Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automated constant flow valve assembly machine and its assembly method. Background Technology

[0002] As a portable ignition device, the core function of a lighter relies on the stability of its gas supply system. A traditional lighter typically consists of a body, a fuel storage chamber, and a valve assembly, where the valve uses a constant flow valve structure to control the release of gas.

[0003] As per the instruction manual Figure 1 As shown, the constant flow valve mainly consists of a valve body 13, a breathable membrane 14, and a pressure diaphragm 15. The gas flow rate is regulated by the dynamic compression of the breathable membrane by the pressure diaphragm. Currently, the assembly of the constant flow valve mainly relies on manual operation or semi-automatic equipment.

[0004] Manual assembly is slow and cumbersome, making it difficult to adapt to the pace of modern large-scale production. Meanwhile, semi-automated production lines lack effective connection mechanisms between workstations. Key processes such as valve body positioning, diaphragm bonding, and pressure calibration require multiple manual interventions, which is detrimental to the automation development of the industry. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as slow manual assembly speed and lack of effective connection mechanisms between workstations in semi-automated production lines, and to propose an automated constant flow valve assembly machine and its assembly method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an automated constant flow valve assembly machine, including:

[0008] The machine base and the turntable rotatably connected to the machine base, with several jigs for supporting the valve body distributed around the upper circumference of the turntable;

[0009] The machine base is also equipped with a valve body feeding mechanism, a valve body detection mechanism, a film loading mechanism, a film detection mechanism, a copper sheet loading mechanism, a copper sheet detection mechanism, a riveting mechanism, a feeding mechanism, and a fixture detection mechanism, all of which are installed around the outside of the turntable.

[0010] A dust removal station is reserved between the valve body detection mechanism and the film loading mechanism.

[0011] Furthermore, the valve body feeding mechanism includes:

[0012] A valve body vibratory plate is installed on the side of the machine and a linear vibratory guide rail is installed on the top of the machine. A frame is also fixedly installed on the top of the machine. A material distribution plate and a sliding plate driven by a material distribution cylinder are fixedly installed inside the frame. The material distribution plate has a slide rail opposite to the linear vibratory guide rail. A groove is opened on the side of the sliding plate facing the end of the slide rail.

[0013] Furthermore, the valve body feeding mechanism also includes;

[0014] The upper slide plate is slidably connected in the frame one. A transverse cylinder that drives the upper slide plate to move laterally is fixedly installed on the side of the frame one. The front end of the upper slide plate is slidably connected to the carrier plate. Two clamping parts are installed on the front end of the carrier plate. A longitudinal cylinder that drives the carrier plate to move up and down is fixedly installed on the upper end of the upper slide plate.

[0015] Furthermore, the valve body detection mechanism includes a column fixed on the machine base, and a guide plate is installed on the upper end of the column via a detection cylinder that can be raised and lowered.

[0016] Two spring probe assemblies are mounted on the end face of the guide plate, and a sensor for detecting the position of the probe in the spring probe assembly is also fixedly mounted on the upper side of the guide plate.

[0017] Furthermore, the film loading mechanism includes a base plate and a top plate slidably connected to the base plate, and a push cylinder for driving the top plate to move laterally is installed on the base plate;

[0018] The top plate is equipped with an unwinding assembly and a winding assembly for unwinding and rewinding film rolls. The bottom plate is also equipped with a film punching assembly. A film suction plate is driven to move by a film suction cylinder above the bottom plate. A suction head is fixedly installed on the end face of the film suction plate. The suction head is opposite to the valve body mounting hole on the fixture.

[0019] Furthermore, the film punching assembly includes a second column fixed on the base plate, a support plate fixedly installed above the second column, a film punching mounting plate slidably driven by a film punching cylinder at the front end of the support plate, two film punching heads fixedly installed at the front end of the film punching mounting plate, and a film clamping plate with a perforation fixedly installed in front of the support plate, the film roll passing through the perforation, and a through hole opposite to the film punching head opened on the film clamping plate.

