Description

Technical Field

[0001] This application relates to the field of circuit board storage racks, and more particularly to a chip mounter storage module. Background Technology

[0002] Fully automatic placement machines are used to achieve high-speed, high-precision, and fully automated placement of electronic components. They are the most critical and complex equipment in the entire SMT production process. Placement machines are the main equipment in the SMT production line. They have evolved from early low-speed mechanical placement machines to high-speed optical alignment placement machines, and are developing towards multi-functionality, flexible connection, and modular design.

[0003] In existing technologies, common chip mounters all include a discharge conveyor belt. After the circuit board has been mounted, it is conveyed out by the conveyor belt. After the circuit board is delivered, it usually needs to be removed from the conveyor belt by the operator and stored in a storage rack. After the circuit board is completely removed, the operator needs to transfer the storage rack to a trolley for further transfer.

[0004] However, the common storage racks are in fixed positions, which often makes it difficult to place circuit boards in higher storage openings, and it is also difficult to manually transfer the storage racks to the trolley. There is room for improvement. Utility Model Content

[0005] To improve the convenience for operators in storing circuit boards and transferring storage racks, this application provides a chip mounter storage module.

[0006] The pick-and-place machine material storage module provided in this application adopts the following technical solution:

[0007] A chip mounter storage module includes a trolley, a storage rack, and two supports. The storage rack is detachably mounted on the trolley. Two sets of rollers are rotatably mounted on the bottom of the trolley. The two supports are arranged in parallel, and a space is formed between the two supports for the trolley and the storage rack to slide in or out.

[0008] The inner sides of the two brackets are equipped with a lifting drive mechanism for driving the storage rack to move up and down, and the drive end of the lifting drive mechanism is detachably connected to the storage rack.

[0009] By adopting the above technical solution, before processing circuit boards using the pick-and-place machine, the operator can install the storage rack on the trolley, push the trolley to place the storage rack between two supports, and adjust the position of the storage rack through the lifting drive mechanism to raise it to its highest point. After the circuit board that has completed the pick-and-place process is conveyed out by the conveyor belt, the operator removes the circuit board and places it on the storage rack. During the placement of the circuit board, the operator can gradually lower the height of the storage rack through the lifting adjustment mechanism to facilitate the placement of the circuit board. When the circuit board is stored, the operator can drive the storage rack to its lowest height through the lifting mechanism, so that the storage rack is placed back on the trolley. The operator can then push out the trolley to conveniently transfer the storage rack, eliminating the need to manually move the storage rack to the trolley.

[0010] Preferably, the storage rack includes two first support rods and two second support rods, with the first support rods and the second support rods facing each other.

[0011] A plurality of first carriers are fixedly connected to the inner sidewalls of the two first support rods, and a plurality of second carriers are fixedly connected to the inner sidewalls of the two second support rods. The first carriers and the second carriers are opposite each other, and a placement groove for placing circuit boards is formed between the first carriers and the second carriers.

[0012] By adopting the above technical solution, and by setting up the first carrier and the second carrier, multiple layers of placement slots for placing circuit boards can be formed on the storage rack.

[0013] Preferably, a hand handle is fixedly connected to the top of the trolley, and baffles are fixedly connected to the inner side walls of the first and second support rods near the hand handle, with the two baffles respectively covering the ends of the first and second carrier frames.

[0014] By adopting the above technical solution, the end of the circuit board that extends into the placement groove can be blocked and limited by the setting of the baffle.

[0015] Preferably, the storage rack includes a top plate and a bottom plate, and the two ends of the first support rod and the second support rod are fixedly connected to the top plate and the bottom plate, respectively;

[0016] The top plate has a through hole, and a positioning rod is detachably installed in the through hole. A sleeve is fixedly connected to the top of the bottom plate. The sleeve is located directly below the through hole. The bottom end of the positioning rod passes through the through hole and extends into the sleeve. The positioning rod is positioned on the side of the circuit board away from the baffle.

