Description

Technical Field

[0001] This application relates to the field of housing assembly technology, and more specifically to an automatic snap-fit ​​housing assembly mechanism. Background Technology

[0002] Smoke detectors are of practical significance in preventing fires and reducing fire losses, and are currently widely used in homes, public buildings and other fields.

[0003] The smoke alarm's outer casing consists of two shells, an upper shell and an lower shell. During the production and assembly process of the smoke alarm, workers first install the electronic components in the lower shell 01, and then assemble the lower shell 01 with the upper shell 03 using equipment or manually. In this process, the existing assembly equipment has difficulty accurately positioning the clips 04 and the inserts 05 between the slots 02 and the insertion holes, which affects the assembly between the lower shell 01 and the upper shell 03. Furthermore, the misalignment between the two shells may cause the inserts 05 to damage the lower shell 01 or break. If the assembly is done manually, workers need to align the shells back and forth, which increases the workload of the workers and affects the assembly efficiency between the shells 01 and the upper shell 03.

[0004] Meanwhile, during the assembly of the housing, due to the loose or unsecured wires of the electronic components inside the lower housing 01, the wires on the electronic components inside the lower housing 01 may fall onto the upper surface of the lower housing 01 or be close to the inner edge of the lower housing 01 under gravity or vibration. If this is not addressed, it will affect the installation between the lower housing 01 and the upper housing 03, and will also cause the wires close to the inner edge of the lower housing 01 to be easily crushed by the upper housing 03 during installation.

[0010] Furthermore, it is particularly preferred that a ball bead is rotatably connected to the sensor head.

[0011] Furthermore, it is particularly preferred that a second spring is fixedly connected to the first fixing rod, and one end of the second spring is fixedly connected to the first connecting plate.

[0012] Furthermore, it is particularly preferred that the bracket is equipped with an adjusting rod, which allows the lower housing to be centered on the conveyor belt, and a motor is fixedly connected to the clamping mechanism, with the motor output shaft rotatably connected to the first fixed plate.

[0013] Furthermore, it is particularly preferred that the clamping mechanism includes a first support plate fixedly connected to the bracket, a placement plate for placing the upper housing is mounted on the first support plate, a robotic arm is fixedly connected to the first support plate, a U-shaped plate is fixedly connected to the robotic arm, a three-jaw chuck is fixedly connected to the U-shaped plate, a second connecting plate is fixedly connected to the three-jaw chuck, the second connecting plate is rotatably connected to a second rotating roller, and the second connecting plate is rotatably connected to a first fixed plate.

[0014] Furthermore, it is particularly preferred that the pushing mechanism includes a second electric push rod fixedly connected to the bracket, a second fixed plate fixedly connected to the telescopic part of the second electric push rod, the second fixed plate being slidably connected to the connecting rod, the second fixed plate being fixedly connected to one end of the first spring, and an arc-shaped plate fixedly connected to the second fixed plate, the arc-shaped plate being rotatably connected to the first rotating roller.

[0015] Furthermore, it is particularly preferred that a fixing ring is fixedly connected to the three-jaw chuck, a plurality of third electric push rods are fixedly connected to the fixing ring, a T-shaped plate is fixedly connected to the telescopic part of the third electric push rod, a second fixing rod is slidably connected to the T-shaped plate, a third spring is provided on the second fixing rod, the third spring is fixedly connected to the T-shaped plate, a push plate connected to the third spring is fixedly connected to the second fixing rod, a sensing column is fixedly connected to the second fixing rod, and a sensing plate is fixedly connected to the T-shaped plate.

[0016] Furthermore, it is particularly preferred that a second support plate is fixedly connected to the bracket, a first electric slide rail is fixedly connected to the second support plate, a first electric slider is slidably connected to the first electric slide rail, a U-shaped seat is fixedly connected to the first electric slider, a second electric slide rail is fixedly connected to the U-shaped seat, a second electric slider is slidably connected to the second electric slide rail, a third connecting plate is fixedly connected to the second electric slide rail, an annular tube is fixedly connected to the third connecting plate, multiple elastic telescopic tubes are provided on the annular tube, a third fixing plate is fixedly connected to the telescopic part of the elastic telescopic tube, a torsion spring rod is rotatably connected to the third fixing plate, and a lever is fixedly connected to the torsion spring rod.

[0017] In addition, it is particularly preferable that the lower side of the lever is made into a curved surface to prevent the lever from scratching the surface of the lower housing when it moves.

