[0003] Chinese invention patent CN106453771A discloses a detection device for detecting mobile phone screens and shells. It includes a bottom plate and a support base, the bottom plate is surrounded by protective plates, a lifting frame and a ruler are installed on the support base, two adjustment plates are installed on the lifting frame, the adjustment plates are installed on the lifting frame through locking pieces, the locking pieces are loosened to adjust the adjustment plates to move horizontally along the lifting frame, and clamping mechanisms are installed on the adjustment plates.

[0004] However, during the hardness test of mobile phone screens, the device uses a steel ball to drop and hit the mobile phone screen. When testing multiple mobile phones in actual operation, it is necessary to manually bring the steel ball back to its initial height position, which is time-consuming and labor-intensive, and the operation is not convenient enough.

[0005] Therefore, it is necessary to provide a mobile phone screen performance detection device to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a mobile phone screen performance detection device to solve the existing problems in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a mobile phone screen performance detection device, comprising a rotating seat (29) and a guide cylinder (16) arranged on the top of the rotating seat (29), wherein a test ball (26) capable of falling freely is arranged inside the guide cylinder (16) to test the mobile phone on the side of the rotating seat (29);

[0008] A transverse axis (30) is arranged outside the guide cylinder (16). When the guide cylinder (16) rotates from 0° to 90°, the extrusion pressure of the transverse axis (30) on the test ball (26) gradually increases, thereby fixing the test ball (26) inside the guide cylinder (16). When the guide cylinder (16) rotates from 90° to 180°, the extrusion pressure of the transverse axis (30) on the test ball (26) gradually decreases. After the guide cylinder (16) rotates 180° and returns to a vertical state, the test ball (26) falls downward and lands on a mobile phone screen on the side of the rotating seat (29).

[0009] In specific use, when the sleeve (36) rotates 90 degrees, the distance moved by the horizontal axis (30) in the direction of the guide cylinder (16) is the largest, and at this time, the pressure on the connecting block (37) is also greater, which is conducive to pressing the connecting block (37) tightly inside the guide cylinder (16), thereby fixing the test ball (26) inside the guide cylinder (16). When the guide cylinder (16) rotates 90 degrees and then rotates to 180 degrees, the reciprocating screw (32) moves in a direction away from the guide cylinder (16), so that the pressure of the horizontal axis (30) on the connecting block (37) is further increased. The force gradually decreases, and when the guide cylinder (16) rotates 180 degrees and is in a vertical state again, the test ball (26) inside the guide cylinder (16) moves downward under the action of the external force and gradually breaks away from the contact with the horizontal axis (30), and finally falls freely under the action of gravity and falls on the collection screen to test the mobile phone screen. This device is configured by setting the guide cylinder (16). When the test ball (26) falls to the bottom, the guide cylinder (16) is flipped, and the test ball (26) can fall again for testing, with fast response time, sensitive and convenient operation, and high efficiency.

[0011] When in use, the cross-sectional shape of the limiting rod (19) is set to be L-shaped, which is beneficial for limiting the position of the mobile phone and preventing the mobile phone from falling off during the rotation process.

[0012] As a further solution of the present invention, the limiting rod (19) and the rotating seat (29) are both fixedly connected with a spring seat (23), a second spring (27) is arranged between the two spring seats (23), and one end of the limiting rod (19) is arranged as an arc segment.

[0013] When in use, one end of the limit rod (19) is arranged as an arc section, which is conducive to the mobile phone entering between the two limit rods (19). The mobile phone can be clamped by the second spring (27) outside the limit rod (19), which is conducive to the subsequent testing of its screen.

[0014] As a further solution of the present invention, the number of the test balls (26) is set to two, and the two test balls (26) are connected by a connecting block (37), and the connecting block (37) is slidably connected to the inside of the guide cylinder (16).

[0015] When in use, the test balls (26) are connected via the connecting blocks (37), which is beneficial for the transverse axis (30) to press the test balls (26) tightly.

[0017] When in use, the driving gear (4) can drive the driven gear (5) to rotate, and the driven gear (5) can drive the rotating shaft (7) to rotate through the driven belt (6), thereby driving the disc (8) to rotate, and a support is fixedly connected between the disc (8) and the guide cylinder (16), so that the disc (8) can drive the guide cylinder (16) to rotate.

