Description

Technical Field

[0001] This application relates to the technical field of circuit board manufacturing, and in particular to an SMT material rack cart for transportation. Background Technology

[0002] With the continuous development of technology, electronic products are becoming increasingly important in people's lives. Surface Mount Technology (SMT), a commonly used electronic manufacturing technology, is widely applied in the production of electronic products. SMT technology is a circuit assembly technology that mounts leadless or short-lead surface mount components onto the surface of printed circuit boards or other substrates, and then assembles them through reflow soldering or dip soldering. In today's world, where automated board loading and unloading machines are increasingly valued by various industries, SMT material carts help with the circulation, storage, and integrated management of PCB boards, making them essential for modern production management in manufacturing and outsourced processing companies.

[0003] Regarding the aforementioned technologies, the inventors believe that the shelves on existing SMT storage carts are mostly welded to the cart body, and the distance between each shelf is fixed. However, in actual use, the sizes of materials vary, and the distance between each shelf cannot be adjusted according to the size of the materials, thus limiting its use. Utility Model Content

[0004] To broaden the applicability of material rack carts, this application provides an SMT material rack cart for transportation.

[0005] The SMT material rack cart for transportation provided in this application adopts the following technical solution:

[0006] An SMT material rack cart for transportation includes a movable frame and a support assembly. The movable frame includes two vertically and parallelly arranged support frames, and a plurality of connecting rods are arranged parallel between the two support frames. The support assembly is disposed on the movable frame and includes two parallelly arranged shelf plates. The shelf plates are slidably connected to the plurality of connecting rods. A plurality of support plates are horizontally arranged on the side of the two shelf plates that are close to each other. A positioning assembly for connection is provided between the two shelf plates.

[0007] By adopting the above technical solution, the spacing between the two shelf plates is adjusted to match the width of the circuit boards of different specifications, and the spacing between the two shelf plates is fixed using positioning components. The circuit boards are then inserted sequentially into their corresponding two support plates, thus achieving circuit board storage. Through the cooperation of the movable frame and the support components, circuit boards of different specifications can be stored, thereby improving the applicability of the material rack cart.

[0008] Optionally, the positioning assembly includes a positioning sleeve, a positioning slide rod, and a positioning bolt. The positioning sleeve is vertically connected to one of the shelf plates, and the positioning slide rod is vertically connected to the other shelf plate. One end of the positioning slide rod is slidably disposed in the positioning sleeve, and the positioning bolt is threadedly connected to the positioning sleeve. The end of the positioning bolt extends into the positioning sleeve and abuts against the positioning slide rod.

[0009] By adopting the above technical solution, the distance between the two shelf plates on the connecting rod is adjusted for circuit boards of different widths, and the positioning slide rod slides in the positioning sleeve rod. When the two shelf plates are adjusted to a suitable distance, the positioning bolt is tightened, and the positioning bolt presses against the positioning slide rod, thereby limiting the position of the distance between the two shelf plates.

[0010] Optionally, the positioning slide bar is provided with scale lines along its length.

[0011] By adopting the above technical solution, the setting of the scale lines makes it easier for operators to accurately adjust the spacing between the two shelf boards according to the width of the circuit board.

[0012] Optionally, the shelf panels are vertically connected to each other along their centerline on the side that is close to each other, and the support plates are horizontally arranged on both sides of the opposite spacers.

[0013] By adopting the above technical solution, the space between two shelf panels is divided into two opposing storage spaces by the setting of the spacer bar. Operators can place circuit boards from opposite sides of the shelf panels, which increases the single storage capacity of the device.

[0014] Optionally, the shelf plate is provided with a plurality of connecting sliders, each connecting slider having a sliding groove. The plurality of connecting sliders are arranged one-to-one with the plurality of connecting rods and are slidably connected through the sliding grooves. An abutting roller is rotatably arranged on the inner wall of the sliding groove, and the abutting roller is rolled and fitted with the connecting rod.

[0015] By adopting the above technical solution, the connecting slider enables a sliding fit between the shelf panel and the connecting rod. The abutment roller reduces the sliding friction between the connecting slider and the connecting rod, making it easier for the operator to slide the shelf panel on the connecting rod.

