Description

Technical Field

[0001] This utility model relates to the field of conveyor rail technology, and in particular to a bidirectional guide rail assembly. Background Technology

[0002] Currently, with the rapid development and iterative upgrading of industrial technology, guide rails, as a key mechanical transmission component, are finding increasingly wide applications. They play a crucial role in numerous fields such as automated production lines, logistics and warehousing equipment, and precision machine tools. Achieving precise movement of goods using guide rails has become a widely adopted and reliable technology in modern industrial production. It ensures that goods maintain a stable trajectory and high precision during movement, thus meeting the needs of various complex processes and production flows. However, conventional guide rails have certain design limitations; most can only move in one fixed direction. When goods need to move along a path opposite to the direction of movement of the guide rail, it is often necessary to install an additional guide rail to accomplish this task.

[0003] Adding guide rails to accommodate reverse movement results in material waste. Conventional guide rails allow for unidirectional movement; what could be accomplished with one set now requires two or more sets, significantly increasing material costs. Adding guide rails also occupies space, a problem exacerbated in space-constrained scenarios such as small automated equipment and compact production lines. Furthermore, more guide rails complicate component handling and installation, increasing both manufacturing costs and maintenance difficulty, leading to further resource waste.

[0004] Patent document CN215363387U discloses a bidirectional guide rail, including a main frame, a driven wheel mechanism, a driving wheel mechanism, a guide mechanism, and proximity switches. The main frame includes an optical axis, positioning mounting holes, driven wheel mounting holes, and driving mechanism mounting holes. The driven wheel mechanism is located at the right end of the main frame, and the driving wheel mechanism is located at the left end of the main frame. The guide mechanism includes a synchronous belt and a movable guide plate. The movable guide plate is connected to the driving wheel and the driven wheel respectively via the synchronous belt. The proximity switches are located at the center of the front end and the right side of the front end of the main frame. This utility model provides users with a compact, precise, and reciprocating bidirectional guide rail by means of two guide mechanisms, a synchronous belt clamped inside the two guide mechanisms corresponding to each other, a driving motor driving the driving wheel, and the driven wheel being driven by the driving wheel via the synchronous belt, and a movable clamp cooperating with the synchronous belt.

[0005] As in the prior art of the aforementioned patent, the patent discloses the use of bidirectional guide rails to transport objects at both ends. However, when the two carrier mechanisms move to the middle position of the bidirectional guide rails, this patent does not disclose how to exchange the objects on the two carrier mechanisms. In the prior art, most of them are clamped by a robotic arm to move the object on one carrier mechanism to the other carrier mechanism, and then the two carrier mechanisms slide to the two ends of the bidirectional guide rails respectively to transport the objects. However, the above-mentioned exchange process by robotic arm consumes a lot of time, reduces the transmission efficiency, and increases the manufacturing and operating costs of the equipment. Utility Model Content

[0006] Purpose of the utility model: The purpose of this utility model is to provide a bidirectional guide rail assembly to overcome the above-mentioned shortcomings in the prior art.

[0007] Technical solution: A bidirectional guide rail assembly includes a bidirectional conveying component. The bidirectional conveying component includes a slide rail and two conveying blocks slidably mounted on the slide rail. Two air suction holes are respectively opened at the top of the two conveying blocks. Sliding members are slidably adapted and connected to the two conveying blocks. A carrying chamber is fixedly installed at the top of the sliding member. The carrying chamber and the sliding member are respectively arranged opposite to each other. A suction component is provided on the conveying block. The width of the carrying chamber and the sliding member are equal and set to twice the length of the conveying block.

[0008] As a further description of the above technical solution: the sliding member is configured as L-shaped, the horizontal end of the sliding member corresponds to one of the air intake holes on the conveying block, and the vertical end of the sliding member abuts against the sliding member.