[0020] Furthermore, the riveting mechanism includes two frames fixed on the machine base. An adjusting seat is slidably driven by a riveting cylinder at the front end of the frame two. A riveting head is fixedly installed at the bottom of the adjusting seat. A stamping plate is also installed at the bottom of the frame two. A stamping cylinder that drives the stamping plate to move laterally is fixed on the outside of the frame two.

[0021] Furthermore, the feeding mechanism includes a frame three mounted on the machine base, with two feeding hoppers fixedly installed inside the frame three, and a distributing hopper inside the frame three driven to rotate by a motor;

[0022] A feeding plate slides laterally inside the frame three. The front end of the feeding plate is slidably connected to a clamping plate. Two pneumatic grippers are fixedly installed at the front end of the clamping plate. A feeding cylinder one is fixedly installed on the top of the frame three to drive the feeding plate to move laterally. A feeding cylinder two is fixedly installed above the feeding plate to drive the clamping plate to move up and down.

[0023] Furthermore, the membrane detection mechanism, copper sheet detection mechanism, and fixture detection mechanism have the same structure, and the copper sheet loading mechanism and the valve body feeding mechanism have the same structure.

[0024] The membrane detection mechanism includes a column three and a mounting base fixed on the column three, with a sensor two fixed above the mounting base.

[0025] Furthermore, this invention also proposes an automated constant flow valve assembly method, which uses the aforementioned assembly machine. This method specifically includes the following steps:

[0026] In step S100, multiple fixtures are rotated circumferentially by a turntable;

[0027] In step S200, each fixture first enters the area below the valve body loading mechanism to load the valve body. After loading, it continues to rotate to the area below the valve body detection mechanism to perform forward and reverse detection of the valve body.

[0028] In step S300, the fixture continues to rotate to the bottom of the membrane loading mechanism to fill the constant current membrane. After the filling is completed, the installation status of the constant current membrane is detected by the membrane detection mechanism.

[0029] In step S400, the fixture continues to rotate to the bottom of the copper sheet loading mechanism to load copper sheets, with the copper sheets covering the constant current membrane. Similarly, after the copper sheets are installed, the fixture rotates to the bottom of the copper sheet detection mechanism to detect the copper sheets.

[0030] In step S500, the fixture continues to rotate to the bottom of the riveting mechanism so that the valve body can limit and lock the copper sheet by punching the end of the valve body. At this time, the valve body assembly is completed. The forming part can be unloaded by the unloading mechanism during subsequent rotation.

[0031] In step S600, the fixture with the finished material is placed under the fixture inspection mechanism for part inspection. Once the part in the current fixture has been finished, the above steps can be repeated to achieve continuous assembly of the valve body.

[0032] The present invention proposes an automated constant flow valve assembly machine and its assembly method, which has the following advantages: The assembly machine of the present invention is used to realize the automated continuous assembly of the constant flow valve body, constant flow diaphragm and copper sheet, thereby improving the overall production efficiency of the constant flow valve.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Reference Figure 2-16 As one embodiment of the present invention, an automated constant flow valve assembly machine is disclosed. This assembly machine is used to realize the automated continuous assembly of the constant flow valve body, constant flow diaphragm and copper sheet, thereby improving the overall production efficiency of the constant flow valve.

[0052] Reference Figure 3 , Figure 4 Specifically, the assembly machine includes a machine base 1 and a turntable 2 rotatably connected to the machine base 1. In this embodiment, the turntable 2 is driven by a servo motor or intermittent divider, etc. The specific driving method is conventional for those skilled in the art and will not be elaborated upon here. Furthermore, as... Figure 2As shown, in this embodiment, a frame is also installed above the machine base 1. The frame is equipped with an opening and closing door and an observation window, which is used to isolate and protect the various mechanisms during the assembly of the constant flow valve, thereby improving the safety of the operation. Several jigs 20 for supporting the valve body are distributed around the upper circumference of the turntable 2. In this embodiment, the jig 20 is a plate. Two valve body mounting holes are opened on the end face of the jig 20. The valve body mounting holes are stepped through holes. The stepped through holes adopt a structure design that is larger at the top and smaller at the bottom. The valve body is inserted into the upper side of the stepped hole. The lower side of the stepped hole is for connecting negative pressure to achieve suction and traction of the constant flow membrane when installing the constant flow membrane later.

