Description

[0001] This application is a divisional application. The original application has the application number "202411041603.6" and the application date "July 31, 2024". The invention title is "High-speed horizontal integrated insertion machine compatible with automatic parts". Technical Field

[0002] This invention relates to the field of insertion machines, and in particular to a high-speed horizontal integrated insertion machine for a conveyor line and corresponding compatible automatic replacement parts. Background Technology

[0003] An insertion machine is a mechanical device that automatically and standardly inserts regularly shaped electronic components into the conductive vias of a printed circuit board. Since the types of electronic components that need to be inserted into the circuit board are diverse, the conveyor line transports multiple different types of electronic components in a set order. However, existing horizontal integrated insertion machines use a transfer conveyor mechanism to receive electronic components from the material station, and then the conveyor line receives electronic components from the transfer conveyor mechanism. This transfer conveyor mechanism receives electronic components from the material station through an open trough. When a specific electronic component needs to be added, other electronic components nearby will fall off as they are conveyed forward. Therefore, it cannot automatically replace defective components, and manual operation is required for defective component replacement, which is time-consuming, poses a risk of injury, and results in high efficiency and low cost.

[0004] Therefore, it is necessary to provide a high-speed horizontal integrated insertion machine that is compatible with automatic parts replacement and a conveyor line to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a high-speed horizontal integrated insertion machine for conveyor lines and corresponding compatible automatic component replenishment, in order to solve the problems of existing insertion machines that cannot automatically replenish components, resulting in high efficiency and low cost.

The conveyor line includes a double hook chain clamp, a conveyor chain, a guide sprocket, a drive guide plate, a fixed frame and a conveying drive mechanism. The fixed frame is set on the crossbeam frame, and the drive guide plate and the conveying drive mechanism are both set on the loading platform.

[0007] Two closed-loop conveyor chains are arranged in parallel. The guide sprocket is mounted on the fixed frame and is driven and engaged on the inner side of the conveyor chain. Multiple double-hook chain clamps are provided on the side of the two conveyor chains that are close to each other. The conveyor drive mechanism is connected to the inner side of the conveyor chain through a corresponding drive sprocket.

[0008] The double-hook chain clamp includes a chain clamp block, chain clamp pressure plates, and a spring. The chain clamp block includes a through-groove mounting groove. Two chain clamp pressure plates are disposed in the mounting groove. The chain clamp pressure plates are elastically rotated in the mounting groove by the spring. The two ends of the chain clamp pressure plates are a driving end and a clamping end, respectively. The driving end and the clamping end extend outside the two ends of the mounting groove, and the clamping end faces outward along the radial direction of the annular conveyor chain. The driving force of the spring causes the clamping ends of the two chain clamp pressure plates to clamp the product. The double-hook chain clamps on the two conveyor chains clamp the two ends of the product respectively.

[0009] The drive guide plate is provided with a first guide groove and an extrusion bar. The conveyor chain is slidably fitted in the first guide groove. The double hook chain clamp is located outside the first guide groove. The extrusion bar contacts the drive end and is used to extrude the drive end so that the clamping ends of the two chain clamp plates move away from each other.

[0010] In this invention, the side of the chain clamping plate slides in contact with the inner wall of the mounting groove, and the rotational trajectories of the two chain clamping plates are parallel.

[0011] The cross-section of the chain clamping plate perpendicular to its rotation axis is a curved arc structure. The side of the two chain clamping plates that is close to each other is an arc-shaped protrusion side. The arc-shaped concave side of the two chain clamping plates is provided with a positioning protrusion for positioning connection with the spring.

[0012] The clamping end of the chain clamping plate is a bent structure, and the clamping ends of the two chain clamping plates are bent toward each other.

[0013] The end of the drive end away from the clamping end is rotatably connected to the chain clamping block via a rotating pin. The other end of the drive end is provided with an arc-shaped pressure surface. A positioning plane is provided on one side of the drive end. The positioning plane is located between the arc-shaped pressure surface and the rotating pin.

[0014] In this invention, the chain clamp block is provided with a V-shaped groove for carrying the product. The V-shaped groove is located between the two chain clamp pressure plates. The clamping ends of the two chain clamps clamp the product to secure the product in the V-shaped groove.

