Description

Technical Field

[0001] This invention belongs to the field of circuit board processing technology, and in particular relates to a feeding and conveying device for assembling electronic components. Background Technology

[0002] After electronic components are installed on one side of the circuit board through a preset assembly process, in order to ensure that the electronic components can be stably and reliably fixed on the circuit board, it is necessary to perform a resoldering operation on the other side of the circuit board after the initial installation of the electronic components. This will form a solid mechanical connection and a reliable electrical connection between the electronic components and the circuit board, effectively preventing the circuit board from malfunctioning due to connection failure during subsequent use.

[0003] For example, Chinese Patent CN119031598B discloses a circuit board flipping device. The first motor drives the bogie to rotate, which can transfer the position of the circuit board. During the transfer, the teeth drive the transmission gear to rotate, which can make the flipping frame rotate the circuit board by 180°, thus realizing the synchronous operation of moving and flipping the circuit board.

[0004] However, the device uses a conveyor belt to transport the circuit boards laterally when flipping and transferring them. Considering that workshop layouts are usually quite compact, this method not only requires a lot of floor space to place the flipped circuit boards, but also further increases the floor space requirement when dealing with continuous circuit board processing scenarios. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding and conveying device for assembling electronic components. By setting two sets of vertically distributed conveying support components, the corresponding transmission plates in the two sets of components jointly form a stable support for the circuit board. With its vertical layout structure, the problem of large footprint caused by the horizontal conveying method in existing circuit board flipping and conveying devices is solved.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a feeding and conveying device for assembling electronic components, comprising a movable support body, a transmission drive assembly mounted on the movable support body, and two sets of conveying support assemblies disposed within the movable support body. The transmission drive assembly is connected to a clamping assembly, and the clamping assembly has a clamping drive assembly at its end. The transmission drive assembly drives the clamping assembly to rotate, thereby achieving the flipping and movement of the circuit board. Each set of conveying support assemblies includes several transmission plates, with the transmission plates of the two sets of conveying support assemblies corresponding one-to-one. The transmission drive assembly synchronously drives the two sets of conveying support assemblies and the clamping assembly to move, and uses the clamping assembly to flip the circuit board, placing the circuit board between the two sets of conveying support assemblies. The corresponding transmission plates of the two sets of conveying support assemblies support the circuit board and drive it to be conveyed vertically.

[0008] As a preferred embodiment of the present invention, the transmission support assembly includes a transmission rod and a rotating rod that rotate on the inner wall of the movable support body. The transmission rod and the rotating rod are arranged at vertical intervals. Both the transmission rod and the rotating rod are fixedly connected to a sprocket. A chain is meshed with the outer edge of the sprocket. Several transmission plates are evenly distributed on the surface of the chain.

[0009] As a preferred embodiment of the present invention, the transmission drive assembly includes a motor, two drive gears and two transmission gears. The two transmission gears are respectively fixedly connected to two transmission rods. The two drive gears are rotatably connected to the inner wall of the movable support body. The two drive gears mesh with each other and are respectively meshed with the two transmission gears. The motor is fixedly connected to the movable support body, and its output end is connected to one of the drive gears.

[0010] As a preferred embodiment of the present invention, the clamping assembly includes a connecting block connected to a transmission rod. The connecting block is fixedly connected to a support plate. The support plate is rotatably connected to two half-gears, which mesh with each other. Each half-gear is fixedly connected to a connecting rod. The connecting rod is hinged to a clamping plate. The surface of the support plate is rotatably connected to two strip plates, one end of which is hinged to the two clamping plates respectively.

[0011] As a preferred embodiment of the present invention, rubber pads are fixedly connected to the clamping surfaces of both clamping plates, and the rubber pads are used to prevent damage to the circuit board due to excessive clamping.

[0012] As a preferred embodiment of the present invention, the support plate is slidably connected to a connecting plate, the connecting plate is fixedly connected to a lead screw, a spring is provided between the connecting plate and the support plate, and a threaded hole that mates with the lead screw is opened at the rotation center of one of the half gears. The lead screw is driven to move axially by the drive assembly, thereby driving the half gear to rotate.

