Description

Technical Field

[0001] The present invention relates to the technical field of temperature controller thermal adjustment equipment, and more specifically, to an automatic thermal adjustment furnace for temperature controllers. Background Art

[0002] An adjustable temperature controller uses a bimetal strip set at a certain temperature on the temperature controller body as a heat-sensitive reaction component. When the temperature of the main component of the product increases, the heat generated is transferred to the bimetal strip. When the operating temperature is reached, the bimetal strip deforms, causing the contact to disconnect. When the temperature drops to the reset temperature, the bimetal strip quickly returns to its original state, causing the contact to close, thereby achieving the purpose of disconnecting or connecting the circuit and controlling the circuit.

[0003] An adjustable temperature controller is a product that accurately adjusts the temperature according to customer requirements. Before leaving the factory, the temperature (the temperature required for the adjustable temperature controller to disconnect) of the adjustable temperature controller must be adjusted to meet the customer's needs. Currently, the adjustment and calibration method for the adjustable temperature controller is to place the adjustable temperature controller in a furnace with a constant temperature equal to the temperature value for heat sensing. When the temperature of the adjustable temperature controller is the same as the temperature in the furnace, the screws inside the adjustment rotating shaft of the adjustable temperature controller are adjusted manually by employees. Currently, due to the high temperature in the furnace, the manual operation environment has a high temperature, and the manual adjustment has a large labor intensity. There are problems such as high labor costs and low efficiency, and the adjustment and calibration accuracy cannot be guaranteed due to differences in the proficiency of workers.

[0004] Therefore, there is a need for an integrated machine for automatic temperature adjustment, screening, and dispensing of adjustable temperature controllers. Summary of the Invention

[0033] Such as Figure 1As shown in the figure, a thermostat automatic heat adjustment furnace includes a frame 1. An electric control box 30 is provided at one end of the frame 1. It is characterized in that a chain sprocket 2 is provided above one end of the frame 1, and a fixture chain tensioning mechanism 70 is provided at the other end. The chain sprocket 2 and the fixture chain tensioning mechanism 70 are connected by surrounding with a fixture chain. A plurality of thermostat fixtures 53 are installed on the fixture chain. Along the transmission direction of the fixture chain on the frame 1, there are successively arranged a heating box 80, an automatic heat adjustment mechanism 90, an air cooling mechanism 140, a defective product sorting mechanism 150, an adjusting screw dispensing mechanism 200, a bimetal and porcelain rice dispensing mechanism 220, and a qualified product taking-out mechanism 240. The automatic heat adjustment mechanism 90 is arranged above one end of the heating box 80, and the lower end of the heat adjustment mechanism 90 extends into the heating box 80. The air cooling mechanism 140, the defective product sorting mechanism 150, the adjusting screw dispensing mechanism 200, the bimetal and porcelain rice dispensing mechanism 220, and the qualified product taking-out mechanism 240 are all arranged outside the heating box 80.

A heat preservation box is covered on the fixture chain tensioning mechanism 70, and the heat preservation box is communicated with the heating box 80; Along the transmission direction of the fixture chain on the frame 1, there are successively arranged a heating box 80 for preheating and heat adjustment of the thermostat, an automatic heat adjustment mechanism 90 for automatically and accurately adjusting and calibrating the disconnection action temperature of the thermostat, an air cooling mechanism 140 for blowing and cooling the thermostat, a defective product sorting mechanism 150 for sorting the thermostats with defective products during adjustment and calibration, an adjusting screw dispensing mechanism 200 for dispensing glue on the adjusting screws of the thermostat, a bimetal and porcelain rice dispensing mechanism 220 for dispensing glue on the bimetal and spring porcelain rice of the thermostat, and a qualified product taking-out mechanism 240 for taking out the adjusted and calibrated thermostats, so that the whole process reduces manual intervention, and solves the problems of high operating environment temperature, high labor intensity, high labor cost, low efficiency, and inability to guarantee the adjustment and calibration accuracy of products for current employees.

