Description

Technical Field

[0001] The present invention relates to the field of chip inductor processing equipment, and more specifically, to a feeding device for chip inductor pad printing processing. Background Art

[0002] In the production and processing of chip inductors, pad printing is one of the links; the current pad printing feeding equipment mainly feeds materials to the material board through a vibrating feeding tray, and multiple material troughs are set on the material board. The workpiece is transported to each material trough by horizontally moving the material board or horizontally moving the vibrating feeding tray. For example, the patent CN216183667U adopts the above method, which realizes rapid feeding through multiple vibrating feeding trays, and realizes alignment and connection between the moving vibrating feeding tray and the material trough to complete the delivery of the workpiece to the material board;

[0003] This method also has an obvious defect. It uses multiple vibrating loading trays for feeding. One vibrating loading tray corresponds to several material troughs in an area for feeding. If one of the vibrating loading trays, especially the one near the edge, fails, the material trough in the area can only be fed by expanding the lateral movement range, which will affect the feeding speed of other parts. And the premise is that the equipment has a large enough lateral movement range. Otherwise, the effect of supplying and replenishing materials cannot be achieved. Therefore, it needs to be improved.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0030] like Figures 1 to 3 As shown, a specific embodiment of the present invention discloses a loading device for pad printing processing of chip inductors, including a discharge tray 100, a material guide tray 200, an industrial camera 300, a material transfer device 600, and a plurality of vibrating loading trays 400; the vibrating loading tray 400 is used to arrange the workpieces and send them to the material guide tray 200, and the material trough of the material guide tray 200 is correspondingly connected with part of the material trough of the arrangement tray 100; the industrial camera 300 is used to photograph the material guide tray 200 and the discharge tray 100 to obtain the arrangement of the workpieces; the material transfer device is used to adjust the position of the workpiece.

[0031] The above-mentioned loading equipment for pad printing processing of chip inductors realizes the transfer and arrangement of workpieces by adding a special material transfer device. There is no need to change the position of the discharge tray, the guide tray, and the vibrating loading tray to realize the conduction and change of the conveying part. The overall structure can be made more compact, and it can also cope with the situation where the vibrating loading tray is damaged, effectively ensuring the overall loading efficiency.

[0032] Furthermore, it includes four vibrating loading trays 400; the guide tray 200 is provided with four first material troughs 210 running through both ends corresponding to the vibrating loading tray 400, and the ends of the four first material troughs 210 are respectively connected with the discharge ports of the four vibrating loading trays 400; multi-point loading is realized, and the overall loading speed is effectively improved; a plurality of evenly spaced second material troughs 110 are provided on the discharge tray 100, and the second material troughs are open at one end close to the guide tray, and the ports of four of the second material troughs 110 are connected to the ends of the first material troughs 210 to achieve partial conduction and maintain smooth feeding, so as to provide sufficient workpieces for replenishing other material troughs. The other end of the second material trough is blocked as the end position of the workpiece arrangement. The workpiece stops after moving to this position, which is used to cooperate with external transfer equipment. The material moving device 600 is arranged above the discharge tray 100 and the guide tray 200, and is used to transfer the workpiece on the guide tray to the discharge tray, and is also used for arranging and adjusting the workpiece on the guide tray, providing sufficient mobile coverage to ensure the required adjustment of the workpiece at the position; the industrial camera 300 is arranged above the material moving device 600, providing a sufficiently large shooting range for shooting the arrangement of the workpiece on the guide tray and the discharge tray, so as to facilitate the coordinated movement of subsequent components.

[0033] Furthermore, if Figure 3 As shown, a pressure plate 130 is installed on the top of one end of the discharge tray 100 away from the vibrating loading tray 400, and a row of single feeding ports 140 are formed at the end of the second material trough, and the shape of the feeding port is adapted to the shape of the workpiece; the width of the pressure plate is at least greater than the sum of the side lengths of the three workpieces; by setting a separate feeding port in the empty space of the pressure plate, it can effectively prevent the external transfer equipment from colliding with other workpieces when grabbing the workpiece; a plurality of first infrared sensors 150 for monitoring the workpiece are installed on the side of the pressure plate 130 away from the feeding port, and the number of the first infrared sensors 150 is the same as the number of the second material trough 110, and the positions correspond; it is used to assist in monitoring the arrangement of the workpieces. When a workpiece is detected at this position, it means that at least several workpieces are arranged in front, and normal workpiece picking and placing can be maintained; if no workpiece is detected at this position, it means that the overall operation may fail, including but not limited to problems with the vibrating loading tray, the material transfer device, etc., resulting in incomplete material replenishment, and an alarm can be sounded through an external alarm to remind the machine control personnel to check and adjust in time.

