[0022] It should be noted that the terms "first," "second," and the like in this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the disclosure described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0023] See also Figures 1 to 5In an embodiment of the utility model, a belt return line includes a first track 1 and a second track 2 arranged at intervals; and a plurality of slides 3 are slidingly provided on the first track 1 and the second track 2; and a driving module for driving the slide 3 to move is provided on one side of the first track 1 and the second track 2; and a first return module 4 and a second return module 5 are respectively provided on both sides, so that the slide 3 circulates in the first track 1, the first return module 4, the second track 2, and the second return module 5.

[0024] Specifically, the first track 1 and the second track 2 are arranged at intervals from each other to provide a movement path for the slide 3; the slide 3 slides on the first track 1 and the second track 2 to carry objects or components; the driving module is located on both sides of the first track 1 and the second track 2, providing driving force to push the slide 3 to move on the track, ensuring that the slide 3 can move according to a predetermined path and speed; the first reflow module 4 and the second reflow module 5 are respectively located on both sides of the system, guiding or circulating the slide 3 back to the starting position of the track, thereby realizing the circular motion of the slide 3 and ensuring the continuous operation of the system.

[0025] Furthermore, the first reflow module 4 includes a reflow bracket 6; and a linear module 7 is horizontally provided on the reflow bracket 6; and the linear module 7 is provided with a shifting seat 8 that slides back and forth synchronously with it; and the shifting seat 8 is provided with a third track 9 corresponding to the width of the first track 1 and the second track 2; and the slide 3 circulates between the first track 1 and the second track 2 through the reciprocating sliding of the shifting seat 8; the second reflow module 5 has the same structure as the first reflow module 4.

[0026] Specifically, the reflow bracket 6 provides a support structure for the reflow module to ensure stable operation of the system; the linear module 7 is horizontally installed on the reflow bracket 6, and is usually controlled by an electric drive system. Its function is to provide linear motion and drive the displacement seat 8 to move back and forth along the linear direction; the displacement seat 8 is connected to the linear module 7 and can move with the reciprocating motion of the linear module 7; the displacement seat 8 is an important connecting component between the slide 3 and the reflow track, which ensures that the slide 3 can circulate back and forth between the first track 1 and the second track 2; a third track 9 corresponding to the width of the first track 1 and the second track 2 is installed on the displacement seat 8, and the slide 3 moves between the first track 1 and the second track 2 along this third track 9 through the reciprocating sliding of the displacement seat 8; it ensures that the slide 3 can smoothly switch from one track to another to realize the reflow cycle; the design of the second reflow module 5 is exactly the same as the first reflow module 4, and the working principle and structure are highly consistent; the linear module 7 can adopt an existing commercially available linear module, which is not repeated here.

[0027] Furthermore, the driving module includes a plurality of belt positioning grooves 10 spaced apart on one side of the first track 1 or the second track 2, and a plurality of belt rollers 11 spaced apart; and a driving belt 12 is provided which is wound around the belt positioning grooves 10 and the belt rollers 11; the slide 3 contacts the driving belt 12 by its own gravity, so that the driving belt 12 drives the slide 3 to move synchronously.

[0028] Specifically, a belt positioning groove 10 is provided on one side of the first track 1 or the second track 2 to position and guide the belt. The position and spacing of the groove ensure that the belt always remains on the correct track, thereby preventing the belt from deviating or misaligning. Belt rollers 11 are provided at intervals to support and guide the movement of the drive belt 12. The provision of the belt rollers 11 can help reduce friction between the belt and other components, reduce energy loss, and ensure smooth belt movement. The drive belt 12 passes around the belt positioning groove 10 and the belt rollers 11 to form a complete circulation system. The drive belt 12 is a key component for power transmission and drives the slide 3 along the track by contacting the slide 3. The slide 3 contacts the drive belt 12 by its own gravity. The slide 3 has a certain downward force on the track, and through this gravity, the slide 3 can smoothly contact the belt and move synchronously. This not only avoids the need for an additional electric drive device, but also reduces the complexity and energy consumption of the system. The belt drive enables the slide 3 to move synchronously and circulate along the first track 1 and the second track 2, ensuring the efficient operation of the system and enabling the slide 3 to move precisely along the predetermined route and speed.