[0016] Optionally, the connecting slider is provided with a fixing component, which includes a fixing plate and a fixing screw. The fixing plate is slidably disposed in the sliding groove, and the fixing screw is threadedly connected to the connecting slider. One end of the fixing screw extends into the sliding groove and is rotatably connected to the fixing plate.

[0017] By adopting the above technical solution, the shelf plate is adjusted to a suitable position on the connecting rod, and the fixing screw is tightened. The fixing plate moves closer to the connecting rod under the drive of the fixing screw and abuts against the connecting rod, thereby limiting the position of the shelf plate, reducing the possibility of the shelf plate sliding relative to the connecting rod when pushing the material rack, and improving the overall stability of the device.

[0018] Optionally, anti-detachment rotating plates are rotatably connected to the two opposite vertical sides of the shelf plate via connecting hinges. Anti-detachment torsion springs are provided on the connecting hinges. One end of the anti-detachment torsion spring is connected to the shelf plate, and the other end is connected to the anti-detachment rotating plate. In a natural state, the anti-detachment rotating plate rotates under the action of the anti-detachment torsion spring until it abuts against one end of the support plate.

[0019] By adopting the above technical solution, the anti-detachment rotating plate and the anti-detachment torsion spring limit the circuit board located between the two shelf plates, reducing the possibility of the circuit board falling between the shelf plates during the movement of the material rack trolley.

[0020] Optionally, one end of the connecting rod is provided with a connecting screw, which passes through the corresponding support frame and is threaded with a locking nut.

[0021] By adopting the above technical solution, the setting of connecting screw and locking nut realizes the detachable connection between connecting rod and support frame. When it is necessary to transfer and unload circuit boards as a whole, the support frame and connecting rod are separated, and the two shelf boards and several circuit boards set between them are slid off the connecting rod to unload the unloading rack, thus realizing the overall unloading of circuit boards.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Through the cooperation of the movable frame and the supporting components, the storage of circuit boards of different specifications is realized, which improves the applicability of the material rack cart;

[0024] 2. The fixed components reduce the possibility of the shelf plates sliding relative to the connecting rods when the material rack trolley is pushed, thus improving the overall stability of the device;

[0025] 3. The scale lines make it easy for operators to precisely adjust the spacing between the two shelf boards according to the width of the circuit board. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be further described in detail below. Embodiments of this application provide an SMT material rack cart for transportation, which improves the applicability of the material rack cart.

[0031] Reference Figure 1-3 An SMT material rack cart for transportation includes a movable frame 1, a support assembly 2, a fixing assembly 3, and a positioning assembly 4. The movable frame 1 includes two vertically and parallelly arranged support frames 101, and four connecting rods 102 are arranged parallel between the two support frames 101. The bottom end of the support frame 101 is provided with a movable roller 5, and one end of the connecting rod 102 is provided with a connecting screw 103. The connecting screw 103 passes through the corresponding support frame 101 and is threadedly connected to a locking nut 104.

[0032] Reference Figure 1 and Figure 2 The support assembly 2 is provided on the movable frame 1 in several sets. The support assembly 2 includes shelf plates 21, support plates 22, spacer bars 23, anti-detachment rotating plates 24, connecting hinges 25, anti-detachment torsion springs 26, connecting sliders 27, and abutment rollers 28. Two shelf plates 21 are arranged vertically and parallel to each other. Several connecting sliders 27 are connected to each shelf plate 21, and several connecting sliders 27 are arranged in a one-to-one correspondence with several connecting rods 102. The connecting sliders 27 are provided with sliding grooves 271, and the connecting sliders 27 are slidably connected to the connecting rods 102 through the sliding grooves 271. The connecting rods 102 are square rods, and the abutment rollers 28 are rotatably disposed on the inner wall of the sliding grooves 271, and the abutment rollers 28 are rolled and fitted against the side wall of the connecting rods 102.