[0017] By adopting the above technical solution, and by setting the positioning rod, when the storage rack is equipped with circuit boards and the operator needs to transfer the storage rack by trolley, the positioning rod can be inserted into the socket and the end of the positioning rod can be inserted into the sleeve. This can position the side of the circuit board on the storage rack away from the baffle, preventing the circuit board from shifting or falling off during the transfer process.

[0018] Preferably, the bottom of the base plate is fixedly connected with a number of limiting posts, and the top of the trolley is provided with a number of limiting holes that are adapted to the limiting posts. The limiting posts are detachably installed in the limiting holes.

[0019] By adopting the above technical solution, the limiting post extends into the limiting hole, which can limit the bottom of the storage rack in four directions: front, back, left, and right, thus achieving the technical effect of detachable connection between the storage rack and the trolley.

[0020] Preferably, the lifting drive mechanism includes two motors and two lead screws, and each bracket includes a first mounting plate and a second mounting plate. The first mounting plate is mounted above the second mounting plate, and the upper and lower ends of the lead screws are rotatably mounted on the first mounting plate and the second mounting plate, respectively.

[0021] The cylinder of the servo motor is fixedly installed at the bottom of the second mounting plate. The drive shaft of the servo motor is connected to the lead screw through a coupling. A slide is threaded on the lead screw. A lifting plate is fixedly connected to the bottom of each slide. Both lifting plates are located inside the bracket. The base plate is detachably installed on the top of the two lifting plates.

[0022] Guide rods are fixedly connected between the first mounting plate and the second mounting plate, and through holes for the guide rods are opened on the lifting plates.

[0023] By adopting the above technical solution, after the operator moves the trolley between the two supports, the base plate of the storage rack can be placed above the two lifting plates. The servo motor drives the lead screw to rotate, which in turn drives the two lifting plates and the storage rack to rise as a whole via the slide table. During the placement of the circuit board, the operator can control the servo motor to reverse the lead screw according to their own needs, which in turn drives the lifting plates and the storage rack to move down via the slide table. The two guide rods restrict the sliding trajectory of the two lifting plates, improving the ease of raising and lowering the lifting plates and the storage rack.

[0024] Preferably, the top of the trolley is fixedly connected with a first positioning plate and a second positioning plate, and the first positioning plate and the second positioning plate cover the front and rear sides of the storage rack.

[0025] By adopting the above technical solution, the first positioning plate covers the front and rear sides of the storage rack, which can further improve the stability of the storage rack.

[0026] Preferably, a third positioning plate is fixedly connected to the side of the two brackets away from the hand grip, and the third positioning plate limits and blocks the side of the first positioning plate away from the hand grip.

[0027] By adopting the above technical solution and setting a third positioning plate between the two supports, when the operator pushes the trolley between the two supports and makes the first positioning plate abut against the third positioning plate, the two lifting plates can be positioned in the middle of the bottom plate of the storage rack, which can improve the convenience of the operator to adjust the position of the trolley and the storage rack.

[0028] In summary, the chip mounter material storage module of this application has at least the following beneficial technical effects:

[0029] 1. After the circuit board that has completed the surface mount process is sent out by the conveyor belt, the operator removes the circuit board and places it on the storage rack. During the process of placing the circuit board, the operator can gradually lower the height of the storage rack through the lifting adjustment mechanism to facilitate the placement of the circuit board.

[0030] 2. After the circuit boards are stored, the operator can use the lifting mechanism to drive the storage rack down to the lowest height, so that the storage rack can be placed back on the trolley. The operator can then push out the trolley to easily transfer the storage rack, eliminating the need to manually move the storage rack onto the trolley. Attached Figure Description

[0035] The following combination Figures 1-3This application will be described in further detail.

[0036] Example

[0037] This application discloses a material storage module for a chip mounter. (Refer to...) Figure 1 It mainly includes a trolley 1, a storage rack 2, and two supports 3. The two supports 3 are fixed to the port of the discharge conveyor belt of the chip mounter with screws. The storage rack 2 is detachably installed on the trolley 1. Two sets of rollers 11 are rotatably installed on the bottom of the trolley 1. The two supports 3 are arranged parallel to each other on the left and right sides of the trolley 1 and the storage rack 2, and a space is formed between the two supports 3 for the trolley 1 and the storage rack 2 to slide in or out. The inner side of the two supports 3 is equipped with a lifting drive mechanism 4 for driving the storage rack 2 to move up and down. The drive end of the lifting drive mechanism 4 is detachably connected to the storage rack 2.