[0013] In a preferred embodiment of the present invention, the connecting plate is fixedly connected to a guide post, and the support plate is slidably connected to the connecting plate via the guide post.

[0014] As a preferred embodiment of the present invention, a fixed shaft is fitted inside the transmission rod, and an axially oriented straight groove is formed on the side wall of the transmission rod. The fixed shaft is fixedly connected to the movable support body, and a cam groove is formed on the circumferential surface of the fixed shaft. The connecting block has a connecting hole that mates with the transmission rod, and a protrusion is fixedly connected to the inner wall of the connecting hole. The protrusion passes through the straight groove and mates with the cam groove. The transmission rod drives the connecting block to rotate, and the mate between the protrusion and the cam groove enables the connecting block to move axially along the transmission rod.

[0015] As a preferred embodiment of the present invention, the driving component includes a telescopic device fixedly connected to the movable support body, and an arc-shaped plate is fixedly connected to the telescopic end of the telescopic device. The arc-shaped plate corresponds to the position of the connecting plate, and the connecting plate is pushed by the arc-shaped plate.

[0016] As a preferred embodiment of the present invention, the arc-shaped plate is half-arc-shaped. When the arc-shaped plate abuts against the clamping assembly, it is used to clamp the circuit board. When the clamping assembly disengages from the arc-shaped plate, it releases the clamping of the circuit board.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention uses two sets of transmission rods and rotating rods spaced vertically and vertically, combined with the meshing transmission of sprockets and chains, to make the transmission plates evenly distributed on the chain surface form a vertical circulating conveyor track, replacing the traditional horizontal conveyor belt. It changes the circuit board conveying path from a long horizontal extension to a vertical downward movement within the equipment body, solving the problem that horizontal conveying requires a large amount of workshop space. It is especially suitable for compact workshop layouts and greatly improves space utilization.

[0019] 2. This invention uses the axial movement of the arc-shaped plate to abut against the connecting plate, causing the two half-gears to mesh with each other and drive the connecting rod to move synchronously in opposite directions. Combined with the rotational constraint of the clamping plate by the strip plate, the two clamping plates always remain parallel and move closer or further apart to clamp the circuit board. The arc-shaped plate is semi-circular, and its curved surface structure can continuously abut against the connecting plate during the rotation of the clamping assembly, keeping the clamping assembly in a clamped state until it is naturally released after being flipped 180°. It can achieve gripping, flipping, and releasing without the need for an additional locking mechanism.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] 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.

[0034] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0035] Please see Figure 1 As shown, the present invention is a feeding and conveying device for assembling electronic components, including a movable support body 1, a transmission drive assembly 2 installed on the movable support body 1, two sets of conveying support assemblies 3 arranged inside the movable support body 1, a clamping assembly 5 connected to the transmission drive assembly 2, a clamping drive assembly 4 provided at the end of the clamping assembly 5, and the clamping assembly 5 is driven to rotate by the transmission drive assembly 2 to realize the flipping and moving of the circuit board.

[0036] Each set of transmission support components 3 includes several transmission plates 33, and the transmission plates 33 of the two sets of transmission support components 3 correspond one-to-one.

[0037] The transmission drive assembly 2 synchronously drives the two sets of transmission support assemblies 3 and clamping assembly 5 to move, and the clamping assembly 5 drives the circuit board to rotate 180° so that the circuit board is located between the two sets of transmission support assemblies 3. The corresponding transmission plates 33 of the two sets of transmission support assemblies 3 support the circuit board and drive the circuit to be transported in the vertical direction.

[0038] The clamping drive assembly 4 drives the clamping assembly 5 to clamp the circuit board to be processed. Simultaneously, the transmission drive assembly 2 starts, driving the conveying support assembly 3 and the clamping assembly 5 to rotate 180° (half a revolution). During this process, the circuit board is carried by the clamping assembly 5 and stably completes the flipping. After half a revolution, the circuit board is transferred to the corresponding two sets of transmission plates 33 at the first workstation S1, where they jointly achieve reliable reception and synchronous support. After receiving the circuit board, the conveying support assembly 3 continues to rotate half a revolution under the drive of the transmission drive assembly 2. This action causes the transmission plate 33 carrying the circuit board to move downwards, achieving orderly storage of the circuit board within the equipment body. The non-horizontal conveying method occupies less workshop space, but greatly reduces the floor space required. At the same time, the clamping component 5 continues to rotate for the remaining half revolution with the transmission drive component 2 and automatically resets to the initial clamping position. Meanwhile, the conveying support component 3 has transported the next set of empty transmission plates 33 to the first station S1 to prepare for receiving the next circuit board. The transmission drive component 2 continues to run, and the transmission plate 33 carrying the circuit board moves to the second station S2. When the transmission plate 33 reaches the second station S2, the support for the circuit board is gradually released, and the entire conveying support component 3 supports the conveyed circuit board vertically, which takes up less floor space than the circuit board after being flipped by horizontal conveying.