[0029] Furthermore, rubber gaskets 13 are provided on both sides of the bottom of the slide 3 ; and the rubber gaskets 13 are in contact with the driving belt 12 by their own gravity, so that the driving belt 12 drives the slide 3 to move synchronously.

[0030] Specifically, the rubber gaskets 13 on both sides of the bottom of the slide 3 can provide better contact force and friction, so that the slide 3 can stably contact with the driving belt 12; the softness of the rubber material itself can effectively increase the gripping force with the belt, ensuring that the belt can better drive the slide 3 to move; the rubber gasket 13 relies on the gravity of the slide 3 to contact the belt, which can reduce the demand for external power; through the friction between its own weight and the belt, the slide 3 can smoothly follow the movement of the belt and complete synchronous movement; the use of rubber gaskets 13 not only improves the driving efficiency, but also effectively reduces the wear between the bottom of the slide 3 and the track, thereby extending the service life of the equipment; rubber has It has certain elasticity and wear resistance, so that the friction force is uniform and stable during the movement of the slide 3; the rubber gasket 13 can also play a certain shock-absorbing role when the slide 3 contacts the belt, reducing the impact caused by unbalanced movement or external impact, and improving the smoothness of movement; the addition of the rubber gasket 13 enhances the contact force between the belt and the slide 3, thereby improving the driving efficiency; the belt can drive the slide 3 to move more stably with lower power consumption, reducing energy consumption and friction loss; because rubber has a certain softness, it can adapt to load changes in different working environments, ensuring that the slide 3 can reliably follow the belt to move synchronously under various working conditions.

[0031] Furthermore, a number of driving cylinders 14 are arranged at intervals on one side of the belt positioning groove; and the piston rods of the driving cylinders 14 are connected to positioning blocks 15; and the sides of the slide 3 are provided with positioning columns 16 corresponding to the positioning blocks 15; the driving cylinders 14 drive the positioning blocks 15 to engage with the positioning columns 16, thereby causing the slide 3 to break away from contact with the driving belt 12.

[0032] Specifically, the cylinder acts as a driving device, which can quickly respond to control signals and accurately push the positioning block 15; the pneumatic method can provide fast and smooth movement, ensuring that the slide 3 can be quickly separated from the drive belt 12 when needed; a positioning block 15 is connected to the piston rod of each driving cylinder 14, and the positioning block 15 corresponds to the positioning post 16 on the side of the slide 3; through the action of the driving cylinder 14, the positioning block 15 can accurately engage with the positioning post 16, thereby fixing the position of the slide 3 and causing it to be out of contact with the drive belt 12; when the driving cylinder 14 pushes the positioning block 15 to engage with the positioning post 16, the slide 3 is out of contact with the belt, so that the slide 3 no longer relies on the traction force of the drive belt 12, but can stay at the specified position alone; by controlling the engagement of the positioning block 15 with the positioning post 16 through the cylinder, the system can flexibly control the movement state of the slide 3 as needed; for example, in some process steps, it may be necessary to pause the movement of the slide 3 or temporarily isolate it from the belt drive in order to perform other operations.

[0033] Furthermore, a plurality of mounting brackets 17 are provided at intervals on one side of the first track 1 and the second track 2; and a slot-type photoelectric sensor 18 is provided on the mounting bracket 17; and a detection rod 19 is protruding from the side of the slide 3 close to the mounting bracket 17; when the detection rod 19 passes through the slot-type photoelectric sensor 18, the photoelectric sensor detects a passing signal and feeds the signal back to the control terminal.

[0034] Specifically, photoelectric sensors usually detect the presence of objects by emitting and receiving light beams; when the detection rod 19 on the slide 3 passes through the slot-type photoelectric sensor 18, the sensor will detect the change in the signal and then confirm the position and movement status of the slide 3; the accuracy and response speed of the sensor enable the system to sense the passage of the slide 3 in real time and provide accurate feedback; when the detection rod 19 passes through the photoelectric sensor, the sensor will immediately send a signal to the control terminal; this signal feedback can be used to trigger or adjust the next operation, such as starting / stopping the movement of the slide 3, or adjusting the status of other control modules; a protruding detection rod 19 is designed on the side of the slide 3 close to the mounting bracket 17, which is specifically used to trigger the photoelectric sensor; it ensures that the position of the slide 3 can be accurately monitored, and when the slide 3 moves, the detection rod 19 will directly pass through the sensing range of the sensor, thereby triggering the sensor signal.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
