[0002] With the development of technology, the manufacturing precision requirements for 3C products are getting higher and higher. For sheet metal parts, the traditional sheet metal thickness inspection usually uses manual measurement or vernier calipers. The measurement accuracy and efficiency are low. When there are many sheets to be inspected, manual measurement may cause visual fatigue and misreading. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a plate thickness detection device to solve the above problems.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A plate thickness detection device includes a worktable and a top plate integrally connected to the worktable. The worktable has a shelf for placing plates. A detection assembly is movably connected below the top plate. The detection assembly includes a travel plate, a pressure plate, a contact sensor, and a displacement sensor. A groove is formed below the travel plate, and the pressure plate is slidably connected within the groove. Multiple springs connect the top of the groove to the upper surface of the pressure plate. When the pressure plate slides down to the bottom, its lower surface is flush with the lower surface of the travel plate. The contact sensor is fixed to the lower surface of the pressure plate, and its contact end is flush with the lower surface of the pressure plate. The displacement sensor is placed on one side of the travel plate to detect its displacement. Both the contact sensor and the displacement sensor are electrically connected to a control panel on the top plate.
[0006] Furthermore, in the above-mentioned utility model, a telescopic cylinder is installed above the top plate, the telescopic end of the telescopic cylinder passes through the top plate and is fixedly connected to the travel plate, and the telescopic cylinder is electrically connected to the control panel.
[0007] Furthermore, in the above-mentioned utility model, the inner walls on the left and right sides of the groove are provided with guide grooves, and the left and right sides of the pressure plate are provided with guide blocks that cooperate with the guide grooves.
[0008] Furthermore, in the above-mentioned utility model, the pressure plate is an acrylic plate.
[0009] Furthermore, in the above-mentioned utility model, a support plate is fixed on one side of the travel plate on the workbench, and the displacement sensor is mounted on the support plate.
[0010] Furthermore, in the above-described utility model, the displacement sensor may be a wire-type displacement sensor.

[0012] The beneficial effects of this utility model are:
[0013] This invention only requires placing the plate on the platform and driving the travel plate and pressure plate downwards via the control panel. When the contact sensor contacts the plate, the displacement distance of the travel plate on the displacement sensor is recorded as 'first'. The travel plate continues to move until it contacts the surface of the platform, and the displacement distance of the travel plate on the displacement sensor is recorded as 'second'. The difference between the two displacements is calculated via the control panel, which is the thickness of the plate. This solution has high measurement accuracy, requires no manual measurement, greatly improves measurement efficiency, and is easy to operate. Attached Figure Description

Detailed Implementation
[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0019] Please see the appendix Figure 1-3As shown, a plate thickness detection device includes a worktable 1 and a top plate 2 disposed above the worktable 1 and integrally connected to the worktable 1. The worktable 1 is provided with a shelf 3 for placing plates, and a detection component for detecting plate thickness is movably connected below the top plate 2.
[0020] The detection assembly includes a travel plate 4, a pressure plate 6, a contact sensor 7, and a displacement sensor 8. A groove 5 is provided below the travel plate 4, and the pressure plate 6 is slidably connected in the groove 5. The pressure plate 6 is used to contact and press against the surface of the plate. Preferably, the pressure plate 6 is an acrylic plate to avoid damaging the plate.
[0021] Multiple springs 9 are connected between the top of the groove 5 and the upper surface of the pressure plate 6. The springs 9 ensure that the lower surface of the pressure plate 6 is always flush with the lower surface of the travel plate 4 before contacting the plate, thus ensuring accuracy during the detection process. That is, under the rebound force of the springs 9, the pressure plate 6 slides down to the bottom and returns to the initial position, with the lower surface of the pressure plate 6 flush with the lower surface of the travel plate 4. The contact sensor 7 is fixed to the lower surface of the pressure plate 6, and the contact end of the contact sensor 7 is also flush with the lower surface of the pressure plate 6, thus avoiding the contact sensor 7 from affecting the accuracy of the actual measurement data. The displacement sensor 8 is placed on one side of the travel plate 4 to detect the displacement of the travel plate 4, and both the contact sensor 7 and the displacement sensor 8 are electrically connected to the control panel 10 set on the top plate 2.
[0022] A telescopic cylinder 11 is installed above the top plate 2. The telescopic end of the telescopic cylinder 11 passes through the top plate 2 and is fixedly connected to the stroke plate 4. The telescopic cylinder 11 is electrically connected to the control panel 10. The stroke plate 4 and the pressure plate 6 are driven to move up and down through the telescopic cylinder 11.
[0023] In the above embodiment, preferably, the inner walls on the left and right sides of the groove 5 are also provided with guide grooves 12, and the left and right sides of the pressure plate 6 are provided with guide blocks 13 that cooperate with the guide grooves 12; secondly, the guide grooves 12 not only guide the movement of the pressure plate 6 and maintain stable movement, but also limit the pressure plate 6. When the guide block 13 slides to the bottom of the guide groove 12, the lower surface of the pressure plate 6 is flush with the lower surface of the travel plate 4.
[0024] In the above embodiments, preferably, a support plate 14 is fixed on one side of the travel plate 4 on the workbench 1, and the displacement sensor 8 is installed on the support plate 14.
[0025] In the above embodiments, preferably, the displacement sensor 8 can be a pull-wire type displacement sensor 8. A connecting block 15 is provided at the bottom of the side of the travel plate 4 near the displacement sensor 8. The connecting block 15 is connected to the pull end of the pull-wire type displacement sensor 8. When the travel plate 4 moves, it drives the connecting block 15 to move. At the same time, the connecting block 15 pulls the pull degree of the displacement sensor 8. The reading of the displacement sensor 8 is the displacement of the travel plate 4.
[0026] Specific work process:
[0027] The workpiece to be tested is placed on the stage 3. The control panel 10 drives the travel plate 4 and the pressure plate 6 to move downwards. When the contact sensor 7 on the pressure plate 6 contacts the workpiece, the contact sensor 7 transmits a signal to the control panel 10. The control panel 10 controls the drive motor to pause for 1 to 3 seconds and records the data of the first displacement sensor 8 (i.e., the displacement distance of the travel plate 4) at this time. Then the drive motor continues to drive the travel plate 4 to continue moving downwards until it contacts the surface of the stage 3 and stops moving. During this process, the pressure plate 6 no longer moves, and the spring 9 is in a compressed state. When the travel plate 4 stops moving, the control panel 10 records the data of the second displacement sensor 8 at this time. The thickness of the workpiece can be obtained by calculating the difference between the two displacement data by the control panel 10. After the test is completed, the drive motor drives the travel plate 4 to move upwards, and the pressure plate 6 automatically returns to the initial position under the action of the spring 9, which is convenient for the next workpiece thickness measurement.
[0028] This solution offers high measurement accuracy, eliminates the need for manual measurement, significantly improves measurement efficiency, and is easy to operate.
