Description

Technical Field

[0001] The invention belongs to the technical field of solder paste storage, and in particular relates to a solder paste bottle storage device capable of preventing the solder paste bottle from being loaded upside down. Background Art

[0002] Solder paste is used in the electronics manufacturing industry and is a key soldering material in the SMT (Surface Mount Technology) process. Solder paste is primarily a stable, paste-like mixture of alloy solder powder and a flux carrier. Due to its unique properties, solder paste requires refrigeration at temperatures between 0°C and 10°C. Therefore, solder paste is typically stored in bottles in a freezer.

[0003] When storing solder paste, bottles are typically placed in racks and then refrigerated in freezers. However, due to the busy schedule at production sites, workers often load solder paste bottles in random directions, resulting in some bottles being loaded into the rack with their caps facing outward or others with their bottoms facing outward. Therefore, it is crucial to design a storage device that can control the loading direction of solder paste bottles to prevent them from being loaded upside down. Summary of the Invention

[0004] In view of the technical problems in the prior art that staff arbitrarily load solder paste bottles into storage racks, some of the solder paste bottles have their caps facing outwards and some have their bottoms facing outwards during storage, and the solder paste bottles are irregularly arranged, which easily leads to excessive space occupation and inconvenience in access, the present invention provides a solder paste bottle storage device that can prevent the solder paste bottles from being loaded upside down.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The bottle is capped at the bottom end of the bottle and has a slot for holding the bottle in a predetermined position so that the bottle can be loaded into the container and the container can be opened and closed. The first foolproof part and the second foolproof part at the entrance are arranged on the side of the panel close to the entrance and in front of the second foolproof part, the first foolproof part and the second foolproof part are staggered with each other along the loading direction of the solder paste bottle, the first foolproof part and the second foolproof part are spaced from each other on the projection plane perpendicular to the loading direction, the space formed between the first foolproof part and the second foolproof part can allow the bottle body to enter, and can also block the bottle cap from entering, the distance between the rear side surface of the first foolproof part facing the slide rail and the back plate is greater than the axial length of the solder paste bottle, a side surface of the first foolproof part facing the second foolproof part is defined as a first arc surface with a diameter adapted to the outer diameter of the bottle cap, and a side surface of the second foolproof part facing the first foolproof part is defined as a second arc surface with a diameter adapted to the outer diameter of the bottle body;

[0007] On the orthographic projection surface, the first arc surface and the second arc surface are concentrically distributed;

[0008] On the orthographic projection surface, the straight-line distance from the first arc surface to the second arc surface and through the center of the first arc surface is greater than the diameter of the second arc surface but smaller than the diameter of the first arc surface. The first arc surface and the second arc surface cooperate with each other to limit each solder paste bottle to enter the inlet only with the bottom facing backward and the cap facing forward.

[0009] Furthermore, the storage components are limited to several groups, and the several groups of storage components are arranged in sequence along the front-to-back direction. The several groups of storage components are connected into one by connecting parts, and the connecting parts are limited to be set as support plates, and the lower end of the back plate of each of the storage components is connected to the support plate; wherein, the inlet of the storage components of the latter group is exposed to the outside of the inlet of the storage components of the former group, and the outlet of the storage components of the latter group is exposed to the outside of the outlet of the storage components of the former group.

[0010] Furthermore, the first end of the slide rail not covered by the panel is the entrance, and the second end not covered by the panel is the exit.

[0011] Furthermore, the second fool-proofing component is arranged on the slide rail and is arranged opposite to the first fool-proofing component on the orthographic projection plane.

[0012] Furthermore, the orthographic projection of the slide rail or the slide rail and the panel is serpentine;

[0013] The slide rail comprises a first side rail and a second side rail parallel to the first side rail; the parallel distance between the first side rail and the second side rail is adapted to the outer diameter of the bottle body;

[0014] The first ends of the first side rail and the second side rail are connected via a first connecting section, and the second ends of the first side rail and the second side rail are connected via a second connecting section.

[0015] Furthermore, the first connecting section and / or the second connecting section is an arc-shaped connecting section on the orthographic projection surface, and the curvature of the inner arc edge of the arc-shaped connecting section is adapted to the curvature of the outer periphery of the solder paste bottle.

