[0033] like Figure 3 and Figure 4 As shown, the clamping member 8 includes: a connecting plate 801, which is fixed to the bottom of the welding head II 706; a clamping plate 802, which is slidably connected to the lower part of the connecting plate 801 through a guide rod, and the clamping plate 802 is used to cooperate with the mounting block 701 to limit and clamp the high-temperature sensor 01; a spring 803, which is arranged between the connecting plate 801 and the clamping plate 802, and the driving rod 707 is driven to rotate by the servo motor I 708, so that when the welding head II 706 gradually approaches the welding head I 704, the clamping plate 802 will clamp the leading welding head II 706 on the high-temperature sensor 01 until the welding head II 706 is squeezed on the welding head I 704 behind the spring 803, and the wire 00 and the high-temperature sensor 01 therein are welded; the end faces of the mounting block 701 and the connecting plate 801 that clamp the high-temperature sensor 01 are both provided with buffer pads for auxiliary clamping, and the buffer pads can reduce the pressure of the mounting block 701 and the connecting plate 801 clamping the high-temperature sensor 01, thereby avoiding damage to the high-temperature sensor 01.

[0034] like Figure 3-Figure 5 As shown, the material picking part 9 includes: an electric push rod Ⅰ901, installed on the top of the mounting block 701; an electric suction cup 902, installed on the push rod end of the electric push rod Ⅰ901, and the electric suction cup 902 is used to adsorb the high-temperature sensor 01 clamped on the feeding fixture 501, and bring the welded high-temperature sensor 01 between the welding head Ⅰ704 and the welding head Ⅱ706 for welding.

[0035] like Figure 1 , Figure 8 and Fig. 9 As shown, a wire stripping and cutting mechanism 12 is provided on the mounting frame 3, and the wire stripping and cutting mechanism 12 includes: a mounting plate 121, fixedly mounted on the mounting frame 3; an electric push rod III 122, mounted on the mounting plate 121; a mounting box 123, fixedly connected to the push rod of the electric push rod III 122; and a pneumatic scissors 124, installed in the mounting box 123. The pneumatic scissors 124 are intermittently controlled by the electric push rod III 122 to strip and cut the wire 00 transported by the wire feeding module 4, thereby improving the assembly efficiency of the high temperature sensor 01.

[0036] When the equipment assembles the high-temperature sensor 01, the staff first places the wire 00 on the wire feeding module 4, and controls the wire feeding module 4 to transport the welding wire 00 downward and start production. The staff puts the high-temperature sensor 01 and the protective sleeve 02 on the transmission module Ⅰ5 and the transmission module Ⅱ6 respectively, and places them on the feeding fixture 501 and the sleeve 601. When the wire feeding module 4 drives the welding wire 00 to descend close to the welding mechanism 7, the wire feeding module 4 is first closed and the pneumatic scissors 124 are activated. The closing angle of the pneumatic scissors 124 is controlled by the program so that the pneumatic scissors 124 can cut the outer skin of the wire 00 without damaging the internal metal core of the wire 00. Then the electric push rod Ⅲ122 is activated, and the push rod of the electric push rod Ⅲ122 is extended and drives The installation box 123 moves downward, and the pneumatic scissors 124 moving downward will peel off the outer skin of the wire 00. After closing the electric push rod III 122, the wire feeding module 4 is enabled again until the wire feeding module 4 transports the stripped metal core of the wire 00 downward to the designated welding area between the welding head I 704 and the welding head II 706. The wire feeding module 4 is closed and the transmission module I 5 is started. The transmission module I 5 stops the high-temperature sensor 01 on the feeding fixture 501 when it is transported close to the welding mechanism 7 through program control, and then the electric push rod I 901 is enabled. The push rod of the electric push rod I 901 extends and pushes the electric suction cup 902 to extend between the feeding fixtures 501, and the electric suction cup 902 is energized and adsorbed on the high-temperature sensor 01.

The servo motor Ⅰ708 drives the drive rod 707 to rotate through the output shaft. The thread on the drive rod 707 will drive the welding head Ⅱ706 toward the direction of the welding head Ⅰ704. At this time, the welding head Ⅱ706 will drive the clamping plate 802 to approach the clamping surface of the mounting block 701 through the spring 803. Since the clamping plate 802 will be clamped on the high-temperature sensor 01 before the welding head Ⅱ706, the high-temperature sensor 01 can be stably It is fixedly clamped between the mounting block 701 and the clamping plate 802.

