Description

Technical Field

[0001] The present invention relates to the technical field of sorting equipment, and in particular to a temperature controller sorting equipment and a sorting method thereof. Background Art

[0002] A snap-action thermostat is a bimetallic thermostat with a casing. Its internal bimetallic contacts will undergo physical changes according to the ambient temperature, thereby producing an effect, such as a series of automatic control actions in which the two terminals of the snap-action thermostat are connected or disconnected. Snap-action thermostats are used in various electric heating products, such as rice cookers, water heaters, air fryers and other home appliances. They are mainly used for temperature adjustment, temperature control and overheating protection of these electric heating products. Among them, the size of the snap-action thermostat varies according to the specific application scenario, such as thin-film thermostats or special-shaped thermostats.

[0003] The production and processing of the snap-action thermostat involves temperature detection and terminal universality detection and sorting. When the thermostat is heated to different temperatures, the temperature sorting equipment is used to sort the connection or disconnection of its terminals, so as to select qualified thermostats.

[0004] In the sorting process of the sudden jump thermostat, the thermostat needs to be transported to different heating fields for heat sorting. For example, the Chinese utility model patent with publication number CN218394806U and patent name "A thermostat sorting machine" discloses a feeding mechanism in which a feeding belt with a discharge port is arranged above the heating plate. The thermostat is in the discharge port of the feeding belt and moves on the heating plate through the feeding belt, thereby transporting the thermostat to each work station for heating sorting.

[0005] Although the feeding belt with a discharge port can transport the temperature controller to each workstation on the heating plate, there are still the following defects:

[0006] 1. The existing method of conveying the thermostat by the feeding belt requires that the thermostat be placed on the heating plate in alignment with the discharge port, and the discharge port of the feeding belt pushes and pushes the thermostat to slide forward, which requires higher feeding accuracy of the thermostat; this feeding belt with a discharge port is only suitable for conveying thermostats with relatively thin thickness (such as thermostats with a thickness of about 2 mm). Since thermostats with thicker or higher heights usually have lighter heads at the upper ends and heavier feet at the lower ends, if this feeding belt is used for conveying, it is easy to tip over or deviate; therefore, the method of conveying thermostats by the feeding belt has a limited scope of application and affects the conveying and heating sorting efficiency of the thermostats.

[0007] 2. Using a feeding belt to transport the thermostat on the heating plate places high demands on the design of the heating plate. For example, the guide trough of the heating plate needs to be designed to be deeper, and a cover plate needs to be added above the heating plate to further stabilize the thermostat. This increases the manufacturing cost of the sorting equipment and the sorting cost of the thermostat. Summary of the invention

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) The thermostat sorting device provided in the embodiment of the present application comprises a first clamping mechanism provided at the loading station for automatically loading the thermostat, and a heating module having a lower action limit zone and an upper action limit zone is provided at the sorting station for providing different heating temperatures for the thermostat on the heating module; a feeding driver drives the fixed material claws of a plurality of pushing mechanisms to descend and push the thermostat along the sorting direction, thereby realizing automatic batch feeding of the thermostat and improving the conveying efficiency of the thermostat; as the thermostat is fed on the heating module, a detection module is provided to detect whether the two terminals of the thermostat on the lower action limit zone and the upper action limit zone are connected, and according to whether the two terminals of the thermostat are connected or disconnected, the second clamping mechanism is controlled to clamp and feed the thermostat to the corresponding hopper;

[0036] Compared with the previous implementation method of using a feeding belt with a discharge port to transport the temperature controller, the material fixing claws of the pushing mechanism in the embodiment of the present application are driven by the feeding driver to descend to the lower end of the temperature controller and push the two sides of the lower end of the temperature controller tightly, which is suitable for pushing temperature controllers of different thicknesses and has a wider range of applications; the material fixing claws descend from top to bottom to push the temperature controller, which can block the rear side of the temperature controller to avoid the problem of the temperature controller tipping backward or shifting during the transportation process, and the transportation stability of the temperature controller is higher; batches of temperature controllers are transported by the material fixing claws of several pushing mechanisms, and the sorting speed is as high as 80 pieces / min or more, which increases the transportation and heating sorting efficiency of the temperature controller by about 30%; and the design requirements for the heating module are lower, and there is no need to add structural parts such as cover plates to the heating module, saving the manufacturing cost of the temperature controller sorting equipment.

