Description

Technical Field

[0001] This utility model belongs to the technical field of solder paste printing machines, and in particular relates to an automatic conveying mechanism and printing equipment. Background Technology

[0002] Circuit boards are core components in electronic products. As electronic products become smaller and more precise, circuit board production is usually accomplished using surface mount technology (SMT). The first step in circuit board production is printing solder paste onto the circuit board, which is usually done automatically using a solder paste printer.

[0003] The circuit board conveying mechanism is a component within a solder paste printer used to transport circuit boards. It typically includes two spaced-apart conveyor rails that support and transport the circuit boards from both sides. To improve the applicability and versatility of the solder paste printer, the circuit board conveying mechanism also includes an adjustment assembly installed between the two conveyor rails. This assembly allows adjustment of the distance between the two rails, enabling them to transport circuit boards of different widths.

[0004] In existing technology, the adjustment mechanism typically includes a handwheel, a lead screw, and a nut mounted on the conveyor rail. The nut is threaded onto the lead screw, and the handwheel is mounted on the lead screw. The user rotates the lead screw by turning the handwheel, and the lead screw, through the nut, moves one of the conveyor rails, thereby adjusting the distance between the two conveyor rails. This manual adjustment mechanism suffers from technical problems such as inconvenience in operation and low automation. With the continuous advancement of automation technology, some solder paste printing machines are equipped with automatic adjustment components. These automatic adjustment components can adjust the distance between the two conveyor rails via motors, etc. However, when there are protruding parts between the two conveyor rails, interference can occur when the automatic adjustment component moves the conveyor rails. Manual inspection is required to ensure there are no protruding parts between the two conveyor rails before the automatic adjustment component can move the conveyor rails. Summary of the Invention

[0005] This utility model provides an automatic conveying mechanism and printing equipment to solve the technical problems in the prior art, such as interference between the automatic adjusting component and the protruding component when the conveying guide rail moves.

[0006] One embodiment of this utility model provides an automatic conveying mechanism, including a sensing component, an automatic adjustment component, and two conveying components spaced apart. Each conveying component includes a support guide rail and a conveying assembly mounted on the support guide rail. The automatic adjustment component is connected to the support guide rail and is used to adjust the distance between the two conveying components.

[0007] The sensing component includes a sensor transmitter and a sensor receiver spaced apart on the support rails. The sensing component is located between the two conveying components and is used to detect whether there is an obstruction between the two support rails.

[0008] Optionally, the automatic adjustment component includes an adjustment motor, a lead screw, and a nut sleeve mounted on the support guide rail. The nut sleeve is threaded onto the lead screw, and the adjustment motor is connected to the lead screw.

[0009] Optionally, the conveying assembly includes a conveying motor, a conveyor belt, and at least two pulleys rotatably mounted at intervals on the support rail, the conveyor belt being wound around all the pulleys, and the conveying motor being mounted on the support rail and connected to one of the pulleys.

[0010] Optionally, the conveying component further includes a support block mounted on the support rail, the support block being used to support the conveyor belt.

[0011] Optionally, the automatic conveying mechanism further includes a lifting component installed between the two conveying components. The lifting component includes a lifting drive and a top plate installed at the output end of the lifting drive. The lifting drive is used to drive the top plate to rise and fall, so that the top plate is lifted away from the conveying component, or so that the conveying component on the top plate is transferred to the conveying component.

[0012] Optionally, the automatic conveying mechanism further includes two clamping components, which are installed one-to-one on the support guide rail;

[0013] The clamping component includes a clamping drive and a clamping plate installed at the output end of the clamping drive; the clamping drive is installed on the support guide rail and connected to the clamping plate, and is used to drive the clamping plate to clamp the part to be transported on the top plate from opposite ends.

[0014] Optionally, the top plate is provided with a insertion slot, and the automatic conveying mechanism further includes a support member that can be detachably installed in the insertion slot, and the top plate supports the item to be conveyed through the support member.

[0015] Another embodiment of this utility model provides a printing device, including the above-described automatic conveying mechanism.

