Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to a thermostat sorting machine. Background Art

[0002] Among the types of thermostats, the snap-action thermostat is a bimetal thermostat with a housing. According to the change of ambient temperature, physical changes occur inside its own switch, thus generating effects, such as a series of automatic control actions in which the two terminals of the thermostat are connected or disconnected. The thermostat is applied to various electric heating products, such as home appliances like rice cookers, water heaters, air fryers, etc. The thermostat is used for temperature regulation, temperature control and overheat protection of these electric heating products.

[0003] In the production and processing process of the snap-action thermostat, there are production processes related to temperature detection and terminal universality detection and sorting. Usually, a temperature sorting device is used to perform temperature sorting on the heat change action of the thermostat itself, so as to select the thermostat at the appropriate temperature stage. In the prior art, mainly a multi-section hot oven is used to heat and sort the thermostat. A single-channel chain is arranged corresponding to the oven, and a jig for placing the thermostat is provided on the chain, and the thermostat is transported to each station for heating and sorting.

[0004] Although the traditional hot oven can perform basic heating and sorting work on the thermostat, there are still the following defects:

[0005] 1. When the hot oven uses a chain and a jig to transport the thermostat, each jig can only accommodate and transport one thermostat, and the transport efficiency is relatively low, which cannot meet the production efficiency requirements.

[0006] 2. The jig of the hot oven will cause heat obstruction to the thermostat, affecting the heat receiving effect and heat receiving accuracy of the thermostat; moreover, the heating uniformity of the hot oven is ±1°C, with a large fuel consumption, high energy consumption, less environmental protection, and increased costs.

[0007] 3. When using a hot oven to heat the thermostat, it is necessary to manually use clamping tools such as pliers to load and unload each thermostat one by one. Manual operation is prone to problems such as wrong material feeding, missing material feeding, and incorrect placement during loading, which affect the sorting efficiency and quality of the thermostat.

[0025] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0026] (1) The thermostat sorter provided by the embodiment of the present application has a first clamping mechanism arranged at the loading station for automatically loading the thermostat. A heating module with several heating zones is arranged at the sorting station, which is used to provide different heating temperatures for the thermostats reaching different heating zones on the heating module; the pusher carrier of the pusher mechanism is driven by a feeding driver to realize the automatic feeding of the thermostat. As the feeding process of the thermostat on the heating module progresses, a detection module is simultaneously set to detect whether the two terminals of the thermostat on each heating zone are connected or disconnected; the second clamping mechanism of the discharging system clamps the thermostat into the corresponding hopper according to the detection signal fed back by the detection module;

[0027] Compared with the prior implementation means of using the chain and fixture of the thermal oven to convey and heat the thermostat, the sorting work of the thermostat in the embodiment of the present application is fully automated without manual intervention, avoiding problems such as misfeeding, missing feeding, and incorrect loading and placement of the thermostat by manual operation, and improving the sorting quality of the thermostat; several detection modules can be set according to production requirements for batch sorting of thermostats, with a sorting speed of up to more than 20 per minute, and the sorting efficiency is increased by at least about 40%; compared with the thermal oven, the heating uniformity of the thermostat sorting equipment in the embodiment of the present application is ±0.4°C, the heating accuracy is controlled at about 0.1°C, and about 1 / 10 of the energy consumption is saved, greatly reducing the production cost.

[0028] (2) The pusher cross beam arranged by the pusher mechanism extends along the sorting direction. By arranging several pusher carriers in the length direction of the pusher cross beam, it is used to synchronously push several thermostats on the heating module, so as to achieve the purpose of batch pushing of thermostats for each pusher cross beam, and further improve the sorting efficiency of the thermostat; the feeding system is also provided with an X-axis feeding cylinder and a Y-axis feeding cylinder, which are used to drive the pusher carriers on the pusher cross beam to slide along the Y-axis feeding slide rail and the X-axis feeding slide rail in turn, so as to achieve the purpose of automatically pushing the thermostat along the sorting direction;

The whole process is automated, improving the feeding efficiency and quality.

[0030] (3) Before the thermostat of the vibrating bowl enters the heating module through the linear vibrating track, it is first conveyed to the angle adjustment mechanism of the feeding system.