[0018] The advantages of the automatic snap-fit ​​housing assembly mechanism described in this application are:

[0019] A. This invention, through the cooperation of the connecting rod, the first spring, the sensing head, the ball, and the first rotating roller, enables the lower housing to be positioned quickly and accurately. Simultaneously, through the cooperation of the first fixing rod, the sensing plate, the second spring, and the second rotating roller, the upper housing can be positioned quickly and accurately. This ensures that the slot on the lower housing and the buckle on the upper housing are in a directly opposite position, facilitating rapid assembly between the lower and upper housings. It also solves the problem in existing assembly equipment where the buckles and inserts are difficult to precisely position between the slots and inserts, affecting the assembly of the lower and upper housings. Furthermore, misalignment can lead to damage to the lower housing by the inserts or even breakage. Manual assembly requires workers to repeatedly align the inserts, increasing their workload and reducing assembly efficiency.

[0020] B. The present invention also involves the following: when the insert is not broken, as the push plate moves, the insert will contact the push plate and force the push plate to move forward. The second fixing rod and the sensing post move synchronously with the push plate. The third spring is compressed, so that the moving sensing post will contact the round hole on the sensing plate. The sensing plate will then react, indicating that the insert is not broken. If the sensing plate does not react, it indicates that the insert is broken or has a problem with instability.

[0021] By conducting the aforementioned inspection of the insertion post, the lack of inspection of the insertion post during the assembly of the lower and upper shells, as is present in the prior art, is avoided. This would prevent the stability of the assembled lower and upper shells from being affected if the insertion post is broken.

[0022] C. The present invention also uses a movable lever to push the wires on the upper surface of the lower housing or adjacent to the inner edge of the lower housing, so that the pushed wires fall into the lower housing. This avoids the situation where the wires of electronic components fall on the upper surface of the lower housing or adjacent to the inner edge of the lower housing, which would affect the installation between the lower and upper housings if not treated. At the same time, it would also cause the wires adjacent to the inner edge of the lower housing to be easily crushed by the upper housing during installation.

[0023] D. The present invention also involves the following: as the lever continues to move, the lever will disengage from the upper surface of the lower housing, and the torsion spring rod will change from a torsional state to a normal state. During the change of the torsion spring rod, the lever will be deflected, causing the lever to change from an inclined state to a vertical state. In this process, the lever will exert a downward pressing tendency on the line, allowing the line to be better pressed into the lower housing. This avoids the situation where, if the line is directly pushed into the lower housing, it is still located at the edge of the lower housing. Consequently, after the lever returns to its original position, there is a lack of resistance for the line, and the line has a slight rebound force, which may cause the line to droop back onto the upper surface of the lower housing under the action of the rebound force.

[0042] Example 1

[0043] Automatic snap-fit ​​housing assembly mechanism, such as Figure 1-8 As shown, it includes a support frame 1 and a conveyor belt 2, with the conveyor belt 2 mounted on the support frame 1;

[0044] A pushing mechanism is connected to the bracket 1, a connecting rod 4 is slidably connected to the pushing mechanism, a first spring 5 is fixed to the connecting rod 4, a sensing head 6 is fixed to the connecting rod 4, a first rotating roller 8 that acts on the lower housing 01 is rotatably connected to the pushing mechanism, and the pushing mechanism can drive the connecting rod 4 and the parts connected to it to move back and forth.

[0045] A clamping mechanism is connected to the bracket 1. The clamping mechanism can clamp and move the upper housing 03. A second rotating roller 9 is rotatably connected to the clamping mechanism. A first fixed plate 10 is provided on the clamping mechanism. A first electric push rod 11 is fixedly connected to the first fixed plate 10. A first connecting plate 12 is fixedly connected to the telescopic part of the first electric push rod 11. A first fixed rod 13 is slidably connected to the first connecting plate 12. A sensing plate 14 is installed and fixedly connected to the first fixed rod 13.

[0046] The sensor head 6 is designed as a flat-topped pyramid, which allows the sensor head 6 to be better inserted into the card slot hole 02.

[0047] A ball 7 is rotatably connected to the sensor head 6.

[0048] A second spring 15 is fixedly connected to the first fixing rod 13, and one end of the second spring 15 is fixedly connected to the first connecting plate 12.

[0049] The bracket 1 is equipped with an adjusting rod 3, which enables the lower housing 01 to be centered on the conveyor belt 2. A motor 16 is fixedly connected to the clamping mechanism, and the output shaft of the motor 16 is rotatably connected to the first fixed plate 10.