[0053] Reference Figure 4 The machine base 1 is also equipped with a valve body feeding mechanism 3, a valve body detection mechanism 4, a film loading mechanism 5, a film detection mechanism 6, a copper sheet loading mechanism 7, a copper sheet detection mechanism 8, a riveting mechanism 9, a feeding mechanism 10, and a fixture detection mechanism 11, which surround the outside of the turntable 2.

[0054] A dust removal station 12 is reserved between the valve body detection mechanism 4 and the film loading mechanism 5. Specifically, the dust removal station 12 in this embodiment is used to remove dust from the valve body. In this embodiment, an air blowing pipe can be installed on the machine base 1 to achieve dust removal by air blowing. The air blowing pipe blows air downward along the upper side of the valve body to ensure the cleanliness of the valve body.

[0055] Reference Figure 5 , Figure 6 In some embodiments, the valve body feeding mechanism 3 of the present invention includes:

[0056] The valve body vibrating plate 31 is installed on the side of the machine base 1 and the linear vibration guide rail 32 is installed on the top of the machine base 1. The linear vibration guide rail 32 is installed at the tail end of the discharge port of the valve body vibrating plate 31. The valve body vibrating plate 31 is designed to sort and distribute the valve bodies to ensure that the valve bodies can enter the linear vibration guide rail 32 in a predetermined regular posture.

[0057] A frame 33 is fixedly installed above the machine base 1. A material distribution plate 34 and a sliding plate 35 driven by a material distribution cylinder 30 are fixedly installed inside the frame 33. Specifically, in this embodiment, the material distribution cylinder 30 is fixed to one side of the frame 33, and its shaft end is connected to the sliding plate 35. The material distribution plate 34 has a slide rail opposite to the linear vibration guide rail 32. The side of the sliding plate 35 is provided with a groove 351 facing the tail end of the slide rail.

[0058] When feeding the valve body, the valve body is held in a predetermined posture by the valve body vibrating plate 31 and enters the linear vibrating guide rail 32. Then, it enters the material distribution plate 34 mentioned above through the linear vibrating guide rail 32. In this embodiment, the material distribution plate 34 has two channels, which can support the feeding of two sets of valve bodies to the linear vibrating guide rail 32 and the unloading of two sets of valve bodies. Of course, the width of the channel mentioned in this embodiment should be adapted to the outer diameter of the valve body to avoid tilting during the conveying process.

[0059] When the valve body is conveyed to the tail end of the distribution plate 34, in the initial state, the two sets of valve bodies at the tail end will enter the groove 351 of the sliding plate 35. At this time, the distribution cylinder 30 can be activated to move. The distribution cylinder 30 pulls the sliding plate 35 to move laterally, and the sliding plate 35 can carry the two valve bodies in its groove 351 to move laterally and move to the side away from the slide, so as to facilitate the subsequent picking and transferring of the valve bodies.

[0060] Reference Figure 6 Based on the above embodiments, the valve body feeding mechanism 3 of the present invention further includes;

[0061] The upper slide plate 36 is slidably connected in the frame 33. The upper slide plate 36 is slidably connected inside the frame 33 via a guide rail and a slider. A transverse cylinder 37 is fixedly installed on the side of the frame 33 to drive the upper slide plate 36 to move laterally. It should be noted that in this embodiment, a groove should be opened at the top of the frame 33, and the top of the upper slide plate 36 is slidably connected in the groove.

[0062] The upper slide plate 36 is slidably connected to the carrier plate at its front end. Two clamping members 38 are installed at the front end of the carrier plate. A longitudinal cylinder 39 is fixedly installed at the upper end of the upper slide plate 36 to drive the carrier plate to move up and down.

[0063] Preferably, in this embodiment, since the valve body has a cylindrical structure, the clamping member 38 described in this embodiment can be set as a pneumatic gripper to facilitate clamping.

