Technical Field

[0001] This application relates to the technical field of thermostat assembly equipment, and in particular to an adjusting shaft feeding mechanism and a thermostat housing assembly machine. Background Technology

[0002] Thermostats are key devices in home appliances, HVAC systems, and other equipment or systems. They work by using temperature-sensing elements to detect temperature changes and then controlling the circuit to connect or disconnect the power supply, thereby controlling the temperature control equipment.

[0003] Chinese patent CN223728679U discloses a liquid expansion thermostat, which includes an upper housing and a lower housing. The outer side of the lower housing is provided with a plurality of engaging grooves. The upper housing is provided with a plurality of engaging parts that are adapted to the engaging grooves for locking the upper housing and the lower housing. The upper housing is also provided with a dustproof plate for blocking the opening. The interior of the upper housing and the lower housing is provided with a temperature control structure for realizing temperature control.

[0004] To improve the assembly efficiency of thermostats, existing thermostat assembly machines typically assemble the housing (upper housing mentioned above) and the base (lower housing mentioned above) separately, and then perform final assembly. For example... Figure 17 , Figure 18 As shown, a thermostat housing generally includes a housing, an adjusting shaft, a limiting plate, a gasket, and screws. Existing thermostat housing assembly machines have the following drawbacks: During assembly, it is difficult to ensure consistent screw-in precision of the adjusting shaft. When screwed in too deeply or too shallowly, it severely affects the performance and quality of the thermostat, resulting in poor product quality consistency and stability. Summary of the Invention

[0005] To improve the assembly quality of thermostat housings, this application provides an adjusting shaft feeding mechanism and a thermostat housing assembly machine.

[0006] The adjusting shaft feeding mechanism and temperature controller housing assembly machine provided in this application adopt the following technical solution: An adjustable shaft feeding mechanism includes, The feeding unit includes an adjusting shaft feed channel and a positioning seat fixedly connected to the end of the adjusting shaft feed channel. A transfer seat for placing the adjusting shaft is slidably connected inside the positioning seat. A transfer cylinder for pushing the transfer seat is fixedly connected to the side wall of the positioning seat. A gripping unit for taking out the adjusting shaft is provided above the positioning seat. The fastening unit includes a rotating disk, a mounting frame disposed on one side of the rotating disk, a lifting platform slidably connected to the side wall of the mounting frame, a first cylinder for driving the lifting platform to move, a limiting frame fixedly connected to the top wall of the lifting platform, a conveying block slidably connected to the top wall of the lifting platform, a second cylinder for driving the conveying block to move, a first tightening shaft slidably connected to the side wall of the mounting frame, and a third cylinder for driving the first tightening shaft to move. A transfer platform is disposed on one side of the rotating disk. The top walls of both the rotating disk and the transfer platform are provided with mounting seats for placing the adjusting shaft. The limiting frame has a screw inlet hole, the conveying block has a placement hole communicating with the screw inlet hole, and the lifting platform has a discharge hole at the end near the rotating disk. The first tightening shaft is directly opposite the discharge hole. A conveying unit for moving the adjusting shaft.

[0007] By adopting the above technical solution, the screw can be accurately placed inside the adjusting shaft, and the screwing depth can be controlled by the first tightening shaft, thereby achieving a stable assembly effect. At the same time, the conveying unit and the flipping unit can make the adjusting shaft stably placed on the rotating plate. The rotation of the rotating plate moves the adjusting shaft to below the feeding hole, and the first tightening shaft can move, thereby ensuring the stable tightening of the screw.

[0008] Optionally, the gripping unit includes a fixed plate, a sliding plate slidably connected to one side of the fixed plate, a drive cylinder fixedly connected to the bottom of the fixed plate for driving the sliding plate to move, a clamping cylinder rotatably connected to the side of the sliding plate near the positioning seat, and a rotary motor fixedly connected to the side wall of the sliding plate for rotating the clamping cylinder. A first proximity switch directly opposite the sliding plate is fixedly connected to the top wall of the fixed plate.

[0009] By adopting the above technical solution, the gripping unit can remove the adjusting shaft from the positioning seat. The rotary motor, in conjunction with the clamping cylinder, enables the adjusting shaft to be rotated to the required direction, thus facilitating the subsequent conveying unit to transport the adjusting shaft to the rotating plate for subsequent fastening and installation operations. The drive cylinder pushes the sliding plate, enabling the clamping cylinder to adjust its height. This, in conjunction with the conveying unit, achieves a fast production cycle and improves production efficiency.

