Description

Technical Field

[0001] The invention relates to the technical field of combustible gas detector assembly, in particular to a combustible gas detector automatic assembly device. Background Art

[0002] A combustible gas detector is a device used to detect the concentration of combustible gas in the air. Its core component is the sensor, which mainly includes catalytic combustion type, semiconductor type and infrared type. When the detector senses that the concentration of combustible gas in the environment exceeds the preset safety value, it will immediately sound an alarm to remind the user to take corresponding safety measures; therefore, the combustible gas detector is an important device for preventing safety accidents such as fire and explosion.

[0003] The combustible gas detector has a T-shaped structure as a whole (such as Figure 8 ), which is mainly composed of a shell, a sensor, a connecting plate, etc., wherein the connecting plate is mainly used as a connector between the detector and the wall or other mounting surfaces.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1 As shown, an automatic assembly device for a combustible gas detector includes a base 1; the upper end of the base 1 is provided with a docking mechanism 2 for aligning a connecting plate with the detector and a screw assembly mechanism 3 for fixing the connecting plate to the detector.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the docking mechanism 2 includes a No. 1 support plate 20, and two front-to-back symmetrical No. 1 support plates 20 are fixedly installed on the upper end of the base 1. A No. 2 support plate 21 is fixedly installed on the right ends of the two No. 1 support plates 20. V-shaped grooves 22 are provided on the upper ends of the No. 1 support plates 20 and the No. 2 support plates 21. A support plate 23 slidably installed on the upper end of the base 1 is provided on the right side between the two No. 1 support plates 20. A No. 1 electric push rod 24 located on the left side of the support plate 23 is fixedly installed on the upper end of the base 1, and the telescopic section of the No. 1 electric push rod 24 is fixedly connected to the support plate 23.

[0035] like Figure 1 and Figure 2As shown, the support plate 23 is provided with a limiting portion 25 for limiting the connecting plate, the support plate 23 is provided with an adjusting portion 26 for adjusting the position of the limiting portion 25 to fix the connecting plate in different installation directions, the support plate 23 is also provided with a driving portion 29 for driving the limiting portion 25 to drive the connecting plate to dock with the detector, the opposite ends of the two No. 1 support plates 20 are provided with a pressing portion 28 for pressing down and fixing the detector, and a linkage portion 27 is provided between the driving portion 29 and the pressing portion 28.

[0036] During the specific operation, the detector is manually placed on the docking mechanism 2 so that the tubular section on the detector fits with the corresponding inner wall of the V-shaped groove 22. Then, the No. 1 electric push rod 24 pushes the support plate 23 to move rightward close to the detector. After the support plate 23 moves to the corresponding position, the connecting plate is straightened and fixed by the limiting part 25. Then, the driving part 29 drives the limiting part 25 and the fixed connecting plate to move downward to make the connecting plate and the detector fit together. During the downward movement of the limiting part 25, the pressing part 28 is driven to squeeze the detector from top to bottom to ensure that the detector fits with the V-shaped groove 22, so that the detector is straightened and fixed, and the stability of its subsequent installation and processing is ensured. After the connecting plate is docked with the detector, the screw assembly mechanism 3 moves to the corresponding position, and the connecting plate is installed on the detector by screws.

[0037] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the limiting portion 25 includes a U-shaped groove, and the support plate 23 is provided with a U-shaped groove. A slide seat 250 is installed in the U-shaped groove for sliding up and down. A shaft column 251 is rotatably passed through the slide seat 250. A fixing plate 252 located on the right side of the support plate 23 and having an inverted L-shaped structure is fixedly installed on the right end of the shaft column 251. Two No. 1 limiting columns 253 that cooperate with the waist-shaped groove on the vertical section of the connecting plate are symmetrically fixedly installed on the right end of the vertical section of the fixing plate 252. The horizontal section of the fixing plate 252 is provided with a shaping piece 4 for straightening the connecting plate.

