Description

Technical Field

[0001] The utility model relates to the technical field of vertical furnaces, and particularly relates to an adjustment structure of a vertical furnace for processing an electromagnetic induction cooker circuit board. Background Art

[0002] A vertical curing furnace, abbreviated as a vertical furnace, is a common device in the electronics industry. The vertical curing furnace has the characteristics of high efficiency. It adopts advanced heating technology, can quickly heat materials to a set temperature, and can improve production efficiency. Moreover, compared with traditional heating methods, the heating effect of the vertical furnace is more uniform, which can effectively avoid uneven problems generated during the heating process of materials.

[0003] The vertical furnace is often used in the production of circuit boards. For equipment applied to the production of circuit boards, reference can be made to a vertical transmission mechanism and a vertical curing furnace applying the same, disclosed in Chinese Patent Publication No. CN209753326U, which specifically includes a furnace body, a transmission mechanism, and a heating mechanism; a feeding port is arranged on one side of the furnace body, and a discharging port is arranged on the other side; the transmission mechanism includes a first horizontal transmission structure arranged at the feeding port, a second horizontal transmission structure arranged at the discharging port, a first vertical transmission structure for receiving products transmitted by the first horizontal transmission structure, a second vertical transmission structure for transmitting products to the second horizontal transmission structure, and a driving mechanism for driving products from the first vertical transmission structure to the second vertical transmission structure; the structure for horizontally transmitting the belt is improved into a structure for vertically transmitting.

[0004] For the existing vertical curing furnace, in order to realize synchronous driving between two vertical transmission structures, a combined structure of a worm gear and a worm is usually adopted. The worm drives the turbine, and then the turbine drives the transmission roller, and the transmission roller drives the transmission belt to rotate in a cycle. A plurality of support bars are arranged on the transmission belt, and the movement of two support bars in the z direction in the conveying channel drives the circuit board to lift. However, as the service life of the equipment increases, the turbine will be worn. In the conventional structure, the worm gear is directly fixed to the end of the transmission roller. Since the worm gear cooperates with the worm, adjusting one of the turbines will cause all turbines to rotate synchronously. Therefore, the horizontal height of one side of the support bar cannot be finely adjusted. When the circuit board enters the board later, due to the non-parallelism of the left and right support bars, the patch components on the circuit board will fall off, skew and other defects, and it is also easy to cause an increase in the loss of the circuit board material, and this situation is particularly serious for long-board circuit boards.

[0005] Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0006] In view of the deficiencies of the above-mentioned prior art, the purpose of the present utility model is to provide a vertical furnace adjustment structure for processing induction cooker circuit boards, so as to solve the problem that the existing vertical curing furnace cannot adjust the relative horizontal heights of the left and right support bars.

Each vertical lifting mechanism includes a bracket, driving rollers rotatably arranged at the upper and lower ends of the bracket, a transmission belt drivingly connected to the two driving rollers, and a plurality of support bars are arranged on the transmission belt. The support bars located in the channel are used to drive the circuit board to lift along the z direction;

[0009] A synchronous lifting drive mechanism, including a worm gear assembly drivingly connected to the driving roller, a worm meshingly connected to the worm gear assembly, a transmission rod for driving the worm to rotate, and a driving device for driving the transmission rod. The worm gear assembly includes a worm gear, an adjusting member, and a locking member. The adjusting member is fixed to the end of the driving roller, the worm gear is rotatably arranged at the end of the driving roller. At least one adjusting hole is provided on the adjusting member. The locking member passes through the adjusting hole to fix the adjusting member and the worm gear, and the position of the locking member in the adjusting hole is adjustable.

[0010] Specifically, a through hole for the end of the driving roller to pass through is provided in the middle of the adjusting member. A groove recessed outward is provided at the edge of the through hole. A clamping member matched with the groove is connected to the end of the driving roller. A locking hole is provided at one end of the clamping member facing the groove. A positioning hole corresponding to the position of the locking hole is connected to the groove. The worm gear assembly further includes a first locking screw. After the first locking screw passes through the positioning hole, it is threadedly connected to the locking hole.

[0011] Specifically, a notch is provided between adjacent two adjusting holes, and a side hole for installing a second locking screw is provided between the adjusting hole and the notch.

[0012] Specifically, the distance of the channel along the x direction is adjustable.

[0013] Specifically, the vertical furnace adjustment structure further includes a distance adjustment mechanism for driving one of the vertical lifting mechanisms along the x direction. The distance adjustment mechanism includes a lead screw module and a sliding seat connected to the output end of the lead screw module. The sliding seat is fixed to the bracket of the vertical lifting mechanism that can move along the x direction.

