Description of the invention: [Technical field to which the invention pertains] The present invention relates to the field of circuit board manufacturing, and more particularly to a method for feeding and conveying a material for conveying a circuit board. [Prior Art] With the increasing miniaturization and high-speed performance of electronic products, circuit boards have evolved from single panels to double panels and multilayer boards. Among them, the double-sided circuit board and the multilayer © circuit board have a large wiring area and a high assembly density and are widely used, see the literature: Takahashi, A.; High density multilayer printed circuit board for HITAC M-880; IEEE Trans, on 1992 o Multi-layer circuit board manufacturing including inner layer fabrication, inner layer inspection, press-fitting, drilling, electroplating, fabrication of conductive traces, circuit plating, outer inspection, solder masking, surface processing and cutting molding, etc. Process. In order to improve production efficiency, an automated material transfer device is usually used to transfer the circuit substrate fabricated in the previous process to the workbench of the next process. The currently used conveying devices include fixing devices, transfer mechanisms, loading trays and conveyor belts. The fixture is provided with horizontally arranged rails. The conveyor belt is disposed in the direction in which the guide rail extends. The transfer mechanism includes an adsorption device disposed on the fixture and directly above the loading tray. The adsorption device is horizontally slidable along the guide rail by the drive, vertically moving up and down relative to the loading tray, and vertically moving up and down with respect to the conveyor belt for transferring material from the loading tray to the conveyor belt. Specifically, the transfer process includes the following steps: (1) the adsorption loading 200951052 f moves toward the loading tray until it is connected to the circuit board of the residual load (4), and the device is attached to the circuit board, and then approaches the horizontal rail. • Γίΐΐί 升 movement to keep away from the loading tray, (3) transfer mechanism along the guide rail:: motion 'until it is located directly above the conveyor belt; (4) ❹ sin near the bearing surface of the conveyor belt to make vertical downward movement until the board is placed on the conveyor belt (5) adsorption device (4) 2 horizontal guide rails to make a vertical ascending motion to move away from the conveyor belt; (6) the transfer mechanism to move horizontally along the guide rails until it is above the loading tray, and so on. Thus, the transition period of ρ includes the vertical lifting movement of the adsorption device relative to the loading tray. The horizontal reciprocating movement of the transfer mechanism relative to the guide rail and the vertical lifting movement of the adsorption device relative to the bearing surface of the conveyor belt have a long period and need to be When the adsorption device is used for vertical lifting movement and when the transfer mechanism is horizontally reciprocating, the movement speed of the adsorption device or the transfer mechanism is adjusted in time, which takes a lot of time and is not conducive to improving production efficiency. ❹ [Summary of the Invention] In view of this, it is necessary to provide a conveying device with a short feed cycle and a material conveying method to shorten the conveying time and thereby increase the production efficiency. A conveying device includes a fixing device, a horizontal motion adsorption device, a lifting device, a conveyor belt, and a controller. The fixture includes a horizontally disposed rail. The lifting device is disposed under the rail and includes a carrying device and a first driving device. The first drive means is used to drive the load bearing device up and down relative to the guide rail. The horizontal motion adsorption device is slidably connected to the guide rail and is opposite to the carrying device. The utility model comprises a sliding adsorption device and a sliding adsorption device connected to the 200951052 setting===setting-bearing on the carrying device to move the material to the second transmission: Slide along the lower rail and * special belt. The controller is respectively connected with the sliding adsorption device, the first positioning device and the first driving device, and is configured to control the second driving type adsorption device to suck from the carrier device to slide along the guide rail between the lifting device and throw the material on the conveyor belt, and control The first drive unit drives the load bearing unit up and down with respect to the guide rail. The method for brewing the raw material includes the following steps: using the controller to start the second device and the 'monthly moving adsorption device, so that the bearing device is lifted relative to the sliding type until the sliding adsorption device is adsorbed and supported by the bearing controller Controlling the second driving device to vertically lower the load-carrying phase until the remaining material adsorbed in the bearing device of the sliding adsorption device is separated; controlling the first driving device to drive the sliding adsorption device along the guide rail toward the conveyor belt The object-to-sliding adsorption device is located above the bearing surface of the conveyor belt and throws the object onto the conveyor belt; the controller is used to control the first driving device so that the sliding adsorption device slides along the guide rail toward the bearing 1 1 L::: dynamic adsorption device Directly opposite to the position of the carrying device: for driving the carrier device, the phase loading device is vertically descending relative to the sliding adsorption device to separate the material being sucked from the remaining materials in the carrier device, and 200951052 The sliding suction device sucking the material is thrown on the conveyor belt and then returned to the front of the carrying device directly along the guide rail, so that Relative vertical guide means carrying .- some distance, so that while sliding over the adsorption material of the slide means to draw material 'means thereby replacing the previous technologies conveying means of adsorption carrier means relative vertical movement do embodiment of the transfer material. The time required to transport a material using the material delivery device of the present technical solution is only the time during which the sliding adsorption device moves back and forth along the guide rail between the carrier device and the conveyor belt, and does not include the prior art adsorption device relative to the carrier device. The lifting movement and the suction device (4) take time for the vertical lifting movement of the conveyor belt, thus significantly shortening the conveying time and improving the production efficiency.