[0044] a. Thermostat. Detailed implementation manner

[0045] Next, in combination with the accompanying drawings and the detailed implementation manner, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0046] As Figures 1-7 shown, a thermostat sorting machine is used for heating and sorting the lower action limit, upper action limit, upper reset limit, and lower reset limit of a snap-action thermostat a, so as to sort out qualified products. The thermostat sorting machine includes a control cabinet 50 for installing a control system. A workbench 40 is provided on the control cabinet 50. An upper feeding station 10, a sorting station 20, and an unloading station 30 are sequentially arranged on the workbench 40 along the sorting direction.

[0047] More specifically, the upper feeding station 10 is provided with a feeding 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 an unloading system 31.

[0048] Among them, the feeding system 11 includes a vibrating disk 110, a linear vibrating track 111, an angle adjusting mechanism 112 and a first clamping mechanism 115. The vibrating disk 110, the linear vibrating track 111, the angle adjusting mechanism 112 and the first clamping mechanism 115 are all arranged on the workbench 40. Several vibrating disks 110 can be set according to the usage requirements. The number of linear vibrating tracks 111 and angle adjusting mechanisms 112 is corresponding to the number of vibrating disks 110. The linear vibrating track 111 is arranged between the vibrating disk 110 and the angle adjusting mechanism 112. Therefore, the thermostat a on the vibrating disk 110 vibrates to the angle adjusting mechanism 112 through the linear vibrating track 111, and the angle of the terminals of the thermostat a is adjusted by the angle adjusting mechanism 112.

[0049] In addition, the angle adjusting mechanism 112 is arranged on the feeding side of the detection system 22. The angle adjusting mechanism 112 has a carrier table and a rotating motor 1121. The carrier table and the linear vibrating track 111 are arranged at the same feeding plane height, and the carrier table is connected to the output end of the rotating motor 1121. When the thermostat a vibrates to the carrier table through the linear vibrating track 111, the carrier table is driven to rotate by the rotating motor 1121, so as to adjust the angle of the terminals of the thermostat a to correspond to the detection position of the detection system 22.

[0050] In order to ensure the smooth progress of the automatic feeding process, a feeding position sensor 117 is arranged at the end of the linear vibrating track 111, which is used to detect when the thermostat a reaches the end of the linear vibrating track 111, and feedback a position signal to the angle adjusting mechanism 112 to prepare for rotation and adjust the placement angle of the terminals of the thermostat a. And a feeding position sensor 117 is arranged at the position of the angle adjusting mechanism 112, which is used to detect the thermostat a after adjusting the terminal angle and feedback a signal to the first clamping mechanism 115 to clamp the thermostat a with adjusted terminal angle onto the heating plate 2201.

[0051] Specifically, the number of the first clamping mechanisms 115 can be increased or decreased according to the actual usage requirements. The first clamping mechanism 115 preferably adopts a manipulator. A vertical feeding support 113 is installed on the feeding side of the detection system 22 and on the workbench 40. A first clamping slide rail 114 extending along the sorting direction is arranged at the upper end of the feeding support 113.

[0052] The first clamping mechanism 115 is movably arranged on the first clamping slide rail 114 through a slide block. A first clamping cylinder 116 and a first lifting slide rail 118 are also arranged on the slide block. The first clamping cylinder 116 at least includes a cylinder for driving the first clamping mechanism 115 to reciprocate along the direction of the first clamping slide rail 114, a cylinder for driving the first clamping mechanism 115 to lift along the direction of the first lifting slide rail 118, and a cylinder for controlling the first clamping mechanism 115 to clamp the thermostat a. Therefore, driven by the first clamping cylinder 116, the first clamping mechanism 115 can clamp the thermostat a adjusted by the angle adjustment mechanism 112 along the direction of the first clamping slide rail 114 and send it to the detection system 22 for heating and sorting.

[0053] In this way, before the thermostat a of the vibrating disk 110 enters the detection system 22 through the linear vibrating track 111, it is first conveyed to the angle adjustment mechanism 112, and the rotating motor 1121 drives the carrier table to rotate, so as to adjust the terminal angle of the thermostat a to correspond to the detection position of the detection system 22. Furthermore, after the thermostat a enters the detection system 22, the detection system 22 can be aligned with the terminals of the thermostat a for detection, thereby improving the detection accuracy of the connection or disconnection of the two terminals of the thermostat a.

