In this embodiment, a feeding inclined surface 1313 is provided at the bottom of the jig bearing platform 131, and the feeding inclined surfaces 1313 of the two jig bearing platforms 131 are arranged in an eight-shaped shape.

[0036] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, a loading door 11 is provided below the bearing assembly 13, and one side of the loading door 11 is connected to the second cylinder 12. When loading, first load the product onto the product jig, such as loading the core pack of the aluminum electrolytic capacitor onto the fixture 7; then, the second cylinder 12 is started to open the loading door 11; then, the fixture 7 is pushed into the jig bearing platform 131 from the bottom of the jig bearing platform 131 through a cylinder (not shown in the figure) or other mechanism. Since the jig bearing platform 131 is connected to the connecting frame 93 through a rotating shaft 1312, the jig bearing platform 131 can rotate within a certain range, so that the two ends of the jig 7 can be squeezed into the jig bearing platform 131. Under the action of the reset spring (not shown in the figure) between the external plate 1311 and the connecting plate 91, the jig bearing platform 131 that is squeezed open is reset, so that the jig is placed on the step of the jig bearing platform 131.

[0037] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the product fixture is a fixture 7 for the core package of an aluminum electrolytic capacitor, including two connection panels 71 and a top plate 72; the top plate 72 is provided with connection holes 73 for inserting the anode lead and cathode lead on the core package; the two connection panels 71 are arranged opposite to each other, and a magnetic column 74 or a magnetic strip is arranged on the inner side of one panel; after the anode lead and the cathode lead are inserted into the fixture 7, the anode lead and the cathode lead are located on one side of the magnetic column 74 or the magnetic strip.

The isolation door assembly 6 includes a lifting rod 61 and an isolation door 62.

When the product jig loaded with the product is preheated in the preheating mechanism 1, the isolation door assembly 6 between the vacuum heating mechanism 2 and the preheating mechanism 1 is started, and the isolation door cylinder 63 opens the isolation door 62; then the first cylinder 14 is started, and the first push plate 15 pushes the product jig on the jig carrier 131 onto the support bar 212 in the vacuum heating mechanism 2, and the conveying chain group 211 lifts the support bar 212 loaded with the product jig by one station, so that the support bar 212 at the next station waits to be loaded with the product jig. As shown Fig.11 It is a structural schematic diagram of the isolation door assembly between the heat preservation mechanism and the vacuum heating mechanism.

[0039] In this embodiment, due to the provision of the isolation door 62 between the preheating mechanism 1 and the vacuum heating mechanism 2, the product fixture can be smoothly pushed from the preheating mechanism 1 to the supporting bar 212 of the vacuum heating mechanism 2. Figure 3 and Figure 4 As shown, a transition bearing platform 16 is provided between the jig bearing platform 131 and the bearing bar 212 .

[0040] In this embodiment, the product jigs loaded into the preheating mechanism 1 can be multiple products arranged in parallel to form a row or a single product. In order to improve efficiency, they are generally loaded in a row. When a row of product jigs in the preheating mechanism 1 is pushed into the vacuum heating mechanism 2 by the first push plate 15, the first cylinder 14 retracts the first push plate 15, and then the isolation door cylinder 63 closes the isolation door 62. A new product jig is loaded into the preheating mechanism 1, and after preheating is completed, it is pushed into the vacuum heating mechanism 2 by the first push plate 15. New product jigs containing products are continuously loaded into the preheating mechanism 1 to complete preheating, and are pushed into the vacuum heating mechanism 2 until product jigs are placed on the supporting strips 212 in the vacuum heating mechanism 2. The vacuum fan 8 and the heater 10 in the vacuum heating mechanism 2 are started until the drying of the product is completed. In this embodiment, the drying of the aluminum electrolytic capacitor core pack is specifically completed.

[0041] In this embodiment, the vacuum heating mechanism 2 and the heat preservation mechanism 3 are arranged side by side, separated by a partition, and the isolation door assembly 6 between the vacuum heating mechanism 2 and the heat preservation mechanism 3 is arranged on the upper part of the partition.

