Technical Field

[0001] This utility model relates to a sorting machine and belongs to the field of thermal protector testing technology. Background Technology

[0002] Currently, thermal protectors, as a key component of electrical safety, are widely used in household appliances, industrial equipment, and electronic products. Their quality and performance directly affect the safe operation of these devices. With the increasing prevalence of electrical products and the rising safety standards, the demand for the production and testing of thermal protectors is growing daily.

[0060] The first testing mechanism is fixedly mounted on the support frame 2. The first testing mechanism is provided with a first main pressing measuring head 61 and a first auxiliary pressing measuring head 62. The first testing mechanism is adapted to simultaneously drive the first main pressing measuring head 61 through the detection perforation groove on the upper surface of the first heating and conveying assembly 31 to press the outer shell of the thermal protector 100 and drive the first auxiliary pressing measuring head 62 to press the switch contacts of the thermal protector 100.

[0061] The first feeding mechanism is fixedly mounted on the support frame 2. The first feeding mechanism is provided with a first feeding push rod 71. The first feeding mechanism is adapted to drive the first feeding push rod 71 through the discharge trough of the first heating conveying assembly 31 to push the thermal protector 100 located on the first heating conveying channel of the first heating conveying assembly 31 toward the first feeding port 21.

[0062] The transfer receiving mechanism 8 is fixedly mounted on the support frame 2. The transfer receiving mechanism 8 is located between the first heating conveying assembly 31 and the second heating conveying assembly 32. The transfer receiving mechanism 8 is adapted to selectively receive the thermal protector 100 pushed towards the first discharge port 21 by the first feeding mechanism and move it to the path of the second heating conveying channel of the second heating conveying assembly 32.

[0063] The second feeding and pushing mechanism is fixedly mounted on the support frame 2. The second feeding and pushing mechanism is provided with a second feeding push rod 91. The second feeding and pushing mechanism is adapted to drive the second feeding push rod 91 through the second heating and conveying channel of the second heating and conveying assembly 32 to move the thermal protector 100 along the second heating and conveying channel.

[0064] The second detection mechanism 10 is fixedly mounted on the support frame 2. The second detection mechanism 10 is provided with a second main pressing measuring head and a second auxiliary pressing measuring head. The second detection mechanism 10 is adapted to simultaneously drive the second main pressing measuring head through the detection perforation groove on the upper surface of the second heating and conveying assembly 32 to press the outer shell of the thermal protector 100 and drive the second auxiliary pressing measuring head to press the switch contacts of the thermal protector 100.

[0065] The second feeding mechanism 11 is fixedly mounted on the support frame 2. The second feeding mechanism 11 is provided with a second feeding push rod. The second feeding mechanism 11 is adapted to drive the second feeding push rod through the discharge trough of the second heating conveying assembly 32 to push the thermal protector 100 located on the second heating conveying channel of the second heating conveying assembly 32 toward the second feeding port 22.

[0066] The second sorting mechanism is installed on the lower surface of the support frame 2 and is adapted to classify and discharge the thermal protector 100 from the second discharge port 22.

[0067] In this embodiment, as Figure 1 , 2As shown in Figures 5 and 6, the thermal protector 100 first enters the first heating conveying channel of the first heating conveying assembly 31 through the feeding mechanism. Then, the first feeding push rod 51 of the first feeding push mechanism pushes the thermal protector 100 along the first heating conveying channel. When the thermal protector 100 reaches the detection position, the first main pressing measuring head 61 of the first detection mechanism passes through the detection perforation groove and presses against the outer shell of the thermal protector 100. Simultaneously, the first auxiliary pressing measuring head 62 presses against the switch contacts of the thermal protector 100, thus achieving the first stage of detection. After detection, the first unloading push rod 71 of the first unloading mechanism pushes the thermal protector 100 towards the first unloading port 21. If the thermal protector 100 is qualified, the transfer receiving mechanism 8 receives it and transfers it to the path of the second heating conveying channel of the second heating conveying assembly 32. Unqualified thermal protectors 100 fall directly from the first unloading port 21. The qualified thermal protector 100 is pushed by the second feeding push rod 91 of the second feeding push mechanism to the second heating conveying channel of the second heating conveying assembly 32 for the second stage of testing. The second testing mechanism 10 conducts testing in a similar manner. Finally, the second unloading mechanism 11 pushes the thermal protector 100 to the second unloading port 22, and the second sorting mechanism performs the final classification.