The first driver 231 can be a motor, a cylinder or a piezoelectric element for driving the first transmission member 232 to drive the slider 211 to slide back and forth along the sliding slot 1111. The first transmission member 232 can be a telescopic bearing that is common in the art. The lifting device 30 includes a carrying device 31 and a first driving device 32 coupled to the carrying device 31.

The loading plate 312 is connected to the first driving device 32, and is driven by the first driving device 32 to perform vertical lifting movement with respect to the guide rail 11 and the surrounding portion 311. q The first drive unit 32 is placed on the ground and includes a second driver 321 and a second transmission member 322 coupled to the second driver 321 . The second driver 321 can be a motor, a cylinder or a piezoelectric element for driving the second transmission member 322 to drive the loading plate 312 to vertically move up and down relative to the slider 211. The second transmission member 322 can be a telescopic bearing that is common in the art. The conveyor belt 40 has a carrying surface 41 for carrying the material transferred from the accommodating chamber 3111 by the slider 211 and transporting the material to a work station of a designated process. The conveyor belt 40 is disposed in the extending direction of the length of the guide 11 and is located in the interval enclosed by the two guide rails 11 and the connecting rod 13. The height of the conveyor belt 40 is from the ground to absorb 13 200951052. After the material is adsorbed by the nozzle 2111, the material can be directly thrown on the bearing surface 41. It is not necessary to adjust the distance between the section bearing surface 41 and the slider 211. The controller 50 is electrically connected to the second driving device 23, the first driving device 32 and the air extracting device 212, respectively, for controlling the second driving device 23 and the first driving device 32 to operate, thereby controlling the sliding member 211 to slide back and forth along the guide rail 11. And the loading plate 312 performs vertical lifting movement with respect to the suction nozzle 2111. The controller 50 is also used to control the operation of the air extracting device 212 to control the suction and ejection of the nozzle 2111. The conveying device 100 of the present embodiment drives the loading plate by adsorbing the material after the suction nozzle 2111 is adsorbed by the first driving device 32 for driving the loading plate 312 to move vertically relative to the guide rail 11 and the surrounding portion 311. The 312 is vertically lowered from the guide rail 11 to the material adsorbed on the suction nozzle 2111 and separated from the remaining material carried by the loading plate 312 to prevent the materials from rubbing each other and causing damage, and the slider 211 sucking the material is thrown on the trailing edge of the conveyor belt 40. Before the guide rail 11 returns to directly above the carrying device 31, the first driving device 32 is driven to cause the @loading plate 312 to drive the remaining material to rise vertically with respect to the guide rail 11 and the distance of the thickness of the material is removed to slide the sliding member 211 to the loading plate. At the same time as 312, the material is sucked, thereby replacing the prior art conveying device by means of the vertical movement of the sliding member 211 relative to the carrying device 31 to remove the material. Since the thickness of a piece of material is relatively thin, the time required for the carrier material 312 to drive the remaining material relative to the guide 11 to rise vertically equal to the thickness of a piece of material is negligible. Therefore, when the material is conveyed by the conveying device 100 of the embodiment, the time required for one cycle of material transfer is only the time during which the sliding member 211 moves back and forth between the lifting device 30 and the conveyor belt 40 along the guide 11, excluding the time. 14 200951052 The time required for the vertical ascending and descending movement of the prior art adsorption device relative to the lifting device and the vertical ascending and descending movement of the adsorption device relative to the conveyor belt, therefore, greatly shortens the material feeding time and improves the production efficiency. Please refer to FIG. 2' for a schematic diagram of a transport device 200 according to a second embodiment of the present technical solution. The difference from the delivery device is that the sliding adsorption device 221 further includes a holding member 2212. The guide rail 24 is not provided with a chute, and the carrying device 230 does not include the enclosing portion, and only includes the loading plate 233. Each of the four support bars 250 is provided with a sliding groove 2501 disposed along its length. The holder 2212 is fixed to opposite ends of the slider 2211 and sleeved on the rail 240'. The first actuator 235 drives the slider 2211 to slide back and forth along the rail 240. The surface 2212 of the sliding member 2211 opposite to the carrying device 230 is provided with a plurality of through holes (not shown) communicating with the cavity of the sliding member 2211 (not shown). When the vacuum generator 223 is activated, it will extract the