[0050] The clamping mechanism includes a first support plate 21 fixedly connected to the bracket 1. A placement plate 22 for placing the upper housing 03 is installed on the first support plate 21. A robotic arm 23 is fixedly connected to the first support plate 21. A U-shaped plate 24 is fixedly connected to the robotic arm 23. A three-jaw chuck 25 is fixedly connected to the U-shaped plate 24. A second connecting plate 26 is fixedly connected to the three-jaw chuck 25. The second connecting plate 26 is rotatably connected to the second rotating roller 9 and rotatably connected to the first fixed plate 10.

[0051] The pushing mechanism includes a second electric push rod 31 fixedly connected to the bracket 1. A second fixed plate 32 is fixedly connected to the telescopic part of the second electric push rod 31. The second fixed plate 32 is slidably connected to the connecting rod 4. The second fixed plate 32 is fixedly connected to one end of the first spring 5. An arc-shaped plate 33 is fixedly connected to the second fixed plate 32. The arc-shaped plate 33 is rotatably connected to the first rotating roller 8.

[0052] When using this automatic snap-fit ​​housing assembly mechanism, firstly, the operator places the upper housing 03 on the placement tray 22 in advance. Then, the lower housing 01 with the electronic components installed is placed on the left end of the conveyor belt 2. At this time, the adjustment rod 3 is set so that the lower housing 01 can be in the center position on the conveyor belt 2, which facilitates the subsequent clamping and positioning of the lower housing 01.

[0053] Next, the control conveyor belt 2 moves the lower housing 01 to the right between the two arc-shaped plates 33. At this point, the control conveyor belt 2 stops working, and then the control second electric push rod 31 causes the two second fixed plates 32 to move towards each other. The corresponding arc-shaped plates 33, the first rotating rollers 8, the connecting rods 4, and the parts connected to them will move synchronously with the second fixed plates 32. Then, the four first rotating rollers 8 will contact the housing 01 and clamp the housing 01. At the same time, since the direction of the slot holes 02 on the lower housing 01 is uncertain, during the movement of the connecting rod 4... When the connecting rod 4 is misaligned with the slot hole 02, the ball 7 will contact the lower housing 01 and push the ball 7 to move towards the second fixed plate 32. The connecting rod 4 and the sensing head 6 move synchronously with the ball 7. The first spring 5 is stretched. Then, the first rotating roller 8 is controlled to rotate, and the first rotating roller 8 will drive the lower housing 01 to rotate. During this process, the ball 7 will roll on the sensing head 6. By setting the ball 7 to roll, the friction between the ball 7 and the lower housing 01 is reduced, thereby avoiding excessive friction that would cause the outer surface of the lower housing 01 to be scratched.

[0054] Then, when the slot hole 02 on the rotating lower housing 01 is located at the ball 7, the first spring 5 changes from the stretched state to the normal state. During the change of the first spring 5, the first spring 5 will drive the connecting rod 4 to slide on the second fixed plate 32. The sensing head 6 and the ball 7 move synchronously with the connecting rod 4. Then the sensing head 6, the ball 7 and the end of the connecting rod 4 will enter the slot hole 02. At this time, the sensing head 6 located in the slot hole 02 will make a sensing, and thus control the first rotating roller 8 to stop rotating through the signal transmission of the sensing head 6. In this way, the precise positioning of the lower housing 01 is completed, which facilitates the precise assembly between the lower housing 01 and the upper housing 03 in the future.

[0055] Meanwhile, during the aforementioned positioning of the lower housing 01, using a top-down view as a reference, the robotic arm 23 is controlled to rotate the U-shaped plate 24 and its connected parts counterclockwise by 90 degrees, so that the three-jaw chuck 25 is positioned directly above the placement tray 22. Next, the robotic arm 23 is controlled to move the U-shaped plate 24 downwards, so that the upper housing 03 on the placement tray 22 is positioned between the three second rotating rollers 9. Then, the three-jaw chuck 25 is controlled to move the three second connecting plates 26 towards each other. The second rotating rollers 9, the first fixed plate 10, and their connected parts move synchronously with the second connecting plates 26, so that the second rotating rollers 9 contact the upper housing 03 and clamp it. Then, the robotic arm 23 is controlled to move the U-shaped plate 24 upwards to reset. Next, the robotic arm 23 is controlled to rotate the U-shaped plate 24 and its connected parts clockwise by 90 degrees to reset. During this process, the first electric push rod 1 is simultaneously controlled. 1. Move the first connecting plate 12 backward. The first fixing rod 13, the sensing plate 14, and the second spring 15 move synchronously with the first connecting plate 12. Since the two buckles 04 on the upper housing 03 are not in a fixed direction, when the buckles 04 and the first fixing rod 13 are misaligned, the first fixing rod 13 will not contact the buckles 04 as it moves backward. Taking the top-down view as a reference, control the second rotating roller 9 to drive the upper housing 03 to rotate counterclockwise. The buckles 04 and the insert 05 rotate synchronously with the upper housing 03. During this process, since the buckles 04 are longer than the insert 05, the insert 05 will not contact the first fixing rod 13. Then, when the rotating buckles 04 contact the sensing plate 14, the sensing plate 14 will sense the signal. Through the signal transmission of the sensing plate 14, control the second rotating roller 9 to stop rotating. In this way, the precise positioning of the upper housing 03 is completed.