[0068] Specifically, the sorting machine also includes a controller. The signal output terminals of the first main pressing measuring head 61 and the first auxiliary pressing measuring head 62 of the first detection mechanism, and the signal output terminals of the second main pressing measuring head and the second auxiliary pressing measuring head of the second detection mechanism 10 are respectively connected to the controller. The controller is connected to the first sorting mechanism and the second sorting mechanism respectively. The controller is adapted to control the action of the first sorting mechanism according to the signal fed back by the first detection mechanism, and to control the action of the second sorting mechanism according to the signal fed back by the second detection mechanism.

[0069] In this embodiment, the controller is a PLC. The first detection mechanism and the second detection mechanism 10 are both electrically connected to the PLC. The PLC controls the corresponding first detection mechanism and the second detection mechanism 10 to determine the on / off state of the thermal protector 100, and then controls the corresponding transfer receiving mechanism 8 and the second sorting mechanism to operate.

[0070] To achieve temperature control of the first heating conveying assembly 31 and the second heating conveying assembly 32, preferably, both the first heating conveying assembly 31 and the second heating conveying assembly 32 are equipped with heating devices (such as resistance wires, heating tubes, or infrared heating lamps) and temperature sensors (such as thermocouples or thermistors). The PLC monitors the temperature values ​​fed back by the temperature sensors in real time and compares them with preset temperature values, thereby controlling the start / stop or power adjustment of the heating devices, thus accurately maintaining the temperatures of the first heating conveying channel and the second heating conveying channel at the set first target temperature and second target temperature, respectively.

[0071] The first and second target temperatures are preset based on the rated operating temperature range of the thermal protector 100 under test. Specifically, the thermal protector 100 typically has a rated operating temperature T_nominal and an allowable tolerance range ±ΔT, thereby defining its lower trigger temperature (T_nominal - ΔT) and upper trigger temperature (T_nominal + ΔT).

[0072] For example, assuming the rated operating temperature T_nominal of the thermal protector 100 is 100°C and its tolerance range ΔT is ±3°C (i.e., its specification may be 100±3°C), then its lower trigger temperature is 97°C and its upper trigger temperature is 103°C. In this case, the first target temperature of the first heating conveying channel of the first heating conveying assembly 31 can be preset to a value T1 lower than the lower trigger temperature (e.g., preset to 95°C) to ensure that the thermal protector 100 should be in its normal conducting state at this temperature (for normally closed thermal protectors). The second target temperature of the second heating conveying channel of the second heating conveying assembly 32 can be preset to a value T2 higher than the upper trigger temperature (e.g., preset to 105°C) to ensure that the thermal protector 100 should have been triggered to the disconnected state at this temperature.

[0073] When the thermal protector 100 is located in the first heating conveying channel (at temperature T1), the first detection mechanism measures the continuity between the common terminal (outer shell) and the normally closed contact of the thermal protector 100. Since temperature T1 is below its lower trigger temperature, it should normally be in a conducting state. If continuity is detected, it is determined to be a qualified product; if non-conductivity is detected, it is determined to be a defective product. Defective products are discharged from the first discharge port 21 of the support frame 2 to the third storage bin 121 by the first feeding mechanism via the first feeding push rod 71. Qualified products continue to be received by the transfer receiving mechanism 8 and conveyed to the second heating conveying channel of the second heating conveying assembly 32.

[0074] When the thermal protector 100 is located in the second heating conveying channel (at temperature T2), the second detection mechanism 10 measures the continuity between the common terminal (casing) of the thermal protector 100 and the normally closed contact. Since temperature T2 is higher than its upper trigger temperature, it should normally be in a non-conductive state. If continuity is detected, it is judged as a defective product; if non-conduction is detected, it is judged as a qualified product. The final test results are then used by the second sorting mechanism to classify and convey the thermal protectors 100 to the next process.

[0075] In addition, corresponding indicator lights are provided on the first and second testing mechanisms 10. A constantly lit indicator light indicates normal operation, and the indicator light turns off when a defective product is detected. The indicator lights are also electrically connected to the PLC, and their on / off state is controlled by the PLC.

[0076] Specifically, such as Figure 1 , 3 As shown, the feeding mechanism includes:

[0077] Vibrating feed plate 41 is mounted on frame 1 and has a feed plate outlet.

