[0053] The embodiments of the present application disclose a detection platform mechanism.

[0054] Please refer to Figure 1 An embodiment of the detection platform mechanism provided in the embodiments of the present application includes:

[0055] The platform frame, the detection base plate 1, the limiting mechanism 4 and the electric adjusting mechanism 3.

[0056] The first side edge of the detection base plate 1 is rotatably connected to the platform frame through the first rotating shaft 11. The rotating connection means in the form of rotating shaft is an existing means, which will not be described here.

[0057] The limiting mechanism 4 is installed on the front surface of the detection base plate 1, and is used for limiting the to-be-detected plate 5 located on the front surface of the detection base plate 1, so as to avoid the to-be-detected plate 5 from sliding downward when it is inclined at a certain angle, thereby affecting the detection.

[0058] The electric adjusting mechanism 3 is installed on the platform frame and connected with the detection base plate 1, and is used for driving the detection base plate 1 to rotate around the first rotating shaft 11 between the horizontal state and the preset inclined angle state. It can be understood that, under the driving of the electric adjusting mechanism 3, the detection base plate 1 can be adjusted to rotate between 0° and the preset inclined angle.

[0059] The detection platform mechanism designed in the present application rotatably connects the first side edge of the detection base plate 1 to the platform frame through the first rotating shaft 11, so that it can be adjusted to rotate around the first rotating shaft 11. The electric adjusting mechanism 3 is connected with the detection base plate 1, and the inclination angle of the detection base plate 1 is adjusted by driving the detection base plate 1 to rotate. The to-be-detected plate 5 is detected in a certain inclined angle, which can greatly reduce the labor intensity of the detection personnel and improve the detection efficiency compared with the flat detection mode. Moreover, the angle adjusting mode is in the form of electricity, which is simple and convenient to adjust, and is helpful to further save manpower.

[0060] The above is an embodiment of the detection platform mechanism provided in the embodiments of the present application, and the following is an embodiment of the detection platform mechanism provided in the embodiments of the present application, please refer to Figures 1 to 5 .

[0061] Based on the scheme of the above embodiment one:

[0062] Further, as shown in the figure, for the design of the electric adjusting mechanism 3, including the adjusting driver 31, the straight rack 34 and the gear piece 32. Figure 2

[0063] The straight rack 34 is rotatably connected to the detection base plate 1 at one end; the output shaft of the adjusting driver 31 is connected with the gear piece 32 for driving the gear piece 32 to rotate; the gear piece 32 is engaged with the tooth structure of the straight rack 34.

[0064] A limiting sliding block 33 is rotatably installed on the platform frame at one side of the gear piece 32; the rotation center line of the limiting sliding block 33 is parallel to the rotation center line of the gear piece 32; the limiting sliding block 33 is provided with a sliding groove for the straight rack 34 to pass through and be slidingly connected with the straight rack 34; the straight rack 34 is located between the gear piece 32 and the limiting sliding block 33.

[0065] The working principle is as follows:

[0066] The adjusting driver 31 drives the gear piece 32 to rotate, and since the gear piece 32 is engaged with the straight rack 34, the relative movement between the gear piece 32 and the straight rack 34 occurs; moreover, since the gear piece 32 itself is fixed with the adjusting driver 31 and can only rotate, and the straight rack 34 is rotatably connected to the detection base plate 1 at one end and is limited by the limiting sliding block 33, therefore, the straight rack 34 can move up and down during the engagement process, thereby driving the detection base plate 1 to move; since the limiting sliding block is rotatably arranged, it will not interfere with the swing of the straight rack 34 during the up and down movement, ensuring that the detection base plate 1 can be stably and smoothly driven to move around the first rotation shaft 11, and the swing angle control of the detection base plate 1 is realized.

[0067] The design means drives the detection base plate 1 to move through the cooperation of the gear piece 32, the straight rack 34 and the limiting sliding block 33, which can easily realize the overturning of the detection base plate 1, and the angle adjustment is more diverse and accurate, and the precise multi-stage angle adjustment can be realized. Moreover, the gear and rack cooperation is used to adjust the angle, which has compact structure and is beneficial to save the overall occupied space.