[0015] In this invention, the chain clamp block is further provided with a sliding groove, the groove opening direction is parallel to the extension direction of the clamping end, a bearing is provided in the sliding groove, the axial direction of the bearing is parallel to the rotation axis of the chain clamp pressure plate, and a limit plate is further provided on the drive guide plate, the limit plate is in rolling contact with the bearing on the chain clamp block;

[0016] The chain clamp block has a mounting hole on the side away from the mounting groove for connecting with the conveyor chain. The axial direction of the mounting hole is parallel to the rotation axis of the chain clamp plate, and the mounting hole passes through the slide groove and the external space.

[0017] In this invention, the conveyor line further includes a stabilizing guide plate, a second guide groove is provided on the stabilizing guide plate, the conveyor chain is slidably engaged in the second guide groove, the stabilizing guide plate is located below the driving guide plate, the two sections of the conveyor chain in the first guide groove and the second guide groove are parallel, and the clamping end of the chain clamping plate at the driving guide plate faces the side of the chain clamping block away from the stabilizing guide plate.

[0018] Among them, a driving block is provided above one end of the stabilizing guide plate. The driving block is used to lower and squeeze the driving end of the chain clamping plate on the stabilizing guide plate, so that the clamping ends of the two chain clamping plates are far apart from each other.

[0019] In this invention, the conveyor line further includes a reset drive mechanism and a reset adjustment mechanism. The reset drive mechanism is located at one end of the fixed frame away from the conveyor drive mechanism. The reset drive mechanism is connected to the inner side of the conveyor chain through a corresponding drive sprocket. Multiple guide sprockets are located at different positions on the fixed frame to support the conveyor chain in a ring structure.

[0020] The reset and adjustment mechanism includes a movable sprocket, a connecting rod, and a tension spring. One end of the connecting rod is rotatably connected to the fixed frame, and the other end of the connecting rod is rotatably connected to the movable sprocket. The movable sprocket is driven by the conveyor chain. The two ends of the tension spring are respectively connected to the fixed frame and the connecting rod. The tension of the tension spring causes the movable sprocket to move closer to the conveyor chain.

[0021] Furthermore, a limiting protrusion is provided on the side of the chain clamp block extending from the drive end. The limiting protrusion is located on the side away from the drive end. A limiting wheel is fixedly provided on one side of the drive sprocket connected to the reset drive mechanism. A limiting groove is provided on the circumferential side of the limiting wheel for limiting engagement with the limiting protrusion, so as to stabilize the position of the chain clamp block by limiting the limiting protrusion.

[0022] The present invention also includes a high-speed horizontal integrated insertion machine compatible with automatic component replacement, which uses the above-mentioned conveyor line and further includes: an insertion platform, the feeding platform, an insertion device, a limiting mechanism, and an input line, a working line, and an output line for conveying PCB boards.

[0023] The crossbeam frame is mounted on the insertion platform, and the insertion device is mounted on the crossbeam frame. The insertion device is used to remove the product from the double hook chain clamp.

[0024] The input line and the output line are raised and lowered on the plug-in platform, and the working line is located between the input line and the output line;

[0025] The limiting mechanism includes a baffle plate, a limiting member, and a driving member. The PCB board is provided with a limiting hole corresponding to the limiting member. The driving member is disposed on the input line or the output line. The baffle plate and the limiting member are movably disposed on one side of the working line. The baffle plate includes a blocking position for blocking the PCB board conveying and a clearance position for releasing the PCB board on its moving trajectory. The limiting member includes a limiting position that inserts into the limiting hole and a release position that is a set distance away from the limiting hole on its moving trajectory.

[0026] When the input line and the output line descend and dock with the working line, the driving member descends with the input line or the output line and squeezes the limiting member to the release position. At this time, the baffle plate is located at the baffle position.

[0027] When the input line and the output line descend and dock with the working line, the driving component can drive the baffle plate to be squeezed, so that the baffle plate is located in the material avoidance position;

[0028] When the input line and the output line rise to the set position, the limiting member is located at the limiting position, and the baffle is located at the baffle position.

[0029] In addition, the limiting mechanism also includes a rotating shaft, a connecting rod, a control block, and a torsion spring. The connecting rod is fixedly connected to the working line, the rotating shaft is rotatably connected to the connecting rod, the control block is fixedly connected to one end of the rotating shaft near the driving member, the baffle plate and the limiting member are both fixedly connected to the rotating shaft, the torsion spring is sleeved on the rotating shaft, and both ends of the torsion spring are respectively connected to the control block and the connecting rod. The torsion spring is used to drive the baffle plate and the limiting member to rotate towards the working line.