[0054] The feeding system 21 has a feeding driver, a pushing mechanism 214, an X-axis feeding slide rail 210 and a Y-axis feeding slide rail 211. Among them, the feeding driver includes an X-axis feeding cylinder 212 and a Y-axis feeding cylinder 213. The pushing mechanism 214 has a pushing cross beam 2140 and a plurality of pushing carriers 2141. The pushing cross beam 2140 extends along the sorting direction and is arranged on one side of the detection system 22. A plurality of pushing carriers 2141 are arranged along the length direction of the pushing cross beam 2140.

[0055] The X-axis feeding slide rail 210 is installed on the workbench 40 and extends along the sorting direction and is located on one side of the detection system 22. The X-axis feeding cylinder 212 is installed on the workbench 40. The Y-axis feeding cylinder 213 and the Y-axis feeding slide rail 211 are both movably installed on the X-axis feeding slide rail 210 through an X-axis slide block. The pushing cross beam 2140 is movably installed on the X-axis feeding slide rail 210 through a Y-axis slide block.

[0056] Therefore, the output rod of the Y-axis feeding cylinder 213 is connected to the Y-axis slide block. By driving the Y-axis slide block with the Y-axis feeding cylinder 213, the pushing cross beam 2140 can be driven to reciprocate along the direction of the Y-axis feeding slide rail 211, and then drive the pushing carriers 2141 to move towards the thermostat a on the detection system 22 and be positioned at the tail side in the advancing direction of the thermostat a.

[0057] The output rod of the X-axis feeding cylinder 212 is connected to the X-axis sliding seat. By driving the X-axis sliding seat with the X-axis feeding cylinder 212, the pushing beam 2140 can be driven to reciprocate along the sorting direction on the X-axis feeding slide rail 210, thereby driving the pushing carrier 2141 to push the tail side of the thermostat a on the detection system 22, so that the batch of thermostats a slide along the sorting direction on the detection system 22.

[0058] Preferably, several pushing plates 2142 are provided on the side of the pushing carrier 2141 facing the thermostat a on the detection system 22. The several pushing plates 2142 extend towards the detection system 22, and a gap capable of accommodating the thermostat a is provided between adjacent two pushing plates 2142. Several arc-shaped openings 2143 matching the arc of the side of the thermostat a in contact are provided on one side of each pushing plate 2142. Therefore, driven by the X-axis feeding cylinder 212 and the Y-axis feeding cylinder 213, the pushing beam 2140 can drive the pushing carrier 2141 to first move in the Y-axis direction and be positioned at the tail side of the thermostat a, and then push the thermostat a in the X-axis direction, so that the thermostat a can gradually slide along the sorting direction on the detection system 22.

[0059] In this way, by arranging several pushing carriers 2141 in the length direction of the pushing beam 2140 to synchronously push several thermostats a on the heating module 220, the purpose of batch pushing the thermostats a by each pushing beam 2140 is realized, and the sorting efficiency of the thermostats a is further improved; the feeding system 21 is also provided with an X-axis feeding cylinder 212 and a Y-axis feeding cylinder 213, which are used to drive the pushing carriers 2141 on the pushing beam 2140 to slide along the Y-axis feeding slide rail 211 and the X-axis feeding slide rail 210 in sequence, so as to realize the purpose of automatically pushing the thermostats a along the sorting direction; in addition, an arc-shaped opening 2143 is provided on the side of the pushing plate 2142 of the pushing carrier 2141 in contact with the side of the thermostat a, and the arc-shaped opening 2143 matches the arc of the side of the thermostat a in contact. When pushing the thermostat a, the pushing plate 2142 can stably push the thermostat a through the arc-shaped opening 2143, preventing the problem that the thermostat a deviates from the pushing plate 2142 or detaches from the heating plate 2201 during the pushing process, with full-automatic operation, improving the feeding efficiency and quality.

[0060] The detection system 22 has several heating modules 220 and detection modules 221. Among them, the heating module 220 has a heating plate 2201 and a heating tube 2202 for providing heat source for the heating plate 2201. Several heating plates 2201 can be arranged in parallel according to sorting requirements, and each heating plate 2201 extends along the sorting direction. Several heating tubes 2202 providing different amounts of heat are arranged along the length direction of the heating plate 2201.

