DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0032] Embodiment 1, this embodiment aims to provide a communication equipment testing device, which is mainly used to detect the screen of the communication equipment. The improvement of this embodiment lies in the overall arrangement of press detection, line detection and tapping detection. In view of the fact that the existing integrated structure cannot take into account press, line and tapping detection, they are generally arranged separately and each item is tested separately. The detection items are not related to each other and are just simple additions of some functions. Moreover, this method is costly, occupies a large area, has many drive structures, and is not convenient for maintenance. In order to simplify the equipment, this embodiment provides a communication equipment testing device.

[0033] In this embodiment, the communication device can be described by taking a mobile phone as an example, but the implementation scope is not limited to this. The screen of the mobile phone is a planar structure, and this embodiment is described with respect to this structure.

[0034] like Figure 1-4 In the figure, a communication equipment test device is shown, including a rack 1, a transport mechanism, a pressing and knocking mechanism and a marking mechanism; wherein the transport mechanism is used to transport the communication equipment and operate in the form of an assembly line. The specific structure is as follows Figure 1 and Fig.11 As shown in the figure, the transport mechanism includes a synchronous conveyor belt 12, a sliding seat 15 and a fixed seat 18; wherein the synchronous conveyor belt 12 is arranged on both sides of the frame 1, and the two synchronous conveyor belts 12 are connected by a linkage shaft, and one synchronous conveyor belt is driven by a motor, and the other synchronous conveyor belt is driven to rotate by the linkage shaft to achieve the purpose of synchronization; in this embodiment, mounting seats 13 are arranged on both synchronous conveyor belts 12, and both ends of the support rod 14 are respectively fixed on the mounting seats 13 on both sides, so that as the synchronous conveyor belt 12 rotates, the support rod 14 can be driven to move synchronously.

[0035] Limit blocks 16 are arranged at intervals on the support rod 14, and the sliding seat 15 is mounted on the support rod 14 and is located between the two limit blocks 16. The support rod 14 between the limit blocks 16 is a square structure, which enables the sliding seat to slide along the support rod but will not flip over; at the same time, a temporary adsorption magnetic attraction structure is arranged between the sliding seat 15 and the limit blocks 16, which is not shown in the figure and can be arranged on the side of the docking surface of the two, with a magnet arranged on one of them and an iron block arranged on the other.

[0036] In this embodiment, the fixed seat 18 is fixed on the upper part of the sliding seat 15 and is used to fix the communication equipment. The specific fixing method can be clamping fixation or negative pressure adsorption fixation. A driving plate 17 is provided at the lower part of the sliding seat 15. In this embodiment, the sliding seat 15 has two stable states, namely, it is temporarily fixed with the limit seats 16 on both sides, and the two states correspond to the pressing station and the knocking station respectively.

[0037] like Fig.11 It is shown in the figure that in order to improve the structural stability at the pressing and tapping stations and prevent the synchronous conveyor belt from deforming after receiving external force, a moving wheel 25 is provided on the support rod 14 in this embodiment, and a supporting platform 26 is provided on the frame 1. When the support rod 14 enters the test station (pressing station, marking station and tapping station), the moving wheel 25 is on the supporting platform 26, that is, the moving wheel is located on the supporting platform at this time and can be supported from the bottom.

[0038] like Figure 1-5 As shown in FIG. 1 , the pressing and knocking mechanism includes a driving motor 2, a driving arm 3, a center seat 5, a knocking arm 9 and a pressing arm 6; the center seat 5 and the driving motor 3 are staggered and fixed on the frame 1, as shown in FIG. Figure 5 To assist in the display, the center seat 5 is on the lower right, and the driving motor 3 is on the upper left. The specific structure of the frame 1 can be set according to actual needs, and its purpose is to support and fix; the fixing method of the motor is relatively traditional and is not shown. This embodiment discloses a partial structure of the frame, which has at least two side panels arranged at intervals, and the synchronous conveyor belts 12 are respectively located in the two side panels, and drive the support rods 14 to move between the two side panels, and brackets 11 are arranged on both sides of the side panels to support the center seat 5.

