Description

Technical Field

[0001] The present invention relates to the technical field of SMT tray storage, and in particular to an intelligent material rack for storing and retrieving SMT trays. Background Art

[0002] SMT trays are widely used in various industries, including batteries, hardware, electronics, pharmaceuticals, food, and connectors. They are essential for feeding materials into industrial automation equipment and are available in various sizes, including 7-inch and 13-inch. In SMT factories, various types of electronic products require a wide variety of SMT trays, both in different models and standards. Therefore, they must be categorized and stored for easy access.

[0003] In the current SMT tray storage process, the traditional method is usually to use the storage rack form, and the staff will place the SMT trays one by one on the support plate of the rack. However, as the space on the rack gradually decreases, the staff needs to sort and guide the already placed SMT trays to accommodate more trays, resulting in overall low efficiency. At the same time, when the SMT trays are taken out, because the SMT trays are closely packed together, the distance between the SMT trays is small. As a result, the staff needs to stabilize the other trays first, leaving a gap before taking the tray out. The whole process is quite laborious. Therefore, the current SMT tray picking and placing is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0023] Finally, by setting up a distance sensor and a clamping and lifting component, when the SMT tray is placed, after the distance sensor senses the position of the SMT tray, the clamping and lifting component clamps the SMT tray laterally, further improving the stability during placement. At the same time, when taking out, the clamping and lifting component pushes out part of the SMT tray, further facilitating quick removal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0047] Example 1

[0048] Reference Figures 1-18 When the rack body 1 is initially placed, both sides of the rack body 1 are not close to the wall, that is, the SMT tray 5 can be taken out from the rack body 1 or a new SMT tray 5 can be placed in any direction as needed.

[0049] At this time, an intelligent material rack for storing and retrieving SMT material trays includes a material rack body 1 and several supporting and regulating frames 2 installed on the material rack body 1; the material rack body 1 is composed of horizontal beams and longitudinal beams, and the supporting and regulating frames 2 are vertically connected to the longitudinal beams, and the distance between adjacent supporting and regulating frames 2 is at least 1.5 times the height of the SMT material tray 5. The top surface of the supporting and regulating frame 2 is installed with several first material tray boxes 3 and second material tray boxes 4 arranged in an alternating manner. A self-locking driving component 12 is provided inside the supporting and regulating frame 2 for driving several first material tray boxes 3 and several second material tray boxes 4 to move synchronously in the opposite direction. Driven by the self-locking driving component 12, several first material tray boxes 3 and several second material tray boxes 4 move in opposite directions and have the same moving distance. Initially, the first material tray box 3 and the second material tray box 4 are both arranged in the middle of the supporting and regulating frame 2; each first material tray box 3 and the second material tray box 4 correspond to an SMT material tray 5, and both sides of the top surface of each first material tray box 3 and the second material tray box 4 are connected to a clamping block frame 6, which can block the SMT material tray 5, and a magnetic telescopic clamping member 7 that is magnetically attracted or magnetically repelled by the clamping block frame 6 is provided on the top of the clamping block frame 6; the magnetic telescopic clamping member 7 clamps the SMT material tray 5 laterally.

[0050] Each of the first tray box 3 and the second tray box 4 is symmetrically provided with a clamping and lifting assembly 11 for clamping or lifting the SMT tray 5, that is, the SMT tray 5 is clamped during storage and lifted up when it is taken out. When the SMT trays 5 are taken in and placed in the staggered first tray box 3 and the second tray box 4, the self-locking drive assembly 12 displaces the SMT trays 5 on the first tray box 3 and the second tray box 4 front and back, so that a gap is formed between adjacent SMT trays 5. At the same time, the clamping and lifting assembly 11 forms a vertical dislocation, so that a gap is formed between adjacent SMT trays 5, making it easier to take in and place. After the SMT trays 5 on the first tray box 3 are taken in and placed, they can be exchanged with the second tray box 4 so that the same position can be taken in and placed again.