[0018] As a further solution of the present invention, a motor (3) is arranged on the rear side of the rotating seat (29), the output end of the motor (3) is fixedly connected to a transmission shaft, a driven shaft is arranged on the top of the transmission shaft, the driven shaft and the outer sides of the transmission shaft are fixedly connected to a third pulley, a driven belt (6) is sleeved between the first pulley and the third pulley, a driving belt (2) is sleeved on the outer sides of the second pulley and the third pulley, a driving gear (4) is also fixedly connected to the outer side of the transmission shaft, a driven gear (5) is fixedly connected to the outer side of the driven shaft, and the driven gear (5) is meshed with the driving gear (4).

[0019] When in use, the output end of the motor (3) drives the transmission shaft to rotate, and the transmission shaft can drive the driving belt (2) to rotate, and then the driving belt (2) drives the support shaft (1) to rotate, and then the rotating seat (29) can be driven to rotate. At the same time, the transmission shaft can drive the driving gear (4) to rotate, and the driving gear (4) can drive the driven gear (5) to rotate. The driven gear (5) can drive the rotating shaft (7) to rotate through the driven belt (6), and then drive the disc (8) to rotate. A support is fixedly connected between the disc (8) and the guide cylinder (16), so that the disc (8) can drive the guide cylinder (16) to rotate. Here, the driving gear (4) drives the driven gear (5) to rotate relatively, thereby driving the guide cylinder (16) and the rotating seat (29) to rotate relatively. This structure is conducive to avoiding interference between the rotating seat (29) and the guide cylinder (16) during the rotation process, thereby ensuring the normal rotation of the guide cylinder (16) and the rotating seat (29).

[0020] As a further solution of the present invention, the transverse axis (30) is composed of a smooth rod (33) and a reciprocating screw (32), the reciprocating screw (32) is arranged at one end of the smooth rod (33) close to the guide cylinder (16), the guide cylinder (16) is fixedly provided with a ball nut pair (31) matched with the reciprocating screw (32), the smooth rod (33) is provided with a strip groove (34), the outer side of the smooth rod (33) is sleeved with a sleeve (36), the inner wall of the sleeve (36) is fixedly provided with a strip block (35) matched with the strip groove, one end of the reciprocating screw (32) passes through the guide cylinder (16) and extends to one side of the connecting block (37), the guide cylinder (16) is provided with a gear ring (17) on one side close to the transverse axis (30), and the outer side of the sleeve (36) is provided with a transmission tooth (24) meshing with the gear ring (17).

[0021] When used specifically, when the guide cylinder (16) rotates, the sleeve (36) on one side thereof can be driven to rotate, and the sleeve (36) can be driven to rotate by the engagement of the transmission teeth (24) on the outer side of the sleeve (36) with the gear ring (17), and the strip block (35) on the inner wall of the sleeve (36) and the strip groove (34) on the light rod (33) can be driven to rotate, thereby driving the reciprocating screw rod (32) to rotate, and the reciprocating screw rod (32) can be driven to move along its axial direction by the ball nut pair (31) on one side of the guide cylinder (16). When the sleeve (36) rotates 90 degrees, the distance moved by the transverse axis (30) in the direction of the guide cylinder (16) is the maximum, and at this time, the connection The greater the pressure of the block (37), the more favorable it is to press the connecting block (37) against the inside of the guide cylinder (16), thereby fixing the test ball (26) inside the guide cylinder (16). When the guide cylinder (16) rotates 90° and then rotates to 180°, the reciprocating screw (32) moves in a direction away from the guide cylinder (16), thereby gradually reducing the pressure of the horizontal axis (30) on the connecting block (37). When the guide cylinder (16) rotates 180° and is in a vertical state again, the test ball (26) inside the guide cylinder (16) moves downward under the action of external force and gradually breaks away from the contact with the horizontal axis (30), and finally falls freely under the action of gravity and falls onto the collection screen to test the mobile phone screen.

