Description

Technical Field

[0001] This utility model relates to the technical field of capacitor aging ovens, and in particular to an oven rack. Background Technology

[0002] Capacitor aging is a key reliability screening technology in electronic component manufacturing, specifically used in the production of aluminum electrolytic capacitors and some high-reliability film capacitors. Its core purpose is to accelerate the exposure of potential early failures and eliminate these defective products before they leave the factory, thereby improving the reliability and lifespan of the final product.

[0003] The core principle of capacitor aging is to apply electrical and thermal stress (usually voltage and temperature) far exceeding normal operating conditions to the capacitor. In a short period of time, the stress forces the electrolyte to repair the tiny weak points on the anodic oxide film (dielectric layer), causing capacitors with serious defects (such as impurities, poor sealing, and dielectric defects) to fail within the specified aging time (such as short circuit, open circuit, a sharp increase in leakage current, and a sudden drop in capacitance). This makes the performance of the screened capacitors tend to stabilize, and the leakage current drops to the qualified range and remains stable.

[0004] For example, Chinese patent document CN222528276U discloses a capacitor aging oven, which discloses a baking chamber mounted on a rack. The baking chamber is used to house and bake capacitors for aging tests. Existing capacitor aging ovens, in order to improve aging efficiency, place multiple capacitors inside for simultaneous aging tests. Each capacitor requires an independent electrical signal testing system, meaning that the oven needs to accommodate a large number of wires, testing modules, and other components, all mounted on the rack. With the development of capacitor technology, the electrical signal testing systems for capacitor aging tests also need to be updated and upgraded, requiring corresponding replacements and upgrades of components within the aging oven. However, existing racks use a common single-door structure. When replacing or upgrading the aging oven, operators must open the single door and lean their upper bodies into the equipment to operate it. The existing oven structure has a narrow internal space, making replacement and maintenance extremely inconvenient. Therefore, this application proposes an oven rack that is easier for personnel to operate. Utility Model Content

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figures 1 to 4 As shown, an oven rack 10 includes a frame 100 and a rear-opening assembly 200. The frame 100 includes an inner frame 110 and an outer frame 120. The inner frame 110 is disposed inside the outer frame 120, and the front side of the inner frame 110 is flush with the front side of the outer frame 120. A first space 101 is formed between the two sides of the inner frame 110 and the two sides of the outer frame 120. A second space 102 is formed between the rear side of the inner frame 110 and the rear side of the outer frame 120. A plurality of crossbars 130 are spaced apart on the inner frame 110, and each crossbar 130 divides the inner frame 110 into a plurality of inner liner embedding areas 103. 03 is used to install the baking oven. The rear opening assembly 200 includes two door frames 210 and several cable trays 220. The two door frames 210 are rotatably mounted on the rear ends of the outer frame 120. Each door frame 210 is provided with several rollers 230 at its bottom. When the door frame 210 is subjected to force to rotate relative to the outer frame 120, the door frame 210 is housed in or away from the second space 102. Each cable tray 220 is spaced apart on the outer frame 120, and each cable tray 220 passes through the first space 101 so that its two ends are connected to the inner frame 110 and the door frame 210 respectively.

