Description

Technical Field

[0001] This invention relates to the field of electrical component testing technology, and in particular to an intelligent testing device and method for thermal protectors. Background Technology

[0002] Thermal protectors are widely used in various power distribution facilities and electrical equipment. When the ambient temperature rises to the preset operating temperature, the bimetallic element inside the thermal protector is heated, generates internal stress, and activates, causing the contacts inside the thermal protector to open and thus disconnect the circuit, achieving the thermal protection function for the circuit and electrical appliances. It can be seen that the difference between the actual operating temperature and the expected operating temperature of the thermal protector is crucial to its normal operation. During the manufacturing process, thermal protectors need to undergo actual testing to ensure that the difference between the actual and expected operating temperatures is within a certain range, thereby guaranteeing the normal operation of the thermal protector.

[0003] In existing testing methods, due to the lack of intelligent continuous testing, only a few thermal protectors can usually be taken from each batch as samples to estimate the pass rate of the entire batch. This can easily lead to missed detections and low testing quality. Furthermore, during testing, the wires extending from the thermal protectors are often bent or curled due to compression or other conditions, requiring manual clamping, which reduces testing efficiency. Summary of the Invention

[0005] The present invention provides an intelligent detection device for thermal protectors, comprising multiple detection components, a conveyor chain, and a heater; each detection component is used to detect one thermal protector; the conveyor chain drives the multiple detection components to move cyclically, and the heater is disposed above the detection components;

[0006] Each detection component includes:

[0007] The base is fixed to the conveyor chain and has a placement slot on top;

[0008] Slide the slider down onto the base;

[0009] The abutment block is fixed to the lower slider;

[0010] Slide the slider up onto the base;

[0011] The dividing block is fixed on the upper slider;

[0012] Two clamping blocks are respectively set on both sides of the dividing block, and each clamping block slides on the upper slider in a direction perpendicular to the sliding direction of the upper slider.

[0013] A detector is located at one end of the sliding path of the upper slider; the detector includes two first contacts for detecting whether there is a connection between the two first contacts;

[0014] When the detection component is in the loading and unloading state, the abutment block is away from the placement slot, the upper slider is away from the detector, and the two clamping blocks are away from the dividing block.

[0015] When the detection component is in the detection state, the abutment block is close to the placement slot, the upper slider is close to the detector, and the two clamping blocks are close to the dividing block; the thermal protector is electrically connected to the two first contacts of the detector; the heater heats the thermal protector.

[0016] Furthermore, the top of the abutment block is provided with an extension section that extends upward toward the placement slot.

[0017] Furthermore, each detection component also includes:

[0018] The push block slides on the lower slider, and the sliding direction is parallel to the sliding direction of the lower slider;

[0019] The first spring is disposed between the push block and the lower slider, and is located on the side of the push block away from the abutment block.

[0020] Furthermore, it also includes two push rails located at the bottom of the detection component;

[0021] In each detection component:

[0022] The push block is equipped with a first push post that extends downward, and the upper slider is equipped with a second push post that extends downward; the first push post and the second push post extend into two push tracks respectively.

[0023] Furthermore, in each detection component:

[0024] Two guide ramps are provided on the base, located on both sides of the two clamping blocks, and the distance between the two guide ramps gradually decreases along the direction towards the detector; the side of each clamping block is in contact with one guide ramp;

[0025] The second spring is positioned between the two clamping blocks.

[0026] Furthermore, a second contact is provided on both sides of the dividing block; two third contacts are provided on the side of the upper slider facing the detector; the two second contacts are electrically connected to the two third contacts respectively; when the upper slider moves to the position closest to the detector, the two third contacts abut against the two first contacts respectively.

[0027] Furthermore, two electrically connected fourth contacts are provided on the side of the lower slider away from the detector; two fifth contacts are provided on the base; when the lower slider moves to the position furthest from the detector, the two fourth contacts abut against the two fifth contacts respectively.