[0023] In specific use, when the driven gear (5) drives the guide cylinder (16) to rotate 180 degrees, the driving gear (4) only drives the rotating seat (29) to rotate 90 degrees. In actual operation, the guide cylinder (16) and the rotating seat (29) are driven to rotate simultaneously by the motor (3). After the guide cylinder (16) rotates 180 degrees, the motor (3) stops running. In the process of the guide cylinder (16) rotating from 0 degrees to 180 degrees, the squeezing force of the horizontal axis (30) on the connecting block (37) gradually increases to a maximum and then gradually decreases. When the guide cylinder (16) is in a vertical state, the repulsive force of the first magnet (12) on the second magnet (38) can promote the test ball (26) to fall. When the guide cylinder (16) rotates After 180°, the rotating seat (29) rotates exactly 90°, and the falling test ball (26) just tests the mobile phone that rotates to the bottom of the guide cylinder (16). The mobile phones on the side can be tested one by one by continuously rotating the rotating seat (29), and the cooperation of the guide cylinder (16) and the rotating seat (29) can improve the efficiency of the test. The traditional testing equipment needs to take the test ball (26) to the test position again after the test ball (26) falls, while this device uses the setting of the guide cylinder (16) to turn over the guide cylinder (16) after the test ball (26) falls to the bottom, and the test ball (26) can fall again for testing. The reaction time is fast, the operation is sensitive and convenient, and the efficiency is high.

[0024] In a mobile phone screen performance detection device described in the present invention, when the sleeve (36) rotates 90 degrees, the distance moved by the horizontal axis (30) in the direction of the guide cylinder (16) is the largest, and at this time, the pressure on the connecting block (37) is also greater, which is conducive to pressing the connecting block (37) inside the guide cylinder (16), thereby fixing the test ball (26) inside the guide cylinder (16), and when the guide cylinder (16) rotates 90 degrees and rotates to 180 degrees, the reciprocating screw (32) moves in a direction away from the guide cylinder (16), so that the horizontal axis (30) presses the connecting block The pressure of (37) gradually decreases. When the guide cylinder (16) rotates 180° and is in a vertical state again, the test ball (26) inside the guide cylinder (16) moves downward under the action of external force and gradually breaks away from the contact with the horizontal axis (30). Finally, it falls freely under the action of gravity and falls onto the collection screen to test the mobile phone screen. This device is configured by setting the guide cylinder (16). When the test ball (26) falls to the bottom, the guide cylinder (16) is flipped. At this time, the test ball (26) can fall again for testing. The reaction time is fast, the operation is sensitive and convenient, and the efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Furthermore, in order to complete automatic loading during the process of testing mobile phones, a material barrel (21) is arranged at one end of the rotating seat (29), and mobile phones are stacked inside the material barrel (21).

[0039] When in use, when the rotating seat (29) is in a horizontal state, its side surface is in the same horizontal plane as the top opening of the material barrel (21).

[0041] Furthermore, in order to fix the test ball (26) during the rotation of the guide cylinder (16), a transverse axis (30) is arranged on one side of the guide cylinder (16) close to the first electric push rod (20), and the transverse axis (30) is composed of a polished rod (33) and a reciprocating screw rod (32). The reciprocating screw rod (32) is arranged at one end of the polished rod (33) close to the guide cylinder (16), and a ball nut pair (31) matched with the reciprocating screw rod (32) is fixedly arranged on the guide cylinder (16), and a strip groove (34) is arranged on the polished rod (33), and the polished rod (33) is fixedly arranged on the guide cylinder (16). ) is sleeved on the outside, and a strip block (35) matching the strip groove is fixedly arranged on the inner wall of the sleeve (36). The strip block (35) is slidably connected to the inside of the strip groove (34), so that the rotation of the sleeve (36) can drive the horizontal shaft (30) to rotate, and one end of the reciprocating screw rod (32) passes through the guide cylinder (16) and extends to one side of the connecting block (37). A gear ring (17) is arranged on the side of the guide cylinder (16) close to the horizontal shaft (30), and a transmission tooth (24) meshing with the gear ring (17) is arranged on the outside of the sleeve (36).

[0042] In order to install the rotating seat (29), a first bracket (9) is provided on one side thereof, and a second bracket is provided on the other side thereof. The support shaft (1) passes through the first bracket (9) and the second bracket and is rotatably connected to the first bracket (9) and the second bracket, so as to support the rotating seat (29) to rotate stably. The first bracket (9) is provided with a circular hole matched with the disc (8), so that the disc (8) is rotatably connected to the first bracket (9). A fixing rod (18) is fixedly connected to the side of the gear ring (17) close to the first bracket (9). A fixing plate is fixedly connected to the first bracket (9). The fixing rod (18) is fixed to the fixing plate to install and fix the gear ring (17).