[0016] Furthermore, the distance between the side of the first side rail and the second side rail facing the panel and the back plate is smaller than the distance between the bottle bottom and the side of the bottle cap facing the bottle bottom; or

[0017] The distance between the side of the first side rail and the second side rail facing the panel and the back plate is greater than the distance between the bottle bottom and the side of the bottle cap facing the bottle bottom. A convex pad is provided at a position on the back plate opposite to the inlet. The distance between the convex surface of the convex pad and the side of the first side rail and the second side rail facing the panel is less than the distance between the bottle bottom and the side of the bottle cap facing the bottle bottom.

[0018] Furthermore, the panel is a transparent or semi-transparent panel; and / or

[0019] A plurality of observation windows spaced apart from each other are provided on the panel along the length direction of the slide rail.

[0020] Furthermore, at least one mounting member is detachably provided on both lateral sides of the back panel, and the mounting member is used for sliding connection with a slide groove on the inner wall of the freezer.

[0021] In summary, the beneficial effects of the present invention are as follows: First, the solder paste bottle is loaded into the sliding channel from the inlet position, and the solder paste bottle will roll along the slide rail to the lower outlet position according to its own gravity. The solder paste bottles are loaded into the sliding channel from the inlet in order of production date. After a bottle of solder paste is taken from the outlet, the next solder paste bottle will automatically roll to the outlet. Solder paste is taken strictly according to the first-in-first-out standard to avoid wasting expired solder paste. Second, multiple storage components can be stacked according to the needs of each application scenario, occupying a small space and being able to store more solder paste; the solder paste bottles are loaded into the corresponding storage components from front to back according to the storage period of the solder paste, so that the use date of the solder paste stored in the front storage component is earlier than the use date of the solder paste in the rear storage component. Third, an anti-reverse installation structure is set at the inlet to limit the entry direction of the solder paste bottles, so that the solder paste bottles can enter the inlet in a unified direction, so that the solder paste bottles can be stored neatly and orderly, saving storage space. After the solder paste bottle is prevented from being installed upside down, each solder paste bottle can be taken out with the bottle cap facing outward at the exit, which is convenient for taking and can also save operation time for the subsequent process. Fourth, the solder paste bottle entering the slide rail, the bottle cap can be confined in the gap between the side of the track of the first track and the panel. This gap is used to limit and guide the sliding of the bottle cap, which can prevent the solder paste bottle from running off the track or getting stuck when sliding. Fifth, by setting a convex pad at the entrance to form a gap between the first side rail and / or the second side rail and the panel to limit and guide the bottle cap, the assembly of the first track and the second track can be faster and more efficient. There is no need to repeatedly confirm the distance from the first track and the second track to the back panel according to the size of the solder paste bottle. After the assembly is completed, it is only necessary to add the convex pad at the entrance according to the height of the solder paste bottle. Sixth, the translucent panel or observation window can visually observe the internal storage conditions. Seventh, the stability of the storage device is enhanced by the cooperation of the mounting parts with the slide groove in the freezer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to specific drawings.

[0030] like Figure 1 and Figure 4As shown, the present invention provides a solder paste bottle storage device that can prevent solder paste bottles from being installed upside down, and is used for storing solder paste bottles. The solder paste bottle has a cylindrical bottle body and a circular bottle cap connected to the bottle mouth of the bottle body, and the outer diameter of the bottle cap is larger than the outer diameter of the bottle body. The solder paste bottle storage device includes a storage component 100 and an anti-upside-down installation structure 600. The storage component 100 includes a back plate 110 and a sliding channel 120 provided on the back plate 110 for storing solder paste bottles. The upper end of the sliding channel 120 is provided with an inlet 121 for loading solder paste bottles, and the lower end of the sliding channel 120 is provided with an outlet 122 for taking out solder paste bottles. The solder paste bottles loaded into the sliding channel 120 can slide along the sliding channel to the outlet 122 by their own gravity to achieve first-in-first-out of the solder paste bottles. The anti-reverse loading structure 600 includes a first foolproof member 610 and a second foolproof member 620 disposed at the inlet 121. The first foolproof member 610 and the second foolproof member 620 are offset from each other along the direction in which the solder paste bottle is loaded. The first foolproof member 610 and the second foolproof member 620 are spaced apart from each other on a projection plane perpendicular to the loading direction. The space formed between the first foolproof member 610 and the second foolproof member 620 allows the bottle body to enter while preventing the bottle cap from entering. The solder paste bottles are loaded into the sliding channel 120 from the inlet 121. Since the inlet 121 is higher than the outlet 122, the cylindrical material characteristics allow the solder paste bottles to roll along the sliding channel 120 until they reach the outlet 122. This ensures that the first solder paste bottle loaded into the interior reaches the outlet 122 first. The solder paste bottles are loaded into the sliding channel 120 from the inlet 121 in the order of their production date. After one bottle of solder paste is taken from the outlet 122, the next bottle of solder paste will automatically roll to the outlet 122. Solder paste is taken strictly according to the first-in-first-out principle to avoid wasting expired solder paste. The anti-reverse loading structure 600 restricts the solder paste bottles to enter the inlet 121 in the same direction. The solder paste bottles are arranged neatly and orderly in the storage device, saving space and making them easy to access.