[0034] As Figure 2 shown, the thermostat fixture 53 includes a fixture seat 530. A fixture connecting piece 534 connected to the fixture chain is provided below the fixture seat 530. A product bracket positioning piece 533 is provided above the fixture seat 530. A product rivet positioning pin 532 is provided on one side of the product bracket positioning piece 533, and a guiding positioning hole 531 is provided on the other side; In this embodiment, a total of 140 thermostat fixtures 53 are provided, and the 140 are equally distributed and locked on the fixture chain. The thermostat product is placed in the thermostat fixture 53. The rivet in the thermostat product is inserted into the product rivet positioning pin 532, the bracket in the thermostat product is positioned by the product bracket positioning piece 533, and the guiding positioning hole 531 on the thermostat fixture 53 can be used for positioning in subsequent processes, which is convenient for work.

[0035] AsFigure 3 As shown, the fixture chain tensioning mechanism 70 includes a machine table 50. Above the machine table 50, there is a tensioning adjustment movable plate 71. On both sides of the tensioning adjustment movable plate 71, there are adjustment movable plate guide blocks 72 installed on the machine table 50. Above the tensioning adjustment movable plate 71, two bearing seats 73 are installed. On the two bearing seats 73, a sprocket transmission shaft 74 is installed. At the upper end of the sprocket transmission shaft 74, there is a tensioning sprocket 75 connected to the fixture chain. Above one side of the tensioning adjustment movable plate 71, there are at least three tensioning adjustment pull seats 76. On one side of the tensioning adjustment movable plate 71, there are at least three tensioning adjustment nut blocks 78 installed on the machine table 50. The tensioning adjustment nut block 78 and the tensioning adjustment pull seat 76 are connected by a tensioning adjustment screw rod 77. A tensioning spring 79 is sleeved on the tensioning adjustment screw rod 77. One end of the tensioning spring 79 presses against the end of the tensioning adjustment screw rod 77, and the other end presses against the tensioning adjustment pull seat 76; because the fixture chain is installed on the tensioning sprocket 75, the tensioning sprocket 75 is installed on the sprocket transmission shaft 74, the sprocket transmission shaft 74 is installed in the bearing seat 73, the bearing seat 73 is installed on the tensioning adjustment movable plate 71, the tensioning adjustment nut block 78 is locked on the machine table 50, the tensioning adjustment pull seat 76 holds up the tensioning adjustment screw rod 77, and the tensioning adjustment movable plate 71 is guided by the adjustment movable plate guide block 72. By adjusting the tensioning adjustment screw rod 77, the tensioning adjustment pull seat 76 is pulled. The movement of the tensioning adjustment pull seat 76 drives the tensioning adjustment movable plate 71. The tensioning adjustment pull seat 76 is subjected to the elastic force of the tensioning spring 79. Therefore, adjusting the tensioning adjustment screw rod 77 can adjust the tightness of the fixture drive chain 52. When the fixture chain is in transmission operation, due to the elastic force of the tensioning spring 79, it is in a flexible state. In the case of thermal expansion and contraction, it can also maintain smooth operation; the incubator (not shown) covers the fixture chain tensioning mechanism 70 to prevent heat dissipation. This is because the fixture chain is installed on the equipment in a ring connection manner. When the equipment is running, when the fixture chain passes through the preheating tank 800 and the adjustment tank 801, the fixture chain is prone to getting stuck due to thermal expansion and contraction after being heated. Therefore, the fixture chain tensioning mechanism 70 is provided to ensure that the fixture drive chain 52 is in a flexible state during the operation of the equipment and can operate smoothly while preventing heat dissipation.

[0036] As Figure 4As shown, the heating box 80 includes a preheating tank 800 and an adjustment tank 801 with two independent spaces. The automatic thermal adjustment mechanism 90 is arranged above one end of the adjustment tank 801. Openings for accommodating the fixture chain are provided at both ends of the preheating tank 800 and the adjustment tank 801. Lower air ducts 802 and upper air ducts 803 are provided in both the preheating tank 800 and the adjustment tank 801. A blower motor 81 is installed below one end of the lower air duct 802 through a blower motor mounting plate 82. The upper end of the blower motor 81 extends into the lower air duct 802 and is equipped with two air wheels 83. A heater 84 is provided in the lower air duct 802. An arc-shaped plate 805 is provided at the other end of the lower air duct 802. A circulation air outlet 804 is provided above the arc-shaped plate 805. An air extraction port 807 communicating with the upper air duct 803 is provided above the air wheel 83. An arc-shaped corner 806 is provided at the upper corner position of the upper air duct 803 close to the air extraction port 807;

