Description

Technical Field

[0001] The utility model relates to the technical field of curing equipment manufacturing, and particularly relates to a curing furnace provided with an auxiliary blanking device. Background Art

[0002] A curing furnace is a common curing device used for high-temperature curing processing of products such as rigid circuit boards and flexible circuit boards. The vertical curing furnace is characterized by a small floor area but a relatively high height. The feeding port and the blanking port of the existing vertical curing furnace are both arranged at a low position. To ensure continuous production, two sets of "crawler-type" lifting mechanisms are arranged in the furnace cavity. After the product enters the furnace cavity from the feeding port of the vertical curing furnace, it is lifted to the top by the first set of lifting mechanisms, then translated to the second set of lifting mechanisms, and the second set of lifting mechanisms lowers the product to the height of the blanking port to take it out of the furnace cavity.

[0003] It should be noted that in order to be able to carry the product, the length of the lifting mechanism is obviously not shorter than the product, which means that the length of the vertical curing furnace with two sets of "crawler-type" lifting mechanisms in the furnace cavity will exceed twice the length of the product. Generally speaking, the size of common circuit boards is not too large, basically within 50 centimeters. Even for a vertical curing furnace with a conventional design, the length of its furnace cavity is not too large and can be accepted.

[0004] However, with the development of new energy vehicles, the demand for flexible circuit boards used in new energy vehicle battery packs is increasing day by day. The size of this flexible circuit board is relatively large (about two meters in length). If a vertical curing furnace with a conventional design is still used, the length of the furnace cavity of the vertical curing furnace will exceed four meters, and the volume is very large. The large furnace cavity makes it difficult to uniformly control the internal temperature. There are often large temperature differences in various regions of the furnace cavity, which is likely to cause uneven curing of the product and affect the product quality.

[0032] The present utility model will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 11 , a curing furnace with an auxiliary blanking device, comprising a vertical curing furnace 100 and an auxiliary blanking device 200, wherein the auxiliary blanking device 200 is arranged outside the furnace cavity of the vertical curing furnace 100.

[0034] The vertical curing furnace 100 includes a first outer frame 101. A first feed inlet 102 is provided near the bottom on one side of the first outer frame 101, and a first discharge outlet 103 is provided near the top on the other side of the first outer frame 101. It further includes a first translation mechanism, a lifting mechanism, and a blanking hook mechanism disposed inside the first outer frame 101. The first translation mechanism is docked with the first feed inlet 102 and is used to send the supporting platform 300 into the furnace cavity. The lifting mechanism is used to lift the supporting platform 300 sent into the furnace cavity through the first feed inlet 102 to the height of the first discharge outlet 103. The blanking hook mechanism is used to translate the supporting platform 300 out of the furnace cavity from the first discharge outlet 103.

[0035] The auxiliary blanking device 200 includes a second outer frame 201. A second feed inlet docked with the first discharge outlet 103 is provided on the second outer frame 201, and a second discharge outlet 202 is provided on the other side of the second outer frame 201 opposite to the second feed inlet. It further includes a second translation mechanism, a lifting mechanism, and a cooling mechanism. The lifting mechanism includes a lifting platform 66. The second translation mechanism and the cooling mechanism are installed on the lifting platform 66. The second translation mechanism is used to receive the supporting platform 300 moved out of the first discharge outlet 103 at a high position and move the supporting platform 300 out of the auxiliary blanking device 200 through the second discharge outlet 202 at a low position. The cooling mechanism is used to cool the products on the supporting platform 300.

[0036] Further, the first translation mechanism includes a first motor 11, a first transmission rod 12, and a first sprocket structure 13. One side of the first transmission rod 12 is in transmission connection with the first motor 11, and the other side of the first transmission rod 12 is in transmission connection with the first sprocket structure 13.

[0037] Since the inside of the vertical curing furnace 100 is in a high-temperature state and a common conveyor belt structure cannot be used for feeding, a first translation mechanism that can withstand high temperatures is adopted to complete the feeding.

[0038] There are two groups of the first sprocket structures 13, and they are mirror-spaced between the two groups of the first sprocket structures 13. The chains at the top of the first sprocket structures 13 extend in the horizontal direction. When feeding, both sides of the supporting platform 300 are respectively pressed on the chains at the top of the two groups of the first sprocket structures 13. The first motor 11 provides power and drives the first sprocket structure 13 to operate through the first transmission rod 12, and translates the supporting platform 300 placed into the first feed inlet 102 into the furnace cavity for the lifting mechanism to pick up.