[0028] Furthermore, the detector includes a first branch and a second branch connected in parallel with the battery;

[0029] The first branch includes a first light-emitting diode, a first contact, a second contact, and a third contact;

[0031] This invention also provides a method for intelligent detection of thermal protectors, using the intelligent detection device for thermal protectors as described above, comprising the following steps:

[0032] The conveyor chain is divided into a loading area, a detection area, a buffer area, and an unloading area. In the loading, detection, and buffer areas, the detection components face upwards, while in the unloading area, the detection components face downwards.

[0033] The detection area is continuously heated;

[0034] For each detection component:

[0035] When the detection component reaches the loading area, the detection component switches to the loading and unloading state, and a thermal protector is placed on the detection component.

[0036] When the detection component arrives at the detection area, it switches to detection mode and uses the detector to check whether the thermal protector disconnects at the set temperature; if it does not disconnect, the thermal protector is deemed unqualified; if it disconnects, the thermal protector is deemed qualified.

[0037] When a detection component carrying a defective thermal protector arrives at the buffer area, the conveying stops and an alarm is issued; when a detection component carrying a qualified thermal protector arrives at the buffer area, the conveying does not stop, and the detection component is directly conveyed to the material feeding area.

[0038] When the detection component reaches the unloading area, the detection component switches to the unloading state.

[0039] Furthermore, the testing area is divided into a low-temperature zone and a high-temperature zone. The temperature in the low-temperature zone is lower than the set temperature, and the temperature in the high-temperature zone is equal to the set temperature. If the thermal protector does not disconnect in the low-temperature zone but disconnects in the high-temperature zone, the thermal protector is considered qualified; otherwise, it is considered unqualified.

[0040] The technical solution of this invention can achieve the following technical effects:

[0041] This invention, through specially designed detection components, can automatically clamp thermal protectors, organize and clamp thermal protector wires, and detect the operating temperature of thermal protectors, greatly improving the detection efficiency of thermal protectors. Furthermore, with the cooperation of the transmission chain, this device can also achieve continuous and rapid detection of all thermal protectors, effectively preventing defective products from being released due to missed detections.

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0061] The “electrical connection” described in this article mainly refers to the ability of two components to conduct electricity to each other. The two components can be connected in various ways, such as by wires or copper sheets, to achieve the “electrical connection” effect.

[0062] This invention relates to an intelligent detection device for thermal protectors, such as... Figure 1As shown, this device mainly includes multiple detection components, a conveyor chain, and a heater. Each detection component is used to detect the on / off state of a thermal protector. Multiple detection components are distributed along the conveyor chain, each fixed to a chain block, allowing the conveyor chain to drive the multiple detection components in a cyclical movement. Conveyor chains are located on both sides of each detection component, and the movement of the two conveyor chains is synchronized to ensure the smoothness of the detection component's movement. The heater is positioned above the detection component, close to but not in contact with the thermal protector.

[0063] The specific structure of each detection component is as follows: Figures 2-7 As shown, it includes:

[0064] The base 1 is fixed on the conveyor chain and is used to support other components of the detection assembly; a chain block is welded to both ends of the base 1; a placement groove 1a for placing the thermal protector is provided on the top of the base 1; one end of the base 1 with the placement groove 1a has a downward-opening cavity and the other end has an upward-opening cavity, which are used to install the lower slider 2 and the upper slider 4, respectively.

[0065] The lower slider 2 slides horizontally within the downward-facing cavity of the base 1;

[0066] The abutment block 3 is fixed on the lower slider 2 and slides synchronously with the lower slider 2; the abutment block 3 extends to the top of the base 1, and as the lower slider 2 slides, the abutment block 3 will slide closer to and further away from the placement groove 1a;

[0067] The upper slider 4 slides within the upward-facing cavity of the base 1;

[0068] The dividing block 5 is fixed on the upper slider 4 and slides synchronously with the upper slider 4; the dividing block 5 extends to the top of the base 1, so that the abutting block 3 is located between the dividing block 5 and the placement groove 1a. As the upper slider 4 slides, the dividing block 5 will slide away from and towards the abutting block 3.

