[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1 to 9The present invention provides a conveyor line device, comprising: a main conveyor line mechanism 1, the main conveyor line mechanism 1 including a conveyor chain body 2 extending along a predetermined direction; and an acceleration line mechanism, the acceleration line mechanism including an acceleration belt body 6, the acceleration belt body 6 being arranged in parallel with the conveyor chain body 2; wherein, the conveying surface of the acceleration belt body 6 is higher than the conveying surface height of the conveyor chain body 2, so that after the workpiece 4 located on the conveyor chain body 2 moves to the position of the acceleration line mechanism, the workpiece 4 is transmitted to the acceleration line mechanism and driven by the acceleration line mechanism.

[0030] The conveyor line equipment provided by this invention includes a main conveyor line mechanism 1 and an acceleration line mechanism. The main conveyor line mechanism 1 includes a conveyor chain body 2 extending in a predetermined direction; preferably, the conveyor chain body 2 is a double-speed chain body. The acceleration line mechanism includes an acceleration belt body 6, which is arranged parallel to the conveyor chain body 2; preferably, the acceleration belt body 6 is a belt; wherein, the conveying surface of the acceleration belt body 6 is higher than the conveying surface of the conveyor chain body 2, preferably, the conveying surface of the acceleration belt body 6 is 1mm-2mm higher than the conveying surface of the conveyor chain body 2; so that after the workpiece 4 located on the conveyor chain body 2 moves to the position of the acceleration line mechanism, the workpiece 4 is transmitted to the acceleration line mechanism and driven by the acceleration line mechanism, thereby realizing the rapid transport of the workpiece 4 on the conveyor line equipment. It can be seen that the conveyor line equipment of this invention, by setting the main conveyor line mechanism 1 and the acceleration line mechanism, facilitates the rapid transport of the workpiece 4 on the conveyor line equipment, thereby solving the problem of low efficiency of the conveyor line equipment used for processing heat exchangers in the prior art.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the main conveyor line mechanism 1 has an inlet area and an outlet area. The inlet area and the outlet area of ​​the main conveyor line mechanism 1 are used to transport the workpiece 4 to or from the workstation 3 for processing the workpiece 4.

[0032] Specifically, there are two acceleration line mechanisms: the inbound acceleration line mechanism 7 and the outbound acceleration line mechanism 11. The inbound acceleration line mechanism 7 is located in the inbound area of ​​the main conveyor line mechanism 1, and the outbound acceleration line mechanism 11 is located in the outbound area of ​​the main conveyor line mechanism 1.

[0033] In the specific implementation process, such as Figure 1As shown, the conveyor line equipment also includes a tooling plate 5, on which the workpiece 4 to be processed is loaded. The tooling plate 5 loaded with the workpiece 4 to be processed starts to be transported from the entry area of ​​the main conveyor line mechanism 1, that is, the tooling plate 5 loaded with the workpiece 4 to be processed is transported on the conveyor chain body 2. When the tooling plate 5 loaded with the workpiece 4 to be processed is transported to the position of the entry acceleration line mechanism 7, the tooling plate 5 loaded with the workpiece 4 to be processed is driven to the entry acceleration line mechanism 7 and transported by the entry acceleration line mechanism 7 (that is, the tooling plate 5 loaded with the workpiece 4 to be processed is separated from the conveyor chain body 2 and transported by the entry acceleration line mechanism 7), thereby accelerating the speed at which the tooling plate 5 loaded with the workpiece 4 to be processed enters the station, so that the tooling plate 5 loaded with the workpiece 4 to be processed can be quickly transported to the position of the workstation 3 where the workpiece 4 to be processed is located.

[0034] like Figure 1 and Figure 2 As shown, after the workpiece 4 is processed at workstation 3, the tooling plate 5 carrying the processed workpiece 4 is transported by the outgoing acceleration mechanism 11, thereby accelerating the speed at which the tooling plate 5 carrying the processed workpiece 4 leaves the station, allowing it to quickly move away from the workstation 3. The accelerated transport by the inbound acceleration mechanism 7 and the outbound acceleration mechanism 11 improves the working efficiency of the conveyor equipment and optimizes the production cycle time.

[0035] The specific structure of the in-station acceleration line mechanism 7 in this embodiment is as follows: Figures 3 to 6 As shown, the entrance acceleration line mechanism 7 includes multiple entrance acceleration belts 701 and an entrance drive assembly. The multiple entrance acceleration belts 701 are arranged in parallel to form the acceleration belt line body 6 of the entrance acceleration line mechanism 7. The entrance drive assembly is driven to connect with the multiple entrance acceleration belts 701 to drive the multiple entrance acceleration belts 701 to move. Preferably, the entrance acceleration belts 701 are belts.