[0039] The structural principle and function of the second translation mechanism described below are roughly the same as those of the first translation mechanism, and will not be elaborated later. They both play the role of a conveyor belt and are used to horizontally move the supporting platform 300.

[0040] Further, the lifting mechanism includes a second motor 21, a second transmission rod 22, a bevel gear pair 23, a second sprocket structure 24, and a third transmission rod 25. One side of the second transmission rod 22 is in transmission connection with the second motor 21, and the other side of the second transmission rod 22 is in transmission connection with the bevel gear pair 23. The third transmission rod 25 is in transmission connection with the bevel gear pair 23 and the second sprocket structure 24. A guide bar 26 is fixed on the chain of the second sprocket structure 24, and a number of first rollers 27 are provided on the guide bar 26.

[0041] It should be noted that, for the convenience of showing the internal structure of the lifting mechanism, Figure 4 、 5 part of the guide bar 26 is hidden in

[0042] The bevel gear pair 23, the second sprocket structure 24, and the third transmission rod 25 are all in two groups, and the two groups of bevel gear pairs 23, second sprocket structures 24, and third transmission rods 25 are arranged at an interval in a mirror image. The second sprocket structure 24 provided with the guide bar 26 is similar to a crawler belt, and the second sprocket structure 24 in the middle extends in the vertical direction. After the first translation mechanism moves the supporting platform 300 into the furnace cavity, the second motor 21 drives the bevel gear pair 23 to rotate through the second transmission rod 22, and the bevel gear pair 23 drives the second sprocket structure 24 to rotate through the third transmission rod 25. When the second sprocket structure 24 in the middle moves upward, the first rollers 27 lift the supporting platform 300, so that the supporting platform 300 rises to a height close to the first blanking port 103.

[0043] It should be noted that the purpose of setting the first rollers 27 is to reduce the friction between the supporting platform 300 and the lifting mechanism, so that the resistance is smaller when moving the supporting platform 300 out of the furnace cavity.

[0044] Further, the blanking hook mechanism includes a third motor 31, a fourth transmission rod 32, a third sprocket structure 33, a mounting seat 34, a hook 35, and a first guide rod 36. The fourth transmission rod 32 is in transmission connection with the third motor 31 and the third sprocket structure 33. The hook 35 is fixed on the mounting seat 34, the mounting seat 34 is in transmission connection with the third sprocket structure 33, and the mounting seat 34 is in rolling contact with the first guide rod 36.

[0045] The first guide rod 36 extends in the horizontal direction and is used to guide the traveling direction of the mounting seat 34. The mounting seat 34 contacts the first guide rod 36 through rollers. The mounting seat 34 can reciprocate along the first guide rod 36 driven by the third sprocket structure 33. When the product on the supporting platform 300 is cured, the lifting mechanism lifts the supporting platform 300 to the height of the first discharge opening 103. The third motor 31 drives the mounting seat 34 to move towards the first discharge opening 103 through the fourth transmission rod 32 and the third sprocket structure 33. The hook 35 hooks the supporting platform 300 and moves the supporting platform 300 out of the first discharge opening 103, and then the third motor 31 drives the hook 35 to reset.

[0046] Further, the lifting mechanism further includes a fourth motor 61, two screw rods 62, a synchronous belt 63, a mounting strip 64, and a second guide rod 65. The mounting strip 64 is fixedly connected to the second outer frame 201. The top end of the second guide rod 65 is fixedly connected to the mounting strip 64, and the bottom end of the second guide rod 65 is fixedly connected to the second outer frame 201. The bottom end of one screw rod 62 is in transmission connection with the fourth motor 61, and the top end is in transmission connection with the top end of the other screw rod 62 through the synchronous belt 63. Both screw rods 62 are in threaded connection with the lifting platform 66, and both screw rods 62 are rotatably connected to the mounting strip 64.

[0047] The second guide rod 65 is arranged along the vertical direction and is used to guide the up and down movement of the lifting platform 66. The fourth motor 61 directly drives one screw rod 62 to rotate and drives the other screw rod 62 to rotate through the synchronous belt 63. Through the threaded cooperation between the screw rod 62 and the lifting platform 66, the lifting platform 66 can be driven to reciprocate in the vertical direction along the second guide rod 65.