[0030] In this invention, two limiting members are provided on the rotating shaft. Each limiting member includes a limiting connecting plate, a bent portion, and a limiting post. The bent portion is connected between the limiting connecting plate and the limiting post. The bent portions of the two limiting members are bent in a direction away from each other. A fixing block for connecting the limiting connecting plate is fixedly provided on the rotating shaft. The two limiting members are located between the two connecting rods, and the baffle plate is located outside the connecting rods.

[0031] In this invention, the working line is set on a turntable, the working line includes a fixed conveying track and a movable conveying track, the connecting rod connects the turntable and the fixed conveying track, the two ends of the movable conveying track are connected to the turntable, and the turntable is connected to the plug-in platform through a horizontal moving module and a vertical moving module.

[0032] In this invention, the input line is provided with a stopping mechanism, which includes a stopping plate, a rotating seat, and a movable block. The rotating seat is fixedly disposed at one end of the input line near the working line. One end of the movable block is rotatably connected to the rotating seat. The stopping plate is connected to the movable block and extends to the inside of the input line to block the PCB board conveying. The end of the movable block away from the rotating seat is located above the working line. When the input line descends and docks with the working line, the working line squeezes the movable block to rotate, causing the stopping plate to move away from the input line so that the PCB board can be released.

[0033] The movable block is provided with a second elongated connecting hole, through which the stud passes and connects to the input line. A spring is sleeved on the stud, and the spring is compressed between the screw head of the stud and the movable block. One end of the movable block is provided with a rubber roller for contacting the working line.

[0034] In this invention, the limiting mechanism further includes an elastic plate, an unlocking block, and a locking block. One end of the elastic plate is fixedly connected to the turntable. The unlocking block and the locking block are both disposed at the end of the elastic plate away from the turntable, and the unlocking block is located at the end of the locking block away from the turntable. The top of the locking block includes a locking surface, and the top of the unlocking block includes an unlocking ramp. The unlocking ramp is located on the movement trajectory of the output end of the driving member.

[0035] The limiting member and the control block are respectively located on both sides of the rotation axis in the circumferential direction. When the limiting member is in the restricted position, the locking surface contacts the bottom of the control block at the end away from the limiting member to restrict the limiting member from rotating away from the working line. The unlocking inclined surface is located on the side of the unlocking block closer to the driving member.

[0036] Before the limiting member is raised to the release position, the driving member can first press the unlocking slope, causing the elastic plate to deform away from the control block, thereby causing the locking surface to disengage from the control block.

[0037] Compared with the prior art, the beneficial effects of this invention are as follows: the conveyor line of the insertion machine of this invention can open the chain clamp pressing plate under the drive of the extrusion bar to directly receive electronic components, and then automatically close and clamp the electronic components under the drive of the spring. The insertion machine of this invention does not have a transfer conveyor mechanism, and the conveyor line has only one set of annular conveyor chains. In this way, the electronic components will not be dislodged from the double hook chain clamp due to transfer, and automatic replacement of parts can be achieved, which is highly efficient and low in cost.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] The directional terms mentioned in this invention, such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", "top" and "bottom", are only for reference to the orientation of the accompanying drawings. The directional terms used are for the purpose of explaining and understanding this invention, and are not intended to limit this invention.

[0055] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0056] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, a connection can be a detachable connection or a connection of an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] The existing horizontal integrated insertion machine uses a transfer conveyor mechanism to receive electronic components from the material station, and then the conveyor line receives electronic components from the transfer conveyor mechanism. The transfer conveyor mechanism receives electronic components from the material station through an open trough, which cannot automatically replenish parts. Replenishing defective parts requires manual operation, which is time-consuming and poses a risk of injury to operators. It is inefficient and has a high cost.

[0058] The following is a preferred embodiment of a high-speed horizontal integrated insertion machine compatible with automatic parts replacement, which can solve the above-mentioned technical problems provided by the present invention.

[0059] Please refer to Figures 1-7 In the diagram, units with similar structures are represented by the same labels.