[0010] Optionally, the conveying unit includes a support plate, a sliding table that slides horizontally on the side wall of the support plate, a conveying cylinder fixedly connected to the side wall of the support plate for pushing the sliding table, a mechanical gripper that slides vertically on the side wall of the sliding table, a gripper lifting cylinder fixedly connected to the side wall of the sliding table for pushing the mechanical gripper, and a tightening assembly that slides vertically on the side wall of the sliding table.

The output shaft of the second tightening shaft is fixedly connected to a locking sleeve for clamping the adjusting shaft.

[0011] By adopting the above technical solution, the two mechanical grippers arranged side by side can achieve simultaneous clamping and movement of multiple workstations. One can move the adjusting shaft on the clamping cylinder to the rotating plate, and the other can move the adjusting shaft on the rotating plate with screws already installed to the central transfer platform. The tightening assembly moves the adjusting shaft on the central transfer platform to the housing of the temperature controller and tightens it, eliminating the waiting time at each workstation and improving production efficiency.

[0012] Optionally, a trigger disc is fixedly connected to the outer periphery of the second tightening shaft, and a sensor for detecting the number of rotations and angle of the trigger disc is fixedly connected to the side wall of the mounting platform.

[0013] By adopting the above technical solution, the trigger disc, in conjunction with the sensor, can accurately detect the number of rotations of the second tightening shaft and provide feedback. Combined with the existing pitch parameters of the adjusting shaft thread, the depth to which the adjusting shaft has entered the housing can be calculated, thereby achieving closed-loop control and ensuring that the depth to which each adjusting shaft enters the housing is consistent, thus guaranteeing product consistency.

[0014] Optionally, the limiting frame and the lifting platform form a guide hole for the conveying block to pass through, and limiting blocks are fixedly connected to both sides of the conveying block.

[0015] By adopting the above technical solution, the guide hole, in conjunction with the second cylinder, effectively constrains the movement path of the conveying block, thereby ensuring that the placement hole is aligned with the feeding hole and ensuring stable feeding of the screw.

[0016] Optionally, the mounting base includes a clamp fixedly connected to the top wall of the turntable and the rotating disk, a sliding rod passing through and sliding on the clamp, and a clamping block fixedly connected to the sliding rod. An abutment cap is fixedly connected to one end of the sliding rod away from the clamping block. A spring sleeved on the sliding rod is provided between the abutment cap and the side wall of the clamp. An unlocking cylinder for pushing the sliding rod is provided on one side of both the rotating disk and the turntable.

[0017] By adopting the above technical solution, the spring and the abutment cap enable the clamping block to always move towards the side of the clamping seat, so that after the adjusting shaft is placed in the clamping seat, the clamping block can be tightly attached to the adjusting shaft and pressed, so that the adjusting shaft will not shake during the entire assembly process, which facilitates transportation and assembly.

[0018] A thermostat housing assembly machine includes a workbench, a rotary table rotatably connected to the top wall of the workbench, and a fixture fixedly connected to the top wall of the rotary table. Along the rotation direction, the outer side of the rotary table is sequentially provided with a gasket feeding mechanism, a housing feeding mechanism, a housing pressing mechanism, an oil injection mechanism, the aforementioned adjusting shaft feeding mechanism, a limit plate mounting mechanism, a limit plate fastening mechanism, and a discharge mechanism.

The housing feeding mechanism includes a housing feeding channel fixedly connected to the top wall of the workbench and a housing moving unit for moving the housing to the fixture.

[0019] By adopting the above technical solution, the gasket is first placed on the fixture, and then the housing is placed on the fixture. The housing clamping mechanism enables the gasket and the housing to be stably engaged. The oil injection mechanism enables the gasket to be lubricated, which facilitates the subsequent installation of the adjustment shaft. The limit plate installation mechanism rotates the limit plate and then places it on the adjustment shaft, and then fastens it through the limit plate fastening mechanism, thereby completing the assembly of the entire thermostat housing. Finally, the finished product is taken out through the discharge mechanism.

