Description

Technical Field

[0001] The present invention relates to the field of automation technology, and in particular to a nickel-chromium wire pressing unit, a nickel-chromium wire pressing device and a nickel-chromium wire pressing method. Background Art

[0002] The nickel-chromium wire is a conductive metal wire, which is welded to a conductive welding point, and a conductive connection between the welding points can be achieved through the nickel-chromium wire.

[0003] Now it is necessary to weld the nickel-chromium wire and the gasket together to achieve conduction between the nickel-chromium wire and the gasket.

[0004] When welding the nickel-chromium wire, it is necessary to manually pull out the nickel-chromium wire, place it on the gasket, and directly weld the nickel-chromium wire and the gasket to form two welding points at the positions where the two ends of the nickel-chromium wire are connected to the gasket. The manual wire pulling method is inefficient and affects the production efficiency of the product. In addition, directly welding the nickel-chromium wire and the gasket is very inconvenient during the welding process because there is no connection between the nickel-chromium wire and the gasket, which further affects the production efficiency of the product. Summary of the invention

[0010] A further technical solution is that the material tray includes: two rows of the first positioning grooves, and a gap is left between the two rows of the first positioning grooves; the gasket is placed in one row of the first positioning grooves, and the pressure cover is placed above the other row of the first positioning grooves.

[0011] A further technical solution is that the height positions of the plurality of first mounting plates are different, and gradually increase from the pay-off end of the nickel-chromium wire to the take-up end of the nickel-chromium wire.

[0012] A nickel-chromium wire pressing device, characterized in that it includes: a pressing unit; a wire pay-off assembly connected to the frame for winding the nickel-chromium wire; a wire pulling assembly connected to the frame for pulling the nickel-chromium wire; a base connected to the frame; a transmission assembly connected to the frame and located above the base, and the material tray is placed on the transmission assembly; a loading assembly connected to the transmission assembly and close to the loading end of the transmission assembly; a unloading assembly connected to the transmission assembly and close to the unloading end of the transmission assembly; a receiving assembly connected to the base and located between the loading assembly and the unloading assembly.

[0013] Its further technical solution is that the loading assembly includes: a second gantry, connected to the transmission assembly; a loading cylinder, a cylinder seat connected to the second gantry; a loading plate, connected to the piston rod end of the loading cylinder, including: a loading plate body, both ends of the loading plate body are integrally formed with loading claws, the two loading claws are arranged opposite to each other, and at the same time extend toward the middle position close to the loading plate body; wherein, when the loading plate loads the material tray, the loading claws are located below the material tray.

[0014] Its further technical solution is that the unloading component includes: an unloading cylinder, a cylinder seat of which is connected to the transmission component; an unloading plate, connected to the end of the piston rod of the unloading cylinder, including: an unloading plate body, the end of the unloading plate body is integrally formed with an unloading claw; wherein, when the unloading plate unloads the material tray, the unloading claw is located below the material tray.

[0015] A further technical solution is that two blanking plates are provided, and the two blanking plates are arranged opposite to each other in the vertical direction.

[0016] A nickel-chromium wire pressing method comprises the following steps: S1, gasket loading: placing the gasket in the first positioning groove, and placing the material tray on the transmission component; S2, material tray loading: the transmission component transfers the material tray to the loading position, the loading cylinder is started, and the loading plate is driven to detach the material tray from the transmission component, and at the same time, the receiving component slides to the bottom of the loading plate, the loading cylinder is reset, and the loading plate places the material tray on the receiving component; S3, nickel-chromium wire pressing: the receiving component is reset, and at the same time, the wire pulling component pulls the nickel-chromium wire out of the wire releasing component so that the nickel-chromium wire is located directly above the gasket, and the first adapter plate moves , so that the corrugated suction cup absorbs the pressure cover, and after the pressure cover is absorbed above the nickel-chromium wire, the first adapter plate moves downward, and the pressure column presses the nickel-chromium wire to form the nickel-chromium wire and completes pre-fixation with the gasket; S4, tray unloading: the receiving assembly moves to transfer the tray to the unloading position, the unloading cylinder starts, drives the unloading plate to lift the tray from the receiving assembly, and then the unloading cylinder resets, and the unloading plate places the tray on the transmission assembly; S5, gasket unloading: after the gasket and the nickel-chromium wire are welded, the tray is transferred to the unloading end of the transmission assembly, and the welded gasket and the nickel-chromium wire are taken out from the tray as a whole.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0018] 1. High degree of automation: Before welding the nickel-chromium wire and the gasket, the nickel-chromium wire is first pressed to pre-fix the nickel-chromium wire and the gasket, which is convenient for subsequent welding of the nickel-chromium wire and the gasket and improves the welding efficiency. After welding, the nickel-chromium wire between adjacent gaskets can be cut, so that multiple gaskets form independent products;