[0060] This invention provides a high-speed horizontal integrated insertion machine compatible with automatic parts replacement, comprising: an insertion platform 11, a feeding platform 12, a conveyor line 13, an insertion device 14, and a shearing device 15. A crossbeam frame 111 is mounted on the insertion platform 11, and the insertion device 14 is mounted on the crossbeam frame 111. The shearing device 15 is located below the insertion device 14. The insertion device 14 and the shearing device 15 are existing structures and will not be described in detail here. They are described in previous applications filed by the applicant, specifically in patent application number 2022108360118, entitled "Horizontal Insertion Machine."

[0061] The conveyor line 13 includes double hook chain clamps 137, conveyor chains 134, guide sprockets 139, drive guide plates 135, fixed frames 131, and conveyor drive mechanisms 133. The fixed frames 131 are mounted on the crossbeam frame 111, and the drive guide plates 135 are mounted on the loading platform 12. Two closed-loop conveyor chains 134 are arranged in parallel. The guide sprockets 139 are mounted on the fixed frames 131 and are driven and engaged on the inner side of the conveyor chains 134. Multiple double hook chain clamps 137 are provided on the side of the two conveyor chains 134 that are close to each other.

[0062] Please refer to Figures 5-7 In this embodiment, the double-hook chain clamp 137 includes a chain clamp block 21, a chain clamp pressure plate 22, and a spring 24.

[0063] The chain clamp block 21 includes a through mounting groove 212, and two chain clamping plates 22 are disposed in the mounting groove 212. The chain clamping plates 22 are elastically rotated in the mounting groove 212 by springs 24. The two ends of the chain clamping plates 22 are a driving end 221 and a clamping end 222, respectively. The driving end 221 and the clamping end 222 extend outward from the two ends of the mounting groove 212, and the clamping end 222 faces outward along the radial direction of the annular conveyor chain 134. The driving force of the spring 24 causes the clamping ends 222 of the two chain clamping plates 22 to clamp the product. The double hook chain clamps 137 on the two conveyor chains 134 clamp the two ends of the product respectively.

[0064] Please refer to Figure 3 and Figure 4The drive guide plate 135 is provided with a first guide groove 1351 and an extrusion bar 1352. The conveyor chain 134 is slidably engaged in the first guide groove 1351. The double hook chain clamp 137 is located outside the first guide groove 1351. The extrusion bar 1352 contacts the drive end 221 and is used to extrude the drive end 221 to make the clamping ends 222 of the two chain clamp pressure plates 22 move away from each other, thereby opening the two clamping ends 222. The two chain clamp pressure plates can unfold a large space, which can facilitate the direct reception of electronic components and has high efficiency. At the same time, the two chain clamp pressure plates press and fix the electronic components from both sides, resulting in high stability.

[0065] The two ends of the extrusion bar 1352 are provided with guide slopes for gradually forming an extrusion with the drive end.

[0066] Multiple material stations 1B are arranged above the drive guide plate 135. Figure 2 Only one material station 1B is shown in the image. Multiple material stations 1B can be used to provide different kinds of electronic components. The clamping ends 222 of the two chain clamping plates 22 are open and facing upwards to receive the products provided by the material station 1B.

[0067] The conveying drive mechanism 133 is mounted on the loading platform 12 and is connected to the inside of the conveying chain 134 via a corresponding drive sprocket.

[0068] In this embodiment, the high-speed horizontal integrated insertion machine compatible with automatic component replenishment is configured with a conveyor line 13 covering the fixing frame 131 of the insertion platform 11 and the drive guide plate 135 of the feeding platform 12. The conveyor line 13 can open the chain clamping plate 22 under the drive of the extrusion bar 1352 to directly receive electronic components, and then automatically close to clamp the electronic components under the drive of the spring 24. When the chain clamping plate 22 is opened, the V-groove 213 opens upward, and the existing electronic components will not fall off. It can replenish a set electronic component to the empty position, realize automatic component replenishment, and achieve high efficiency and low cost.

[0069] Please refer to Figures 5-7 In this embodiment, the side of the chain clamping plate 22 slides in contact with the inner wall of the mounting groove 212, thus ensuring very stable rotation of the chain clamping plate 22. The rotational trajectories of the two chain clamping plates 22 are parallel. That is, the rotational trajectories of the two chain clamping plates 22 are staggered, and they have intersecting areas when clamping the product for better product clamping.

