Description

Technical Field

[0001] This utility model relates to the field of testing platforms, specifically a PLC controller testing platform device. Background Technology

[0002] A PLC, also known as a programmable logic controller, is a digital electronic system designed specifically for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog inputs and outputs.

[0003] After the PLC controller is manufactured, to ensure its stable and efficient operation in various complex industrial environments, comprehensive and accurate performance testing is required. Test platforms typically have internal signal source simulation modules that generate various types of analog and digital signals. These signals serve as inputs to the PLC controller, simulating signals provided by sensors, switches, and other equipment in the industrial field. During testing, the module data cables on the test platform need to be connected to the PLC controller. The signal source module within the test platform inputs various test drive data into the PLC controller via data cables. The PLC controller then feeds back its internal operating data to the test platform, allowing operators to determine whether the PLC controller's operating data meets production standards from the display screen on the test platform.

[0004] When performing performance testing on a PLC controller using existing testing platform equipment, personnel need to install one end of a specific data cable into the data input port on the testing platform equipment and connect the other end to the data receiving port on the PLC controller. This results in personnel constantly searching for a matching data cable among numerous data cables during performance testing, increasing the workload of personnel performing performance testing on the PLC controller. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a PLC controller testing platform device to solve the technical problem that the data lines on the surface of the testing platform are messy due to the lack of data line collection equipment in the existing testing platform devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PLC controller testing platform device, comprising a testing platform body, a data cable being provided inside the testing platform body, a take-up assembly being installed at the end of the data cable, the take-up assembly including a take-up coil, a rotating rod being fixed to one side of the take-up coil, a serrated disk being connected to the outer wall of the rotating rod, a driving block being provided on the inner wall of the serrated disk, a rotating plate being connected to one side of the driving block, a driving plate being provided at the end of the rotating plate, and a rotating block being movably mounted at the end of the driving plate.

[0007] By adopting the above technical solution, the technical problem of messy data cables on the surface of the test platform caused by the lack of data cable collection equipment in the existing test platform device is solved. After the PLC controller completes the performance test, the knob drives the first bevel gear to rotate through the first adjusting rod. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the speed gear set to rotate through the second adjusting rod, so that the rotating block drives the rotating plate to rotate and swing through the drive plate. At the same time, the drive block on one side of the rotating plate drives the saw tooth disk to rotate by pushing the saw tooth on the inner wall of the saw tooth disk. The saw tooth disk drives the take-up coil to retract the data cable through the rotating rod.

[0008] The present invention is further configured such that the inner wall of the sawtooth disk is provided with sawtooth, and one end of the drive block is snapped into the inside of the sawtooth.

[0009] By adopting the above technical solution, when the rotating plate drives the drive block to move, the drive block drives the sawtooth disk to rotate by squeezing the sawtooth on the inner wall of the gear disk.

[0010] The present invention is further configured such that a connecting rod is fixed on one side of the driving block, and the driving block is movably mounted on one side of the rotating plate through the connecting rod, and the rotating plate is sleeved on the outer wall of the rotating rod.

[0011] By adopting the above technical solution, when the rotating rod rotates, the rotating plate does not rotate due to the fixation of the driving plate, so that the driving block rotates and swings around the connecting rod as the center. When the saw tooth disk stops rotating, the driving block is once again locked into the saw teeth on the inner wall of the saw tooth disk.

[0012] The present invention is further configured such that a knob is provided on the top of the main body of the test platform, a first adjusting rod is connected to the bottom end of the knob, a first bevel gear is installed at the end of the first adjusting rod, a second bevel gear is connected to one side of the first bevel gear, and a second adjusting rod is fixed to one side of the second bevel gear.

[0013] By adopting the above technical solution, rotating the knob causes the first bevel gear to rotate via the first adjusting rod. The first bevel gear then drives the second bevel gear to rotate, and the rotating second bevel gear drives the gear train to operate via the second adjusting rod.

[0014] The present invention is further configured such that a speed-changing gear set is installed at the end of the rotating block, and the end of the speed-changing gear set is connected to a second adjusting rod.

[0015] By adopting the above technical solution, the speed change gear set increases the speed transmitted by the second adjusting rod, thereby speeding up the rotation of the rotating block.

[0016] The present invention is further configured such that a connector is installed at the end of the data cable, and the connector is used to install and fix the data cable on the PLC controller.

[0017] By adopting the above technical solution, when the data cable is pulled out from the inside of the test platform body, the data cable is connected to the PLC controller through the connector at the end, so that the test data commands inside the test platform body can be input to the PLC controller through the data cable.

