Description

Technical Field

[0001] The invention relates to the technical field of parts conveying, and in particular to a chain plate conveying mechanism for parts production. Background Art

[0002] In the field of parts production, the chain conveyor mechanism is an indispensable transmission equipment in the automated assembly line, especially in the continuous conveying process of precision parts (such as electronic components, miniature bearings, etc.), it is necessary to ensure that the parts move smoothly and without scattering. Traditional chain conveyors mostly adopt a single-layer chain-driven chain plate structure, and the chain plates are rigidly connected to form a continuous conveying surface. However, this type of design has significant defects: 1. Gap drop problem: The gap between the chain plates caused by assembly tolerance or operation wear can easily cause small parts to fall, causing material loss or even equipment jamming. 2. Insufficient dynamic sealing: Some equipment attempts to fill the gap between the chain plates with fixed baffles, but they cannot adapt to the dynamic deformation of the chain plates during movement, especially when changing speed, it is easy to form local gaps. 3. Poor transmission synchronization: When multiple chains are driven, if the sprocket tooth phase is not accurately matched, the chain plate will be misaligned, exacerbating the gap problem and affecting the flatness of the conveying surface. 4. Applicability limitations: The existing conveying mechanism lacks width adjustment function, and it is difficult to adapt to the transmission needs of parts of different sizes. Frequent tooling changes are required, reducing production efficiency.

[0003] Therefore, there is an urgent need for a chain conveying mechanism that can dynamically seal the chain gap, realize precise synchronous transmission of multiple chains, and have the ability to adaptively adjust the conveying width to meet the production needs of high-precision and multi-specification parts. Summary of the invention

[0004] The main purpose of the present invention is to provide a chain plate conveying mechanism for parts production which can prevent small parts from falling from the gaps between plate chains.

[0005] In order to achieve the above object, the technical solution provided by the present invention is:

[0006] A chain plate conveying mechanism for part production, comprising two support plates. A conveying space is formed between the two support plates. A driving member is rotatably connected to each of the left and right sides within the conveying space. A driven member is rotatably connected to the conveying space below each driving member. The driving member and the driven member are connected by two first chains in a driving manner. The two driving members are connected by two second chains in a driving manner. The two second chains are located between the two first chains. The outer sides of the two first chains are connected by a plurality of first chain plates. The outer sides of the two second chains are connected by a plurality of second chain plates. The first chain plates above the first chains and the second chain plates above the second chains are arranged in a staggered manner. After the first chain plate moves above the first chain, it can be located between two adjacent second chain plates above the second chain. Telescopic plates are elastically and slidably fitted on both sides in the movement direction of the first chain plate and the second chain plate. The telescopic plates between the adjacent first chain plate and the second chain plate above the first chain and the second chain are in contact with each other and are squeezed.

[0007] Specifically, the upper ends of the first chain plates and the second chain plates above the first chain and the second chain are flush.

[0008] Specifically, the driving member includes an upper rotating shaft which is rotatably connected to the support plate. The driven member includes a lower rotating shaft which is rotatably connected to the support plate. Two first sprockets are concentrically fixed on both the upper rotating shaft and the lower rotating shaft. The front first sprocket and the rear first sprocket are respectively connected by two first chains in a driving manner. Two second sprockets are fixed on the upper rotating shaft. The second sprockets are located inside the first sprockets. The front second sprocket and the rear second sprocket are respectively connected by two second chains in a driving manner. A driving motor is fixed on one of the support plates. The driving motor is in transmission connection with one of the lower rotating shafts.

[0009] Specifically, the teeth of the first sprockets and the second sprockets on the upper rotating shaft are arranged in a staggered manner.

[0010] Specifically, the first chain and the second chain have the same structure. The first chain is formed by connecting a plurality of first chain links and a plurality of second chain links end to end. The first chain links and the second chain links of the first chain are arranged in an alternating manner. The second chain is formed by connecting a plurality of first chain links and a plurality of second chain links end to end. The first chain links and the second chain links of the second chain are arranged in an alternating manner. Engaging grooves are provided on the first chain links. The first chain links of the first chain are engaged with the teeth of the first sprockets. The first chain links of the second chain are engaged with the teeth of the second sprockets. When the first chain links of the first chain are engaged with the teeth of the upper first sprockets, the first chain links of the second chain are engaged with the teeth of the second sprockets. The first chain links engaged with the upper first sprockets and the first chain links engaged with the second sprockets are arranged in a staggered manner in the circumferential direction of the upper rotating shaft.

[0011] Specifically, a mounting plate is fixed on the first link. The first link plate is fixedly connected to the first link of the first chain through the mounting plate, and the second link plate is fixedly connected to the first link of the second chain through the mounting plate.

[0012] Specifically, sliding grooves are formed on both sides of the first link plate and the second link plate in the moving direction. The telescopic plate is slidably arranged in the sliding groove. One end of the telescopic plate is located outside the sliding groove. One end of the telescopic plate in the sliding groove is connected to the bottom of the sliding groove through a spring, and one end of the telescopic plate outside the sliding groove is arc-shaped.

[0013] Specifically, the upper ends of the two support plates are fixedly connected to the electric slide rail. The lower ends of the two sliding parts of the electric slide rail are both fixedly connected with limit plates. The two limit plates are located between the two support plates. The sliding direction of the sliding part is perpendicular to the transmission direction of the parts, and the length direction of the limit plate is parallel to the conveying direction of the parts.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. Through the staggered arrangement of the first link plate and the second link plate, the first link plate is inserted between adjacent second link plates to form a continuously covered conveying surface, physically reducing the static gap between the link plates.

