Description

Technical Field

[0001] The present invention relates to the technical field of silica gel key detection, and in particular to silica gel key dust removal detection equipment and a method thereof. Background Art

[0002] As the name suggests, silicone keys are key products made of silicone as raw material. Silicone keys are a product category of silicone products. Silicone keys have excellent heat resistance, cold resistance, environmental resistance, electrical insulation, fatigue resistance and other characteristics.

[0003] In the production of silicone keys, it is necessary to spray corresponding key marks on the surface of some silicone keys.

A connecting block is fixedly connected between the movable block and the slider located in the front, and a second motor that drives the second threaded rod to rotate is fixedly installed at the left end of the device plate.

[0011] In the above-mentioned silicone key dust removal detection device and method, the component includes an electric track fixedly installed above two device plates and arranged longitudinally, and a track trolley slides on the electric track.

[0015] A detection method for a silica gel keypad dust removal detection device, the steps are as follows:

[0016] S1, the button positioning mechanism is moved to the bottom of the conveyor belt by the second motor, and the positioning box is rotated upward by the first motor so that the rear end opening thereof is rotated to be close to the front end of the conveyor belt, and the electric baffle is kept in a vertical blocking state;

[0017] S2. The rectangular silicone key to be tested is conveyed forward by the conveyor belt, so that the silicone key is conveyed into the positioning box in sequence. After the specified number of silicone keys are installed in the positioning box, the conveyor belt stops conveying, and the positioning box is rotated to a horizontal state again by the first motor, and then the double-headed motor is started. The double-headed motor can drive the two push plates to move closer together through the two first threaded rods, so that the push plates can push the corresponding end plates through the movable block, so that the two positioning plates in the positioning box can also move relatively, and push the rectangular silicone keys between the two. During the pushing process, under the limiting action of the two moving rods and the serpentine corrugated groove, the two positioning plates can move back and forth with the moving rod in a small range during the movement. In this state, the rectangular silicone key located in the positioning box and in contact with the positioning plate can be moved, so that each silicone key can smoothly make its own plane collide with the positioning plate, thereby completing a stable clamping work and avoiding the situation where the edges and corners collide with the positioning plate and thus cause extrusion and deformation;

[0018] S3. After completing the positioning and clamping of the silicone key, the positioning box is transported to the bottom of the dust removal mechanism, the key positioning mechanism releases the clamping of the silicone key, and the dust removal box moves to each silicone key in turn through the cooperation of the infrared identifier and the moving component, and the first suction head is made to be close to the upper end of the corresponding silicone key below through the first electric telescopic rod, and the silicone key is moved into the dust removal box, so as to use the suction force generated by the vacuum cleaner through the four second air pipes to clean the dust on the surface of the silicone key. After cleaning a silicone key, the cleaned silicone keys are arranged in the positioning box in equal intervals in turn by using the moving component, and then the arranged silicone keys are positioned and clamped by the key positioning mechanism;

[0019] S4. After the silicone keys are dusted and arranged equidistantly, the positioning box is transported to the bottom of the detection mechanism. The mobile component drives the industrial camera to mark and detect the silicone keys that are arranged equidistantly and positioned in a standardized manner in turn, and the position information of the silicone keys that do not meet the standards is transmitted to the computer device.

[0020] S5. After the inspection of the silicone key is completed, the positioning box is transported to the bottom of the screening mechanism, the positioning of the key positioning mechanism is released, and the computer device controls the screening mechanism and the moving component through the received information to move the second adsorption head to the top of the silicone key that does not meet the standards, and uses the suction force generated by the negative pressure pump to move the silicone key out of the positioning box;

[0021] S6. After the silicone buttons are screened out, the positioning box is transported to the rightmost end of the device plate. At this time, the electric baffle is rotated to a horizontal state, and the first motor controls the positioning box to rotate upward again to tilt the positioning box. At this time, the silicone buttons that are located in the positioning box and meet the detection standards slide out through the front end of the positioning box to complete automatic collection.

[0022] Compared with the existing technology, the advantages of this silica gel keypad dust removal detection device and method are:

[0023] By setting up a button positioning mechanism, the rectangular silicone button to be detected can be automatically placed in the positioning box and accurately clamped. The two positioning plates can move slightly back and forth with the moving rod during the movement. In this state, the rectangular silicone button located in the positioning box and in contact with the positioning plate can be moved, so that each silicone button can smoothly make its own plane collide with the positioning plate, thereby completing a stable clamping work and avoiding the situation where the edges and corners collide with the positioning plate and thus are squeezed and deformed.

[0024] By setting up a dust removal mechanism, the silicone buttons to be tested can be automatically dusted to ensure the effectiveness of the test.

