Description

Technical Field

[0001] The present invention relates to the technical field of sweeping machines, and in particular to an LED testing shearing machine for sweeping machines. Background Art

[0002] LEDs, short for semiconductor light-emitting diodes, are light-emitting components made of semiconductor materials that can directly convert electrical energy into light energy and electrical signals into optical signals. Before installing LEDs on a sweeper, they must be tested and their pins trimmed to meet production requirements. Currently, LED testing and trimming are performed manually. This method is non-standard, inefficient, and costly, making it unsuitable for mass production. Furthermore, these procedures are generally based on the operator's experience, making it difficult to achieve a satisfactory result in a single pass. Repeated operations are often required, and improper handling can damage the LEDs, significantly reducing the product's pass rate. Summary of the Invention

[0003] In view of the above, the present invention provides a sweeping machine LED test cutting machine to solve the risk of misjudgment of the sweeping machine LED test, ensure the accurate judgment of the LED test, and at the same time cut the LED pins to meet product installation requirements, greatly improving production efficiency.

[0004] The technical solution of the present invention:

[0005] The present invention provides a sweeper LED test and shearing machine, comprising a frame, a loading and unloading device, an LED tester and a shearing mechanism. The loading and unloading device is installed on the frame for placing LEDs and sending them to the testing station of the LED tester. The LED tester comprises a test host installed on the frame, a positive electrode, a negative electrode, a translation drive device and a clamping drive component. The positive electrode and the negative electrode are electrically connected to the test host respectively to power the LED and output the test results. Two translation drives are installed on the frame, and a clamping drive component is installed at the output end of each translation drive device to The clamping drive member is driven to move horizontally. Two positive electrodes are installed at the output end of one clamping drive member to drive the two positive electrodes to loosen or clamp the positive pins of the LED. Two negative electrodes are installed at the output end of another clamping drive member to drive the two negative electrodes to loosen or clamp the negative pins of the LED. The two translational drive devices respectively drive the two positive electrodes and the two negative electrodes to approach or move away from the shearing station of the shearing mechanism through the corresponding clamping drive members. Two sets of shearing mechanisms are set on the frame to cut the positive pins and negative pins of the tested LED to the required length respectively.

[0006] Furthermore, the loading and unloading device includes a guide rail and a slider slidingly arranged on the guide rail. One end of the guide rail is close to the shearing station of the shearing mechanism to push the slider close to or away from the shearing station of the shearing mechanism. A positioning groove adapted to the LED is provided on the slider to fix the LED lamp head in the positioning groove and to make the positive and negative pins of the LED extend outward respectively and correspond to the positions of the positive electrode and the negative electrode respectively.

[0007] Furthermore, the sweeper LED test and shearing machine also includes a baffle, which is installed on the frame to separate the loading and unloading device from the two positive electrodes, two negative electrodes and the shearing station of the shearing mechanism. An insertion entrance is opened on the baffle at the position of the positioning groove on the slider corresponding to the positioning groove to insert the LED pin in the positioning groove for testing and shearing.

[0008] Furthermore, the LED tester also includes a human-computer interaction interface installed on the rack and electrically connected to the test host.

[0009] Furthermore, the translation drive device includes a translation cylinder and a translation guide mechanism installed on the frame, the piston rod of the translation cylinder is connected to the sliding end of the translation guide mechanism, and the clamping drive member is installed on the sliding end of the translation guide mechanism.

[0010] Furthermore, the translation guide mechanism adopts a module composed of a slide rail and a slider.

[0011] Furthermore, the clamping drive member adopts a clamping cylinder, and two positive electrodes and two negative electrodes are respectively installed on two clamping claws of the corresponding clamping cylinder.

[0012] Furthermore, the shearing mechanism includes a shearing drive device, a first shearing knife and a second shearing knife. The shearing drive device is arranged on the frame to drive the first shearing knife and the second shearing knife to open and close to realize the shearing action.

[0013] Furthermore, the first shearing knife is fixedly mounted on the frame, and the shearing drive device is connected to the second shearing knife to drive the second shearing knife to move closer to or away from the first shearing knife to achieve shearing action.

[0014] Furthermore, the shearing drive device includes a lifting cylinder and a lifting guide mechanism. The lifting cylinder is mounted on the frame through the lifting guide mechanism, and the lifting cylinder drives the second shearing knife to rise and fall and slide through the lifting guide mechanism.

[0015] Beneficial effects of the present invention:

[0016] The LED testing and shearing machine for sweeping machines provided by the present invention uses two clamping drive members to respectively drive two positive electrodes and two negative electrodes to loosen or clamp the positive and negative pins of the LED. In this way, the positive and negative pins of the LED can be automatically clamped to achieve a stable electrical connection, so that the test host can power the LED and output the test results. Two translation drive devices are used to respectively drive the two positive electrodes and two negative electrodes of each clamping drive member to approach or move away from the shearing station of the shearing mechanism. When testing the LED, the two positive electrodes and two negative electrodes are first driven to approach the shearing station of the shearing mechanism so that the positive and negative pins of the LED can be clamped. In this way, when the shearing mechanism performs the shearing action, the two positive electrodes and two negative electrodes can be first driven away from the shearing station of the shearing mechanism, avoiding damage to the positive and negative electrodes when the shearing mechanism is in action. This ensures that the LED testing and the shearing of the LED pins do not interfere with each other, and the two processes are carried out continuously, saving time and improving production efficiency. Two sets of cutting mechanisms are provided to separate the positive pins and negative pins of the LED, which can cut the positive pins and negative pins of the LED into different lengths, so as to facilitate the distinction and installation of the LED on the sweeper.