[0016] In this invention, the conveying component includes a supporting guide rail and a conveying assembly mounted on the supporting guide rail; the automatic adjustment component is connected to the supporting guide rail and is used to adjust the distance between the two conveying components; the sensing component includes a sensor transmitter and a sensor receiver spaced apart on the supporting guide rail, the sensing component is located between the two conveying components, and is used to detect whether there is an obstruction between the two supporting guide rails. During the process of the automatic adjustment component driving one conveying component to move closer to the other conveying component, the sensing component continuously detects whether there is an obstruction on the path of the conveying component; when there is no obstruction on the path, the sensor receiver can receive the laser emitted by the sensor transmitter, and the automatic adjustment component will continue to drive the conveying component to move. In this embodiment, the design of the sensing component avoids the accident of an obstruction appearing on the path of the conveying component and interfering with it, ensuring the smoothness of the automatic adjustment component driving the two conveying components closer to each other; furthermore, this automatic conveying mechanism has a simple structure and a high degree of automation.

[0026] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides an automatic conveying mechanism, including a sensing component 1, an automatic adjustment component 2, and two conveying components 3 spaced apart. Each conveying component 3 includes a support guide rail 31 and a conveying assembly 32 mounted on the support guide rail 31. The automatic adjustment component 2 is connected to the support guide rail 31 and is used to adjust the distance between the two conveying components 3. It can be understood that the two conveying components 3 can support and convey the workpiece to be conveyed from the left and right sides. The workpiece to be conveyed includes, but is not limited to, circuit boards, trays, etc. The conveying assembly 32 includes, but is not limited to, belt conveyors, etc. The automatic adjustment component 2 includes, but is not limited to, screw and nut assemblies, pneumatic cylinders, and hydraulic cylinders, etc.

[0027] The sensing component 1 includes a sensor transmitter 11 and a sensor receiver 12 spaced apart on the support rail 31. The sensing component 1 is located between the two conveying components 3 and is used to detect whether there is an obstruction between the two support rails 31. Understandably, the sensor transmitter 11 can emit laser light to the sensor receiver 12, and the sensor receiver 12 can receive the laser light emitted by the sensor transmitter 11; the sensor transmitter 11 and the sensor receiver 12 are spaced apart along the length of the support rail 31.

[0028] In this invention, the conveying component 3 includes a support rail 31 and a conveying assembly 32 mounted on the support rail 31; the automatic adjustment component 2 is connected to the support rail 31 and is used to adjust the distance between the two conveying components 3; the sensing component 1 includes a sensor transmitter 11 and a sensor receiver 12 spaced apart on the support rail 31, the sensing component 1 is located between the two conveying components 3, and is used to detect whether there is an obstruction between the two support rails 31. During the process of the automatic adjustment component 2 driving one of the conveying components 3 to move closer to the other conveying component 3, the sensing component 1 detects in real time whether there is an obstruction on the path of the conveying component 3; when there is no obstruction on the path, the sensor receiver 12 can receive the laser emitted by the sensor transmitter 11, and the automatic adjustment component 2 will continue to drive the conveying component 3 to move. In this embodiment, the design of the sensing component 1 avoids the accident of obstruction appearing on the moving path of the conveying component 3 and interfering with the conveying component 3, and ensures the smoothness of the automatic adjustment component 2 driving the two conveying components 3 to approach each other; in addition, the automatic conveying mechanism has a simple structure and a high degree of automation.

[0029] In one embodiment, such as Figure 1 As shown, the automatic adjustment component 2 includes an adjustment motor 21, a lead screw 22, and a nut sleeve 23 mounted on the support guide rail 31. The nut sleeve 23 is threaded onto the lead screw 22, and the adjustment motor 21 is connected to the lead screw 22. Understandably, the lead screw 22 is rotatably mounted between the two support guide rails 31. Specifically, the adjustment motor 21 drives the lead screw 22 to rotate, and the lead screw 22, through the nut sleeve 23, moves one of the support guide rails 31, thereby adjusting the distance between the two conveying components 3. In this embodiment, the automatic adjustment component 2 has a simple structure and low manufacturing cost.