[0009] As a further description of the above technical solution: a plug-in block is fixedly installed at the horizontal end of the sliding member, a limit block is fixedly installed at the bottom of the vertical end of the sliding member, limit grooves that are compatible with the limit blocks are opened on both sides of the slide rail, and plug-in grooves for plugging into two oppositely arranged plug-in blocks are opened at the top of the two conveying blocks.

[0010] As a further description of the above technical solution: the bidirectional conveying assembly also includes a slide groove formed at the top of the slide rail, a bidirectional screw is rotatably installed inside the slide groove, and two threads of the bidirectional screw are respectively threadedly connected to sliders. The two sliders are respectively fixedly connected to the bottom ends of two conveying blocks. A motor is fixedly installed at one end of the slide rail, and the output end of the motor is connected to the bidirectional screw drive.

[0011] As a further description of the above technical solution: the suction assembly includes a mounting plate fixedly installed on one side of the conveying block. A vacuum pump and a three-way solenoid valve are fixedly installed on the top of the mounting plate. The input end of the vacuum pump is connected to the output end of the three-way solenoid valve, and an exhaust pipe is connected to the output end of the vacuum pump.

[0015] Beneficial effects: The object to be transported is placed inside the carrying chamber at one end. Then, the two transport blocks are connected by a bidirectional transport assembly. Since the width of the carrying chamber and the sliding component is equal and set to twice the length of the transport block, when the two transport blocks are connected, the two carrying chambers and the sliding component are also respectively positioned above the two transport blocks. At this time, the suction components on the two transport blocks adsorb the carrying chambers and sliding components at opposite positions, realizing the exchange of the two carrying chambers and sliding components on the two transport blocks. Then, the two transport blocks are moved to both ends of the slide rail by the bidirectional transport assembly, thereby realizing the transport of the object along with the carrying chamber at one end of the slide rail to the other end of the slide rail. This realizes the exchange of carrying chambers. This device can not only be used to transport objects from one end to the other, but also realize the exchange of objects at both ends through the carrying chambers. Attached Figure Description

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figure 1-6 A bidirectional guide rail assembly includes a bidirectional conveying component. The bidirectional conveying component includes a slide rail 1 and two conveying blocks 6 slidably mounted on the slide rail 1. Each of the two conveying blocks 6 has two suction holes 20 at its top. Sliding members 8 are slidably connected to each of the two conveying blocks 6. A carrying chamber 9 is fixedly mounted on the top of each sliding member 8. The carrying chamber 9 and the sliding member 8 are respectively arranged opposite to each other. A suction component is provided on each conveying block 6. The width of the carrying chamber 9 and the sliding member 8 is equal and twice the length of the conveying block 6. The object to be conveyed is placed inside the carrying chamber 9 at one end, and then the two conveying blocks 6 are connected by the bidirectional conveying component. Because the carrying chamber 9 and the sliding member 8 are slidably connected, the conveying components 20 and 30 are slidably mounted on the top of each conveying block 6. The width of component 8 is equal and set to twice the length of conveying block 6. When the two conveying blocks 6 are connected, the two carrying chambers 9 and the sliding component 8 are also respectively set above the two conveying blocks 6. At this time, the suction components on the two conveying blocks 6 adsorb the carrying chambers 9 and the sliding component 8 at opposite positions, realizing the exchange of the two carrying chambers 9 and the sliding component 8 on the two conveying blocks 6. Then, the two conveying blocks 6 are moved to both ends of the slide rail 1 by the bidirectional conveying component, thereby realizing the movement of the object at one end of the slide rail 1 along with the carrying chamber 9 to the other end of the slide rail 1, realizing the conveying of the object. In this process, the exchange of carrying chambers 9 is realized. This device can not only be used to convey objects from one end to the other end, but also realize the exchange of objects at both ends through the carrying chambers 9.