[0036] In this embodiment, as Figures 3 to 6 As shown, the entrance acceleration line mechanism 7 also includes multiple entrance main drive wheels 702, multiple entrance driven wheels 703, and multiple sets of support wheels 704. The multiple entrance main drive wheels 702 and multiple entrance driven wheels 703 are arranged in pairs corresponding to each other. Multiple entrance acceleration belts 701 are fitted onto the corresponding entrance main drive wheels 702 and entrance driven wheels 703. Multiple sets of support wheels 704 are arranged corresponding to the multiple entrance acceleration belts 701. Each set of support wheels 704 is supported on the inner side of the entrance acceleration belt 701, and each set of support wheels 704 is arranged at intervals along the extension direction of the corresponding entrance acceleration belt 701.

[0037] The entry drive assembly includes an entry drive motor 705, an entry reducer 706, an entry transition shaft 707, an entry coupling 708, and an entry pulley assembly 709. The entry drive motor 705 is connected to the entry reducer 706; the entry transition shaft 707 is connected to the entry reducer 706 via the entry coupling 708; and the entry pulley assembly 709 is connected to the entry transition shaft 707 and multiple entry acceleration belts 701 to drive the multiple entry acceleration belts 701 to move.

[0038] The entry pulley assembly 709 includes an entry pulley 710 and a first synchronous belt 711. The entry pulley 710 is connected to the entry transition shaft 707. The first synchronous belt 711 is fitted onto the corresponding entry pulley 710 and the entry main drive wheel shaft 712 to drive the entry main drive wheel 702 to rotate, thereby driving multiple entry acceleration belts 701 to move.

[0039] In the specific implementation process, such as Figures 3 to 6 As shown, the entrance acceleration line mechanism 7 further includes: an entrance main drive wheel shaft 712, connected to the entrance main drive wheel 702, for supporting the entrance main drive wheel 702 and rotating together with it to transmit motion; a support wheel shaft 713, connected to the support wheel 704, for supporting the support wheel 704; a first tensioning assembly 714, connected to the entrance driven wheel 703, for adjusting the distance between the entrance driven wheel 703 and the entrance main drive wheel 702; and an entrance driven wheel shaft 715, which, together with the entrance driven wheel 703, supports the entrance driven wheel 703 and rotates with it. The system includes a rotating mechanism to transmit motion; an inbound drive motor bracket 716, on which the inbound drive motor 705 is mounted; a first synchronous belt cover 717, which is mounted on the inbound pulley 710 and the first synchronous belt 711 to protect them from contamination; an inbound transition shaft support 718, on which the inbound transition shaft 707 is rotatably mounted to support it; and an inbound acceleration belt base plate 719, which connects the inbound acceleration line mechanism 7 to the main conveyor line mechanism 1.

[0040] In actual use, when the entry drive motor 705 starts, the entry drive motor 705 drives the entry reducer 706 to rotate, which drives the entry pulley 710 and the first synchronous belt 711 to rotate through the entry transition shaft 707 and the entry coupling 708. The first synchronous belt 711 is connected to the entry main drive wheel shaft 712, which drives the entry main drive wheel 702 to rotate through the entry main drive wheel shaft 712, thereby driving the entry acceleration belt 701 to start moving.

[0041] The specific structure of the exit acceleration line mechanism 11 in this embodiment is as follows: Figures 7 to 9 As shown, the departure acceleration line mechanism 11 includes a departure acceleration belt 1101 and a departure drive assembly. The departure acceleration belts 1101 are arranged in parallel to form the acceleration belt line body 6 of the departure acceleration line mechanism 11. The departure drive assembly is drivenly connected to the departure acceleration belt 1101 to drive the departure acceleration belt 1101 to move. Preferably, the departure acceleration belt 1101 is a belt.

[0042] The outbound drive assembly includes an outbound drive motor 1102, an outbound reducer 1103, an outbound transition shaft 1104, and an outbound coupling 1105. The outbound drive motor 1102 is connected to the outbound reducer 1103, and the outbound reducer 1103 is connected to the outbound transition shaft 1104 through the outbound coupling 1105.

[0043] In this embodiment, as Figures 7 to 9 As shown, the exit acceleration line mechanism 11 also includes an exit pulley assembly 1114, which is connected to the exit transition shaft 1104 and the exit acceleration belt 1101 respectively, so that the exit transition shaft 1104 drives the exit acceleration belt 1101 to move.