[0019] When press-fitting the nickel-chromium wire, the operator places the gasket in the first positioning groove and places the material tray on the transmission component for automatic transmission; when the material tray moves to the loading position, the receiving component moves to the loading position to receive the material tray, and the loading component loads the material tray on the transmission component onto the receiving component; then, the receiving component moves to the initial position, the first adapter plate moves, driving the corrugated suction cup and the pressure column to move, the corrugated suction cup first adsorbs the pressure cover to separate the pressure cover from the material tray; then, the wire pulling component automatically pulls the nickel-chromium wire to the top of the gasket, so that the nickel-chromium wire is located between the gasket and the pressure cover; the first adapter plate moves, stacks the pressure cover above the gasket, and at the same time, the pressure column presses the nickel-chromium wire, causing the nickel-chromium wire to deform; then, the receiving component moves to the unloading position, and the automatic unloading component unloads the material tray on the receiving component onto the transmission component, completing the automatic unloading of the material tray;

[0020] 2. It is convenient for operators to take and place products: the gasket and the gland are placed in the first positioning grooves of two rows respectively. Before the nickel-chromium wire is pressed, when loading the gasket, the operator does not need to remove the gland from the tray, but can directly place the gasket in the first positioning groove of another row, which improves the loading efficiency of the gasket; after the nickel-chromium wire is pressed and welded with the gasket, when unloading the product, the operator does not need to remove the gland from the tray, but can directly take the product out of the tray, which improves the unloading efficiency of the product;

[0021] 3. High pressing efficiency: The pressing of nickel-chromium wires corresponding to multiple gaskets can be completed in a single operation without repeated operations, which greatly shortens the processing time and improves the pressing efficiency of nickel-chromium wires;

[0022] 4. Good press-fitting effect: Due to the material characteristics of the nickel-chromium wire itself, the nickel-chromium wire has deformability and a certain tension force. When the pressure column presses the nickel-chromium wire, the nickel-chromium wire is deformed; during press-fitting, the pressure column close to the nickel-chromium wire pay-off end contacts the nickel-chromium wire first, and the height positions of multiple pressure columns increase from the nickel-chromium wire pay-off end to the nickel-chromium wire take-up end in sequence, which can provide a certain deformation margin for the nickel-chromium wire during deformation, so that the forming effect of the nickel-chromium wire is better; avoid the possibility of the nickel-chromium wire breaking due to excessive press-fitting of the nickel-chromium wire by the pressure column close to the nickel-chromium wire pay-off end.

[0041] Example 1

[0042] Figure 1 The schematic diagram of the structure of the nickel-chromium wire pressing unit of the present invention is shown. Figure 2 A top view of the use of the gland compound material tray in the present invention is shown. Figure 3 The front view of the use of the gland and the material tray in the present invention is shown. Figure 1 As shown, in this embodiment 1, the directions of the three arrows in the coordinate system correspond to the X direction, the Y direction and the Z direction respectively, and the nickel-chromium wire pressing unit is used to press the nickel-chromium wire 4 and the gasket 2, so as to facilitate the welding of the nickel-chromium wire 4 and the gasket 2. Figure 1-3 The nickel-chromium wire pressing unit includes a frame 5, a material tray 1, a pressure cover 3 and a pressing assembly 13. Specifically, the material tray 1 is placed on the frame 5, and the gasket 2 and the pressure cover 3 are placed on the material tray 1. The pressing assembly 13 is connected to the frame 5 and is used to press the nickel-chromium wire 4 to deform the nickel-chromium wire 4 and realize the pre-fixation of the gasket 2 and the nickel-chromium wire 4.