[0034] Furthermore, if Figure 4 , Figure 5 As shown, a first through hole 111 is provided at the bottom of one end of the second trough 110 away from the vibrating loading tray. The first through hole 111 is located on the upstream side of the material taking port 140. The distance between the center of the first through hole and the center of the material taking port is consistent with the center distance of the two connected workpieces. A clamping structure 500 is installed on the bottom surface of the discharge tray 100. Figure 6As shown, the clamping structure 500 includes a first cylinder 510, a support plate 520 is installed at the end of the piston rod of the first cylinder 510, and a plurality of first push rods 530 are fixedly provided on the top surface of the support plate 520. The position of the first push rod 530 corresponds to the position of the first through hole 111 and the shape is adapted. The first cylinder is used to drive the first push rod to move upward, so as to clamp and fix the workpiece arranged in the second position; this structural design is mainly to cooperate with the external transfer equipment to operate. In the process of the transfer equipment grabbing the workpiece at the material taking port, the clamping structure needs to maintain the force on the second workpiece, so that the workpiece is clamped between the first push rod and the pressure plate, so as to prevent the second workpiece from being offset with the first workpiece, and also avoid affecting the removal of the first workpiece, so as to ensure the normal operation of the overall work;

[0035] Among them, a rubber pad is fixedly provided on the top surface of the first push rod to enhance the extrusion force and prevent damage to the workpiece.

[0036] Furthermore, if Figure 5 As shown, the bottom of the second trough 110 is tilted downward in the direction away from the first trough 210, and the tilt angle is less than 2°; the bottom position corresponding to the material extraction port 140 and the first through hole 111 is flush with the horizontal plane, and has a smooth transition with the lower end of the tilt, providing a basic inclined sliding surface to facilitate the movement and arrangement of the workpieces toward the material extraction port.

[0037] Furthermore, if Figure 7 As shown, the material transfer device 600 includes a gripping structure 700 and a moving structure 800; the moving structure 800 is used to drive the gripping structure 700 to move horizontally and vertically on the horizontal plane, and adjust the position of the gripping structure on the material guide tray and the material discharge tray; the gripping structure is provided with a gripping component that can be lifted and lowered vertically, which is used to pick up and place the workpiece; it realizes movement in three directions, ensuring that the workpiece can be gripped and transferred.

[0038] Furthermore, if Figures 8 to 10As shown, the grabbing structure 700 includes a second cylinder 710, a support frame 720, an air collecting box 730, and a second infrared sensor 740; the second cylinder 710 is installed on the moving part of the moving structure 800, and the support frame 720 is installed at the end of the piston rod of the second cylinder 710; the bottom of the support frame 720 is provided with a plurality of second through holes 721 evenly spaced along the length direction of the material trough, and the spacing distance of the second through holes is consistent with the center distance of the two connected workpieces; the bottom surface of the air collecting box 730 is connected and installed with a plurality of suction nozzles 731, and the air collecting box 730 is installed on the support frame 720. In the frame 720, the suction nozzle 731 passes through the second through-hole 721 and goes out of the bottom surface of the support frame. The air collecting box is connected to the external negative pressure equipment through the air supply hose, and serves as a grasping component to grasp the workpiece by suction. The number of the second infrared sensors 740 is 2, which are installed on the bottom of both sides of the support frame 720. The workpiece is negatively adsorbed by multiple suction nozzles, and multiple workpieces can be sucked at the same time, thereby improving the transportation and arrangement efficiency of the workpiece. The second infrared sensor is used for detection to prevent the transferred workpiece from colliding with the original workpiece in the material trough, thereby ensuring the normal transfer and arrangement of the workpiece.

[0039] Furthermore, the movable structure includes a first linear slide and two oppositely arranged second linear slides, the second linear slides extend along the width direction of the material guide tray, the two second linear slides are respectively arranged above the end positions of the material guide tray and the collection tray, the first linear slide is mounted between the sliders of the two second linear slides, and the first linear slide extends along the length direction of the material trough; the second cylinder is installed on the slider of the first linear slide, and is driven by the first linear slide and the second linear slide to achieve lateral and longitudinal movement, and combined with the extension and retraction of the second cylinder, the overall lateral movement and lifting activities of the grasping part are completely realized.

[0040] Furthermore, elastic clamping assemblies 750 are provided on the outer sides of both ends of the air collecting box 730; the elastic clamping assembly 750 includes a clamping member 751 and a first spring 752, the clamping member 751 includes a second push rod 7511, a guide rod 7512 fixedly arranged at the top end of the second push rod, and a limiting plate 753 is installed on the top of the guide rod 7512; third through holes 722 are provided at both ends of the bottom of the support frame 720, and the spacing between the third through hole and the adjacent second through hole is consistent with the spacing distance of the second through hole; the third through hole 722 is a rectangular hole structure, and the shape of the second push rod 7511 is The shape of the guide hole 723 matches the shape of the third through hole 722; the top of the support frame 720 is correspondingly provided with a guide hole 723, and the shape of the guide hole 723 matches the shape of the guide rod 7512; the pressing member 751 is penetrated at the third through hole 722 and the guide hole 723, the limiting plate 753 is located at the top outer side of the support frame 720, the first spring 752 is sleeved at the guide rod 7512, and the first spring 752 is clamped between the top of the support frame 720 and the second push rod 7511, providing the second push rod with an elastic force to push downward, so that the pressing member has space to move in the vertical direction;

[0041] The design of the elastic clamping component is mainly used to clamp the workpieces on the outside of the two ends of the suction nozzle to prevent the two workpieces from moving with the middle part being sucked or even falling out of the material trough; the elastic clamping component adopts the above structure, and before the suction nozzle presses against the workpiece, the clamping part will press against the top of the workpiece on both sides in advance, but will not affect the continued downward movement of the suction nozzle; and, when the suction nozzle grabs the workpiece and leaves the material trough, the clamping part still maintains pressure on the workpiece to prevent the workpieces on both sides from moving along with it.