[0020] Optionally, the limiting piece installation mechanism includes a limiting piece feed channel fixedly connected to the top wall of the workbench, a positioning frame fixedly connected to the top wall of the workbench, a moving plate slidably connected to the side wall of the positioning frame, a lifting plate slidably connected to the side wall of the moving plate, and a limiting piece gripper fixedly connected to the side wall of the lifting plate. A picking cylinder for driving the lifting plate is fixedly connected to the top wall of the moving plate. Two limiting piece grippers are arranged side by side. A receiving platform is fixedly connected to the side wall of the positioning frame. A direction-selecting seat for placing the limiting piece is rotatably connected to the top wall of the receiving platform. A drive motor for driving the direction-selecting seat to rotate is fixedly connected to the bottom wall of the receiving platform. A sensing control device is fixedly connected to the top wall of the receiving platform. A trigger plate for triggering the sensing control device is fixedly connected to the side wall of the direction-selecting seat.

[0021] By adopting the above technical solution, the limiting piece moves to the orientation seat through the limiting piece gripper, and the orientation seat is rotated by the drive motor at the bottom, thereby completing the rotation of the limiting piece. Then, the limiting piece is moved to the fixture by the second limiting gripper, thus completing the orientation and installation of the limiting piece.

[0022] Optionally, the discharge mechanism includes a first discharge channel fixedly connected to the top wall of the workbench, a discharge support plate fixedly connected to the top wall of the workbench, a switching cylinder fixedly connected to the side wall of the discharge support plate, a second discharge channel fixedly connected to the output shaft of the switching cylinder, a discharge clamping arm slidably connected to the side wall of the discharge support plate, and a discharge moving unit for driving the discharge clamping arm to move. A detection unit is also provided between the discharge mechanism and the limiting plate fastening mechanism. The detection unit includes a seat fixedly connected to the top wall of the workbench, a detection block slidably connected to the side wall of the seat, a pressing column passing through and sliding on the detection block, a limiting ring fixedly connected to the outer periphery of the pressing column, a second proximity switch fixedly connected to the side wall of the detection block and directly opposite the limiting ring, and a detection cylinder for driving the detection block to move.

[0023] By adopting the above technical solution, the detection unit can detect whether the limit plate is installed in place, and the switching cylinder of the discharge mechanism can switch the discharge track, thereby realizing the separate transportation of good and defective products.

[0024] Optionally, the housing clamping mechanism includes a clamping table fixedly connected to the top wall of the workbench, a pressing member slidably connected to the side wall of the clamping table, and a pressing cylinder fixedly connected to the top wall of the clamping table for driving the pressing member to press down. The limiting plate fastening mechanism has the same structure as the housing clamping mechanism. The oil injection mechanism includes an oil injection frame fixedly connected to the top wall of the workbench, an oil gun slidably connected to the side wall of the oil injection frame, and an oil injection drive unit for driving the oil gun to move.

[0025] By adopting the above technical solution, the housing pressing mechanism presses down to make the gasket and the housing stably engaged, thereby ensuring that the subsequent adjustment shaft can be stably installed. The limiting plate fastening mechanism enables the limiting plate to be connected to the adjustment shaft, ensuring that the installation is in place.

[0026] In summary, this application has the following beneficial effects: 1. The fastening unit enables stable and rapid installation of screws. The trigger plate and sensor of the second tightening shaft work together to accurately calculate the screw-in depth, thereby achieving closed-loop control and ensuring that the screw-in depth of each adjusting shaft is consistent, thus guaranteeing the consistency of product assembly accuracy.

[0027] 2. The limit plate installation mechanism, in conjunction with the sensing control device, ensures that the limit plate is always installed into the adjusting shaft at a fixed angle, thereby achieving the orientation and installation of the limit plate and ensuring consistent assembly.

[0033] During the assembly of the thermostat housing, the gasket feeding mechanism 5 first places the gasket on the fixture 411. As the rotary table 41 rotates, the housing feeding mechanism 6 places the housing on the fixture 411. At this time, the gasket is below the housing. The housing fastening mechanism presses down so that the gasket can be smoothly inserted into the housing, completing the fastening of the housing and the gasket. Then, the gasket is lubricated by the oil injection mechanism 8. The adjusting shaft feeding mechanism installs the adjusting shaft on the top of the housing and connects it with the gasket. The limiting plate installation mechanism 9 fits the limiting plate onto the adjusting shaft, and the limiting plate fastening mechanism 10 achieves the fastening connection between the limiting plate and the adjusting shaft. At this time, the assembly of the thermostat housing is completed, and finally it is sent out by the discharge mechanism 110.

