[0052] Embodiment one
[0053] Please refer to Figures 1 to 3 , the basic structure of the high sealing explosion-proof lamp 10 in the embodiment of the present application mainly includes the upper shell 11 and the lower shell 12 corresponding to the upper shell 11 and suitable for the upper shell 11, for brief description, the following is the designation and description of the explosion-proof lamp 10 as the high sealing explosion-proof lamp 10.
[0054] As Figure 2 shown, the cover shell edge of the lower shell 12 is provided with a clamping groove 121, and the cover shell edge of the upper shell 11 is provided with a corresponding clamping edge 111, so that the upper shell 11 can be clamped on the open end of the lower shell 12 to make the clamping groove 121 and the clamping edge 111 assembled to realize the fixation.
[0055] As Figure 3 shown, when assembled together, the edges of the upper shell 11 and the lower shell 12 abut each other, the clamping edge 111 is inserted into the clamping groove 121 to complete the limiting of the upper shell 11 and the lower shell 12, and then the upper shell 11 and the lower shell 12 are further fixed and sealed by the manufacturing process of the high sealing explosion-proof lamp 10 of the embodiment of the present application (the adhesive is arranged in the clamping groove 121 of the lower shell 12) to obtain the finished high sealing explosion-proof lamp 10.
[0056] Specifically, in the present embodiment, the lower housing 12 is mainly used for assembling electrical devices such as batteries, circuit boards, light sources, charging copper columns, etc., i.e., the main electrical components of the explosion-proof lamp 10 are all installed in the lower housing 12, and the upper housing 11 is mainly used for installing structural devices such as reflectors and lenses, etc., to achieve light reflection and dispersion, etc.
[0057] It is worth noting that the upper housing 11 and the lower housing 12 mentioned in the present application are not only referred to as "housings", but also include the components installed in the upper housing 11 and the lower housing 12, so that the upper housing 11 and the lower housing 12 can form a complete structure and a perfect function after assembly.
[0058] In order to facilitate the manufacturing process of the explosion-proof lamp 10, the bottom of the lower housing 12 in the present embodiment is provided with a positioning groove (not shown in the figure), which can be used for positioning by various processing jigs, without the need to additionally set other positioning structures to achieve positioning. The structure is simple, the actual use effect is better, and the utilization efficiency of the lower housing 12 is improved. In addition, after the assembly of the upper housing 11 and the lower housing 12 is completed, the positioning groove can be provided with a hat hook or the like to facilitate the hanging of the explosion-proof lamp 10 on a safety helmet, achieving full utilization of the positioning groove, and also preventing the accumulation of impurities and liquids due to the vacancy of the positioning groove.
[0059] The specific functions of the explosion-proof lamp 10 in the present embodiment, as well as the specific structures of the upper housing 11 and the lower housing 12 and the specific devices installed therein, are not related to the main points of the present application, so reference can be made to the related structures and functions of the explosion-proof lamp 10 commonly used in the art, which will not be described here.
[0060] Embodiment Two
[0061] Please refer to Figures 1 to 4 The manufacturing process of the high-sealing explosion-proof lamp according to the present embodiment includes the following steps:
[0062] S01: providing an upper housing and a lower housing meeting the quality standards, which can be assembled to form an explosion-proof lamp;
[0063] S02: controlling the potting machine executing the pre-selected program to pot the lower housing;
[0064] S03: detecting the potting quality of the lower housing after potting is completed, and outputting the lower housing with qualified potting quality;
[0065] S04: controlling the press to press and fix the upper housing and the lower housing with qualified potting quality, and assembling to obtain an explosion-proof lamp; and
[0066] S05: testing the sealing performance of the explosion-proof lamp, and outputting the explosion-proof lamp passing the sealing performance test as a qualified product.
