanism 220 that is closer to the first lifting mechanism 210. One end of the push rod 261 may be fixedly connected to the sliding block of the fourth drive member 262 via a connecting frame 263, while the other end of the push rod 261 may extend toward the first lifting mechanism 210. Consequently, the fourth drive member 262 can drive the push rod 261 to move along the length of the plate-stirring machine 1000, moving it closer to or further from the button-pulling unit 400. It can be understood that when the push rod 261 pushes the furnace jig 3000 to move toward the buckle unit 400 , the furnace jig 3000 can be pushed toward the buckle unit 400 .

[0126] like Figure 2 As shown, the material transfer robot 300 can be mounted on the far side of the frame 100 and located on the side of the first lifting mechanism 210 away from the second lifting mechanism 220. In some embodiments, the material transfer robot 300 can be a three-axis robot arm, a four-axis robot arm, or a six-axis robot arm. Furthermore, the actuator end of the material transfer robot 300 can be connected to a vacuum head 310 for picking up the PCB 2000.

[0127] like Figure 2 and Figure 8 As shown, the plate-staging machine 1000 further includes a turning unit 600. The turning unit 600 can be disposed on the far side of the frame 100 and can be located on a side of the material transfer robot arm 300 away from the lifting unit 200.

[0128] When the PCB 2000 at the PCB picking position is on the reverse side and is a good product, the material transfer robot arm 300 can transfer the PCB 2000 to the flipping unit 600 for flipping, and then the material transfer robot arm 300 can send the flipped PCB 2000 to the lifting unit 200 and place it on the corresponding acupoint of the furnace fixture 3000.

[0129] It is understandable that when the PCB 2000 at the PCB picking position is at the front and is a good product, the material transfer robot 300 can directly transfer the PCB 2000 to the lifting unit 200 and place it on the corresponding acupuncture point of the furnace fixture 3000.

[0130] In some embodiments, the turning unit 600 may include a first clamping plate 611, a second clamping plate 612, and two rotary motors 620. The first clamping plate 611 and the second clamping plate 612 are spaced apart and face each other, and can cooperate to clamp the PCB 2000. Each of the first clamping plate 611 and the second clamping plate 612 is connected to a rotary motor 620. The two rotary motors 620 can operate synchronously, driving the first clamping plate 611 and the second clamping plate 612 to rotate synchronously, thereby turning the PCB 2000 over, i.e., rotating the PCB 2000 180°.

[0131] In this embodiment, the rotary motor 620 connected to the first clamping plate 611 can be slidably mounted on the frame 100 via the third mounting plate 641. The rotary motor 620 connected to the second clamping plate 612 can be fixedly mounted on the frame 100 via the fourth mounting plate 642, with the second clamping plate 612 spaced apart from the first clamping plate 611. This allows the distance between the first clamping plate 611 and the second clamping plate 612 to be adjusted to accommodate PCBs 2000 of varying sizes. Furthermore, as the first clamping plate 611 gradually approaches the second clamping plate 612, it gradually clamps the PCB 2000. As the first clamping plate 611 gradually moves away from the second clamping plate 612, it gradually releases the PCB 2000.

[0132] The turning unit 600 further includes a driving mechanism 630 for driving the third mounting plate 641 to slide relative to the frame 100. The driving mechanism 630 may include a seventh driving member 631, a second screw rod 632, a second sliding seat 633 and a second guide rail 634.

[0133] The second guide rail 634 can extend along the length of the plate-stirring machine 1000, that is, it can extend from the first clamping plate 611 to the second clamping plate 612. Two second guide rails 634 can be provided in parallel, with the two second guide rails 634 being located on either side of the first clamping plate 611. Both ends of the third mounting plate 641 can be slidably mounted to the corresponding second guide rail 634 via a second sliding seat 633.

[0134] In some embodiments, the seventh drive member 631 can be a motor. The seventh drive member 631 can be fixedly mounted on the frame 100 and located on one side of the first clamping plate 611. The output shaft of the seventh drive member 631 can be drivingly connected to the second screw rod 632. The second screw rod 632 can be arranged parallel to the second guide rail 634. The third mounting plate 641 can be connected to the second screw rod 632 via an adapter block 635, which can be threadedly connected to the second screw rod 632.

[0135] During operation, the seventh driving member 631 can drive the second screw rod 632 to rotate, and drive the third mounting plate 641 to drive the first clamping plate 611 to slide along the second guide rail 634 to move closer to or away from the second clamping plate 612 .

[0136] In other embodiments, the seventh driving member 631 may also be an electric push rod, a cylinder, etc. The output shaft of the seventh driving member 631 may be fixedly connected to the third mounting plate 641 .