[0043] Specifically, the material tray 1 is plate-shaped as a whole and parallel to the horizontal plane. The length direction of the material tray 1 is set along the X direction. The upper surface of the material tray 1 is provided with two rows of first positioning grooves 101 spaced along the width direction of the material tray 1.

[0044] The gasket 2 and the pressure cover 3 are respectively placed in the two rows of first positioning grooves 101. Before the nickel-chromium wire 4 is press-fitted, the operator does not need to remove the pressure cover 3 from the material tray 1 when loading the gasket 2. The gasket 2 can be directly placed in the other row of first positioning grooves 101, thereby improving the loading efficiency of the gasket 2. After the nickel-chromium wire 4 is press-fitted and welded with the gasket 2, when unloading the product, the operator does not need to remove the pressure cover 3 from the material tray 1. The product can be directly taken out of the material tray 1, thereby improving the unloading efficiency of the product.

[0045] Figure 4 The front view of the press-fit assembly structure of the present invention is shown. Figure 1 and Figure 4 Specifically, the press-fitting assembly 13 includes a first gantry 7, a first adapter plate 1301 and a first mounting plate 1302. The length direction of the first gantry 7 is consistent with the X direction, and is slidably connected to the frame 5. The first adapter plate 1301 is vertically arranged and parallel to the XOZ plane, and is located on one side of the first gantry 7. A second linear module 16 and a third linear module 17 are arranged between the first adapter plate 1301 and the first gantry 7. The length direction of the second linear module 16 is consistent with the X direction, and the second linear module 16 is fixedly connected to the first gantry 7. The length direction of the third linear module 17 is consistent with the Z direction, and the third linear module 17 is fixedly connected to the slider of the second linear module 16. The first adapter plate 1301 is fixedly connected to the slider of the third linear module 17.

[0046] In this embodiment 1, a plurality of first mounting plates 1302 are provided, and the number of first mounting plates 1302 corresponds to the number of each row of first positioning grooves 101. The first mounting plate 1302 includes a first portion and a second portion. The first portion is vertically arranged and is attached to the side wall of the first adapter plate 1301 away from the third linear module 17. The second portion is connected to the lower end of the first portion and extends in a horizontal direction away from the first adapter plate 1301. The second portion is integrally formed with the first portion, and the first mounting plate 1302 is L-shaped as a whole.

[0047] In this embodiment 1, the press-fitting assembly 13 also includes a corrugated suction cup 1303 and a pressure column 1304. Specifically, two corrugated suction cups 1303 and a pressure column 1304 are provided on each first adapter plate 1301. The corrugated suction cup 1303 and the pressure column 1304 are both fixedly connected to the second part. The pressure column 1304 and the two corrugated suction cups 1303 are arranged at intervals along the length direction of the second part, and the pressure column 1304 is located between the two corrugated suction cups 1303. The air inlet end of the corrugated suction cup 1303 is located above the second part and is connected to the external air source, and the adsorption end of the corrugated suction cup 1303 is located below the second part, for adsorbing the pressure cover 3.

[0048] Figure 5 FIG. 2 shows a top view of the press-fit assembly structure of the present invention. Figure 5 The upper surface of the second part is fixedly connected with the first mounting block 18. A connecting column 20 and a spring 21 are arranged between the pressure column 1304 and the first mounting block 18. The connecting column 20 is arranged vertically, the connecting column 20 is connected to the first mounting block 18, the spring 21 is connected to the connecting column 20, and the pressure column 1304 is connected to the spring 21.

