Description

Technical Field

[0001] The utility model relates to the technical field of conveying lines, in particular to a return line. Background Art

[0002] The reflow line is a crucial component of automated production lines. It employs a closed, looped conveyor path, allowing products to automatically return to their starting point or proceed to the next workstation after completing processing at one workstation, thus achieving a continuous production flow. This design not only improves production line efficiency and capacity, but also reduces material handling and waiting time, optimizing production flow. It is particularly well-suited for production environments with multiple processes and inconsistent processing times. However, existing reflow lines are inconvenient for disassembly and assembly of carriers, reducing the flexibility of the production line. Utility Model Content

[0003] The purpose of the utility model is to provide a return line to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0005] A reflow line includes a processing table and a carrier. Pads are installed on both sides of the upper surface of the processing table. A base plate is installed on the upper surfaces of the two pads. Conveyor belts are installed on both sides of the outer surface of the base plate. A motor that cooperates with the conveyor belt drive is installed at the bottom of the base plate. Rodless cylinders are installed between the two conveyor belts and on both sides in the length direction of the two conveyor belts. Transfer slides are installed on the upper surface of the sliding seat on the rodless cylinder. Linear slides are installed on the side of the two conveyor belts that are close to each other, and the linear slides and the transfer slides are set at the same height so that they can be aligned and connected with each other. A slider is installed at the bottom of the carrier, and the slider matches the transfer slide and the linear slide. Card slots for synchronous transmission are evenly distributed on the outer surface of the conveyor belt, and a card strip that matches the card slots is provided at the bottom of the carrier.

[0006] It can be seen that the arrangement of the card strips and card slots enables the conveyor belt to drive the carrier to move. When the carrier moves from the linear slide to the transfer slide, the rodless cylinder can drive the carrier to transfer to the linear slide on the other side for reverse transportation, thereby achieving the purpose of reflux. In addition, the two ends of the linear slide are designed with an open structure, which facilitates the disassembly and assembly of the carrier. The appropriate number and specifications of carriers can be installed according to production needs, which improves the flexibility of the entire production line. The motor is set on the lower side of the base plate, and the transfer slide, linear slide and carrier are located on the upper side of the base plate. The overall structure is compact and saves space.

[0007] Furthermore, stop bars are installed at the ends of the two conveyor belts.

[0008] Furthermore, support rails are installed on both sides of the upper and lower side surfaces of the base plate, grooves are opened on the surfaces of the support rails, and the conveyor belts are arranged in the grooves.

[0009] Furthermore, the motor is a servo motor.

[0010] Furthermore, two sliders are provided at the bottom of the carrier, and the carrier and the sliders are connected by bolts.

[0011] Furthermore, a plurality of angle brackets for fastening are installed on the outer surface of the supporting guide rail along its length direction.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0013] The utility model uses the arrangement of the card strips and the card slots to enable the conveyor belt to drive the carrier to move. When the carrier moves from the linear slide rail to the transfer slide rail, the rodless cylinder can drive the carrier to be transferred to the linear slide rail on the other side for reverse transportation, thereby achieving the purpose of reflux. In addition, the two ends of the linear slide rail are designed with open structures, which facilitates the disassembly and assembly of the carrier. The appropriate number and different specifications of carriers can be installed according to production needs, thereby improving the flexibility of the entire production line.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection", and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct connection or an indirect connection through an intermediate medium. Here, "fixed" means that the two are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0021] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0022] like Figure 1-4 As shown, a reflow line includes a processing table 100 and a carrier 109. Pads 101 are installed on both sides of the upper surface of the processing table 100. A base plate 102 is installed on the upper surfaces of the two pads 101. Conveyor belts 103 are provided on both sides of the outer surface of the base plate 102. A motor 105 that cooperates with the conveyor belt 103 is provided at the bottom of the base plate 102. Rodless cylinders 106 are provided between the two conveyor belts 103 and on both sides of the length direction thereof. Transfer slides 107 are installed on the upper surface of the sliding seat of the rodless cylinder 106. Linear slides 108 are provided on the side of the two conveyor belts 103 that are close to each other, and the linear slides 108 and the transfer slides 107 are provided at the same height so that they can be aligned and connected with each other. A slider 104 is installed at the bottom of the carrier 109, and the slider 104 matches the transfer slide 107 and the linear slide 108. The outer surface of the conveyor belt 103 is evenly distributed with slots for synchronous transmission, and the bottom of the carrier 109 is provided with a card strip matching the slot.

[0023] When in use, the two motors 105 drive the two conveyor belts 103 to move in opposite directions. Since the bottom card strip of the carrier 109 (not shown in the figure) is stuck in the card groove of the outer surface of the conveyor belt 103 as a synchronous tooth, it can drive the carrier 109 to move on the linear slide 108. When the carrier 109 moves to the transfer slide 107, the conveyor belt 103 stops running. At this time, the rodless cylinder 106 can drive the transfer slide 107 to move to the end of the linear slide 108 on the other side to correspond to it. The card strip at the bottom of the carrier 109 is re-engaged in the card groove on the outer surface of the conveyor belt 103. At this time, the conveyor belt 103 moves, and then drives the carrier 109 to move in the opposite direction on the linear slide 108 on the other side, thereby achieving the purpose of reflux movement of the carrier 109. When the carrier 109 needs to be disassembled, it is only necessary to disassemble and assemble the carrier 109 on the transfer slide 107, so that the appropriate number and different specifications of carriers 109 can be installed according to production needs, thereby improving the flexibility of the entire production line.

[0024] Specifically, a baffle 200 is installed at the end of each of the two conveyor belts 103. When the carrier 109 is transported to the transfer slide 107, the baffle 200 can block it, thereby ensuring the accuracy of the position of the carrier 109 and allowing the card strip at its bottom to be accurately inserted into the card groove on the outer surface of the conveyor belt 103 on the other side.

[0025] Specifically, support rails 300 are installed on both sides of the upper and lower sides of the base plate 102. Grooves 301 are formed on the surface of the support rails 300, and the conveyor belt 103 is positioned within the grooves 301. The support rails 300 provide support for the conveyor belt 103, preventing the conveyor belt 103 from separating from the slots and strips due to elastic deformation during operation. This improves the stability and reliability of transmission.

[0026] Specifically, the motor 105 is a servo motor, which can accurately control the running speed and angle of the conveyor belt 103, thereby ensuring that the card strip can be accurately docked with the card slot. Preferably, the motor 105 is not limited to a servo motor, and can also be a stepper motor.

[0027] Specifically, two sliders 104 are provided at the bottom of the carrier 109, and the carrier 109 and the sliders 104 are connected by bolts. The setting of the two sliders 104 provides stable support for the carrier 109, making it more stable during movement, and the bolt connection method makes it convenient to replace it.

[0028] Specifically, the outer surface of the support rail 300 is installed with multiple corner codes 400 for fastening along its length direction. The multiple corner codes 400 provide good reinforcement for the support rail 300, ensuring the structural stability of the support rail 300, and further ensuring that the conveyor belt 103 can operate stably.

[0029] The present application is not limited to using the rodless cylinder 106 to drive the transfer slide 107 to move back and forth between the two linear slides 108 along the width direction of the substrate 102. The rodless cylinder 106 can also be replaced by a driving mechanism such as a rod cylinder, a linear electric cylinder or an electric ball screw slide.

[0030] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