[0137] In some embodiments, the tray-stirring machine 1000 further includes a recovery frame 700, which can be mounted within the frame 100. The recovery frame 700 can be positioned below the tipping unit 600 in the direction of gravity. Specifically, the opening of the recovery frame 700 can be aligned with the position between the first clamping plate 611 and the second clamping plate 612. When a defective PCB 2000 is output from the PCB pick-up position, the material transfer robot 300 can grab it, transfer it above the tipping unit 600, and release it, allowing it to fall into the recovery frame 700 for recycling.

[0138] like Figure 2 、 Figures 9 to 11 As shown, the button-pushing unit 400 may include a locking mechanism 410 and a button-pushing robot arm 420. The locking mechanism 410 may be connected to the second end 202 of the lifting unit 200. Specifically, the locking mechanism 410 may be connected to the side of the lifting unit 200 away from the pneumatic claw 251. During operation, the pushing assembly 260 in the lifting unit 200 may push the furnace jig 3000 filled with PCBs 2000 toward the locking mechanism 410. The locking mechanism 410 may be used to receive the furnace jig 3000 sent by the pushing assembly 260, and may position the PCB 2000 on the furnace jig 3000 so that the button-pushing robot arm 420 can perform the button-pushing action later.

[0139] In some embodiments, the locking mechanism 410 may include a first mounting plate 411, a second mounting plate 412, a conveying assembly 413, and a pressing assembly 414. The first mounting plate 411 and the second mounting plate 412 are spaced apart and opposed to each other. The second mounting plate 412 can be fixedly mounted on the frame 100 and is generally coplanar with the first mounting bracket 212 of the second lifting mechanism 220. The first mounting bracket 212 can be slidably mounted on the frame 100 to move closer to or further from the second mounting plate 412 to accommodate different sizes of furnace jigs 3000.

[0140] In some embodiments, the locking mechanism 410 further includes an eighth drive member 415, a third screw rod 416, and a third guide rail 417. Two third guide rails 417 may be provided. The two third guide rails 417 may be located at either end of the first mounting plate 411 along the length of the plate wrangling machine 1000. The two third guide rails 417 may be parallel to the extension direction of the first guide rail 242. The two ends of the first mounting plate 411 may be slidably mounted on the two third guide rails 417 in a one-to-one correspondence.

[0141] In some embodiments, the eighth drive member 415 can be a motor. The eighth drive member 415 can be fixedly mounted on the frame 100 and positioned near one end of the second mounting plate 412. The third screw rod 416 can be connected to the output shaft of the eighth drive member 415 and can be driven to rotate by the eighth drive member 415. Furthermore, the third screw rod 416 can be inserted through the first mounting plate 411 and threadedly connected to the first mounting plate 411. Thus, the eighth drive member 415 can drive the first mounting plate 411 to slide relative to the frame 100 as needed to adjust the distance between the first mounting plate 411 and the second mounting plate 412.

[0142] The conveyor assembly 413 may include two second conveyor chains 4132 and two ninth drive members 4131. One second conveyor chain 4132 is mounted on a side of the first mounting plate 411 near the second mounting plate 412, and is rotatable in a direction parallel to the length of the plate-stirring machine 1000. The other second conveyor chain 4132 is mounted on a side of the second mounting plate 412 near the first mounting plate 411, and is rotatable in a direction parallel to the length of the plate-stirring machine 1000.

[0143] In some embodiments, the ninth driving member 4131 can be a motor. The two ninth driving members 4131 can be connected to the two second conveying chains 4132 in a one-to-one transmission manner. The two ninth driving members 4131 can drive the two second conveying chains 4132 to operate synchronously.

[0144] A ninth driving member 4131 can be mounted on a side of the first mounting plate 411 away from the second mounting plate 412. The output shaft of the ninth driving member 4131 can extend to a side of the first mounting plate 411 close to the second mounting plate 412 and be connected to the second conveying chain 4132 on the first mounting plate 411 via a sprocket.

[0145] Another ninth driving member 4131 can be installed on the side of the second mounting plate 412 away from the first mounting plate 411. The output shaft of the ninth driving member 4131 can extend to the side of the second mounting plate 412 close to the first mounting plate 411 and be connected to the second conveying chain 4132 on the second mounting plate 412 through a sprocket.

[0146] In this embodiment, when the lifting unit 200 pushes the oven jig 3000 holding the PCB 2000 toward the detent unit 400, the conveyor assembly 413 receives the oven jig 3000 and conveys it away from the lifting unit 200. It will be appreciated that the distance between the two second conveyor chains 4132 can be adjusted by sliding the first mounting plate 411 to accommodate the size of the oven jig 3000.

