DETAILED DESCRIPTION

[0029] The following will be combined with 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.

[0030] like Figure 1 As shown, combined Figure 2The present invention discloses a robot for assembling ribbons of a photo frame back panel support leg, comprising a platform 1, a carrier plate 2, a punching head 3, a feeding mechanism 4 and a first clamping claw 5.

[0031] The carrier plate 2 is arranged on the platform 1. The carrier plate 2 is fixed above the platform 1 through a support rod.

[0032] Two punching heads 3 are arranged on the platform 1 and are located above the carrier plate 2. The punching heads 3 are part of a punching mechanism, and the punching mechanism adopts standard equipment.

[0033] The two robot arms transport the back plate 11 and the legs 12 to the carrier plate 2 and place them respectively under the two punching heads 3. The two robot arms are installed near the platform 1 for loading.

[0034] The feeding mechanism 4 conveys the buckles to between the punch head 3 and the back plate 11 or the support leg 12. The feeding mechanism 4 includes a vibration plate and a guide trough. The vibration plate conveys the buckles one by one to the guide trough. The free end of the guide trough extends to between the punch head 3 and the back plate 11 or the support leg 12 to realize the feeding of the buckles.

[0035] The first clamping jaw 5 clamps the ribbon 13 and places it between the back plate 11 or the legs 12. The first clamping jaw 5 is driven by a cylinder or an electric cylinder to realize the clamping action.

[0036] During the operation, the robot arm first places the back plate 11 and the support leg 12 on the carrier plate 2, and the carrier plate 2 is provided with a positioning block to limit the position of the back plate 11 and the support leg 12, and then the feeding mechanism 4 feeds the buckle, and the first clamp 5 feeds the ribbon 13 at the same time, and the two ends of the ribbon 13 are respectively located between the buckle and the upper surface of the back plate 11 and between the buckle and the upper surface of the support leg 12; the two punching heads 3 punch synchronously, and fix the two ends of the ribbon 13 on the back plate 11 and the support leg 12 respectively through the buckle. Through the above design, the automatic feeding and positioning of the back plate 11, the support leg 12, the ribbon 13 and the buckle assembly parts are completed, so that the unmanned buckle assembly operation of the ribbon of the back plate support leg of the photo frame can be realized.

[0037] exist Figure 4 In a preferred embodiment shown, in order to enable the first clamping jaw 5 to pick up and feed the ribbon 13, a feeding component 6 and a movable part 7 are also included.

[0038] The platform 1 is provided with a first station and a second station at the front and rear. The loading assembly 6 is provided on the platform 1, and the loading assembly 6 and the carrier plate 2 are provided at the first station and the second station respectively.

[0039] The movable part 7 is arranged on the platform 1 and translates the feeding assembly 6 on the platform 1 to feed the ribbon 13 to the second station; the movable part 7 reciprocates between the first station and the second station.

[0040] When the above technical solution is adopted, the first clamp 5 is set on the movable part 7 and moves synchronously with the movable part 7. The first clamp 5 rotates around the movable part 7 and faces the first station or the second station. The first clamp 5 moves to the second station and clamps the ribbon 13.

[0041] exist Figure 2 In a preferred embodiment shown, when the movable part 7 moves from the first station toward the second station and moves to the center of the two stations, the first clamp 5 rotates from the side of the movable part 7 toward the first station to the side of the movable part 7 toward the second station; when the movable part 7 moves from the second station toward the first station and moves to the center of the two stations, the first clamp 5 rotates from the side of the movable part 7 toward the second station to the side of the movable part 7 toward the first station; the first clamp 5 does not directly flip forward and backward to complete the loading of the ribbon 13, but after rotating to the corresponding station, it needs to be translated for a distance before taking and loading the material.

[0042] exist Figure 5 and Figure 6 In a preferred embodiment shown, after the first clamp 5 clamps the ribbon 13, when it rotates to the direction toward the first station, the first clamp 5 needs to move forward to deliver the ribbon 13 to the carrier 2. At this time, due to the softness of the ribbon 13, both ends of the ribbon 13 will fall freely, causing the two ends of the ribbon 13 to bend and fall from both sides of the first clamp 5. This causes the ends of the ribbon 13 to rub against the carrier 2 when the first clamp 5 moves forward to move the ribbon 13 to the carrier 2, and the ends of the ribbon 13 are folded instead of being completely flattened when they are in place, which makes it impossible to complete the stamping of the ribbon 13. Therefore, this embodiment also includes a guide bar 8.