[0025] By setting up a screening mechanism, unqualified keys can be automatically screened out, and the collection of unqualified keys and qualified keys can be automatically completed. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A detection method for a silica gel keypad dust removal detection device, the steps are as follows:

[0044] S1, the button positioning mechanism is moved to the bottom of the conveyor belt 10 by the second motor 29, and the positioning box 4 is rotated upward by the first motor 6, so that the rear end opening thereof is rotated to be close to the front end of the conveyor belt 10, and the electric baffle 11 is kept in a vertical blocking state;

In this state, the rectangular silicone buttons located in the positioning box 4 and in contact with the positioning plates 13 can be moved, so that each silicone button can smoothly make its own plane abut against the positioning plates 13, thereby completing a stable clamping work and avoiding the situation where the edges and corners abut against the positioning plates 13 and thus extrusion and deformation occur;

[0046] S3. After completing the positioning and clamping of the silicone key, the positioning box 4 is transported to the bottom of the dust removal mechanism, and the key positioning mechanism releases the clamping of the silicone key. The dust removal box 33 moves to each silicone key in turn through the cooperation of the infrared identifier and the moving component, and the first adsorption head 35 is made to be close to the upper end of the corresponding silicone key below through the first electric telescopic rod 34, and the silicone key is moved into the dust removal box 33, so that the dust on the surface of the silicone key is cleaned by the suction force generated by the vacuum cleaner 44 through the four second air pipes 37. After cleaning a silicone key, the cleaned silicone keys are arranged in the positioning box 4 in turn with equal distances by using the moving component, and then the arranged silicone keys are positioned and clamped by the key positioning mechanism;

[0047] S4. After the dust removal and equidistant arrangement of the silicone keys are completed, the positioning box 4 is transported to the bottom of the detection mechanism, and the mobile component drives the industrial camera 39 to mark and detect the silicone keys that are equidistantly arranged and properly positioned in turn, and the position information of the silicone keys that do not meet the standards is transmitted to the computer device;

[0048] S5. After the inspection of the silicone key is completed, the positioning box 4 is transported to the bottom of the screening mechanism, the positioning of the key positioning mechanism is released, and the computer device controls the screening mechanism and the moving component through the received information to move the second adsorption head 43 to the top of the silicone key that does not meet the standards, and uses the suction force generated by the negative pressure pump 42 to move the silicone key out of the positioning box 4;

[0049] S6. After the silicone buttons are screened out, the positioning box 4 is transported to the rightmost end of the device plate 1. At this time, the electric baffle 11 is rotated to a horizontal state, and the first motor 6 controls the positioning box 4 to rotate upward again, so that the positioning box 4 is tilted.

A detection method for a silica gel keypad dust removal detection device according to any one of claims 1 to 8, It is characterized in that Here are the steps: S1, the button positioning mechanism is moved to below the conveyor belt (10) by the second motor (29), and the positioning box (4) is rotated upward by the first motor (6), so that the rear end opening thereof is rotated to be close to the front end of the conveyor belt (10), and the electric baffle (11) is kept in a vertical blocking state; S2, the rectangular silicone key to be tested is conveyed forward by the conveyor belt (10), so that the silicone key is conveyed into the positioning box (4) in sequence. After the positioning box (4) is filled with a specified number of silicone keys, the conveyor belt (10) stops conveying, the positioning box (4) is rotated to a horizontal state again by the first motor (6), and then the double-headed motor (17) is started. The double-headed motor (17) can drive the two push plates (21) to move closer to each other through the two first threaded rods (18), so that the push plates (21) can push the corresponding end plates (15) through the movable block (20), so that the two positioning keys in the positioning box (4) are moved closer to each other. The plates (13) also move relatively to push the rectangular silicone keys located between the two. During the pushing process, under the limiting action of the two moving rods (24) and the serpentine corrugated grooves (22), the two positioning plates (13) can move forward and backward with the moving rods (24) in a small range during the moving process. In this state, the rectangular silicone keys located in the positioning box (4) and in contact with the positioning plates (13) can be moved, so that each silicone key can smoothly make its own plane abut against the positioning plate (13), thereby completing a stable clamping work and avoiding the situation where the edges and corners abut against the positioning plate (13) and thus extrusion deformation occurs; S3. After the positioning and clamping of the silicone key is completed, the positioning box (4) is transported to the bottom of the dust removal mechanism, the key positioning mechanism releases the clamping of the silicone key, and the dust removal box (33) is moved to each silicone key in turn through the cooperation of the infrared identifier and the moving component, and the first suction head (35) is made to be close to the upper end of the corresponding silicone key below through the first electric telescopic rod (34), and the silicone key is moved into the dust removal box (33), so that the dust on the surface of the silicone key is cleaned by the suction force generated by the vacuum cleaner (44) through the four second air pipes (37). After cleaning a silicone key, the cleaned silicone keys are arranged in the positioning box (4) in an equidistant manner in turn by using the moving component, and then the arranged silicone keys are positioned and clamped by the key positioning mechanism; S4. After the dust removal and equidistant arrangement of the silicone keys are completed, the positioning box (4) is transported to the bottom of the detection mechanism, and the mobile component drives the industrial camera (39) to mark and detect the silicone keys that are equidistantly arranged and positioned in a standardized manner in turn, and the position information of the silicone keys that do not meet the standards is transmitted to the computer device; S5. After the inspection of the silicone keys is completed, the positioning box (4) is transported to the bottom of the screening mechanism, the positioning of the key positioning mechanism is released, and the computer device controls the screening mechanism and the moving component through the received information to move the second adsorption head (43) to the top of the silicone keys that do not meet the standards, and uses the suction force generated by the negative pressure pump (42) to move the silicone keys out of the positioning box (4); S6. After the silicone keys are screened out, the positioning box (4) is transported to the rightmost end of the device plate (1). At this time, the electric baffle (11) is rotated to a horizontal state, and the first motor (6) controls the positioning box (4) to rotate upward again, so that the positioning box (4) is tilted. At this time, the silicone keys located in the positioning box (4) and detected to meet the standards slide out through the front end of the positioning box (4), completing the automatic collection.
