Description

Technical Field

[0002] A thermostat, as a core device for temperature control, is widely used in multiple fields such as household appliances, industrial equipment, and HVAC systems. Its core function is to automatically adjust heating or cooling equipment according to a preset temperature value to maintain the stability of the ambient or equipment temperature.

[0003] In order to adapt to different installation environments, a fixing plate is usually welded to the bimetal component of the thermostat to enhance the stability and safety of installation. However, although this design has its advantages, there are also certain problems. Especially during the welding process, to ensure stability, a high-density support plate needs to be placed at the lower end of the fixing plate. However, due to poor heat dissipation of the support plate, it is easy to cause overheating of the welding area, which in turn causes deformation of the fixing plate or the bimetal component.

[0050] The support plate 422 is divided into a limiting section and a connecting section, wherein the connecting section and the limiting section are fixedly connected by a 匚-shaped connecting block with an opening facing upward, and telescopic sleeves fixedly connected to the supporting plate 423 are arranged at the four corners of the upper end surface of the connecting section.

[0051] There are two conveying device bodies 1, which are used for conveying the fixed plate and the bimetallic component respectively. The two conveying device bodies 1 for conveying the fixed plate and the bimetallic component are placed at a 90-degree position, and the mounting frame 31 is fixedly arranged above the corresponding conveying device body 1.

[0052] The driving group 32 includes two bevel gears 321 that are meshed and rotatably connected to the inner wall of the mounting frame 31 through shafts. The outer wall of one of the shafts is fixedly connected to a pulley, and the pulley is connected to the conveying equipment body 1 through a flat belt transmission. The end of the other shaft is fixedly provided with a bidirectional screw rod 322 that is rotatably connected to the inner wall of the mounting frame 31, and the outer wall of the bidirectional screw rod 322 is cooperated with a linkage block 323.

[0053] The adjustment group 33 includes a trapezoidal plate 331 fixedly connected to the linkage block 323, and sliding grooves are respectively provided on the two inclined sides of the trapezoidal plate 331, and trapezoidal matching platforms 332 are fixedly provided on the left and right side walls of the trapezoidal plate 331. A mounting plate 333 is fixedly provided inside the mounting frame 31 and below the trapezoidal plate 331, and an adjusting piece 334 is provided on the mounting plate 333 for cooperating with the trapezoidal plate 331 and adjusting the position of the fixed plate. Wedge-shaped platforms 335 matching the inclined surfaces of the trapezoidal matching platforms 332 are symmetrically provided on the left and right sides of the adjusting piece 334, and a strip plate 336 whose lower end surface is slidably connected to the conveying equipment body 1 is hingedly provided on the side wall of the wedge-shaped platform 335 through an L-shaped rod.

[0054] The adjusting member 334 includes two adjusting rods 3341 which always slide inside the sliding groove through rollers and whose lower end surfaces slide through the mounting plate 333. The outer wall spring of the adjusting rod 3341 is fixedly connected to the mounting plate 333, and a rectangular plate 3342 with sliding grooves symmetrically opened along the left and right directions is fixedly provided on the lower end surface of the adjusting rod 3341.

[0055] The flipping group 53 includes a support disk 531 fixedly arranged on the upper end surface of the support platform 51. At the central position of a side wall of the support disk 531 close to the mounting disk 421, a rotating boss 532 with arc-shaped grooves correspondingly formed in the end face at positions corresponding to the support plate 422 and the supporting plate 423 is rotatably arranged. Electromagnets are mounted on the upper and lower side walls of both arc-shaped grooves. The other end of the rotating boss 532 rotatably penetrates through the support disk 531 and is fixedly connected to a gear 533.

[0056] The positioning group 21 includes a square plate 211 fixedly arranged at the welding end of the welding equipment body 2. Two welding heads are arranged at the central position of the lower end surface of the square plate 211 through mounting columns. Four conical positioning rods 212 are fixedly arranged on the lower end surface of the square plate 211 and on the circumferential outer wall of the mounting columns.

[0057] Transportation and position adjustment of the fixing plate and the bimetallic component:

[0058] During actual use, start the corresponding two conveying equipment bodies 1. The two conveying equipment bodies 1 synchronously convey the fixing plate and the bimetallic component to the supporting part 42. Both of the two conveying equipment bodies 1 adopt electric drive, and multiple groups of conveying rollers are arranged thereon, which can effectively reduce the distance between adjacent conveying rollers, thereby improving the stability of the conveying work.