[0038] Before using the pick-and-place machine to process the circuit board, the operator can install the storage rack 2 on the trolley 1, push the trolley 1 to place the storage rack 2 between the two supports 3, and adjust the position of the storage rack 2 through the lifting drive mechanism 4 to raise the storage rack 2 to its highest position. After the circuit board that has completed the pick-and-place process is sent out by the conveyor belt, the operator removes the circuit board and places it on the storage rack 2. During the placement of the circuit board, the operator can gradually lower the height of the storage rack 2 through the lifting adjustment mechanism to facilitate the placement of the circuit board. After the circuit board is stored, the operator can drive the storage rack 2 to its lowest height through the lifting mechanism to place the storage rack 2 back on the trolley 1. The operator can then push out the trolley 1 to easily transfer the storage rack 2 through the trolley 1, eliminating the need to manually move the storage rack 2 to the trolley 1.

[0039] Reference Figure 1 and Figure 2 The storage rack 2 includes two first support rods 21 and two second support rods 22. The two first support rods 21 and two second support rods 22 are located at the four corners of the storage rack 2, with the first support rods 21 and the second support rods 22 facing each other. A plurality of first carriers 23 are fixedly connected to the inner sidewalls of the two first support rods 21, and a plurality of second carriers 24 are fixedly connected to the inner sidewalls of the two second support rods 22. The first carriers 23 and the second carriers 24 face each other, and a placement groove for placing circuit boards is formed between the first carriers 23 and the second carriers 24.

[0040] By setting up the first carrier 23 and the second carrier 24, multiple layers of placement slots for placing circuit boards can be formed on the storage rack 2.

[0041] Reference Figure 2A hand handle 12 is fixedly connected to the top of the trolley 1. Baffles 25 are fixedly connected to the inner side walls of the first support rod 21 and the second support rod 22 near the hand handle 12. The two baffles 25 respectively cover the ends of the first carrier 23 and the second carrier 24.

[0042] The baffle 25 can be used to block and limit the end of the circuit board that extends into the placement slot.

[0043] The storage rack 2 includes a top plate 26 and a bottom plate 27. The two ends of the first support rod 21 and the second support rod 22 are fixedly connected to the top plate 26 and the bottom plate 27, respectively. A through hole is provided on the top plate 26, and a positioning rod 261 is detachably installed in the through hole. The positioning rod 261 is located on the side of the storage rack 2 away from the hand handle 12. A sleeve 271 is fixedly connected to the top of the bottom plate 27. The sleeve 271 is located directly below the through hole. The bottom end of the positioning rod 261 passes through the through hole and extends into the sleeve 271. The positioning rod 261 is limited and set on the side of the circuit board away from the baffle 25.

[0044] With the positioning rod 261 in place, when the storage rack 2 contains circuit boards and the operator needs to move the storage rack 2 using the trolley 1, the positioning rod 261 can be inserted into the socket, with its end extending into the sleeve 271. This positions the side of the circuit board on the storage rack 2 away from the baffle 25, preventing the circuit board from shifting or falling off during the transfer process. When it is necessary to remove the circuit board from the storage rack 2, the operator can remove the positioning rod 261 from the socket.

[0045] Reference Figure 3 The bottom of the base plate 27 is fixedly connected with several limiting posts 272, and the top of the trolley 1 is provided with several limiting holes that are adapted to the limiting posts 272. The limiting posts 272 are detachably installed in the limiting holes. The limiting posts 272 extend into the limiting holes, which can limit the bottom of the storage rack 2 in four directions: front, back, left, and right, so as to achieve the technical effect of detachable connection between the storage rack 2 and the trolley 1.

