Description

Technical Field

[0001] This invention belongs to the field of power cord production and testing technology, specifically a conductivity testing device for power cord production. Background Technology

[0002] As the core connecting component between electrical equipment and the power supply, the conductivity of the power cord directly determines the safety, stability, and reliability of the power supply. If the conductivity of the power cord is substandard, it will bring a series of safety hazards and quality problems after it is put into use.

[0003] When using existing power cord conductivity testing devices, the insertion of the power plug is generally done manually: the operator needs to hold the power plug manually, align it with the testing socket, and insert it. After the test is completed, the operator needs to manually unplug the plug.

[0004] The aforementioned existing conductivity testing devices for power cord production require operators to repeatedly perform cyclical actions such as plugging and unplugging. Long-term repetitive work can easily lead to hand fatigue, and under fatigue, it is easy to cause delayed plugging or unplugging or improper plugging, which reduces the accuracy of conductivity testing in power cord production and thus reduces the conductivity efficiency of power cord production.

[0005] Therefore, the present invention provides a conductivity testing device for power cord production. Summary of the Invention

[0006] In order to overcome the shortcomings of existing technologies and solve the problem mentioned in the background technology that long-term repetitive work can easily lead to hand fatigue and increase the workload of operators.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a conductivity testing device for power cord production, comprising a housing, a socket fixedly connected to the surface of the housing, a groove provided inside the socket, a positioning frame and a fixing frame provided from the inside to the outside on one side of the socket, a clamping block slidably connected to the surface of the positioning frame, a sliding groove slidably connected to the surface of the clamping block, a moving block slidably connected to the inside of the fixing frame, a moving frame slidably connected to the inside of the moving block, a push plate slidably connected to the inside of the moving frame, and a first limiting rod fixedly connected to the inside of the push plate, one end of the first limiting rod being slidably connected to the inner wall of the sliding groove.

[0008] Preferably, a lead screw is rotatably connected inside the fixed frame, and the lead screw and the moving rod are internally threaded together. A motor is fixedly connected to one side of the fixed frame, and the output end of the motor is fixedly connected to one end of the lead screw.

[0009] Preferably, an electric cylinder is fixedly connected to the upper surface of the positioning frame, a push block is fixedly connected to the telescopic end of the electric cylinder, and a discharge groove is provided on the surface of the positioning frame.

[0010] Preferably, a first spring is fixedly connected between the movable block and the movable frame, and a second spring is fixedly connected between the push plate and the movable frame.

[0011] Preferably, the slide groove has a first insertion hole inside, and a second insertion hole is provided on one side of the first insertion hole. The first insertion hole is located inside the slide groove, and the size of the first insertion hole matches the size of the first limiting rod.

[0012] Preferably, a limiting frame is fixedly connected to one side of the fixing frame, the limiting frame has a first limiting groove inside, a protrusion is fixedly connected to the lower surface of the limiting frame, and a second limiting groove is provided inside the protrusion.

[0013] Preferably, the first limiting groove includes a feeding section, a replacement section is provided on one side of the feeding section, a discharge section is provided on one side of the replacement section, a reset section is provided on one side of the discharge section, and the groove depth of the feeding section is less than the groove depth of the discharge section.

[0014] Preferably, a first electromagnet is fixedly connected inside the reset section, and a second electromagnet is fixedly connected inside the replacement section. The first limiting rod is made of magnetic material, and both the first and second electromagnets magnetically attract the first limiting rod after being energized.

[0015] Preferably, the second limiting groove includes a horizontal section, a rising section is provided on one side of the horizontal section, a falling section is provided on one side of the rising section, and an insertion section is provided on one side of the falling section.

[0016] Preferably, a second limiting rod is fixedly connected to the surface of the first limiting rod, the second limiting rod and the second limiting groove are slidably connected inside, and a wedge is fixedly connected inside the descending section.