[0043] A notch 201 is formed on the carrier plate 2 , and the first clamping jaw 5 moves to the first station and enters the notch 201 . A back plate 11 and legs 12 are disposed on both sides of the notch 201 .

[0044] The two guide strips 8 are respectively arranged on both sides of the notch 201, one end of the guide strip 8 is arranged on the carrier plate 2, and the other end of the guide strip 8 extends toward the second workstation, the extension direction of the guide strip 8 intersects with the moving direction of the movable part 7, the free end of the guide strip 8 is close to the side of the first clamp 5 and the distance between the free ends of the two guide strips 8 is smaller than the distance between the fixed ends of the two guide strips 8, so that the free end of the guide strip 8 is as close as possible to the side of the first clamp 5 so that the free end can be inserted under the bending part of the end of the ribbon 13, otherwise the ribbon 13 cannot be guided to be flattened.

[0045] When the above technical solution is adopted, when the first clamp 5 rotates and faces the first workstation, the two ends of the ribbon 13 fall freely, and the first clamp 5 moves toward the first workstation, so that the end of the guide bar 8 contacts the lower surface of the ribbon 13. As the first clamp 5 continues to move toward the first workstation, the freely falling end of the ribbon 13 is gradually flattened by the guide bar 8, and finally the ribbon 13 moves onto the carrier plate 2 in a flattened state.

[0046] exist Figure 7 In a preferred embodiment shown, the extension direction of the guide strip 8 is inclined relative to the surface of the platform 1, and the free end of the guide strip 8 extends toward the platform 1, so that the free end of the guide strip 8 extends downward so that the free end can be inserted under the bending part of the end of the ribbon 13, otherwise the ribbon 13 cannot be guided to be flattened.

[0047] exist Figure 8 In a preferred embodiment shown, in order to realize the material picking and feeding action of the first clamping jaw 5, a guide plate 9, a rotating arm 91 and a roller 92 are also included.

[0048] The guide plate 9 is arranged on the platform 1 and its two ends extend toward the two workstations. The plate surface of the guide plate 9 is perpendicular to the platform 1. The guide plate 9 is provided with a slide groove 901, which is composed of two horizontally extending parts and an arc-shaped part connected between the two horizontally extending parts, and the arc-shaped part protrudes toward one side of the platform 1.

[0049] The middle axis of the rotating arm 91 is connected to the movable part 7 ; the first clamping jaw 5 is provided at the other end of the rotating arm 91 , so that the first clamping jaw 5 and the roller 92 can rotate axially around the movable part 7 through the rotating arm 91 .

[0050] The roller 92 is disposed at one end of the rotating arm 91 ; the roller 92 is disposed in the slide groove 901 and rolls along the slide groove 901 .

[0051] When the above technical solution is adopted, when the roller 92 moves in the horizontal extension part of the slide groove 901, the rotating arm 91 does not rotate, but the first clamping jaw 5 extends horizontally and translates; and when the roller 92 passes through the arc portion of the slide groove 901, the roller 92 moves along the concave arc, driving the rotating arm 91 to rotate, and driving the first clamping jaw 5 to complete a 180° rotation.

[0052] exist Figure 3 In a preferred embodiment shown, specifically, the feeding assembly 6 includes a winding mechanism 61 , a second clamping jaw 62 , a third clamping jaw 63 and a cutting mechanism 64 .

[0053] The winding mechanism 61 and the second clamping jaw 62 are respectively arranged on both sides of the moving direction of the movable part 7, and the winding mechanism 61 winds the ribbon 13 and is provided with a pull-out end of the ribbon 13. The winding mechanism 61 adopts standard equipment.