[0037] (2) The pushing beam of the pushing mechanism extends along the sorting direction. A plurality of fixing claws are arranged in the length direction of the pushing beam to synchronously push a plurality of temperature controllers on the heating module, so that each pushing beam can push the temperature controllers in batches, thereby further improving the sorting efficiency of the temperature controllers. The pushing beam is movably arranged on the longitudinal feeding slide rail. Driven by the feeding motor, the pushing beam can drive the fixing claws to slide back and forth along the transverse feeding slide rail, thereby achieving the feeding effect in the sorting direction. A feeding cylinder is arranged on the transverse feeding slide rail, which is used to drive the pushing beam and the fixing claws to rise and fall in the vertical direction, thereby achieving the purpose of rising, resetting and descending of the fixing claws. Moreover, the fixing claws are provided with at least two fixing rods extending vertically downward and used to push the rear side of the temperature controller in the sliding direction. The two fixing rods can stably push the rear side of the temperature controller, thereby achieving higher conveying stability and fully automated operation, thereby improving feeding efficiency and quality.

[0038] (3) Before the temperature controller of the vibration disk enters the heating module via the straight vibration track, it is first transported to the angle adjustment mechanism of the feeding system. The loading table of the angle adjustment mechanism is used to carry the temperature controller, and the rotating motor drives the loading table to rotate, thereby adjusting the terminal angle of the temperature controller to correspond to the detection position of the detection module, thereby improving the detection module to align with the terminals of the temperature controller after the temperature controller enters the heating module, thereby improving the detection accuracy of whether the two terminals of the temperature controller are connected.

[0040] (5) The temperature controller sorting method provided in the embodiment of the present application is an automated operation in the loading, sorting and unloading processes. A first clamping mechanism is used at the loading station to automatically clamp and feed the temperature controller to be sorted, thereby improving the loading efficiency and accuracy. At the sorting station, a feeding driver drives a pushing mechanism to automatically push several temperature controllers on the heating module to each heating area, thereby ensuring that each temperature controller accurately reaches the heating area and the detection area, thereby improving the heating accuracy and detection accuracy of the temperature controller. At the unloading station, a second clamping mechanism is used to automatically clamp and feed the temperature controller after heating and detection, and the second clamping mechanism can clamp and feed the temperature controller to the corresponding hopper according to the detection feedback signal of the temperature controller in each heating area.

[0055] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0056] like Figure 1-7As shown, the embodiment of the present application provides a thermostat sorting device, which is used for heating and sorting the action lower limit, action upper limit, reset upper limit, and reset lower limit of the finished product of the jump-type thermostat a, so as to sort out qualified products. The thermostat a sorting device has a control cabinet 50 for installing a control system, a workbench 40 is arranged on the control cabinet 50, and a loading station 10, a sorting station 20, and a unloading station 30 are sequentially arranged on the workbench 40 along the sorting direction.

[0057] More specifically, the loading station 10 is provided with a loading system 11 , the sorting station 20 is provided with a feeding system 21 and a detection system 22 , and the unloading station 30 is provided with a unloading system 31 .

[0058] Among them, the feeding system 11 has a first clamping mechanism 115, the number of the first clamping mechanisms 115 can be increased or decreased according to actual usage requirements. The first clamping mechanism 115 preferably uses a robot. A vertically arranged feeding bracket 113 is installed on the feeding side of the detection system 22 and the workbench 40, and the upper end of the feeding bracket 113 is provided with a first clamping slide rail 114 extending along the sorting direction.