[0061] Specifically, along the sorting direction on the heating plate 2201, there are at least several heating zones including a preheating zone 2203, an action lower limit zone 2204, an action upper limit zone 2205, a reset upper limit zone 2206, and a reset lower limit zone 2207. Therefore, by driving the pusher cross beam 2140 and the pusher carrier 2141 through the X-axis feeding cylinder 212, the thermostat a can be sequentially pushed along the heating plate 2201 to the preheating zone 2203, the action lower limit zone 2204, the action upper limit zone 2205, the reset upper limit zone 2206, and the reset lower limit zone 2207 for heating and sorting at different temperatures. The working temperature range of the heating zones provided in the embodiments of the present application is 45°C - 220°C, and the specific temperature settings of each heating zone can be adjusted according to actual working requirements, which will not be elaborated here.

[0062] In order to enable the thermostat a to be sorted and detected in a timely manner after being heated in each heating zone, the detection module 221 is correspondingly arranged at the discharge end of each heating zone.

[0063] The detection module 221 has a detection cylinder 2210, an elastic pressure rod 2211, and a probe 2212. The detection cylinder 2210, the elastic pressure rod 2211, and the probe 2212 are all installed on the workbench 40 through a detection bracket and are located above the heating module 220. The elastic pressure rod 2211 is arranged between the two probes 2212. Therefore, under the drive of the detection cylinder 2210, first, the elastic pressure rod 2211 vertically descends to tightly press the thermostat a heated in the specified heating zone, and then the two probes 2212 that vertically descend synchronously are abutted against the two terminals of the thermostat a to detect whether the two terminals are connected or disconnected. While feeding a batch of thermostats a on the heating plate 2201, the detection module 221 arranged at the discharge end of each heating zone can work independently and without interference, thereby realizing the batch heating and detection of the thermostat a.

[0064] The blanking system 31 has a second clamping mechanism 314, a reset upper limit hopper 316, a reset lower limit hopper 317, an action lower limit hopper 318, an action upper limit hopper 319, and a qualified product hopper 320. The number of the second clamping mechanisms 314 can be increased or decreased according to actual usage requirements. The second clamping mechanism 314 preferably adopts a manipulator. On the discharge side of the detection system 22 and on the workbench 40, a vertically arranged blanking bracket 310 is installed, and the upper end of the blanking bracket 310 is provided with a second clamping slide rail 312 extending along the sorting direction.

[0065] Moreover, the second clamping slide rail 312 extends along the sorting direction and is located above each hopper. A blanking motor 311 is arranged on the second clamping slide rail 312. The second clamping mechanism 314 is movably arranged on the second clamping slide rail 312 through a sliding seat. A second clamping cylinder 315 and a second lifting slide rail 313 are also arranged on the sliding seat. The blanking motor 311 is connected to the sliding seat for installing the second clamping mechanism 314, the second clamping cylinder 315 and the second lifting slide rail 313, and drives the sliding seat to reciprocate along the direction of the second clamping slide rail 312.

[0066] The second clamping cylinder 315 at least includes a cylinder for driving the second clamping mechanism 314 to lift in the direction of the second lifting slide rail 313 and a cylinder for controlling the second clamping mechanism 314 to clamp the thermostat a. Therefore, driven by the blanking motor 311 and the second clamping cylinder 315, the second clamping mechanism 314 can clamp the thermostat a along the track directions of the second clamping slide rail 312 and the second lifting slide rail 313 to the corresponding hopper. Therefore, the second clamping mechanism 314 clamps the thermostat a after heating detection to the corresponding hopper in the setting direction of the second clamping slide rail 312 and according to the detection feedback signal of the thermostat a by the detection module 221 in each heating area, so as to replace manual blanking, avoid human error operation, reduce labor intensity, and improve blanking efficiency and accuracy.

[0067] Regarding the detection requirements for the thermostat a, the second clamping mechanism 314 is used to clamp the thermostat a with two terminals heated and disconnected in the action lower limit area 2204 to the action lower limit hopper 318, clamp the thermostat a with two terminals heated and connected in the action upper limit area 2205 to the action upper limit hopper 319, clamp the thermostat a with two terminals still heated and disconnected in the reset upper limit area 2206 to the reset upper limit hopper 316, clamp the thermostat a with two terminals still heated and connected in the reset lower limit area 2207 to the reset lower limit hopper 317, and clamp the thermostat a with two terminals heated and restored to be disconnected in the reset lower limit area 2207 to the qualified product hopper 320.

