[0035] The specific implementation of the present utility model is introduced with reference to the accompanying drawings.

[0036] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of the coating machine's climbing and threading mechanism with both automatic and manual threading modes. The overall setting is inclined. When the coating machine threads the electrode, the electrode is pulled from the bottom to the top. The threading mode can be switched between manual threading and automatic threading.

[0037] refer to Figures 1 to 8A coating machine climbing belt threading mechanism with both automatic and manual threading modes includes a chain 1, a manual drive device 2, an automatic drive device 3, a mode switching device 4, and a vertical tensioning device 5. The chain 1 is arranged along the climbing frame 101 of the coating machine, and the manual drive device 2, the automatic drive device 3, and the mode switching device 4 are arranged at intervals on the climbing frame 101 and cooperate with the chain 1; the manual drive device 2 includes a drive sprocket 24 driven by a manually shaken handle 22, and the drive sprocket 24 is engaged with the chain 1 to drive the chain 1 and the chain 1 The threading rod 9 on the pole piece is used for manual threading operation; the automatic driving device 3 includes a driving sprocket 31 driven by the first reduction motor 33, and the mode switching device 4 is connected to the chain 1 and is arranged on one side of the automatic driving device 3. When the mode switching device 4 drives the chain 1 to engage with the driving sprocket 31, the driving sprocket 31 drives the chain 1 and the threading rod 9 on the chain 1 to perform automatic threading operation of the pole piece. When the mode switching device 4 drives the chain 1 to disengage from the driving sprocket 31, the chain 1 is controlled by the manual driving device 2 to perform manual threading operation of the pole piece.

[0038] The embodiment of the present application has a coating machine climbing and threading mechanism with both automatic and manual threading modes. Manual threading operations are performed through a manual drive device 2, and automatic threading operations are performed through an automatic drive device 3. The first reduction motor 33 drives the active sprocket 31 to pull the chain 1 and the threading rod 9 to thread the pole piece, thereby improving the pole piece threading efficiency of the coating machine in the climbing section. The mode switching device 4 is used to switch between the automatic threading mode and the manual threading mode, which can meet the pole piece threading requirements under different working conditions and improve the compatibility of the coating machine.

[0039] It should be further explained that in the climbing section, the electrode is moved obliquely upward along the climbing frame 101, which is used to lift the electrode from the first layer of the coater to the second layer. The electrode is also threaded upward from the bottom along the climbing frame 101. The chain 1 arranged on the climbing frame 101 is divided into an upward chain 11 and a downward chain 12. The path of the upward chain 11 is the path of the electrode threading. The downward chain 12 cooperates with the manual drive device 2 and the automatic drive device 3 to drive the chain 1 to operate.

[0040] In order to adjust the tension of the chain 1, in this embodiment, refer to Figure 2 、 Figure 3 and Figure 7, multiple vertical tensioning devices 5 are arranged at intervals on the climbing frame 101, the vertical tensioning device 5 includes a mounting seat 51, a first passive sprocket 52 and a spring 53. The mounting seat 51 is fixed to the climbing frame 101, and the first passive sprocket 52 is movably set on the slide rod 55 of the mounting seat 51 through a slide seat 54 and engages with the chain 1. The spring 53 is sleeved on the slide rod 55, and the spring 53 provides an elastic force acting on the slide seat 54. The first passive sprocket 52 pushes the chain 1 under the action of the spring 53 to adjust the tension of the chain 1.

[0041] It should be further explained that the entire climbing frame 101 is provided with four vertical tensioning devices 5 from bottom to top. The first vertical tensioning device 5 is arranged at the upward chain 11 between the first and second second rollers 6. The first vertical tensioning device 5 is used to eliminate the change in the tension of the chain 1 caused by the threading rod 9 sticking to the pole piece. The second, third and fourth vertical tensioning devices 5 are all connected to the downward chain 12. The second vertical tensioning device 5 is arranged close to the manual drive device 2 to eliminate the change in the tension of the chain 1 caused by the manual drive device 2 driving the chain 1 to operate. The third vertical tensioning device 5 is in the middle of the downward chain 12 to eliminate the change in tension caused by the weight of the downward chain 12 itself. The fourth vertical tensioning device 5 is arranged close to the automatic drive device 3 to eliminate the change in tension caused by the mode switching device 4 and the automatic drive device 3.

