Description

Technical Field

[0001] This utility model relates to the field of transmission equipment technology, specifically to a bidirectional transmission device and a multi-station warehousing production line. Background Technology

[0002] In modern industrial production, the efficient and stable operation of production lines is a key factor in ensuring enterprise production efficiency. After products are processed and transported at each workstation, they are temporarily stored on buffer shelves. This is an important step in coordinating production rhythm and ensuring the orderly progress of subsequent processes. A reasonable product transfer and storage method can effectively balance the connection between production and warehousing, improving overall production efficiency.

[0003] Currently, the common method for transferring products to buffer shelves in existing production lines is as follows: products completed on the assembly line are moved to hydraulic lifting trolleys via a conveyor line, then lifted to different heights by the hydraulic lifting trolleys, and finally pushed into the corresponding shelves by a transfer mechanism. However, this traditional storage method has many drawbacks, severely restricting the improvement of production efficiency and the control of production costs.

[0004] From a production efficiency perspective, this storage method involves multiple operational steps, each of which requires a certain amount of time. This results in a multi-stage transfer process that is time-consuming. In today's highly competitive market with heavy production demands, a lengthy product transfer process significantly reduces the amount of product processed per unit time, failing to meet the ever-increasing production needs of enterprises and impacting their delivery cycles and market competitiveness.

[0005] In terms of equipment maintenance, hydraulic lifting trucks, as key equipment, experience a gradual deterioration in cylinder sealing performance after prolonged and frequent use, leading to oil leaks. This not only causes instability in the lifting function of the hydraulic lifting truck, affecting the accuracy and reliability of product transfer and increasing the risk of product damage, but also results in wasted hydraulic oil, increased production costs, and environmental pollution, which is inconsistent with the concept of green production. Furthermore, after equipment failure, repairing and replacing sealing components consumes significant manpower, resources, and time, increasing production line downtime and further reducing production efficiency.

[0006] Furthermore, the current hydraulic trolley's positioning roller structure relies solely on the inertia of the assembly line's output to receive the components. This design results in a lack of proactive alignment adjustment capabilities during product transport: when the assembly line's output speed fluctuates or the product's placement angle deviates, the product is prone to inertial misalignment and may not accurately fall into the hydraulic trolley's designated receiving position, sometimes requiring repeated manual adjustments, further extending transport time. Simultaneously, this passive reliance on inertia makes it difficult to match the pace of high-speed production lines, becoming a bottleneck restricting overall efficiency improvement.

[0007] Therefore, the existing method of transferring products to buffer shelves in production lines is significantly inefficient and lacks equipment reliability. There is an urgent need for a new technical solution to shorten product transfer time, improve production efficiency, and avoid a series of problems caused by equipment failure. Summary of the Invention

[0008] Therefore, the technical problem to be solved by this utility model is to overcome the problems of low efficiency and accuracy and single function in the process of transporting components to the buffer rack in the prior art, and to provide a bidirectional transmission device and a multi-station warehouse production line.

[0012] In one embodiment of the present invention, the horizontal transmission component includes two transmission belts, which are arranged in parallel and spaced apart, with an installation space between the two transmission belts.

[0013] In one embodiment of the present invention, the horizontal transmission assembly further includes a one-way limiting member, which is disposed at the transmission end of the transmission belt, and the top of the one-way limiting member is higher than the support surface of the transmission belt.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Example 1:

[0030] See Figure 1 and Figure 2 As shown, this embodiment provides a bidirectional transmission device, which includes: a frame 100; and a lifting transmission assembly 200, which is disposed on the frame 100 and includes a first driver 210 and a ball screw 230. The ball screw 230 includes a screw shaft 231 and a nut 232. The screw shaft extends vertically, with one end connected to the first driver 210 and rotating about its axial direction via the first driver 210. The nut 232 is sleeved and connected to the screw shaft 231 and threadedly engaged with the screw shaft 231 to move along the screw shaft 231. The device includes: a platform 300 connected to the nut 232 and moving synchronously with the nut 232; a horizontal transmission assembly 400 disposed on the platform 300, comprising a second driver 410 and at least one transmission belt 430 connected to the second driver 410, and its support surface moving horizontally via the second driver 410; the element to be transmitted 500 being supported on the support surface of the transmission belt 430, so as to move horizontally via the horizontal transmission assembly 400 and / or move vertically via the lifting transmission assembly 200.