[0051] The first tray box 3 and the second tray box 4 are described in detail below:

[0052] Reference Figures 1-9The first material tray box 3 and the second material tray box 4 have the same size and structure. The bottom surfaces of the first material tray box 3 and the second material tray box 4 are both equipped with a sliding bottom frame 8 that is slidably arranged on the bottom wall inside the support and control frame 2. Among them, the top surface of the sliding bottom frame 8 of the first material tray box 3 is equipped with an upper tooth plate 9, and the bottom surface of the sliding bottom frame 8 of the second material tray box 4 is equipped with a lower tooth plate 10. The upper end of the self-locking drive component 12 is engaged with the upper tooth plate 9, and the lower end is engaged with the lower tooth plate 10. The self-locking drive assembly 12 includes a transmission shaft 121 rotatably mounted in the middle of the supporting and regulating frame 2, a plurality of driving gears 122 mounted on the transmission shaft 121, a worm gear 123 mounted at the end of the transmission shaft 121, and a worm driving member 124 arranged at the end of the supporting and regulating frame 2 and connected to the worm gear 123. The worm driving member 124 includes a worm and a servo motor, which can make the worm gear 123 rotate forward and reverse. The plurality of driving gears 122 correspond to the first material tray box 3 and the second material tray box 4, respectively, and the transmission shaft 121 passes through the middle of the sliding bottom frame 8, wherein the top end of a part of the driving gears 122 is engaged with the upper tooth plate 9, and the bottom end of the other part of the driving gears 122 is engaged with the lower tooth plate 10.

[0053] Specifically, when driving the first material tray box 3 and the second material tray box 4 to stagger front and back, the worm drive 124 is first started, and the worm drive 124 drives the worm gear 123 to rotate. The worm gear 123 rotates, driving the transmission shaft 121 to rotate, and the transmission shaft 121 rotates to make several driving gears 122 rotate. The driving gear 122 rotates, meshes with the upper gear plate 9 to drive the first material tray box 3 to move forward, and meshes with the lower gear plate 10 to drive the second material tray box 4 to move backward. The front and back here are based on the position when the staff placed it as the front. After the first material tray box 3 and the second material tray box 4 move back and forth, they are staggered front and back to facilitate taking and placing. When the first material tray box 3 is taken and placed, the worm drive 124 works in the opposite direction. Similarly, the first material tray box 3 moves backward and the second material tray box 4 moves forward, so that the first material tray box 3 and the second material tray box 4 exchange positions.

[0054] To ensure stability when the first and second tray boxes 3 and 4 move back and forth, a notch 201 is centrally located on the top surface of the support and control frame 2. The bottom surfaces of the first and second tray boxes 3 and 4 are horizontally attached to the bottom wall of the notch 201, and the sides of the first and second tray boxes 3 and 4 are horizontally attached to the side walls of the notch 201, so that the first and second tray boxes 3 and 4 are parallel and in contact with each other. At the same time, the sliding bottom frame 8 is attached to the inner bottom wall of the support and control frame 2, thereby ensuring that all the first and second tray boxes 3 and 4 maintain stable horizontal movement when moving back and forth.

[0055] Furthermore, when the first tray box 3 and the second tray box 4 move back and forth to form a staggered state, so as to facilitate the taking and placing of the SMT tray 5, in order to make the SMT tray 5 more stable after being placed, and in the movement after the first tray box 3 and the second tray box 4 are placed, the state change of the movement is combined with the horizontal clamping state of the SMT tray 5, so that the clamping is done during the moving storage and is released during the moving removal. The above linkage state is described in detail below:

[0056] Reference Figures 1-12 A first energized bottom contact plate 202 is provided in the center of the inner bottom wall of the support and control frame 2, and a second energized bottom contact plate 203 is provided on one side of the first energized bottom contact plate 202. The second energized bottom contact plate 203 is located on the side where the worker takes and places the SMT material tray 5. The bottom surfaces of the first material tray box 3 and the second material tray box 4 are both provided with sliding energized contacts 801 that slide in contact with the energized bottom contact plate. Several sliding energized contacts 801 are arranged in parallel when they are in contact and connected with the first energized bottom contact plate 202 or the second energized bottom contact plate 203, and the current direction when the sliding energized contact 801 is in contact with the first energized bottom contact plate 202 is opposite to the current direction when the sliding energized contact 801 is in contact with the second energized bottom contact plate 203. The sliding energized contact 801 is connected to the magnetic telescopic clamping piece 7. The first powered bottom contact plate 202 or the second powered bottom contact plate 203 is respectively connected to two separate circuits, and in the two circuits, the current and voltage are the same, but the current direction is opposite, so that the current direction of the sliding powered contact piece 801 when connected to the two circuits is opposite, and thus the current of the circuit where the magnetic telescopic clamping piece 7 is located is opposite, and several magnetic telescopic clamping pieces 7 are arranged in parallel so that their states do not interfere with each other.

[0057] When the current directions of the magnetic telescopic clamping piece 7 are opposite when they are connected in two circuits, in order to better clamp or detach the SMT material tray 5, specifically, a magnetic block 601 is fixed to the top of one of the clamping frames 6 on both sides of the first material tray box 3 and the second material tray box 4, and the magnetic telescopic clamping piece 7 includes a fixed plug rod 71 fixedly installed on the top of one of the clamping frames 6 and a sliding plug rod 72 slidably installed on the top of the other clamping frame 6. The sliding plug rod 72 is installed at the clamping frame 6 where the magnetic block 601 is located, and the sliding plug rod 72 is located on the inner side of the two clamping frames 6. One end of the sliding plug rod 72 is connected to a buffer pad, and the other end is equipped with an electromagnet connected to the sliding power contact 801. When the electromagnet is energized, it attracts or repels the magnetic block 601. One end of the fixed plug rod 71 is used to block the SMT material tray 5 after it is placed, and the sliding plug rod 72 is used to block the sliding contact 801. When the energized contact piece 801 contacts the first energized bottom contact plate 202, the electromagnet at the end is attracted by the magnetic block 601, causing the sliding rod 72 to move toward the SMT tray 5 until the end of the sliding rod 72 with the buffer pad is pressed on the SMT tray 5, and finally the SMT tray 5 is laterally clamped between the fixed rod 71 and the sliding rod 72. When the sliding energized contact piece 801 contacts the second energized bottom contact plate 203, the electromagnet at the end of the sliding rod 72 and the magnetic block 601 repel each other, causing the sliding rod 72 to move away from the SMT tray 5 and no longer clamp the SMT tray 5, so as to facilitate the removal of the SMT tray 5. In addition, the coverage range of the second energized bottom contact plate 203 extends to the initial position when the first tray box 3 and the second tray box 4 are placed, so that the sliding rod 72 and the magnetic block 601 are already in a repulsive state when initially placed, thereby facilitating the initial placement of the SMT tray 5.

[0058] Working principle: Initially, the first tray box 3 and the second tray box 4 are in the middle position of the support and regulation frame 2. At this time, the sliding energized contact piece 801 contacts the first energized bottom contact plate 202, and the electromagnet on the sliding rod 72 and the magnetic block 601 attract each other, so that the sliding rod 72 moves in the direction of the SMT tray 5 to be placed. Then, the self-locking drive component 12 is started to move the first tray box 3 to the edge of the support and regulation frame 2, and the placement of the SMT tray 5 begins. At the same time, the sliding energized contact piece 801 contacts the second energized bottom contact plate 203, and the electromagnet on the sliding rod 72 and the magnetic block 601 repel each other, and the sliding rod 72 moves to the direction of the SMT tray 5 to be placed. Move away from the direction of the SMT tray 5 to be placed until the SMT tray 5 is placed on the first tray box 3, and start to exchange positions with the second tray box 4. At this time, after the sliding powered contact 801 of the first tray box 3 leaves the second powered bottom contact plate 203, the sliding insertion rod 72 moves in the direction of the SMT tray 5 after placement, and clamps the SMT tray 5 laterally until the second tray box 4 is also placed. The first tray box 3 and the second tray box 4 are again in the middle of the support and adjustment frame 2, and the sliding powered contact 801 is in contact with the first powered bottom contact plate 202, keeping the sliding insertion rod 72 clamping the SMT tray 5.