[0064] When the valve body moves to one side along with the sliding plate 35, the longitudinal cylinder 39 drives the clamping member 38 to move up and down to grab the valve body. After the grabbing is completed, it can be reset upward. Then, the transverse cylinder 37 drives the clamping member 38 to move laterally. When it moves to the valve body mounting hole of the corresponding fixture 20, the longitudinal cylinder 39 drives the clamping member 38 to move up and down to put the valve body into the valve body mounting hole. In this way, the loading of the valve body can be completed.

[0065] Afterwards, the clamping part 38 is reset, and the sliding plate 35 is also reset. Then, when the turntable 2 continues to rotate and the next fixture 20 is rotated into place, the above steps can be repeated to perform the loading operation.

[0066] Reference Figure 7 Furthermore, in this embodiment, the valve body detection mechanism 4 includes a column 41 fixed on the machine base 1. A guide plate 43 is installed on the upper end of the column 41 via a detection cylinder 42. The detection cylinder 42 is fixedly connected to the column 41 via a connecting seat. The guide plate 43 is installed on the shaft end of the detection cylinder 42.

[0067] Two spring probe assemblies 44 are installed on the end face of the guide plate 43. Specifically, the spring probe assembly 44 in this embodiment includes a probe and a spring. The probe and the guide plate 43 are inserted and passed through each other. The spring is connected between the guide plate 43 and the probe. A sensor 45 for detecting the position of the probe in the spring probe assembly 44 is also fixedly installed on the upper side of the guide plate 43.

[0068] Specifically, in this embodiment, the sensor 45 is configured as a U-shaped photoelectric switch, which is fitted onto the outside of the probe. Since the valve body has an asymmetrical stepped structure, it is only necessary to determine whether the valve body is installed in reverse by measuring the insertion depth of the probe.

[0069] Specifically, when the fixture 20 carries the valve body into the lower part of the valve body detection mechanism 4, the detection cylinder 42 pushes the guide plate 43 to move downward a predetermined distance. If the valve body is installed in the correct orientation, taking the step position inside the valve body as an example where the upper part is shallow and the lower part is deep, the spring probe assembly 44 abuts against the internal step of the valve body. At this time, the probe will move upward and enter the interior of the sensor 45. At this time, the sensor 45 generates a detection signal, which means that the valve body is installed correctly.

[0070] Conversely, if the valve body is installed in the opposite direction, because the lower part of the valve body is deeper, the probe will not bounce when the spring probe assembly 44 moves down a predetermined distance. At this time, the sensor 45 cannot detect the probe, so there is no signal. The current valve body is marked as a defective product and will not be further assembled. At the same time, it will be separated from the finished product during the subsequent material cutting process to ensure that all valve bodies on the fixture 20 can maintain the correct position and enter the subsequent process.

[0071] Reference Figure 8 , Figure 9 , Figure 10 In some embodiments, the film loading mechanism 5 of the present invention includes a base plate 51 and a top plate 52 slidably connected to the base plate 51. A push cylinder 53 is installed on the base plate 51 to drive the top plate 52 to move laterally. That is, in this embodiment, the entire top plate 52 can be driven to move linearly by the push cylinder 53. Of course, in this embodiment, the top plate 52 can be slidably connected to the base plate 51 by a guide rail and a slider.

[0072] The top plate 52 is equipped with an unwinding assembly 54 and a winding assembly 55 for unwinding and rewinding film rolls, and the bottom plate 51 is equipped with a punching assembly 56.

[0073] Reference Figure 10 Specifically, both the unwinding assembly 54 and the rewinding assembly 55 described in this invention include upright plates. A motor is fixedly mounted on the upright plate, and a reel is rotatably connected to it. The motor drives the reel to rotate, i.e., the shaft end of the motor is connected to the reel to realize unwinding and rewinding operations. Several guide wheels are rotatably connected to each upright plate, and the film roll moves in different directions along the guide wheels. In addition, in order to detect the tension of the film during unwinding and rewinding, a sliding wheel can also slide on each of the two upright plates in this embodiment. A detection plate is fixedly mounted on the wheel frame of the sliding wheel. At the same time, two U-shaped photoelectric sensors are also fixedly mounted on the upright plates. The two U-shaped photoelectric sensors are used to detect the maximum vertical movement position of the detection plate of the sliding wheel. In this way, when the film is too loose, the rotation speed of the unwinding motor can be slowed down and the rotation speed of the rewinding motor can be increased to ensure stable delivery of the film.

