[0002] In the manufacturing field, 3C products have occupied a large share, and with the continuous increase of intelligent terminals, this share is still increasing. The rising demand for products has prompted manufacturers to have higher and higher requirements for efficiency. For example, in the mounting industry, it is required that equipment with different processes can achieve connection operation to form a streamlined operation to achieve the purpose of increasing production capacity.

[0003] When the existing automated equipment is in connection operation, after the auxiliary materials are mounted, there will be a problem that the tray carrying the auxiliary materials cannot be recycled in this equipment, or it can be recycled in this equipment, but the tray cannot be classified into the tray at the feeding place. This results in low operating efficiency of the equipment, inability to achieve good circulation and recycling of the trays, and waste of manpower and other problems. Summary of the Invention

Detailed implementation manners

[0052] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0053] Figure 1 It is a schematic structural diagram of a material conveying mechanism for mounting provided in an embodiment of the present application. The material conveying mechanism for mounting provided in the present application may include a pusher device 100, a tray transfer device 200, a tray storage device 300, a carrier rail 400, a hook material device 500, a return material device 600, a tray lifting device 700, and a feeding manipulator device 900.

[0054] The tray storage device 300 and the tray transfer device 200 are arranged opposite to each other. The tray transfer device 200 clamps the magazine 212 containing a plurality of trays 213 output from the storage bin of the tray storage device 300 and transfers the magazine 212 to the front end of the pusher device 100.

[0055] The pusher device 100 and the input end of the carrier rail 400 are arranged opposite to each other. The pusher device 100 pushes the tray 213 in the magazine 212 at the front end out of the magazine 212 by half and then resets.

[0056] The hook material device 500 is installed on the carrier rail 400, hooks the tray 213 that has been pushed out of the magazine 212 by half, and completely pulls the tray 213 into the conveying device of the carrier rail 400 from the material conveying bin 212.

[0057] The tray lifting device 700 is located at the rear end of the carrier rail 400. The feeding manipulator device 900 is installed on the side plate at the rear end of the carrier rail 400. The return material device 600 is located below the front conveying surface of the carrier rail 400.

[0058] After the tray lifting device 700 rises, it is docked with the conveying surface of the carrier rail 400. The feeding manipulator device 900 moves the tray 213 on the conveying device according to the mounting progress of the mounting head, so that the second workpiece to be mounted in the tray 213 is always directly below the mounting head. The mounting head sequentially grabs and places the second workpiece in the tray 213 on a station of the turntable device 800. The turntable device 800 rotates, and another mounting head grabs the second workpiece placed on the turntable device 800 and attaches the second workpiece to the first workpiece.

[0059] After the second workpiece in the tray 213 on the to-be-carried track 400 is grasped, the feeding manipulator device 900 pushes the empty tray on the conveying surface of the carrying track 400 onto the tray lifting device 700. After the tray lifting device 700 descends, the material returning device 600 pushes the empty tray on the tray lifting device 700 onto the return track below the carrying track 400, and then continues to push the empty tray into the magazine 212 clamped by the tray transfer device 200. After the trays 213 in the magazine 212 are rotated and processed, the tray transfer device 200 pushes the clamped magazine 212 into the storage bin of the tray storage device 300.

[0060] Figure 2A It is a structural schematic diagram of the pushing device provided in an embodiment of the present application. The pushing device 100 provided by the present application may include: a column 101, a pushing cross plate 102, a pushing mounting plate 103, a pushing motor 104, a driving synchronous pulley 105, a pushing synchronous belt 106, a driven synchronous pulley 107, a slider adapter block 108, a pushing rod mounting plate 109, a linear guide rail mechanism 112, a pushing rod 113, and a front support 114 for the pushing rod.

[0061] The pushing cross plate 102 is fixedly connected to the upper end of the column 101 and is perpendicular to the column 101. The pushing mounting plate 103 is fixedly connected above the pushing cross plate 102. The pushing motor 104 is fixedly connected to the lower surface of the first end of the pushing mounting plate 103, and the motor shaft of the pushing motor 104 passes through the mounting hole opened on the pushing mounting plate 103.