[0017] The beneficial effects of this invention are as follows: 1. The conductivity testing device for power cord production described in this invention is equipped with a push plate and a clamping block. When automatic loading and testing of power plugs and sockets is required, the push plate can be driven to move, and the push plate pushes the clamping block to slide synchronously. The clamping block fixes the power plug, and the push plate pushes behind the power plug, so that the power plug and the clamping block can slide stably on the positioning frame. This allows the power plug to be automatically placed inside the socket for testing. This device automatically completes the plug and socket insertion action by driving the push plate to slide the clamping block, eliminating the need for manual insertion. This avoids the problem of repeated manual insertion, which increases the labor intensity of workers, and the problem of insufficient insertion of the socket and plug, which leads to the testing equipment misjudging the conductivity of the power cord, thus reducing the testing efficiency. 2. The conductivity testing device for power cord production described in this invention includes a push plate and a clamping block. When the push plate pushes the power plug into the socket, it activates a second electromagnet. The second electromagnet attracts a first limiting rod, causing the first limiting rod to rise and disengage from the first socket. Subsequently, the first limiting rod slides in a groove to the second socket, and the push plate moves to the groove, positioned on the other side of the power plug. After the test is completed, the push plate is driven to push the power plug out of the socket. This device directly drives the push plate to push the plug out of the socket after the insertion test is completed, eliminating the need for manual insertion and removal. This reduces manual operation and avoids the problem in existing devices where manual removal of the plug increases the workload of workers, reduces material handling efficiency, and consequently reduces testing efficiency. 3. The conductivity testing device for power cord production described in this invention releases the power cord from its fixing operation by pushing the power plug out and moving it to the discharge trough. The power plug can then be discharged through the discharge trough. The user can screen the power plugs according to the test results. This device can automatically discharge the power plugs after testing without the need for manual clamping and material handling, thus improving the testing efficiency of the power plugs.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0020] like Figures 1 to 10 As shown in the embodiment of the present invention, a conductivity testing device for power cord production includes a housing 1. A socket 11 is fixedly connected to the surface of the housing 1. A groove 111 is provided inside the socket 11. A positioning frame 2 and a fixing frame 3 are provided on one side of the socket 11 from the inside to the outside. A clamping block 23 is slidably connected to the surface of the positioning frame 2. A moving groove is provided on the positioning frame 23. The clamping block 23 is limited to sliding inside the moving groove. A sliding groove 233 is slidably connected to the surface of the clamping block 23. A moving block 33 is slidably connected to the inside of the fixing frame 3. A moving frame 34 is slidably connected to the inside of the moving block 33. A push plate 36 is slidably connected to the inside of the moving frame 34. A first limiting rod 361 is fixedly connected to the inside of the push plate 36. One end of the first limiting rod 361 is slidably connected to the inner wall of the sliding groove 233.

[0021] like Figure 3As shown, a lead screw 31 is rotatably connected inside the fixed frame 3. The lead screw 31 and the moving rod are internally threaded together. A motor 32 is fixedly connected to one side of the fixed frame 3. The output end of the motor 32 is fixedly connected to one end of the lead screw 31.

[0022] like Figure 4 As shown, an electric cylinder 22 is fixedly connected to the upper surface of the positioning frame 2, and a push block is fixedly connected to the telescopic end of the electric cylinder 22.

[0023] like Figure 6 As shown, a first spring 35 is fixedly connected between the movable block 33 and the movable frame 34, and a second spring 363 is fixedly connected between the push plate 36 and the movable frame 34.

[0024] like Figure 7 As shown, a first insertion hole 231 is provided inside the slide groove 233, and a second insertion hole 232 is provided on one side of the first insertion hole 231. The first insertion hole 231 is located inside the slide groove 233, and the size of the first insertion hole 231 matches the size of the first limiting rod 361.

[0025] like Figures 8 to 10 As shown, a limiting frame 4 is fixedly connected to one side of the fixed frame 3. The limiting frame 4 has a first limiting groove 43 inside. A protrusion 44 is fixedly connected to the lower surface of the limiting frame 4. A second limiting groove 45 is provided inside the protrusion 44. A discharge groove 21 is provided on the surface of the positioning frame 2. The first limiting groove 43 includes a feeding section 431. A replacement section 432 is provided on one side of the feeding section 431. A second electromagnet is fixedly connected inside the replacement section 432. The first limiting rod 361 is made of magnetic material. When energized, both the first electromagnet 41 and the second electromagnet magnetically attract the first limiting rod 361. The second limiting groove 45 includes a horizontal section 451. A rising section 452 is provided on one side of the horizontal section 451.

[0026] Specifically, existing power cord conductivity testing devices typically require manual operation when inserting the power plug: the operator must manually hold the power plug and align it with the testing socket 11 to complete the insertion. Since the operator needs to repeatedly perform the insertion and removal cycles, long-term repetitive work can easily lead to hand fatigue. Furthermore, under fatigue, the plug may be inserted or removed too late or not properly inserted, resulting in a decrease in the conductivity accuracy of the power cord and thus a decrease in the conductivity efficiency of the power cord production.