[0059] The first clamping mechanism 115 is movably arranged on the first clamping rail 114 through a slide seat, and the slide seat is also provided with a first clamping cylinder 116 and a first lifting rail 118, and the first clamping cylinder 116 at least includes a cylinder for driving the first clamping mechanism 115 to slide back and forth in the direction of the first clamping rail 114, a cylinder for driving the first clamping mechanism 115 to rise and fall in the direction of the first lifting rail 118, and a cylinder for controlling the first clamping mechanism 115 to clamp the temperature controller a. Therefore, driven by the first clamping cylinder 116, the first clamping mechanism 115 can slide along the first clamping rail 114 to the sorting station 20 and clamp the temperature controller a to the detection system 22 of the sorting station 20.

[0060] The feeding system 21 has a feeding drive and a pushing mechanism 214. The feeding drive is used to drive the pushing mechanism 214 to rise and fall in the vertical direction. For example, when the pushing mechanism 214 descends to the heating module 220, the feeding drive can drive the pushing mechanism 214 to slide along the sorting direction and push several temperature controllers a on the heating module 220 in sequence along the sorting direction.

[0061] The detection system 22 has a plurality of heating modules 220 and detection modules 221, wherein the heating module 220 has a heating plate 2201 and a heating tube 2202 providing a heat source for the heating plate 2201. A plurality of heating plates 2201 can be arranged in parallel according to sorting requirements. Each heating plate 2201 extends along the sorting direction, and a plurality of heating tubes 2202 providing different amounts of heat are arranged along the length direction of the heating plate 2201.

[0062] The heating plate 2201 is provided with a preheating zone 2203, an action lower limit zone 2204, an action upper limit zone 2205, a reset upper limit zone and a reset lower limit zone along the sorting direction. Therefore, the temperature controller a can be pushed to the preheating zone 2203, the action lower limit zone 2204, the action upper limit zone 2205, the reset upper limit zone and the reset lower limit zone in sequence along the heating plate 2201 through the pushing mechanism 214, and different temperature heating and sorting are performed. The operating temperature range of the heating zone provided in the embodiment of the present application is 45°C-220°C, and the specific temperature setting of each heating zone can be adjusted according to the actual working requirements, which will not be described in detail here. The above-mentioned reset upper limit zone and reset lower limit zone can be omitted as non-essential heating and sorting zones.

[0063] The detection module 221 at least has a lower limit detection member 2210 and an upper limit detection member 2211, both of which are provided with a base 22110, an elastic pressure rod 22111 and a probe 22112, the base 22110 is fixed on the pushing mechanism 214, the elastic pressure rod 22111 and the probe 22112 are vertically penetrated on the base 22110, two probes 22112 are provided, and the elastic pressure rod 22111 is provided between the two probes 22112. Among them, the lower limit detection member 2210 is provided at the discharge end of the lower limit area 2204, and the upper limit detection member 2211 is provided at the discharge end of the upper limit area 2205.

[0064] The unloading system 31 has a second clamping mechanism 311, and the number of the second clamping mechanisms 311 can be increased or decreased according to actual usage requirements. The second clamping mechanism 311 preferably uses a robot. A vertically arranged unloading bracket is installed on the discharge side of the detection system 22 and the workbench 40, and the upper end of the unloading bracket is provided with a second clamping slide rail 310 extending along the sorting direction.

[0065] Moreover, the second clamping slide rail 310 is extended along the sorting direction and is located above the hopper. A feeding motor 317 is provided on the second clamping slide rail 310. The second clamping mechanism 311 is movably provided on the second clamping slide rail 310 through a slide seat. The slide seat is also provided with a second clamping cylinder 318 and a second lifting slide rail 319. The feeding motor 317 is used to connect the slide seat on which the second clamping mechanism 311, the second clamping cylinder 318 and the second lifting slide rail 319 are installed, and drive the slide seat to slide back and forth along the direction of the second clamping slide rail 310.