[0062] The driving synchronous pulley 105 is fixedly connected to the motor shaft of the pushing motor 104. The driven synchronous pulley 107 is rotatably connected to the upper surface of the second end of the pushing mounting plate 103 and is arranged opposite to the driving synchronous pulley 105. The driving synchronous pulley 105 and the driven synchronous pulley 107 are drivingly connected by the pushing synchronous belt 106.

[0063] The guide rail of the linear guide rail mechanism 112 is fixed on the upper surface of the pushing mounting plate 103 and is located on the side of the pushing synchronous belt 106. The slider of the linear guide rail mechanism 112 is fixedly connected to the slider adapter block 108. The slider adapter block 108 is slidably connected to the pushing mounting plate 103 through the linear guide rail mechanism 112, and the slider adapter block 108 is fixedly connected to the synchronous belt through a fastener.

[0064] One end of the pushing rod 113 is fixed to the pushing rod mounting plate 109, and the other end of the pushing rod 113 passes through the mounting hole of the front support 114 for the pushing rod fixed on the pushing mounting plate 103.

[0065] Optionally, the pusher device 100 may further include: two pusher springs 110 and two guide posts 11, where: the two guide posts 11 are fixedly connected inside the slider adapter block 108, and the pusher rod mounting plate 109 is sleeved on the guide posts 11 through mounting holes and is configured to slide linearly along the guide posts 11; the two pusher springs 110 are respectively sleeved on the two guide posts 11, one end of the pusher spring 110 abuts against the slider adapter block 108, and the other end of the pusher spring 110 abuts against the pusher rod mounting plate 109.

[0066] When the pusher device 100 pushes the tray 213, the pusher motor 104 rotates to drive the synchronous belt device, and the pusher synchronous belt 106 drives the slider adapter block 108 connected thereto to move along the linear guide mechanism 112. When the slider adapter block 108 moves, it drives the pusher rod 113 fixed on the pusher rod mounting plate 109 to move forward. When the pusher rod 113 moves forward, it pushes the tray 213 in the bin 212 to discharge materials, as Figure 2B shown, which is a schematic structural diagram of the pusher rod 113 when it is pushed out in the pusher device 100 provided in an embodiment of the present application. At this time, the pusher rod 113 extends forward.

[0067] When the tray 213 is stuck or blocked, the thrust required for the pusher rod 113 to push the tray 213 forward is greater than the elastic force of the pusher spring 110, and the pusher spring 110 is compressed. The pusher rod mounting plate 109 moves backward along the two guide posts 11, and the photoelectric blocking piece 515 fixedly connected to the pusher rod mounting plate 109 is inserted into the photoelectric sensor 514. The photoelectric sensor 514 emits a signal to stop pushing the material, and the pusher motor 104 stops rotating, protecting the tray 213 from damage or other components of the equipment from being damaged.

[0070] The two lower clamping jaws 207 of the tray are fixed on both sides of the transverse movable plate 204. The clamping jaw motor 208 is installed inside the transverse movable plate 204. The motor shaft of the clamping jaw motor 208 is connected to the lead screw 209. The upper clamping jaw mounting plate 210 is connected to the lead screw nut of the lead screw 209. The two upper clamping jaws 211 are fixedly connected in parallel to the positions at both ends above the upper clamping jaw mounting plate 210. The clamping jaw motor 208 drives the lead screw nut of the lead screw 209 to move downward, so as to drive the upper clamping jaws 211 to move towards the lower clamping jaws 207 of the tray, realizing the clamping of the bin 212.

[0072] When the tray transfer device 200 needs to perform a longitudinal linear motion on the bin 212, the longitudinal linear module 201 drives the longitudinal movable plate 202 connected thereto to move, thereby completing the longitudinal movement of the bin 212. When the tray transfer device 200 needs to perform a transverse linear motion on the bin 212, the transverse linear module 206 drives the transverse movable plate 204 connected thereto to move, thereby completing the longitudinal movement of the bin 212. When it is necessary to complete the clamping of the bin 212, the clamping jaw motor 208 operates, driving the lead screw nut of the lead screw 209 to move downward. The lead screw nut drives the upper clamping jaw mounting plate 210 and the upper clamping jaws 211 fixedly connected thereto to move downward, completing the clamping of the bin 212.