[0069] Two clamping blocks 6 are respectively set on both sides of the dividing block 5, and each clamping block 6 slides on the upper slider 4, with the sliding direction perpendicular to the sliding direction of the upper slider 4;

[0070] The detector 7 is located at one end of the sliding path of the upper slider 4; the detector 7 includes two first contacts 7a, and the main body of the detector 7 is used to detect whether there is a connection between the two first contacts 7a.

[0071] Each detection component has two main working states: loading / unloading and detection. As the conveyor chain carries the detection component to different positions, the component switches between these two states. The position of the component in each state is as follows:

[0072] When the detection component is in the loading / unloading state, such as Figure 8As shown, the lower slider 2 moves the abutment block 3 to the position furthest from the placement slot 1a. At this point, the distance between the placement slot 1a and the abutment block 3 is large enough for personnel to easily place the thermal protector into the placement slot 1a. The upper slider 4 moves to the position furthest from the detector 7, causing the dividing block 5 and the abutment block 3 to fit together, and the two clamping blocks 6 to move away from the dividing block 5, leaving space for the thermal protector wires. Because the base of the thermal protector wires is sealed with resin, the wire base can maintain a relatively straight state. At this time, the abutment block 3 and the dividing block 5 of the detection component are located between the bases of the two wires. Therefore, even if the free end of the thermal protector wires is bent significantly, it will not affect the placement of the thermal protector.

[0073] When the detection component is in detection mode, such as Figure 9 As shown, the lower slider 2 moves the abutment block 3 closer to the placement slot 1a, and the abutment block 3 abuts against the thermal protector, thereby fixing the thermal protector. The upper slider 4 moves towards the detector 7, and the dividing block 5 also moves from the root of the wire to the free end of the wire. During the movement, if the free ends of the two wires of the thermal protector cross, the dividing block 5 can separate the two wires. During the movement of the upper slider 4, the two clamping blocks 6 also move towards the dividing block 5. If the two wires of the thermal protector bend outward, the two clamping blocks 6 will gradually bring the two wires together, eventually clamping the free ends of the two wires, so that the exposed copper wires at the free ends of the two wires of the thermal protector can be electrically connected to the two first contacts 7a of the detector 7. The detector 7 can detect the continuity of the thermal protector by detecting the continuity between the two first contacts 7a. When the detection component reaches the detection area, the heater heats the thermal protector, and the detector 7 determines whether the thermal protector will disconnect at the set temperature.

[0074] Based on the above-mentioned intelligent detection device for thermal protectors, the present invention also provides an intelligent detection method for thermal protectors, the steps of which include:

[0075] First, the conveyor chain is divided into a feeding area, a detection area, a buffer area, and a discharging area. In the feeding, detection, and buffer areas, the detection components face upwards, while in the discharging area, the detection components face downwards. Heaters are all located in the detection area.

[0076] When starting the test, first set the temperature of each heater to continuously heat the test area; then the conveyor chain can be turned on to drive the test components to start moving.

[0077] For each detection component:

[0078] When the detection component arrives at the loading area, the detection component switches to the loading and unloading state, and personnel or robotic arms place thermal protectors on the detection component in the loading area;

[0079] When the detection component reaches the detection area, it switches to the detection state. At this time, the heater heats the thermal protector, and the detector 7 checks whether the thermal protector disconnects at the set temperature. If it does not disconnect, the thermal protector is deemed unqualified; if it disconnects, the thermal protector is deemed qualified.

[0080] When a detection assembly carrying a defective thermal protector arrives at the buffer area, the conveyor belt stops and an alarm is triggered. Personnel or a robotic arm removes the defective thermal protector from the area before the conveyor belt restarts. When a detection assembly carrying a qualified thermal protector arrives at the buffer area, the conveyor belt does not stop and is directly conveyed to the material feeding area.

[0081] When the detection component reaches the unloading area, it switches to the unloading state. If there is a qualified thermal protector on the detection component at this time, the thermal protector will fall down automatically because the detection component is facing down in the unloading area. Only a collection box needs to be set up below to achieve automatic collection of qualified thermal protectors.

