Detailed implementation manners

[0019] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] As Figures 1 to 4 shown, a flatness automatic detection device, characterized in that it includes a workbench 1, a longitudinal guide rail 2 is provided on the upper side of the workbench 1, a fixture 3 is provided on the upper side of the longitudinal guide rail 2, the fixture 3 is provided with a positioning groove adapted to the shape of the product, a testing mechanism 4 and a press head mechanism 5 are provided on the upper side of the workbench 1, the testing mechanism 4 and the press head mechanism 5 are distributed along the direction of the longitudinal guide rail 2 on the upper side position of the longitudinal guide rail 2, and the testing mechanism 4 is used to detect the flatness of the device.

[0023] Combining the indenter mechanism 5 and the test results of flatness can detect the flatness of the device before and after pressing, so as to judge whether the device is pressed to meet the requirements during the pressing process, and then complete the pressing of the device and the flatness detection requirements. At this time, by detecting the flatness of the device to judge whether the pressing is in place, the installation quality of the device can be improved, thereby reducing the overall defective rate of the product and improving production efficiency.

[0024] At this time, the remote control product to be detected is placed at the position of the fixture 3 on the upper side of the longitudinal guide rail 2, while the test mechanism 4 and the indenter mechanism 5 are located on the upper side of the fixture 3. Specifically, in this embodiment, a transverse bracket 11 is provided on the upper side of the workbench 1 through a bracket. The transverse bracket 11 is located on the upper side of the longitudinal guide rail 2 and is perpendicular to the guiding rail. Further, the test mechanism 4 is arranged on one side of the transverse bracket 11, and the indenter mechanism 5 is arranged on the other side of the transverse bracket 11. Under the action of the transverse bracket 11, the test mechanism 4 and the indenter mechanism 5 can be arranged on the upper side of the longitudinal guide rail 2, so as to realize the flatness detection of the device at the position of the fixture 3 and the pressing process.

[0025] Regarding the test results, in this embodiment, the test mechanism 4 includes a linear motor 41 fixed to the side of the transverse bracket 11. A transverse moving plate 42 is arranged outside the linear motor 41. The outside of the transverse moving plate 42 is connected with a vertical moving plate 43 through a vertical guide rail slider structure. A test motor 44 for controlling the up and down movement of the vertical moving plate 43 is arranged on the upper side of the transverse moving plate 42. A laser displacement sensor 45 and a PCB probe 46 are arranged outside the vertical moving plate 43. Under the action of the linear motor 41, the transverse moving plate 42 can move horizontally along the direction of the transverse bracket 11, so as to control the horizontal and transverse movement of the vertical moving plate 43. Under the action of the test motor 44, the vertical moving plate 43 can move vertically. Therefore, a vertical moving plate 43 that moves in the horizontal and vertical directions can be obtained, and further, the laser displacement sensor 45 and the PCB probe 46 fixed outside the vertical moving plate 43 can move horizontally and vertically, so as to complete the test process.

[0026] During the test process, after pressing by the pressing mechanism, first control the vertical moving plate 43 to move to the upper side of the product in the fixture 3, and then control the vertical moving plate 43 to move downward, so that the laser displacement sensor 45 tests a height value (such as the middle position) of the device on the product in the fixture 3 before pressing as a reference point. Then, the laser displacement sensor 45 tests multiple height values (such as 4) of the device on the product in the fixture 3. Then, by judging the difference between the reference point and the multiple height values, if the difference is within a preset interval (such as ±0.02 mm), it is judged that the installation of the product device is qualified, otherwise it is a defective product.

[0027] At this time, when the vertical moving plate 43 moves downward, the PCB probe 46 contacts the PCB board, thereby obtaining the information of the PCB board, determining the size that the device needs to be pressed, and classifying the remote control in the subsequent process.