[0043] When in use, the output end of the motor (3) drives the transmission shaft to rotate, and the transmission shaft can drive the driving belt (2) to rotate, and then the driving belt (2) drives the support shaft (1) to rotate, which can drive the rotating seat (29) to rotate, and at the same time, the transmission shaft can drive the driving gear (4) to rotate, and the driving gear (4) can drive the driven gear (5) to rotate, and the driven gear (5) can drive the rotating shaft (7) to rotate through the driven belt (6), and then drive the disc (8) to rotate, and a support is fixedly connected between the disc (8) and the guide cylinder (16), so that the disc (8) can drive the guide cylinder (16) to rotate, The driving gear (4) drives the driven gear (5) to rotate relatively, thereby driving the guide cylinder (16) and the rotating seat (29) to rotate relatively. This structure is conducive to avoiding interference between the rotating seat (29) and the guide cylinder (16) during the rotation process, thereby ensuring the normal rotation of the guide cylinder (16) and the rotating seat (29). In the initial state, the guide cylinder (16) is in a vertical state, and the test ball (26) is placed at the bottom of the sleeve (36). When the guide cylinder (16) rotates, it can drive the sleeve (36) on one side to rotate, and the transmission teeth (24) on the outside of the sleeve (36) mesh with the gear ring (17). The movable sleeve (36) rotates, and the strip block (35) on the inner wall of the sleeve (36) cooperates with the strip groove (34) on the light rod (33) to drive the light rod (33) to rotate, thereby driving the reciprocating screw rod (32) to rotate, and the reciprocating screw rod (32) cooperates with the ball nut pair (31) on one side of the guide cylinder (16) to promote the horizontal axis (30) to move along its axial direction. When the sleeve (36) rotates 90 degrees, the distance moved by the horizontal axis (30) in the direction of the guide cylinder (16) is the largest. At this time, the pressure on the connecting block (37) is also greater, which is conducive to pressing the connecting block (37) tightly against the guide cylinder (16). ), and then fix the test ball (26) inside the guide cylinder (16). When the guide cylinder (16) rotates 90° and then rotates to 180°, the reciprocating screw (32) moves in a direction away from the guide cylinder (16), so that the pressure of the horizontal axis (30) on the connecting block (37) is gradually reduced. When the guide cylinder (16) rotates 180° and is in a vertical state again, the test ball (26) inside the guide cylinder (16) moves downward under the action of external force and gradually breaks away from the contact with the horizontal axis (30), and finally falls freely under the action of gravity and falls onto the collection screen to test the mobile phone screen.

[0044] In order to ensure that the test ball (26) can fall smoothly after the guide cylinder (16) rotates 180 degrees, a support frame (15) is fixedly connected to the top of the gear ring (17), and a slide plate (14) is arranged on the top of the guide cylinder (16). Notches are arranged on both the front and rear sides of the support frame (15), and both ends of the slide plate (14) pass through the notches. A guide rod (11) is fixedly connected inside the notch. The guide rod (11) passes through the slide plate (14) and is slidably connected to the slide plate (14). A first spring (10) is provided at both the top and the bottom. The first spring (10) is provided on the outside of the guide rod (11). A protrusion (25) extends from the top of the support frame (15) toward one side of the slide plate (14). A first magnet (12) is provided at the bottom of the protrusion (25) facing the through hole (13) on the slide plate (14). A second magnet (38) is provided on the side of the test ball (26) away from the connecting block (37). The first magnet (12) and the second magnet (38) repel each other.

[0045] When the guide cylinder (16) is in a vertical state after rotating 180 degrees, the test ball (26) will squeeze the slide plate (14), thereby driving the slide plate (14) to move upward, and the guide rod (11) is conducive to the stable movement of the slide plate (14), and the first spring (10) is conducive to the reset of the slide plate (14). When the guide cylinder (16) is in a vertical state, the test ball (26) is aligned with the through hole (13) on the slide plate (14). At this time, the repulsive force of the first magnet (12) on the second magnet (38) can drive the test ball (26) to move downward, thereby causing the connecting block (37) to gradually break away from the contact with the horizontal axis (30), and then fall downward under the action of its own gravity and fall onto the mobile phone screen, and then the guide cylinder (16) is continued to be driven to rotate by the motor (3). The mobile phone screen can be repeatedly tested by repeating the above process.