[0078] Linear vibrator 42, which is mounted on frame 1;

[0079] A linear feeding trough 43 is installed on a linear vibrator 42. One end of the linear feeding trough 43 is connected to the feeding plate outlet of the vibrating feeding plate 41, and the other end is provided with a feeder outlet.

[0080] Connecting seat 44 is mounted on support frame 2. Connecting seat 44 is provided with a first guide groove 441 that connects to the feeder outlet, a second guide groove that is parallel to the first guide groove 441, and a third guide groove that is connected to and perpendicular to the first guide groove 441 and the second guide groove. The first guide groove 441 is adapted to receive the thermal protector 100 conveyed by the feeder outlet of the straight feeding trough 43.

[0081] A horizontal pushing mechanism is installed on the support frame 2. The horizontal pushing mechanism is equipped with a horizontal push rod. The horizontal push rod is equipped with a thermal protector placement slot 452. The horizontal pushing mechanism is adapted to drive the horizontal push rod to move the thermal protector 100 in the first guide slot 441 along the third guide slot toward the second guide slot.

[0082] The first feeding and pushing mechanism is adapted to drive the first feeding push rod 51 to push the thermal protector 100 located on the second guide groove of the horizontal pushing mechanism into the first heating and conveying channel of the first heating and conveying assembly 31.

[0083] In this embodiment, as Figure 1 , 3As shown, during the feeding process, the vibrating feeding plate 41 vibrates to arrange the thermal protectors 100 in an orderly manner along a preset track and transport them to the feeding plate outlet. The thermal protectors 100 enter the linear feeding trough 43 from the feeding plate outlet. The linear feeding trough 43 generates linear conveying vibration under the action of the linear vibrator 42, transporting the thermal protectors 100 from one end of the linear feeding trough 43 to the feeder outlet at the other end. When the thermal protectors 100 reach the feeder outlet, they are transported to the first guide groove 441 of the connecting seat 44. The three guide grooves on the connecting seat 44 form an "I"-shaped structure, allowing the thermal protectors 100 to turn from the first guide groove 441 to the second guide groove via the third guide groove. The horizontal push rod of the horizontal pushing mechanism is equipped with a thermal protector placement slot 452. Driven by a drive source, the horizontal push rod reciprocates along the third guide groove, pushing the thermal protector 100 in the first guide groove 441 into the second guide groove. The extension and retraction drive source of the horizontal pushing mechanism can be a cylinder. When the thermal protector 100 reaches the second guide groove, the first feeding push rod 51 of the first feeding pushing mechanism pushes the thermal protector 100 from the second guide groove into the first heating conveying channel of the first heating conveying assembly 31, completing the feeding process.

[0088] The second feed push rod 91 is fixedly installed on the slider pair 93, and the push rod 941 of the drive source 94 is fixedly connected to the slider pair 93. The drive source 94 is adapted to drive the slider pair 93 to reciprocate linearly along the slide rail seat 92.

[0089] Specifically, such as Figure 4 As shown, the drive source 94 is a cylinder.

[0090] In this embodiment, as Figure 1 and Figure 4As shown, the slide rail base 92 is mounted on the support frame 2 along a straight direction, providing motion guidance for the slider assembly 93. The slider assembly 93 is slidably engaged with the slide rail base 92 and can slide freely along the slide rail base 92. The drive source 94 is fixedly mounted on one side of the slide rail base 92, and the push rod 941 of the drive source 94 is fixedly connected to the slider assembly 93. When the push rod 941 of the drive source 94 extends or retracts, it drives the slider assembly 93 to reciprocate linearly along the slide rail base 92. The second feed push rod 91 is fixedly mounted on the slider assembly 93 and moves with the slider assembly 93, thereby pushing the thermal protector 100 to the designated position along the second heating conveying channel of the second heating conveying assembly 32.

[0091] Specifically, such as Figure 1 , Figure 1 and Figure 4 As shown, the sorting machine also includes a third storage bin 121, which is placed on the frame 1 and located below the first discharge port 21 of the support frame 2. The third storage bin 121 is adapted to receive the thermal protector 100 that falls from the first discharge port 21 and is not received by the transfer receiving mechanism 8.

[0092] Specifically, such as Figure 1 and Figure 4-5 As shown, the second sorting mechanism includes:

[0093] The sorting drive mechanism 131 is mounted on the lower surface of the support frame 2.