[0037] The working process of the heating box 80 is as follows: The heaters 84 in the preheating tank 800 and the adjustment tank 801 generate heat and emit heat. The blower motor 81 rotates to drive the two air wheels 83 to rotate. The rotation of the air wheels 83 blows air, causing the air in the preheating tank 800 and the adjustment tank 801 to circulate respectively. After continuously circulating and heating the air in the preheating tank 800 and the adjustment tank 801, the air temperatures in the preheating tank 800 and the adjustment tank 801 reach uniformity and are kept at a constant temperature stably. The fixture chain drives the thermostat fixture 53, and the thermostat fixture 53 drives the thermostat product to first enter the preheating tank 800 and the fixture chain tensioning mechanism 70, and then enter the adjustment tank 801. The air in the adjustment tank 801 continues to heat the thermostat product at a constant temperature. After being heated at a constant temperature in the preheating tank 800 and the adjustment tank 801, the bimetal sheet in the thermostat product has reached a stable state at this time, and the next step of adjusting the disconnection action temperature of the thermostat product can be carried out. Since the bimetal sheet in the thermostat product needs a long time of constant temperature heating from normal temperature to the set action temperature to reach a stable state, the preheating tank 800 and the adjustment tank 801 are used in combination to allow the bimetal sheet in the thermostat product to have sufficient constant temperature heating time. After it reaches a stable state, the next step of adjusting the action temperature of the thermostat product can be carried out.

During the whole process, it can realize fast, accurate, and automatic adjustment and calibration of the product, stabilize the product quality, solve the problem that the adjustment and calibration accuracy of the current product cannot be guaranteed, and can also reduce the labor cost, improve the efficiency, and improve the working environment of the employees.

[0049] The adjustment process of the automatic heat adjustment mechanism 90 is as follows:

[0050] Transport the thermostat product under the adjustment component positioning seat 114, then adjust the extension action of the downward pressure cylinder 104 to push the adjustment cylinder connecting plate 105. The adjustment cylinder connecting plate 105 pushes the adjustment component support plate 108, the adjustment component support plate 108 pushes the stepping motor mounting plate 109, the stepping motor mounting plate 109 pushes the needle adjustment component guide sleeve shaft 111, and the movement of the needle adjustment component guide sleeve shaft 111 drives the adjustment component positioning seat 114. The adjustment component positioning seat 114 pushes the adjustment shaft distance adjuster 115, and the movement of the adjustment shaft distance adjuster 115 drives the positioning guide post 116. The positioning guide post 116 is inserted into the guiding positioning hole in the positioning fixture. Because the linear guide 99 is installed under the mechanism slide plate 100, when the positioning guide post 116 is inserted into the guiding positioning hole in the positioning fixture, it will automatically slide left and right for adjustment to cooperate with the accurate insertion of the positioning guide post 116 into the guiding positioning hole in the positioning fixture; at the same time of inserting into the guiding positioning hole, the product fixing pressure bar 117 presses down the rivet in the thermostat product. At this time, the rivet in the thermostat product is pressed tightly by the elastic force of the product fixing pressure bar spring 118. At the same time of inserting into the guiding positioning hole, the probe 121 of the adjustment probe mounting block 120 presses down to contact the upper connection piece and the lower connection piece in the thermostat product respectively to obtain the signal that the thermostat product is currently on or off; and at the same time of inserting into the guiding positioning hole, the adjustment needle 113 is inserted into the adjustment shaft of the thermostat product and aligned with the adjustment screw in the adjustment shaft; then the limit piece positioning cylinder 125 extends to push the positioning cylinder connecting block 126, the positioning cylinder connecting block 126 pushes the limit piece positioning sliding plate 127, the limit piece positioning sliding plate 127 pushes the limit piece positioning lifting shaft 129, and the limit piece positioning lifting shaft 129 pushes the limit piece positioning extending block 130 to press down, so that the limit piece positioning extending block 130 leaves the limit piece positioning lifting fastener 133. The limit piece positioning lifting block 132 and the limit piece positioning piece 134 drop due to gravity, and the limit piece positioning piece 134 drops to position the limit piece in the thermostat product. If the limit piece of the thermostat is not positioned, it will rotate along with the adjustment screw during adjustment. Therefore, the limit piece in the thermostat product is positioned by the limit piece positioning piece 134, so as to fix the adjustment shaft of the thermostat product;Then, the stepper motor 110 rotates to drive the needle adjusting connecting piece 112. The rotation of the needle adjusting connecting piece 112 drives the needle adjuster 113. The rotation of the needle adjuster 113 adjusts the adjusting screw within the adjusting shaft of the thermostat product, quickly adjusting the thermostat product to the on state. Then, the limit piece positioning cylinder 125 retracts, pulling the positioning cylinder connecting block 126. The positioning cylinder connecting block 126 pulls the limit piece positioning sliding plate 127. The limit piece positioning sliding plate 127 pulls the limit piece positioning lifting shaft 129. The limit piece positioning lifting shaft 129 pulls the limit piece positioning protruding block 130. The limit piece positioning protruding block 130 lifts the limit piece positioning lifting fastener 133. When the limit piece positioning lifting fastener 133 is lifted, the limit piece positioning lifting block 132 and the limit piece positioning piece 134 are both lifted. The limit piece positioning piece 134 leaves the limit piece in the thermostat product. Thus, the adjusting shaft of the thermostat product is in a state without external force. Then, the needle adjuster 113 rotates to adjust the adjusting screw within the adjusting shaft of the thermostat product, slowly adjusting the thermostat product to the off state. At this time, the off-action temperature of the product has been adjusted. The adjustment pressing cylinder 104 retracts, pulling the adjustment cylinder connecting plate 105. The adjustment cylinder connecting plate 105 pulls the adjustment component support plate 108. The adjustment component support plate 108 pulls the stepper motor mounting plate 109. The stepper motor mounting 109 pulls the needle adjusting component guide sleeve shaft 111. The needle adjusting component guide sleeve shaft 111 pulls the adjustment component positioning seat 114. The adjustment component positioning seat 114 pulls the adjusting shaft distance adjuster 115. The adjusting shaft distance adjuster 115 pulls the positioning guide post 116. The positioning guide post 116 leaves the guiding positioning hole in the positioning fixture. The product fixing pressure bar 117 leaves the rivet in the thermostat product. The test probe 121 leaves the upper connection terminal and the lower connection terminal in the thermostat product. The needle adjuster 113 leaves the adjusting screw of the thermostat product and the adjusting rotating shaft. At this time, all actions are completed, preparing for adjusting the next thermostat product.;

At the upper end of the positioning magnet fixing seat 163, there is a lower strong magnet 164.

[0053] The working process of the defective product sorting mechanism 150 is as follows: Since some thermostat products cannot be adjusted normally in the above-mentioned adjustment groove 801 due to reasons such as the adjustment screw in the adjustment shaft of the thermostat product being too tight to be moved or the adjustment screw being missing, the PLC programmable controller in the equipment automatically records the current defective products. When the defective products are transmitted to the defective product sorting mechanism 150 through the fixture chain, the positioning cylinder 158 of the sorting mechanism extends, pushing the positioning movable block 160 of the sorting mechanism. The positioning movable block 160 of the sorting mechanism pushes the positioning protruding block 162 of the sorting mechanism.

Then, the lifting cylinder 181 of the material taking manipulator extends, pushing the clamping cylinder plate 182 of the material taking manipulator. The clamping cylinder plate 182 of the material taking manipulator pushes the clamping cylinder 183 of the material taking manipulator. The clamping cylinder 183 of the material taking manipulator pushes the clamping jaws 184 of the material taking manipulator. The clamping jaws 184 of the material taking manipulator are aligned with the thermostat product of the defective product. Then, the clamping jaws 184 of the material taking manipulator perform a clamping action to clamp the defective product. The lifting cylinder 181 of the material taking manipulator retracts, moving the defective product to the defective product placement area. Due to the magnetic force of the lower strong magnet 164 and the upper strong magnet 166, the mechanism is automatically corrected and adjusted to the original position. At this time, the defective product sorting mechanism 150 has returned to the original position, preparing for sorting the next defective product.