[0068] Further, as shown in the figure, Figure 2 and Figure 3 The second side edge opposite to the first side edge on the detection base plate 1 is rotatably installed with a rack fixing block 13 through a second rotation shaft 12; one end of the straight rack 34 is fixedly connected with the rack fixing block 13, so as to realize the rotatable connection between the one end of the straight rack 34 and the detection base plate 1.

[0069] Further, as shown in the figure, Figure 2 ​As shown, the adjusting driver 31 is a servo motor capable of forward and reverse rotation, fixed on the platform frame through a motor mounting plate 35. The servo motor has high control accuracy and can better achieve angle adjustment. The servo motor in the present application is a servo motor with a reducer, which is not limited in particular.

[0071] The gear member 32 is sleeved on the gear connecting shaft 37, and the limiting sliding block 33 is sleeved on the sliding block connecting shaft 38; the output shaft of the adjusting driver 31 is connected to the gear connecting shaft 37 through a shaft coupling 311.

[0072] The gear connecting shaft 37 is provided to fix the gear member 32, which facilitates the coaxial connection and fixation of the gear member 32 and the adjusting driver 31, and also facilitates the setting when multiple gear members 32 are required.

[0073] The sliding block connecting shaft 38 is provided to connect and fix the limiting sliding block 33, making the rotation setting of the limiting sliding block 33 more convenient, and also facilitating the setting when multiple limiting sliding blocks 33 are required.

[0074] Further, the straight rack 34 is two, arranged in parallel; correspondingly, the gear member 32 is two, corresponding to the straight rack 34; the limiting sliding block 33 is two, corresponding to the straight rack 34. The double straight rack 34 design can exert more uniform force on the detection base plate 1 and more reliably drive the detection base plate 1 to move. According to actual needs, the number of straight racks 34 can be varied and designed, without limitation.

[0075] Further, as shown in Figure 4 The platform frame has a first support surface 221 and a second support surface 231; the second support surface 231 is higher than the first support surface 221 and is distributed in a stepped manner with the second support surface 231; the detection base plate 1 is rotatably installed on the second support surface 231 and its back surface can be attached to the second support surface 231 when it is in a horizontal state; the electric adjusting mechanism 3 is installed on the first support surface 221.

[0076] The first support surface 221 and the second support surface 231 are designed to have a stepped distribution, wherein the second support surface 231 can provide horizontal support for the detection base plate 1; and the gap space formed between the first support surface 221 and the second support surface 231 can provide a certain installation space for the electric adjusting mechanism 3, better enabling the electric adjusting mechanism 3 to be installed, and the overall structure being more compact.

[0077] Further, the bearing mounting plate 36 is mounted on the first support surface 221; the top surface of the bearing mounting plate 36 is flush with the second support surface 231; the top surface of the bearing mounting plate 36 can be attached to the back surface of the detection base plate 1 in a horizontal state. With this design, the bearing mounting plate 36 can be used to increase the support effect on the detection base plate 1, making the horizontal state of the detection base plate 1 more reliable and stable.

[0078] Further, as shown in Figure 4 , in terms of the specific structural design of the platform frame, it includes the support 21, the first support plate 22 and the second support plate 23.

[0079] The support 21 is in a stepped shape; the first support plate 22 is fixed on the support 21, and the top surface forms the first support surface 221; the second support plate 23 is fixed on the support 21, and the top surface forms the second support surface 231; a plurality of hollow grooves 24 are provided on the first support plate 22 and the second support plate 23; the hollow grooves 24 can reduce the weight, making the overall transportation of the equipment more convenient, and saving certain material cost.

[0080] Further, as shown in Figure 5 , the limiting mechanism 4 includes a lower stop bar 41; the lower stop bar 41 is arranged on the top surface of the detection base plate 1 near the first rotating shaft 11, and can be in contact with the lower edge of the to-be-detected plate 5. The lower stop bar 41 can prevent the detection base plate 1 from sliding downward when it is in an inclined state, so that the to-be-detected plate 5 placed thereon does not slide downward. Of course, in order to improve the limiting effect, two side stop bars 42 can also be added to limit the displacement of the two sides of the to-be-detected plate 5. In this application, detection lamps 6 (LED lamps) are also arranged around the to-be-detected plate 5, and the specific arrangement is a known means, which will not be described here.