[0066] The second clamping cylinder 318 at least includes a cylinder for driving the second clamping mechanism 311 to rise and fall in the direction of the second lifting slide rail 319 and a cylinder for controlling the second clamping mechanism 311 to clamp the thermostat a. Therefore, driven by the unloading motor 317 and the second clamping cylinder 318, the second clamping mechanism 311 can clamp and deliver the thermostat a to the corresponding hopper along the track direction of the second clamping slide rail 310 and the second lifting slide rail 319.

[0067] The hoppers provided in the unloading system 31 include a reset upper limit hopper 312, a reset lower limit hopper 313, an action lower limit hopper 314, an action upper limit hopper 315 and a qualified product hopper 316 which are sequentially provided along the sorting direction. Among them, the reset upper limit hopper 312 and the reset lower limit hopper 313 are considered to be put into use only when the reset upper limit area and the reset lower limit area are set on the heating plate 2201 and the reset upper and lower limits of the corresponding detection thermostat a are detected.

[0068] Therefore, the unloading system 31 sequentially sets the reset upper limit hopper 312, the reset lower limit hopper 313, the action lower limit hopper 314, the action upper limit hopper 315 and the qualified product hopper 316 along the sorting direction. The second clamping mechanism 311 sets the direction of the second clamping slide rail 310 and according to the detection feedback signal of the temperature controller a in each heating area by the detection module 221, the temperature controller a after the heating detection is clamped and sent to the corresponding hopper, thereby replacing manual unloading, avoiding human error in operation, reducing labor intensity, and improving unloading efficiency and accuracy.

[0069] During the detection of temperature controller a, the feeding driver drives the pushing mechanism 214 to descend vertically and simultaneously drives the base 22110 to descend. The top of the temperature controller a is first pressed by the elastic pressure rod 22111, and then the two terminals of the temperature controller a are correspondingly detected to be connected or disconnected through two probes 22112.

[0070] Therefore, the action lower limit detection member 2210 detects the thermostat a that enters the action lower limit zone 2204 after being preheated in the preheating zone 2203. The action lower limit detection member 2210 will detect the thermostat a that is disconnected due to low temperature heating, and feed back the lower limit detection signal to the second clamping mechanism 311, and clamp the thermostat a to the action lower limit hopper 314 without further detection by the action upper limit detection member 2211. If the thermostat a that is connected to the two terminals due to low temperature heating is detected, the corresponding signal is fed back to the feeding driver, so that the feeding driver drives the pushing mechanism 214 to push the thermostat a to the action upper limit zone 2205 for detection.

[0071] Then, the upper limit detection part 2211 detects the thermostat a after the lower limit detection. The upper limit detection part 2211 will detect the thermostat a that is still connected to the two terminals when it is heated at high temperature, and feedback the upper limit detection signal to the second clamping mechanism 311, and the thermostat a is clamped to the upper limit hopper 315. If the thermostat a is detected to be disconnected from the two terminals when it is heated at high temperature, the corresponding signal is fed back to the second clamping mechanism 311, and the thermostat a is clamped to the qualified product hopper 316. If reset detection is required, it enters the corresponding reset detection area for heating detection.

[0072] In the above detection process of the thermostat a, the discharge end of the action lower limit area 2204 and the discharge end of the action upper limit area 2205 are provided with detection position sensors, and the position signal of the thermostat a is fed back to the action lower limit detection member 2210 and the action upper limit detection member 2211 through the detection position sensor. The end of the heating plate 2201 is also provided with a detection position sensor, which is used to obtain the position of the thermostat a reaching the end of the heating plate 2201 after detection, and feed back the position signal of the thermostat a to the second clamping mechanism 311, so that the second clamping mechanism 311 can timely clamp and deliver the thermostat a to each hopper.