[0017] The preferred embodiments of the present invention and their beneficial effects will be further described in detail in conjunction with specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0026] See also Figures 1 to 5 The present invention provides a sweeping machine LED test and shearing machine, comprising a frame 1, a loading and unloading device 2, an LED tester 3 and a shearing mechanism 4. The loading and unloading device 2 is installed on the frame 1 for placing the LED and sending it to the test station of the LED tester 3. The LED tester 3 comprises a test host 31 installed on the frame 1, a positive electrode 32, a negative electrode 33, a translation drive device 34, a clamping drive member 35 and an adjustment plate 37. The positive electrode 32 and the negative electrode 33 are electrically connected to the test host 31 respectively to supply power to the LED and output the test results. There are two adjustment plates 37, and the position can be adjusted along the length direction of the LED pin on the frame 1. The two translation drive devices 34 are respectively installed on the two adjustment plates 37. The output end of each translation drive device 34 is installed with a clamping drive member 35 to drive the clamping drive member 35 to move horizontally. Two positive electrodes 32 are mounted on the output end of a clamping driver 35 to drive them to loosen or clamp the positive lead of the LED. Two negative electrodes 33 are mounted on the output end of another clamping driver 35 to drive them to loosen or clamp the negative lead of the LED. Two translational drivers 34, via corresponding clamping drivers 35, respectively drive the two positive electrodes 32 and two negative electrodes 33 toward or away from the shearing station of the shearing mechanism 4. The two shearing mechanisms 4 are mounted on two adjustment plates 37, respectively, to shear the positive and negative leads of qualified LEDs to the desired length.

[0027] The LED testing and shearing machine for sweeping machines provided by the present invention utilizes two clamping actuators 35 to respectively drive two positive electrodes 32 and two negative electrodes 33 to loosen or clamp the positive and negative pins of an LED. This automatically clamps the positive and negative pins of the LED to achieve a stable electrical connection, allowing the test host 31 to power the LED and output test results. Two translational actuators 34 are used to respectively drive the two positive electrodes 32 and two negative electrodes 33 of each clamping actuator 35 toward or away from the shearing station of a shearing mechanism 4. When testing an LED, the two positive electrodes 32 and two negative electrodes 33 are first driven toward the shearing station of the shearing mechanism 4 to clamp the positive and negative pins of the LED. This allows the two positive electrodes 32 and two negative electrodes 33 to be driven away from the shearing station of the shearing mechanism 4 when the shearing mechanism 4 performs the shearing action, preventing damage to the positive electrodes 32 and negative electrodes 33 during the shearing mechanism 4. This allows the LED testing and LED pin shearing to proceed seamlessly without interfering with each other, saving time and improving production efficiency. Two sets of cutting mechanisms 4 are provided to separate the positive pins and the negative pins of the LED, which can cut the positive pins and the negative pins of the LED into different lengths, so as to facilitate the distinction and installation of the LED on the sweeper.

[0028] In this embodiment, the loading and unloading device 2 includes a guide rail 21 and a sliding positioning block 22 slidably mounted on the guide rail 21. One end of the guide rail 21 is positioned adjacent to the shearing station of the shearing mechanism 4, thereby pushing the sliding positioning block 22 toward or away from the shearing station. The sliding positioning block 22 is provided with a positioning slot adapted for the LED, which secures the LED head within the slot and allows the LED's positive and negative leads to extend outward and align with the positive and negative electrodes 32 and 33, respectively. The sliding positioning block 22 is used to push the LED into the shearing station between the two positive and negative electrodes 32, 33, and the shearing mechanism 4, thereby avoiding the potential safety hazards of manual insertion of the LED and improving safety. The sliding positioning block 22 can be manually pushed, preventing the human hand from entering the shearing station between the two positive and negative electrodes 32, 33, and the shearing mechanism 4. Alternatively, the sliding positioning block 22 can be driven automatically by an electric motor.

[0029] To further enhance safety, the LED testing and shearing machine for sweeping robots also includes a baffle 5 , mounted on the frame 1 to separate the loading and unloading device 2 from the two positive electrodes 32 , the two negative electrodes 33 , and the shearing station of the shearing mechanism 4 .

The piston rod of the translation cylinder 341 is connected to the sliding end of the translation guide mechanism 342, and the clamping drive member 35 is mounted on the sliding end of the translation guide mechanism 342. Specifically, the translation guide mechanism 342 utilizes a module composed of a slide rail and a slider, but is not limited thereto.

[0033] In this embodiment, the clamping driving member 35 is a clamping cylinder, and the two positive electrodes 32 and the two negative electrodes 33 are respectively installed on the two clamping claws of the corresponding clamping cylinder.

[0034] In this embodiment, the shearing mechanism 4 includes a shearing drive device 41, a first shearing blade 42, and a second shearing blade 43. The shearing drive device 41 is arranged on the adjustment plate 37 to drive the first shearing blade 42 and the second shearing blade 43 to open and close to achieve the shearing action. Preferably, the first shearing blade 42 is fixedly mounted on the adjustment plate 37, and the shearing drive device 41 is connected to the second shearing blade 43 to drive the second shearing blade 43 to move closer to or away from the first shearing blade 42 to achieve the shearing action. Preferably, the shearing drive device 41 includes a lifting cylinder 411 and a lifting guide mechanism 412. The lifting cylinder 411 is mounted on the adjustment plate 37 through the lifting guide mechanism 412. The lifting cylinder 411 drives the second shearing blade 43 to rise and fall and slide through the lifting guide mechanism 412. Preferably. The lifting guide mechanism 412 includes a guide shaft 4121, a linear bearing 4122, a lifting plate 4123 and a fixed plate 4124. At least two guide shafts 4121 are arranged parallel to each other on the adjustment plate 37. The linear bearing 4122 is fixed on the lifting plate 4123.