[0049] In this embodiment 1, the connecting column 20 is fixed to the first mounting block 18 by the following structure. Specifically, a first plug hole 1801 corresponding to the pressure column 1304 is provided at the center of the first mounting block 18, and the first end of the connecting column 20 is plugged into the first plug hole 1801. A deformation groove 1802 is provided on the first mounting block 18, and the first end of the deformation groove 1802 is connected to the first plug hole 1801, and the second end of the deformation groove 1802 is connected to the outside. A locking member is connected to the first mounting block 18, and the locking member can be a bolt. The locking member passes through the deformation groove 1802, and the deformation groove 1802 is deformed by rotating the locking member, thereby clamping and fixing the connecting column 20. The spring 21 is coaxially arranged with the connecting column 20 and is located below the connecting column 20. The first end of the spring 21 is fixed to the second end of the connecting column 20. The upper end of the pressing column 1304 is fixed to the second end of the spring 21. The lower end of the pressing column 1304 is used to contact the nickel-chromium wire 4. When the pressing column 1304 presses the nickel-chromium wire 4, the spring 21 is compressed and deformed, providing a buffer force for the press-fitting of the nickel-chromium wire 4. At the same time, when the pressing column 1304 presses the nickel-chromium wire 4, it can be ensured that the lower end of the pressing column 1304 always presses against the nickel-chromium wire 4, further improving the press-fitting effect of the nickel-chromium wire 4.

[0050] Figure 6 Shows Figure 5 Sectional view along the AA axis. Figure 5 and Figure 6Furthermore, the press-fit assembly 13 also includes a second mounting block 19, which is connected to the connecting column 20 and is arranged near the second end of the connecting column 20. A second plug hole 1901 is provided at the center of the second mounting block 19, and the second end of the connecting column 20 is fixed to the second plug hole 1901. The entire spring 21 and the upper end of the press column 1304 are both located in the second plug hole 1901. The second mounting block 19 and the second plug hole 1901 provide guidance and limit for the movement of the press column 1304, so that the press column 1304 is more stable during the movement.

[0051] Furthermore, the height positions of the multiple first mounting plates 1302 are different, and they are successively increased from the first pressure column 1304 that contacts the nickel-chromium wire 4 to the last pressure column 1304 that contacts the nickel-chromium wire 4. Due to the material characteristics of the nickel-chromium wire 4, the nickel-chromium wire 4 has deformability and a certain tension force. When the pressure column 1304 presses the nickel-chromium wire 4, the nickel-chromium wire 4 is deformed; when press-fitting, the height positions of the multiple pressure columns 1304 are successively increased, which can provide a certain deformation margin for the nickel-chromium wire 4 when it is deformed, so that the forming effect of the nickel-chromium wire 4 is better; and the possibility of the nickel-chromium wire 4 being broken due to the excessive press-fitting of the nickel-chromium wire 4 by the pressure column 1304 that first contacts the nickel-chromium wire 4 is avoided.

[0052] Reference Figure 3 and Figure 6 Further, a vertically arranged first positioning column 302 is fixedly connected to the upper surface of the gland 3, a second positioning groove 1902 corresponding to the first positioning column 302 is formed on the lower surface of the second mounting block 19, and the first positioning column 302 is inserted into the second positioning groove 1902. A vertically arranged second positioning column 303 is fixedly connected to the lower surface of the gland 3, a third positioning groove 102 corresponding to the second positioning column 303 is formed on the upper surface of the tray 1, and the second positioning column 303 is inserted into the third positioning groove 102.

[0053] Reference Figure 2 Furthermore, a center hole 301 is provided at the center of the gland 3. The lower end of the compression column 1304 passes through the center hole 301 and extends to the bottom of the gland 3.

[0054] The implementation principle of Example 1 of the present invention is as follows: the operator places the gasket 2 in one of the rows of first positioning grooves 101, and places the nickel-chromium wire 4 directly above the gasket 2. When the press-fitting assembly 13 presses the nickel-chromium wire 4, the second linear module 16 and the third linear module 17 drive the first adapter plate 1301 to move. The corrugated suction cup 1303 adsorbs the pressure cover 3 and adsorbs the pressure cover 3 directly above the gasket 2. Subsequently, the first adapter plate 1301 moves downward to press the pressure cover 3 onto the nickel-chromium wire 4. The first adapter plate 1301 continues to move downward, and the pressure column 1304 presses the nickel-chromium wire 4, causing the nickel-chromium wire 4 to deform, thereby achieving pre-fixation with the gasket 2.