[0030] It should be noted that the inner frame 110 is welded inside the outer frame 120, with the front side of the inner frame 110 flush with the front side of the outer frame 120. The area between the two sides of the inner frame 110 and the two sides of the outer frame 120 forms a first space 101, and the area between the rear side of the inner frame 110 and the rear side of the outer frame 120 forms a second space 102. The gantry 210 is rotatably mounted on both ends of the rear side of the outer frame 120 via a pivot, allowing the gantry 210 to rotate relative to the outer frame 120. Thus, when the gantry 210 is rotated under force, it is either closed within the second space 102 or opened from the second space 102. Each cable tray 220 can be welded to the outer frame 120 or fixed to it with screws. The cable tray 220 is located within the first space 101, with both ends of the cable tray 220 connected to the inner frame 110 and the gantry 210, respectively. Thus, the inner liner embedding area 103 is used to install the baking oven. The wires used for testing capacitors, supplying power for heating, and blowing air inside the baking oven can all be led out from the inner frame 110 through the cable tray 220 to the gantry 210. Therefore, when maintenance or upgrades are needed, the gantry 210 can be opened from the second space 102, allowing the operator to stand between the two gantry 210s and operate the components inside the inner frame 110 or on the gantry 210 without having to lean their upper body into the equipment, making it more convenient to use. It should be noted that multiple rollers 230 are installed at the bottom of the gantry 210, with the rollers 230 in contact with the ground. This use of the rollers 230 to support the gantry 210 improves its stability.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of crossbeams 240 are provided on the gantry 210, and the crossbeams 240 are spaced apart from each other. In this way, the crossbeams 240 divide the gantry 210 into several layers, so that components such as test modules and circuit boards can be mounted on the crossbeams 240.

[0032] like Figure 1 As shown, in one embodiment, a rear door panel 250 is provided on the outer side of the gantry 210. Specifically, the rear door panel 250 is installed on the outer side of the gantry 210 by welding or by screwing.

[0033] like Figure 1 As shown, in one embodiment, side plates 140 are detachably provided on both sides of the outer frame 120.

[0034] It should be noted that the side plate 140 is fastened to the outer frame 120 with screws. When maintenance or repair is required, the side plate 140 can be removed from the outer frame 120 for easy operation.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, a top plate 150 is provided on the top of the outer frame 120. Specifically, the top plate 150 is also installed on the top of the outer frame 120 by screws. In this way, under the action of the rear door panel 250, the side panel 140, and the top plate 150, a sealed environment is formed inside the outer frame 120.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of cooling fans 160 are provided on the top plate 150. Thus, when the heat in the oven is transferred to the second space 102 and the first space 101 and the temperature becomes too high, the cooling fans 160 on the top plate 150 can accelerate the heat dissipation of the first space 101 and the second space 102.

[0037] like Figure 1 As shown, in one embodiment, the front side of the inner frame 110 is rotatably provided with a plurality of front sealing doors 170, each front sealing door 170 being used to seal the front side of each baking oven respectively.

[0038] It should be noted that the front sealing door 170 is rotatably mounted on the front side of the inner frame 110 via a pin, so that the front sealing door 170 can rotate relative to the inner frame 110, thereby allowing the front sealing door 170 to easily seal the front opening of the oven.

[0039] like Figure 1 As shown, in one embodiment, the rear side of the inner frame 110 is rotatably provided with a plurality of rear sealing doors 180, each rear sealing door 180 being used to seal the rear side of each baking oven respectively.

[0040] It should be noted that the rear sealing door 180 is also rotatably mounted on the rear side of the inner frame 110 via a pin, so that the rear sealing door 180 can easily seal the rear opening of the oven.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of cylinders 190 are spaced apart on both sides of the inner frame 110, so that the two ends of each front sealing door 170 and rear sealing door 180 are respectively connected to the output shaft of a cylinder 190.

[0042] It should be noted that the opening and closing of the front sealing door 170 and the rear sealing door 180 are controlled by cylinder 190, eliminating the need for manual operation by the operator and making it more convenient to use. Each of the front sealing door 170 and the rear sealing door 180 is connected at both ends to the output shaft of cylinder 190, thus ensuring the stability of the movement of the front sealing door 170 and the rear sealing door 180, thereby enabling the oven to be sealed stably.

[0043] like Figure 1 and Figure 2As shown, in one embodiment, the bottom of the outer frame 120 is provided with a plurality of legs 1100 spaced apart. Thus, the legs 1100 support the outer frame 120, facilitating the insertion of a forklift into the bottom of the outer frame 120 to transfer the oven rack 10 of this application. Further, in one embodiment, the bottommost point of the legs 1100 and the bottommost point of the rollers 230 are located on the same plane. Thus, when the legs 1100 are placed on the ground, the mast 210 contacts the ground via the rollers 230, thereby ensuring the stability of the mast 210.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
