Description

Technical Field

[0001] The present invention relates to the technical field of temperature controller production, and in particular to a pressing device and a pressure plate detection production line. Background Art

[0002] The working principle of the liquid expansion temperature controller: Applying the principle of thermal expansion and contraction, liquid working fluid is filled into the power component formed by welding the diaphragm box, capillary, temperature sensing tube or temperature sensing package to form a closed space. By utilizing the physical properties of liquid thermal expansion and contraction, when the temperature sensing tube or temperature sensing package senses the change in external temperature, the volume change of the internal working fluid transforms the change in pressure or volume in the closed space, causing the diaphragm of the diaphragm box to displace. When the set value is reached, the mechanism composed of the diaphragm handle, diaphragm box plate and push rod pushes the fast instantaneous switch composed of elastic elements to produce an on-off action. When the temperature rises, the switch is disconnected, and when the temperature drops, the switch returns to close, realizing the temperature control function.

[0048] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0049] On the one hand, if Figure 1 and Figure 2 As shown, a pressing device in one embodiment of the present invention includes:

[0050] Mounting seat 1;

[0051] The lower pressing component 2 comprises a lower pressing seat 21 arranged on the mounting seat 1, a lower positioning seat 22 arranged on the lower pressing seat 21, and a lower driving member 23 driving the lower pressing seat 21 to move upward;

[0053] The bending component 4 includes a bending driving member 41 and a bending transmission assembly 42 arranged on the mounting seat 1. The bending driving member 41 drives the upper positioning seat 32 to rotate through the bending transmission assembly 42.

[0054] Since the connection between the capillary and the diaphragm box in the power component assembly may break due to up and down movement, a buffer part is provided before the capillary is connected to the diaphragm box, which moves up and down on the pressure plate to buffer the tension, thereby ensuring the service life of the power component assembly; at the same time, the positioning ring, diaphragm box and pressure plate are stacked and pressed in sequence, and the positioning ring is pressed on the connecting end of the diaphragm box to firmly fix the diaphragm box on the pressure plate.

[0055] The above-mentioned pressing equipment, through the capillary passing through the bending line notch of the upper positioning seat 32, the bending drive member 41 drives the upper positioning seat 32 to rotate through the bending transmission assembly 42, the capillary is bent into a certain arc segment as the bending line notch rotates, as the lower drive member 23 drives the lower pressure seat 21 to move upward, and the upper drive member 33 drives the upper pressure seat 31 to move downward, the positioning ring buckle is pressed on the connecting end of the membrane box, thereby firmly fixing the membrane box on the pressure plate, and a buffer part is provided before the capillary is connected to the membrane box, which plays a buffering role when moving up and down on the pressure plate, thereby ensuring the service life of the power component.

In this way, the bending rack 421 is driven by the bending cylinder to perform translational motion, thereby driving the bending gear 422 to rotate; the bending rack 421 and the bending gear 422 have compact transmission meshing and high transmission efficiency, which can ensure safety and reliability for long-term use.

[0057] In one embodiment, the bending drive member 41 drives the upper positioning seat 32 to rotate at an angle greater than 70°. In this way, by limiting the rotation angle of the upper positioning seat 32, it is ensured that the arc segment formed by the capillary tube as it rotates along the bending line notch has sufficient length, thereby ensuring that the buffering performance of the arc segment meets the use requirements.

[0058] In one embodiment, the lower pressing component 2 is provided with a first guide unit 24, which includes a first guide column provided on the mounting seat 1 and a first copper sleeve provided on the lower pressing seat 21; the upper pressing component 3 is provided with a second guide unit 34, which includes a first guide hole provided on the mounting seat 1 and a second guide column provided on the upper pressing seat 31. In this way, the first guide unit 24 and the second guide unit 34 respectively ensure the movement direction of the lower pressing seat 21 and the upper pressing seat 31 when they approach the pressing space during the pressing process, thereby ensuring the pressing accuracy.

[0059] In one embodiment, the mounting seat 1 is in a C-shape as a whole, the lower driving member 23 and the upper driving member 33 are both driving cylinders, and the upper positioning seat 32 is provided with a raised positioning block adapted to the positioning ring buckle. In this way, the positioning ring buckle is pressed against the connecting end of the membrane box by the raised positioning block, so that the membrane box is firmly fixed on the pressure plate.

[0060] On the other hand, Figure 1 and Figure 3 , Figure 7As shown, a pressure plate detection production line in one embodiment of the present invention includes a pressure plate detection device 5, a feeding device 6, and a pressing device; the pressure plate detection device 5 is used to detect the pressure plate and screen the pressure plate, and convey the pressure plate that has passed the inspection to the feeding device 6; the feeding device 6 is used to feed the positioning ring buckle, the pressure plate, and the membrane box onto the capillary respectively; the pressing device is used to press the positioning ring buckle, the pressure plate, and the membrane box on the capillary together. Since the pressure plate is bent, the size of the bending angle will affect the disconnection action of the pressure plate, so the pressure plate will be inspected before it is used. In this way, the pressure plate is detected and screened by the pressure plate detection device 5, and the pressure plate that has passed the inspection is conveyed to the feeding device 6, ensuring that the power component assembly formed by pressing the positioning ring buckle, the pressure plate, and the membrane box on the capillary by the pressing device meets the use requirements.

In this way, since the clamping point of the clamping assembly 531 clamping the positioning plate surface of the pressure plate is fixed, the clamping point is used as the reference point O; since the movement performed by the detection contact 533 is a horizontal movement, the vertical height H between the measurement center point of the detection contact 533 and the clamping point can be measured in the preset stage; when the detection drive member 534 drives the detection contact 533 to perform a top contact detection on the inclined plate surface, since the first horizontal distance L1 between the original position point of the detection contact 533 and the clamping point can be measured in the preset stage, the displacement of the detection contact 533 is calculated to obtain the vertical height H of the inclined plate surface. The second horizontal distance L2 between the inclined plate surface and the original position point of the detection contact 533 can be obtained, and the third horizontal distance L3=L1-L2 between the inclined plate surface and the reference point O at the vertical height H can be obtained. The plate length from the reference point O to the detection contact can be calculated by the third horizontal distance L3, the vertical height H, and the Pythagorean theorem; the control component 56 calculates the actual bending slope of the pressure plate, and by comparing with the preset bending slope and judging whether it meets the assembly and use requirements, sends a control signal to the screening component 55, and the screening component 55 screens out the pressure plates with unqualified detection results.

In this way, by setting up two groups of feeding components to perform feeding actions, the subsequent detection component 53 can perform detection actions on the two pressure plates accordingly, thereby improving the detection efficiency; at the same time, two groups of material transfer components are set on the same material transfer seat 521, which has a compact structure and is convenient for reducing production costs.

[0065] In one embodiment, a defective product collection bucket is provided below the first material distribution outlet of the distribution guide cylinder 551, and a transfer component is provided below the second material distribution outlet. The transfer component includes a lifting conveyor belt and a second vibration disk. After the qualified pressure plate falls from the second material distribution outlet to the lifting conveyor belt, the pressure plate is transferred to the second vibration disk of the second loading component 622 along with the rubber of the lifting conveyor belt, and the second loading component 622 passes the pressure plate into the capillary.
