[0028] By setting up a placement component, it is possible to prevent the solder paste that has not reached the rewarming time from being taken and used; the placement component includes a mounting plate 3, a fixing frame 4, and a box body 5 with one side open. The mounting plate 3 is installed on the top of the support frame 2, the fixing frame 4 is fixedly connected to the top of the mounting plate 3, the box body 5 is fixedly connected to the top of the fixing frame 4, several placement holes 6 are opened on the top of the box body 5, and several observation holes 7 are opened on the top of the box body 5 at the rear side of the placement holes 6. A plurality of electric push rods 8 are installed at the front end of the top of the mounting plate 3. The push rods of the plurality of electric push rods 8 movably penetrate through the bottom of the box body 5. The push rod of the electric push rod 8 is fixedly connected with a push plate 9 inside the box body 5. A controller 10 is installed at the rear side of the electric push rod 8 on the top of the mounting plate 3. A start button 11 is installed on the front side of the cabinet body 1. The electrical output end of the start button 11 is electrically connected to the electrical input end of the controller 10. The electrical output end of the controller 10 is electrically connected to the electrical input end of the electric push rod 8; through the partition plate 18, multiple placed solder pastes can be separated. At this time, by pressing the start button 11, the start button 11 gives a start signal to the controller 10. At this time, the controller 10 starts timing. When the solder paste has been rewarmed for four hours, the controller 10 then controls the push rod of the electric push rod 8 to extend. The push rod of the electric push rod 8 drives the push plate 9 to move upward, so that the top end of the solder paste moves out of the inside of the box body 5 through the placement hole 6. At this time, the solder paste that has reached the rewarming time can be taken out of the inside of the box body 5.

[0029] By setting up a material taking component, it is convenient to take the mis-placed solder paste; the material taking component includes a connecting frame 13, a guiding column 14, and a top column 15. Several long through slots 12 are opened on the bottom side inside the box body 5. The connecting frame 13 is fixedly connected to the bottom of the box body 5. One end of the guiding column 14 movably penetrates through the sliding slot at the bottom of the connecting frame 13. The top column 15 is fixedly connected to one end of the guiding column 14. A telescopic spring 16 is movably sleeved on the outer side of the guiding column 14. The other end of the guiding column 14 is fixedly connected with a pulling block 17. Both ends of the top column 15 are respectively movably inserted into the inside of the long through slot 12. One end of the telescopic spring 16 is fixedly connected to the top of the pulling block 17, and the other end of the telescopic spring 16 is fixedly connected to the bottom of the connecting frame 13; by pushing the pulling block 17 upward to drive the guiding column 14 to move inside the connecting frame 13, the guiding column 14 is made to push both ends of the top column 15 to move out of the inside of the long through slot 12. At this time, both ends of the top column 15 move between two solder pastes. Pull the guiding column 14 on the pulling block 17 to move in the sliding slot, so as to drive the solder paste to move inside the box body 5 through the top column 15, and the solder paste can be moved out of the open end of the box body 5 to take the solder paste.

[0030] Inside the box body 5, a number of partition plates 18 are fixedly connected. Through the partition plates 18, multiple placed solder pastes can be separated. At the front side of the support frame 2 on the top of the cabinet body 1, a storage groove 19 is provided. The push plate 9 is located directly below the placement hole 6. The push plate 9 is located between the two partition plates 18. The push rod of the electric push rod 8 drives the push plate 9 to move upward, so that the top of the solder paste moves out of the inside of the box body 5 through the placement hole 6. At this time, the solder paste that has reached the rewarming time can be taken out of the inside of the box body 5.

[0031] Regarding the working principle or structural principle, when the solder paste needs to be rewarmed, the refrigerated solder paste is placed inside the box body 5. Through the partition plates 18, multiple placed solder pastes can be separated. At this time, by pressing the start button 11, the start button 11 gives a start signal to the controller 10. At this time, the controller 10 starts timing. When the solder paste has been rewarmed for four hours, the controller 10 then controls the push rod of the electric push rod 8 to extend. The push rod of the electric push rod 8 drives the push plate 9 to move upward, so that the top of the solder paste moves out of the inside of the box body 5 through the placement hole 6. At this time, the solder paste that has reached the rewarming time can be taken out of the inside of the box body 5. After the solder paste is taken out, by pressing the start button 11 again, the controller 10 controls the push rod of the electric push rod 8 to reset, so that the push plate 9 resets. Due to the inclined setting of the box body 5, the solder paste placed at the rear will move inside the box body 5, so that the solder paste at the rear moves above the push plate 9, which is convenient for taking the rewarmed solder paste.

[0032] When multiple solder pastes are misplaced between the two partition plates 18 and the extra solder paste needs to be taken out, by pushing the pull block 17 upward to move, the pull block 17 drives the guide post 14 to move inside the connecting frame 13, so that the guide post 14 pushes both ends of the top post 15 out of the inside of the long through groove 12. At this time, both ends of the top post 15 move between the two solder pastes. During this process, the telescopic spring 16 is in a compressed state. At this time, the guide post 14 on the pull block 17 can be pulled to move in the chute, so that the solder paste is driven to move inside the box body 5 through the top post 15, and the solder paste can be moved out of the open end of the box body 5, which is convenient for taking the solder paste.