[0028] The pressing head mechanism 5 is used to press the device onto the PCB board. In this embodiment, the pressing head mechanism 5 includes a pressing head fixing plate 51. The side of the pressing head fixing plate 51 is connected with a pressing head moving plate 52 through a vertical guide rail slider structure. A pressing head structure 53 is arranged outside the pressing head moving plate 52. A pressing head motor 54 is arranged on the upper side of the pressing head fixing plate 51. The shaft of the pressing head motor 54 is connected with a lead screw 55. A moving pair that moves up and down is arranged outside the lead screw 55. The moving pair is fixed to the pressing head moving plate 52, thereby controlling the up and down movement of the pressing head moving plate 52 and the pressing head structure 53.

[0029] After initially placing the remote control into the positioning groove of the fixture 3, the device to be installed is installed at the corresponding position of the PCB board, and then manually pressed. At this time, the pressing is pre-pressing, and then the pressing is performed through the pressing head mechanism 5. At this time, the pressing head mechanism 5 is integrally arranged at the other side position of the horizontal bracket 11. Under the action of the pressing head motor 54, the lead screw 55 is controlled to rotate, thereby controlling the up and down movement of the moving pair. The pressing head moving plate 52 fixed to the moving pair moves up and down, so that the entire pressing head structure 53 moves up and down, and the pressing of the device is realized through the pressing head structure 53.

[0030] Specifically, the pressing head structure 53 includes a spring sleeve 531. The spring sleeve 531 includes a sleeve fixed to the lower side of the pressing head moving plate 52. An opening is arranged at the bottom of the sleeve. An elastic member is arranged inside the sleeve. A pressing rod 532 is arranged at the bottom of the sleeve. An adjustable pressing head 533 is arranged on the lower side of the pressing rod 532. A limiting sleeve is arranged outside the pressing rod 532. The limiting sleeve is fixed to the lower side of the sleeve. The pressing rod 532 passes through the limiting sleeve. When the pressing rod 532 moves downward, if the adjustable pressing head 533 on the lower side of the pressing rod 532 contacts the device to be pressed, the pressing rod 532 will compress the elastic member. In this way, the pressing rod 532 can form a buffer under the action of the elastic member during the downward movement, thereby avoiding the pressing rod 532 directly hitting the device and damaging the device and the PCB board.

[0031] Specifically, the adjustable pressure head 533 includes an upper pressure head 5331 fixed outside the pressure rod 532 in a sleeved manner. The side of the upper pressure head 5331 is fixed outside the pressure rod 532 through a fastener. The lower side of the upper pressure head 5331 is connected to a lower pressure head 5332 through a screw. A protruding pressure head portion 5333 is provided on the lower side of the lower pressure head 5332. Further, in order to ensure the levelness of the position of the pressure head portion 5333, fine adjustment of the pressure head portion 5333 is required. In this embodiment, the lower pressure head 5332 is further provided with a ball screw 5334. After passing through the lower pressure head 5332, the ball screw 5334 abuts against the lower side surface of the upper pressure head 5331. The ball screw 5334 and the screw are alternately distributed, so that the levelness of the position of the pressure head portion 5333 can be adjusted through the ball screw 5334, and further, after the pressure head portion 5333 presses the device, the device is prevented from tilting, thereby ensuring the connection quality between the device and the PCB board.

[0032] Since there are a pressing mechanism and a testing mechanism 4, and the two mechanisms are in different positions, during the production process, it is necessary to move the product to be tested on the fixture 3 between the two mechanisms. Therefore, in this embodiment, the flatness automatic detection device further includes a longitudinal motor for controlling the fixture 3 to move along the direction of the longitudinal guide rail 2. Under the action of the longitudinal motor, the fixture 3 moves along the direction of the longitudinal guide rail 2, so as to move under the pressing mechanism and under the testing mechanism 4, realize automatic movement to the position of the testing mechanism 4 after pressing, and complete the testing process, thereby improving the production testing efficiency.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0034] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