[0031] In the illustrated embodiment, the solder paste bottle storage device includes two groups of storage components 100, and the two groups of storage components 100 are arranged in sequence along the front-to-back direction. The panel 123 of the latter group of storage components 100 can serve as the back panel 110 of the former group of storage components 100, that is, the former group of storage components 100 and the latter group of storage components 100 can share a plate. The two groups of storage components 100 are connected into one by connecting members, and the connecting members include but are not limited to plates, strips, and columnar connecting members. Taking the plate-like structure as an example, the connecting member includes two support plates 200, and one lateral side of the back panels 110 of the two storage components 100 is connected to one of the support plates 200, and the other lateral side of the back panels 110 of the two storage components 100 is connected to the other support plate 200. Specifically, as Figure 5As shown, the two support plates 200 each have a horizontal lower bottom surface, an inner side surface 210 facing each other, an outer side surface 220 parallel to the inner side surface 210, a first upper top surface 231 of lower height, a second upper top surface 232 of higher height, a front end surface 240 connected between the first upper top surface 231 and the lower bottom surface, and a rear end surface connected between the second upper top surface 232 and the lower bottom surface. The inner side surface 210 of each support plate 200 is detachably connected to the corresponding lower end portion of the two back plates 110. The lower first upper top surface 231 and the higher second upper top surface 232 divide the support plate 200 into a first section 200a of lower height and a second section 200b of higher height along the front-to-back direction. During the assembly and connection process of the support plate 200 and the storage assembly 100, it is more convenient for a worker to hold the lower first section 200a during assembly and connection. It should be understood that although the above description uses two groups of storage components 100 as an example, it is obvious that the number of storage components of the solder paste storage device of the present application should not be limited to the above two groups. The number of storage components can be increased or decreased according to the requirements of different implementation methods, such as one group, three groups, four groups, or more groups.

[0032] After the two groups of storage components 100 are assembled together in the front-to-back direction, the inlet 121 of the latter group of storage components 100 is exposed outside the inlet 121 of the former group of storage components 100, and the outlet 122 of the latter group of storage components 100 is exposed outside the outlet 122 of the former group of storage components 100. Different storage components 100 can be used to store solder pastes of different brands or solder pastes of different production periods. The inlets 121 and outlets 122 of different storage components 100 are staggered, so they will not interfere with the loading or removal of solder paste bottles, which is more practical. Figure 1As shown, in the illustrated embodiment, an L-shaped first notch 115 is defined on the back panel 110 of the first storage assembly 100 (also the front panel 123 of the second storage assembly 100) at one end (at the upper right corner in the figure) away from the outlet 122. The inlet 121 of the first storage assembly 100 is disposed on the back panel 110 and is adjacent to the first notch 115. The inlet 121 of the second sliding channel 120 is disposed on the back panel 110 of the second storage assembly 100, directly opposite the first notch 115, such that the inlet 121 of the second storage assembly 100 is exposed outside the inlet 121 of the first storage assembly 100. An L-shaped second notch 116 is defined on the back panel 110 of the first storage assembly 100 at one end (at the lower left corner in the figure) away from the inlet 121. The outlet 122 of the first storage assembly 100 is disposed on the back panel 110 and is adjacent to the second notch 116. The back plate 110 of the latter storage assembly 100 is provided with the exit 122 of the latter sliding channel 120 opposite to the second notch 116 , so that the exit 122 of the latter storage assembly 100 is exposed outside the exit 122 of the former storage assembly 100 .