[0147] In some embodiments, the locking mechanism 410 further includes a first sensing member 4191, which can be used to sense whether the lifting unit 200 pushes the furnace jig 3000 toward the button unit 400. The first sensing member 4191 can be fixedly mounted on one end of the first mounting plate 411 close to the lifting unit 200. When the first sensing member 4191 detects that the lifting unit 200 pushes the furnace jig 3000 toward the button unit 400, it can provide feedback to the controller, and the controller controls the ninth driving member 4131 to start. After the ninth driving member 4131 is started, it can drive the second conveying chain 4132 to move, thereby driving the furnace jig 3000 to move in a direction away from the lifting unit 200. In some embodiments, the first sensing member 4191 can be a photoelectric sensor or a Hall sensor.

[0148] In addition, the locking mechanism 410 also includes a second sensing member 4192. The second sensing member 4192 can be installed at the end of the first mounting plate 411 away from the lifting unit 200. The second sensing member 4192 can be used to detect whether the furnace jig 3000 has moved into place in the button unit 400. When the second sensing member 4192 senses the furnace jig 3000, it can indicate that the conveying component 413 has moved the furnace jig 3000 into place, and the sensing information can be fed back to the controller, and the controller can control the ninth driving member 4131 to stop the action. In some embodiments, the second sensing member 4192 can also be a photoelectric sensor or a Hall sensor.

[0149] In some embodiments, the locking mechanism 410 further includes a blocking cylinder 418. The blocking cylinder 418 can be mounted on the end of the locking mechanism 410 away from the lifting unit 200 and positioned near the second mounting plate 412. The blocking cylinder 418 can be used to limit the travel of the furnace jig 3000, preventing the furnace jig 3000 from moving excessively and affecting subsequent button-pulling operations.

[0150] The locking mechanism 410 may be provided with two sets of pressing components 414, which may be separately provided on the first mounting plate 411 and the second mounting plate 412. The pressing components 414 on the first mounting plate 411 are taken as an example for detailed description.

[0151] The pressing assembly 414 may include a fifth drive member 4141, an adapter plate 4142, a connecting rod 4143, and a pressing head 4144. In some embodiments, the fifth drive member 4141 may be a pneumatic cylinder. The fifth drive member 4141 may be mounted on a side of the first mounting plate 411 away from the second mounting plate 412. The output shaft of the fifth drive member 4141 may be positioned away from the frame 100 and parallel to the height of the wobble machine 1000. The adapter plate 4142 may be connected to the output shaft of the fifth drive member 4141, driving the adapter plate 4142 to move it upward or downward, toward or away from the frame 100.

[0152] One end of the connecting rod 4143 can be screwed to the adapter plate 4142. The other end of the connecting rod 4143 can extend toward the second mounting plate 412, that is, the end of the connecting rod 4143 away from the adapter plate 4142 can extend to a position between the first mounting plate 411 and the second mounting plate 412. The pressing head 4144 can be connected to the end of the connecting rod 4143 away from the adapter plate 4142 and located on the side of the connecting rod 4143 closer to the frame 100. When the fifth driving member 4141 drives the adapter plate 4142 toward the frame 100, it can drive the pressing head 4144 toward the frame 100 and press the PCB 2000 in the corresponding position against the furnace jig 3000, preventing the PCB 2000 from shaking relative to the furnace jig 3000.

[0153] In an embodiment, when the screw connected to the connecting rod 4143 is loosened, the connecting rod 4143 can be rotated relative to the adapter plate 4142, and the position of the pressing head 4144 can be adjusted to adapt to the position of the PCB 2000 on different furnace fixtures 3000.

[0154] In the embodiment, the pressing assembly 414 may include one, two, or four groups of connecting rods 4143 and pressing heads 4144 as needed. In the same group of pressing assemblies 414, all connecting rods 4143 may be connected to the same adapter plate 4142.

[0155] In other embodiments, the pressing components 414 may also be centrally arranged on the first mounting plate 411 or the second mounting plate 412. The pressing components 414 may be arranged in one group, two groups, or four groups as needed.

[0156] In an embodiment, the button-pulling robot arm 420 can be installed on one side of the locking mechanism 410. After the locking mechanism 410 presses the PCB 2000 onto the furnace jig 3000, the button-pulling robot arm 420 can be actuated to rotate the buckles on the furnace jig 3000 one by one to a certain angle, so as to fix the PCB 2000 on the furnace jig 3000, and facilitate subsequent operations such as plug-in of the PCB 2000. Among them, the button-pulling robot arm 420 can be selected from one of the structures such as a three-axis robot arm, a four-axis robot arm, a five-axis robot arm or a six-axis robot arm. It is understandable that the execution end of the button-pulling robot arm 420 can be connected to a lever 421, which can rotate the buckles on the furnace jig 3000 under the drive of the robot arm.