[0044] The outbound pulley assembly 1114 includes an outbound acceleration pulley 1106, an outbound drive pulley 1107, and an outbound driven pulley 1108. The outbound acceleration pulley 1106 and the outbound drive pulley 1107 are connected via an outbound pulley drive shaft 1122. The outbound drive pulley 1107 and the outbound driven pulley 1108 are arranged in pairs, and the outbound acceleration belt 1101 is fitted onto the corresponding outbound drive pulley 1107 and outbound driven pulley 1108. When the outbound acceleration pulley 1106 rotates, it drives the outbound drive pulley 1107 to rotate via the outbound pulley drive shaft 1122, thereby causing the outbound acceleration belt 1101 to start moving.

[0045] In this embodiment, as Figures 7 to 9 As shown, the exit acceleration line mechanism 11 also includes a lifting assembly, which includes a lifting component 1109. The lifting component 1109 has a lifting surface and is vertically and vertically arranged so that the lifting surface of the lifting component 1109 is higher or lower than the conveying surface of the acceleration belt line 6 of the exit acceleration line mechanism 11 by lifting the lifting component 1109.

[0046] In this embodiment, as Figures 7 to 9 As shown, the lifting assembly also includes a lifting drive component 1110 and a lifting connector 1111. The lifting drive component 1110 is driven to connect with the lifting component 1109 through the lifting connector 1111 to drive the lifting component 1109 to rise and fall.

[0047] In this embodiment, as Figures 7 to 9As shown, the lifting assembly also includes a lifting guide post 1112 and a lifting sleeve 1113. The lifting guide post 1112 is slidably installed in the lifting sleeve 1113, and the lifting guide post 1112 is connected to the lifting component 1109.

[0048] Preferably, the lifting component 1109 is a strip plate that extends along the conveying direction of the acceleration belt 6 of the exit acceleration line mechanism 11.

[0049] In this embodiment, as Figures 7 to 9 As shown, there are multiple lifting components, preferably two lifting components. Lifting components are provided on both sides of the acceleration belt 6 of the exit acceleration line mechanism 11, so that the tooling plate 5 is subjected to balanced force when it is lifted.

[0050] In the specific implementation process, such as Figures 7 to 9 As shown, the departure acceleration line mechanism 11 further includes: a lifting drive component base plate 1115, on which a lifting drive component 1110 is mounted for support; a synchronous pulley 1123, which is connected to the departure transition shaft 1104 and correspondingly mounted to the departure acceleration pulley 1106; a second synchronous belt 1116, on which the corresponding synchronous pulleys 1123 and 1106 are mounted; a departure transition shaft support 1117, on which the departure transition shaft 1104 is rotatably mounted to support the departure transition shaft 1104; and a second synchronous belt cover plate 1118, which is mounted on the synchronous pulleys 1123 and 1106. On the synchronous belt 1116, there are components to protect the synchronous pulley 1123 and the second synchronous belt 1116 from contamination; a second tensioning assembly 1119, which is connected to the exit driven pulley 1108 to adjust the distance between the exit driven pulley 1108 and the exit drive pulley 1107; an exit driven pulley shaft 1120, which is connected to the exit driven pulley 1108 and is used to support the exit driven pulley 1108; a connecting member 1121, which connects the exit acceleration line mechanism 11 and the main conveyor line mechanism 1; and an exit drive motor bracket 1124, on which the exit drive motor 1102 is mounted and used to support the exit drive motor 1102.

[0051] In actual use, the exit acceleration line mechanism 11 is installed at the location of workstation 3. When the tooling plate 5 loaded with the workpiece 4 is conveyed to the exit acceleration line mechanism 11, the lifting drive component 1110 extends to lift and drives the lifting guide column 1112 to lift the lifting component 1109, so that the tooling plate 5 loaded with the workpiece 4 is moved away from the exit acceleration belt 1101, so that the workpiece 4 can be processed.

[0052] When the workpiece 4 is finished, the lifting drive component 1110 retracts and drives the lifting guide column 1112 to lower the lifting component 1109 to the initial height. The tooling plate 5, which is loaded with the finished workpiece 4, returns to the exit acceleration belt 1101 and quickly exits the station.

[0053] The working principle of the exit acceleration mechanism 11 is as follows: When the exit drive motor 1102 starts, it drives the exit reducer 1103 to rotate, which drives the synchronous pulley 1123 to rotate through the exit transition shaft 1104 and the exit coupling 1105. This causes the second synchronous belt 1116 to rotate, which is connected to the exit acceleration pulley 1106, thereby driving the exit acceleration pulley 1106 to rotate. The exit acceleration pulley 1106 drives the exit drive pulley 1107 to rotate through the exit pulley drive shaft 1122, thereby causing the exit acceleration belt 1101 to start moving.