[0027] To avoid the above problems, this device is used as follows: When using this device, the clamp 23 fixes the power plug, then the motor 32 is turned on, the motor 32 turns the lead screw 31 to rotate, the lead screw 31 drives the moving block 33 to slide inside the fixed frame 3, the moving block 33 drives the moving frame 34 to slide synchronously, the moving frame 34 drives the push plate 36 to slide synchronously, at this time the push plate 36 is in front of the power plug, one end of the first limiting rod 361 is in the first socket 231, the other end of the first limiting rod 361 is in the feeding section 431 in the first limiting groove 43, and the second limiting rod 362 is in the horizontal section 451. When the moving frame 34 drives the push plate 36 to move, the push plate 36 pushes the clamp 23 to slide in the positioning frame 2 through the first limiting rod 361. The clamp 23 positions the power plug and follows the push plate 36 to push one side of the power plug, so that the plug moves to the socket 11 and is inserted into the socket 11. After the first limit rod 361 makes full contact with the plug, it moves to the interface between the feeding section 431 and the replacement section 432. The second electromagnet, after being energized, attracts the first limit rod 361. The first limit rod 361 drives the push plate 36 to move upward. The first limit rod 361 first disengages from the first socket 231 and moves into the interior of the slide groove 233. Then the second limit rod 362 moves upward and slides in the horizontal section 451 to the rising section 452. The second limit block is squeezed by the inclined surface of the protrusion 44, causing the first limit rod 361 to slide away from the first socket 231 in the slide groove 233. The first limit rod 361 slides during replacement, causing the push plate 36 to move away from the plug. At this time, the push plate 36 moves away from the plug and slides on one side of the plug. The moving frame 34 continues to drive the push plate 36 to slide, causing the first limit rod 361 to slide in the slide groove 233. At the same time, the first limit rod 361 slides in the replacement section 432. When the first limiting rod 361 moves to the interface between the replacement section 432 and the feeding section 431, the first limiting rod 361 is directly above the second socket 232, the push plate 36 is in the groove 111 inside the socket 11, the second electromagnet releases the attraction of the first limiting rod 361, so that the second spring 363 drives the first limiting rod 361 to descend, the first limiting rod 361 drives the second limiting rod 362 to descend, the second limiting rod 362 slides in the descending section 453, so that the first limiting rod 361 drives the push plate 36 to slide to one side of the plug, and the first limiting rod 361 enters the interior of the second socket 232; When the test is completed and the plug needs to be unplugged, the moving frame 34 can be driven to reset. The moving frame 34 drives the push plate 36 to reset. The push plate 36 and the clamping block 23 cooperate to push the plug out of the socket 11. At this time, the first limit rod 361 is in the unloading section 433, and the automatic plugging and unplugging operation of the plug can be completed.

[0028] This device drives the push plate 36 to slide the clamping block 23, which can automatically complete the insertion and removal of the plug and socket 11 without manual intervention. This reduces manual operation and avoids the problems in existing devices where manual removal of the plug increases the workload of workers, reduces the efficiency of material handling, and thus reduces the detection efficiency. It also avoids the problem that insufficient insertion of the socket 11 and plug can lead to the detection equipment misjudging the conductivity of the power cord, thus reducing the detection efficiency. Example

[0029] like Figures 8 to 10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a feeding section 433 is provided on one side of the replacement section 432, a reset section 434 is provided on one side of the feeding section 433, and the groove depth of the feeding section 431 is less than the groove depth of the feeding section 433.

[0030] like Figure 9 As shown, a first electromagnet 41 is fixedly connected inside the reset section 434, a descending section 453 is provided on one side of the rising section 452, an insertion section 455 is provided on one side of the descending section 453, a second limiting rod 362 is fixedly connected to the surface of the first limiting rod 361, the second limiting rod 362 and the second limiting groove 45 are slidably connected inside, and a wedge block 454 is fixedly connected inside the descending section 453.

[0031] Specifically, when using the conductivity testing device for the aforementioned power cord, the clamp 23 can position and feed the plug. After the test is completed, the clamp 23 is difficult to open and close automatically to load and unload the plug, so manual operation is required. This increases the labor intensity of the staff, and the slow speed of manual clamp release leads to the accumulation of plugs after the test, which slows down the overall testing cycle and causes a decrease in testing efficiency.

[0032] To avoid the aforementioned technical problems, the device is improved as follows: After the detection is completed, the second limiting rod 362 slides in the descending section 453, and the first limiting rod 361 slides in the feeding section 431. When the second limiting rod 362 moves to the wedge block 454, the wedge block 454 presses against the second limiting rod, causing the first limiting rod 361 to move from the feeding section 431 to the descending section. This causes the first limiting rod 361 to drive the clamping block 23 to slide on the positioning frame 2. The clamping block 23 slides at the discharge chute 21, causing the clamping block 23 to move away from the plug. Block 23 releases the plug from its fixation. The plug is subjected to gravity and automatically completes the unloading operation. When the first limiting rod 361 moves to the interface between the unloading section 433 and the reset section 434, the first electromagnet 41 is energized and continues to attract the first limiting rod 361. The first limiting rod 361 moves upward, causing the second limiting rod 362 to move from the descending section 453 to the insertion section 455. The second limiting rod 362 is squeezed by the protrusion 44 again, causing the first limiting rod 361 to disengage from the inside of the second insertion hole 232 and move into the slide groove 233. When the first limiting rod 361 moves to the interface between the reset section 434 and the feeding section 431, the first electromagnet 41 releases its attraction to the first limiting rod 361, the first limiting rod 361 descends, the first limiting rod 361 enters the interior of the first insertion hole 231, and pushes the clamping block 23 to fix the plug again, thus completing the detection operation again. Then, the electric cylinder 22 can be driven to work, and the electric cylinder 22 pushes the next plug to the clamping position.