[0039] In this embodiment, the inner ends of the knocking arm 9 and the pressing arm 5 are coaxially rotatably arranged on the center seat 5, and a sliding hole 8 is arranged on the pressing arm 6. One end of the driving arm 3 is transmission-connected to the rotating shaft of the driving motor 2, and the other end is provided with a slider 4. The slider 4 is matched and sleeved in the sliding hole 8 and can slide along the sliding hole 8. In the specific implementation, the sliding hole 8 is a T-shaped hole structure, and the slider 4 is matched and nested and restricted in the T-shaped hole. The slider 4 is a circular block structure, which is nested in the T-shaped hole, so that the pressing arm 6 can swing in a plane, and the structure is relatively stable.

[0040] A knocking head 10 and a pressing head 7 are respectively provided at the outer ends of the knocking arm 9 and the pressing arm 6, and when the knocking head 10 and the pressing head 7 swing downward to the extreme position, the knocking head 10 and the pressing head 7 are at the same level; when the knocking head 10 and the pressing head 7 swing downward to the extreme position, the knocking head and the pressing head are in vertical contact with the screen, and at the moment of pressing or knocking, the knocking head and the pressing head produce a certain deformation to generate the knocking and pressing action. The material and structure of the knocking head and the pressing head can be a rubber cone-shaped structure, which can buffer the force and avoid damage to the screen.

[0041] The marking mechanism includes a pneumatic head 19 and a marking head 20. The marking head 20 is fixed at the bottom of the center seat 5 and is between two limit blocks. The pneumatic head 19 is arranged on the frame and corresponds to the marking head. When the driving plate passes through the pneumatic head 19, the pneumatic head 19 sprays gas and blows the sliding seat 15 from one limit block 16 to another limit seat. During the sliding process, the screen of the communication equipment passes through the marking head 20. In order to determine the driving moment of the pneumatic head, a position sensor is provided on the center seat in this embodiment. The position sensor is used to obtain the position of the driving plate 17 and control the operation of the pneumatic head 19 through a controller. The pneumatic head is connected to the air pump and sprays high-intensity air pressure after being turned on. The high-intensity air pressure acts on the driving plate 17 and causes the sliding seat 15 to slide on the support rod.

[0042] At the same time, a monitoring mechanism is arranged on the central seat or the frame, and the monitoring mechanism includes a pressing monitoring camera, a line monitoring camera and a knocking monitoring camera. The pressing monitoring ray head 27, the line monitoring camera 28 and the knocking monitoring camera 29 are fixed on the central seat 5 or the frame, and can respectively collect images of the screen after pressing, the screen after drawing and the screen after knocking. Figure 7 As shown in FIG. 5 , this embodiment shows a method of arranging three types of surveillance cameras on the central seat 5 .

[0043] The working principle of this embodiment is as follows: this embodiment provides two spaced-apart center seats 5 and a driving motor 2, the rotating shaft of the driving motor 2 provides rotational power and drives the driving arm 3 to swing around the rotating shaft of the driving motor, a slider 4 is provided at the end of the driving arm 3, a sliding hole 8 is provided on the pressing arm 6, the slider 4 slides in the sliding hole 8, and the pressing arm 6 and the knocking arm 9 are coaxially arranged on the center seat, when the pressing arm swings, the knocking arm 9 is also driven to swing, and the swinging amplitudes of the two are the same, and the driving arm swings in a circle.

[0044] In this embodiment, a connecting shaft 24 is provided on the center seat 5, and the two ends of the connecting shaft 24 are respectively fixedly connected to one end of the pressing arm and the knocking arm. The pressing arm 6 and the knocking arm 9 are on the same horizontal line and swing around the connecting shaft 24 of the center seat. When the pressing arm 6 is in the highest position, the knocking arm is in the lowest position at the bottom, and vice versa. In this embodiment, the pressing arm and the knocking arm are respectively in two different planes.

