The translation feeding mechanism 30 is arranged on an adjacent pair of heating furnace bodies 10 and located adjacent to the feeding ports. It can extend from the side of the discharging feeding port 102 of one heating furnace body 10 to the side of the feeding feeding port 101 of the adjacent heating furnace body 10. Figure 8 As shown, the translation feeding mechanism 30 comprises a second driving part and a push piece 35 connected thereto. The push piece 35 drives the product to be fed from one heating cavity to another heating cavity.

[0032] In the utility model, the product can be fan-out panel level package (FOPLP) substrate which has similar sheet structure, in preferred one kind of embodiment, four heating units 100 are arranged, namely first heating unit 100a, second heating unit 100b, third heating unit 100c and fourth heating unit 100d in series, four heating units 100 are arranged in adjacent U shape, wherein, the feeding feeding port 101 on the heating furnace body 10 of first heating unit 100a is arranged at the lower part thereof, the discharging feeding port 102 is arranged at the upper part of the opposite side thereof, the feeding feeding port 101 on the heating furnace body 10 of second heating unit 100b is arranged at the upper part thereof and is communicated with the discharging feeding port 102 in first heating unit 100a, and the discharging feeding port 102 is arranged at the lower part of the side thereof, the feeding feeding port 101 on the heating furnace body 10 of third heating unit 100c is arranged at the lower part thereof and is communicated with the discharging feeding port 102 in second heating unit 100b, and the discharging feeding port 102 is arranged at the upper part of the side thereof, the feeding feeding port 101 on the heating furnace body 10 of fourth heating unit 100d is arranged at the upper part thereof and is communicated with the discharging feeding port 102 in third heating unit 100c, and the discharging feeding port 102 is arranged at the lower part of the opposite side thereof, the communication of four heating cavities is realized by the cooperation of the feeding feeding port 101 and the discharging feeding port 102, and the product is sequentially formed upward movement, downward movement, again upward movement, again downward movement in four heating cavities by the driving of vertical feeding mechanism 20 and translation feeding mechanism 30, four first bearing parts 22 and four second bearing parts 23 are preferably arranged in vertical feeding mechanism 20, each first bearing part 22 and each second bearing part 23 are arranged adjacently, and four groups of combinations are located at four corner positions in the heating cavity, which can realize the stable support of the product, wherein, the first rotating shaft 221 only drives the first support rod 222 on it to rotate in the horizontal plane, the second rotating shaft 231 can also drive the second support rod 232 to move vertically while driving the second support rod 232 to rotate in the horizontal plane, so that the support of the product and the movement in the vertical direction can be realized by the movement form and movement track of the first support rod 222 and the second support rod 232, for example, when the product is supported by the first bearing part 22, that is, the product is supported by four first support rods 222, because the first support rod 222 has a rotating trend, the contact between the first support rod 222 and the first support rod 222 will disappear at a certain position, so that the product is not supported by the first support rod 222, that is, the vertical projection of the product and four first support rods 222 does not coincide, but because the second support rod 232 in the second support part 23 also rotates, when the vertical projection of the product and four second support rods 232 has a coincidence position, the product can be supported, that is, the product is alternately supported by the first support rod 222 and the second support rod 232, and because the second support rod 232 moves up or down under the driving of the second rotating shaft 231,Therefore, the product can be lifted or lowered (the rotation of the first supporting rod 222 provides a space for lifting or lowering after the vertical projection of the product and the first supporting rod 222 are not coincident), and when the lifting or lowering distance is set, the contact between the product and the second supporting rod 232 disappears at a certain position, so that the product is not supported by the second supporting rod 232, but is supported by the first supporting rod 222 of the upper or lower layer which has a coincident position with the vertical projection of the product after rotation, thereby forming a multi-layer structure in which multiple products can be placed. The product moves up and down in the heating cavity through the support of the first supporting rod 222 and the second supporting rod 232 and the lifting or lowering. In combination with the arrangement form of the four heating units 100 in the embodiment, the specific movement process of the product is as follows: the product enters from the feeding feeding port 101 (located at the bottom) of the first heating unit 100a through the feeding line or the mechanical hand, is lifted to the upper part of the heating cavity of the first heating unit 100a by the first vertical material mechanism 200a, is pushed to the feeding feeding port 102 (located at the upper part) of the second heating unit 100b from the discharging feeding port 102 (located at the upper part) by the action of the push piece 35 in the horizontal feeding mechanism 30, is lowered to the lower part of the heating cavity of the second heating unit 100b by the second vertical material mechanism 200b, is pushed to the feeding feeding port 102 (located at the lower part) of the third heating unit 100c from the discharging feeding port 102 (located at the lower part) by the action of the push piece 35 in the horizontal feeding mechanism 30, is lifted to the upper part of the heating cavity of the third heating unit 100c by the third vertical material mechanism 200c, is pushed to the feeding feeding port 102 (located at the upper part) of the fourth heating unit 100d from the discharging feeding port 102 (located at the upper part) by the action of the push piece 35 in the horizontal feeding mechanism 30, is lowered to the lower part of the heating cavity of the fourth heating unit 100d by the fourth vertical material mechanism 200d, and is discharged from the discharging feeding port 102 (located at the lower part) by the action of the push piece 35 in the horizontal feeding mechanism 30. After the whole heating process is completed, the product can be discharged by the feeding line or the mechanical hand.