The oiling mechanism 8 includes an oiling frame 81, an oil gun 82, and an oiling drive unit 83. The oiling frame 81 is fixedly connected to the top wall of the worktable 4, the oil gun 82 is slidably connected to the side wall of the oiling frame 81, and the oiling drive unit 83 is fixedly connected to the top wall of the oiling frame 81 to drive the oil gun 82 to move up and down. During oiling, the oiling drive unit 83 drives the oil gun 82 to descend, so that the oil gun 82 nozzle can approach the adjustment column mounting hole of the housing to achieve accurate drip lubrication.

[0037] Reference Figure 6 , Figure 7 The adjusting shaft feeding mechanism includes a feeding unit 1, a fastening unit 2, and a conveying unit 3. The feeding unit 1 is used to neatly arrange the adjusting shafts into a specific posture so that the conveying unit 3 can clamp them. The feeding unit 1 includes an adjusting shaft feeding channel 11, a positioning seat 12, a transfer seat 121, and a transfer cylinder 122. The adjusting shaft feeding channel 11 is fixedly connected to the top of the workbench 4. The adjusting shaft feeding channel 11 is powered by a linear vibrator at the bottom. The positioning seat 12 is fixedly connected to one end of the adjusting shaft feeding channel 11 near the fastening unit 2 and communicates with the adjusting shaft feeding channel 11. The transfer seat 121 is slidably connected inside the positioning seat 12 for placing and removing a single adjusting shaft. A gripping unit 13 is provided above the positioning seat 12 for removing the adjusting shaft from the transfer seat 121. The transfer cylinder 122 is fixedly connected to the side wall of the positioning seat 12. The output shaft of the transfer cylinder 122 is fixedly connected to the side wall of the transfer seat 121, thereby conveying the transfer seat 121 to the bottom of the gripping unit 13.

The gripping unit 13 includes a fixed plate 131, a sliding plate 132, a drive cylinder 133, a clamping cylinder 134, and a rotary motor 135. The fixed plate 131 is fixedly connected to the top wall of the worktable 4 and is located on one side of the positioning seat 12. The sliding plate 132 is slidably connected to the side wall of the fixed plate 131 in the vertical direction. The drive cylinder 134... A drive cylinder 133 is fixedly connected to the side wall of the fixed plate 131 and positioned below the sliding plate 132. The output shaft of the drive cylinder 133 is fixedly connected to the outer wall of the sliding plate 132 to achieve the lifting and lowering of the sliding plate 132. A clamping cylinder 134 is rotatably connected to the side wall of the sliding plate 132 near the positioning seat 12. A rotary motor 135 is fixedly connected to the side wall of the sliding plate 132 away from the clamping cylinder 134, and drives the clamping cylinder 134 to rotate via the rotary motor 135. To achieve stroke control of the clamping cylinder 134, a first proximity switch 1311 is fixedly connected to the top wall of the fixed plate 131, facing the sliding plate 132, thereby achieving position detection of the sliding plate 132.

[0039] During the conveying process of the adjusting shaft, as the adjusting shaft feed channel 11 moves and enters the transfer seat 121, the transfer cylinder 122 pushes the transfer seat 121 to below the clamping cylinder 134. The drive cylinder 133 drives the sliding plate 132 to descend, causing the clamping cylinder 134 to clamp the adjusting shaft. The rotary motor 135 starts and rotates the clamping cylinder 134 to achieve the adjustment of the adjusting shaft's posture.