[0033] Solder paste needs to be stored at low temperatures. At least one mounting member 500 is removably provided on both lateral sides of the back panel 110. The mounting member 500 is configured to slide into a slot on the inner wall of the freezer. When the storage device is loaded with a bottle of solder paste and placed in the freezer, the mounting member 500 slides into the slot on the inner wall of the freezer. In the illustrated embodiment, vertical strip holes 111 are provided on both lateral sides of the back panel 110 at positions corresponding to the mounting member 500, distributed along the height of the back panel 110. The mounting member 500 is provided with horizontal strip holes 510 spaced apart along the height of the mounting member 500. The length of each horizontal strip hole 510 extends horizontally along the lateral direction of the mounting member 500. The horizontal strip holes 510 and the vertical strip holes 111 are screwed together by screws, allowing the mounting member 500 to be adjusted in the upper, lower, left, and right directions. The flexibly adjustable mounting member 500 can be adapted to a wider range of freezers of different sizes, making it simple and practical.

[0034] The back panel 110 of each storage assembly 100 is provided with a plurality of ventilation holes 112 extending through the back panel 110 and distributed along its height. Each ventilation hole 112 extends horizontally along the transverse direction of the back panel 110. When multiple storage assemblies 100 are connected to the support plate 200, the ventilation holes 112 facilitate ventilation of the entire storage device.

[0035] The sliding channel 120 of each storage assembly 100 includes a panel 123 disposed in front of the back panel 110 and a slide rail 124 disposed between the panel 123 and the back panel 110 and extending from front to back. The panel 123 may be transparent or translucent, and / or may be provided with a plurality of observation windows 1230 spaced apart along the length of the slide rail 124 to facilitate observation of the solder paste bottles within the storage device.

[0036] In the illustrated embodiment, the slide rail 124 and the panel 123 are connected in series along the front-to-back direction via a plurality of connecting rods spaced apart along the sliding direction, i.e., the rear end of each connecting rod can be detachably fixed to the back plate 110, and the front ends of the connecting rods are connected to the panel 123 after passing through the slide rail 124. The portion of the connecting rod that passes through the slide rail 124 is provided with a limiting portion for limiting the front-to-back displacement of the slide rail 124. The limiting portion can be defined as a small diameter segment with a smaller diameter, and the front and rear sections of the small diameter segment are both large diameter segments with a larger diameter. A perforation is provided on the slide rail 124 at a position corresponding to the small diameter segment, and the inner diameter of the perforation is smaller than that of the large diameter segment. When the small diameter segment is passed through the perforation, the two large diameter segments limit the front-to-back position of the rail 124. Specifically, the connecting rod includes a connecting rod, a first sleeve 113 arranged on a section of the connecting rod between the back plate 110 and the slide rail 124, and a second sleeve 114 arranged on a section of the connecting rod between the slide rail 124 and the panel 123. The first sleeve 113 and the second sleeve 114 can be configured as a rotatable sleeve that can rotate around the axis of the connecting rod or a non-rotatable sleeve that cannot rotate.

[0037] The orthographic projection of the slide rail 124 is serpentine, and a first end of the slide rail 124 extends beyond the panel 123, so that the first end of the slide rail 124 is not covered by the panel 123, thereby forming the entrance 121. A second end of the slide rail 124 also extends beyond the panel 123, so that the second end of the slide rail 124 is not covered by the panel 123, thereby forming the exit 122.

[0038] In the illustrated embodiment, the shape of the front panel 123 of the second storage assembly 100 matches the shape of its back panel 110. Both panels, when projected from an orthographic plane, present a rectangular plate-like structure of identical or similar dimensions, serving as the back panel 110 of the first storage assembly 100. Since the front panel 123 of the first storage assembly 100 is located at the front, with no storage devices in front of it, the orthographic shape of the front panel 123 of the first storage assembly 100 can be consistent with the orthographic shape of the corresponding slide rail 124, i.e., both exhibit a serpentine shape with overlapping front and back surfaces. This arrangement simplifies the overall structure of the solder paste storage device, reduces space usage, and makes the overall structure lighter and simpler, making it easier to observe the internal structure of the multi-layer storage device 100 and the solder paste bottles stored therein. The serpentine shape of the slide rail 124 creates a certain inclination at the contact surface between the solder paste bottles and the slide rail 124, facilitating the downward rolling of the solder paste bottles. Furthermore, the multiple curved sections facilitate storage of a larger number of solder paste bottles.