[0042] It can be understood that, with such a configuration, the first passive sprocket 52 is pushed by the elastic force of the spring 53. When the chain 1 is too loose, the spring 53 will push the first passive sprocket 52, thereby pushing the chain 1 to bend, lifting and tightening the chain 1. When the chain 1 is too tight, the chain 1 will retreat and press against the first passive sprocket 52. The first passive sprocket 52 compresses the spring 53 for a certain distance, thereby loosening the chain 1, ensuring that the tension of the chain 1 is appropriate, avoiding the situation where the power consumption of the first reduction motor 33 increases and the bearings wear due to the tension of the chain 1 being too tight, and avoiding the situation where the chain 1 jumps and derails due to the tension of the chain 1 being too loose, thereby ensuring that the chain 1 can stably drive the threading rod 9 to move during the threading process.

[0043] In order to adjust the elastic force of the spring 53, in this embodiment, refer to Figure 2 、 Figure 3 and Figure 7 The vertical tensioning device 5 also includes an adjusting block 56 and an adjusting bolt 57. The adjusting block 56 is set on the slide rod 55, and the adjusting bolt 57 is set on the mounting seat 51 and connected to the adjusting block 56. The two ends of the spring 53 respectively abut against the adjusting block 56 and the slide seat 54. The adjusting bolt 57 adjusts the distance between the adjusting block 56 and the slide seat 54 to adjust the elastic force of the spring 53.

[0044] It can be understood that, with such a configuration, by rotating the adjusting bolt 57, the distance between the adjusting block 56 and the slide 54 changes, thereby changing the compression amount of the spring 53, and then adjusting the elastic force of the spring 53. During the long-term use of the chain 1, as the chain links wear, the chain 1 will become loose. The elastic force of the spring 53 can be easily adjusted by adjusting the bolt 57, thereby adjusting the tension of the chain 1 to a suitable range, so that the elastic force of the spring 53 is balanced with the tension of the chain 1.

[0045] In order to drive the driving sprocket 31 and the chain 1 to rotate, in this embodiment, reference Figures 1 to 4 A first roller 32 is provided on the climbing frame 101, and a driving sprocket 31 is coaxially fixed on the end face of the first roller 32. The first roller 32 is connected to the first reduction motor 33 through a coupling, and the first reduction motor 33 drives the first roller 32 and the driving sprocket 31 to rotate.

[0046] It can be understood that with such an arrangement, the first roller 32 needs to hold up the electrode during the coating process and push the electrode upward in a rotating manner. The first roller 32 is connected to the first reduction motor 33 on the outside, and the driving sprocket 31 is coaxially fixed with the first roller 32. When the electrode is automatically threaded, the first reduction motor 33 can drive the first roller 32 and the driving sprocket 31 to rotate together, and drive the chain 1 to operate through the meshing relationship between the driving sprocket 31 and the chain 1.

[0047] In order to support the chain 1, in this embodiment, reference Figures 1 to 5 A plurality of second rollers 6 are arranged at intervals on the climbing frame 101 , and a second passive sprocket 62 is movably provided on the end surface of the second roller 6 through a bearing, and the second passive sprocket 62 is engaged with the chain 1 .

[0048] It can be understood that with such an arrangement, the electrode is lifted from the first layer to the second layer of the coating machine through the climbing section, and the flexible electrode is easy to droop downward. Similarly, the chain 1 set along the climbing frame 101 will also droop downward. The eight second rollers 6 set at intervals are used to support the walking electrode to prevent the electrode from drooping downward. The second passive sprocket 62 supports the chain 1 to prevent the chain 1 from drooping downward, so that the path of the chain 1 coincides with the walking path of the electrode, so that the electrode is threaded accurately.

[0049] In order to manually drive the chain 1 to rotate, in this embodiment, refer to Figure 1 and Figure 6 The manual drive device 2 includes a rotating rod 21, a handle 22, a seat bearing 23, and a driving sprocket 24; the rotating rod 21 is movably set on the climbing frame 101 through the seat bearing 23, the handle 22 is set on the rotating rod 21 and exposed on the outside of the climbing frame 101, and the driving sprocket 24 is set on the rotating rod 21 and engages with the chain 1.