[0067] The manufacturing method of the high-sealing anti-explosion lamp 10 of the present application first provides the upper shell 11 and the lower shell 12 of the anti-explosion lamp 10 meeting the quality standard, preliminarily ensures the product quality, then controls the pouring machine selected in advance to perform the pouring process on the lower shell 12, i.e. replaces the manpower with the automatic mechanical equipment to perform the pouring process, ensures the pouring effect, detects the pouring quality of the lower shell 12 after the pouring process, outputs the lower shell 12 with the qualified pouring quality, ensures the subsequent product assembly quality, then controls the press to press and fix the upper shell 11 and the lower shell 12 with the qualified pouring quality, assembles the anti-explosion lamp 10, i.e. replaces the manpower with the automatic mechanical equipment to perform the product assembly, to ensure the assembly effect, finally tests the sealing performance of the anti-explosion lamp 10, and outputs the anti-explosion lamp 10 passing the sealing performance test as the qualified product. The anti-explosion lamp 10 manufactured through the above steps has better waterproof sealing performance, higher production efficiency and yield, and better product quality, because the pouring process is used to replace the traditional sealing ring sealing process.
[0068] Specifically, in step S01, after the elements on the upper shell 11 and the lower shell 12 are installed, the inspection is needed before the sealing of the upper shell 11 and the lower shell 12, to ensure that the upper shell 11 and the lower shell 12 meet the quality standard of the product. Only the upper shell 11 and the lower shell 12 meeting the quality standard can perform the subsequent assembly process, to avoid the problem of defective products due to the quality problem of the upper shell 11 and / or the lower shell 12, to control the product quality in the first step of the manufacturing process.
[0069] More specifically, in the present embodiment, step S01 specifically includes the following steps:
[0070] S011: product quality detection and / or product function detection on the upper shell and the lower shell; and
[0071] S012: determining that the upper shell and the lower shell passing the product quality detection and the product function detection meet the quality standard.
[0072] That is to say, in the present embodiment, the detection on the upper shell 11 and the lower shell 12 includes the product quality detection and / or the product function detection. Since the elements installed in the upper shell 11 and the lower shell 12 are different, the detection on the upper shell 11 and the lower shell 12 is also slightly different. The product quality detection is needed for both the upper shell 11 and the lower shell 12, while the product function detection is mainly needed for the lower shell 12. The upper shell 11 and the lower shell 12 passing the product quality detection and the product function detection ensure that the product has normal quality and function, and can normally perform the subsequent assembly process.
[0073] Specifically, in the present embodiment, the product quality detection includes checking whether the elements on the upper shell 11 and the lower shell 12 are installed in place, whether the soldering wires of the circuit board are normal, whether there is a melting trace on the periphery after the welding of the charging copper column, and whether there is a crack in the shell, etc. These relatively external quality detections can be realized by direct observation with the naked eye. By detecting whether the quality of each component meets the standard, the product quality of the upper shell 11 and the lower shell 12 is verified.
[0074] Further, after the product quality is detected, a preliminary test of the product function is also needed. The product function test includes testing whether the light source can normally light up and whether the indicator light is normal, etc. The function detection in these aspects needs to be detected by energizing the related components, and cannot be directly detected by the naked eye. Therefore, it needs to be carried out separately from the structure detection. After confirming that the light source and the indicator light emit light without problems, the upper shell 11 and the lower shell 12 are subjected to an aging test, and after that, the upper shell 11 and the lower shell 12 can be sealed by pouring.
[0075] The above description of the product quality detection and the product function detection is only exemplary. In other embodiments, the product quality detection and the product function detection can also include more, less or different detections, which can ensure the quality of the upper shell 11 and the lower shell 12. Herein, no specific limitation is made.
[0076] In addition, the specific operation of the detection items included in the product quality detection and the product function detection should be able to be understood and operated by those skilled in the art in combination with the technology in the art and the names of the detection items. The present application does not make a detailed explanation and description here.
[0077] In the present embodiment, the sealing and fixing of the upper shell 11 and the lower shell 12 is realized by pouring and sealing the medium (such as adhesive) on the lower shell 12. In the following, the adhesive will be taken as an example to illustrate the sealing and fixing.
[0078] In step S02, in order to reduce the errors that are prone to occur in manual pouring, such as uneven pouring, too much or too little pouring, and pouring agent overflow, etc., the pouring machine is used to pour the lower bottom shell in the present embodiment. The pouring machine executes the set execution program to automatically, intelligently and accurately realize the pouring. The pouring is a common term in the art, and its specific meaning is not explained and described in detail here.