[0056] This explains that when the latch 04 and the first fixing rod 13 are in a relative position, as the first fixing rod 13 moves backward, the latch 04 will contact the first fixing rod 13 and force the first fixing rod 13 to slide forward on the first connecting plate 12. The second spring 15 is compressed. Taking the top-down view as a reference, the second rotating roller 9 is then controlled to drive the upper housing 03 to rotate counterclockwise. As a result, the latch 04 will disengage from the first fixing rod 13, and the second spring 15 will change from a compressed state to a normal state. During the change of the second spring 15, the first fixing rod 13 will slide backward on the first connecting plate 12 to reset. Thus, through the setting of the second spring 15, the first fixing rod 13 can be reset in time after it moves forward and disengages from the latch 04, thereby avoiding the sensor 14 from affecting the positioning of the upper housing 03.

[0057] After the upper housing 03 is positioned, the motor 16 is controlled to rotate the first fixing plate 10 counterclockwise by 90 degrees, based on the front-to-back view. The first electric push rod 11 and the parts connected to it rotate synchronously with the first fixing plate 10, thereby avoiding the second electric push rod 31 from easily limiting the first fixing plate 10 when the lower housing 01 is assembled with the upper housing 03, thus affecting the assembly between the lower housing 01 and the upper housing 03.

[0058] Next, the robotic arm 23 is controlled to move the U-shaped plate 24 downward. The upper housing 03, the three-jaw chuck 25, and the parts connected to it move downward synchronously with the U-shaped plate 24. During this process, since the insertion post 05 is in a position directly opposite to the insertion hole on the lower housing 01, and the buckle 04 is also in a position directly opposite to the slot hole 02, the buckle 04 and the insertion post 05 will be precisely inserted into the slot hole 02 and the insertion hole on the lower housing 01, thus completing the assembly between the lower housing 01 and the upper housing 03.

[0059] Thus, through the cooperation of the connecting rod 4, the first spring 5, the sensing head 6, the ball 7, and the first rotating roller 8, the lower housing 01 can be positioned quickly and accurately. At the same time, through the cooperation of the first fixing rod 13, the sensing plate 14, the second spring 15, and the second rotating roller 9, the upper housing 03 can be positioned quickly and accurately. This ensures that the slot hole 02 on the lower housing 01 and the buckle 04 on the upper housing 03 are in a directly opposite position, facilitating the rapid assembly of the lower housing 01 and the upper housing 03. This solves the problem in the prior art where, during assembly, the buckle 04 and the insert 05 are difficult to accurately position between the slot hole 02 and the insert hole, thus affecting the assembly of the lower housing 01 and the upper housing 03. Furthermore, misalignment between the two can cause the insert 05 to damage the lower housing 01 or break. If assembled manually, workers need to align the parts repeatedly, increasing their workload and affecting the assembly efficiency of the lower housing 01 and the upper housing 03.

[0060] Example 2

[0061] Based on Example 1, such as Figure 7-8 As shown, a fixed ring 41 is fixedly connected to the three-jaw chuck 25, and multiple third electric push rods 42 are fixedly connected to the fixed ring 41. A T-shaped plate 43 is fixedly connected to the telescopic part of the third electric push rod 42. A second fixed rod 44 is slidably connected to the T-shaped plate 43. A third spring 45 is provided on the second fixed rod 44. The third spring 45 is fixedly connected to the T-shaped plate 43. A push plate (46) connected to the third spring 45 is fixedly connected to the second fixed rod 44. A sensing column 47 is fixedly connected to the second fixed rod 44. A sensing plate 48 is fixedly connected to the T-shaped plate 43.

[0062] Here it is explained that after the upper housing 03 is positioned, the third electric push rod 42 is controlled to move the T-shaped plate 43 toward the insertion post 05. The second fixing rod 44, the third spring 45, the push plate 46, the sensing post 47, and the sensing plate 48 move synchronously with the T-shaped plate 43. During this process, due to the compression or collision between the upper housing 03 during transportation or handling, the insertion post 05 may break. When the insertion post 05 is not broken, as the push plate 46 moves, the insertion post 05 will contact the push plate 46 and force the push plate 46 to move forward. The second fixing rod 44 and the sensing post 47 move synchronously with the push plate 46. The third spring 45 is compressed, so the moving sensing post 47 will contact the round hole on the sensing plate 48. The sensing plate 48 will sense this, which indicates that the insertion post 05 is not broken. If the sensing plate 48 does not sense this, it indicates that the insertion post 05 is broken or has a problem with instability.