[0073] In this way, the temperature controller a sorting equipment provided in the embodiment of the present application has a first clamping mechanism 115 set at the loading station 10 for automatically loading the temperature controller a, and a heating module 220 with an action lower limit area 2204 and an action upper limit area 2205 is set on the sorting station 20, which is used to provide different heating temperatures for the temperature controller a on the heating module 220; the fixing claws 2141 of the pushing mechanisms 214 are driven to descend and push the temperature controller a along the sorting direction by the feeding driver, thereby realizing the automatic batch feeding of the temperature controller a, and along the feeding process of the temperature controller a on the heating module 220, the detection module 221 is set at the same time to detect whether the two terminals of the temperature controller a on the action lower limit area 2204 and the action upper limit area 2205 are connected or disconnected, and according to the connection or disconnection of the two terminals of the temperature controller a, the second clamping mechanism 311 is controlled to clamp the temperature controller a to the corresponding hopper.

[0074] Compared with the previous implementation method of using a feeding belt with a discharge port to transport the temperature controller a, the material fixing claw 2141 of the pushing mechanism 214 of the embodiment of the present application is driven by the feeding driver to descend to the lower end of the temperature controller a, and pushes the two sides of the lower end of the temperature controller a tightly, which is suitable for pushing thermostats a of different thicknesses and has a wider range of applications; the material fixing claw descends from top to bottom to push the thermostat a, which can block the rear side of the thermostat a to avoid the problem of the thermostat a tipping over or shifting backwards during the transportation process, and the transportation stability of the thermostat a is higher. The batches of thermostats a are transported by the material fixing claws 2141 of several pushing mechanisms 214, and the sorting speed is as high as 80 pieces / min or more, which increases the transportation and heating sorting efficiency of the thermostat a by about 30%; and the design requirements for the heating module 220 are lower, and there is no need to add structural parts such as a cover plate to the heating module 220, saving the manufacturing cost of the thermostat sorting equipment.

[0075] The feeding system 11 is further described. The feeding system 11 includes a vibration plate 110, a direct vibration track 111 and an angle adjustment mechanism 112. The vibration plate 110, the direct vibration track 111 and the angle adjustment mechanism 112 are all arranged on the workbench 40. A number of vibration plates 110 can be arranged according to the use requirements. The number of direct vibration tracks 111 and the angle adjustment mechanism 112 arranged corresponds to the number of vibration plates 110. The direct vibration track 111 is arranged between the vibration plate 110 and the angle adjustment mechanism 112. Therefore, the temperature controller a of the vibration plate 110 is vibrated to the angle adjustment mechanism 112 through the direct vibration track 111, and the terminal angle of the temperature controller a is adjusted by the angle adjustment mechanism 112.

[0076] In addition, the angle adjustment mechanism 112 is arranged on the feeding side of the heating module 220, and the angle adjustment mechanism 112 has a stage and a rotating motor 1121. The stage and the direct vibration track 111 are arranged at the same feeding plane height, and the stage is connected to the output end of the rotating motor 1121. When the thermostat a is vibrated onto the stage via the direct vibration track 111, the rotating motor 1121 drives the stage to rotate, and then the terminal angle of the thermostat a is adjusted to correspond to the detection position of the detection module 221. The first clamping mechanism 115 clamps the thermostat a adjusted by the angle adjustment mechanism 112 to the heating module 220 for heating, and the detection module 221 accurately detects whether the two terminals of the thermostat a are connected or disconnected.

[0077] In order to ensure the smooth progress of the automated loading process, a loading position sensor 117 is provided at the end of the direct vibration track 111, which is used to detect when the thermostat a reaches the end of the direct vibration track 111, and to feedback the position signal to the angle adjustment mechanism 112 to prepare for rotation, and adjust the terminal placement angle of the thermostat a. A loading position sensor 117 is also provided at the position of the angle adjustment mechanism 112, which is used to detect the thermostat a adjusting the terminal angle, and then feedback the signal to the first clamping mechanism 115, so that the thermostat a with the adjusted terminal angle is clamped and sent to the heating plate 2201.