[0039] like Figure 3 As shown, the slide rail 124 includes a first rail 124a and a second rail 124b spaced apart along the front-to-back direction, with the first rail 124a and the second rail 124b facing each other in the front-to-back direction. The first rail 124a and the second rail 124b each include a first side rail 1241 and a second side rail 1242 located on the same horizontal plane. The first side rail 1241 and the second side rail 1242 are parallel to each other, and the parallel distance between them is adapted to the outer diameter of the bottle body (e.g., slightly larger than the outer diameter of the bottle body), so that the bottle body can be inserted and slidably engaged therewith. The first ends of the first side rail 1241 and the second side rail 1242 are connected by a first connecting section 1243, and the second ends of the first side rail 1241 and the second side rail 1242 are connected by a second connecting section 1244. The first connecting section 1243 and / or the second connecting section 1244 are arc-shaped connecting sections in the orthographic projection plane, and the curvature of the inner arc edge of the arc connecting section is adapted to the curvature of the outer periphery of the solder paste bottle. The distance between the first side rail 1241 and the second side rail 1242 and the curvature of the arc-shaped connecting section can be adapted to the solder paste bottle to avoid the solder paste bottle from deviating in the slide rail 124 due to excessive sliding space.

[0040] Since the outer diameter of the bottle cap is larger than the outer diameter of the bottle body, when rolling between the first side rail 1241 and the second side rail 1242, it may deviate or get stuck during rolling. The distance between the side of the first side rail 1241 and the second side rail 1242 facing the panel 123 and the back plate 110 is smaller than the distance between the bottom of the bottle and the side of the bottle cap facing the bottom of the bottle. In this embodiment, when the solder paste bottle is loaded, the bottle cap is limited to slide between the panel 123 and the side of the first track 124a. This has the advantage of guiding the solder paste bottle loaded inside to avoid deviation or getting stuck. Alternatively, the distance between the side of the first side rail 1241 and the second side rail 1242 facing the panel 123 and the back plate 110 is larger than the distance between the bottom of the bottle and the side of the bottle cap facing the bottom of the bottle. A raised pad 300 is provided on the back panel 110 directly opposite the inlet 121. The distance between the raised surface of the pad 300 and the side of the first and second side rails 1241, 1242 facing the panel 123 is shorter than the distance between the bottle bottom and the side of the bottle cap facing the bottom. A solder paste bottle inserted into the inlet 121 contacts the raised pad 300. The raised pad 300 also helps to position the bottle cap within the gap between the side of the first rail 124a and the panel 123, allowing it to slide. When the bottom of the solder paste bottle contacts the raised pad 300 and the bottle rolls on the slide rail 124, the side of the bottle cap facing the bottom contacts the side of the first and / or second side rails 1241, 1242 facing the panel 123. This helps guide the solder paste bottle and prevent it from straying or getting stuck.

[0041] The outlet 122 is provided with a blocking portion 400 for preventing the solder paste bottle from escaping from the outlet 122. The blocking portion 400 is an L-shaped structure, comprising a connecting block 410 connected to the first track 124a or the second track 124b, and a blocking block 420 connected to the front end of the connecting block 410. The blocking block 420 blocks the edge of the front end of the solder paste bottle, and a predetermined gap is formed between the rear side of the blocking block 420 (the side facing the back panel 110) and the front end of the solder paste bottle at the outlet 122. The blocking portion 420 blocks the front end of the solder paste bottle that slides into the outlet 122, preventing it from easily falling out of the outlet 122. The inner wall of the outlet 122 is provided with a cushion 1220, which can be disposed on the inner curved surface of the second connecting section 1244. The buffer pad 1220 is preferably made of silicone material, which can effectively alleviate the impact force when the solder paste bottle slides and effectively protect the solder paste bottle.