[0059] Specifically, the placement of the SMT tray 5 will be described in detail below:

[0060] Ginseng Figures 1-18 The first tray box 3 and the second tray box 4 have a tray placement cavity 301 at the upper end and a control cavity 302 at the lower end. The SMT tray 5 is placed in the tray placement cavity 301. The middle part of the tray placement cavity 301 is arc-shaped to facilitate the stability of the disc-shaped SMT tray 5 after placement. Similarly, if the SMT tray 5 is of other shapes, the tray placement cavity 301 is adjusted as needed, and an arc-shaped groove for the clamping and lifting component 11 to pass through is opened on the arc surface of the tray placement cavity 301. 304, rotating shafts 305 are symmetrically installed at both ends of the arc-shaped groove 304, and two automatic winding rods 303 are symmetrically installed in the regulating chamber 302. Each automatic winding rod 303 has a built-in motor to drive the rotation. The middle part of the clamping and lifting component 11 is rotatably installed on the outside of the rotating shaft 305, and the end of the clamping and lifting component 11 is wrapped around the automatic winding rod 303 through a connecting rope. When the automatic winding rod 303 rotates, the clamping and lifting component 11 is pulled to rotate around the rotating shaft 305 by the connecting rope.

[0061] Specifically, the clamping and lifting assembly 11 includes an arc-shaped rotating top rod 111 and a rotating clamping rod 112. The rotating top rod 111 and the rotating clamping rod 112 are arranged side by side. The middle parts of the rotating top rod 111 and the rotating clamping rod 112 are provided with a through hole 113 installed on the rotating shaft 305. The lower end of the rotating top rod 111 is coaxially arranged with the arc-shaped groove 304, which will not interfere with the placement of the SMT material tray 5. The upper end of the rotating top rod 111 extends into the regulating cavity 302 and is connected to the automatic winding rod 303, wherein the upper end of the rotating top rod 111 is provided with a top rod winding interface 11101 connected to the connecting rope, and the upper and lower ends of the rotating clamping rod 112 are both arranged in the regulating cavity 302, wherein the bottom end of the rotating clamping rod 112 is connected to the automatic winding rod 303, wherein the bottom end of the rotating clamping rod 112 is provided with a clamping rod winding interface 11201 connected to the connecting rope. When the automatic winding rod 303 rotates, the rotating clamping rod 112 is forced at the bottom end and the top extends into the tray placement cavity 301, and the rotating top rod 111 is forced at the top end and the bottom extends into the tray placement cavity 301.

[0062] More specifically, in order to make the force states of the rotating clamping rod 112 and the rotating top rod 111 different when the automatic winding rod 303 rotates forward and backward, the connecting ropes of the rotating clamping rod 112 and the rotating top rod 111 are wound around the same automatic winding rod 303 in opposite directions, and torsion springs are installed between the rotating clamping rod 112 and the rotating shaft 305, as well as between the rotating top rod 111 and the rotating shaft 305. That is, after the rotating clamping rod 112 and the rotating top rod 111 rotate around the rotating shaft 305 under force, when the force is no longer applied, the rotating clamping rod 112 and the rotating top rod 111 return to their original state under the action of the torsion springs. Figure 16 The clamping rod 112 and the push rod 111 are in the initial state.