[0026] As a preferred technical solution in this embodiment, the sliding member 8 is configured as an L-shape, with the horizontal end of the sliding member 8 corresponding to one of the suction holes 20 on the conveying block 6, and the vertical end of the sliding member 8 abutting against the sliding member 8; the sliding member 8 and the bearing chamber 9 can be adsorbed through one of the suction holes 20, so that the sliding member 8 and the bearing chamber 9 can be stably fixed on the conveying block 6. Its principle is the same as that of a vacuum suction cup, which generates negative pressure by suction to fix the object.

[0027] As a preferred technical solution of this embodiment, a plug-in block 12 is fixedly installed at the horizontal end of the sliding member 8, and a limiting block 13 is fixedly installed at the bottom of the vertical end of the sliding member 8. Limiting grooves 10 that are adapted to the limiting blocks 13 are opened on both sides of the slide rail 1. The top ends of the two conveying blocks 6 are provided with plug-in grooves 11 for plugging into the two plug-in blocks 12 that are arranged opposite to each other. The plug-in grooves 11 and the limiting grooves 10 are opened to increase the stability of the connection between the sliding member 8 and the conveying block 6. In addition to being fixed by negative pressure suction, the limiting grooves 10 and the plug-in grooves 11 can also limit the sliding member 8 in the longitudinal direction, further increasing the stability of the bearing chamber 9.

[0028] As a preferred embodiment, the bidirectional conveying assembly further includes a slide groove 3 formed at the top of the slide rail 1. A bidirectional screw 4 is rotatably installed inside the slide groove 3. The two threads of the bidirectional screw 4 are respectively threadedly connected to sliders 5. The two sliders 5 are respectively fixedly connected to the bottom ends of the two conveying blocks 6. A motor 2 is fixedly installed at one end of the slide rail 1. The output end of the motor 2 is connected to the bidirectional screw 4 for transmission. The motor 2 drives the bidirectional screw 4 to rotate forward or backward. The forward and reverse rotation of the bidirectional screw 4 can enable the two sliders 5 to drive the conveying blocks 6 to move towards the center or to both sides.

[0029] As a preferred technical solution of this embodiment, the suction assembly includes a mounting plate 14 fixedly installed on one side of the conveying block 6. A vacuum pump 15 and a three-way solenoid valve 16 are fixedly installed on the top of the mounting plate 14. The input end of the vacuum pump 15 is connected to the output end of the three-way solenoid valve 16, and an exhaust pipe 17 is connected to the output end of the vacuum pump 15. The vacuum pump 15 and the three-way solenoid valve 16 are both existing technologies. The three-way solenoid valve 16, the vacuum pump 15, and the motor 2 are all connected to an external control system. The three-way solenoid valve 16 can control the opening and closing of one of the two input ends or the full opening and closing of both input ends, thereby controlling the suction holes 20 at the top of the two conveying blocks 6 to simultaneously suck air or suck air only through one suction hole 20. Combined with the response of the control system under different working conditions, the exchange of the carrying chamber 9 in the middle position is realized. The two carrying chambers 9 can also be fixed at the top of one conveying block 6 simultaneously when the three-way solenoid valve 16 is fully open, realizing the unidirectional conveying of a large number of objects.

[0030] As a preferred technical solution in this embodiment, the two input ends of the three-way solenoid valve 16 are respectively connected to a first extraction tube 18 and a second extraction tube 19, and the first extraction tube 18 and the second extraction tube 19 are respectively connected to two suction holes 20.

[0031] As a preferred technical solution of this embodiment, the conveying block 6 has two connecting channels 21 respectively. One of the connecting channels 21 is connected to one of the air intake holes 20 and the first extraction pipe 18 at both ends, and the other connecting channel 21 is connected to another air intake hole 20 and the second extraction pipe 19 at both ends respectively. The first extraction pipe 18 and the second extraction pipe 19 can draw air from the two air intake holes 20 respectively through the connecting channel 21.

[0032] As a preferred technical solution of this embodiment, the first extraction tube 18 and the second extraction tube 19 are provided with a barrier net 22 at the top end; the barrier net 22 is provided to prevent foreign objects from falling into the air intake hole 20 and avoid affecting the air intake process.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
