DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 8, an automatic detection device for the size of a mobile phone middle frame, comprising two slides 1 and two parallel vertical plates 14; a slider 16 is slidably installed on the top of each of the two vertical plates 14, a slider 2 19 is arranged between the two vertical plates 14, and the slider 1 16 and the slider 2 19 are both configured to be able to reciprocate along the length direction of the vertical plates 14; a slide 1 is fixedly connected between the two sliders 16; at least two lifting columns 18 are arranged on the slider 2 19, the lifting columns 18 vertically penetrate and are slidably connected to the slider 2 19, and the tops of at least two lifting columns 18 are fixedly connected to another slide 1.

[0027] A track groove 15 is provided on each of the two vertical plates 14, and the track groove 15 is arranged along the length direction of the vertical plate 14, and the track groove 15 consists of a groove 1 151, a groove 2 152, a groove 3 153, a groove 4 154 and a groove 5 155 which are sequentially connected in the length direction of the vertical plate 14, the groove 151, the groove 3 153 and the groove 5 155 are all horizontally arranged, and the groove 2 152 and the groove 4 154 are distributed in a "V" shape; two lifting plates 17 are arranged between the two vertical plates 14, and the two lifting plates 17 are respectively slidably arranged in the two track grooves 15, and the two lifting plates 17 are connected and fixed to the slide 1 fixed on the lifting column 18.

[0028] By moving one slide 1 along a horizontal moving track parallel to the length direction of the vertical plate 14, and moving the other slide 1 along the track groove 15, and during the movement, the horizontal distance between the two slides 1 is reciprocatedly reduced and increased, and the vertical distance is reciprocatedly increased and reduced, so that the two slides 1 can switch between the loading station and the unloading station along their respective designated tracks, and the two slides 1 switch between the loading station and the unloading station alternately.

[0029] Each slide 1 is installed with an axis 2, which is a gear axis and is vertically distributed. The axis of the axis 2 passes through the slide 1 upward and is rotatably connected, and the tooth of the axis 2 is located below the slide 1. A mounting platform 3 is fixedly installed on the top of each axis 2, and the mounting platform 3 can rotate relative to the slide 1 through the axis 2. A carrier plate 5 for carrying the mobile phone middle frame 100 is rotatably installed on the top of each mounting platform 3 through the axis 2 4. Specifically, the axis 2 4 is connected to the fixed carrier plate 5, and the axis 2 4 is rotatably connected to the mounting platform 3, and an elastic member 11 is arranged between the axis 2 4 and the mounting platform 3. Through the axis 2 4, the carrier plate 5 can swing relative to the mounting platform 3 so that the carrier plate 5 can switch between the horizontal state and the vertical state; through the elastic member 11, the carrier plate 5 can be converted from the vertical state to the horizontal state. It should be noted that in this embodiment, the elastic member 11 can be selected as any one of a coil spring and a torsion spring, and the two ends of the elastic member 11 are respectively connected to the fixed axis 2 4 and the mounting platform 3. When the carrier plate 5 is transformed from a horizontal state to a vertical state, the elastic member 11 is elastically deformed; the elastic member 11 releases elastic potential energy to transform the carrier plate 5 from a vertical state to a horizontal state and abut against the upper surface of the mounting platform 3 .

[0030] The length of the loading plate 5 is smaller than that of the mobile phone middle frame 100 , so that a portion of the mobile phone middle frame 100 can be exposed from the loading plate 5 , making it convenient to remove the mobile phone middle frame 100 from the loading plate 5 .

[0031] At the loading station, the carrier plate 5 is in a horizontal state and abuts against the upper surface of the mounting table 3. The mobile phone middle frame 100 is placed on the carrier plate 5 in a horizontal state, and the length direction of the mobile phone middle frame 100 is perpendicular to the length direction of the vertical plate 14. The carrier plate 5 is a negative pressure suction plate, and a plurality of adsorption holes and positioning columns that are compatible with the mobile phone middle frame 100 are provided on the carrier plate 5. The mobile phone middle frame 100 is accurately positioned on the carrier plate 5 by the positioning columns, and the mobile phone middle frame 100 is fixed on the carrier plate 5 by forming a negative pressure between the carrier plate 5 and the mobile phone middle frame 100. At the unloading station, the carrier plate 5 and the mobile phone middle frame 100 are both in a vertical state, and part of the mobile phone middle frame 100 is exposed from the carrier plate 5, such as Figure 1 and Figure 2 When the mobile phone middle frame 100 is removed from the loading board 5 , the material taking mechanism for clamping the mobile phone middle frame 100 clamps the mobile phone middle frame 100 outside the loading board 5 , and then the loading board 5 is desorbed, and the material taking mechanism moves the mobile phone middle frame 100 horizontally away from the loading board 5 .