[0038] like Figure 4 , Figure 5 and Figure 7As shown, the shaping member 4 includes a No. 1 slide groove, and two No. 1 slide grooves are symmetrically provided on the fixed plate 252. A No. 1 slider 40 is slidably installed in the No. 1 slide groove, and a No. 2 limiting column 41 that cooperates with the waist-shaped groove on the horizontal section of the connecting plate is slidably penetrated on the No. 1 slider 40, and a rectangular block 42 is fixedly installed on the upper end of the No. 2 limiting column 41, and a vertical plate 43 located on the left side of the rectangular block 42 is fixedly installed on the upper end of the fixed plate 252, and a roller 44 is fixedly installed on the left end of the rectangular block 42, and an inclined groove 45 corresponding to the roller 44 is provided on the right end of the vertical plate 43, and the two inclined grooves 45 are combined to form an eight-shaped structure, and a push-pull member 5 for driving the No. 2 limiting column 41 to move is provided on the fixed plate 252.

[0039] like Figure 4 and Figure 5 As shown, the push-pull member 5 includes a No. 2 electric push rod 50, the upper end of the fixed plate 252 is fixedly installed with the No. 2 electric push rod 50, the upper end of the telescopic section of the No. 2 electric push rod 50 is fixedly installed with a connecting plate 51, and the two rectangular blocks 42 are both slidably installed forward and backward at the lower end of the connecting plate 51.

[0040] During specific work, the vertical section of the connecting plate is manually fitted with the fixed plate 252, and the No. 1 limiting column 253 is passed through the waist-shaped groove on the vertical section of the connecting plate to pre-fix the connecting plate. After the connecting plate is pre-fixed by the No. 1 limiting column 253, the No. 2 electric push rod 50 pulls the connecting plate 51 to move downward, and the connecting plate 51 drives the two rectangular blocks 42 to move downward, and the rectangular blocks 42 drive the No. 2 limiting column 41 to move downward and pass through the corresponding waist-shaped groove of the horizontal section of the connecting plate. Since the rectangular block 42 cooperates with the inclined groove 45 through the roller 44, the rectangular block 42 moves downward and simultaneously moves to the side away from the No. 2 electric push rod 50 under the guidance of the inclined groove 45, until the No. 2 limiting column 41 conflicts with the arc section of the waist-shaped groove corresponding to the horizontal section of the connecting plate to align and fix the connecting plate, and then the driving unit 29 drives the aligned and fixed connecting plate to dock with the detector.

[0041] like Figure 2 and Figure 3 As shown, the driving part 29 includes a No. 3 electric push rod 290 , and the No. 3 electric push rod 290 is fixedly mounted on the left end of the support plate 23 , and the telescopic section of the No. 3 electric push rod 290 is fixedly connected to the slide seat 250 .

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the lower pressure part 28 includes a support, and a sliding tube 280 is fixedly installed on the No. 1 support plate 20 through the support. A shaft rod 281 coaxially penetrates the sliding tube 280, and a pressure plate 282 is fixedly installed on the upper end of the shaft rod 281. A guide assembly is arranged on the sliding tube 280.

[0043] like Figure 4 and Figure 6 As shown, the guide assembly includes a guide groove 283, and the annular wall of the slide tube 280 is provided with a guide groove 283, the guide groove 283 is composed of a vertical section at the bottom and an arc groove at the top surrounding the corresponding slide tube 280, and the outer wall of the shaft rod 281 is fixedly installed with a guide column 284 that slides through the corresponding guide groove 283.

[0044] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the linkage part 27 includes an inverted plate 270, the upper end of the slide seat 250 is fixedly installed with the inverted plate 270, the lower ends of the two vertical sections of the inverted plate 270 are fixedly installed with support rods 271 corresponding to the shaft rod 281 one by one, and the right end of the support rod 271 is provided with a No. 2 slide groove, and a No. 2 slider 272 is slidably installed in the No. 2 slide groove, and the lower end of the shaft rod 281 is rotatably connected with the corresponding No. 2 slider 272.