[0157] like Figure 1 、 Figure 3 、 Figure 12 and Figure 13As shown, the reflow unit 500 may include a conveyor belt mechanism 510, a guide plate 520, and a deflection correction plate 530. One end of the conveyor belt mechanism 510 may be connected to the first end 201 of the lifting unit 200 and may be connected to the first conveyor chain 215. The other end of the conveyor belt mechanism 510 may extend to the panel removal station to receive the removed furnace jig 3000 and transport the empty furnace jig 3000 to the lifting unit 200.

[0158] The conveyor belt mechanism 510 may include one, three, or four conveyor belt sections 511. When the conveyor belt mechanism 510 includes multiple conveyor belt sections 511, the multiple conveyor belt sections 511 may be connected sequentially. Furthermore, each conveyor belt section 511 may be equipped with a tenth drive element 512 for driving the conveyor belts 511. In some embodiments, the tenth drive element 512 may be a motor.

[0159] In some embodiments, the deflection correction plate 530 can be mounted on a side of the conveyor belt mechanism 510 and tilted relative to the conveying direction of the conveyor belt mechanism 510. Specifically, one end of the deflection correction plate 530 can be fixedly mounted on a side of the conveyor belt mechanism 510 via a fixing plate 541. The other end of the deflection correction plate 530 can extend toward the lifting unit 200 and simultaneously extend into the conveying path of the conveyor belt mechanism 510. Thus, when the furnace jig 3000 passes by, the deflection correction plate 530 can adjust and correct the placement of the furnace jig 3000, so that the furnace jig 3000 tends to be straightened.

[0160] In this embodiment, the guide plate 520 may extend generally along the conveying direction of the conveyor belt mechanism 510. Furthermore, the guide plate 520 may be located at one end of the deflection correction plate 530 near the lifting unit 200. In this embodiment, one end of the guide plate 520 may be connected to the first mounting bracket 212 of the first lifting mechanism 210 via a hinge 542. The other end of the guide plate 520 may be connected to a side edge of the conveyor belt mechanism 510 near the deflection correction plate 530 via a hinge 542.

[0161] It is understood that when the lifting unit 200 adjusts the distance between the first lifting mechanism 210 and the second lifting mechanism 220 according to the size of the furnace jig 3000, it can simultaneously drive the guide plate 520 to move closer to one end of the first lifting mechanism 210. When the furnace jig 3000 passes by the guide plate 520, the furnace jig 3000 can be guided, and the furnace jig 3000 can be gradually aligned with the lifting unit 200, so that the furnace jig 3000 can enter the lifting unit 200 smoothly.

[0162] During use, after the PCB 2000 is separated by the PCB separator at the front station, the entire PCB 2000 can be transported to the PCB material removal position so that the material transfer robot arm 300 can smoothly grab it. At the same time, the furnace jig 3000 can be gradually raised to the second end 202, i.e., the swing plate position, by the lifting unit 200, and can be positioned against the edge by the positioning component 250. Subsequently, the material transfer robot arm 300 can place the PCBs 2000 that are on the front and are good products one by one into the corresponding acupoints of the furnace jig 300 until they are full. When the PCB 2000 is on the back side, the material transfer robot arm 300 can transfer it to the flipping unit 600 to flip it over and then swing it into the furnace jig 300. If the PCB 2000 is a defective product, the material transfer robot arm 300 can send it to the recycling box 700 for recycling. Among them, the front and back of the PCB 2000 and whether it is a good product can be judged by the previous workstation and fed back to the plate placing machine 1000. When the furnace jig 3000 is full (whether it is full can be determined by counting or by additional visual recognition), the pushing assembly 260 can push the furnace jig 3000 to the button unit 400. After the button unit 400 receives the furnace jig 3000, it can press the PCB 2000 onto the furnace jig 3000. Subsequently, the button robot arm 420 can move the buckle on the furnace jig 3000 to fix the PCB 2000 on the furnace jig 3000. Afterwards, the pressing assembly 414 can release the furnace jig 3000 and the PCB 2000, so that the furnace jig 3000 with the PCB 2000 placed on it can enter the next workstation for insertion and other operations. The reflow unit 500 can transport the empty furnace fixtures 3000 after the panels are removed to the lifting unit 200 , and the lifting unit 200 can temporarily store more furnace fixtures 3000 .