[0054] The second clamping jaw 62 moves horizontally in a direction perpendicular to the moving direction of the movable portion 7, and the second clamping jaw 62 clamps the pulled-out end of the ribbon 13 and pulls the ribbon 13 horizontally out of the winding mechanism 61. The second clamping jaw 62 uses a cylinder or an electric cylinder to achieve the clamping action.

[0055] The third clamping jaw 63 is arranged between the winding mechanism 61 and the second clamping jaw 62, and the third clamping jaw 63 clamps the pulled-out portion of the ribbon 13. The third clamping jaw 63 is two sliders installed on a vertically arranged slide rail, and the third clamping jaw 63 includes two claw bodies 631, and the two claw bodies 631 are respectively installed on the two sliders, and the two sliders are driven to move relative to each other by the telescopic gas rod, so as to realize the opening and closing of the two claw bodies 631 of the third clamping jaw 63.

[0056] When the above technical solution is adopted, the second clamp 62 first clamps the pulled-out end of the ribbon 13 and pulls the ribbon 13 horizontally out of the winding mechanism 61, then the third clamp 63 clamps the middle part of the pulled-out part of the ribbon 13, and then the cutting mechanism 64 cuts the ribbon 13, so that the pulled-out part of the ribbon 13 is separated from the winding mechanism 61; then the first clamp 5 clamps the cut ribbon 13, and then the second clamp 62 and the third clamp 63 release the ribbon 13, completing the material picking action of the first clamp 5.

[0057] exist Figure 4 In a preferred embodiment shown, the cutting mechanism 64 is a heating wire. Specifically, the cutting mechanism 64 is installed on a lifting block. Two pillars are arranged at intervals on the lifting block. Both ends of the heating wire are fixed on the two pillars. The heating wire is electrically connected to a heater to heat the heating wire. The cutting mechanism 64 moves in the vertical direction of the platform 1 and cuts off the ribbon 13 through high temperature.

[0058] exist Figure 2 In a preferred embodiment shown, since the third jaw 63 may block the moving path of the second jaw 62 when the second jaw 62 translates and moves toward the winding mechanism 61, the third jaw 63 includes two claw bodies 631, and the two claw bodies 631 approach each other and clamp the ribbon 13 or move away from each other and release the ribbon 13; when the two claw bodies 631 move away from each other, the second jaw 62 passes between the two claw bodies 631 and moves toward the winding mechanism 61, thereby avoiding obstruction to the translation of the second jaw 62.

[0059] like Figure 1 As shown, combined Figure 2 The method for using a robot for assembling ribbons of a photo frame back panel support leg of the present invention adopts a robot for assembling ribbons of a photo frame back panel support leg of any of the above embodiments, comprising the following steps:

[0060] In step one, the robot arm transports the back plate 11 and the supporting legs 12 to the carrier plate 2 and places them respectively under the two punching heads 3. When the movable part 7 moves from the first station toward the second station and moves to the center of the two stations, the first clamp 5 rotates from the side of the movable part 7 toward the first station to the side of the movable part 7 toward the second station and continues to move.

[0061] Step 2, the loading assembly 6 loads the ribbon 13 to the second station. After the first clamp 5 clamps the ribbon 13, when the movable part 7 moves from the second station toward the first station and moves to the center of the two stations, the first clamp 5 rotates from the side of the movable part 7 toward the second station to the side of the movable part 7 toward the first station and continues to move. When the first clamp 5 rotates and moves toward the first station, the two ends of the ribbon 13 will fall freely. Since the chute 901 is composed of two horizontally extending parts and an arc-shaped part connected between the two horizontally extending parts, when the first clamp 5 moves toward the first station and passes through the horizontally extending part chute 901 close to the first station, the end of the guide bar 8 will contact the lower surface of the ribbon 13. As the first clamp 5 continues to move toward the first station, the free-falling end of the ribbon 13 is gradually flattened by the guide bar 8, and finally the ribbon 13 moves to the carrier plate 2 in a flattened state.

[0062] Step three, the feeding mechanism 4 conveys the buckle to between the punching head 3 and the back plate 11 or the support leg 12, and the two punching heads 3 punch synchronously to fix the two ends of the ribbon 13 on the back plate 11 and the support leg 12 respectively through the buckle.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