[0030] In one embodiment, such as Figures 1 to 3As shown, the conveying assembly 32 includes a conveying motor 321, a conveyor belt 322, and at least two pulleys 323 rotatably mounted on the support guide rail 31 at intervals. The conveyor belt 322 is wound around all the pulleys 323, and the conveying motor 321 is mounted on the support guide rail 31 and connected to one of the pulleys 323. Understandably, the number of pulleys 323 can be two, three, four, etc., depending on actual needs. Specifically, the conveying motor 321 drives the pulleys 323 to rotate, the pulleys 323 drive the conveyor belt 322 to move, and the conveyor belt 322 moves the items to be conveyed on it through friction. In this embodiment, the conveying assembly 32 has a simple structure and low manufacturing cost.

[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the conveying component 3 also includes a support block 33 mounted on the support guide rail 31, the support block 33 being used to support the conveyor belt 322. Understandably, the support block 33 is located below the upper conveyor belt 322, and the support block 33 supports the workpiece to be conveyed via the conveyor belt 322, thereby ensuring the stability of the conveying component 3 in conveying the workpiece.

[0032] In one embodiment, such as Figure 1 As shown, the automatic conveying mechanism further includes a lifting component 4 installed between the two conveying components 3. The lifting component 4 includes a lifting drive and a top plate 41 installed at the output end of the lifting drive. The lifting drive is used to drive the top plate 41 to rise and fall, so that the top plate 41 pushes away from the conveying component 32 and the conveying component to be conveyed, or so that the conveying component on the top plate 41 is transferred to the conveying component 32. It can be understood that the lifting drive includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a lead screw and nut assembly, etc.

[0033] Specifically, after the two conveying components 3 transport the workpiece to be transported to directly above the top plate 41, the lifting drive component drives the top plate 41 to rise, and the top plate 41 causes the workpiece to be transported to detach from the conveying assembly 32. The processing component processes the workpiece on the top plate 41 (for example, a scraper prints solder paste from the stencil onto the workpiece located on the top plate 41). The lifting drive component drives the top plate 41 to move downward, and the workpiece on the top plate 41 falls onto the conveying assembly 32. The two conveying components 3 then transport the workpiece to the unloading station. In this embodiment, the automatic conveying mechanism has a high degree of automation.

[0034] In one embodiment, such as Figures 1 to 3As shown, the automatic conveying mechanism further includes two clamping components 5, which are mounted one-to-one on the support guide rail 31. Each clamping component 5 includes a clamping drive 51 and a clamping plate 52 mounted on the output end of the clamping drive 51. The clamping drive 51 is mounted on the support guide rail 31 and connected to the clamping plate 52, and is used to drive the clamping plate 52 to clamp the parts to be conveyed on the top plate 41 from opposite ends. It can be understood that the clamping drive 51 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and lead screw and nut assemblies, etc., and the clamping plate 52 is mounted on the support guide rail 31 through a guide rail slider assembly.

[0035] Specifically, after the lifting drive unit drives the conveyor to be transported to detach from the conveyor belt 322 through the top plate 41, the clamping drive unit 51 drives the clamping plates 52 to move closer to each other. The two clamping plates 52 will clamp the conveyor on the top plate 41, thereby ensuring the stability of the conveyor on the top plate 41.

[0036] In one embodiment, such as Figure 1 As shown, the top plate 41 is provided with an insertion slot 411. The automatic conveying mechanism also includes a support member (not shown in the figure) detachably installed in the insertion slot 411. The top plate 41 supports the workpiece to be conveyed through the support member. It can be understood that the insertion slot 411 is located on the top surface of the top plate 41, and the support member includes, but is not limited to, a support pin. The top plate 41 supports the workpiece to be conveyed through the support member, thereby avoiding any accident where the top plate 41 directly contacts the workpiece to be conveyed and scratching it, thus ensuring the processing quality of the workpiece.

[0037] Another embodiment of this utility model provides a printing device, including the above-described automatic conveying mechanism.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