[0074] In addition, a membrane suction plate 58 is driven to move above the base plate 51 by a membrane suction cylinder 57. Of course, the membrane suction cylinder 57 is fixed on the base plate 51. A suction head 59 is fixedly installed on the end face of the membrane suction plate 58. The suction head 59 is used to connect to negative pressure to achieve negative pressure suction of the membrane during the membrane loading process. The suction head 59 is opposite to the valve body mounting hole on the fixture 20.

[0075] As can be seen from the above, since the valve body mounting hole on the fixture 20 in this embodiment adopts a stepped through hole design, while ensuring the bearing capacity of the valve body, during the film loading stage, the film suction cylinder 57 can also drive the film suction plate 58 to move upward so that the two suction heads 59 on the film suction plate 58 can be inserted into the lower side of the stepped through hole. In this way, when the film punching assembly 56 punches the roll film, the negative pressure suction of the suction head 59 can be used to ensure that the cut film can smoothly enter the interior of the valve body, avoiding problems such as sliding out or shifting with the suction head 59.

[0076] Reference Figure 8Based on the above embodiments, the film punching assembly 56 of the present invention includes a second column 561 fixed on the base plate 51, an opening above the top plate 52 to avoid the second column 561, a support plate 562 fixedly installed above the second column 561, a film punching mounting plate 564 driven to slide at the front end of the support plate 562 by a film punching cylinder 563, the film punching cylinder 563 being fixed above the support plate 562, two film punching heads 565 being fixedly installed at the front end of the film punching mounting plate 564, a film clamping plate 566 with a perforation being fixedly installed in front of the support plate 562, the film roll passing through the perforation, and a through hole 567 opposite to the film punching head 565 being opened on the film clamping plate 566.

[0077] In actual operation, the unwinding assembly 54 and the winding assembly 55 unwind the film, which passes through the perforation of the clamping plate 566. When the fixture 20 carrying the valve body enters below the clamping plate 566, the punching cylinder 563 drives the punching mounting plate 564 to move downward. At this time, the punching head 565 moves into the through hole 567 of the clamping plate 566 to punch and cut the film, and press the punched film into the interior of the valve body. The suction head 59 attracts the film to ensure the stability of the film installation. After that, the punching head 565 resets to wait for the next punching action.

[0078] Reference Figure 4 It should be noted that the membrane detection mechanism 6, copper sheet detection mechanism 8, and fixture detection mechanism 11 described in this embodiment have the same structure, as shown in the reference. Figure 12 The copper sheet loading mechanism 7 and the valve body feeding mechanism 3 have the same structure;

[0079] Reference Figure 11 The membrane detection mechanism 6 includes a column 61 and a mounting base 62 fixed on the column 61, with a sensor 63 fixed above the mounting base 62.

[0080] Once the diaphragm is installed, the turntable 2 continues to rotate, causing the valve body carrying the diaphragm to enter below the membrane detection mechanism 6. The diaphragm is then detected by sensor 63 to ensure that the diaphragm is installed in place. Preferably, in this embodiment, sensor 63 is set as an optical fiber sensor.

[0081] Of course, after the diaphragm is inspected, the turntable 2 will drive the valve body loaded with the diaphragm into the copper sheet loading mechanism 7. The specific operation of the copper sheet loading mechanism 7 described in this embodiment can be referred to the description of the valve body feeding mechanism 3 above, and will not be repeated here. That is, the copper sheet in the vibratory plate is transported to the distribution plate 34 by the copper sheet loading mechanism 7, and then the copper sheet is transferred to the upper part of the valve body and placed in by the clamping member 38. It should be noted that, in this embodiment, since the copper sheet is a sheet structure, the pneumatic gripper method may have the problem of inconvenient gripping. Therefore, the clamping member 38 of the copper sheet loading mechanism 7 in this embodiment can be set as a suction cup to pick up the copper sheet to ensure the reliability of the copper sheet transfer.