sliding portion 2211. The air in the body absorbs the material in the carrying device 230 through the through hole, and does not need to provide a nozzle. The four corners of the loading plate 233 are embedded in the sliding groove 25〇1, and are driven by the first driving device 260 to vertically move up and down along the support bar 250 with respect to the guide rail 24〇. In the feeding device 200 of the embodiment, the four corners of the loading plate 233 are embedded in the sliding groove 25 of the supporting rod 250, so that the loading plate 233 is driven by the first driving device 260 relative to the sliding member 2211. When the vertical ascending and descending movements are performed, the support rod 250 is slid, and the movement track of the loading plate 233 is determined to prevent the load plate 233 from damaging the first driving device 260 due to the material center of gravity offset 15 200951052 during the lifting process. The embodiment directly connects the sliding member 2211 and the surface 2212 opposite to the lifting device 230 to the cavity. The through hole ' cooperates with the vacuum generator 223 to form the adsorption device by using the sliding member 2211, thereby eliminating the need for the nozzle. The structure of the conveying device is simplified. The conveying device of the technical solution is described in detail above, and the conveying method of the technical solution will be described by taking the conveying device 100 as an example. The conveying method comprises the following steps: 'The first driver 231 is activated by the controller 50 to slide the sliding suction device 21 along the guide rail n to a position opposite to the lifting device 30. Referring to Fig. 1 'In this embodiment The first driver 231 is controlled to slide the slider 211 along the sliding slot 1U1 to a position opposite to the loading plate 312, and the projection of the nozzle 2111 relative to the lifting device 3 is located in the loading plate 312. The second driver 321 and the sliding adsorption device 21 are activated by the controller 50 to cause the carrier device 31 to perform a vertical ascending motion with respect to the sliding adsorption device 21 until the sliding adsorption device 21 adsorbs the material carried by the carrier device 31. The second driver 321 controls the second actuator 321 to vertically lower the load-carrying device 31 relative to the sliding adsorption device 21 until the material adsorbed to the sliding adsorption device 21 is separated from the remaining material of the carrier device 31. In this embodiment, the first device needs to be borrowed. The carrier plate 312 is driven by the second driver 321 to rise relative to the slider 211 until the slider 211 adsorbs the material carried on the carrier plate 312 with the aid of the air extracting device 212, and then controls the second driver 321 by using the controller 5, The carrier plate 312 is vertically lowered relative to the sliding member 211' until the material adsorbed to the sliding member 211 is separated from the remainder 16 of the loading plate 312, 200951052. The third step is to control The 〇5 吸附 type adsorption device 21 is moved toward the first driver 231 along the guide rail u, so that the slide-to-sliding suction device 21 is moved in the direction of the burial near conveyor belt 41, and is directly thrown onto the conveyor belt 40. Above the bearing surface 41 of the feeding belt 40 In the present embodiment, by controlling the first driver 231, the slider 211 adsorbing the material is moved along the guide rail u lion until the slider 211 is in the direction of the transport belt 41. ❹ Since the conveyor belt 40 is away from the ground * Above the bearing surface 41. After the material can be directly thrown into the wearing of the material to meet the sliding member 211, the adsorbent saves the sliding member 211 relative to the 偻," Therefore, compared with the prior art, 41 and the sliding member m The distance and the straight drop are adjusted to adjust the bearing surface sink/moon moving member 211 relative to the conveyor belt 4 〇 φ to raise the adsorption device 2111 away from the conveyor belt 40. The fourth step is vertical, and the controller 5 is used to control the first actuator 23 type adsorption device 21 Moving along the guide rail 11 toward the bearing device 31 and simultaneously controlling the second driver 321 and the sliding device 21 by the controller 50, the carrying device 31 is moved vertically to the guide rail U to make the sliding adsorption device When the slide 21 is slid to the position opposite to the carrying device 31, the material is adsorbed at the same time. In this embodiment, since the carrier plate 312 rises relative to the guide 11 by a distance equal to the thickness of the material to be removed before the slider 211 moves above the carrier plate 312, the slider 211 moves to the carrier plate. When 312 is over, the material will be directly adsorbed without the need to lower the sliding member 211 relative to the loading plate 312 as in the prior art, thereby adjusting the distance from the material, thereby eliminating the prior art 17 200951052, the movement of the middle sliding member 211 relative to the loading plate 312. time. ^ After completing the above one feeding cycle, just repeat the steps from step two to step four when conveying the next material.