[0078] In this way, before the temperature controller a of the vibration disk 110 enters the heating module 220 through the direct vibration track 111, it is first transported to the angle adjustment mechanism 112 of the feeding system 11. The loading platform of the angle adjustment mechanism 112 is used to carry the temperature controller a, and the rotating motor 1121 drives the loading platform to rotate, thereby adjusting the terminal angle of the temperature controller a to correspond to the detection position of the detection module 221, thereby improving the detection module 221 after the temperature controller a enters the heating module 220, so as to improve the detection accuracy of the connection or disconnection of the two terminals of the temperature controller a.

[0079] The feeding system 21 is further described as comprising a transverse feeding rail 210 and a longitudinal feeding rail 211 , a feeding drive comprising a feeding motor 212 and a feeding cylinder 213 , and a pushing mechanism 214 comprising a pushing beam 2140 and a fixing claw 2141 arranged on the pushing beam 2140 .

The feeding motor 212 drives the slide seat to drive the feeding cylinder 213 and the longitudinal feeding slide 211 to slide back and forth along the direction of the transverse feeding slide 210.

[0081] The pushing beam 2140 is movably arranged on the longitudinal feeding rail 211 through a sliding seat and is located above the heating plate 2201. The pushing beam 2140 also extends along the sorting direction and is parallel to the heating plate 2201. Therefore, under the drive of the feeding motor 212, the pushing beam 2140 can follow the longitudinal feeding rail 211 and slide back and forth along the sorting direction.

[0082] The output rod of the feeding cylinder 213 is fixedly connected to the slide seat on which the push beam 2140 is installed. Therefore, under the drive of the feeding cylinder 213, the push beam 2140 can be lifted and lowered along the longitudinal feeding slide rail 211, thereby realizing the motion control of the push beam 2140 in the sorting direction and the vertical direction.

[0083] The material fixing claw 2141 is arranged on one side or the bottom of the material pushing beam 2140, and a plurality of material fixing claws 2141 are arranged along the length direction of the material pushing beam 2140.

When the fixing claw 2141 follows the pushing beam 2140 to descend to the heating plate 2201, the two fixing rods 21411 on the same corner of the bottom plate 21410 both push the rear side of the temperature controller a in the sliding direction. By pushing the rear side of the temperature controller a in the sliding direction, the stability of the temperature controller a can be maintained during sliding, and the temperature controller a can slide along the sorting direction on the heating plate 2201 under the pushing action of the fixing rods 21411 of the fixing claw 2141.

[0085] Moreover, a feeding position sensor is provided on the bottom plate 21410 for detecting when the thermostat a is pushed to the designated position, and feeding back a signal to the detection system 22, thereby triggering the detection system 22 to perform heating detection on the thermostat a that has reached the designated position.

[0086] In this way, the pushing beam 2140 provided with the pushing mechanism 214 extends along the sorting direction, and a plurality of fixing claws 2141 are provided in the length direction of the pushing beam 2140 to synchronously push a plurality of thermostats a on the heating module 220, so that each pushing beam 2140 can push the thermostats a in batches, thereby further improving the sorting efficiency of the thermostats a; the pushing beam 2140 is movably provided on the longitudinal feeding slide rail 211, and under the drive of the feeding motor 212, the pushing beam 2140 can drive the fixing claws 2141 to move along the transverse feeding slide rail 21 0 reciprocating sliding, to achieve the feeding effect in the sorting direction; a feeding cylinder 213 is arranged on the horizontal feeding slide rail 210, for driving the pushing beam 2140 and driving the fixing claw 2141 to rise and fall in the vertical direction, so as to achieve the purpose of rising and resetting and descending and pushing of the fixing claw 2141; and the fixing claw 2141 is provided with at least two fixing rods 21411 extending vertically downward and used for pushing the rear side of the temperature controller a in the sliding direction. The two fixing rods 21411 can stably push the rear side of the temperature controller a, so that the conveying stability is higher, the whole process is automated, and the feeding efficiency and quality are improved.