[0082] Similarly, after the copper sheet is installed, the turntable 2 drives the fixture 20 to rotate to the bottom of the copper sheet detection mechanism 8. The sensor 63 of the copper sheet detection mechanism 8 can detect whether the current valve body has a copper sheet installed. Since the optical properties of the diaphragm and the copper sheet are different, the design of the fiber optic sensor can be used to determine whether the valve body with the diaphragm has a copper sheet installed.

[0083] Reference Figure 13 , Figure 14 Furthermore, in this embodiment, the riveting mechanism 9 includes two frames 91 fixed on the machine base 1. An adjusting seat 93 is slidably driven by a riveting cylinder 92 at the front end of the frame 91. Of course, the riveting cylinder 92 is fixed above the frame 91. A riveting head 94 is fixedly installed at the bottom of the adjusting seat 93. A stamping plate 95 is also installed at the bottom of the frame 91. A stamping cylinder 96 is fixed on the outer side of the frame 91 to drive the stamping plate 95 to move laterally.

[0084] Specifically, in this embodiment, the riveting head 94 is used to deform the upper end of the valve body of the riveting head 94 by the riveting cylinder 92 when the fixture 20 enters the riveting mechanism 9, so as to press and fix the copper sheet inside the entire valve body, thereby realizing the processing and forming of the constant flow valve. Of course, in this embodiment, the stamping plate 95 is stopped below the fixture 20. As can be seen from the above description, since the fixture 20 needs to enter each mechanism in sequence, one side of the fixture 20 extends to the outside of the entire turntable 2. To ensure the stress distribution of the fixture 20 during the stamping process, this embodiment uses a movable stamping plate 95 to support the bottom of the fixture 20, thereby ensuring its stress stability during the riveting process. It should be noted that the stamping plate 95 in this embodiment has a stepped structure. When it is necessary to support the fixture 20, it is pushed forward by the stamping cylinder 96 to the bottom of the fixture 20. After the riveting is completed, the stamping cylinder 96 drives the entire fixture 20 to retract, thus avoiding interference of the stamping plate 95 with the rotation of the fixture 20.

[0085] Reference Figure 15 , Figure 16 Based on the above embodiments, the feeding mechanism 10 of the present invention includes a frame three 101 installed on the machine base 1. Two feeding hoppers 102 are fixedly installed inside the frame three 101, and a distributing hopper 104 is driven to rotate inside the frame three 101 by a motor 103. The distributing hopper 104 has one inlet and two outlets, that is, the inside of the distributing hopper 104 forms a triangular channel.

[0086] A feeding plate 105 slides laterally inside the frame 3 101. The front end of the feeding plate 105 is slidably connected to the clamping plate 106. Two pneumatic grippers 107 are fixedly installed at the front end of the clamping plate 106. A feeding cylinder 108 that drives the feeding plate 105 to move laterally is fixedly installed at the top of the frame 3 101. Of course, in this embodiment, a slide rail is also opened above the frame 3 101. The upper end of the feeding plate 105 is slidably connected in the slide rail. A feeding cylinder 2 109 that drives the clamping plate 106 to move up and down is fixedly installed above the feeding plate 105. Of course, in this embodiment, two pneumatic grippers 107 are also provided, which can simultaneously feed the two constant flow valves on the fixture 20.

[0087] When the formed constant flow valve continues to rotate with the turntable 2 and enters the unloading mechanism 10, the unloading cylinder 108 drives the unloading plate 105 to move the pneumatic gripper 107 laterally until it moves above the fixture 20. Then, the unloading cylinder 109 pushes the pneumatic gripper 107 downward to complete the gripping of the constant flow valve. Afterward, the pneumatic gripper 107 resets and moves above the distribution hopper 104 and is placed into the distribution hopper 104. The valve can be distinguished according to the quality of the product, such as... When the product is qualified, the constant flow valve enters the feed hopper 102 on one side along the feed hopper 104. At this time, the feed hopper 104 is tilted to the side facing the feed hopper 102. At the same time, when the product is unqualified, the motor 103 drives the feed hopper 104 to rotate and tilt to the other side. At this time, the product can slide down the feed hopper 104 into the feed hopper 102 on the other side. Of course, in this embodiment, two material boxes can also be installed on the machine 1 to collect the finished products and defective products discharged from the two feed hoppers 102 respectively.

