[0016] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] As Figures 1 to 3 shown, a desktop vision pick-and-place machine, characterized in that it includes a workbench, longitudinal guide rails 1 are arranged on both sides of the workbench, a transverse guide rail 2 is connected to the upper side of the longitudinal guide rail 1 through a slider, a moving head structure is connected to the upper side of the transverse guide rail 2 through a slider, a plurality of arranged positioning slots 814 are provided on the side of the workbench, a feeder 5 is fixedly arranged at the position of the positioning slot 814, and a detection camera 6 and a PCB bracket 7 are further arranged on the upper side of the workbench.

[0020] Through the longitudinal guide rail 1 and the transverse guide rail 2, the moving head structure can be moved on the upper side of the workbench. Place the PCB board to be pasted at the position of the PCB bracket 7, and then the moving head mechanism 3 takes out the components from the feeder 5 and moves to the corresponding position of the PCB board to complete the pasting. The overall structure is simple, the operation is stable, and the pasting work can be realized at a relatively low production cost, thereby reducing the equipment cost of the enterprise.

[0021] At this time, the moving head structure includes a moving plate 31 fixed to the slider of the transverse guide rail 2. A head motor 32 is arranged on the upper side of the moving plate 31. A plurality of up-and-down moving attaching mechanisms 33 are arranged on the outside of the moving plate 31 through a guide rail slider structure. A swing plate 34 is fixed to the shaft of the head motor 32. Both ends of the swing plate 34 are in contact with the upper sides of the two attaching mechanisms 33. An elastic member for the attaching mechanism 33 to move upward after pressing down is arranged on the lower side of the attaching mechanism 33. The swing plate 34 swings under the action of the head motor 32, so that the attaching mechanism 33 in contact with the swing plate 34 moves up and down.

[0022] In order to control the picking and attaching actions of the attaching mechanism 33 through the head-attaching motor 32, it is necessary to control the up and down movement of the attaching mechanism 33. Therefore, in this embodiment, bearings 35 are respectively provided at both ends of the swing plate 34, and the bearings 35 at both ends of the swing plate 34 are respectively abutted against the upper ends of the two attaching mechanisms 33. At this time, the rotation angle of the head-attaching motor 32 is a certain arc, not a complete circle, and the head-attaching motor 32 rotates reciprocally. In this way, during the rotation of the head-attaching motor 32, the swing plate 34 can swing together. The bearings 35 at both ends of the swing plate 34 will move in an arc, and the bearings 35 have a certain displacement in the vertical direction. In this way, the attaching mechanism 33 abutting against the bearings 35 at both ends of the swing plate 34 can move a certain distance in the vertical direction. Coupled with the action of the elastic member, the attaching mechanism 33 can move up and down reciprocally.

[0023] The attaching mechanism 33 is used to pick up components and then move to the upper side position of the PCB board under the action of the horizontal guide rail 2 and the longitudinal guide rail 1. Therefore, in this embodiment, the attaching mechanism 33 includes a horizontal plate 331 fixed to the outside of the moving plate 31. An adsorption head 332 is provided on the lower side of the horizontal plate 331, and a vacuum pump 333 is provided on the upper side of the adsorption head 332. Under the action of the vacuum pump 333, an adsorption force is generated at the position of the adsorption head 332, so that the components at the feeder 5 position can be picked up. After moving to the upper side of the PCB board, the vacuum pump 333 is disconnected, and the components are placed at the corresponding position on the PCB board. At this time, multiple groups of adsorption heads 332 and corresponding vacuum pumps 333, head-attaching motors 32, and swing plates 34 can be provided to improve the chip mounting efficiency.

[0024] In order to facilitate the positioning of the PCB board, a PCB bracket 7 is provided on the upper side of the PCB board. After the PCB board to be chip-mounted is placed on the PCB bracket 7, the PCB board can be positioned. Specifically, in this embodiment, the PCB bracket 7 includes a first fixing plate 71 and a second fixing plate 72 fixed to the upper side of the workbench. A plurality of connecting rods 73 are provided between the first fixing plate 71 and the second fixing plate 72, and a sliding positioning rod 74 is provided on the connecting rods 73. Positioning steps are provided on the opposite sides of the first fixing plate 71 and the positioning rod 74. The first fixing plate 71 and the second fixing plate 72 are fixed to the workbench. Connecting rods 73 are provided between the first fixing plate 71 and the second fixing plate 72, and the positioning rod 74 slides on the connecting rods 73, so that the distance between the positioning rod 74 and the first fixing plate 71 and the second fixing plate 72 can be adjusted to adapt to PCB boards of different width dimensions. At the same time, when the PCB board is placed between the first fixing plate 71 and the positioning rod 74, in order to better position the PCB board, positioning steps are provided on the opposite sides of the first fixing plate 71 and the positioning rod 74, so that the PCB board can be better fixed and positioned.

[0025] If the size of the PCB board is small and it cannot be placed on the two connecting rods 73 (between the first fixing plate 71 and the positioning rod 74), at this time, there are a plurality of fixing holes provided on the workbench, and positioning blocks 8 are fixed at the positions of the fixing holes by screws. There is a positioning groove 814 on the upper side of the positioning block 8. There are 4 positioning blocks 8, which are distributed in a rectangular shape on the upper side of the workbench. The fixing holes and the positioning blocks 8 are arranged at the inner side position of the connecting rod 73. At the same time, the height of the positioning block 8 does not exceed the height position of the connecting rod 73 to avoid affecting the positioning of the PCB board on the upper sides of the connecting rod 73 and the positioning rod 74 after the positioning block 8 is installed. The positioning groove 814 is provided on the upper side of the positioning block 8. At this time, the positioning groove 814 is a right-angle groove provided on the top plate of the positioning block 8. The two perpendicular sides of the right-angle groove form the positioning groove 814 with the top of the top block, so that the two sides of the positioning groove 814 are perpendicular. A groove extending to the outside is provided at the right-angle position of the right-angle groove to prevent interference when the PCB board is placed at the position of the positioning groove 814, thus affecting the placement of the PCB board.

[0026] When the moving pick-up head structure takes out components, in order to observe the components, in this embodiment, a second detection camera 6 is provided on the side of the moving plate 31 of the moving pick-up head structure. The second detection camera faces downward and can detect the components in the feeder 5 and on the upper side of the workbench in the IC tray, so as to make the attaching process more accurate.

[0027] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0028] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