[0046] Reference Figure 1The lifting drive mechanism 4 includes two motors and two lead screws 42. The bracket 3 includes a first mounting plate 31 and a second mounting plate 32. The first mounting plate 31 is mounted on the second mounting plate 32. The upper and lower ends of the lead screws 42 are rotatably mounted on the first mounting plate 31 and the second mounting plate 32, respectively. The cylinder of the servo motor 41 is fixedly mounted on the bottom of the second mounting plate 32. The drive shaft of the servo motor 41 is connected to the lead screw 42 through a coupling. A slide table 43 is threaded on the lead screw 42. The bottom of the slide table 43 is fixedly connected to a lifting plate 44. The two lifting plates 44 are located inside the bracket 3. The base plate 27 is detachably mounted on the top of the two lifting plates 44. A guide rod 33 is fixedly connected between the first mounting plate 31 and the second mounting plate 32. The lifting plate 44 is provided with a through hole for the guide rod 33 to pass through.

[0047] After the operator moves the trolley 1 between the two supports 3, the base plate 27 of the storage rack 2 can be placed above the two lifting plates 44. The servo motor 41 drives the lead screw 42 to rotate, which in turn drives the two lifting plates 44 and the storage rack 2 to rise as a whole via the slide table 43. During the placement of the circuit board, the operator can control the servo motor 41 to drive the lead screw 42 to reverse according to their own needs, which in turn drives the lifting plates 44 and the storage rack 2 to move down via the slide table 43. The two guide rods 33 can restrict the sliding trajectory of the two lifting plates 44, improving the ease of raising and lowering the lifting plates 44 and the storage rack 2.

[0048] In this embodiment, an up control button and a down control button are fixedly installed on the top of the bracket near the second support rod. The signal output terminals of the up control button and the down control button are connected to a microcontroller. The signal output terminal of the microcontroller is connected to the signal input terminal of the servo motor. The operator can continuously press the up control button or the down control button according to the actual use needs. After the microcontroller recognizes the input signal, it controls the servo motor to drive the slide table in a clockwise or counterclockwise direction, so as to achieve the technical effect of driving the slide table, the lifting plate, and the storage rack to move up and down.

[0049] Reference Figure 1 and Figure 3 The top of the trolley 1 is fixedly connected to a first positioning plate 13 and a second positioning plate 14, which cover the front and rear sides of the storage rack 2. The first positioning plate 13 covers the front and rear sides of the storage rack 2, which can further improve the stability of the storage rack 2.

[0050] Reference Figure 3 Two brackets 3 are fixedly connected to a third positioning plate 34 on the side away from the hand grip 12. The third positioning plate 34 limits and blocks the side of the first positioning plate 13 away from the hand grip 12.

[0051] By setting the third positioning plate 34 between the two supports 3, when the operator pushes the trolley 1 between the two supports 3 and makes the first positioning plate 13 abut against the third positioning plate 34, the two lifting plates 44 can be positioned in the middle of the bottom plate 27 of the storage rack 2, which can improve the convenience of the operator to adjust the position of the trolley 1 and the storage rack 2.

[0052] It should be noted that in some other embodiments, in order to increase the stability of the connection between the lifting plate 44 and the base plate 27, limiting grooves adapted to the lifting plate 44 can be opened on both sides of the bottom of the base plate 27.

[0053] The implementation principle of a chip mounter storage module in this application embodiment is as follows: After the operator moves the trolley 1 between the two supports 3, the base plate 27 of the storage rack 2 can be placed above the two lifting plates 44. The servo motor 41 drives the lead screw 42 to rotate, which drives the two lifting plates 44 and the storage rack 2 to rise as a whole through the slide table 43. During the placement of the circuit board, the operator can control the servo motor 41 to drive the lead screw 42 to reverse according to their own needs, which drives the lifting plates 44 and the storage rack 2 to move down through the slide table 43. By setting two guide rods 33, the sliding trajectory of the two lifting plates 44 can be restricted respectively, improving the convenience of lifting the lifting plates 44 and the storage rack 2 up and down.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