[0033] This device can automatically unload the power plugs after testing, eliminating the need for manual clamping and unloading, thus improving the testing efficiency of power plugs.

[0034] Working principle: When using this device, clamp 23 fixes the power plug, then motor 32 is turned on, motor 32 turns lead screw 31 to rotate, lead screw 31 drives moving block 33 to slide inside fixed frame 3, moving block 33 drives moving frame 34 to slide synchronously, moving frame 34 drives push plate 36 to slide synchronously. At this time, push plate 36 is in front of power plug, one end of first limiting rod 361 is in the first socket 231, the other end of first limiting rod 361 is in the feeding section 431 in first limiting groove 43, and second limiting rod 362 is in horizontal section 451. When moving frame 34 drives push plate 36 to move, push plate 36 pushes clamp 23 to slide in positioning frame 2 through first limiting rod 361. Clamp 23 positions power plug and follows push plate 36 to push one side of power plug, so that plug moves to socket 11 and is inserted into socket 11. When socket 11 and plug are connected After sufficient contact, the first limiting rod 361 moves to the interface between the feeding section 431 and the replacement section 432. The second electromagnet, after being energized, attracts the first limiting rod 361. The first limiting rod 361 drives the push plate 36 to move upward. The first limiting rod 361 first disengages from the first insertion hole 231 and moves into the interior of the slide groove 233. Then the second limiting rod 362 moves upward and slides in the horizontal section 451 to the rising section 452. The second limiting block is squeezed by the inclined surface of the protrusion 44, causing the first limiting rod 361 to slide away from the first insertion hole 231 in the slide groove 233. The first limiting rod 361 slides during replacement, causing the push plate 36 to move away from the plug. At this time, the push plate 36 moves away from the plug and slides on one side of the plug. The moving frame 34 continues to drive the push plate 36 to slide, causing the first limiting rod 361 to slide in the slide groove 233. At the same time, the first limiting rod 361 slides in the replacement section 432. When the first limiting rod 361 moves to the interface between the replacement section 432 and the feeding section 431, the first limiting rod 361 is directly above the second socket 232, the push plate 36 is in the groove 111 inside the socket 11, the second electromagnet releases the attraction of the first limiting rod 361, so that the second spring 363 drives the first limiting rod 361 to descend, the first limiting rod 361 drives the second limiting rod 362 to descend, the second limiting rod 362 slides in the descending section 453, so that the first limiting rod 361 drives the push plate 36 to slide to one side of the plug, and the first limiting rod 361 enters the interior of the second socket 232; When the test is completed and the plug needs to be unplugged, the moving frame 34 can be driven to reset. The moving frame 34 drives the push plate 36 to reset. The push plate 36 and the clamping block 23 cooperate to push the plug out of the socket 11. At this time, the first limit rod 361 is in the unloading section 433, and the automatic plugging and unplugging operation of the plug can be completed. After the test is completed, the second limiting rod 362 slides in the descending section 453, and the first limiting rod 361 slides in the feeding section 431. When the second limiting rod 362 moves to the wedge block 454, the wedge block 454 squeezes the second limiting rod, causing the first limiting rod 361 to move from the feeding section 431 to the descending section. This causes the first limiting rod 361 to drive the clamping block 23 to slide on the positioning frame 2. The clamping block 23 slides at the discharge chute 21, causing the clamping block 23 to move away from the plug and release its grip on the plug. When the plug is under gravity and automatically completes the feeding operation, when the first limiting rod 361 moves to the interface between the feeding section 433 and the reset section 434, the first electromagnet 41 is energized and continues to attract the first limiting rod 361. The first limiting rod 361 moves upward, causing the second limiting rod 362 to move from the descending section 453 to the insertion section 455. The second limiting rod 362 is squeezed by the protrusion 44 again, causing the first limiting rod 361 to disengage from the inside of the second socket 232 and move into the slide groove 233. When the first limiting rod 361 moves to the interface between the reset section 434 and the feeding section 431, the first electromagnet 41 releases its attraction to the first limiting rod 361, the first limiting rod 361 descends, the first limiting rod 361 enters the interior of the first insertion hole 231, and pushes the clamping block 23 to fix the plug again, thus completing the detection operation again. Then, the electric cylinder 22 can be driven to work, and the electric cylinder 22 pushes the next plug to the clamping position.
