Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature drying and chemical formation, in particular to a high-capacity cooling device and a heating device. Background Art

[0002] During the manufacturing process, electronic components such as tantalum capacitors need to be baked to remove residual moisture and volatile substances inside them. Appropriate baking temperature is of great significance to the quality and service life of electronic components. Taking tantalum capacitors as an example, the baking temperature of tantalum capacitors usually depends on the specific process requirements and manufacturing standards. Generally speaking, the baking temperature of tantalum capacitors needs to be carried out at a high temperature of 250°C. The high temperature of 250°C can effectively remove the residual moisture and volatile substances inside the tantalum capacitor and ensure the stability and reliability of the tantalum capacitor. Tantalum capacitors are generally baked in high-temperature drying and forming equipment, and then taken out for natural cooling or artificial cooling after baking.

[0003] However, the prior art generally lays or stacks the racks containing tantalum capacitors after baking for cooling. Since cooling takes a certain amount of time, and when there are many racks, laying or stacking a large number of racks will occupy a large amount of space, which will undoubtedly increase the space occupation cost and have low space utilization. In addition, stacking the racks will affect the heat dissipation effect of the tantalum capacitor, thereby affecting the performance of the tantalum capacitor. In addition, the cooling process of the tantalum capacitor in the prior art is static, and the cooling efficiency is low, and the artificial creation of air flow will increase the cooling cost.

[0004] Therefore, high-capacity cooling devices and heating equipment are urgently needed to solve the above-mentioned defects. Utility Model Content

[0025] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0026] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0027] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0028] See also Figure 1-Figure 8 The heating equipment of this embodiment includes a drying and forming furnace (not shown in the figure), a feeding mechanism (not shown in the figure) and a high-capacity cooling device. The drying and forming furnace is used to dry electronic components such as tantalum capacitors. The electronic components are generally placed on a rack 1. The feeding mechanism takes the rack 1 out of the drying and forming furnace and transfers it to the high-capacity cooling device so that the electronic components can be cooled in the high-capacity cooling device.

[0029] The high-capacity cooling device includes an operating mechanism 10 and a driving mechanism 20, wherein the operating mechanism 10 includes a guide rail assembly 11, a carrying trolley 12 and a bracket 13 for supporting the object to be cooled, the guide rail assembly 11 is arranged in a ring shape, the carrying trolley 12 is connected to the bracket 13, the carrying trolley 12 is limited on the guide rail assembly 11 to make a ring-shaped circulation movement to drive the bracket 13 to make a ring-shaped circulation movement along the guide rail assembly 11, and the driving mechanism 20 is used to drive the carrying trolley 12 to make a ring-shaped circulation movement on the guide rail assembly 11.

[0030] Preferably, the guide rail assembly 11 includes two linear guide rails 111 and two symmetrically arranged arc guide rails 112, and the two linear guide rails 111 and the two arc guide rails 112 together form a circular moving path. Specifically, the arc guide rail 112 is arranged in a semicircular shape, and the two linear guide rails 111 and the two arc guide rails 112 together form a runway-shaped moving path.

[0031] It is understandable that the circulation path here occupies the lateral space and the longitudinal space, and transporting multiple brackets 13 at intervals along the annular moving path can greatly increase the placement capacity of the rack 1 under the combination of the lateral space and the longitudinal space. The distance between the two linear guide rails 111 here needs to be greater than the width of the two racks 1 to avoid the rack 1 from falling or operating failure due to interference of the rack 1 during the cyclic movement of multiple brackets 13. In addition, in order to be suitable for the circular operation of the machine, the moving path of this embodiment is a standard ring, which provides a sufficiently high load-bearing space and a sufficiently wide rotation space for cooling and transmission. Of course, in other preferred embodiments, the moving path can be a ring-shaped path composed of curves, which is not limited here.

[0032] Preferably, the high-capacity cooling device further comprises a rack 30, and the rack 30 comprises frames 31 arranged opposite to each other along the X-axis direction, and there is a certain space between the two frames 31. Each frame 31 is equipped with an operating mechanism 10, and the two operating mechanisms 10 are arranged opposite to each other and symmetrically, the supporting surface of the bracket 13 is always kept horizontally upward, and every two brackets 13 are always kept at the same level to jointly support the material to be cooled. It can be understood that the material rack 1 circulates between the two frames 31. During the operation, in order to prevent the material rack 1 from tipping over or falling, it is necessary to ensure that the supporting surface of the bracket 13 is always kept horizontally upward, and every two brackets 13 are always kept at the same level to jointly support the material rack 1 loaded with the material to be cooled.