[0039] like Figure 2 As shown, the conveying support assembly 3 includes a transmission rod 34 and a rotating rod 36 that rotate on the inner wall of the movable support body 1. The transmission rod 34 and the rotating rod 36 are arranged at vertical intervals. Both the transmission rod 34 and the rotating rod 36 are fixedly connected to a sprocket 31. A chain 32 is meshed with the outer edge of the sprocket 31. Several transmission plates 33 are evenly distributed on the surface of the chain 32. The circuit board is conveyed from the upstream equipment to the clamping station. The clamping drive assembly 4 is activated, driving the clamping assembly 5 to close and grasp the circuit board. At the same time, the drive assembly 2 drives the transmission rod 34 to rotate. The transmission rod 34 drives the chains 32 on both sides to move one station distance through the sprockets 31 at both ends. The movement of the chains 32 causes a pair of empty transmission plates 33 to move to the first station S1 and stop. After the clamping assembly 5 rotates 180°, it immediately releases and places the circuit board smoothly on the pair of transmission plates 33 that are already in place. The transmission drive assembly 2 continues to run, driving the transmission rod 34 to rotate again, driving the chains 32 to move one station. At this time, the transmission plate 33 carrying the circuit board moves downward to transport the circuit board.

[0040] Each set of transmission support components 3 consists of a transmission rod 34, a rotating rod 36, a sprocket 31 mounted on the rod, and a chain 32 sleeved on the sprocket. The two transmission rods 34 are driven synchronously by the transmission drive component 2 to ensure that the movement of the chains 32 on both sides is completely consistent. The two ends of the transmission plate 33 are fixed on the chains 32 on both sides respectively. Due to the synchronous movement of the chains, these transmission plates 33 always remain horizontal and aligned during the cycle.

[0041] like Figure 2 , Figure 3 As shown, the transmission drive assembly 2 includes a motor 21, two drive gears 22 and two transmission gears 23. The two transmission gears 23 are fixedly connected to the two transmission rods 34 respectively. The two drive gears 22 are rotatably connected to the inner wall of the movable support body 1. The two drive gears 22 mesh with each other and mesh with the two transmission gears 23 respectively.

[0042] The motor 21 is fixedly connected to the movable support body 1, and its output end is connected to one of the drive gears 22. When the motor 21 starts, its output end drives the drive gear 22 connected to it to rotate. Since the two drive gears 22 mesh with each other, they can rotate in opposite directions synchronously. Then, through meshing with the two transmission gears 23, they drive the two transmission rods 34 to rotate synchronously. The transmission rods 34 drive the chain 32 of the transmission support assembly 3 to move, so that the empty transmission plate 33 is accurately delivered to the first station S1 to receive the circuit board, and at the same time, it drives the clamping assembly 5 to flip.

[0043] like Figure 2 As shown, a rubber pad is fixedly connected to the bearing surface of the transmission plate 33, and the rubber pad is used to buffer the circuit board.

[0044] like Figure 4 , Figure 5 As shown, the clamping assembly 5 includes a connecting block 51, which is connected to the transmission rod 34. The connecting block 51 is fixedly connected to a support plate 52, and the support plate 52 is rotatably connected to two half gears 53, which mesh with each other.

[0045] Both halves of the gear 53 are fixedly connected to a connecting rod 530, and the connecting rod 530 is hinged to a clamping plate 54. Two strip plates 55 are rotatably connected to the surface of the support plate 52, and one end of each strip plate 55 is hinged to the two clamping plates 54 respectively.