[0045] like Fig. 9 In the figure, the driving arm swings counterclockwise. During one swing, its end will press the arm with two vertical points, namely vertical point A and vertical point B. When the driving arm and the pressing arm remain vertical at vertical point A, the pressing arm is swung downward to the maximum amplitude, while the striking arm is reversed to the upper limit position. At this time, the end of the driving arm is close to the connecting shaft on the center seat (the common rotation axis of the pressing arm and the striking arm), and the overall structure is in the pressing position. When it continues to pass vertical point A, it will proceed to vertical point B after a smaller rotation angle. This process takes a short time. At the B vertical point, the pressing arm is in an upward swing amplitude, and the knocking arm is in the lowest extreme position, that is, the driving arm swings from the A vertical point to the B vertical point, the knocking arm swings from the uppermost part to the lowermost part, and the pressing arm swings from the lowermost part to the uppermost part. In the process, the time from A to B is shorter, with a faster swing state, and the time from B to A is longer, with a slower swing speed. In this embodiment, the pressing state is applied from B to A, with a slower swing amplitude, and slow pressing is performed, while the knocking is applied from A to B, with a faster swing amplitude, and fast knocking is performed.

[0046] In terms of basic structure, the detection of three items can be achieved by adopting a driving motor that continuously rotates and a pneumatic head that moves in an inching manner. In specific implementation, the driving motor of the present invention drives the driving arm to continuously rotate, and a slider is provided at the end of the driving arm to keep the center seat away from the driving motor shaft. A connecting shaft is provided on the center seat, and a knocking arm and a pressing arm are provided at both ends of the connecting shaft, respectively. A sliding hole is provided on the pressing arm, and the slider is mounted in the sliding hole. The pressing arm is driven to swing under the rotation of the motor. The distance between the center seat and the motor shaft is designed so that the pressing arm can swing at a specific angle. At the same time, the pressing arm is used to drive the knocking arm to swing. During specific work, since the driving arm is close to the pressing arm and the knocking arm is far away from the driving arm, the pressing arm is on one side of the connecting shaft and the knocking arm is on the opposite side. When the pressing arm presses the screen downward, the pressing arm descends slowly, and when the knocking arm knocks the screen downward, the knocking arm descends quickly, thereby achieving the purpose of light pressing and fast knocking, and can truly simulate the situation of manual detection. In addition, the present invention can realize the knocking and pressing functions through one motor, has a novel and compact structure, and realizes the marking operation during the workstation switching process.

[0047] Embodiment 2: This embodiment further provides a structure for adjusting the intensity of knocking and pressing.

[0048] This embodiment also includes an adjustment mechanism, such as Figure 4 In the figure, the adjustment mechanism includes an adjustment block, an adjustment seat 21 and an adjustment rod 22. The bottom of the center seat 5 is provided with an adjustment block, and the adjustment seat 22 is provided with an adjustment groove. The adjustment block is matched and fitted in the adjustment groove and can slide along the adjustment groove. A bearing is provided on the side wall of the adjustment groove, and a threaded hole corresponding to the bearing is provided on the adjustment block. The adjustment rod 22 is threadedly connected in the threaded hole and is rotatably connected with the bearing. A driving wheel 23 is provided at the outer end of the adjustment rod 22. By rotating the adjustment rod, the adjustment block itself is restricted in the adjustment groove, and it will not rotate by itself, but can only slide along the adjustment groove following the threaded drive of the adjustment rod, so as to realize the adjustment of the distance between the center seat and the driving motor. Fig.10 It is shown in the figure that when the distance between the two increases, the knocking intensity increases, while the pressing intensity becomes weaker. Conversely, the knocking intensity decreases and the pressing intensity increases. This range is limited to a certain range.

[0049] In order to adapt to this structure, in this embodiment, a hinged seat is provided at the end of the pressing arm, and the pressing head is hinged on the hinged seat through a pin shaft and can be locked. The knocking arm is a telescopic rod structure, and the telescopic rod structure can include a sleeve rod, a sleeve and a top screw. The sleeve rod is sleeved in the sleeve and can be locked by a top screw, or other structures, which are used for adaptive adjustment after the distance between the center seat and the driving motor is adapted and adjusted. A hinged seat is provided at the end of the knocking arm, and the knocking is hinged on the hinged seat through a pin shaft and can be locked.

[0050] This embodiment adjusts the distance between the center seat and the drive motor through an adjustment mechanism. The adjustment of this process can enable the pressing arm and the knocking arm to have different pressing and knocking strengths and diverse functions to meet the testing requirements of different communication equipment screens.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit it. For example, the type of communication equipment, the knocking head and the pressing head can be in the same plane, and the length of the pressing arm and the knocking arm can be adjusted so that the pressing and knocking are in different depth ranges. Based on this, the present embodiment is also suitable for certain uneven screen detection. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the present invention.