As the welding head I 704 and the welding head II 706 are clamped together, the welding work of the wire 00 and the high-temperature sensor 01 is completed. Finally, the electric suction cup 902 is powered off and no longer adsorbs the high-temperature sensor 01, and the servo motor I 708 reverses to expand the welding head I 704 and the welding head II 706 through the driving rod 707, and then the wire feeding module 4 is activated to allow the wire 00 welded with the high-temperature sensor 01 to be continuously transported downward for subsequent glue injection processing.

[0038] like Figure 1 and Fig.10 As shown, a heating wire 13 is provided on one side of the bracket of the transmission module II 6 near the injection mechanism 10. The heating wire 13 is symmetrically installed on the bracket of the transmission module II 6 in a curved shape, and the heating wire 13 is symmetrically distributed on both sides of the protective sleeve 02 near the injection frame 104. The heating wire 13 is used to accelerate the reaction of the epoxy resin and the curing agent injected into the protective sleeve 02, so that the high-temperature sensor 01 after the welding of the wire 00 can be quickly solidified in the protective sleeve 02, completing the efficient assembly of the high-temperature sensor for production; an inclined discharge rack 14 is fixedly connected to the base 1, and the discharge rack 14 is located on one side of the support frame 2 near the injection mechanism 10, and the support frame 2 is provided with a discharge slot adapted to the discharge rack 14, and the assembled high-temperature sensor 01 can be automatically exported from the device through the discharge rack 14 for batch collection by processing personnel.

[0039] When the wire 00 welded with the high temperature sensor 01 is transported downward, the transmission module Ⅱ6 is controlled by the program, so that the protection sleeve 02 on the transmission module Ⅱ6 is driven to move through the sleeve 601, and the protection sleeve 02 moves to the position aligned with the wire 00, so that the transmission module Ⅱ6 is closed, until the high temperature sensor 01 welded on the wire 00 is transported downward and extends into the bottom of the protection sleeve 02, first close the wire feeding module 4 and activate the electric push rod Ⅱ102, the push rod of the electric push rod Ⅱ102 extends and pushes the guide plate 103 and the injection frame 104 close to the wire 00 and aligns with the protection sleeve 02 below it, at this time, the injection needle tube 105 will be distributed Around the pipe opening of the protective sleeve 02, and the glue injection needle tube 105 is facing the bottom of the protective sleeve 02, the glue pump 106 is activated again to draw the epoxy resin mixed with the curing agent in the glue storage box 101 into the glue delivery tube 107, and the epoxy resin drawn into the glue delivery tube 107 will flow through the glue injection frame 104 and then flow into the protective sleeve 02 from multiple glue injection needle tubes 105. At this time, the servo motor II 111 is activated again, and the servo motor II 111 reciprocates through the output shaft to drive the gear 112 to mesh with the rack 113, so that the rack 113 can reciprocate and drive the glue injection frame 104 to rotate on the guide plate 103. At this time, the glue injection needle tube 105 of the glue injection frame 104 will rotate and evenly inject the epoxy resin The resin is injected into the protective sleeve 02 to ensure that the epoxy resin can completely wrap the high temperature sensor 01 and the wire 00 and fill the entire space in the protective sleeve 02.

Since the heating wire 13 is symmetrically distributed on both sides of the protective sleeve 02, it can effectively accelerate the chemical reaction of the epoxy resin and the curing agent, promote the curing process of the resin, and shorten the curing time while forming a denser structure. When the ring After the epoxy resin completely solidifies the high-temperature sensor 01 and the wire 00 in the protective sleeve 02, the heating wire 13 is turned off, and the pneumatic scissors 124 are activated to directly cut the wire 00 transported by the wire feeding module 4. At the same time, the transmission module Ⅱ6 will send forward a solidified protective sleeve 02, and the protective sleeve 02 will be exported to the discharge rack 14 by the transmission module Ⅱ6. Finally, the high-temperature sensor 01 that has been solidified and assembled in the protective sleeve 02 is output to the collection box prepared in advance by the processing personnel through the discharge rack 14, so as to realize automatic batch collection. Therefore, the mutual cooperation between the various mechanisms can be controlled by the program, and the integrated automatic assembly production of the high-temperature sensor 01 can be realized.