[0094] The sorting cylinder 132 is mounted on the sorting drive mechanism 131. The sorting cylinder 132 includes a first sorting cavity and a second sorting cavity. Both the first sorting cavity and the second sorting cavity are provided with sorting inlets. The sorting inlets of the sorting cylinder 132 are located below the second discharge port 22 of the support frame 2.

[0095] The sorting drive mechanism 131 is adapted to selectively move the sorting cylinder 132 so that the sorting inlet of the first sorting cavity or the second sorting cavity is located below the second discharge port 22.

[0096] Specifically, such as Figure 1 and Figure 7 As shown, the sorting machine also includes a first storage bin 141 and a second storage bin 142. The first storage bin 141 and the second storage bin 142 are placed on the frame 1 and located at the corresponding positions of the outlets of the first sorting chamber and the second sorting chamber of the sorting cylinder 132. The first storage bin 141 is adapted to receive the thermal protector 100 falling from the first sorting chamber, and the second storage bin 142 is adapted to receive the thermal protector 100 falling from the second sorting chamber.

[0097] In this embodiment, as Figure 1-2As shown, the third storage bin 121 is used to sort out defective thermal protectors 100. It is placed on the frame 1 and located directly below the first discharge port 21 of the support frame 2. When a thermal protector 100 is determined to be defective after being detected by the first detection mechanism, it will fall directly from the first discharge port 21 into the third storage bin 121 for collection. The driving component of the sorting drive mechanism 131 can be a cylinder, which is installed on the lower surface of the support frame 2 and is used to control the position movement of the sorting cylinder 132.

[0098] Specifically, such as Figure 1 and Figure 5-6 As shown, the transfer receiving mechanism 8 includes:

[0099] Guide connecting block 81 is fixedly installed on support frame 2. Guide connecting block 81 is provided with a guide channel 811 that connects with the discharge trough of the first heating conveying assembly 31, a vertical through groove 812 that corresponds to the first discharge port 21 of support frame 2, and a feed transition groove 813 that connects with the second heating conveying channel of the second heating conveying assembly 32.

[0100] The receiving mechanism 82 is mounted on the support frame 2. The receiving mechanism 82 is provided with a receiving rod 821. The receiving rod 821 is adapted to selectively actuate to close the vertical through groove 812 of the guide connecting block 81 and receive the thermal protector 100 pushed out from the discharge groove of the first heating conveying assembly 31, and move the received thermal protector 100 in the horizontal direction to the position with the feed transition groove 813.

[0101] The second feeding push mechanism is adapted to push the thermal protector 100 located on the feeding transition groove 813 through the feeding transition groove 813 of the guide connecting block 81 to the second heating conveying channel of the second heating conveying assembly 32 via the second feeding push rod 91 passing through the feeding transition groove 813 of the guide connecting block 81.

[0102] In this embodiment, as Figure 1 and Figure 5-6 As shown, the guide connecting block 81 is fixedly installed on the support frame 2, serving as a transition structure for the thermal protector 100 between different channels. The guide connecting block 81 is provided with: a guide channel 811 directly connected to the discharge chute of the first heating conveying assembly 31, receiving the output of the thermal protector 100; a vertical through-channel 812 corresponding to the first discharge port 21 of the support frame 2, providing a direct falling channel for defective products; and a feeding transition channel 813 connected to the second heating conveying channel of the second heating conveying assembly 32, ensuring that qualified products can continue to the next stage of inspection.

[0103] The receiving mechanism 82 is mounted on the support frame 2 and is driven by a cylinder. The receiving rod 821 can switch between two positions based on the detection results of the first detection mechanism: when the thermal protector 100 is deemed qualified, the receiving rod 821 extends to close the vertical through-slot 812 of the guide connecting block 81, thereby preventing the thermal protector 100 from falling from the first discharge port 21, and receives the thermal protector 100 pushed out from the discharge chute of the first heating conveying assembly 31 and moves it horizontally to the feed transition chute 813; when the thermal protector 100 is deemed unqualified, the receiving rod 821 retracts, allowing the thermal protector 100 to fall directly into the first discharge port 21 through the vertical through-slot 812. The movement control of the receiving rod 821 is performed by a PLC based on the detection results.

[0104] After the thermal protector 100 is successfully transferred to the feeding transition groove 813 by the receiving mechanism 82, the second feeding push rod 91 of the second feeding push mechanism will pass through the feeding transition groove 813 of the guide connecting block 81 and push the thermal protector 100 to the second heating conveying channel of the second heating conveying assembly 32, completing the transition from the first detection stage to the second detection stage.