[0088] Of course, after the material is unloaded, there will be no constant flow valve product in the fixture 20. In order to avoid unloading failure, the present invention also provides a fixture detection mechanism 11. That is, when the turntable 2 continues to rotate to drive the current fixture 20 to perform cyclic feeding, the fixture 20 will pass under the fixture detection mechanism 11. The sensor 63 on the fixture detection mechanism 11 will detect the valve body mounting hole in the fixture 20 to determine whether the constant flow valve has been unloaded. The sensor 63 mentioned in this embodiment can be a fiber optic sensor or a photoelectric sensor. Those skilled in the art can make an adaptive choice, which will not be elaborated here.

[0089] Furthermore, this invention also proposes an automated method for assembling a constant flow valve, using the assembly machine described above. Specifically, this method includes the following steps:

[0090] S100 drives multiple fixtures 20 to rotate circumferentially via turntable 2;

[0091] S200, each fixture 20 first enters the lower part of the valve body loading mechanism 3 to load the valve body, and after loading, it continues to rotate to the lower part of the valve body detection mechanism 4 to perform forward and reverse detection of the valve body;

[0092] S201, when the valve body detection mechanism 4 detects that the valve body is in the opposite position, the product is marked as defective and will not proceed to the next process; otherwise, the turntable 2 drives the fixture 20 to continue rotating and enter the next process.

[0093] S300, the fixture 20 continues to rotate to the bottom of the membrane loading mechanism 5 to fill the constant current membrane. After the filling is completed, the membrane detection mechanism 6 detects the installation status of the constant current membrane.

[0094] S301, when the membrane inspection mechanism 6 detects a missing membrane, the product is marked as defective and will not proceed to the next process; otherwise, the turntable 2 drives the fixture 20 to continue rotating and enter the next process.

[0095] S400, the fixture 20 continues to rotate to the bottom of the copper sheet loading mechanism 7 to load copper sheets, with the copper sheets covering the constant current membrane. Similarly, after the copper sheets are installed, the fixture 20 rotates to the bottom of the copper sheet detection mechanism 8 to detect the copper sheets.

[0096] S401, when the copper sheet detection mechanism 8 detects that a copper sheet is missing, the product is marked as defective and will not proceed to the next process; otherwise, the turntable 2 drives the fixture 20 to continue rotating and enter the next process.

[0097] S500, the fixture 20 continues to rotate to below the riveting mechanism 9, so that the valve body can limit and lock the copper sheet by punching the end of the valve body. At this time, the valve body assembly is completed. During subsequent rotation, the forming part can be unloaded by the unloading mechanism 10.

[0098] S501, during material feeding, when both products are defective, the two pneumatic grippers 107 of the feeding mechanism 10 simultaneously feed the two defective products into the defective product feeding hopper 102; otherwise, they are all fed into the finished product feeding hopper 102. When one product is a finished product and the other is a defective product, the two pneumatic grippers 107 move sequentially to cooperate with the dispensing hopper 104 to feed the finished product and the defective product separately.

[0099] S600, the fixture 20 after the material is cut enters the fixture inspection mechanism 11 for part inspection. Once the part in the fixture 20 is cut, the above steps can be repeated to achieve continuous assembly of the valve body.

[0100] S601, when the fixture detection mechanism 11 detects that the constant flow valve in the current fixture 20 has not finished feeding, it reminds the user to make adjustments; otherwise, the turntable 2 drives the fixture 20 to continue rotating into the next assembly cycle.

[0101] In summary, the assembly machine of the present invention is used to realize the automated continuous assembly of the constant flow valve body, constant flow diaphragm and copper sheet, thereby improving the overall production efficiency of the constant flow valve.

[0102] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