[0032] The elastic member 11 drives the carrier plate 5 to flip back to a horizontal state after the mobile phone middle frame 100 is away from the carrier plate 5 by at least a width of the mobile phone middle frame 100 .

[0033] Each slide 1 is equipped with a transmission member 16 and a transmission member 39. The transmission member 16 meshes with the teeth on the shaft 12, and the transmission member 16 meshes with the transmission member 27. The transmission member 27 is a linear rack, and the transmission member 27 is fixed on a vertical plate 14 and close to the unloading station. When the transmission member 16 moves with the slide 1 and meshes with the transmission member 27, the transmission member 16 will drive the shaft 12 to rotate around its own central axis, so that the mounting platform 3 is in a horizontal state.

[0034] like Figure 4 As shown, the slide 1 is a plate-like structure with a protrusion in the middle, the toothed portion of the shaft 1 2 is located below the protrusion, and the mounting platform 3 is located above the protrusion; the transmission member 1 6 includes a gear 1 61, a gear 2 62 and a transmission rack 63, both of which are rotatably mounted on the upper surface of the slide 1 and located on the same side of the protrusion through the shaft, and the gear 2 62 is meshedly connected with the gear 1 61 and the transmission rack 63, and the transmission rack 63 horizontally penetrates the slide 1 and is meshedly connected with the toothed portion of the shaft 1 2, and the gear 1 61 can be meshedly connected with the transmission member 2 7. The number of teeth of the gear 1 61 is greater than the number of teeth of the gear 2 62.

[0035] The rotation of axis 2 that occurs when the slide 1 moves from the loading station to the unloading station is defined as forward rotation, and the rotation of axis 2 that occurs when the slide 1 moves from the unloading station to the loading station is defined as reverse rotation.

[0036] During the movement of the slide 1 from the loading station to the unloading station, as the gear 1 61 meshes with the transmission member 2 7, the gear 2 62 rotates to push the transmission rack 63 into the slide 1, and the drive shaft 1 2 rotates in the forward direction, causing the mounting platform 3 to rotate horizontally, and then causing the loading plate 5 and the mobile phone middle frame 100 to rotate horizontally, so that the angle between the length direction of the mobile phone middle frame 100 and the length direction of the vertical plate 14 in the horizontal plane changes from a right angle to an acute angle.

[0037] like Figure 5As shown, a transmission member 3 9 is fixed on a vertical surface of the slide 1 facing the unloading station, a transfer member 8 is installed on the shaft 1 2 , a laser scanner 2 13 is installed at the moving end of the transfer member 8 , and the transfer member 8 intermittently engages with the transmission member 3 9 . Specifically, the transmission member three 9 is composed of an arc-shaped rack and an arc bar, and the arc-shaped rack and the arc bar are arranged along the same arc line; the transfer member 8 includes a transfer frame 81, a transmission shaft 82, a screw rod 83 and a transfer seat 84, the transfer frame 81 is fixed on the surface of the shaft one 2 located between the slide 1 and the mounting table 3, the transfer frame 81 is located above the transmission member three 9, the transmission shaft 82 is a gear shaft and is vertically arranged, the tooth portion of the transmission shaft 82 can engage with the arc-shaped rack, the shaft portion of the transmission shaft 82 passes through and rotates to connect the transfer frame 81 upward, the screw rod 83 is horizontally arranged and one end of the screw rod 83 passes through and rotates to connect the transfer frame 81, the transmission shaft 82 and the screw rod 83 are connected together through a bevel gear transmission mechanism, the transfer seat 84 is threadedly sleeved on the surface of the screw rod 83 and the transfer seat 84 is slidably connected to the transfer frame 81, and the laser scanner two 13 is fixed on the transfer seat 84.

[0038] During the forward rotation of axis 2, the transfer frame 81 rotates with axis 2, causing the laser scanner 2 13 and the mobile phone middle frame 100 to rotate around the axial direction of axis 2 at the same time, and the transmission shaft 82 moves from the arc rack to the arc bar and drives the screw 83 to rotate when engaging with the arc rack, so that the transfer seat 84 and the laser scanner 2 13 both move along the length direction of the mobile phone middle frame 100, and the laser scanner 2 13 scans and measures the length of the mobile phone middle frame 100; after the transmission shaft 82 moves to the arc bar position, the screw 83 stops rotating, and the laser scanner 2 13 completes the measurement of the length of the mobile phone middle frame 100.

[0039] During the reverse rotation of shaft 1 2 , the transmission shaft 82 moves from the arc bar to the arc-shaped rack and drives the laser scanner 2 13 to move and reset when it engages with the arc-shaped rack.