[0070] The cross-section of the chain clamping plate 22 perpendicular to its rotation axis is a curved arc shape, and the side of the two chain clamping plates 22 that is close to each other is an arc-shaped protrusion. This provides more space for the spring 24 and makes the overall structure more compact.

[0071] The two chain clamping plates 22 are provided with positioning protrusions 223 on their arc-shaped concave sides for positioning and connecting with the spring 24, so that the spring and the two chain clamping plates 22 form a stable engagement.

[0072] In this embodiment, the clamping end 222 of the chain clamping plate 22 is a bent structure, and the clamping ends 222 of the two chain clamping plates 22 are bent toward each other, so that the two chain clamping plates 22 can open up a larger space and can also better clamp the product.

[0073] In addition, the end of the drive end 221 away from the clamping end 222 is rotatably connected to the chain clamping block 21 via a rotating pin 23. The other end of the drive end 221 is provided with an arc-shaped pressure surface 2212, which can be squeezed from both sides, causing the chain clamping plate 22 to rotate. A positioning plane 2211 is provided on one side of the drive end 221. The positioning plane 2211 is located between the arc-shaped pressure surface 2212 and the rotating pin 23, so that when the two chain clamping plates 22 are opened to the correct position, the positioning plane 2211 can form a stable surface contact with the corresponding extrusion strip, so that the two chain clamping plates 22 can be stably kept in the open state.

[0074] In this embodiment, the chain clamp block 21 is provided with a V-groove 213 for carrying the product. The V-groove 213 is located between two chain clamp pressure plates 22. The clamping ends 222 of the two chain clamps clamp the product to secure it in the V-groove 213. The V-groove 213 facilitates receiving the product first, and then securing the product in the V-groove 213 through the clamping ends 222 of the two chain clamps.

[0075] In this embodiment, the chain clamp block 21 is also provided with a sliding groove 214. The groove opening direction of the sliding groove 214 is consistent with the extension direction of the clamping end 222. A bearing 25 is provided in the sliding groove 214 through a shaft pin 26. The axial direction of the bearing 25 is parallel to the rotation axis of the chain clamp pressure plate 22. A limiting plate 1353 is also provided on the drive guide plate 135. The limiting plate 1353 makes rolling contact with the bearing on the chain clamp block. In this way, when the drive end 221 slides relative to the corresponding extrusion strip, the limiting plate 1353 extends into the sliding groove 214 and contacts the bearing 25 to achieve smooth movement of the double hook chain clamp 137.

[0076] Among them, the chain clamp block 21 has a mounting hole 215 for connecting with the conveyor chain 134 on the side away from the mounting groove 212. The axial direction of the mounting hole 215 is parallel to the rotation axis of the chain clamp pressure plate 22. The mounting hole 215 passes through the slide groove 214 and the external space.

[0077] Please refer to Figure 4In this embodiment, the conveyor line 13 further includes a stabilizing guide plate 136, on which a second guide groove 1361 is provided. The conveyor chain 134 slides within the second guide groove 1361. The stabilizing guide plate 136 is located below the drive guide plate 135. The two sections of the conveyor chain 134 within the first guide groove 1351 and the second guide groove 1361 are parallel. This allows the conveyor chain 134 to more stably drive the chain clamp block 21 to move and receive electronic components on the loading platform 12. The clamping end 222 of the chain clamp pressure plate 22 at the drive guide plate 135 faces away from the stabilizing guide plate 136, so that the openings of the two clamping ends 222 face upwards to receive electronic components.

[0078] Please refer to Figure 8 In this embodiment, a drive block 1C is provided above one end of the stabilization guide plate 136. The drive block 1C is used to lower and press the drive end 221 of the chain clamping plate 22 on the stabilization guide plate 136, so that the clamping ends 222 of the two chain clamping plates 22 are far apart from each other.

[0079] When a replacement part needs to be added to a specific double-hook chain clamp 137, the drive block 1C rises. This prevents the drive block 1C from squeezing the drive end 221 of the double-hook chain clamp 137, thus preventing the two clamping ends 222 from opening. This also prevents the clamped electronic components from falling off, thereby enabling the replacement part to be added to a specific double-hook chain clamp 137.

[0080] When the conveyor chain 134 is normally conveying electronic components for insertion, the drive block 1C descends, squeezing the double hook chain clamp 137 and opening the two clamping ends 222, causing the clamped waste material to fall down.