[0079] Further, in the present embodiment, step S02 specifically includes the following steps:
[0080] S021: starting the pouring machine;
[0081] S022: selecting the corresponding execution program in the pouring machine. The execution program is set in the pouring machine in advance. After determining the pouring route according to the shape of the lower shell, the programming is completed in the pouring machine.
[0082] S023: fixing the lower shell in the positioning fixture of the potting machine; and
[0083] S024: controlling the potting machine to perform potting along the clamping groove of the lower shell based on the execution program.
[0084] In the embodiment, before potting and sealing the upper shell 11 and the lower shell 12, the potting machine needs to be started and the corresponding execution program needs to be selected to control the potting machine to work. The execution program is set in the potting machine in advance and is programmed in the potting machine according to the shape of the lower shell 12 to determine the potting route, so that the potting machine can be completely adapted when potting the lower shell 12, thereby performing efficient and accurate potting along the clamping groove 121.
[0085] Then, the lower shell 12 of the product to be processed is clamped in the positioning fixture of the potting machine. The direction of the lower shell 12 of the product to be processed is positioned through the cooperation of the positioning groove at the bottom of the lower shell 12 and the convex groove on the positioning fixture, and then the potting machine is operated. At this time, the potting machine moves along the clamping groove 121 of the lower shell and performs potting, and the adhesive is injected into the clamping groove 121. In this way, when the upper shell 11 is connected with the lower shell 12, the clamping edge 111 of the upper shell 11 is inserted into the clamping groove 121 of the lower shell 12, so that the adhesive is extruded and overflowed, thereby filling the entire space of the clamping groove 121, achieving sealing and bonding.
[0086] In one embodiment, the adhesive can be AA3106, and the potting air pressure can be 0.65 MPa.
[0087] In step S03, after potting the lower shell 12, the potting quality on the lower shell 12 needs to be detected to ensure the effective bonding of the lower shell 12 and the upper shell 11, avoid affecting the assembly of the upper shell 11 and the lower shell 12 due to unqualified potting quality on the lower shell 12, and further affect the quality of the finished product.
[0088] More specifically, in the embodiment, step S03 includes the following steps:
[0089] S031: taking the lower shell after potting from the potting machine;
[0090] S032: detecting whether the potting amount on the lower shell is sufficient;
[0091] S033: if yes, determining that the potting quality of the lower shell is qualified and outputting; and
[0092] S034: if no, supplementing the potting amount on the lower shell to be sufficient and then outputting.
[0093] Specifically, after the potting of the lower shell 12 is completed by the potting machine, the processed lower shell 12 is taken out from the positioning jig of the potting machine, and the potting quality is checked. Since the amount of potting directly affects the bonding and fixing of the upper shell 11 and the lower shell 12 and the sealing effect, the detection of the potting quality mainly checks whether the amount of potting on the lower shell 12 is in place, that is, whether the amount of potting can fill the combined space of the clamping edge 111 of the upper shell 11 and the clamping groove 121 of the lower shell 12.
[0094] If the amount of potting on the lower shell 12 is sufficient, it means that the current potting quality of the lower shell 12 is qualified, and at this time, the qualified lower shell 12 is transported to the following assembly manufacturing process. If it is found that the amount of potting on the lower shell 12 is insufficient, that is, there is a lack of glue on the lower shell 12, and the adhesive may not be sufficient to completely fill the combined space of the clamping edge 111 and the clamping groove 121, manual glue supplementing is needed to make the amount of potting sufficient to achieve complete bonding and sealing.
[0095] Of course, in other embodiments, the detection of the potting quality of the lower shell 12 not only includes the detection of the amount of potting as described above, but also includes more, such as whether the potting is uniform, whether the adhesive is overflowed, the viscosity of the adhesive, and the like, so that the quality of the potting is more guaranteed, and the quality of the finished product is ensured.
[0096] In step S04, in order to reduce the error-prone situation of manual assembly of the upper shell 11 and the lower shell 12, such as uneven pressing force, excessive or insufficient pressing force, or insufficient pressing time, the pressing machine is used to assemble the upper shell 11 and the lower shell 12 in the embodiment of the application. The pressing machine can execute a set execution program to automatically, intelligently and accurately realize the pressing assembly. Pressing is a common term in the art, and its specific meaning will not be explained in detail here.