[0082] Preferably, the detection area can be divided into a low-temperature zone and a high-temperature zone. The temperature in the low-temperature zone is lower than the set temperature, and the temperature in the high-temperature zone is equal to the set temperature. If the thermal protector does not disconnect in the low-temperature zone but disconnects in the high-temperature zone, the thermal protector is considered qualified; otherwise, it is considered unqualified. This allows for a more accurate determination of whether the thermal protector's disconnection temperature is the set temperature, avoiding the under-detection of overly sensitive thermal protectors (i.e., unqualified thermal protectors that disconnect at relatively low temperatures).

[0083] Preferably, an extension section 3a is provided on the top of the abutment block 3, extending upward toward the placement groove 1a. After the abutment block 3 moves toward the placement groove 1a, the extension section 3a will reach above the thermal protector, thereby restricting the vertical movement of the thermal protector and improving the fixing effect on the thermal protector. After the abutment block 3 moves away from the placement groove 1a, the extension section 3a will also move completely out of the top range of the placement groove 1a, avoiding any impact on the placement of the thermal protector. Preferably, a slope is provided on the top of the extension section 3a to guide the insertion of the thermal protector.

[0084] To avoid excessive pressure on the thermal protector from contact block 3, it is preferable to... Figure 7 As shown, each detection component also includes the following settings:

[0085] Push block 8 slides on lower slider 2, and the sliding direction is parallel to the sliding direction of lower slider 2; in push block 8 and lower slider 2, push block 8 acts as the driving member to drive the movement of lower slider 2;

[0086] The first spring 9 is disposed between the push block 8 and the lower slider 2, and is located on the side of the push block 8 away from the abutment block 3.

[0087] The principle behind this structure is as follows:

[0088] During loading and unloading, such as Figure 10 As shown, the push block 8 will move to the right, and the right side of the push block 8 will abut against the lower slider 2, thereby directly driving the entire lower slider 2 to move to the right, so that the abutting block 3 is away from the placement groove 1a.

[0089] During the detection state, push block 8 to the left, as follows: Figure 11 As shown, the abutting block 3 will abut against the thermal protector. The moving distance of the pushing block 8 is greater than the distance between the abutting block 3 and the thermal protector. The lower slider 2 will be unable to move due to the abutting block 3. Then, the part of the pushing block 8 that moves more will compress the first spring 9. At this time, the thrust generated by the abutting block 3 on the thermal protector is the reaction force of the first spring 9. Regardless of whether there is an error between the lengths of the thermal protectors, the compression of the first spring 9 is basically the same. Therefore, the reaction force generated on the thermal protector is also basically the same, thus ensuring that the thermal protector that is too long will not be subjected to excessive pressure, and the thermal protector that is too short will not loosen due to insufficient pressure from the abutting block 3.

[0090] If no thermal protector is installed, then when pushing block 8 to the left, as... Figure 12 As shown, since there is no thermal protector to restrict the contact block 3, the sliding block 2 and the contact block 3 will move to the leftmost end along with the push block 8.

[0091] To reduce the number of power-providing devices in the detection assembly and make it more adaptable to this cyclical motion scenario, this device uses two push rails 10 to drive the movement of the push block 8 and the upper slider 4, as follows: Figure 1 and Figures 10-12 As shown, the push rail 10 is set at the bottom of the detection component; the two push rails 10 correspond to the length of the conveyor chain, and the distance between the two push rails 10 is set according to the state requirements of the detection component in the loading area, detection area, buffer area and unloading area;

[0092] In each detection component:

[0093] The push block 8 is provided with a downwardly extending first push post 8a, and the upper slider 4 is provided with a downwardly extending second push post 4a; the first push post 8a and the second push post 4a extend into the two push tracks 10 respectively.

[0094] Similarly, to reduce the amount of power supply equipment, the movement of the two clamping blocks 6 is structurally designed as follows, in each detection component:

[0095] Two guide ramps 1b are provided on the base 1. The two guide ramps 1b are located on both sides of the two clamping blocks 6, and the distance between the two guide ramps 1b gradually decreases along the direction toward the detector 7; the side of each clamping block 6 is in contact with a guide ramp 1b.

[0096] The second spring 11 is disposed between the two clamping blocks 6. The second spring 11 will ensure that the side of each clamping block 6 is always in contact with a guide slope 1b.