[0014] Specifically, the synchronous lifting drive mechanisms are provided on both sides of the vertical lifting mechanism along the y direction. The drive device includes a driven wheel in transmission connection with the transmission rod, a driving wheel in transmission with the driven wheel through a belt, and a motor for driving the driving wheel.

[0015] Specifically, an oil receiving groove is further provided below the worm gear assembly.

[0016] Advantages of the present utility model:

[0017] The vertical furnace adjustment structure of the present application can be applied to a vertical furnace. A synchronous lifting drive mechanism is provided. The drive device drives the transmission rod to rotate, and the transmission rod simultaneously drives two worm gears to rotate. The two worm gears respectively drive two worm gear assemblies, and the two worm gear assemblies respectively drive two transmission rollers to rotate, so as to realize the lifting and conveying actions of the two vertical lifting mechanisms on the circuit board. The structure is ingenious; when the support bars on both sides of the channel are not parallel, tools such as a screwdriver can be used to first loosen the locking member to make the adjusting member no longer fixed to the worm gear, and then rotate the adjusting member. The rotation of the adjusting member drives the rotation of the transmission roller, thereby driving the endless rotation of the transmission belt, so that the support bars located in the channel can be adjusted in height along the z direction, so that the support bars on both sides of the channel can be parallel, and the subsequent circuit board can enter the channel parallelly, avoiding adverse phenomena such as the falling off and skew of the surface-mounted components on the circuit board during later processing, and also avoiding situations such as the jamming and breaking of the long-board circuit board.

Detailed implementation manners

[0031] The present utility model provides a vertical furnace adjustment structure for electromagnetic induction cooker circuit board processing. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the attached drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] Please refer to Figures 1 to 11 , this embodiment discloses a vertical furnace adjustment structure for electromagnetic induction cooker circuit board processing, including:

[0034] The vertical lifting mechanism 10 has two and is arranged side by side along the x direction. There is a channel 30 for conveying the circuit board 20 along the y direction between the two vertical lifting mechanisms 10. The vertical lifting mechanism 10 includes a bracket 11, a driving roller 12 rotatably arranged at the upper and lower ends of the bracket 11, and a transmission belt 13 drivingly connected to the two driving rollers 12. A plurality of support bars 14 are provided on the transmission belt 13, and the support bars 14 located in the channel 30 are used to drive the circuit board 20 to lift along the z direction;

[0035] The synchronous lifting drive mechanism 40 includes a worm gear assembly 41 drivingly connected to the driving roller 12, a worm 42 meshingly connected to the worm gear assembly 41, a transmission rod 43 for driving the worm 42 to rotate, and a driving device 44 for driving the transmission rod 43. The worm gear assembly 41 includes a worm gear 411, an adjusting member 412, and a locking member 413. The adjusting member 412 is fixed to the end of the driving roller 12. The worm gear 411 is rotatably arranged at the end of the driving roller 12. At least one adjusting hole 4121 is provided on the adjusting member 412. The locking member 413 passes through the adjusting hole 4121 to fix the adjusting member 412 and the worm gear 411, and the position of the locking member 413 in the adjusting hole 4121 is adjustable.

[0036] The vertical furnace adjustment structure of this embodiment can be applied to a vertical furnace. By setting two vertical lifting mechanisms 10 arranged side by side along the x direction, after a batch of circuit boards 20 are conveyed into the channel 30, the circuit boards 20 are intermittently supported along the z direction by the support bars 14 on both sides of the channel 30. By controlling the rotation of the driving roller 12, the transmission belt 13 is driven to rotate in a cycle, so that the support bars 14 in the channel 30 drive the circuit board 20 to lift along the z direction. By pre-storing a large number of circuit boards 20 and coordinating the lifting to control the height of the circuit board 20, compared with the traditional horizontal curing furnace, the vertical furnace can store more circuit boards 20 and has higher production efficiency during the same process treatment time.

[0037] Moreover, this embodiment is provided with a synchronous lifting drive mechanism 40. The driving device 44 drives the transmission rod 43 to rotate, and the transmission rod 43 simultaneously drives the two worms 42 to rotate. The two worms 42 respectively drive the two worm gear assemblies 41, and the two worm gear assemblies 41 respectively drive the two driving rollers 12 to rotate, so as to realize the lifting and conveying actions of the two vertical lifting mechanisms 10 on the circuit board 20, and the structure is ingenious.