[0040] Reference Figure 6 , Figure 8 The fastening unit 2 is located on the side of the feeding unit 1 near the rotary table 41. The fastening unit 2 includes a rotating disk 21 rotatably connected to the top of the worktable 4, a mounting frame 22 fixedly connected to the top of the worktable 4, a lifting platform 23 slidably connected to the side wall of the mounting frame 22, a limiting frame 231 fixedly connected to the top wall of the lifting platform 23, a conveying block 232 slidably connected to the top wall of the lifting platform 23, and a first tightening shaft 26 slidably connected to the side wall of the mounting frame 22. The side wall of the mounting frame 22 is fixedly connected to a device for driving the lifting platform 23 to rise and fall. The first cylinder 24, the second cylinder 25 for pushing the conveyor block 232 is fixedly connected to the side wall of the lifting platform 23, the third cylinder 27 for pushing the first tightening shaft 26 to rise and fall is fixedly connected to the top wall of the mounting frame 22, the top wall of the limiting frame 231 is provided with a screw feeding hole 2311, the conveyor block 232 is provided with a placement hole 2321 communicating with the screw feeding hole 2311, the lifting platform 23 is provided with a discharge hole 233 at one end near the rotating disk 21, and the first tightening shaft 26 is located above the lifting platform 23 and directly opposite the discharge hole 233.

[0041] After the adjusting shaft is placed on the rotating disk 21, the rotating disk 21 rotates and moves the adjusting shaft below the discharge hole 233. The first cylinder 24 is activated so that the lifting platform 23 can get close to the adjusting shaft. The screw enters the screw feed hole 2311 through conventional conveying components such as the vibrating disk and falls into the placement hole 2321 under gravity. The second cylinder 25 is activated to push the conveying block 232 to move so that the placement hole 2321 is directly opposite the discharge hole 233. At this time, the screw can fall from the discharge hole 233 into the adjusting shaft. The third cylinder 27 is activated so that the first tightening shaft 26 passes through the discharge hole 233 and tightens the screw into the adjusting shaft. To ensure that the placement hole 2321 of the conveyor block 232 can be accurately aligned with the feeding hole 233 and the screw feeding hole 2311, the limit frame 231 and the lifting platform 23 form a guide hole 234 for the conveyor block 232 to pass through. Limit blocks 2322 are fixedly connected to both sides of the conveyor block 232 to limit the movement direction and maximum stroke of the conveyor block 232, thereby ensuring the stability of screw transportation.

[0042] Reference Figure 6 , Figure 8 and Figure 10 A central turntable 28 is fixedly connected to the top wall of the worktable 4 on one side of the rotating disk 21. Both the rotating disk 21 and the central turntable 28 are provided with mounting seats 29 for clamping the adjusting shaft. There are two mounting seats 29 on the rotating disk 21. When installing screws, one mounting seat 29 can be positioned below the first tightening shaft 26 to prepare for tightening the screws, while the other mounting seat 29 is used to remove the adjusting shaft that has been tightened and insert a new adjusting shaft, thereby achieving a fast production cycle.

[0043] Reference Figure 8 , Figure 10 The mounting base 29 includes a clamp 291 fixedly connected to the top wall of the transfer platform 28 and the rotating disk 21, a sliding rod 292 passing through and sliding on the clamp 291, and a clamping block 293 fixedly connected to the sliding rod 292. An abutment cap 2921 is fixedly connected to one end of the sliding rod 292 away from the clamping block 293. A spring 294, sleeved on the sliding rod 292, is provided between the abutment cap 2921 and the side wall of the clamp 291. Under the action of the spring 294, the abutment cap 2921 always moves towards... The movement away from the clamp 291 causes the clamp 293 and the clamp 291 to move closer together, thereby securing the adjusting shaft and preventing it from falling off during transport. Both the rotating disk 21 and the central turntable 28 are equipped with unlocking cylinders 295 for pushing the sliding rod 292. The unlocking cylinders 295 can push the adjusting shaft, causing the spring 294 to be compressed. At this time, the clamp 293 and the clamp 291 separate, making it easier for the mechanical gripper 34 and the tightening assembly 36 to position and pick up the object.

Two mechanical grippers 34 are arranged side by side, and two corresponding gripper lifting cylinders 35 are also arranged. The mechanical gripper 34 near the feeding unit 1 is used to move the adjusting shaft on the gripping cylinder 134 to the mounting seat 29 of the rotating disk 21. The mechanical gripper 34 near the tightening assembly 36 is used to move the adjusting shaft from the rotating disk 21 to the mounting seat 29 of the transfer table 28. The tightening assembly 36 is located on the sliding table 32 near the rotating table 41 and is used to move the adjusting shaft on the transfer table 28 to the fixture 411 for tightening. Since both the mechanical grippers 34 and the tightening assembly 36 are connected to the sliding table 32, multiple gripping and conveying actions can be performed simultaneously, thereby ensuring production efficiency.