[0033] Reference Figure 1 and Figure 2In the same set of support components 2, one spacer bar 23 is vertically installed at the center line position on the side where the two shelf plates 21 are close to each other. Several support plates 22 are horizontally installed on the side where the two shelf plates 21 are close to each other. One anti-detachment rotating plate 24 is rotatably installed on both sides of the shelf plate 21 in the width direction via a connecting hinge 25. An anti-detachment torsion spring 26 is installed on the connecting hinge 25, with one end of the anti-detachment torsion spring 26 connected to the anti-detachment rotating plate 24 and the other end connected to the shelf plate 21. In the natural state, the anti-detachment rotating plate 24 rotates under the action of the anti-detachment torsion spring 26 until it is in contact with one end of the support plate 22.

[0034] Reference Figure 1 and Figure 3 The positioning component 4 is disposed between two shelf plates 21 in the same set of support components 2. The positioning component 4 includes a positioning sleeve 41, a positioning slide rod 42, and a positioning bolt 43. The positioning sleeve 41 is vertically connected to one of the shelf plates 21, and the positioning slide rod 42 is vertically connected to the other shelf plate 21. One end of the positioning slide rod 42 is slidably disposed in the positioning sleeve 41, and a scale line 44 is provided on the positioning slide rod 42 along its length. The positioning bolt 43 is threadedly connected to the positioning sleeve 41, and the end of the positioning bolt 43 extends into the positioning sleeve 41 and abuts against the positioning slide rod 42.

[0035] Reference Figure 1 and Figure 2 The fixing component 3 is disposed on the connecting slider 27, and the fixing component 3 includes a fixing screw 31 and a fixing plate 32. The fixing plate 32 is slidably disposed in the sliding groove 271, the fixing screw 31 is threadedly connected to the connecting slider 27, and one end of the connecting slider 27 extends into the sliding groove 271 and is slidably connected to the fixing plate 32.

[0036] Reference Figure 1-3 Before using the material rack cart, adjust the distance between the two corresponding shelf plates 21. The setting of the abutment roller 28 reduces the sliding friction between the connecting rod 102 and the connecting slider 27, making it easier for the operator to move the shelf plate 21 along the length of the connecting rod 102. The distance between the two shelf plates 21 is precisely adjusted according to the scale line 44 on the positioning slide rod 42. After the precise adjustment of the distance is completed, tighten the positioning bolt 43. The positioning bolt 43 limits the position of the positioning slide rod 42, thus fixing the distance between the two shelf plates 21.

[0037] Reference Figure 1 and Figure 2The two anti-detachment rotating plates 24 are rotated away from the support plate 22, and the anti-detachment torsion spring 26 accumulates elastic potential energy. Several circuit boards are then inserted into the two corresponding support plates 22 in sequence. After the circuit boards are inserted, the anti-detachment rotating plates 24 are released, and the anti-detachment rotating plates 24 are reset under the action of the anti-detachment torsion spring 26, reducing the possibility of the circuit boards falling off the support plates 22 during movement. The spacer rod 23 divides the two shelf plates 21 into two storage spaces, increasing the storage capacity of the device. The two shelf plates 21 are moved to a suitable position on the connecting rod 102, and the fixing screw 31 is tightened. The fixing plate 32 moves to abut against the side wall of the connecting rod 102, which limits the position of the support assembly 2 on the connecting rod 102, reduces the possibility of the support assembly 2 shaking on the connecting rod 102 during the movement of the material rack, and improves the overall stability of the device.

[0038] Reference Figure 1 and Figure 3 When it is necessary to cut the circuit board as a whole, the locking nut 104 is removed from the connecting screw 103, the corresponding support frame 101 is separated from the connecting rod 102, and the supporting component 2 is slid off the connecting rod 102 as a whole, thus realizing the overall cutting of the circuit board.

[0039] The implementation principle of an SMT material rack cart for transportation in this embodiment is as follows: Before using the material rack cart, adjust the spacing between two corresponding shelf plates 21. Rotate the two anti-detachment rotating plates 24 away from the support plate 22, and insert several circuit boards sequentially onto the two corresponding support plates 22. Release the anti-detachment rotating plates 24, and the anti-detachment rotating plates 24 will reset under the action of the anti-detachment torsion spring 26. When it is necessary to unload the circuit board as a whole, remove the locking nut 104 from the connecting screw 103, separate the corresponding support frame 101 from the connecting rod 102, and slide the entire support assembly 2 off the connecting rod 102, thus realizing the overall unloading of the circuit board.

[0040] 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.