[0038] In addition, the worm wheel assembly 41 of this embodiment includes a worm wheel 411, an adjusting member 412, and a locking member 413. When the support bars 14 on both sides of the channel 30 are not parallel, tools such as a screwdriver can be used to first loosen the locking member 413, so that the adjusting member 412 and the worm wheel 411 are no longer fixed. Then, the adjusting member 412 is rotated. The rotation of the adjusting member 412 drives the rotation of the driving roller 12, thereby driving the endless rotation of the conveyor belt 13, enabling the support bars 14 located in the channel 30 to adjust their heights in the z direction, so that the support bars 14 on both sides of the channel 30 can be parallel. Subsequently, the circuit board 20 can enter the channel 30 in parallel, avoiding poor phenomena such as the falling off and skewing of the surface-mounted components on the circuit board 20 during later processing, and also avoiding situations such as the circuit board 20 getting stuck or broken.

[0039] Please refer to Figures 8 to 11 , a through hole for the end of the driving roller 12 to pass through is provided in the middle of the adjusting member 412 of this embodiment. A groove is provided on the edge of the through hole and recessed outward. A clamping member 121 is connected to the end of the driving roller 12 and is matched with the groove. Through the cooperation of the clamping member 121 and the groove, the synchronous rotation of the driving roller 12 and the adjusting member 412 is realized. When the user needs to adjust the parallelism of the support bars 14 on both sides of the channel 30, by rotating the adjusting member 412, the rotation of the driving roller 12 can be driven; in addition, in order to prevent the worm wheel 411 from rotating synchronously when the adjusting member 412 rotates and adjusts, causing the corresponding rotation of the worm wheels 411 in other positions, a circular hole can be designed in the middle of the worm wheel 411, and the end of the driving roller 12 passes through the circular hole and can rotate in the circular hole. With such a setting, when the locking member 413 is loosened, the adjusting member 412 and the worm wheel 411 are no longer fixed. Then, when the adjusting member 412 is rotated, the worm wheel 411 will not rotate accordingly, and the structure is ingenious.

[0040] Further, please refer to Figure 10 , a locking hole 122 is provided at one end of the clamping member 121 facing the groove. A positioning hole 4122 corresponding to the position of the locking hole 122 is connected to the groove. The worm wheel assembly 41 further includes a first locking screw. After the first locking screw passes through the positioning hole 4122, it is threadedly connected to the locking hole 122. The end of the driving roller 12 is locked by the first locking screw to prevent the worm wheel assembly 41 from moving axially along the driving roller 12.

[0041] Further, please refer to Figure 8 and Figure 9A cutout 4123 is provided between two adjacent adjustment holes 4121 to facilitate the user to rotate the adjustment piece 412, and a side hole 4124 for inserting a second locking screw is provided between the adjustment hole 4121 and the cutout 4123. Second locking screws are provided on both sides of the same adjustment hole 4121 along the rotation adjustment direction. The second locking screw supports the first locking screw laterally. In actual operation, the position is calibrated by turning the two second locking screws, so as to more effectively limit the first locking screw in the adjustment hole 4121, improve the fixing effect of the adjustment piece 412 and the worm gear 411, and prevent the adjustment piece 412 from deflecting, thereby affecting the parallelism of the support bars 14 on both sides of the channel 30.

[0042] In order to adapt to the production and processing of circuit boards 20 of different specifications, the distance of the channel 30 along the x-direction is adjustable. Specifically, one of the vertical lifting mechanisms 10 is designed to be movable along the x-direction, and the other vertical lifting mechanism 10 is designed to be a fixed position structure. The vertical furnace adjustment structure also includes a distance adjustment mechanism 50 for driving one of the vertical lifting mechanisms 10 along the x-direction. The distance adjustment mechanism 50 includes a screw module 51 and a sliding seat 52 connected to the output end of the screw module 51. The sliding seat 52 is fixed on the bracket 11 of the vertical lifting mechanism 10 movable along the x-direction. The sliding seat 52 is driven by the screw module 51, thereby driving the sliding seat 52 to move along the x-direction to adjust the distance of the channel 30 along the x-direction.

[0043] Please refer to Figure 6 and Figure 7 In order to realize the synchronous rotation of the two transmission rods 43, the vertical lifting mechanism 10 is provided with a synchronous lifting driving mechanism 40 on both sides along the y direction. The driving device 44 includes a driven wheel 441 connected to the transmission rod 43, a driving wheel 443 driven by the driven wheel 441 through a belt 442, and a motor 444 for driving the driving wheel 443. Through such a structural design, the synchronous action of the two can be guaranteed and the cost of the device can be reduced.

[0044] Please refer to Figure 6 The worm gear assembly 41 and the worm 42 are usually coated with lubricating oil to reduce friction and improve mechanical properties. During use, the lubricating oil is easy to drip. For this reason, this embodiment further provides an oil receiving groove 60 under the worm gear assembly 41 for collecting the lubricating oil dripping from the worm gear assembly 41.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
