Description

Technical Field

[0001] This utility model relates to the field of automated transmission technology for automotive parts, specifically to a conveyor belt transition transmission device for constant velocity drive shaft parts. Background Technology

[0002] Currently, in automated transmission systems for constant velocity drive shaft components in automobiles, the industry commonly employs the following three technical solutions for the connection and transition between two conveyor belts, but each has its own application limitations:

[0003] 1) Connecting plate solution: This solution uses a connecting plate at the junction of two conveyor belts to achieve natural sliding transition by the weight of the parts themselves. However, due to factors such as the surface condition of the parts and the coefficient of friction of the connecting plate material, the parts are prone to stagnation in the connecting area due to excessive friction, which directly leads to the interruption of the transmission process and seriously restricts the overall transmission efficiency.

[0004] 2) Gravity self-sliding scheme: This scheme relies entirely on the tilt angle of the conveyor belt and the self-weight of the parts to drive the sliding. However, when the transmission shaft parts have a high center of gravity, they are very prone to tipping over during the sliding process due to the imbalance of the center of gravity. This will not only cause collision damage to the parts, but may also damage the equipment, significantly increasing the risk of production interruption and the cost of material loss.

[0005] 3) Material distribution cylinder and pusher cylinder solution: This solution improves the stability of transmission in right-angle docking scenarios of conveyor belts by combining material distribution cylinders and pusher cylinders. However, it is costly, requiring multiple sets of cylinder actuators and corresponding pneumatic control modules and sensor components, which significantly increases the cost of equipment procurement and subsequent maintenance. At the same time, its applicability is limited. This solution is only for right-angle docking scenarios and cannot meet the more common horizontal docking requirements of conveyor belts. It is also completely unsuitable for compact layouts where space is limited and it is impossible to install segmentation cylinders.

[0006] In summary, the industry urgently needs a solution that balances the three core requirements of low cost, high compatibility, and high reliability to achieve reliable transmission of horizontally docking conveyor belts. Utility Model Content

[0028] The basic working principle of the conveyor belt transition transmission device for constant velocity drive shaft parts involved in this utility model is as follows: By setting up a mounting bracket 1, a composite roller mechanism 2, a transmission mechanism 3, and a power source 4, the transmission device is placed in the reserved space between two conveyor belts during use. The length of the reserved space can be set to 100mm. Specifically, the two conveyor belts can be horizontally or vertically connected. When the two conveyor belts are horizontally connected, the inlet direction of the mounting bracket 1 is close to the outlet direction of one conveyor belt, and the outlet direction of the mounting bracket 1 is close to the inlet direction of the other conveyor belt. When the two conveyor belts are vertically connected, the inlet direction of the mounting bracket 1 is close to the outlet direction of one conveyor belt, and the outlet direction of the mounting bracket 1 is close to the side of the other conveyor belt. By setting up the mounting bracket 1, the stability of the overall structure can be enhanced, supporting the composite roller mechanism 2, the transmission mechanism 3, the power source 4, etc., and avoiding vibration interference between the various mechanisms. By setting up the power source 4 and the transmission mechanism 3, the power source 4 can drive the drive shaft 301 and the active... The drive wheel 303 rotates, and through the synchronous belt 305, the drive wheel 303 can further drive the driven wheel 304 and the output wheel 302 to rotate, thereby driving the two drive wheels, N output wheels 302, and N first rollers 201 to rotate. By setting the synchronous belt 305, the rotational speeds of the drive wheel 303, driven wheel 304, and output wheel 302 can be synchronized, preventing parts from sliding and being obstructed. When the two drive rollers 203 and the N first rollers 201 rotate, the constant velocity drive shaft parts can be transported from the conveyor belt in the inlet direction to the conveyor belt in the outlet direction. The first rollers 201 can provide a guiding function for the constant velocity drive shaft parts to prevent them from tilting, the second rollers 202 can provide support for the constant velocity drive shaft parts, and the drive rollers 203 can enhance the power. At the same time, by setting the diameter of the first rollers 201 to be larger than the diameter of the second rollers 202, the distance between the first rollers 201 and their adjacent second rollers 202 can be reduced, preventing the constant velocity drive shaft parts from tipping over.