[0081] Please refer to Figure 1 and Figure 9 In this embodiment, the conveyor line 13 also includes a reset drive mechanism 132 and a reset adjustment mechanism 138. The reset drive mechanism 132 is located at the end of the fixed frame 131 away from the conveying drive mechanism 133. It is used to drive the conveyor chain 134 to drive the double hook chain clamp 137 to a designated position before inserting the component, so as to accurately pick up and insert the component (by setting a corresponding sensor to determine the position). The reset drive mechanism 132 is connected to the inner side of the conveyor chain 134 through a corresponding drive sprocket 1321. Multiple guide sprockets 139 are set at different positions of the fixed frame 131 to support the conveyor chain 134 as a ring structure.

[0082] Please refer to Figure 10The reset and adjustment mechanism 138 includes a movable sprocket 1381, a connecting rod 1382, and a tension spring 1383. One end of the connecting rod 1382 is rotatably connected to the fixed frame 131, and the other end of the connecting rod 1382 is rotatably connected to the movable sprocket 1381. The movable sprocket 1381 is connected to the conveyor chain 134. The two ends of the tension spring 1383 are respectively connected to the fixed frame 131 and the connecting rod 1382. The tension of the tension spring 1383 causes the movable sprocket 1381 to move closer to the conveyor chain 134.

[0083] When the reset drive mechanism 132 drives the conveyor chain 134 to move and reset, the movement of the movable sprocket 1381 can retract or release the conveyor chain 134. This will not affect the conveyor chain 134 at the drive guide plate 135, and electronic components can still be stably fed into the double hook chain clamp 137 at the drive guide plate 135. That is, one end of the conveyor chain 134 can be driven, adjusted, and reset at one end while the double hook chain clamp 137 at the other end of the conveyor chain 134 is fed at the same time, resulting in stable operation and high efficiency.

[0084] Please refer to Figure 5 and Figure 9 In this embodiment, a limiting protrusion 211 is provided on one side of the drive end 221 of the chain clamp block 21. The limiting protrusion 211 is located on the side away from the drive end 221. A limiting wheel 1322 is fixedly provided on one side of the drive sprocket 1321 connected to the reset drive mechanism 132. A limiting groove 1323 is provided on the circumferential side of the limiting wheel 1322 for limiting and cooperating with the limiting protrusion 211, so as to stabilize the position of the chain clamp block 21 by limiting the limiting protrusion 211, so as to facilitate the insertion device 14 to accurately remove the product from the double hook chain clamp 137.

[0085] Please refer to Figure 1 In this invention, the high-speed horizontal integrated insertion machine compatible with automatic component replacement also includes a limiting mechanism 19 and an input line 16, a working line 17, and an output line 18 for conveying PCB boards. The input line 16 and the output line 18 are lifted and lowered on the insertion platform 11, and the working line 17 is located between the input line 16 and the output line 18.

[0086] Please refer to Figure 11 The limiting mechanism 19 includes a baffle plate 191, a limiting member 192, and a driving member 197. In this embodiment, the driving member 197 is a cylinder. The PCB board is provided with a limiting hole corresponding to the limiting member 192. The driving member 197 is disposed on the input line 16 or the output line 18 (in this embodiment, the driving member 197 is disposed on the input line 16). The baffle plate 191 and the limiting member 192 are movably disposed on one side of the working line 17.

[0087] The baffle plate 191 includes a baffle position for blocking the PCB board conveying and a clearance position for releasing the PCB board on its moving trajectory. The limiting member 192 includes a limiting position that is inserted into the limiting hole and a release position that is a set distance away from the limiting hole on its moving trajectory.

[0088] When the input line 16 and the output line 18 descend to dock with the working line 17, the drive unit 197 descends with the input line 16 or the output line 18 and presses the limiting member 192 to the release position. At this time, the baffle plate 191 is in the baffle position. At this time, the PCB board can be conveyed from the input line 16 to the working line 17 and blocked by the baffle plate 191.

[0089] When the input line 16 and the output line 18 descend and connect with the working line 17, the drive unit 197 can be activated to drive the extrusion baffle 191 to tilt up, so that the baffle 191 is in the material avoidance position. At this time, the PCB board that has completed the insertion operation can be transported from the working line 17 to the output line 18 for unloading operation.