[0018] The present invention is further configured such that a control panel is installed on the top of the main body of the test platform, and a display screen is provided on one side of the main body of the test platform.

[0019] By adopting the above technical solution, before conducting performance tests on the PLC controller, staff can adjust the test data through the control panel and simultaneously view the PLC controller test results on the display screen.

[0020] The present invention is further configured such that a wire block is fixed on one side of the main body of the test platform, and the wire block is sleeved on the outer wall of the data cable.

[0021] By adopting the above technical solution, the conductor block has a certain degree of elasticity, which reduces the contact wear between the data cable and the surface of the test platform during the pulling process.

[0022] The present invention is further provided that the outer wall of the knob is provided with anti-slip texture.

[0023] By adopting the above technical solution, the anti-slip texture on the surface of the knob can increase the friction between the finger and the knob, preventing the finger from slipping when rotating the knob.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model solves the technical problem of messy data cables on the surface of the test platform due to the lack of data cable collection equipment in existing test platform devices by setting up a test platform body, a rotating block, a drive plate, a rotating plate, a drive block, a sawtooth disk, and a take-up coil. After the PLC controller completes the performance test, the knob drives the first bevel gear to rotate through the first adjustment rod. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the speed gear set to rotate through the second adjustment rod, so that the rotating block drives the rotating plate to rotate and swing through the drive plate. At the same time, the drive block on one side of the rotating plate drives the sawtooth disk to rotate by pushing the sawtooth on the inner wall of the sawtooth disk. The sawtooth disk drives the take-up coil to retract the data cable through the rotating rod.

[0026] 2. This utility model, by setting a knob, a first adjusting rod, a first bevel gear, a second bevel gear, a second adjusting rod, and a speed-changing gear set, allows the PLC controller to rotate after completing the performance test. The knob, through the first adjusting rod, drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The rotating second bevel gear, through the second adjusting rod, drives the speed-changing gear set to operate, thereby providing power to the take-up assembly. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1

[0037] A PLC controller testing platform device, such as Figure 1 - Figure 5 As shown, the device includes a test platform body 1. Inside the test platform body 1, a data cable 501 is installed. A take-up assembly is installed at the end of the data cable 501. The take-up assembly includes a take-up coil 5. A rotating rod 401 is fixed to one side of the take-up coil 5. A serrated disk 4 is connected to the outer wall of the rotating rod 401. A driving block 305 is installed on the inner wall of the serrated disk 4. A rotating plate 303 is connected to one side of the driving block 305. A driving plate 302 is installed at the end of the rotating plate 303. The rotating block 301 is movably mounted at the end of the driving plate 302. This design solves the problem of existing test platform devices lacking a data cable collection device, resulting in a large number of data cables on the test platform surface. In the event of a technical issue, after the PLC controller completes its performance test, knob 2 drives the first bevel gear 202 to rotate via the first adjusting rod 201. The first bevel gear 202 drives the second bevel gear 203 to rotate. The second bevel gear 203 drives the gear set 3 to rotate via the second adjusting rod 204. This causes the rotating block 301 to rotate and swing via the drive plate 302. At the same time, the drive block 305 on one side of the rotating plate 303 drives the sawtooth disk 4 to rotate by pushing the sawtooth on the inner wall of the sawtooth disk 4. The sawtooth disk 4 drives the take-up coil 5 to retract the data cable 501 via the rotating rod 401.

[0038] Please see Figure 4 The inner wall of the sawtooth disk 4 is provided with sawtooths, and one end of the drive block 305 is snapped into the inside of the sawtooths. When the rotating plate 303 drives the drive block 305 to move, the drive block 305 drives the sawtooth disk 4 to rotate by squeezing the sawtooths on the inner wall of the gear disk 4.

[0039] Please see Figure 4 A connecting rod 304 is fixed on one side of the drive block 305, and the drive block 305 is movably mounted on one side of the rotating plate 303 through the connecting rod 304. The rotating plate 303 is sleeved on the outer wall of the rotating rod 401. When the rotating rod 401 rotates, the rotating plate 303 does not rotate due to the fixation of the drive plate 302, so that the drive block 305 rotates and swings around the connecting rod 304 as the center. When the saw tooth disk 4 stops rotating, the drive block 305 is once again engaged in the saw teeth on the inner wall of the saw tooth disk 4.