[0033] Preferably, the operating mechanism 10 also includes a transmission assembly, which includes a driving shaft 141, a driving wheel 142, a driven shaft 143, a driven wheel 144, a transmission bar 145 and a first connecting rod 146. The driving shaft 141 and the driven shaft 143 are arranged on the frame 31 at intervals along the X-axis direction. The first connecting rod 146 is respectively connected to the two driving shafts 141. The function of the first connecting rod 146 is that only one driving mechanism 20 is needed to drive the two driving wheels 142 to rotate synchronously.

[0034] The transmission bar 145 meshes with the driving wheel 142 and the driven wheel 144 in sequence, the carrying trolley 12 is connected to the transmission bar 145, and the output end of the driving mechanism 20 is connected to one of the two driving shafts 141. The driving mechanism 20 here includes but is not limited to a motor and a cylinder. The driving motor drives one of the two driving shafts 141 to rotate about its axis, thereby driving the entire transmission bar 145 to rotate in a circular manner. Since the carrying trolley 12 is connected to the transmission bar 145, at this time, the carrying trolley 12 can perform a circular movement on the guide rail assembly 11. Connecting multiple carrying trolleys 12 to the transmission bar 145 at specific intervals can achieve a circular movement of multiple carrying trolleys 12 on the guide rail assembly 11 at the same time, so as to achieve maximum space utilization.

[0035] In addition, the driving wheel 142 and the driven wheel 144 of the present embodiment are sprocket wheels, and at this time, the transmission bar 145 corresponds to a chain. Of course, in other embodiments, the driving wheel 142 and the driven wheel 144 can also be rollers, and at this time, the transmission bar 145 corresponds to a belt.

[0036] Preferably, the transport trolley 12 includes a body body 121 and a first roller assembly, a transmission bar 145 is connected to the body body 121, the first roller assembly includes a plurality of first rollers 122, the body body 121 is arranged in an I-shape, and the first rollers 122 are respectively installed on the two upper edges and the two lower edges corresponding to the I-slot 1211 of the body body 121, and the frame 31 is provided with a roller guide rail 311 for the first roller 122 to roll, and the roller guide rail 311 includes a first guide rail 3111 and a second guide rail 3112, the first rollers 122 on the upper and lower sides corresponding to one of the I-slots 1211 of the body body 121 roll against the first guide rail 3111 together, and the first rollers 122 on the upper and lower sides corresponding to the other I-slot 1211 roll against the second guide rail 3112 together.

[0037] Specifically, the carrying trolley 12 also includes an auxiliary rotating shaft 123, a cross-shaped mounting plate 124 and a second roller assembly. The middle section of the auxiliary rotating shaft 123 is fixed to the vehicle body 121 through a bearing. One end of the auxiliary rotating shaft 123 is connected to the bracket 13, and the other end is connected to the plane center point of the cross-shaped mounting plate 124. At this time, the relative positions of the cross-shaped mounting plate 124 and the bracket 13 are fixed, and the vehicle body 121 can use the auxiliary rotating shaft 123 as the rotating shaft to rotate relative to the cross-shaped mounting plate 124 and the bracket 13.

[0038] The second roller assembly includes a first auxiliary wheel 1251, a second auxiliary wheel 1252 and two third auxiliary wheels 1253. The cross-shaped mounting plate 124 includes a first mounting bar 1241 and a second mounting bar 1242 that are perpendicular to each other. The first mounting bar 1241 and the second mounting bar 1242 have the same shape and are connected concentrically. The center point of the first mounting bar 1241 and the second mounting bar 1242 is the plane center point of the cross-shaped mounting plate 124. The first mounting bar 1241 is parallel to the supporting surface of the bracket 13, and the second mounting bar 1242 is perpendicular to the supporting surface of the bracket 13. The first auxiliary wheel 1251 is installed at one end of the first mounting bar 1241 facing the surface where the vehicle body 121 is located, and the second auxiliary wheel 1252 is installed at the other end. The first auxiliary wheel 1251 and the second auxiliary wheel 1252 are at different distances from the vehicle body 121. The third auxiliary wheels 1253 are installed at both ends of the second mounting bar 1242 facing away from the surface where the vehicle body 121 is located.