[0042] In order to facilitate the operation of the staff, so that the bottle cap of the solder paste bottle faces forward (outward) when it is taken out in the next process, so that the staff can directly take it out and unscrew the bottle cap to use the solder paste, in the embodiment shown, the anti-reverse installation structure 600 provided at the said inlet 121 can be used to prevent the solder paste bottle from being loaded upside down. The anti-reverse installation structure 600 can ensure that each solder paste bottle can only enter the said inlet 121 with the bottle bottom facing backward and the bottle cap facing forward, so that the bottle cap of each solder paste bottle in the said sliding channel 120 faces forward, which is convenient for the staff to directly unscrew the bottle cap after taking it out, without having to check whether the bottle cap is facing forward or not, saving inspection time, conforming to ergonomic principles, making it more convenient for the staff to use and improving work efficiency. In addition, all solder paste bottles are oriented in the same direction and can be tightly arranged in the sliding channel 120, solving the problem of inconsistent front and back space occupied due to different bottle cap and bottle bottom orientations, and solving the problem of large space occupied due to irregular arrangement of solder paste bottles in the sliding channel, so that the sliding channel can store more solder paste bottles.

[0043] like Figure 1 and Figure 6 As shown, in the anti-reverse installation structure 600, the first foolproofing member 610 is arranged on the side of the panel 123 close to the inlet 121, and the second foolproofing member 620 is arranged on the slide rail 124 and is arranged opposite to the first foolproofing member 610 on the orthographic projection plane. The first foolproofing member 610 and the second foolproofing member 620 are mutually offset along the direction of solder paste bottle loading, and the first foolproofing member 610 and the second foolproofing member 620 cooperate with each other to limit the solder paste bottle to maintain a uniform direction when loading into the inlet 121. Figure 2As shown, the side of the first foolproofing member 610 facing the slide rail 124 is at the same level as the inner side of the panel 123. The side of the first foolproofing member 610 facing the inlet 121 is defined as a first arc surface 611 whose diameter matches the outer diameter of the bottle cap. The side of the second foolproofing member 620 facing the first foolproofing member 610 (the side facing the inlet 121) is defined as a second arc surface 621 whose diameter matches the outer diameter of the bottle body. Preferably, on the orthographic projection plane, the first arc surface 611 and the second arc surface 621 are concentrically distributed. On the orthographic projection plane, the distance from the first arc surface 611 to the second arc surface 621 through the center of the first arc surface 611 is greater than the diameter of the second arc surface 621 (greater than the outer diameter of the bottle body) and smaller than the diameter of the first arc surface 611 (the outer diameter of the bottle cap). In this way, when the bottom of the solder paste bottle is installed in the inlet 121 with the bottom facing backward, the space between the first arc surface 611 and the second arc surface 621 can allow the bottle body to be inserted into the inlet 121 along a direction perpendicular to the front side of the back plate 110; when the bottle cap of the solder paste bottle is installed backward, since the outer diameter of the bottle cap is greater than the distance between the first arc surface 611 and the second arc surface 621, when the bottle cap moves to the anti-mock feature, the second arc surface 621 protrudes from the bottle cap toward the first arc surface 611, so the bottle cap is blocked by the second anti-mock feature 620 and cannot be further installed in the inlet 121.