[0045] During specific operation, after the connecting plate is straightened and fixed, the No. 3 electric push rod 290 drives the fixed plate 252 to move downward through the slide 250, and the fixed plate 252 drives the connecting plate to dock and fit with the detector. In the process of the slide 250 moving downward, the inverted plate 270 will also be driven downward, and the inverted plate 270 will drive the corresponding shaft rod 281 to move downward through the support rod 271 and the No. 2 slider 272, and the shaft rod 281 drives the pressure plate 282 to rotate ninety degrees through the cooperation of the guide column 284 and the guide groove 283, so that the pressure plate 282 rotates to be directly above the detector, and then as the shaft rod 281 continues to move downward, the guide column 284 will slide down smoothly along the vertical section of the guide groove 283, so that the pressure plate 282 moves vertically downward to squeeze the detector to fix it, and then the screw assembly mechanism 3 fixes the connecting plate to the detector through screws.

[0046] After the fixation is completed, the second electric push rod 50 pushes the connecting plate 51 to move upward, and the connecting plate 51 drives the second limiting column 41 to move upward, and under the action of the inclined groove 45, the second limiting column 41 is separated from the corresponding waist-shaped groove on the connecting plate, and then the first electric push rod 24 pulls the supporting plate 23 away from the detector, and the supporting plate 23 drives the first limiting column 253 to separate from the corresponding waist-shaped groove on the connecting plate through the fixing plate 252, and the fixing plate 252 can be separated from the connecting plate so that its horizontal section does not interfere with the removal of the assembled detector, and then The rear No. 3 electric push rod 290 pushes the fixing plate 252 upward and reset through the slide 250 to fix the next connecting plate, and the upward movement of the slide 250 will push the corresponding shaft rod 281 upward through the inverted plate 270, the support rod 271 and the No. 2 slider 272. The shaft rod 281, with the cooperation of the guide column 284 and the guide groove 283, makes the pressure plate 282 move upward first and then rotate ninety degrees away from the detector to facilitate the removal of the detector installed with the connecting plate, and then repeat the above operation to continue the installation and processing of the detector.

[0047] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the adjusting portion 26 includes a T-shaped rod 260, and two T-shaped rods 260 are symmetrically arranged at the front and rear ends of the right end of the vertical section of the fixed plate 252. A limiting groove 261 corresponding to the T-shaped rod 260 is opened at the right end of the support plate 23. The horizontal section of the T-shaped rod 260 slides through the fixed plate 252 to the corresponding limiting groove 261, and a tension spring 262 is installed between the vertical section of the T-shaped rod 260 and the fixed plate 252.

[0048] like Figure 1 As shown, the screw assembly mechanism 3 includes a pillar 30, and two pillars 30 are symmetrically arranged at the upper end of the base 1. The pillars 30 are installed on the base 1 by sliding left and right through a No. 1 electric slide rail 31. The right ends of the two pillars 30 are jointly fixed with a receiving plate 32. The right end of the receiving plate 32 is slidably installed with a bottom plate 34 through a No. 2 electric slide rail 33. The right end of the bottom plate 34 is slidably installed with a mounting plate 36 through a No. 3 electric slide rail 35. The right end of the mounting plate 36 is fixed with a screw driving assembly 37. The screw driving assembly 37 is an existing mechanism and therefore will not be described in detail.

[0049] During specific operation, the T-bar 260 is manually pulled to the right to disengage the T-bar 260 from the corresponding limiting groove 261. At this time, the tension spring 262 is stretched, and then the fixed plate 252 is rotated one hundred and eighty degrees. After the rotation is completed, the T-bar 260 is released, and the T-bar 260 moves and is inserted into the corresponding limiting groove 261 under the action of the tension spring 262 to limit the range of movement of the fixed plate 252. At this time, the connecting plate is docked and fixed to the detector with the vertical section facing away from the detector.

[0050] After the detector is fixed, the connecting plate is straightened and fixed and docked with the detector, the left and right position of the screw assembly 37 is adjusted by the No. 1 electric slide rail 31, and the front and rear position of the screw assembly 37 is adjusted by the No. 2 electric slide rail 33. The screw assembly 37 is then driven by the No. 3 electric slide rail 35 to approach the position where the screws need to be installed, and then the screw assembly 37 fixes the connecting plate to the detector through the knob screw.