[0054] In this embodiment, as Figure 1 and Figure 2 As shown, the conveyor chain body 2 includes multiple parallel support tracks 12, and the acceleration line mechanism is arranged between two adjacent support tracks 12.

[0055] In this embodiment, as Figure 1 and Figure 2 As shown, the conveyor line equipment also includes a stopper 9. Along the conveying direction of the conveyor chain 2, the stopper 9 is disposed downstream of the acceleration line mechanism to limit the workpiece 4 to be processed. Preferably, at least a portion of the stopper 9 is movably disposed in the vertical direction to limit the workpiece 4 to be processed. Specifically, the stopper 9 is disposed in the inlet area and the outlet area.

[0056] In this embodiment, as Figure 1 and Figure 2 As shown, the conveyor line equipment also includes a sensor assembly 8, which is disposed between the inbound acceleration line mechanism 7 and the stopper 9, and is used to detect the position of the workpiece 4 to be processed. Preferably, the sensor assembly 8 is a diffuse reflection sensor assembly.

[0057] In this embodiment, as Figure 1 and Figure 2 As shown, the conveyor line equipment also includes a proximity switch 10, which is located on the side of the stopper 9 near the workstation 3 and is used to detect whether the workpiece to be processed is in place.

[0058] In actual use, the tooling plate 5 is loaded with the workpiece 4 to be processed. The tooling plate 5 loaded with the workpiece 4 to be processed starts to be transported from the entry area of ​​the main conveyor line mechanism 1, that is, the tooling plate 5 loaded with the workpiece 4 to be processed is transported on the conveyor chain body 2. When the tooling plate 5 loaded with the workpiece 4 to be processed is transported to the position of the entry acceleration line mechanism 7, the entry drive motor 705 of the entry acceleration line mechanism 7 starts, the entry acceleration line mechanism 7 starts to operate, and the tooling plate 5 loaded with the workpiece 4 to be processed is transmitted to the entry acceleration line mechanism 7 and then transported by the entry acceleration line mechanism 7 (that is, the tooling plate 5 loaded with the workpiece 4 to be processed is separated from the conveyor chain body 2 and transported by the entry acceleration line mechanism 7), thereby accelerating the speed of the tooling plate 5 loaded with the workpiece 4 to be processed, so that the tooling plate 5 loaded with the workpiece 4 to be processed can be quickly transported to the position of the workstation 3 where the workpiece 4 to be processed is located.

[0059] After the workpiece 4 is processed at workstation 3, the tooling plate 5 loaded with the processed workpiece 4 is transported by the exit acceleration line mechanism 11, thereby accelerating the exit speed of the tooling plate 5 loaded with the processed workpiece 4, so that the tooling plate 5 loaded with the processed workpiece 4 can quickly move away from the location of workstation 3 and complete the exit.

[0060] Meanwhile, when the tooling plate 5 carrying the workpiece 4 is conveyed to the workstation 3, the proximity switch 10 detects that the tooling plate 5 carrying the workpiece 4 is in place and sends a command to the stopper 9. Upon receiving the command, the stopper 9 begins to work, blocking the next tooling plate 5 carrying the workpiece 4 from advancing, so that the tooling plate 5 carrying the workpiece 4 is buffered on the inbound acceleration line mechanism 7. When the workstation 3 completes the processing of the workpiece 4 and moves away from the location of the workstation 3, the proximity switch 10 sends a stop command to the stopper 9, and the stopper 9 stops working, allowing the next workpiece 4 to enter the station quickly.

[0061] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0062] The conveyor line equipment provided by this invention includes a main conveyor line mechanism 1 and an acceleration line mechanism. The main conveyor line mechanism 1 includes a conveyor chain body 2 extending along a predetermined direction; preferably, the conveyor chain body 2 is a double-speed chain body. The acceleration line mechanism includes an acceleration belt body 6, which is arranged parallel to the conveyor chain body 2. The conveying surface of the acceleration belt body 6 is higher than the conveying surface of the conveyor chain body 2, so that after the workpiece 4 located on the conveyor chain body 2 moves to the position of the acceleration line mechanism, the workpiece 4 is transferred to the acceleration line mechanism and driven by it, thereby achieving rapid transport of the workpiece 4 on the conveyor line equipment. Therefore, the conveyor line equipment of this invention, by setting the main conveyor line mechanism 1 and the acceleration line mechanism, facilitates the rapid transport of the workpiece 4 on the conveyor line equipment, improving the working efficiency of the conveyor line equipment and solving the problem of low efficiency in existing conveyor line equipment used for processing heat exchangers.