[0042] Furthermore, a second spring 754 is sleeved on the guide rod 7512, and the second spring 754 is located between the limit plate 753 and the top surface of the support frame 720; a ring-shaped electromagnet 760 is arranged around the outer side of the top of the guide hole 723, and the second spring 754 is located at the inner ring of the electromagnet 760, the limit plate 753 is located above the electromagnet 760, and a magnet block 755 is fixedly arranged on the bottom surface of the limit plate 753; when the clamping member is not subjected to external force, the bottom end of the second push rod is not higher than the bottom end of the suction nozzle, and a gap of at least the thickness of the workpiece is left between the magnet block and the electromagnet; the magnetism of the electromagnet after power-on is opposite to that of the magnet block, and the magnetic attraction force is used to overcome the elastic force of the second spring to move the clamping member downward; this structural design can make the clamping member have the effect of adjusting the extension separately, and the second push rod extending outward can be used as the part for pushing the workpiece, and the workpiece can be pushed in conjunction with the moving structure, so that the workpiece can be pushed to the target position, and the scattered workpieces can also be arranged closely to facilitate the overall arrangement.

[0043] It should be noted that the pressing member, the limit plate, the magnet block, the first spring and the second spring are in a state of force balance when the electromagnet is not powered, and the pressing member has room for movement to rise and fall, meeting the corresponding action requirements;

[0044] Furthermore, a threaded rod is fixedly provided at the top of the guide rod, a fourth through hole is provided in the middle of the limit plate, a nut is fixedly provided at the outer side of the top of the fourth through hole, and the limit plate is fixed to the threaded rod through the nut thread connection, and a detachable structure is adopted, which is convenient for the processing and production of various structural components, and also convenient for the assembly of the elastic clamping assembly and the support frame;

[0045] Furthermore, it also includes an electric control box, and the electrical structures of the present invention, the external transfer equipment, the pad printing equipment, and the negative pressure equipment are all electrically connected to the electric control box, and the coordinated movement of the structures is achieved through the electric control box to prevent interference and collision problems and maintain the smooth operation of the whole. It should be noted that the vibration loading tray, industrial camera, linear slide, cylinder, infrared sensor, and alarm are all common mechanical structures that can be purchased and used on the market, and the specific structure is not described in detail;

[0046] More specifically, the operation steps are as follows: the vibrating loading tray loads materials through vibration, so that the workpieces are arranged and transported to the first material trough, and then transferred to the corresponding second material trough through the first material trough, and the workpieces are arranged along the inclined surface to the bottom; the industrial camera shoots the guide tray and the discharge tray to feedback the arrangement of the workpieces; when a second material trough is obviously lacking in workpieces, the material transfer device grabs the workpiece from the first material trough or the second material trough corresponding to the first material trough and transfers it to the required position to realize the diversion and arrangement of the workpieces;

[0047] Furthermore, when putting down the workpiece, it is necessary to first move to the upper side of the corresponding material trough close to the end of the material guide tray under the drive of the second linear slide, and then the first linear slide drives the grasping structure to move along the downstream direction of the material trough. When the second infrared sensor on the downstream side detects that there is a workpiece below, the material trough part corresponding to the suction nozzle is vacant at this time, and the second cylinder drives the workpiece to move down to a preset position, and the external negative pressure device releases pressure, and the workpiece moves from the suction nozzle to the material trough; then, the second cylinder drives the support frame to move up to a preset height, and the electromagnet on the upstream side is energized at this time, so that the second push rod at this part is maintained at the material trough, and then the support frame is driven to move downstream by the first linear slide, and the workpiece is pushed downstream, so that the workpiece moves to fill the corresponding vacant part below the second push rod part, so that the workpieces are closely arranged;

[0048] It should be pointed out that in actual use, since the vibration of the vibrating loading tray will be transmitted to other parts, although there is an inclined surface, it is impossible to prevent some workpieces from moving back, and the workpieces will appear loose and not arranged tightly. In this case, the electromagnet close to the downstream can be energized to make the corresponding second push rod extend downward alone. As a pushing component, with the cooperation of the second cylinder and the moving structure, the loosely arranged workpieces are pushed to be arranged as tightly as possible to the bottom, so as to facilitate the subsequent shooting and identification of the workpiece arrangement and determine whether refilling is needed.

[0049] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