[0039] The high-capacity cooling device further includes a guide mechanism, which includes a first guide arc plate 41, a second guide arc plate 42 and a third guide arc plate 43. The arc guide rail 112 includes Figure 8 As shown, the first arc segment 1121 and the second arc segment 1122 are connected in sequence, and the first arc segment 1121 and the second arc segment 1122 are spliced ​​in sequence to form the arc guide rail 112 .

[0040] When the transport trolley 12 enters the first arc section 1121, one of the first auxiliary wheel 1251 and the second auxiliary wheel 1252 rolls and abuts the arc wall of the first guide arc plate 41, the other is suspended in the air, and one of the two third auxiliary wheels 1253 rolls and abuts the arc wall of the third guide arc plate 43; when the transport trolley 12 enters the second arc section 1122, one of the first auxiliary wheel 1251 and the second auxiliary wheel 1252 rolls and abuts the arc wall of the second guide arc plate 42, the other is suspended in the air, and one of the two third auxiliary wheels 1253 rolls and abuts the arc wall of the third guide arc plate 43, the auxiliary rotating shaft 123, the cross-shaped mounting plate 124 and the second roller assembly jointly keep the supporting surface of the bracket 13 corresponding to the transport trolley 12 entering the arc guide rail 112 always horizontally upward.

[0041] Specifically, the first guide arc plate 41, the second guide arc plate 42 and the third guide arc plate 43 are staggered along the Y-axis direction, so that there is enough avoidance space between the first auxiliary wheel 1251, the second auxiliary wheel 1252 and the third auxiliary wheel 1253 to meet the switching abutment. At this time, since the second roller assembly always has two wheels that can roll and abut on the corresponding arc wall, combined with the rolling abutment of the first roller assembly on the roller guide rail 311, the supporting surface of the bracket 13 is always kept horizontal and upward.

[0042] Furthermore, the projections of the first guide arc plate 41 and the second guide arc plate 42 along the Y-axis direction overlap. By reasonably setting the overlapping degree of the projections of the first guide arc plate 41 and the second guide arc plate 42 along the Y-axis direction, when the transport trolley 12 moves to the connection between the first arc segment 1121 and the second arc segment 1122, the first auxiliary wheel 1251, the second auxiliary wheel 1252 and one of the third auxiliary wheels 1253 can roll and abut against the corresponding arc wall, thereby making the movement of this part more stable.

[0043] Preferably, the guide mechanism further includes a transmission guide bar 44, and the transmission guide bar 44 is used to guide the transmission bar 145 to transmit along a preset track to avoid transmission failure caused by the transmission guide bar 44 deviating from the preset track.

[0044] When the material needs to be collected after cooling, the collecting platform can be moved between the two frames 31 and located on the descending side of the material rack 1 along the moving path. The material rack 1 descended to the collecting platform is supported by the collecting platform, and the bracket 13 continues to move along the moving path to realize the material collecting operation.

[0045] Combination Figure 1-Figure 8 The guide rail assembly 11 of the utility model is arranged in a ring shape, and the carrying trolley 12 is connected to the bracket 13. The carrying trolley 12 is limited on the guide rail assembly 11 to make a ring-shaped circulation movement to drive the bracket 13 to make a ring-shaped circulation movement along the guide rail assembly 11. The driving mechanism 20 is used to drive the carrying trolley 12 to make a ring-shaped circulation movement on the guide rail assembly 11. On the one hand, the carrying trolley 12 makes a ring-shaped circulation movement on the guide rail assembly 11, and the ring-shaped circulation movement is used to maximize the use of the horizontal space and the longitudinal space to accommodate the objects to be cooled, which greatly improves the space utilization rate and space capacity; on the other hand, the objects to be cooled are always moving in a ring-shaped circulation during the cooling process, and the movement process will accelerate the air flow. The flowing air formed during the movement process is used to further improve the cooling effect, and there is no need to accelerate the cooling by artificially creating air flow, which effectively saves the cooling cost; on the other hand, during the cooling process, there is a certain distance between the objects to be cooled on different racks 1, which effectively avoids affecting the performance of the objects to be cooled due to the stacking of the racks 1.

[0046] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention.