[0059] With the continuous operation of the conveying equipment body 1, any one of the conveying rollers drives one of the bevel gears 321 to rotate synchronously through a flat belt, and the other bevel gear 321 rotates synchronously after being engaged. During this process, the bidirectional lead screw 322 fixedly connected to the end of the bevel gear 321 also rotates synchronously under the drive of the bevel gear 321. When the fixing plate moves, it preferentially enters the mounting frame 31. The linkage block 323 drives the trapezoidal plate 331 to perform a reciprocating linear motion under the continuous self-rotation of the bidirectional lead screw 322. When the trapezoidal plate 331 is driven by the linkage block 323 and moves forward, since the sliding groove on the horizontal section of the lower end surface of the trapezoidal plate 331 gradually disengages from the roller on the rear-side adjusting rod 3341, the adjusting rod 3341 gradually resets upward under the action of the spring and drives the lower rectangular plate 3342 to move away from the conveying equipment body 1. When the adjusting rod 3341 drives the rectangular plate 3342 to move upward, it gradually creates a moving space and enables the fixing plate to smoothly travel along the conveying rollers.

[0060] During the process of the trapezoidal plate 331 being driven forward by the linkage block 323, the sliding groove on the horizontal section of the trapezoidal plate 331 gradually moves forward and cooperates with and pushes against the roller on the front-side adjusting rod 3341, thereby causing the front-side adjusting rod 3341 to drive the rectangular plate 3342 provided thereon to gradually move downward. During the downward movement of the rectangular plate 3342, the two inverted L-shaped sliders 3343 sliding inside its chute move downward synchronously. During this process, the trapezoidal mating platforms 332 provided on the left and right side walls of the trapezoidal plate 331 gradually come into contact with the wedge-shaped platforms 335 during the movement of the trapezoidal plate 331. As the trapezoidal plate 331 continues to move forward, the trapezoidal mating platforms 332 will respectively push the two wedge-shaped platforms 335 toward the left and right sides. At this time, the strip-shaped plates 336 below the two wedge-shaped platforms 335 are respectively pushed by the L-shaped rods hinged thereto. Under the pushing force of the L-shaped rods, the two strip-shaped plates 336 approach each other and respectively push the push rods 3344 on the same side. After being pushed, the inverted L-shaped sliders 3343 that are symmetric about the left and right are close to each other synchronously. Finally, the two vertical sections of the inverted L-shaped sliders 3343 complete the further adjustment of the position of the fixed plate.

[0061] Meanwhile, when the bimetallic component moves to the top of the corresponding conveying equipment body 1, the outermost bimetallic component is pushed along the waist slot on the support plate 422 through an external pusher mechanism. Since the diameter of the waist slot opened on the support plate 422 is smaller than the diameter of the cover of the bimetallic component, the bimetallic component will not fall after being pushed into the waist slot. Continuing to push the bimetallic component, at this time, the two V-shaped clamping blocks 4221 inside the cavity of the limiting section of the support plate 422 rotate under the thrust and squeeze the tension spring (in the initial state, the mating section of the V-shaped clamping block 4221 away from the opening side of the waist slot is located outside the cavity, while the clamping section of the V-shaped clamping block 4221 is initially located inside the cavity of the support plate 422. When the bimetallic component enters along the waist slot, the mating section is pushed by the outer wall of the bimetallic component, causing the mating section to rotate around the connection point between the mating section and the clamping section. At this time, the mating section moves into the cavity of the support plate 422, and the clamping section moves to the outer wall of the cavity of the support plate 422 and fits with the outer wall of the bimetallic component). Finally, the electromagnets on the upper and lower side walls of the V-shaped clamping plate are turned on, thus completing the clamping and limiting work of the bimetallic component.

[0062] It should be noted that in the initial state, since the telescopic sleeve between the supporting plate 423 and the support plate 422 is not compressed, there is a certain gap between the supporting plate 423 and the support plate 422. When the two conveying equipment bodies 1 respectively convey the fixed plate and the bimetallic component, the synchronization of the feeding of the fixed plate and the bimetallic component can be realized through the gap between the supporting plate 423 and the support plate 422, reducing the time spent on feeding the fixed plate and the bimetallic component in the early stage, and then slightly improving the forming and welding work efficiency.