[0016] 2. When adjacent telescopic plates are squeezed against each other, a dynamic seal is formed. Even if the link plates are slightly misaligned due to movement, they can maintain close contact through elastic compensation, preventing small parts from falling through the gap. The arc-shaped end of the telescopic plate guides the sliding during contact, reducing the frictional resistance and ensuring the smoothness of the sealing action, avoiding jamming.

[0017] 2. The first chain and the second chain are driven in cooperation. The first chain and the second chain are precisely matched through the tooth misalignment of the first sprocket and the second sprocket, ensuring that the movement phase difference between the first link plate and the second link plate is controllable. The alternating design of the first link and the second link ensures the synchronism of the first link plate and the second link plate during movement, avoiding misalignment between the first link plate and the second link plate or the expansion of the gap between them due to asynchronous transmission.

[0018] 4. The upper ends of the first link plate and the second link plate are flush, forming a uniform conveying plane, improving the stability of part conveying and reducing the risk of jolting or tilting.

[0019] 5. By driving the limit plates to move through the electric slide rail, the distance between the two limit plates can be adjusted in real time to adapt to the conveying requirements of parts of different sizes without stopping the machine to replace the tooling. The length direction of the limit plate is parallel to the conveying direction. While adjusting the width, it continuously guides the parts to prevent the parts from shifting or piling up, especially suitable for the directional conveying of precision parts.

[0020] 6. The present invention has the functions of dynamic sealing and conveying width adjustment between the first chain plate and the second chain plate, enabling it to be widely applied to the conveying of micro parts, shaped parts or easily rolling objects, and solving the limitations of traditional chain plate machines due to fixed gaps. The telescopic plate that can elastically slide can cope with working conditions of high speed, variable speed or load fluctuation, maintain stable conveying performance, and reduce the risk of part damage.

Detailed Embodiment

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] As Figures 1-8 shown, a chain plate conveying mechanism for part production includes two support plates 1, and a conveying space is formed between the two support plates 1.

[0032] On both the left and right sides within the conveying space, there is a driving member connected in a rotatable manner. Within the conveying space below the driving member, there is a driven member connected in a rotatable manner.

[0038] A driving motor is fixed on one of the support plates 1, and the driving motor is in transmission connection with one of the lower rotating shafts 4.

[0039] The first chains 8 and the second chains 9 have the same structure.

[0040] The first chain 8 is formed by connecting a plurality of first chain links 10 and a plurality of second chain links 11 end to end. The first chain links 10 and the second chain links 11 of the first chain 8 are arranged in an alternating manner.

[0041] The second chain 9 is formed by connecting a plurality of first chain links 10 and a plurality of second chain links 11 end to end. The first chain links 10 and the second chain links 11 of the second chain 9 are arranged in an alternating manner.

[0042] Engaging grooves are provided on the first chain links 10. The first chain links 10 of the first chain 8 are engaged with the teeth of the first sprockets 6. The first chain links 10 of the second chain 9 are engaged with the teeth of the second sprockets 7.

[0043] When the first chain links 10 of the first chain 8 are engaged with the teeth of the upper first sprockets 6, the first chain links 10 of the second chain 9 are engaged with the teeth of the second sprockets 7.

[0044] The first chain links 10 engaged with the upper first sprockets 6 and the first chain links 10 engaged with the second sprockets 7 are arranged in a staggered manner in the circumferential direction of the upper rotating shaft 5.

[0045] The outer sides of the two first chains 8 are connected by a plurality of first chain plates 14. The outer sides of the two second chains 9 are connected by a plurality of second chain plates 15.

[0046] The first chain plate 14 above the first chain 8 and the second chain plate 15 above the second chain 9 are arranged in a staggered manner.

[0047] After the first chain plate 14 moves to above the first chain 8, it can be located between two adjacent second chain plates 15 above the second chain 9. The upper ends of the first chain plate 14 and the second chain plate 15 above the first chain 8 and the second chain 9 are flush.

[0048] An installation plate 12 is fixed on the first link 10. The first chain plate 14 and the first link 10 of the first chain 8 are fixedly connected through the installation plate 12. The second chain plate 15 and the first link 10 of the second chain 9 are fixedly connected through the installation plate 12.

[0049] The second chain plate 15 rotated to above the second chain 9 can fill the space between two adjacent first chain plates 14 above the first chain 8.

[0050] Elastic sliding fit telescopic plates 16 are arranged on both sides in the movement direction of the first chain plate 14 and the second chain plate 15. The telescopic plates 16 between the adjacent first chain plate 14 and the second chain plate 15 above the first chain 8 and the second chain 9 are in contact with each other and are squeezed.

[0051] Chute grooves are provided on both sides in the movement direction of the first chain plate 14 and the second chain plate 15.

[0053] After the driving motor is started, the first chain 8 and the second chain 9 can drive the first chain plate 14 and the second chain plate 15 to rotate respectively. The second chain plate 15 rotated to above the second chain 9 can fill the space between two adjacent first chain plates 14 above the first chain 8. After placing the parts on the upper ends of the first chain plate 14 and the second chain plate 15, the parts can be conveyed.

[0054] Start the electric slide rail 2. The electric slide rail 2 causes the two sliding parts to approach or move away from each other. When the sliding parts move, they drive the limit plate 3 to move. During the process of the two sliding parts approaching or moving away from each other, the distance between the two limit plates 3 can be adjusted, and the parts can be limited in the front-back direction during the transportation process.

[0055] When the second link plate 15 is filled between two adjacent first link plates 14, under the guiding action of the arc-shaped end of the telescopic plate 16, the two adjacent telescopic plates 16 can slide into their respective chutes respectively. At the same time, the spring 13 is compressed. Under the action of the adjacent two telescopic ends pressing against each other, when transporting parts with a smaller volume, it can prevent small parts from falling between the adjacent first link plate 14 and the second link plate 15.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