[0044] With the above anti-reverse installation structure 600, the first foolproof member 610 and the second foolproof member 620 connected to the inlet 121 are formed with a distance difference in the direction perpendicular to the back plate 110 (front and back direction), such as Figure 6As shown, two virtual circles, one larger and one smaller in diameter, are extended along the inner arc edges of the first circular arc groove 611 and the second circular arc groove 621, respectively. The two virtual circles are concentrically arranged on the orthographic projection plane and are arranged one in front of the other in the front-to-back direction. The virtual circle with the larger diameter is defined as the first circle 6110 and is positioned in front. The diameter of the first circle 6110 is adapted to the outer diameter of the bottle cap, while the virtual circle with the smaller diameter is defined as the second circle 6210 and is positioned in the back. The diameter of the second circle 6210 is adapted to the outer diameter of the bottle body. If the bottle bottom is loaded backward, such loading direction is defined as forward loading. If the bottle cap is loaded backward, such loading direction is defined as reverse loading. When loading the solder paste bottle in the forward direction, since the outer diameter of the bottle body of the solder paste bottle is smaller than the outer diameter of the bottle cap and is compatible with the diameter of the second circle 6210 (slightly smaller than the diameter of the second circle 6210), the bottle body first passes through the first circle 6110 with a larger diameter, and then passes through the second circle 6210 with a smaller diameter, and can be smoothly loaded into the inlet 121. At this time, the bottle cap is located behind the panel 123 and the second foolproofing member 610. The staff can gently push the solder paste bottle into the slide rail 124 to make it roll along the slide rail 124 toward the outlet 122. When loading the solder paste bottle in the reverse direction, the bottle cap can pass through the first circle 6110 with a larger diameter, but cannot pass through the second circle 6210 with a smaller diameter. The solder paste bottle is blocked and cannot fully enter the inlet 121, which has a foolproofing effect. The solder paste bottles are loaded in the same direction to prevent reverse loading, so that the loading direction of the solder paste bottles can be controlled. The above-mentioned anti-reverse loading structure 600 has the following beneficial effects: First, the solder paste bottles in the storage device can be stored in the same direction, which is neat, beautiful, and more standardized. Second, after the solder paste bottle caps are stored forward (i.e., the bottle caps are facing the outside of the outlet), when the solder paste bottle at the outlet 122 is accessed, the staff can directly pick up the bottle caps to use it, which is more in line with people's daily living habits and reduces the feeling of awkwardness and discomfort. Third, if the solder paste is stored at low temperatures and has not yet been entered into the storage system, a further step is required to remove the solder paste bottle, apply a barcode to the solder paste bottle, and scan the solder paste into the system one by one. During the barcoding process, it is inconvenient to apply the barcode on the bottle body or bottom. Therefore, only applying the barcode on the surface of the bottle cap can facilitate the scanning operation. Therefore, if the solder paste bottle needs to be coded and entered into the system, the bottle cap should be facing the outside of the outlet 122 when the solder paste bottle is taken out. After taking out the solder paste bottle, the coding process can be started immediately without reversing the direction of the solder paste bottle, which is convenient and saves coding time. Fourth, the anti-reverse installation structure 600 is extremely simple and ingenious, effectively utilizing the front-to-back drop between the panel 123 and the slide rail 124. Only the two aforementioned curved surfaces are required to achieve the anti-reverse installation function, eliminating unnecessary, impractical structures and conserving materials. The inner arc of the first arc surface 611 matches the outer arc of the solder paste bottle cap, while the inner arc of the second arc surface 621 matches the outer arc of the solder paste bottle body, facilitating a snug and secure installation into the solder paste bottle.

[0045] The storage device operates as follows: The outer diameter of the solder paste bottle is larger than the outer diameter of the bottle cap. The anti-reverse loading structure 600 at the inlet 121 restricts the solder paste bottle from being loaded into the storage device with the bottle cap facing outward. The solder paste bottle, loaded into the slide rail 124, has its cap positioned between the first track 124a and the panel 123, limiting the position of the solder paste bottle to prevent it from rolling off course. The solder paste bottle, using its own gravity, rolls along the slide rail 124 to the outlet 122. If the solder paste bottle at outlet 122 is used, the next solder paste bottle automatically rolls to the outlet 122 and contacts the cushion 1220, mitigating the impact.

[0046] This storage device has the following beneficial effects: First, when solder paste bottles are loaded into the sliding channel 120 from the inlet 121, they roll along the slide rail 124 to the lower outlet 122 under their own gravity. The solder paste bottles are loaded into the sliding channel 120 from the inlet 121 in chronological order of their production date. After one bottle of solder paste is taken from the outlet 122, the next bottle automatically rolls to the outlet 122. Solder paste is removed strictly according to the first-in-first-out principle, avoiding the waste of expired solder paste. Second, when loading solder paste bottles, the anti-reversal loading structure 600 controls the solder paste bottles to be loaded into the sliding channel 120 in a uniform direction. Through the interaction of the first foolproofing member 610 and the second foolproofing member 620, the solder paste bottles can smoothly enter the inlet 121 when the bottle cap is facing outward. If the bottle cap is loaded in the wrong direction, the outer diameter of the bottle cap cannot fit into the second arc groove 621, and the second foolproofing member 620 prevents the bottle from entering the inlet 121, preventing the bottle from being loaded smoothly, thus achieving a foolproofing effect. Third, when the solder paste bottle enters the slide rail 124, the bottle cap can be restricted between the track side of the first track 124a and the panel 123. The gap between the track side and the panel 123 is used to limit and guide the sliding of the bottle cap, which can prevent the solder paste bottle from deviating or getting stuck when sliding.