[0031] The bidirectional transmission device described in this embodiment receives the components 500 to be transmitted from the production line via a platform 300. Vertical transmission is achieved through a lifting transmission assembly 200, and / or horizontal transmission is achieved through a horizontal transmission assembly 400. In the lifting transmission process, where stability is relatively poor, this application uses a lead screw instead of a traditional hydraulic structure, further improving stability and safety. Based on this, the transmission device in this application not only improves transmission quality but also achieves high coordination between different transmission cycles, thereby significantly improving transportation efficiency and operational flexibility. Compared to conventional transmission equipment at present, this application has advantages such as wide applicability, ease of operation and control, stable transmission, high precision, and significant improvement in production line efficiency, and has broad application prospects in the industry.

[0032] In this embodiment, the frame 100 provides an installation and connection platform for other structures, thereby improving the overall integration and structural stability of the equipment. The frame 100 includes a horizontal frame 110 and a vertical frame 120. The horizontal frame 110 extends horizontally, with one side connected to the vertical frame 120, and has legs 111 at its bottom. The vertical frame 120 extends vertically, with a lifting rail 121 on its side facing the horizontal frame 110. The platform 300 is slidably connected to the lifting rail 121 via a slider 311. Specifically, in this embodiment, the horizontal frame 110 increases the contact area between the equipment and the mounting surface, while the vertical frame 120 provides lifting and moving space for the platform 300. Furthermore, the connection of the platform 300 to the side of the vertical frame 120 facing the horizontal frame 110 also helps maintain the overall central stability of the equipment.

[0033] See Figure 3 As shown, the lifting assembly in this embodiment further includes a coupling 220, which is disposed between the working end of the first driver 210 and the ball screw 230. Specifically, the first driver 210 serves as a power source, driving the screw shaft 231 of the ball screw 230 to rotate by outputting torque. The screw shaft 231 is preferably a rotary motor. As a rotating component, the screw shaft 231 converts the rotational motion of the motor into the linear motion of the nut 232. In the industry, the thread lead accuracy of its surface can reach ±0.005mm / m, thereby ensuring high precision of the linear motion. The nut 232 can convert rotational motion into its own linear motion by engaging with the thread raceway of the screw shaft 231 through its internal balls. The coupling 220 connects the output shaft of the first driver 210 and the screw shaft 231, transmitting torque and compensating for coaxiality errors between the two shafts. Based on the above structural configuration, the lifting drive scheme in this embodiment has higher efficiency and better transmission stability compared to traditional hydraulic or pneumatic lifting.

[0034] See Figure 4As shown, the horizontal transmission component 400 in this embodiment is used to receive front-end input components or to input components on the horizontal transmission component 400 into back-end devices. In addition, it can also achieve uniform arrangement between components through the transmission belt 430 to reduce component damage. Specifically, the horizontal transmission assembly 400 further includes a transmission mechanism 420. The transmission belt 430 is connected to the second driver 410 through the transmission mechanism 420. The transmission mechanism 420 includes a connecting rod 421, a rack 423, a driving wheel 424, two gears 422, and at least one driven wheel 425. One of the gears 422 is sleeved on the working end of the second driver 410, and the other gear 422 is sleeved on the connecting rod 421. The rack 423 is sleeved on the two gears 422 and meshes with the two gears 422 respectively. The driving wheel 424 and the driven wheel 425 are arranged in a straight line on the platform 300. The two ends of the transmission belt 430 are respectively sleeved on the outer surfaces of the driving wheel 424 and the driven wheel 425. The end of the connecting rod 421 passes through and connects to the driving wheel 424 to drive the support surface of the transmission belt 430 to move. The second driver 410 is also preferably a rotary motor, whose output end drives the rack 423 through the gear 422, and then drives the connecting rod 421 through the rack 423 and another gear 422, thereby achieving the purpose of driving the drive wheel 424 to rotate.