[0033] In the present invention, although the product is heated by multiple heating furnace bodies 10 (heating cavities), the vertical feeding mechanism 20 and the translation feeding mechanism 30 are used to achieve the connection between product lifting and translation. Compared with the conventional heating equipment that relies on horizontal feeding to heat, each heating furnace body in the present oven can realize the heating of the product during the vertical lifting process, thereby improving space utilization, and multiple heating units 100 are arranged in a bent shape, which can shorten the extension space of the equipment in the horizontal direction, thereby reducing the occupied space of the entire equipment; moreover, the vertical feeding mechanism 20 is used to lift and lower the heating furnace body 10, and more products can be placed in a flat form, thereby improving work efficiency; furthermore, the vertical feeding mechanism 20 realizes the transfer and lifting of the product through the rotating first support rod 222 and the rotating and lifting second support rod 232, without the need for the circulating flow of multiple support platforms, which can also save the occupied space of each heating furnace body.

[0034] Preferably, the temperature in the same heating cavity is the same, and the temperature in the four heating cavities increases first and then decreases along the order in which they are arranged, so that a complete heating process of heating and cooling can be achieved. In order to ensure the constant temperature in each heating cavity and avoid heat transfer to the adjacent heating cavity, a closed structure is provided on the side of the feeding port of the heating furnace body 10. Figure 2 As shown, the heating unit 100 should be the second heating unit 100b (based on the position of the heating unit 100 among the four heating units, and the setting positions of its feed port 101 and discharge port 102), which is provided with a first closing structure 41 at the feed port 101, and a second closing structure 42 at the discharge port 102. The first cylinder 411 in the first closing structure 41 drives the first sealing plate 412 to close or open the feed port 101, and the second cylinder 421 in the second closing structure 42 drives the second sealing plate 422 to close or open the discharge port 102; when the feed port is closed, the temperature in adjacent heating cavities cannot be transferred to each other, thereby ensuring the temperature stability in each heating cavity. When the feed port is opened, it is used to realize the transfer of products in adjacent heating cavities, and the product transfer is completed and then closed again to seal the feed port.

[0035] In the above embodiment, four heating units 100 are arranged adjacent to each other in a U-shape. Different arrangements can also be set according to different numbers of heating units 100. For example, in another embodiment, three or four heating units are arranged in an L-shape, five heating units are arranged in an L-shape or a U-shape, six heating units are arranged in an S-shape, etc., all of which can reduce the space occupied by the equipment by heating the product in a lifting state in the heating furnace body and arranging multiple heating units in a bent shape.