[0063] Forming and welding work of the fixed plate and the bimetallic component:

[0064] After the fixing plate and the bimetallic component are respectively placed on the support plate 422 and the supporting plate 423, the control welding equipment body 2 drives the square plate 211 and the conical positioning rod 212 to rotate to the directly above the fixing plate, and then controls the welding head to move downward (when in the initial position, when the two welding heads in the middle of the square plate 211 are not performing welding work, their lengths are less than the lengths of the four conical positioning rods 212). The two conical positioning rods 212 corresponding to the front and back directions of the supporting plate 423 preferentially pass through the fixing plate. Since the diameter of the conical positioning rod 212 gradually increases from bottom to top, when the conical positioning rod 212 passes through the fixing plate and the supporting plate 423, the secondary alignment work of the fixing plate is realized through the outer walls with diameter changes of the two conical positioning rods 212 (during the downward movement of the conical positioning rod 212, the end with the smaller diameter will preferentially enter the holes on both sides of the fixing plate. As the conical positioning rod 212 gradually moves downward, the inner expansion of the holes of the fixing plate is realized through its outer wall with the larger diameter). The conical positioning rods can not only ensure the smooth progress of the positioning work, but also the synchronous movement of the two conical positioning rods 212 can ensure that the central hole of the fixing plate is concentric and coaxial with the mounting column, thereby improving the later welding quality and avoiding the phenomenon of false soldering and missed soldering caused by the non-concentricity of the fixing plate and the welding head.

[0065] As the two conical positioning rods 212 continue to move downward, after their lower end surfaces contact the return plate 4243, they push the return plate 4243 downward. At this time, the return plate 4243 and the supporting plate 423 move away from each other, and the four hinge rods arranged on the return plate 4243 respectively pull the corresponding adjusting plates 4242 downward. After being pulled, the adjusting plates 4242 change from the initial horizontal state to an inclined state. As the return plate 4243 continues to move downward, to compensate for the distance between the return plate 4243 and the adjusting plates 4242, at this time, the arc-shaped top plate 4241 slides and moves into the sliding groove (in the initial state, the four arc-shaped top plates 4241 all penetrate the supporting plate 423 and are located on the inner wall of the middle through hole. When the four arc-shaped top plates 4241 move away synchronously, the lower bimetallic component will gradually pass through the through hole in the middle of the supporting plate 423 due to the lack of obstruction, and the outer wall of the bimetallic component will be attached to the inner wall of the central hole of the fixing plate).

[0066] At the same time, the other two relatively positioned conical positioning rods 212 respectively push the corresponding two T-shaped pressing blocks 42323 during the downward movement. When the two T-shaped pressing blocks 42323 move downward, they stretch the springs and move to the bottom end of the C-shaped adjusting frame 42321, and then the power supply of the electromagnet is turned on, so that the two T-shaped pressing blocks 42323 are electromagnetically fixed to the C-shaped adjusting frame 42321 respectively. The upper surface of the fixing plate is limited by the two T-shaped pressing blocks 42323, which improves the stability of the fixing plate on the supporting plate 423 and avoids the vibration of the fixing plate caused by external forces during the later welding process.

[0067] Finally, control the two welding heads to extend synchronously to complete the welding work at the connection between the fixed plate and the bimetallic component.

[0068] It should be noted that a U-shaped adjusting frame 42321 is fixedly arranged on the upper end surface of the supporting plate 423. Two guide plates with opposite inclination directions are fixedly arranged at the opening of the U-shaped adjusting frame 42321. After the fixed plate completes the position adjustment and enters the supporting plate 423, the position adjustment of the fixed plate is further completed through the two inclined guide plates. The non-opening end of the U-shaped adjusting frame 42321 will block the fixed plate, so as to ensure that the fixed plate cannot continue to move forward after moving to the specified position, thus making the position of the fixed plate consistent during each welding.

[0069] There is a certain height difference between the arc-shaped top plate 4241 and the adjusting plate 4242. When the arc-shaped top plate 4241 is pulled into the supporting plate 423 and the connection between the fixed plate and the bimetallic component is welded, the excess heat will be discharged through a number of heat dissipation holes 4231 opened on the supporting plate 423, avoiding the deformation of the fixed plate or the bimetallic component caused by local overheating of the welding point. At the same time, the welding sparks will be intercepted by the arc-shaped top plate 4241 after entering the heat dissipation holes 4231, preventing the sparks from directly falling down due to gravity and adhering to the outer surface of the bimetallic component.

[0070] Welding work on the reverse side of the fixed plate and the bimetallic component:

[0071] After the welding head completes the single-sided welding work of the fixed plate and the bimetallic component, first control the welding equipment body 2 to drive the square plate 211 and the conical positioning rod 212 to move away from the fixed plate and the bimetallic component. After the conical positioning rod 212 is separated from the supporting plate 423, the supporting plate 423 lacking downward pressure is reset upward under the resilience of the telescopic sleeve. Since the fixed plate and the bimetallic component have completed the single-sided welding and are connected as a whole, the bimetallic component will not fall downward into the waist groove of the supporting plate 422 after the conical positioning rod 212 is separated.