[0048] Further, the second translation mechanism includes a fifth motor 51, a fifth transmission rod 52, and a fourth sprocket structure 53. One side of the fifth transmission rod 52 is in transmission connection with the fifth motor 51, and the other side of the fifth transmission rod 52 is in transmission connection with the fourth sprocket structure 53.

[0049] The fifth transmission rod 52 is connected to the output end of the fifth motor 51 and is used to drive the fourth sprocket structure 53 to operate. The chain at the top of the fourth sprocket structure 53 extends in the horizontal direction, and both sides of the supporting platform 300 moved out of the furnace cavity are pressed on the chain at the top of the fourth sprocket structure 53.

[0050] Further, the cooling mechanism includes a column 71, a cross frame 72, and a fan 73. The bottom of the column 71 is fixedly connected to the lifting platform 66. The cross frame 72 is fixedly installed on the top of the column 71. The fan 73 is installed on the cross frame 72 so that the fan 73 is suspended above the second translation mechanism.

[0051] The horizontal frame 72 is of a frame structure, and multiple upright columns 71 raise and fix the horizontal frame 72 above the second translation mechanism. The fan 73 is installed on the horizontal frame 72 and is used to cool the products on the lower supporting platform 300.

[0052] Furthermore, the vertical curing furnace 100 further includes an auxiliary translation mechanism. The auxiliary translation mechanism includes a sixth motor 91, a sixth transmission rod 92, and a base 93. The base 93 is provided with a second roller 94 and a rotating shaft 95. A rotating shaft gear pair 96 is arranged inside the base 93. One side of the sixth transmission rod 92 is in transmission connection with the sixth motor 91, the other side of the sixth transmission rod 92 is in transmission connection with the rotating shaft gear pair 96, and the rotating shaft gear pair 96 is in transmission connection with the rotating shaft 95.

[0053] The base 93 is installed on the fixed bracket inside the furnace cavity. The second roller 94 arranged on the base 93 is a non-powered mechanism and only serves to assist in supporting the supporting platform 300. The rotating shaft 95 arranged on the base 93 can rotate under the drive of the sixth motor 91 through the transmission of the sixth transmission rod 92 and the rotating shaft gear pair 96. The rotating rotating shaft 95 can provide assistance when the blanking hook claw mechanism moves the supporting platform 300 out of the furnace cavity, so that the supporting platform 300 can move more smoothly onto the second translation mechanism.

[0054] The working process of the present utility model is described as follows:

[0055] Place the circuit board product to be processed on the supporting platform 300, and place one end of the supporting platform 300 on the first translation mechanism through the first feeding port 102 (note that at this time, the first roller 27 of the lifting mechanism is misaligned with the supporting platform 300 in height). The first translation mechanism moves the supporting platform 300 into the furnace cavity. After the supporting platform 300 completely enters the furnace cavity, the lifting mechanism lifts the supporting platform 300 upward. At this time, the next supporting platform 300 can be continuously placed into the furnace cavity. During the upward movement of the supporting platform 300, the high temperature inside the furnace cavity completes the curing of the circuit board product.

[0056] After the circuit board product is cured, through the cooperation of the blanking hook claw mechanism and the auxiliary translation mechanism, the supporting platform 300 is transferred to the second translation mechanism of the auxiliary blanking device 200. The lifting mechanism lowers the height of the supporting platform 300 to the position of the second blanking port 202, and the second translation mechanism outputs the supporting platform 300 from the second blanking port 202. At the same time, during the downward movement of the supporting platform 300, the cooling mechanism will cool the circuit board product.

[0057] Compared with the prior art, the technical effect of the present utility model lies in:

[0058] The utility model is provided with an auxiliary blanking device 200 outside the furnace cavity of the vertical curing furnace 100. The process of lowering the height of the supporting platform 300 carrying the circuit board product and blanking is carried out outside the furnace cavity. Only a set of lifting mechanisms need to be reserved inside the furnace cavity, which helps to reduce the length dimension of the furnace cavity of the vertical curing furnace 100. The smaller furnace cavity volume makes it easier to uniformly control the temperature inside the furnace cavity, and it is especially suitable for the high-temperature curing process of flexible circuit boards for new energy vehicle battery packs.

[0059] By arranging a cooling mechanism on the auxiliary blanking device 200, the circuit board product after high-temperature curing can be cooled during the blanking process, improving the production efficiency.

[0060] By arranging an auxiliary translation mechanism, the supporting platform 300 can be transferred into the auxiliary blanking device 200 more smoothly.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