[0036] For the specific structure of the first driving part 21 in the vertical feeding mechanism 20, as shown in Figures 4 to 6 the first driving part 21 includes a driving unit 211, a first connecting rod assembly 212 and a second connecting rod assembly 213, the first connecting rod assembly 212 and the second connecting rod assembly 213 are connected with the first rotating shaft 221 and the second rotating shaft 231 respectively, the driving unit 211 includes a first motor 2111 and a driving wheel 2112 arranged at the output end of the first motor 2111, the driving wheel 2112 is provided with a guide groove 2112a which is connected in head and tail and has different heights on the circumferential wall, the first connecting rod assembly 212 and the second connecting rod assembly 213 are connected with the upper end of the driving wheel 2112 and are driven to swing, and part of the second connecting rod assembly 213 is embedded in the guide groove 2112a and is driven to lift. In order to realize the rotation of the first rotating shaft 221, when the driving wheel 2112 is driven to rotate by the first motor 2111, it drives the first connecting rod assembly 212 to swing, and the rotation of the first rotating shaft 221 is realized through the swing of the first connecting rod 212. Specifically, the first connecting rod assembly 212 includes a first frame 2121, a first pin shaft 2121a on the first frame 2121 is rotatably arranged in an annular guide groove 2112b on the upper end of the driving wheel 2112, and the lower end is translatably arranged on a first guide rail 2122 on the heating furnace body 10, a plurality of first waist holes 2121b on the plurality of ends of the first frame 2121 are respectively matched with a plurality of first rotating shafts 221, therefore, while the driving wheel 2112 rotates, the top end of the first frame 2121 (the first pin shaft 2121a) is driven to change position due to the annular guide groove 2112b, and the lower end of the first frame 2121 is limited to move only in one horizontal direction by the first guide rail 2122, so that the swing of the first frame 2121 is realized, and the rotation of the first rotating shaft 221 is realized by the four first waist holes 2121b on the four ends driving the first rotating shaft 221. It should be noted that the upper end of the first rotating shaft 221 is an eccentric structure, based on which the relative movement of the eccentric structure in the first waist hole 2121b and the movement of the eccentric structure relative to the heating furnace body 10 can be realized, so as to realize the rotation of the first rotating shaft 221 driven by the eccentric structure as a whole.

When the driving wheel 2112 rotates, the guide wheel 2132a embedded in the guide groove 2112a will lift with the change of the height of the guide groove 2112a, so that the vertical plate 2132 drives the top plate 2131 to lift (the upper end of the top plate 2131 is provided with a clearance hole 2130 to realize the mutual clearance of the top plate 2131 and the first motor 2111 during the lifting process). Since the upper end of the second rotating shaft 231 is connected with the lower end of the top plate 2131, the lifting action of the second rotating shaft 231 can be realized. Moreover, the second pin shaft 2133a on the second frame 2133 is rotatably arranged at a non-central position of the upper end of the driving wheel 2112, and the lower end is translatably arranged on the second guide rail 2134 on the heating furnace body 10. The second waist hole 2133b on the four ends of the second frame 2133 is respectively matched with the plurality of second rotating shafts 231. Therefore, when the driving wheel 2112 rotates, the top end of the second frame 2133 (the second pin shaft 2133a) at the non-central position drives the position change, and the lower end of the second frame 2133 is limited by the second guide rail 2134 to move only in one horizontal direction, so that the swing of the second frame 2133 is realized. The rotation of the second rotating shaft 231 is realized by the four second waist holes 2133b respectively arranged at the four ends driving the second rotating shaft 231. It should be noted that the upper end of the second rotating shaft 231 is also provided with an eccentric structure, so that the relative movement of the eccentric structure in the second waist hole 2133b and the movement relative to the heating furnace body 10 can be realized.