[0090] When the input line 16 and the output line 18 rise to the set position, the limiting member 192 is in the limiting position and the baffle plate 191 is in the baffle position. At this time, the PCB board that is conveyed to the working line 17 can be blocked, and the PCB board can be fixed by the limiting member 192 and the limiting hole on the PCB board for insertion operation.

[0091] Please refer to Figure 11 Specifically, the limiting mechanism 19 also includes a rotating shaft 193, a connecting rod 194, a control block 195, and a torsion spring 196. The connecting rod 194 is fixedly connected to the working line 17, the rotating shaft 193 is rotatably connected to the connecting rod 194, the control block 195 is fixedly connected to one end of the rotating shaft 193 near the driving member 197, the baffle plate 191 and the limiting member 192 are both fixedly connected to the rotating shaft 193, and the torsion spring 196 is sleeved on the rotating shaft 193, with both ends of the torsion spring 196 connected to the control block 195 and the connecting rod 194 respectively. The torsion spring 196 is used to drive the baffle plate 191 and the limiting member 192 to rotate towards the working line 17, that is, the torsion spring 196 is used to drive the baffle plate 191 to the baffle position and drive the limiting member 192 to the limiting position.

[0092] Please refer to Figure 12In this embodiment, two limiting members 192 are provided on the rotating shaft 193. The limiting member 192 includes a limiting connecting plate 1921, a bending part 1922, and a limiting post 1923. The bending part 1922 is connected between the limiting connecting plate 1921 and the limiting post 1923. The bending parts 1922 of the two limiting members 192 bend in a direction away from each other. A fixing block 198 for connecting the limiting connecting plate 1921 is fixedly provided on the rotating shaft 193. The two limiting members 192 are located between the two connecting rods 194. The baffle plate 191 is located outside the connecting rod 194. The structure is more compact, and the limiting holes on the PCB board can be set closer to their edges.

[0093] The limiting connection plate 1921 is provided with an elongated hole for adjustable connection with the fixing block 198, so as to adjust the position of the limiting member 192 relative to the PCB board.

[0094] In this embodiment, the working line 17 is set on the turntable 1A. The working line 17 includes a fixed conveying track 171 and a movable conveying track 172. The connecting rod 194 connects the turntable 1A and the fixed conveying track 171. The two ends of the movable conveying track 172 are connected to the turntable 1A. By adjusting the connection position between the movable conveying track 172 and the turntable 1A, the distance between the fixed conveying track 171 and the movable conveying track 172 can be adjusted so as to convey PCB boards of different sizes and specifications.

[0095] Turntable 1A is connected to plug-in platform 11 through horizontal and vertical movement modules, which enables it to rotate and translate the PCB board on the work line 17 to perform plug-in operations at different positions and orientations on the PCB board.

[0096] Please refer to Figure 14 In this embodiment, the input line 16 is provided with a stop mechanism, which includes a stop plate 1D1, a rotating seat 1D2, and a movable block 1D3. The rotating seat 1D2 is fixedly disposed at one end of the input line 16 near the working line 17. One end of the movable block 1D3 is rotatably connected to the rotating seat 1D2. The stop plate 1D1 is connected to the movable block 1D3 and extends to the inner side of the input line 16 to block the PCB board from being transported.

[0097] The end of the movable block 1D3 furthest from the rotating seat 1D2 is located above the working line 17. When the input line 16 descends and docks with the working line 17, the working line 17 squeezes the movable block 1D3 to rotate, causing the stop plate 1D1 to move away from the input line 16. When the input line 16 descends and docks with the working line 17, the PCB board can be automatically released, making the operation highly efficient and cost-effective.

[0098] The movable block 1D3 is provided with a second elongated connecting hole. The stud 1D4 passes through the second elongated connecting hole and connects to the input line 16. A spring is sleeved on the stud 1D4. The spring is compressed between the screw head of the stud 1D4 and the movable block 1D3. The driving force of the spring makes the stop plate 1D1 extend to the inside of the input line 16 to block the PCB board.

[0099] One end of the movable block 1D3 is provided with a rubber roller 1D5 for contacting the working line 17. The working line 17 causes the movable block 1D3 to rotate by squeezing the rubber roller 1D5, resulting in less friction and quieter operation.

[0100] Please refer to Figure 13 In this embodiment, since the PCB board may still wobble up and down during the insertion process when the limiting member 192 is driven by the torsion spring 196 to cooperate with the limiting hole of the PCB board to form a clamping effect, the limiting mechanism 19 in this embodiment also includes an elastic plate 199, an unlocking block 19A, and a locking block 19B.