[0045] Reference Figure 11 , Figure 12 The tightening assembly 36 includes a lifting plate 361, a lifting seat 363, a first lifting cylinder 362, a second lifting cylinder 364, a mounting platform 365, and a second tightening shaft 366. The lifting plate 361 is slidably connected to the side wall of the sliding platform 32 in the vertical direction. The first lifting cylinder 362 is fixedly connected to the top wall of the sliding platform 32 to drive the lifting plate 361 to move up and down. The lifting seat 363 is slidably connected to the side wall of the lifting plate 361. The second lifting cylinder 364 is fixedly connected to the top wall of the lifting plate 361 to drive the lifting seat 363 to move up and down. The mounting platform 365 is fixedly connected to the side wall of the lifting seat 363 to support the second tightening shaft 366. The output shaft of the second tightening shaft 366 passes through the mounting platform 365. The first lifting cylinder 362 and the second lifting cylinder 364 realize multi-stage lifting adjustment of the second tightening shaft 366, which can take into account the accuracy of assembly rhythm and screw-in depth, and avoid the adjustment shaft from being unable to align with the installation position on the housing due to excessive stroke of a single cylinder.

[0046] To ensure that the second tightening shaft 366 can stably clamp the adjusting shaft, a locking sleeve 367 for clamping the adjusting shaft is fixedly connected to the end of the second tightening shaft 366. When the second tightening shaft 366 rotates, the adjusting shaft can rotate stably, ensuring consistent installation depth. With the operation of the first lifting cylinder 362 and the second lifting cylinder 364, the second tightening shaft 366 can stably approach and align with the installation position on the housing, realizing the smooth installation of the adjusting shaft.

[0047] Reference Figure 12A trigger disc 3661 is fixedly connected to the outer periphery of the second tightening shaft 366, and a sensor 3651 for detecting the number of rotations and angle of the trigger disc 3661 is fixedly connected to the side wall of the mounting platform 365. The sensor 3651 is a photoelectric sensor. The sensor 3651, in conjunction with the trigger disc 3661, can accurately record the number of rotations of the second tightening shaft 366 in real time and send a signal to the control system to ensure that the number of rotations is consistent each time.

[0048] Reference Figure 13 After the adjustment shaft is installed, it is conveyed to the bottom of the limit plate installation mechanism 9. The limit plate installation mechanism 9 includes a limit plate feed channel 91 fixedly connected to the top wall of the workbench 4, a positioning frame 92 fixedly connected to the top wall of the workbench 4, a moving plate 93 slidably connected to the side wall of the positioning frame 92, a lifting plate 94 slidably connected to the side wall of the moving plate 93, a picking cylinder 931 fixedly connected to the top wall of the moving plate 93 for driving the lifting plate 94 to move, and a limit plate gripper 95 fixedly connected to the side wall of the lifting plate 94. A receiving platform 921 is fixedly connected to the side wall of the positioning frame 92. A selection seat 922 is rotatably connected to the top wall of the receiving platform 921. A drive motor 923 for driving the selection seat 922 to rotate is fixedly connected to the bottom wall of the receiving platform 921. The drive motor 923 is a servo motor, which can control the selection seat 922 to adjust the posture and reset of the limit plate. There are two limit plate clamps 95 arranged side by side. One limit plate clamp 95 is used to move the limit plate from the limit plate feed channel 91 to the orientation seat 922, and the other is used to move the limit plate from the orientation seat 922 to the fixture 411 for installation.

[0049] Reference Figure 13 A sensing control device 924 is fixedly connected to the top wall of the receiving platform 921. The sensing control device 924 is a photoelectric sensor. A trigger plate 9221 for triggering the sensing control device 924 is fixedly connected to the side wall of the orientation seat 922. The sensing control device 924 and the trigger plate 9221 cooperate to form a closed-loop control system. The drive motor 923 drives the orientation seat 922, so that the sensing control device 924 senses the trigger plate 9221. At this time, the limit piece has been rotated to a suitable angle. After the limit piece gripper 95 takes out the limit piece, the drive motor 923 resets, so as to perform the next action.