[0040] Please see Figure 1 and Figure 3 The test platform body 1 has a knob 2 on its top. The bottom of the knob 2 is connected to a first adjusting rod 201. A first bevel gear 202 is installed at the end of the first adjusting rod 201. A second bevel gear 203 is connected to one side of the first bevel gear 202. A second adjusting rod 204 is fixed to one side of the second bevel gear 203. When the knob 2 is rotated, the knob 2 drives the first bevel gear 202 to rotate through the first adjusting rod 201. The first bevel gear 202 drives the second bevel gear 203 to rotate. The rotating second bevel gear 203 drives the gear set 3 to rotate through the second adjusting rod 204.

[0041] Please see Figure 3 The end of the rotating block 301 is equipped with a speed-changing gear set 3, and the end of the speed-changing gear set 3 is connected to the second adjusting rod 204. The speed-changing gear set 3 increases the speed transmitted by the second adjusting rod 204, thereby speeding up the rotation of the rotating block 301.

[0042] Please see Figure 3 The data cable 501 is equipped with a connector 502 at its end, and the connector 502 is used to fix the data cable 501 on the PLC controller. When the data cable 501 is pulled out from the inside of the test platform body 1, the data cable 501 is connected to the PLC controller through the connector 502 at its end, so that the test data instructions inside the test platform body 1 can be input to the PLC controller through the data cable 501.

[0043] Please see Figure 1 The test platform body 1 is equipped with a control panel 101 on its top and a display screen 102 on one side. Before the PLC controller is tested, the staff can adjust the test data through the control panel 101 and can also see the test results of the PLC controller on the display screen 102.

[0044] Please see Figure 2 A wire block 103 is fixed on one side of the test platform body 1, and the wire block 103 is sleeved on the outer wall of the data cable 501. The wire block 103 has a certain elasticity, which reduces the contact wear between the data cable 501 and the surface of the test platform body 1 during the pulling process.

[0045] Please see Figure 2 The outer wall of the knob 2 is provided with anti-slip texture. The anti-slip texture on the surface of the knob 2 can increase the friction between the finger and the knob 2 and prevent the finger from slipping when rotating the knob 2.

[0046] Example 2

[0047] A PLC controller testing platform device, such as Figure 6As shown, the technical solution and parts of this embodiment are basically the same as those of Embodiment 1. The technically similar parts will not be described again here. The difference is that a motor 6 is installed at the end of the rotating block 301, and the output end of the motor 6 drives the rotating block 301 to rotate. The installation of the motor 6 eliminates the need for the operator to manually rotate the knob 2 to drive the rotating block 301 to rotate.

[0048] The working principle of this utility model is as follows: First, a set of data cables 501 is pulled out from the inside of the test platform body 1. The data cables 501 are connected to the PLC controller through the connector 502 at the end. During the pulling out of the data cables 501, the end of the data cables 501 drives the take-up coil 5 to rotate. One side of the take-up coil 5 is connected to the sawtooth disk 4 through the rotating rod 401. The rotation of the take-up coil 5 causes the sawtooth disk 4 to rotate synchronously. During the rotation of the sawtooth disk 4, the driving block 305 connected to the inner wall of the sawtooth disk 4 slides along the sawtooth surface on the inner wall of the sawtooth disk 3. Since the sawtooth depth on the inner wall of the sawtooth disk 3 is shallow, the driving block 305 rotates and swings around the connecting rod 304. When the sawtooth disk 4 stops rotating, the driving block 305 is locked into the sawtooth on the inner wall of the sawtooth disk 4 again. The signal testing module inside the test platform body 1 inputs the test signal to the PLC controller through the data cable 501. The data running in the PLC controller is then fed back to the test platform body 1 through the data cable 501. After the C controller completes the performance test, it rotates knob 2. Knob 2 drives the first bevel gear 202 to rotate via the first adjusting rod 201. The first bevel gear 202 drives the second bevel gear 203 to rotate. The rotating second bevel gear 203 drives the gear set 3 to rotate via the second adjusting rod 204. The gear set 3 increases the speed transmitted by the second adjusting rod 204, thereby accelerating the rotation of the rotating block 301. The rotating block 301 is driven by the drive plate 302 movably connected to its end. The rotating plate 303 rotates and swings on the rotating rod 401. When the rotating block 301 rotates to the right, the driving plate 302 pulls the rotating plate 303 to swing to the right, so that the driving block 305 connected to one side of the rotating plate 303 slides on the saw tooth surface on the inner wall of the saw tooth disk 4 and falls into the next set of saw teeth. At the same time, the driving block 305 on one side of the rotating plate 303 drives the saw tooth disk 4 to rotate by pushing the saw teeth on the inner wall of the saw tooth disk 4. The saw tooth disk 4 drives the take-up coil 5 to retract the data cable 501 through the rotating rod 401.
