[0021] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] according to Figure 1-4As shown, this embodiment proposes a fully automatic needle-installing machine, including a machine body and a control system arranged in the machine body. The machine body is provided with a pointer grabbing device 4 connected to the control system, a human-machine interaction device, a pointer moving device 3 and a pointer fixing device 2, and each device cooperates to complete the installation of the pointer. The pointer fixing device 2 first fixes the hour hand, minute hand and second hand, and the pointer grabbing device 4 grabs each pointer and moves it to the clock dial on the pointer moving device 3. The clock dial is pre-installed on the pointer moving device 3. The fixed installation disk 54 is provided with a groove, and the groove is used to snap into the protrusion set on the back of the dial, so that the dial is fixed on the fixed installation disk 54. Each pointer is installed on the clock dial in turn. After the installation is completed, the human-machine interaction device takes a video of the pointer on the clock dial, and manually observes and inspects whether the three pointers are parallel to each other. If they are parallel, they are qualified products, otherwise they need to be reworked. A shock-proof pad 8 is provided at the bottom of the machine body to prevent the amplitude from being too large when the machine is working, which affects the installation of the pointer.

[0023] The pointer fixing device 2 includes a fixing seat 11 arranged on the machine body, and a pointer material tray and a pointer adjustment mechanism are arranged on the fixing seat 11. The pointer material tray includes an hour hand material tray 12, a minute hand material tray 13 and a second hand material tray 14. The pointer adjustment mechanism includes a fine-tuning slide rail and a fixed slider 15 arranged on the fine-tuning slide rail. An hour hand fixing disk 16, a minute hand fixing disk 17 and a second hand fixing disk 18 with the same structure are arranged in the fixed slider 15. A fixing block 19 is arranged at the end of the fine-tuning slide rail. The fixing block 19 is threadedly connected with a main adjusting screw 20. The main adjusting screw 20 passes through the fixing block 19 and is threadedly connected to the fixed slider 15, and is used to adjust the position of the entire fixed slider 15 so that the hour hand fixing disk 16, the minute hand fixing disk 17 and the second hand fixing disk 18 can be aligned with the grabbing position of the pointer moving device 3 to accurately grab each pointer. The hour hand fixing plate 16 is integrally formed with a driving rod 24, and a first adjusting screw 21 and a second adjusting screw 22 for adjusting the driving rod 24 are provided on both sides of the fixed slider 15, and the opposite ends of the first adjusting screw 21 and the second adjusting screw 22 abut against the driving rod 24. The first adjusting screw 21 and the second adjusting screw 22 are manually adjusted to adjust the ends thereof to squeeze the driving rod 24. Since the driving rod 24 is integrally formed with the base of the pointer clamping mechanism, the base can be rotated by the swing of the driving rod 24 to adjust the placement angle of the pointer placed on the pointer clamping mechanism. The hour hand fixing plate 16 is provided with a limit hole, and a first limit column 25 and a second limit column 26 are arranged in the limit hole. The first limit column 25 and the second limit column 26 are respectively arranged on the first clamping member 27 and the second clamping member 28. One end of the first clamping member 27 and the second clamping member 28 are connected by a spring 31 arranged in the hour hand fixing plate 16, and the other end is in contact with the third adjusting screw 23. The third adjusting screw 23 is threadedly connected to the hour hand fixing plate 16. The other end of the third adjusting screw 23 is provided with an adjusting knob. The hour hand fixing plate 16 is also provided with a fixing column for fixing the pointer head.

[0024] The third adjusting screw 23 is threadedly connected to the fixed base 41, and an adjusting knob is provided at one end away from the first clamping member 27 and the second clamping member 28, and the outer side of the adjusting knob is provided with anti-slip grooves. By manually turning the adjusting knob, the end of the bullet head 30 of the third adjusting screw 23 squeezes the gap between the first clamping member 27 and the second clamping member 28. Before placing the pointer, first adjust to make the gap between the first clamping member 27 and the second clamping member 28 larger. After the pointer is placed, the adjusting knob is reversely rotated to make the gap between the first clamping member 27 and the second clamping member 28 smaller until the tail of the pointer is clamped. Since the head of the pointer is provided with an annular ring, the fixing column is used to clamp the head of the annular ring of the pointer. Through such a structure, the head and tail of the pointer are both clamped, so that the entire pointer is fixed to prevent it from swinging and deviating easily, affecting the subsequent installation work.