[0050] Reference Figure 5 , Figure 14 The limiting plate fastening mechanism 10 has the same structure as the housing pressing mechanism 7, the difference being that the end of the pressing member 72 is different. The pressing member 72 of the limiting plate fastening mechanism 10 is sleeve-shaped, which facilitates the connection with the adjusting shaft for positioning and pressing the limiting plate down for fastening.

[0051] Reference Figure 15The discharge mechanism 110 includes a first discharge channel 1101, a discharge support plate 1102, a switching cylinder 1103, a second discharge channel 1104, a discharge clamping arm, and a discharge moving unit 1105. The first discharge channel 1101 and the discharge support plate 1102 are both fixedly connected to the top wall of the worktable 4. The switching cylinder 1103 is fixedly connected to the side wall of the discharge support plate 1102, and the output shaft of the switching cylinder 1103 is fixedly connected to the side wall of the second discharge channel 1104. The first discharge channel 1101 is located below the second discharge channel 1104. The switching cylinder 1103 can drive the second discharge channel 1104 to move closer to or further away from the rotary table 41, thereby realizing the switching between the first discharge channel 1101 and the second discharge channel 1104, facilitating the separation of good and defective products. The discharge moving unit 1105 consists of multiple cylinders and a moving track, enabling the discharge clamping arm to move vertically and horizontally. This technology is existing technology and will not be described in detail here.

[0052] Reference Figure 1 , Figure 16 A detection unit 1106 is provided between the discharge mechanism 110 and the limiting plate fastening mechanism 10. The detection unit 1106 includes a seat 1161 fixedly connected to the top wall of the workbench 4, a detection block 1162 slidably connected to the side wall of the seat 1161, a pressing column 1163 passing through and sliding on the detection block 1162, a limiting ring 11631 fixedly connected to the outer periphery of the pressing column 1163, a second proximity switch 1164 fixedly connected to the side wall of the detection block 1162 and directly opposite the limiting ring 11631, and a detection cylinder 1165 for driving the detection block 1162 to move. The end of the pressing column 1163 is sleeve-shaped for the insertion of the adjustment shaft. After the limiting plate is tightened, the detection cylinder 1165 drives the detection block 1162 to press down. The pressing column 1163 is sleeved on the adjusting shaft and abuts against the limiting plate. As the detection block 1162 continues to press down, the pressing column 1163 gradually approaches the second proximity switch 1164. The second proximity switch 1164 detects whether the limiting plate is installed in place. When it is detected that the limiting plate is not installed in place, the second proximity switch 1164 sends a signal, and the switching cylinder 1103 is started, so that the first discharge channel 1101 and the second discharge channel 1104 are switched.

[0053] The implementation principle of the adjusting shaft feeding mechanism and the temperature controller housing assembly machine in this application embodiment is as follows: During housing assembly, the rotary table 41 rotates, driving the fixture 411 to move. The gasket feeding mechanism 5 and the housing feeding mechanism 6 place the gasket and housing on the fixture 411 respectively. Then, the housing and gasket are fastened by the housing clamping mechanism 7. The oil injection mechanism 8 injects oil into the gasket for lubrication. Then, the fixture 411 enters below the adjusting shaft feeding mechanism. The adjusting shaft is arranged through the adjusting shaft feeding channel 11. The gripping unit 13 takes out the adjusting shaft. The mechanical gripper 34 of the conveying unit 3 moves the adjusting shaft to the mounting seat 29 of the rotating disk 21. The rotating disk 21 moves, causing the adjusting shaft to move below the first tightening shaft 26. The lifting platform 23 descends, causing the material to be unloaded. Hole 233 is close to the adjusting shaft. The screw falls from the screw feed hole 2311 into the conveying block 232. The conveying block 232 drives the screw to move and fall from the discharge hole 233. The first tightening shaft 26 passes through the discharge hole 233 to tighten the screw into the adjusting shaft. The rotating disk 21 rotates so that the tightened adjusting shaft enters below the mechanical gripper 34 and is conveyed to the transfer table 28. The second tightening shaft 366 puts the adjusting shaft into the housing and tightens it. Then it enters below the limit plate mounting mechanism 9. After the limit plate is adjusted in direction on the orientation seat 922, it is installed on the adjusting shaft and tightened by the limit plate fastening mechanism 10. After the detection unit 1106 detects whether the limit plate is installed in place, it enters below the discharge mechanism 110 for discharge.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