[0035] Furthermore, the horizontal transmission assembly 400 in this embodiment includes two transmission belts 430, which are arranged in parallel and spaced apart, with an installation space between them. The second driver 410 and the transmission mechanism 420 are both disposed in the installation space. This structural design improves the space utilization of the device and enables a more stable transmission process for the components through the two transmission belts. Correspondingly, in this embodiment, the two transmission belts 430 are synchronously driven by two drive wheels 424 connected at both ends of a connecting rod 421.

[0036] Furthermore, the horizontal conveying assembly 400 in this embodiment also includes a one-way limiting member 426. The one-way limiting member 426 is disposed at the conveying end of the conveyor belt 430, and the top of the one-way limiting member 426 is higher than the support surface of the conveyor belt 430. The limiting member 426 utilizes the height difference between its top and the support surface of the conveyor belt 430 to form a physical barrier. Therefore, when the conveyor belt 430 stops or reverses its movement, the vertical blocking surface of the limiting member 426 can prevent material from sliding in the opposite direction.

[0037] See Figure 4 and Figure 5As shown, the platform 300 in this embodiment includes a frame 310 and an assembly frame 320. The frame 310 extends horizontally and is fixedly connected to the nut 232. The assembly frame 320 is supported on the frame 310, and the horizontal transmission component 400 is disposed inside the assembly frame 320. Specifically, the frame 310 is used to achieve a stable connection with the nut 232, and the assembly frame 320 is used to provide a support platform for the horizontal transmission component 400 and the transmission element. Further, the assembly frame 320 includes a vertically connected base plate 321 and a side plate 322. The base plate 321 is supported on the frame 310 and has weight-reduction holes. Further, in this embodiment, the second driver 410 is disposed on the base plate 321, and the driving wheel 424 and the driven wheel 425 are connected to the side plate 322. In different embodiments, the platform 300 can be configured with different shapes or structures according to actual usage requirements, and this utility model does not impose specific limitations on this.

[0038] The bidirectional transmission device in this embodiment also includes a control mechanism, and the lifting transmission component 200 and the horizontal transmission component 400 are respectively connected to the control mechanism. In actual production and processing, operators can use the control mechanism to adjust the above structure in real time, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment.

[0039] Example 2:

[0040] This embodiment provides a multi-station storage production line, which includes the bidirectional transmission equipment, front-end processing equipment, back-end processing equipment, and multi-layer storage warehouse described in Embodiment 1. The multi-layer storage warehouse is disposed between the front-end processing equipment and the back-end processing equipment, and the bidirectional transmission equipment is disposed between the front-end processing equipment and the multi-layer storage warehouse.

[0041] In summary, the bidirectional transmission equipment and multi-station storage production line described in this utility model receive the components 500 to be transmitted from the production line via a platform 300. Vertical transmission is achieved through a lifting transmission assembly 200, and horizontal transmission is achieved through a horizontal transmission assembly 400. In the lifting transmission process, where stability is relatively poor, this application uses a lead screw instead of a traditional hydraulic structure, further improving stability and safety. Based on this, the transmission equipment in this application not only improves transmission quality but also achieves high coordination between different transmission cycles, thereby significantly improving transportation efficiency and operational flexibility. Compared to conventional transmission equipment at present, this application has advantages such as wide applicability, ease of operation and control, stable transmission, high precision, and significant improvement in production line efficiency, and has broad application prospects in the industry.