[0046] By providing a first pulley and a second pulley, during the actual installation process, the diameters of the first pulley and the third pulley are the same, while the diameter of the second pulley is twice the diameter of the first pulley, and the gear ratio of the driving gear (4) to the driven gear (5) is equal to one. In this way, when the driven gear (5) drives the guide cylinder (16) to rotate 180 degrees, the driving gear (4) only drives the rotating seat (29) to rotate 90 degrees. During the actual operation, the guide cylinder (16) and the rotating seat (29) are driven by the motor (3) to rotate simultaneously. After the guide cylinder (16) rotates 180 degrees, the motor (3) stops running. During the process of the guide cylinder (16) rotating from 0 degrees to 180 degrees, the squeezing force of the horizontal axis (30) on the connecting block (37) gradually increases to the maximum and then gradually decreases. When the guide cylinder (16) is in a vertical state, the first magnet (1 2) The repulsive force on the second magnet (38) can promote the test ball (26) to fall, and when the guide tube (16) rotates 180 degrees, the rotating seat (29) just rotates 90 degrees. At this time, the falling test ball (26) just tests the mobile phone rotated to the bottom of the guide tube (16). By continuously rotating the rotating seat (29), the mobile phones on its side can be tested one by one. The cooperation of the guide tube (16) and the rotating seat (29) can improve the test efficiency. The traditional test equipment needs to take the test ball (26) back to the test position after the test ball (26) falls. However, this device uses the setting of the guide tube (16). When the test ball (26) falls to the bottom, the guide tube (16) is flipped. At this time, the test ball (26) can fall again for testing. The reaction time is fast, the operation is sensitive and convenient, and the efficiency is high.

[0047] Afterwards, the telescopic end of the second electric push rod (22) drives the push plate to move so that the collected mobile phone that has been tested can be pushed out of the rotating seat (29), and the new mobile phone to be tested can be pushed to the bottom of the guide cylinder (16).

[0048] Working principle: The output end of the motor (3) drives the transmission shaft to rotate, and the transmission shaft can drive the driving belt (2) to rotate, and then the driving belt (2) drives the support shaft (1) to rotate, which can drive the rotating seat (29) to rotate, and at the same time, the transmission shaft can drive the driving gear (4) to rotate, and the driving gear (4) can drive the driven gear (5) to rotate, and the driven gear (5) can drive the rotating shaft (7) to rotate through the driven belt (6), and then drive the disc (8) to rotate, and a pillar is fixedly connected between the disc (8) and the guide cylinder (16), so that the disc (8) can drive the guide cylinder (16) to rotate, Here, the driving gear (4) drives the driven gear (5) to rotate relative to each other, thereby driving the guide cylinder (16) and the rotating seat (29) to rotate relative to each other. This structure is conducive to avoiding interference between the rotating seat (29) and the guide cylinder (16) during the rotation process, thereby ensuring the normal rotation of the guide cylinder (16) and the rotating seat (29). In the initial state, the guide cylinder (16) is in a vertical state, and the test ball (26) is placed at the bottom of the sleeve (36). When the guide cylinder (16) rotates, it can drive the sleeve (36) on one side thereof to rotate, and the transmission teeth (24) on the outside of the sleeve (36) mesh with the gear ring (17). The movable sleeve (36) rotates, and the strip block (35) on the inner wall of the sleeve (36) cooperates with the strip groove (34) on the light rod (33) to drive the light rod (33) to rotate, thereby driving the reciprocating screw rod (32) to rotate. The reciprocating screw rod (32) cooperates with the ball nut pair (31) on one side of the guide cylinder (16) to promote the horizontal axis (30) to move along its axial direction. When the sleeve (36) rotates 90 degrees, the distance moved by the horizontal axis (30) in the direction of the guide cylinder (16) is the largest. At this time, the pressure on the connecting block (37) is also greater, which is conducive to pressing the connecting block (37) against the guide cylinder (16). The test ball (26) is fixed inside the guide cylinder (16), and when the guide cylinder (16) rotates 90° and then rotates to 180°, the reciprocating screw (32) moves in a direction away from the guide cylinder (16), so that the pressure of the horizontal axis (30) on the connecting block (37) is gradually reduced. When the guide cylinder (16) rotates 180° and is in a vertical state again, the test ball (26) inside the guide cylinder (16) moves downward under the action of external force and gradually breaks away from the contact with the horizontal axis (30), and finally falls freely under the action of gravity and falls onto the collection mobile phone screen to test the mobile phone screen.