[0040] like Figure 6 and Figure 7 As shown, a transmission plate 41 is fixed on the surface of shaft 2 4, and a transmission member 4 10 is fixedly connected to the slide 1. Shaft 2 4 is intermittently connected to the transmission member 4 10 through the transmission plate 41; specifically, during the forward rotation of shaft 1 2, when the transmission shaft 82 engages with the arc-shaped rack, the transmission plate 41 rotates toward the transmission member 4 10, and when the transmission shaft 82 moves along the arc, the transmission plate 41 moves along the upper surface of the transmission member 4 10 and drives shaft 2 4 to rotate, thereby converting the loading plate 5 from a horizontal state to a vertical state, and converting the mobile phone middle frame 100 from a horizontally placed detection state to a vertically placed unloading state.

[0041] During the reverse rotation of axis 1 2 , when the transmission shaft 82 moves along the arc, the elastic member 11 drives axis 2 4 to rotate and reset, converting the mobile phone middle frame 100 from a horizontally placed detection state to a vertically placed unloading state to a horizontal state and against the upper surface of the mounting table 3 .

[0042] Furthermore, the cross-sectional edge contour of the transmission plate 41 at one end away from the axis 2 4 is composed of a curve and a straight line, and the center of the curve is staggered with the center of the axis 2 4, the portion of the transmission plate 41 corresponding to the curve contour is the curve contour portion, and the portion of the transmission plate 41 corresponding to the straight line contour is the straight line contour portion; define the end of the curve connected to the straight line as the beginning of the curve, and the end of the straight line connected to the curve as the end of the straight line, then the other end of the curve is the end of the curve, and the other end of the straight line is the beginning of the straight line. Therefore, according to the above, the distance from the edge of the transmission plate 41 to the center of the axis 2 4 gradually increases from the beginning of the straight line to the end of the curve.

[0043] The transmission member 410 is an arc-shaped plate structure and is coaxially arranged with the shaft 12. The upper surface of the transmission member 410 is composed of a plane and a gradually rising inclined surface along the rotation direction of the shaft 12, and the highest position of the plane and the inclined surface are connected. During the positive rotation of the shaft 12, the curved contour portion on the transmission plate 41 rotates and moves upward along the upper surface of the transmission member 410 and rotates around the central axis of the shaft 24, thereby driving the shaft 24 to rotate around its own central axis, causing the elastic member 11 to deform elastically. When the straight line of the transmission plate 41 abuts against the upper surface of the transmission member 410, the shaft 24 rotates 90 degrees, so that the carrier plate 5 is in a vertical state.

[0044] In order to prevent the loading plate 5 from rotating further after rotating to the vertical position, when the loading plate 5 rotates to the vertical position, the straight contour portion on the transmission plate 41 contacts the plane on the transmission member 410, and the transmission plate 41 abuts against the limit block 20 fixed on the mounting table 3. Figure 8 shown.

[0045] It also includes two laser scanners 12 installed on the same vertical plate 14, and the laser scanners 12 are used to scan and measure the width of the mobile phone middle frame 100. The two laser scanners 12 are respectively matched with the two slides 1, and the two laser scanners 12 respectively measure the width of the corresponding mobile phone middle frame 100 when the two slides 1 move from the loading station to the unloading station.

[0046] The laser scanner 12 corresponding to the slide 1 moving along the track groove 15 can move in the direction opposite to the moving direction of the mobile phone middle frame 100 when scanning and measuring the width of the mobile phone middle frame 100. This movement is achieved by a linear drive (such as a cylinder, a linear motor module) installed on a vertical plate 14.

[0047] It should be noted that, in the present invention, the width of the mobile phone middle frame 100 is measured before the length of the mobile phone middle frame 100 is measured.

[0048] Through the above, the present invention, in the process of the slide 1 moving from the loading station to the unloading station, the width of the mobile phone middle frame 100 is measured by scanning with the laser scanner 12, and then, the transmission member 16 is engaged with the transmission member 27 to drive the shaft 2 to rotate around its own central axis, so that the transfer member 8 rotates around the shaft 12 and engages with the transmission member 3 9 during the rotation to drive the laser scanner 2 13 to move and measure the length of the mobile phone middle frame 100 and then disengage from the transmission member 3 9, and the shaft 2 4 is connected to the transmission member 4 10 after the transfer member 8 is disengaged from the transmission member 3 9, and the loading plate 5 is converted from a horizontal state to a vertical state, so that the mobile phone middle frame 100 is converted from a horizontally placed detection state to a vertically placed unloading state, to realize continuous detection of the width and length of the mobile phone middle frame 100, to realize continuous detection of the width and length of multiple mobile phone middle frames 100, to improve the detection efficiency, and to make the mobile phone middle frame 100 after the size detection is in a vertical state, which is convenient for unloading the mobile phone middle frame 100 after the detection.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