[0050] It is understood that, in this arrangement, the handle 22 is held by the operator, who rotates the rotating rod 21 through the handle 22, which drives the drive sprocket 24 to rotate. The rotating rod 21 is ensured to rotate smoothly by the seat bearing 23, and the chain 1 is driven to rotate by the meshing relationship between the drive sprocket 24 and the chain 1, thereby realizing the manual threading operation. In particular, during the automatic threading operation, the chain 1 driven by the active sprocket 31 will drive the drive sprocket 24 and the rotating rod 21 to rotate. The handle 22 and the rotating rod 21 do not have a brake structure or a limit structure, so that the manual drive device 2 will not interfere with the automatic threading operation.

[0051] In order to quickly switch the pole piece threading mode, in this embodiment, refer to Figure 1 、 Figure 3 and Figure 8 The mode switching device 4 includes a cylinder 41 and a third driven sprocket 42. The driving end of the cylinder 41 is provided with a driving seat 43. The driving seat 43 is provided with a first mounting rod 44. The third driven sprocket 42 is movably provided at the end of the first mounting rod 44.

[0052] It can be understood that, with such a configuration, the third passive sprocket 42 is movably connected to the first mounting rod 44 through an internal bearing, and the cylinder 41 uses compressed air as power to quickly drive the drive seat 43 to move in a straight line. When the pole piece is to be automatically threaded, the third passive sprocket 42 on the drive seat 43 can quickly lift the chain 1 to the active sprocket 31, so that the active sprocket 31 engages with the chain 1. At the same time, the lifting function of the cylinder 41 can also be used to control the tension of the chain 1.

[0053] In order to better support the chain 1, in this embodiment, refer to Figures 1 to 3 A plurality of fourth driven sprockets 8 are arranged at intervals on the climbing frame 101 , and the fourth driven sprocket 8 is mounted on the climbing frame 101 through a second mounting rod 81 .

[0054] The second mounting rod 81 is fixed to the climbing frame 101 by the fixing block 82, and the second mounting rod 81 is perpendicular to the climbing frame 101, and the second mounting rod 81 is perpendicular to the first roller 32 and the second roller 6, so that the axes of the fourth driven sprocket 8 and the third driven sprocket 42, the second driven sprocket 62, the first driven sprocket 52, the driving sprocket 31 and the driving sprocket 24 are parallel to each other, ensuring the stable engagement of the chain 1 with each sprocket, so that the chain 1 can run stably during the pole piece threading process; wherein, two fourth driven sprockets 8 are provided at the upward chain 11 of the first roller 32, which lifts the upward chain 11 above the first roller 32, so that the driving sprocket 31 of the first roller 32 does not contact and engage with the upward chain 11, so that the driving sprocket 31 only cooperates with the downward chain 12, and the mode switching device 4 cooperates with the downward chain 12 to control the downward chain 12 to contact, engage or disengage with the driving sprocket 31.

[0055] It can be understood that, with such a configuration, the fourth driven sprocket 8 is movably connected to the second mounting rod 81 through an internal bearing, the fourth driven sprocket 8 rotates on the second mounting rod 81, and the fourth driven sprocket 8 engages with the chain 1. The path direction of the chain 1 is changed by the guidance of the fourth driven sprocket 8, thereby preventing the chain 1 from interfering with other structures of the coating machine.

[0056] In order to better arrange the manual drive device 2 and the mode switching device 4, in this embodiment, reference Figures 1 to 3 The climbing frame 101 includes an upper frame 102 and a lower frame 103. The upper frame 102 is located obliquely above the lower frame 103. The manual drive device 2 is arranged at one end of the lower frame 103 away from the upper frame 102, and the mode switching device 4 is arranged at one end of the upper frame 102 away from the lower frame 103.

[0057] It should be further explained that both the upper frame 102 and the lower frame 103 use fixing rods 105 to fix the two vertical plates 104 to form a frame body, and the frame body is fixed to the partition between the first and second layers of the coater through the columns 106. The columns 106 of the lower frame 103 are set upward, and the columns 106 of the upper frame 102 are set downward, so as to fix the climbing frame 101 and the coater together, avoid displacement between the climbing frame 101 and the coater, and ensure that the entire belt threading mechanism can operate stably.