[0068] In addition, detection position sensors are arranged at the discharge ends of the action lower limit area 2204, the action upper limit area 2205, the reset upper limit area 2206 and the reset lower limit area 2207. The position signal of the thermostat a is fed back to the detection module 221 through the detection position sensors. And a detection position sensor is also arranged at the end of the heating plate 2201 to obtain the position of the thermostat a after detection reaching the end of the heating plate 2201 and feed back the position signal of the thermostat a to the second clamping mechanism 314, so that the second clamping mechanism 314 can timely clamp the thermostat a to each hopper.

[0069] The sorting work of the thermostat a by the thermostat sorter in the embodiment of the present application includes the following steps:

[0070] S1. The loading station 10 is provided with a loading system 11. The thermostat a on the vibrating bowl 110 of the loading system vibrates through the linear vibrating track 111 to the angle adjusting mechanism 112. After the angle of the thermostat a is adjusted by the angle adjusting mechanism 112, it is clamped and sent to the sorting station 20 by the first clamping mechanism 115;

[0071] S2. The sorting station 20 is provided with a feeding system 21. The feeding driver drives the pushing carrier 2141 of the pushing mechanism 214 to move along the Y-axis slide rail to the heating module 220, and drives the pushing carrier 2141 to move along the X-axis slide rail and push several thermostats a on the heating module 220 to each heating zone in turn along the sorting direction through the pushing plate 2142 of the pushing carrier 2141;

[0072] S3. The sorting station 20 is provided with a detection system 22. It heats the thermostats a on the action lower limit zone 2204, action upper limit zone 2205, reset upper limit zone 2206 and reset lower limit zone 2207 to different temperatures through the heating module 220, and it also detects whether the two terminals of the heated thermostat a are connected or disconnected through the detection module 221; Specifically:

[0073] If the two terminals of the thermostat a are disconnected when heated in the action lower limit zone 2204, it is clamped and sent to the action lower limit hopper 318 by the second clamping mechanism 314;

[0074] If the two terminals of the thermostat a remain connected when heated in the action upper limit zone 2205, it is clamped and sent to the action upper limit hopper 319 by the second clamping mechanism 314;

[0075] If the two terminals of the thermostat a are still disconnected when heated in the reset upper limit zone 2206, it is clamped and sent to the reset upper limit hopper 316 by the second clamping mechanism 314;

[0076] If the two terminals of the thermostat a remain connected when heated in the reset lower limit zone 2207, it is clamped and sent to the reset lower limit hopper 317 by the second clamping mechanism 314;

[0077] And if the thermostat a is heated and detected as above and is transported to the reset lower limit zone 2207 and the two terminals are restored to be disconnected when heated, it is clamped and sent to the qualified product hopper 320 by the second clamping mechanism 314.

[0078] In this way, for the thermostat sorter provided by the embodiment of the present application, the first clamping mechanism 115 arranged at the feeding station is used for automatically feeding the thermostat a. The heating module 220 with several heating zones is arranged at the sorting station 20 and is used to provide different heating temperatures for the thermostat a reaching different heating zones on the heating module 220. The pusher carrier 2141 of the pusher mechanism 214 is driven by the feeding driver to realize the automatic feeding of the thermostat a. Along with the feeding process of the thermostat a on the heating module 220, the detection module 221 is simultaneously set to detect whether the two terminals of the thermostat a on each heating zone are connected or disconnected. The second clamping mechanism 314 of the discharging system 31 clamps the thermostat a to the corresponding hopper according to the detection signal fed back by the detection module 221.

[0079] Compared with the previous implementation means of using the chain and fixture of the hot oven to convey and heat the thermostat, the sorting work of the thermostat a in the embodiment of the present application is fully automated without manual intervention, eliminating problems such as misfeeds, missing feeds, and incorrect feeding and placement by manual operation, and improving the sorting quality of the thermostat a. Several detection modules 221 can be set according to production requirements for batch sorting of the thermostat a, with a sorting speed of up to more than 20 per minute, and the sorting efficiency is increased by at least about 40%. Compared with the hot oven, the heating uniformity of the thermostat sorting equipment in the embodiment of the present application is ±0.4°C, and the heating accuracy is controlled at about 0.1°C, saving about 1 / 10 of the energy consumption and greatly reducing the production cost.

[0080] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