[0072] Subsequently, an external stepping motor drives the bearing tray 41 to rotate by ninety degrees. The fixed plate for single-sided welding and the bimetallic component move inside the rotating boss 532 driven by the supporting plate 423 and the supporting board 422. Then, the electromagnets on the upper and lower sidewalls of the rotating boss 532 are activated, causing the rotating boss 532 to be electromagnetically fixed to the supporting board 422 and the supporting plate 423. Next, the external driving device is controlled to engage the gear 533 to rotate. During the rotation of the gear 533, it synchronously drives the rotating boss 532, the supporting plate 423, and the supporting board 422 to rotate. When the mounting plate 421 rotates, the volute spring inside it is compressed. Since the T-shaped pressing block 42323 always fits against the upper surface of the fixed plate, the fixed plate and the bimetallic component will not slide down due to gravity during the rotation. When the fixed plate and the bimetallic component rotate by one hundred and eighty degrees, the power supply of the electromagnets on the two T-shaped pressing blocks 42323 is disconnected. At this time, the fixed plate and the bimetallic component will fall to the lower support table 51 due to gravity due to the lack of support. Immediately after disconnecting the power supply of the electromagnet on the rotating boss 532, the stepping motor is started to drive the mounting plate 421 to rotate. When the mounting plate 421 disengages from the rotating boss 532, the volute spring inside it resets and drives the mounting plate 421 to rotate back.

[0073] After the mounting plate 421 drives the supporting board 422 and the supporting plate 423 to rotate and move, the obstruction on the upper end surfaces of the fixed plate and the bimetallic component disappears. At this time, the welding equipment body 2 is controlled to drive the welding head to rotate to directly above the fixed plate, and the welding head completes the welding work on the reverse connection points of the fixed plate and the bimetallic component. Finally, the welded fixed plate assembly is lifted upward by an external ejector device and collected into an external storage bin.

[0074] It is worth emphasizing that this forming and welding equipment mainly has the following advantages:

[0075] Advantage 1: There is a certain height difference between the arc-shaped top plate 4241 and the adjusting plate 4242. When the arc-shaped top plate 4241 is pulled into the supporting plate 423 and the connection between the fixed plate and the bimetallic component is welded, the excess heat will be discharged through a number of heat dissipation holes 4231 opened on the supporting plate 423, avoiding deformation of the fixed plate or the bimetallic component caused by local overheating of the welding point. At the same time, the welding sparks will be intercepted by the arc-shaped top plate 4241 after entering the heat dissipation holes 4231, preventing the sparks from directly falling due to gravity and adhering to the outer surface of the bimetallic component.

[0076] Advantage 2: The supporting plate 423 and the supporting board 422 are connected by a telescopic sleeve. Through the interval between the supporting plate 423 and the supporting board 422, the synchronous feeding of the fixed plate and the bimetallic component is realized, reducing the previous feeding time, thereby slightly improving the forming and welding work efficiency.

[0077] Advantage 3: During the downward movement of the conical positioning rod 212, the end with a smaller diameter will enter the holes on both sides of the fixing plate first. As the conical positioning rod 212 gradually moves downward, the inner diameter of the holes in the fixing plate is expanded by its outer wall with a larger diameter. The conical positioning rod can not only ensure the smooth progress of the positioning work, but also the synchronous movement of the two conical positioning rods 212 can ensure that the central hole of the fixing plate is concentric and coaxial with the mounting post, thereby improving the welding quality in the later stage and avoiding the phenomenon of false soldering and missed soldering caused by the non-concentricity between the fixing plate and the welding head.

[0078] Advantage 4: As the trapezoidal plate 331 continues to move forward, the trapezoidal mating table 332 will push the two wedge-shaped tables 335 towards the left and right sides respectively. At this time, the strip-shaped plates 336 below the two wedge-shaped tables 335 are respectively pushed by the L-shaped rods hinged to them. Under the pushing force of the L-shaped rods, the two strip-shaped plates 336 approach each other and respectively push the abutting rods 3344 on the same side. After being pushed, the two abutting rods 3344 move closer synchronously with the inverted L-shaped sliders 3343 that are symmetric about the left and right. Finally, the two vertical segments of the inverted L-shaped sliders 3343 complete the adjustment of the position of the fixing plate, ensuring the stability of the position of the fixing plate during transportation. At the same time, by the outer wall of the bimetallic component pushing against the mating section, the mating section rotates around the connection point between the mating section and the clamping section, and the clamping section moves to the outer wall of the cavity of the support plate 422 and fits with the outer wall of the bimetallic component to complete the clamping and limiting work of the bimetallic component. Through the limiting work of the clamping section, the relative position between the bimetallic component and the fixing plate is ensured, laying a foundation for the coordinated movement of the fixing plate and the bimetallic component in the later stage.