[0058] It can be understood that, with such a setting, the function of the climbing section is to lift the electrode from the first layer to the second layer of the coater, and the climbing frame 101 is divided into an upper frame 102 and a lower frame 103, so as to facilitate the installation of the climbing frame 101 on the coater production line. The handle 22 of the manual drive device 2 needs to be manually operated by the operator. The manual drive device 2 is set on the lower frame 103, which can facilitate the operator to operate the handle 22 at a lower level, thereby facilitating manual threading operations; the mode switching device 4 and the first roller 32 are both set on the upper frame 102, staggered with the manual drive device 2, to avoid mutual influence between the two.

[0059] In order to install the belt rod 9 on the chain 1, in this embodiment, refer to Figure 1 , mounting planes 91 are provided at both ends of the belt threading rod 9, and the mounting plane 91 passes through mounting holes 92 with mounting bolts. The mounting plane 91 is fixedly connected to the L-shaped chain plate 13 of the chain 1 by bolts.

[0060] It can be understood that with such a configuration, the threading rod 9 is a polished rod as a whole with a smooth surface, ensuring that the pole piece can be flatly attached to the threading rod 9. The threading rod 9 and the chain 1 can be installed together through the mounting planes 91 at both ends of the threading rod 9. The mounting planes 91 and the L-shaped chain plate 13 can be aligned and then fixed by bolts. The threading rod 9 and the chain 1 are installed together through the L-shaped chain plate 13, which is convenient to install and reduces the connection structure to reduce the load on the chain 1, saving effort in manual threading operations and reducing the load on the first reduction motor 33.

[0061] It should be further explained that, in addition to the powered first roller 32 and second roller 6, the climbing frame 101 is also provided with a plurality of unpowered third rollers 7. There is no connection between the third roller 7 and the chain 1, and its function is to support the pole piece. The climbing frame 101 supports the pole piece through a first roller 32, eight second rollers 6 and eight third rollers 7 to prevent the pole piece from falling from the climbing frame 101. Among them, the first roller 32, eight second rollers 6 and eight third rollers 7 are all below the upward chain 11. When the chain 1 and the threading rod 9 drive the pole piece for threading, the threading rod 9 pulls the pole piece upward, and the pole piece is supported by the second roller 6, the third roller 7 and the first roller 32 in turn. The second roller 6 rotates under the drive of the second reduction motor 61, and the first roller 32 rotates under the drive of the first reduction motor 33, and the friction force is used to push the pole piece upward to help the pole piece move upward.

[0062] The working process of the embodiment of the present application is divided into automatic threading operation and manual threading operation. For automatic threading operation, before the threading of the climbing section begins, the head end of the pole piece is fixed on the threading rod 9 to prepare for threading. The mode switching device 4 is started, and the cylinder 41 drives the third passive sprocket 42 to push the chain 1, lifting the chain 1, and the chain 1 is engaged with the active sprocket 31. The first reduction motor 33 drives the first roller 32 and the active sprocket 31 to rotate, and the active sprocket 31 drives the chain 1 and the threading rod 9 to climb upward. The second roller 6 rotates under the drive of the second reduction motor 61, giving the pole piece an upward friction force. After the pole piece follows the threading rod 9 to move upward into position, the sensor on the upper side of the climbing frame 101 detects that the threading rod 9 is in place, and controls the first reduction motor 33 to stop rotating, completing the automatic threading operation of the pole piece in the climbing section.

[0063] For manual threading operations, the head end of the pole piece is fixed on the threading rod 9, and the operator manually rotates the handle 22. The handle 22 drives the rotating rod 21 and the drive sprocket 24 to rotate. The drive sprocket 24 drives the chain 1 and the threading rod 9 to climb together. The second roller 6 rotates under the drive of the second reduction motor 61, giving the pole piece an upward friction force. After the pole piece moves upward into position following the threading rod 9, the sensor on the upper side of the climbing frame 101 detects that the threading rod 9 is in place, the second reduction motor 61 stops rotating and prompts with an alarm sound, and the operator stops shaking the handle 22 to complete the manual threading operation of the pole piece in the climbing section.

[0064] The embodiment of the present application has both manual threading and automatic threading modes, and the modes are switched according to the coating production conditions of different electrodes. Manual threading requires the cooperation of two people, while automatic threading can be completed by one person, saving time and effort, and improving the electrode threading efficiency of the coating machine in the climbing section. By switching between the automatic threading and manual threading modes through the mode switching device 4, the electrode threading requirements under different working conditions can be met, and the compatibility of the coating machine can be improved.

[0065] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