[0025] The ends of the first clamping member 27 and the second clamping member 28 that contact the third adjusting screw 23 are provided with guide surfaces 29, and the ends of the third adjusting screw 23 that contact the first clamping member 27 and the second clamping member 28 are in the shape of a bullet head 30. When the first clamping member 27 and the second clamping member 28 that are provided with guide surfaces 29 at the ends contact the third adjusting screw 23 at the end of the bullet head 30, the third adjusting screw 23 can more easily squeeze and separate the first clamping member 27 and the second clamping member 28.

[0026] The pointer grabbing device 4 includes a fixed base 41 arranged on the body, the fixed base 41 is provided with a first direction slide rail 42, the first direction slide rail 42 is snap-connected to the first slider 44, the first slider 44 is connected to the first driving motor 47, a fixed bracket 46 is provided on the first slider 44, a second direction slide rail 43 is provided on the fixed bracket 46, the second direction slide rail 43 is snap-connected to the second slider 45, the fixed bracket 46 is provided with a second driving motor 48 connected to the second slider 45, the second slider 45 is provided with a plurality of adsorption members 50, the adsorption member 50 is provided with an adsorption hole connected to the negative pressure pump, and the adsorption member 50 is threadedly connected to the fourth adjusting screw 49, the fourth adjusting screw 49 is used to thread fine-tune the vertical position of the adsorption member 50 connected thereto, so that the contact position of the adsorption member 50 when adsorbing the pointer is in a more appropriate position. The first driving motor 47 controls the first slider 44 to move on the first direction slide rail 42, and the second driving motor 48 controls the second slider 45 to move on the second direction slide rail 43, so as to adjust the position of each adsorbing member 50, accurately adsorb the pointer and install it on the clock face.

[0027] The human-machine interaction device includes a camera 56 connected to the control system, an operation panel 6, and a display screen 7. The lens of the camera 56 faces the pointer moving device 3. The pointer moving device 3 includes a third directional slide rail 51 arranged on the body, a third slider 52 is inserted into the third directional slide rail 51, a fixed mounting plate 54 is connected to the third slider 52, and the third slider 52 is connected to the driving rod 24 of the third driving motor 55; a pressure sensor 53 connected to the control system is also arranged between the third slider 52 and the fixed mounting plate 54. Every time when the adsorption member 50 of the pointer grabbing device 4 adsorbs the pointer on the fixed mounting plate 54, it must first contact the pointer. There is a squeezing force when there is contact. Since the pointer is a relatively small component, the squeezing force cannot be too large, otherwise the pointer is easily deformed and scrapped. The pressure sensor 53 is connected to the control system, and the control system is connected to the display screen 7. The pressure of the adsorption member 50 squeezing the pointer sensed by the pressure sensor 53 will be displayed in real time on the display screen 7. When the set pressure value is exceeded, the control system controls the second driving motor 48 to drive the adsorption member 50 to rise immediately to avoid damage to the pointer.

[0028] The third driving motor 55 drives the third slider 52 to move on the third directional slide rail 51, and the lens of the camera 56 is aimed at the fixed mounting plate 54. When the clock dial fixed by the fixed mounting plate 54 is installed with each pointer, it is moved to the camera 56 through the third driving motor 55; the camera 56 is connected to the display screen 7 through the control system, and the horizontal view of each pointer taken will be magnified and displayed on the display screen 7. Through manual observation, it can be intuitively seen whether each pointer is in a parallel state. If it is in a parallel state, it is a qualified product, otherwise it needs to be reworked. The operation panel 6 is used to control the operation of each driving motor.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