[0101] One end of the elastic plate 199 is fixedly connected to the turntable 1A. The unlocking block 19A and the locking block 19B are both located at the end of the elastic plate 199 away from the turntable 1A. The unlocking block 19A is located at the end of the locking block 19B away from the turntable 1A. The top of the locking block 19B includes a locking surface, and the top of the unlocking block 19A includes an unlocking ramp. The unlocking ramp is located on the movement trajectory of the output end of the drive unit 197.

[0102] The limiting member 192 and the control block 195 are located on both sides of the circumference of the rotating shaft 193. When the limiting member 192 is in the limiting position, the locking surface contacts the bottom of the control block 195 at the end away from the limiting member 192, so as to limit the limiting member 192 from rotating in the direction away from the working line 17, so as to stably press and limit the PCB board, making it less prone to shaking and the insertion effect is good.

[0103] The unlocking ramp is located on the side of the unlocking block 19A close to the drive member 197. When the output end of the drive member 197 presses the control block 195 to make the limit member 192 tilt to the release position, the drive member 197 will first press the unlocking ramp, causing the elastic plate 199 to deform in a direction away from the control block 195, thereby causing the locking surface to disengage from the control block 195 and releasing the restriction of the locking block 19B on the control block 195.

[0104] The working process of the high-speed horizontal integrated insertion machine compatible with automatic parts of the present invention is as follows: when the input line 16 and the output line 18 descend from the high position and dock with the working line 17, the driving component 197 descends with the input line 16 and squeezes the limiting component 192 to the release position.

[0105] Then, by starting the drive unit 197, the extrusion baffle 191 can be driven to tilt up, so that the baffle 191 is in the material avoidance position. At this time, the PCB board that has completed the insertion operation can be transported from the working line 17 to the output line 18 for unloading operation.

[0106] Then, the drive unit 197 stops the extension drive and returns to the initial position. At this time, the limit unit 192 is in the released position, the baffle plate 191 is in the baffle position, and the new PCB board is conveyed from the input line 16 to the working line 17 and blocked by the baffle plate 191.

[0107] Finally, the input line 16 and the output line 18 rise, and the torsion spring 196 drives the limiting member 192 to the limiting position and drives the baffle plate 191 to the baffle position. At this time, the PCB board conveyed to the working line 17 can be blocked, and the PCB board can be fixed by the limiting member 192 and the limiting hole on the PCB board. The working line 17 can be controlled to move or rotate to perform various plug-in operations.

[0108] On the other hand, the conveyor drive mechanism 133 can drive the conveyor chain 134 to operate. The conveyor chain 134 drives the double hook chain clamp 137 to circulate and convey electronic components. During normal operation, when the double hook chain clamp 137 reaches the extrusion bar 1352, the clamping ends 222 of the two chain clamp pressure plates 22 will open upwards to receive the products provided by the material station 1B. At the same time, the drive block 1C will descend, which can squeeze the double hook chain clamp 137, open the two clamping ends 222, and cause the clamped waste to fall down.

[0109] When replacement parts are needed, the drive block 1C rises, so that the drive block 1C will not squeeze the drive end 221 of the double hook chain clamp 137, and therefore will not open the two clamping ends 222. In this way, the clamped electronic components will not fall off. The clamping ends 222 of the two chain clamp pressure plates 22 will only open when the double hook chain clamp 137 reaches the extrusion bar 1352. A set material station 1B will then replace the part with a set double hook chain clamp 137. After the replacement is completed, the conveyor chain 134 will be driven to run and transport the replaced electronic components to the insertion point.

[0110] This completes the automated insertion process of the high-speed horizontal integrated insertion machine compatible with automatic parts in this preferred embodiment.

[0111] The conveyor line of the high-speed horizontal integrated insertion machine compatible with automatic component replacement in this preferred embodiment can open the chain clamp pressure plate under the drive of the extrusion bar to directly receive electronic components, and then automatically close and clamp the electronic components under the drive of the spring. The insertion machine of the present invention does not have a transfer conveyor mechanism. The conveyor line has only one set of annular conveyor chains. In this way, the electronic components will not be dislodged from the double hook chain clamp due to transfer, and automatic component replacement can be achieved with high efficiency and low cost.

[0112] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