[0097] Further, in the embodiment, step S04 specifically includes the following steps:
[0098] S041: aligning the upper shell and the lower shell with qualified potting quality in the pressing machine;
[0099] S042: starting the pressing machine and setting the working parameters of the pressing machine;
[0100] S043: controlling the pressing machine to work at the working parameters, so that the upper shell and the lower shell are gradually pressed and fixed; and
[0101] S044: if there is overflow on the outer surface of the explosion-proof lamp, the overflow is removed to obtain the explosion-proof lamp.
[0102] In the embodiment, the lower shell 12 after the potting treatment can be bonded with the upper shell to form the complete explosion-proof lamp 10. Similar to the control of the potting machine, specifically, the lower shell 12 and the upper shell 11 are placed in the mold of the press bed together, so that the lower shell 12 and the upper shell 11 can be stably relative, avoiding the problems of press fixing caused by shaking or misplacement during the process of press fixing. Then, the press bed is started and the working parameters of the press bed are set, so that the press of the press bed works with the set working parameters to gradually press and fix the upper shell 11 and the lower shell 12 together. After the press of the upper shell 11 and the lower shell 12 is completed, the explosion-proof lamp 10 needs to be checked again to detect whether the explosion-proof lamp 10 has other problems, such as whether the appearance is damaged, whether the components are normal, etc., to ensure the product quality.
[0103] In addition, in order to ensure that the adhesive can fill the combination space of the clamping edge 111 of the upper shell 11 and the clamping groove 121 of the lower shell 12, the potting amount on the lower shell 12 is often more, so after the upper shell 11 and the lower shell 12 are press fixed, overflow will generally occur, that is, the adhesive will overflow from the above-mentioned combination space to the surface of the upper shell 11 and / or the lower shell 12. At this time, the overflow on the surface of the explosion-proof lamp 10 needs to be manually removed to ensure the appearance of the product and avoid sticking to other impurities or objects, etc. Of course, if the potting amount is well controlled, there is no overflow on the surface of the explosion-proof lamp 10 after the press assembly of the upper shell 11 and the lower shell 12 is completed, and then the assembled explosion-proof lamp 10 can be directly obtained.
[0104] Taking the press assembly of the explosion-proof lamp 10 in the embodiment as an example, the press can use compressed air as a power source, and the press assembly pressure is 0.14 MPa.
[0105] In the conventional process, after the press assembly of the explosion-proof lamp 10 is completed, its sealing performance needs to be detected. In step S05, the sealing performance detection includes but is not limited to air tightness detection (such as dustproof) and waterproof detection, etc. The explosion-proof lamp 10 that passes the sealing performance test is a qualified product, which has higher sealing performance than the explosion-proof lamp 10 in the prior art, can adapt to more severe application environment, and has wider application space.
[0106] The air tightness detection and waterproof detection are mature technologies in the field, and the specific detection process is not described in detail here.
[0107] In order to improve the light emitting effect of the explosion-proof lamp 10, the shell can be made of light-transmitting material, such as acrylic, transparent PC, glass, etc., that is, the upper shell 11 and the lower shell 12 are made of light-transmitting material, at this time, in addition to using a general adhesive to pot the lower shell 12, UV (Ultraviolet Rays) adhesive can also be used as the adhesive to pot the lower shell 12, and at this time, more steps are needed to assemble the upper shell 11 and the lower shell 12.
[0108] Further, in the present embodiment, the step S04 further includes the following steps:
[0109] S06: UV curing the assembled explosion-proof lamp.
[0110] It can be seen that when using UV adhesive and the like to bond, the explosion-proof lamp 10 after pressing needs to be subjected to UV curing treatment, and the adhesive can be stable after curing. Specifically, UV adhesive is a kind of adhesive that must be cured by ultraviolet light irradiation, and the curing degree is easy to control, can be repeatedly potted, and has high water resistance after curing, and is suitable for sealing the shell of the explosion-proof lamp 10 made of light-transmitting material.
[0111] Therefore, in the present embodiment, if the upper shell 11 and / or the lower shell 12 is made of light-transmitting material, the corresponding UV adhesive is used to pot the lower shell 12, so that even if there is a problem in the potting process or the pressing process, it can be corrected by repeatedly applying glue, avoiding the problem of increasing cost due to the waste of the upper shell 11 and / or the lower shell 12.