[0029] See Figures 1 to 3 The present invention will be further described below with reference to a specific embodiment:

[0030] In this embodiment, see Figure 1 , Figure 2 , Figure 3As a preferred design, the mounting bracket 1 also includes a first transition plate 7 in the inlet direction and a second transition plate 8 in the outlet direction. The first transition plate 7 is located between the drive roller 203 and the conveyor belt, and the upper surfaces of the first transition plate 7 and the constant velocity drive shaft parts, as well as the upper surfaces of the drive roller 203 and the constant velocity drive shaft parts, are located on the same horizontal plane. One end of the second transition plate 8 is bolted to the first mounting plate 101, and the other end is bolted to the second mounting plate 102. The second transition plate 8 is located between the first roller 201 and the conveyor belt. The upper surfaces of the second transition plate 8 and the constant velocity drive shaft parts, as well as the upper surfaces of the first roller 201 and the constant velocity drive shaft parts, are all located on the same horizontal plane. The first transition plate 7 and the second transition plate 8 include various width dimensions, and different width dimensions of the first transition plate 7 and the second transition plate 8 can be installed according to the actual situation, thereby adjusting the gap between the transmission device and the conveyor belts on both sides. That is, the gap between the drive roller 203 and the conveyor belt can be adjusted, and the gap can be adjusted between 10-20mm. This can adapt to parts of different sizes and ensure stable transition of the constant velocity drive shaft parts.

[0031] In this embodiment, see Figure 3 As a preferred design, the power source 4 is set as a DC servo motor. DC servo motors have the advantages of fast dynamic response, agile start and stop, smooth operation, and good environmental adaptability.

[0032] In this embodiment, see Figure 1 As a preferred design, it also includes a remote controller for controlling the DC servo motor. The remote controller is electrically connected to the DC servo motor, which can overcome spatial limitations, achieve flexible operation, facilitate long-distance operation, and facilitate centralized management of multiple transmission devices. Preferably, the remote controller can be set as a PLC controller.

[0033] In this embodiment, see Figure 1 , Figure 2As a preferred design, it also includes a through-beam photoelectric sensor for detecting constant velocity drive shaft parts. The through-beam photoelectric sensor includes a transmitter fixedly mounted on the first mounting plate 101 and a receiver fixedly mounted on the second mounting plate 102. The transmitter and receiver are electrically connected to a remote controller. The through-beam photoelectric sensor is located in the inlet direction of the mounting bracket 1 and is positioned between the first transition plate 7 and the conveyor belt. The through-beam photoelectric sensor has high detection accuracy and strong interference resistance, as well as good energy saving effect and service life. In use, when the constant velocity drive shaft parts reach the transition area between the first transition plate 7 and the conveyor belt, they can be detected by the through-beam photoelectric sensor. At this time, the through-beam photoelectric sensor transmits the detection signal to the remote controller, which controls the DC servo motor to start, thereby driving the composite roller mechanism 2 to move and complete the conveying of the constant velocity drive shaft parts.

[0034] In this embodiment, see Figure 1 , Figure 2 , Figure 3 As a preferred design, the transmission mechanism 3 is also equipped with a protective cover 6. The transmission shaft 301, the driving wheel 303, the driven wheel 304, the N output wheels 302, and the multiple synchronous belts 305 are all located in the inner cavity of the protective cover 6. On the one hand, it can prevent the staff from accidentally touching the transmission mechanism 3 and causing injury. On the other hand, it can effectively isolate the external environment from the corrosion of the transmission mechanism 3, reduce failures, and lower maintenance costs.

[0035] In this embodiment, see Figure 1 , Figure 3 As a preferred design, it also includes a base 5, with the mounting bracket 1 fixedly disposed on the top of the base 5. The base 5 has an inner cavity, and the power source 4 is fixedly disposed in the inner cavity of the base 5. On the one hand, it can support the mounting bracket 1, and on the other hand, it can protect the power source 4.

[0036] In this embodiment, see Figure 1 As a preferred design, the outer circumferential surfaces of the N first rollers 201 and the two drive rollers 203 are all knurled, which can significantly increase their surface friction, reduce power transmission loss, and avoid part conveying failure due to slippage. At the same time, compared with smooth surfaces, the knurled first rollers 201 and drive rollers 203 are more wear-resistant and can extend their service life.

[0037] In this embodiment, the transmission device of this application is compared with the traditional connecting plate solution and the cylinder pushing solution:

[0038]

[0039]

[0040] As can be seen from the above, the conveyor belt transition transmission device for constant velocity transmission shaft parts of this utility model has the following beneficial effects:

[0041] By setting up a composite roller mechanism 2, with the first roller 201 and the second roller 202 arranged alternately (i.e., large and small rollers arranged alternately), both load-bearing and guiding functions can be taken into account, solving the stagnation problem of traditional solutions. By setting up a transmission mechanism 3 and a power source 4, the scheme of driving and synchronous transmission through the power source 4 replaces the cylinder in the traditional solution, which can greatly reduce the cost of the overall device and is applicable to various working conditions. By setting up a mounting bracket 1, the composite roller mechanism 2, transmission mechanism 3, power source 4 and other mechanisms can be supported, enhancing the stability of the overall structure. Through the transition transmission device of this application, it can adapt to the docking of two conveyor belts in various working conditions such as horizontal and right angle, and can effectively ensure the stable and efficient transition transmission of constant velocity transmission shaft parts.

[0042] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