[0046] Initial state: The two half gears 53 are not fully engaged, and the two clamping plates 54 are far apart from each other;

[0047] Drive meshing: When one of the half gears 53 rotates under the drive of an external force, the meshing relationship between the two half gears 53 is used to drive the other half gear 53 to rotate synchronously in the opposite direction;

[0048] Clamping action: The relative rotation of the two half gears 53 drives the connecting rod 530 on them to move. The connecting rod 530 pulls one end of the clamping plate 54 downward, while the other end of the clamping plate 54 is provided with rotational constraint by the strip plate 55. Under this linkage mechanism, the two clamping plates 54 approach each other in a way that always keeps them parallel, thereby stably clamping the circuit board located between them.

[0049] like Figure 4 , Figure 5 As shown, rubber pads are fixedly connected to the clamping surfaces of both clamping plates 54. The rubber pads are used to prevent the circuit board from being damaged due to excessive clamping. When the two sets of clamping plates 54 are close to each other and in contact with the upper and lower ends of the circuit board, the elastic deformation characteristics of the rubber material are used to offset the pressure generated by excessive clamping and prevent the circuit board from being damaged due to excessive clamping force.

[0050] like Figure 4 , Figure 5 As shown, a connecting plate 560 is slidably connected to the support plate 52, a lead screw 56 is fixedly connected to the connecting plate 560, and a spring 561 is provided between the connecting plate 560 and the support plate 52.

[0051] One of the half gears 53 has a threaded hole at its rotation center that mates with the lead screw 56. The clamping drive assembly 4 pushes the lead screw 56 to move axially, thereby driving the half gear 53 to rotate. When the clamping drive assembly 4 is activated, it pushes the lead screw 56 to move axially, causing the lead screw 56 to generate axial displacement. The axial displacement of the lead screw 56 is converted into the rotational motion of the half gear 53, causing the two half gears 53 to mesh in opposite directions. This causes the two clamping plates 54 to move closer to each other and clamp the circuit board. During this process, the spring 561 is compressed, and the connecting plate 560 slides on the inner wall of the support plate 52.

[0052] like Figure 4 , Figure 5 As shown, the connecting plate 560 is fixedly connected to the guide post, and the support plate 52 is slidably connected to the connecting plate 560 through the guide post; the screw 56 is driven to move axially by the clamping drive assembly 4, so that the connecting plate 560 is slidably connected to the support plate 52 by means of the guide post.

[0053] like Figure 8 As shown, considering that after the circuit board is released from its clamping state, under the operation of the transmission drive assembly 2, the two corresponding transmission plates 33 will move downward synchronously. At this time, the clamping plate 54 located below the circuit board will block the downward movement of the circuit board. Therefore, a fixed shaft 35 is sleeved inside the transmission rod 34, and an axially arranged straight groove 340 is opened on the side wall of the transmission rod 34. The fixed shaft 35 is fixedly connected to the movable support body 1, and a cam groove 350 is opened on the circumferential surface of the fixed shaft 35.

[0054] The connecting block 51 has a connecting hole that mates with the transmission rod 34. A protrusion 510 is fixedly connected to the inner wall of the connecting hole. The protrusion 510 passes through the straight groove 340 and mates with the cam groove 350. The connecting block 51 is rotated by the transmission rod 34. The connecting block 51 moves axially along the transmission rod 34 by the engagement of the protrusion 510 with the cam groove 350.