[0112] Taking the explosion-proof lamp 10 in the present embodiment as an example, the adhesive used for potting can be Loctite glue AA3106, which is a kind of ultraviolet curing adhesive with a viscosity range of 3500-7500 mPa·S. At the same time, the potting machine correspondingly uses a dark feed pipe, such as a black feed pipe, which can avoid the UV glue in the feed pipe being cured due to light irradiation, and the potting air pressure is adjusted within the range of 0.6-0.7 MPa.
[0113] Of course, even if the adhesive does not use the above-mentioned type of UV glue, as long as the adhesive is UV glue, the feed pipe of the potting machine is also dark, such as black, brown, etc., among which the black feed pipe is the best to ensure the light shielding effect, thereby effectively avoiding the UV glue being cured in advance in the transmission process due to light irradiation.
[0114] Further, in the present embodiment, the above-mentioned step S06 specifically includes the following steps:
[0115] S061: Place the explosion-proof lamp on the conveyor belt of the air-cooled UV curing oven;
[0116] S062: start the air-cooled UV curing oven and set its working parameters; and
[0117] S063: control the air-cooled UV curing oven to work at the working parameters to UV cure the explosion-proof lamp.
[0118] To improve the intelligent degree of the machine and the curing effect, in the embodiment, the UV source for curing the UV glue is an air-cooled UV curing oven, which can realize the curing of the explosion-proof lamp 10 in an intelligent and efficient manner, that is, realize the effective adhesion and fixation of the upper shell 11 and the lower shell 12, and provide air-cooling measures for cooling to ensure product safety.
[0119] Specifically, the explosion-proof lamp 10 obtained by pressing is first placed on the conveying belt of the UV curing oven, and then the UV curing oven is started and its working parameters are set. At this time, the UV curing oven works at the working parameters so that the explosion-proof lamp 10 is conveyed by the conveying belt into the UV curing oven for curing treatment, so that the upper shell 11 and the lower shell 12 are firmly connected.
[0120] If the UV glue is AA3106, the working parameters can be a curing time of 12s and a conveying speed of the conveying belt in the range of 110-130, which can effectively cure the UV glue.
[0121] Further, in the embodiment, after step S063, the following steps are further included:
[0122] S064: place the explosion-proof lamp upside down on the conveying belt of the air-cooled UV curing oven; and
[0123] S065: control the air-cooled UV curing oven to UV cure the explosion-proof lamp again after being turned over.
[0124] In addition, in order to ensure that the UV glue can be fully cured, the explosion-proof lamp 10 in the embodiment needs to pass through the UV curing oven twice, and is placed with the front and back respectively once, that is, to make the glue on the front and back be fully irradiated by UV light and be fully cured.
[0125] Therefore, after the first UV curing is completed, the explosion-proof lamp 10 is placed upside down on the conveying belt of the UV curing oven, that is, if the explosion-proof lamp 10 is placed upright after the first UV curing, that is, if the upper shell 11 is above, it is placed upside down with the upper shell 11 below for UV curing, and if the explosion-proof lamp 10 is placed upside down after the first UV curing, that is, if the upper shell 11 is below, it is placed upright with the upper shell 11 above for UV curing, to ensure the curing effect.
[0126] The automatic production line can be designed based on the manufacturing process of the high-sealing explosion-proof lamp 10 of the embodiments of the present application, and the automatic production line comprises a filling and sealing machine, a pressing machine, a forced air UV curing furnace and other devices for realizing filling and sealing, pressing and curing, and can further comprise devices for producing the upper shell 11 and the lower shell 12 at the front end, and devices for conveying qualified explosion-proof lamps 10 at the rear end, and the production system is uniformly managed to automatically realize one or more of the processes such as conveying (and detection) of the upper shell 11 and the lower shell 12, filling and sealing of the lower shell 12, pressing and fixing of the upper shell 11 and the lower shell 12, UV curing of the explosion-proof lamp 10, and sealing test of the explosion-proof lamp 10, so as to realize automatic production of the high-sealing explosion-proof lamp 10, and improve the waterproof sealing performance, production efficiency and yield of the explosion-proof lamp 10.