[0042] In this embodiment, the vacuum heating mechanism 2 and the heat preservation mechanism 3 both include a conveying assembly 21, such as Fig. 9 and Fig.10As shown, the conveying assembly 21 includes a conveying chain group 211 and a bearing bar 212; a pair of conveying chain groups 211 are arranged opposite to each other and move synchronously; the conveying chain group 211 includes two conveying chains, and the gear group connecting the two conveying chains is connected to a rotating shaft; the two ends of the bearing bar 212 are respectively connected to the two conveying chains of the same conveying chain group 211, and the bearing bar 212 is provided with a bearing step 2121 for the product fixture; the chain is driven by a motor.

The second push plate is not shown in the figure, and the connection structure between the second push plate and the third cylinder is the same as the connection structure between the first push plate and the first cylinder.

[0044] In this embodiment, after the heating of the product in the vacuum heating mechanism 2 is completed, the heater 10 in the heat preservation mechanism 3 is turned on; the isolation door 62 between the vacuum heating mechanism 2 and the heat preservation mechanism 3 is opened, and then the second push plate, driven by the third cylinder, pushes the product jig on the support bar 212 in the vacuum heating mechanism 2 onto the support bar 212 in the heat preservation mechanism 3. After the product jig on the support bar 212 in the vacuum heating mechanism 2 is pushed onto the support bar 212 in the heat preservation mechanism 3 in turn, the isolation door 62 between the vacuum heating mechanism 2 and the heat preservation mechanism 3 is closed.

[0045] In this embodiment, due to the setting of the isolation door 62 between the vacuum heating mechanism 2 and the insulation, in order to enable the product jig to be smoothly pushed from the supporting bar 212 of the vacuum heating mechanism 2 to the supporting bar 212 between the insulation, a transition supporting platform 16 is also provided between the supporting bar 212 of the vacuum heating mechanism 2 and the supporting bar 212 between the insulation.

[0046] In this embodiment, if Fig.12 and Fig.13 As shown, the unloading door 4 is arranged at the bottom of the heat preservation mechanism 3, the unloading mechanism 5 is arranged below the unloading door 4, and the unloading door 4 is connected to the fourth cylinder 41. The unloading mechanism 5 includes a receiving frame 51 and a discharging chain group 52; the discharging chain group 52 includes two discharging chains arranged opposite to each other, the receiving frame 51 is arranged between the two discharging chains, and is located directly below the conveying assembly 21 of the heat preservation mechanism 3.

The two material receiving plates 512 are located on both sides of the bottom plate 511 . The bottom plate 511 is connected to the material receiving cylinder 53 .

[0048] In this embodiment, when the product jig in the insulation mechanism 3 is being discharged, the fourth cylinder 41 first opens the unloading door 4, and then the receiving cylinder 53 is started to extend the receiving rack 51 to the bottom end of the conveying chain group 211 in the insulation mechanism 3; as the chain rotates, the two relatively arranged supporting bars 212 are separated, and the product jigs on the two relatively arranged supporting bars 212 are placed on the receiving rack 51 under the action of gravity, and then the receiving cylinder 53 retracts, so that the product jig on the receiving rack 51 is placed on the discharge chain group 52, and the product jig is taken out under the drive of the chain.

[0049] In this embodiment, the preheating mechanism 1, the vacuum heating mechanism 2, and the heat preservation mechanism 3 are all arranged in a glass cover; the glass cover of the preheating mechanism 1 opens at the position of the loading door 11 and the isolation door 62, the glass cover of the vacuum heating mechanism 2 opens at the position of the isolation door 62, and the glass cover of the heat preservation mechanism 3 opens at the position of the isolation door 62 and the unloading door 4.

[0050] Since the jig carrying platform 131 and the carrying bar 212 in this embodiment can accommodate many product jigs, the vacuum heating equipment in this embodiment has high production efficiency and does not require manual intervention throughout the process, and is suitable for automated production.