[0097] When the upper slider 4 moves toward the detector 7, the distance between the two guide ramps 1b gradually decreases, which will automatically push the two clamping blocks 6 closer together to clamp the wire; when the upper slider 4 moves away from the detector 7, the distance between the two guide ramps 1b gradually increases, and under the push of the second spring 11, the two clamping blocks 6 will separate from each other.

[0098] To ensure a smooth electrical connection between the thermal protector wire and the detector 7, this device does not directly attach the thermal protector wire to the two first contacts 7a of the detector 7. Instead, it sets second contacts 5a on both sides of the dividing block 5, and sets two third contacts 4b on the side of the upper slider 4 facing the detector 7. The two second contacts 5a are electrically connected to the two third contacts 4b respectively. When the upper slider 4 moves to the position closest to the detector 7, the two clamping blocks 6 clamp the protector wire with the second contacts 5a on the dividing block 5, preventing the wire from loosening. The larger contact area makes it easier for them to adhere to each other. At this time, the two third contacts 4b abut against the two first contacts 7a respectively. The structure of each contact is a copper plate with elastic sheet, resulting in a larger contact area and a tighter contact.

[0099] Furthermore, based on the above structure, this device can also detect whether there is a thermal protector on each detection component, thereby avoiding false judgments caused by the detector 7 continuously disconnecting due to the absence of a thermal protector. Specifically, as follows:

[0100] Two electrically connected fourth contacts 2a are provided on the side of the lower slider 2 away from the detector 7; two fifth contacts 1c are provided on the base 1; when the lower slider 2 moves to the position furthest away from the detector 7, the two fourth contacts 2a abut against the two fifth contacts 1c respectively.

[0101] like Figures 10-11 As shown, when the detection component has a thermal protector, regardless of the operating state of the detection component, the slider 2 cannot move to the far left, meaning that the fourth contact 2a and the fifth contact 1c cannot make contact with each other. However, if the detection component does not have a thermal protector, when the detection component switches to detection, the slider 2 can move to the far left, at which point the fourth contact 2a and the fifth contact 1c will abut, and the four contacts will be connected. Therefore, by using detector 7 or a similar detection device to detect the connection between the two fifth contacts 1c, the presence or absence of a thermal protector on the detection component can be determined, avoiding misjudgments that could cause the conveyor chain to stop continuously, thus affecting detection efficiency.

[0102] Since the detection component is in continuous cyclical motion, it is impossible to connect an external wire to the detector 7 to read its detection results. Therefore, this device proposes a special detector 7 that converts the detection results into optical signals, thereby enabling the detection structure to be received by the outside world, such as... Figures 13-15 As shown, its specific structure is as follows:

[0103] Detector 7 includes a first branch 7d and a second branch 7e connected in parallel with battery 7c;

[0104] The first branch 7d includes a first light-emitting diode 7b, a first contact 7a, a second contact 5a, and a third contact 4b; in the detection state, such as Figure 14 As shown, the first contact 7a, the second contact 5a and the third contact 4b are electrically connected to each other, and the clamping block 6 will push the thermal protector wire to the second contact 5a, thereby connecting the first branch 7d. If the thermal protector is closed, the first light-emitting diode 7b will light up.

[0105] The second branch 7e includes a second light-emitting diode 7f, a fourth contact 2a, and a fifth contact 1c. If there is no thermal protector on the detection component, then the fourth contact 2a and the fifth contact 1c will come into contact, and the second branch 7e will be connected, causing the second light-emitting diode 7f to light up.

[0106] At this point, the qualification of the thermal protector can be comprehensively judged by observing the illumination status of the first LED 7b and the second LED 7f. For example, if the second LED 7f is lit (i.e., there is no thermal protector on the detection component), then the status of the first LED 7b can be ignored. Furthermore, because the thermal protector itself is small and thin, traditional methods of directly detecting the presence or absence of the thermal protector are prone to interfering with its fixation or resulting in poor detection effectiveness. This solution, through this indirect detection method, effectively avoids the shortcomings of traditional detection methods.