[0063] In order to further realize the intelligence of the material rack, the rotating clamp rod 112 and the rotating top rod 111 are automatically adjusted according to the use status of the material rack, and a distance sensor 802 is introduced to detect the distance between the first material tray box 3 and the second material tray box 4 and one side of the support and control frame 2. The distance sensor 802 is installed on the side of the sliding bottom frame 8, so that the automatic winding rod 303 controls the rotating top rod 111 to lift the SMT material tray 5 or the rotating clamp rod 112 to clamp the SMT material tray 5. Specifically, an initial threshold R of the distance between the first material tray box 3 and the second material tray box 4 and one side of the support and control frame 2 is preset. When the detection distance H is greater than R, the first material tray box 3 and the second material tray box 4 are in the middle of the support and control frame 2 or on the side away from the pick-up and placement position. The automatic winding rod 303 rotates clockwise and pulls the bottom end of the rotating clamp rod 112 to rotate around the rotating shaft 305 through the connecting rope, so that the top end of the rotating clamp rod 112 clamps the SMT material tray 5 as shown in FIG. Figure 17As shown, when the detection distance H is less than or equal to R, the first tray box 3 and the second tray box 4 are on the side close to the pick-up and placement position, and the SMT tray 5 needs to be picked up and placed. The automatic reeling rod 303 rotates counterclockwise, the connecting rope connected to the rotating clamping rod 112 is loosened, and the rotating clamping rod 112 is restored under the torsion spring. At the same time, the top of the rotating ejector rod 111 is pulled downward, so that the bottom end of the rotating ejector rod 111 moves upward around the rotating shaft 305, and the SMT tray 5 is lifted up. Figure 18 As shown, it is convenient to take and place the SMT tray 5.

[0064] Example 2

[0065] Reference Figure 19-20 When the entire rack body 1 is placed against the wall, the rack body 1 is close to the wall and the SMT tray 5 can only be taken in and placed from one direction, that is, when the self-locking drive component 12 is working, only one of the first tray box 3 and the second tray box 4 can move.

[0066] At this time, in an intelligent material rack for storing and retrieving SMT material trays, the rest of the structure remains unchanged, and only the self-locking drive component 12 is changed. Specifically, the self-locking drive component 12 includes a transmission shaft 121 provided in the middle of the supporting and regulating frame 2, a plurality of driving gears 122 installed on the transmission shaft 121, and a screw drive 125 provided at the end of the supporting and regulating frame 2 and driving the transmission shaft 121 to move. The screw of the screw drive 125 passes through the end of the transmission shaft 121 and is adapted to the transmission shaft 121, so that when the screw motor is working, it can drive the transmission shaft 121 to move along the screw and drive the plurality of driving gears 122 to move. The self-locking drive component 12 also includes a plurality of tightening rods 126 installed at the incision 201, wherein the tightening rods 126 are simultaneously controlled by a cylinder on one side of the incision 201.

[0067] Working principle: When the end of the first tray box 3 needs to move the discharge rack body 1 to facilitate the removal of the SMT tray 5, the tightening clamping rod 126 that locks the second tray box 4 is started to rise, and the tightening clamping rod 126 is pushed into the inner side of the second tray box 4. After the second tray box 4 is locked, the screw driving member 125 drives the transmission shaft 121 to move forward together with the first tray box 3, driving the first tray box 3 to move the discharge rack body 1 forward, forming a misalignment between the first tray box 3 and the stationary second tray box 4, and then taking out the SMT tray 5 on the first tray box 3 or putting the SMT tray 5 into the first tray box 3;

[0068] When the end of the second tray box 4 needs to be moved out of the rack body 1 to facilitate the removal of the SMT tray 5, the tightening rod 126 that locks the first tray box 3 is started to rise, and the tightening rod 126 is pushed into the inner side of the first tray box 3. After the first tray box 3 is locked, the screw drive 125 drives the transmission shaft 121 to move backward together with the first tray box 3, driving the second tray box 4 to move forward to the unloading rack body 1, forming a misalignment between the second tray box 4 and the stationary first tray box 3, and then taking out the SMT tray 5 on the second tray box 4 or placing the SMT tray 5 into the second tray box 4.

[0069] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