[0063] By inspecting the insert 05 as described above, the lack of inspection of the insert 05 during the assembly of the lower housing 01 and the upper housing 03 in the prior art is avoided, which would affect the stability of the assembled lower housing 01 and upper housing 03 if the insert 05 is broken.

[0064] Example 3

[0065] Based on Example 2, such as Figure 9-10 As shown,

[0066] A second support plate 51 is fixedly connected to the bracket 1. A first electric slide rail 52 is fixedly connected to the second support plate 51. A first electric slider 53 is slidably connected to the first electric slide rail 52. A U-shaped seat 54 is fixedly connected to the first electric slider 53. A second electric slide rail 55 is fixedly connected to the U-shaped seat 54. A second electric slider 56 is slidably connected to the second electric slide rail 55. A third connecting plate 57 is fixedly connected to the second electric slide rail 55. An annular tube 58 is fixedly connected to the third connecting plate 57. Multiple elastic telescopic tubes 59 are provided on the annular tube 58. A third fixing plate is fixedly connected to the telescopic part of the elastic telescopic tube 59. A torsion spring rod is rotatably connected to the third fixing plate. A lever is fixedly connected to the torsion spring rod.

[0067] The lower side of the lever is designed with an arc surface to prevent the lever from scratching the surface of the lower housing 01 when it is moved.

[0068] Here, it is explained that the air inlet of the annular tube 58 is connected to the external pump. Next, after the lower housing 01 is positioned as described above, the first electric slide rail 52 is controlled to move the first electric slider 53 to the left. The U-shaped seat 54 and its connected parts will move synchronously with the first electric slider 53, thus positioning the annular tube 58 directly above the lower housing 01. Then, the second electric slide rail 55 is controlled to move the second electric slider 56 downwards. The third connecting plate 57 and its connected parts will move synchronously with the second electric slider 56, thus positioning the lever plate on the outer ring surface of the lower housing 01, with its lower side slightly lower than the upper surface of the lower housing 01. Next, the external pump is controlled to supply air into the annular tube 58, which then enters the elastic telescopic tube 59, forcing its telescopic portion to extend. The third fixing plate, torsion spring rod, and lever plate will move synchronously with the telescopic portion of the elastic telescopic tube 59. During this process, the lever plate will contact the lower housing 01. This will force the lever to rotate the torsion spring rod on the third fixed plate. The torsion spring rod will twist, and the lever will change from a vertical state to an inclined state. Then, the inclined lever will contact the upper surface of the lower housing 01 and move along the upper surface of the lower housing 01. During this process, due to the loose or unsecured wires of the electronic components inside the lower housing 01, the wires on the electronic components inside the lower housing 01 will fall onto the upper surface of the lower housing 01 or the inner edge of the lower housing 01 under gravity or vibration. The moving lever will then push the wires on the upper surface of the lower housing 01 or the inner edge of the lower housing 01, so that the pushed wires fall into the lower housing 01. This avoids the situation where the wires of the electronic components fall onto the upper surface of the lower housing 01 or the inner edge of the lower housing 01. If this is not handled, it will affect the installation between the lower housing 01 and the upper housing 03. At the same time, it will also cause the wires near the inner edge of the lower housing 01 to be easily crushed by the upper housing 03 during installation.

[0069] Then, after the lever pushes the line into the lower housing 01, as the lever continues to move, it will disengage from the upper surface of the lower housing 01. The torsion spring rod will change from a torsional state to a normal state. During the change of the torsion spring rod, the lever will be deflected, causing the lever to change from an inclined state to a vertical state. In this process, the lever will exert a downward pressing force on the line, allowing the line to be better pressed into the lower housing 01. This avoids the situation where, if the line is directly pushed into the lower housing 01, it will still be located at the edge of the lower housing 01. After the lever returns to its original position, due to the lack of resistance to the line and the slight rebound force of the line, the line may droop back onto the upper surface of the lower housing 01 under the action of the rebound force.

[0070] Next, to prevent the annular tube 58 from limiting the upper housing 03 during downward movement, the second electric slide rail 55 is controlled to move the second electric slider 56 upward to reset, and then the first electric slide rail 52 is controlled to move the first electric slider 53 to the left to reset.

[0071] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0072] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
