[0038] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present application and with reference to the accompanying drawings.

[0039] As Figure 1-2 shown, an automatic ornament placing device based on MIM technology includes: a workpiece moving component 1, a workpiece discharging component 2, a visual component 3, a ceramic sheet discharging component 4, a ceramic sheet moving component 5 and a working head 8;

[0040] The workpiece discharging component 2 is used to flatten the workpiece, and the visual component 3 is used to obtain the position information and angle information of the flattened workpiece;

[0041] A number of ceramic sheets 7 are stacked inside the ceramic sheet discharging component 4, and the ceramic sheet discharging component 4 is used to provide a single ceramic sheet 7 to the ceramic sheet moving component 5, and the ceramic sheet moving component 5 is used to move the ceramic sheet 7 to a preset position;

[0042] The working head 8 is arranged on the workpiece moving component 1, the working head 8 is used to adsorb the workpiece and adjust the angle of the workpiece, and the workpiece moving component 1 is used to move the working head 8 so that the working head 8 places the workpiece on the ceramic sheet 7 on the ceramic sheet moving component 5.

[0043] A frame (not shown in the figure) is provided at the lower part of each of the above components, so that the heights of the components cooperate with each other. The specific setting of the frame is not limited and will not be elaborated here.

[0044] Working process: First, after the workpiece discharging component 2 flattens the workpieces, it stops discharging. The ceramic sheet discharging component 4 provides a single ceramic sheet 7 to the ceramic sheet moving component 5. The ceramic sheet moving component 5 moves the single ceramic sheet 7 to a preset position. The vision component 3 acquires the position information and angle information of all the workpieces below. The workpiece moving component 1 moves the working head 8 according to the position information acquired by the vision component 3, so that the working head 8 adsorbs the workpiece, and the working head 8 adjusts the angle of the workpiece according to the angle information of the vision component 3. The moving component 1 moves the working head to the ceramic sheet 7 on the ceramic sheet moving component 5 and arranges it according to a preset array. After a batch of workpieces are arranged, the workpiece discharging component 2 discharges again to avoid stacking and residue of workpieces. After the workpieces on a single ceramic sheet 7 are filled, the ceramic sheet moving component 5 removes the ceramic sheet 7 filled with workpieces, and the ceramic sheet discharging component 4 pushes out a new ceramic sheet 7 for arranging.

[0045] The above working process is controlled by an external control device to coordinate the working actions of each component.

[0046] As Figure 2-3 shown, the workpiece moving component 1 includes: a first electric guide rail 101, a second electric guide rail 102, and a first cylinder 103; the second electric guide rail 102 is arranged on the first electric guide rail 101, the first cylinder 103 is arranged on the second electric guide rail 102, and the working head 8 is arranged at the extending end of the first cylinder 103;

[0047] The first electric guide rail 101 is used to drive the second electric guide rail 102 to move horizontally, the second electric guide rail 102 is used to drive the first cylinder 103 to move vertically, and the first cylinder 103 is used to drive the working head 8 to move vertically.

[0048] As Figure 2-3 shown, the workpiece discharging component 2 includes: a support plate 201, an installation table 202 is arranged on the support plate 201, a storage box 203 is arranged on the installation table 202, one side of the storage box 203 is open, an unfolding box 204 is arranged on the open side of the storage box 203, and the storage box 203 is inclined towards the unfolding box 204, and a vibration motor 205 is arranged at the bottom of the support plate 201.

[0049] In a specific embodiment, the opening part of the storage box 203 is constricted to prevent too many workpieces from falling into the unfolding box 204 at one time, causing stacking and affecting subsequent placement. The specific working principle is that the vibration motor 205 works, drives the storage box 203 to vibrate through the support plate 201. The storage box 203 is inclined, and the workpieces inside fall into the unfolding box 204 through the opening. The unfolding box 204 also vibrates, so that the workpieces inside are flattened and unfolded, facilitating the vision component 3 to acquire the position information and angle information of the workpieces.

[0050] As shown Figure 2-3 in the figure, the vision component 3 includes a support rod 301 and a mounting plate 302. The support rod 301 is vertically arranged on the support plate 201. The mounting plate 302 is arranged on one side of the support rod 301 and above the unfolding box 204. A camera and a light-emitting plate are arranged on the lower surface of the mounting plate 302.

[0051] In a specific embodiment, the color of the unfolding box 204 is different from that of the workpiece. The color of the unfolding box 204 is white, and the color of the workpiece is grayish black, so as to prevent the camera from failing to recognize the workpiece.

[0052] As shown Figure 2-3 in the figure, the ceramic sheet discharging component 4 includes a second air cylinder 401 and a stacking groove 402. The stacking groove 402 is arranged on the support plate 201. The inner cavity shape of the stacking groove 402 corresponds to that of the ceramic sheet 7. Discharging ports 403 are formed at the bottoms of two opposite side walls of the stacking groove 402. A second air cylinder 401 is correspondingly arranged at one discharging port 403, and a ceramic sheet moving component 5 is correspondingly arranged at the other discharging port 403.

