DETAILED DESCRIPTION

[0021] Please refer to Figures 1-3 , the embodiment of the utility model is further explained;

[0022] As Figure 1 shown, the screw missing detection device includes machine table 1, the electric guide rail one 8 is installed above machine table 1, the movable seat 9 is slidably connected to the electric guide rail one 8, the electric guide rail two 10 is installed at the lower end of movable seat 9, and the installation plate 11 is fixed at the lower end of electric guide rail two 10; the discharge seat 6 is installed on the working surface of machine table 1, the feeding pipe 7 is fixed on the top of discharge seat 6 and communicates with discharge seat 6, and movable stations 5 are arranged on the both sides of discharge seat 6 and are installed on the working surface of machine table 1; the vacuum pump 12 is fixed on the installation plate 11, and the suction plate 13 is installed at the lower end of vacuum pump 12 and penetrates the bottom of installation plate 11;

[0023] In the scheme, when the battery cover panel is screwed, the two battery cover panels to be processed are placed on the two movable workstations 5 respectively. The movable workstations 5 are made of existing electric sliding rails and work panels. The work panels can be moved under the use of the electric sliding rails, so that the battery cover panel can be screwed in multiple places later. The external screws are transported into the discharge seat 6 through the feeding pipe 7. The discharge seat 6 is internally provided with an ejection mechanism (not shown). The screws are ejected from the discharge seat 6 in sequence through the ejection mechanism. Then the electric guide rail one 8 is started to drive the moving seat 9 to move horizontally. The moving seat 9 drives the mounting plate 11, the vacuum pump 12 and the suction plate 13 to move together. When the suction plate 13 moves above the screw, the electric guide rail one 8 is turned off. The electric guide rail two 10 is started to drive the mounting plate 11 to move downward. At the same time, the vacuum pump 12 is started to exhaust the air in the suction plate 13. After the suction plate 13 moves to the screw, the screw is sucked. Then the electric guide rail two 10 drives the mounting plate 11 to move upward. After that, the electric guide rail two 10 is turned off. The electric guide rail one 8 is started to drive the moving seat 9 to move, so that the screw is inserted into the screw hole of the battery cover panel. Then the electric guide rail two 10 drives the mounting plate 11 to move upward. The electric guide rail two 10 is turned off. The screws are tightened in the screw holes through the locking mechanism (not shown).

[0024] Holes one 14 and holes two 20 are horizontally distributed on the mounting plate 11. Transparent sheets 21 are installed in the holes two 20. Pressure testing components and a camera 22 for detecting missed screwing are installed on the mounting plate 11. The pressure testing components and the camera 22 correspond to the holes one 14 and the holes two 20 respectively.

[0025] The pressure testing components include an electric push rod 15, a pipe seat 16, a contact 17, a spring 18 and a pressure sensor 19. The electric push rod 15 is fixed on the mounting plate 11 through a support. The pipe seat 16 is fixed on the output end of the electric push rod 15. The pressure sensor 19 is fixed on the top of the inner wall of the pipe seat 16. The spring 18 is fixed on the bottom of the pressure sensor 19. The contact 17 is inserted into the bottom of the pipe seat 16 and is fixedly connected with the spring 18.

[0026] Yellow lights 3 and red lights 4 are installed in parallel on the machine table 1. A control panel 2 is installed on the machine table 1 and is electrically connected with the electric components in the device.

[0027] In the scheme, the pressure value of the pressure sensor 19 can be preset through the control panel 2. That is, when the screw is completely tightened in the screw hole of the battery cover panel, the contact 17 compresses the spring 18. The pressure applied to the pressure sensor 19 by the spring 18 is within the elastic range of the spring 18. The camera 22 shoots a photo of the screw completely tightened on the battery cover panel, which is used as a comparison photo for later comparison. The comparison photo is uploaded to the control panel 2. It should be noted that the machine table 1 should be placed on a horizontal table top to avoid affecting the detection results later.

[0028] The transparent sheet 21 is arranged to protect the camera 22 shooting end. After the battery cover panel is screwed, the control panel 2 is clicked to start the electric guide rail 8 to drive the moving seat 9 and the pressure test assembly to move horizontally. When the pressure test assembly moves above the screw hole of the battery cover panel, the control panel 2 starts the electric push rod 15 in the pressure test assembly, the electric push rod 15 drives the pipe base 16 and the contact 17 to move downward, the contact 17 moves into the screw hole of the battery cover panel after passing through the hole 14, if the screw is missed, the contact 17 cannot contact the object, the contact 17 is not forced, the pressure sensor 19 tests no result, then feedback to the control panel 2, the control panel 2 starts the red light 4 to prompt the staff that there is a missed screw on the battery cover panel;

[0029] If the screw is not installed tightly, the contact 17 will contact the screw earlier than the installed screw, the contact 17 is compressed after moving downward to compress the spring 18, the spring 18 gives the pressure sensor 19 an elastic force, at this time, the pressure measured by the pressure sensor 19 is greater than the preset value, the control panel 2 gets the data and also starts the yellow light 3 to prompt the staff that there is a screw not installed tightly on the battery cover panel;

[0030] If the screw is completely installed tightly, the data measured by the pressure sensor 19 is equal to the preset value, which means that the detection is qualified, the specific test operation of the pressure sensor 19 is consistent with the above, and will not be repeated, then the next operation is continued;

[0031] After the pressure test assembly test is completed, the electric push rod 15 drives the pipe base 16 and the contact 17 to move upward, the electric push rod 15 is turned off, the electric guide rail 8 is started to drive the moving seat 9 to move, so that the camera 22 moves above the screw hole of the battery cover panel, at this time, the control panel 2 starts the camera 22 to shoot the battery cover panel, then the photo is transmitted to the control panel 2, if the shot battery cover panel is consistent with the contrast, then the yellow light 3 and the red light 4 are not lit, which means that the detection is qualified; otherwise, it is unqualified.

[0032] Compared with the prior art, the advantages of the present application are:

[0033] 1. Under the use of the pressure test assembly, not only the missed screw on the battery cover panel can be detected, but also the screw not installed tightly on the battery cover panel can be detected; it is beneficial for the staff to timely handle the unqualified battery cover panel and timely check whether the equipment has a fault

[0034] 2. The camera 22 shoots the processed battery cover panel, the shot photo can be compared with the contrast for secondary detection, which is beneficial for the device to detect more accurately.