[0055] Connecting block 51 engages with transmission rod 34 through connecting hole. Protrusion 510 on inner wall of connecting hole penetrates straight groove 340 on side wall of transmission rod 34 and forms a fitting with cam groove 350. At this time, protrusion 510 is located in initial circumferential groove section of cam groove 350. Connecting block 51 and transmission rod 34 remain axially relatively stationary. Clamping assembly 5 is in clamping position. Two clamping plates 54 open. Transmission drive assembly 2 starts, driving transmission rod 34 to rotate around fixed shaft 35. Due to the protrusion 510 being in contact with the transmission rod 34, the transmission rod 34 rotates around fixed shaft 35. When the transmission rod 34 is engaged with the straight slot 340 and the cam groove 350, the rotation of the transmission rod 340 drives the protrusion 510 to slide along the circumferential groove of the cam groove 350, thereby driving the connecting block 51 and the connected clamping assembly 5 to rotate synchronously. During this stage, the circumferential structure of the cam groove 350 restricts the axial movement of the connecting block 51, achieving only pure rotational motion. In conjunction with the action of the clamping drive assembly 4, the clamping assembly 5 completes the gripping of the circuit board. The transmission rod 34 continues to rotate, driving the clamping assembly 5 to carry the circuit board. During the board flipping process, the protrusion 510 slides along the circumferential groove of the cam groove 350, while the connecting block 51 maintains its axial position, ensuring that the clamping assembly 5 stably clamps the circuit board to complete the 180° flip. At the same time, the rotation of the transmission rod 34 synchronously drives the chain 32 of the transmission support assembly 3 to move, accurately delivering the empty transmission plate 33 bracket to the first station S1 to prepare for receiving the circuit board. After the clamping assembly 5 flips 180°, the protrusion 510 moves to the junction of the circumferential groove and the axial groove of the cam groove 350 as the transmission rod 34 continues to rotate. The transmission rod 34 continues to rotate, and the axial groove of the cam groove 350 generates an axial guiding force on the protrusion 510. At the same time, the straight groove 340 provides a channel for the axial movement of the protrusion 510, forcing the protrusion 510 to drive the connecting block 51 and the clamping assembly 5 to move axially away from the circuit board along the transmission rod 34. This action allows the clamping assembly 5 to quickly exit from under the circuit board, making way for the vertical transport of the circuit board and avoiding interference.

[0056] like Figure 4 , Figure 5As shown, the clamping drive assembly 4 includes a telescopic device 41 fixedly connected to the movable support body 1. An arc-shaped plate 43 is fixedly connected to the telescopic end of the telescopic device 41. The arc-shaped plate 43 corresponds to the position of the connecting plate 560. The connecting plate 560 is pushed by the arc-shaped plate 43. At this time, the telescopic end of the telescopic device 41 is in a retracted state, which drives the arc-shaped plate 43 to maintain a certain gap with the connecting plate 560, without abutting. The two clamping plates 54 of the clamping assembly 5 are in an open state, and the spring 561 is in a naturally extended state. The telescopic device 41 is activated, and its telescopic end extends outward along the axial direction. The telescopic device 41 can be a linear drive element such as a cylinder or an electric push rod. Here, relying on its stable thrust output characteristics, the power is directly transmitted to the fixedly connected arc-shaped plate 43. The extension device 41 drives the arc plate 43 to move axially toward the connecting plate 560. As the extension device 41 continues to extend, the curved end of the arc plate 43 contacts and abuts against the surface of the connecting plate 560. After abutting, the extension device 41 continues to output thrust, which is transmitted to the connecting plate 560 through the arc plate 43. This forces the connecting plate 560 to slide along the guide post and the support plate 52. When the connecting plate 560 slides under the push of the arc plate 43, it simultaneously drives the fixedly connected lead screw 56 to make axial displacement. The lead screw 56 engages with the threaded hole at the rotation center of one of the half gears 53, converting the linear motion into the rotational motion of the half gear 53. Then, through the meshing relationship of the two half gears 53, it drives the other half gear 53 to rotate synchronously in the opposite direction.

[0057] like Figure 4 , Figure 5 As shown, the arc plate 43 is half an arc. When the arc plate 43 abuts against the clamping component 5, it is used to clamp the circuit board. When the clamping component 5 disengages from the arc plate 43, it releases the clamping of the circuit board.

[0058] When the clamping assembly 5 starts to rotate and flip under the drive of the transmission drive assembly 2, the telescopic device 41 keeps the telescopic end extended. Since the arc plate 43 is half-arc, it is perfectly matched with the rotation trajectory of the connecting plate 560. It can continuously abut against the connecting plate 560 throughout the entire process of the clamping assembly 5 rotating 180°, providing stable axial pressure to the connecting plate 560, ensuring that the meshing state of the half gear 53 remains unchanged, and the clamping plate 54 always clamps the circuit board. When the clamping assembly 5 completes the 180° flip, it will naturally disengage from the abutment range of the half-arc plate 43.