[0053] Working principle: When it is necessary to discharge the ceramic sheet, the second air cylinder 401 extends, enters the inside of the stacking groove 402 through the discharging port 403, and pushes the lowermost ceramic sheet 7 out from the other discharging port 403, so that the ceramic sheet 7 falls on the ceramic sheet moving component 5. In a specific embodiment, avoiding grooves are formed on the two side walls of the stacking groove 402 where the discharging ports 403 are not opened, which is convenient for workers to always support the ceramic sheet 7 with their hands until the ceramic sheet 7 is placed completely. Such a setting can prevent the ceramic sheet 7 from being damaged due to too much impact.

[0054] As shown Figure 2-3 in the figure, the ceramic sheet moving component 5 includes a first mounting frame 501. First rollers 502 are respectively rotatably connected to both sides of the first mounting frame 501. A conveyor belt 503 is arranged on the two first rollers 502.

The cooperation of the driving motor, the belt pulley assembly and the roller is a conventional setting for those skilled in the art and will not be elaborated here.

[0055] In a specific embodiment, a deviation rectifying component is arranged on one side of the conveyor belt 503 to perform deviation rectifying processing on the ceramic sheet 7. The deviation rectifying component can adopt a conventional deviation rectifying device in the prior art and will not be elaborated here.

[0056] As shown Figure 4As shown in the figure, the working head 8 includes: a connecting plate 801, which is fixedly connected to the extending end of the first cylinder 103. On one side of the connecting plate 801, there is an installation ring 802. A suction pipe 803 is rotatably connected to the installation ring 802. A first pulley 804 is fixedly connected to the upper part of the suction pipe 803. A rotary joint 805 is arranged at the upper end of the suction pipe 803, and the rotary joint 805 is connected to an external vacuum generator. A rotating motor 806 is fixedly connected to one side of the connecting plate 801, and a second pulley 807 is fixedly connected to the extending end of the rotating motor 806. A belt 808 is arranged between the first pulley 804 and the second pulley 807.

[0057] Working principle: When the workpiece moving assembly 1 moves the working head 8 to a position where it cooperates with the workpiece, that is, when the lower end of the suction pipe 803 abuts against the preset grasping prefabrication of the workpiece, the external vacuum generator works, so that a suction force is generated at the lower end of the suction pipe 803 to adsorb the workpiece. Then the first cylinder 103 contracts to lift the working head 8 with the workpiece. After lifting, the rotating motor 806 rotates a certain angle according to the angle information of the vision assembly 3, driving the suction pipe 803 to rotate, so that the workpiece rotates into a preset posture. After the workpiece rotation is completed, the workpiece moving assembly 1 moves the working head 8 above the ceramic sheet 7 on the ceramic sheet moving assembly 5 again. Then the external vacuum generator is turned off, so that the suction force at the lower end of the suction pipe 803 disappears, and the workpiece falls on the ceramic sheet 7; Specifically, when placing the workpiece, the height between the workpiece and the ceramic sheet 7 can be set according to the specific experience of the worker without damaging the workpiece, and the workpiece does not move when placed; The external vacuum generator can specifically be a combination of a vacuum pump, an air pipe, and an electromagnetic valve, which is a conventional setting for those skilled in the art and will not be elaborated here. The same applies to each cylinder.

[0058] As Figure 5 shown in the figure, a ceramic sheet placing assembly 6 is arranged on one side of the ceramic sheet moving assembly 5 in a matching manner;

[0059] The ceramic sheet placing assembly 6 includes: a second mounting frame 601. On both sides of the second mounting frame 601, there are second rollers 602 rotatably connected respectively. Between the two second rollers 602, there are several conveying strips 603. A driving motor is arranged in cooperation with any one of the second rollers 602, and the driving motor is in cooperation with the second roller 602 through a pulley assembly;

[0060] On one side of the second mounting frame 601, there is a support frame 604. On the support frame 604, there is a third electric guide rail 605. On the third electric guide rail 605, there is a third cylinder 606. The extending end of the third cylinder 606 is provided with a vacuum suction plate 607;

[0061] The third electric guide rail 605 extends above the ceramic sheet moving assembly 5. The third electric guide rail 605 is used to drive the third cylinder 606 to move along the width direction of the second mounting bracket 601, and the third cylinder 606 is used to drive the vacuum suction plate 607 to move in the vertical direction;

[0062] Vacuum suction nozzles are provided at the four corners of the vacuum suction plate 607, and the vacuum suction nozzles cooperate with an external vacuum generator.

[0063] In a specific embodiment, the ceramic sheet placement assembly 6 is used to place and move the ceramic sheet 7 filled with workpieces, so as to further reduce the need for manual labor. The specific working process is as follows: The ceramic sheet moving assembly 5 transports the ceramic sheet 7 filled with workpieces to a preset position at the end of the first mounting bracket 501 through the conveyor 503. This preset position corresponds to the adsorption position of the vacuum suction plate 607. There are vacuum suction nozzles at the four corners of the lower surface of the vacuum adsorption plate 607, and no workpieces are placed at the corresponding positions on the ceramic sheet 7. The vacuum adsorption plate 607 moves the ceramic sheet 7 onto the conveyor strip 603 through the cooperation of the third electric guide rail 605 and the third cylinder 606. After a row is filled, the drive motor drives the second roller 602 to rotate, and the conveyor strip 603 on the second roller 602 drives the ceramic sheet 7 to move, clearing the placement position of the vacuum adsorption plate 607 and waiting for the subsequent placement of the ceramic sheet 7.

[0064] The above are only the preferred embodiments of the present invention.
