Technical Field

[0001] This invention relates to the field of electronic assembly technology, and more specifically to a tray carrier suitable for bulk components. Background Technology

[0002] With the development of the electronics industry, electronic products are becoming increasingly smaller, more diverse, and more complex. The circuits of these products are becoming more intricate and their integration levels are increasing, objectively placing higher demands on soldering equipment and assembly efficiency. Among these, the pick-and-place machine is responsible for the crucial tasks of picking up, inspecting, and placing electronic components. It is the most technologically advanced equipment in the SMT production line, greatly solving problems such as unstable solder joint quality, low efficiency, and low work quality associated with manual soldering, and is widely used in various industries and fields.

[0003] However, for some small-batch or R&D products using surface mount loose components, existing pick-and-place machine trays require specially customized carriers for loose components. Furthermore, each type of component must be placed separately, resulting in inconsistent standard specifications for the loose component feeders, limiting the number of components that can be placed, and leading to significant time spent on programming and component placement. While there are cases in the industry where components are re-taped for placement, this method requires custom-made tapes, incurring additional costs and workload, and significantly limiting actual placement efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a tray carrier suitable for bulk components, compatible with the simultaneous mounting of various types of bulk components.

[0005] The pallet carrier includes a rectangular metal frame and a long carrier;

[0006] The rectangular metal frame has a rectangular through hole in the middle, and a mounting platform is provided on the four side walls of the rectangular through hole, namely the upper, lower, left and right side walls. Multiple upper slots are provided on the mounting platform on the upper side wall, and multiple lower slots are provided on the mounting platform on the lower side wall. An upper slot and a lower slot facing each other form a pair of snap-fit ​​structures.

[0007] The long strip carrier is placed on the rectangular through hole and contacts the mounting platform; the upper end and the lower end of the long strip carrier respectively have an upper locking block and a lower locking block protruding, and the upper locking block and the lower locking block respectively engage with the upper locking slot and the lower locking slot of a set of locking structures;

[0008] The rectangular metal frame has a clip groove on the bottom surface of the left side frame and the bottom surface of the right side frame, and a tracking hole on the left side frame and the right side frame.

[0009] The rectangular metal frame has a stacked through hole at each of its four corners.

[0010] Furthermore, the tray carrier also includes a fixing clip for limiting, connecting, and fixing the rectangular metal frame to the pick-and-place machine.

[0011] Furthermore, the fixing clip includes a straight rib and a curved hanger, which are assembled and connected by a fixing pivot, and a spring is provided between the straight rib and the curved hanger; a limiting hole is provided at the left end of the straight rib.

[0012] Furthermore, the long carrier is provided with multiple placement slots for placing loose components.

[0013] Furthermore, the rectangular metal frame is 330mm long, 310mm wide, and 15-40mm thick; the rectangular through hole is 280mm long and 260mm wide; and the diameter of the stacked through holes is 10-20mm.

[0014] Furthermore, the rectangular metal frame is made of 45# steel, or 40Cr stainless steel, or hard aluminum alloy.

[0015] Furthermore, the rectangular metal frame is provided with tag number marking information points, and the long strip vehicle is also provided with tag number identification area.

[0016] Furthermore, the pallet carrier also includes a column for stacking and storing multiple rectangular metal frames; a cylindrical block protrudes from the upper and lower ends of the column, and the cylindrical block fits into the stacked through holes.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides a pallet carrier suitable for bulk components, such as... Figure 1-2 As shown, it includes a rectangular metal frame 1 and a detachable and assembleable long strip carrier 2;

[0029] The rectangular metal frame 1 has a rectangular through hole 11 in the middle. The four side walls of the rectangular through hole 11, namely the upper, lower, left and right, are provided with mounting platforms 12. The mounting platform 12 on the upper side wall is provided with multiple upper slots 13, and the mounting platform 12 on the lower side wall is provided with multiple lower slots 14. An upper slot 13 and a lower slot 14 that are opposite each other form a pair of snap-fit ​​structures.

[0030] The long strip carrier 2 is placed on the rectangular through hole 11 and contacts the mounting platform 12; the upper end and the lower end of the long strip carrier 2 respectively have an upper locking block 23 and a lower locking block 24 protruding from them, and the upper locking block 23 and the lower locking block 24 respectively fit into the upper locking groove 13 and the lower locking groove 14 of a set of locking structures.

[0031] The rectangular metal frame 1 has a clip groove 3 on the bottom surface of the left side frame and the bottom surface of the right side frame respectively. A pinhole 16 is provided on the left side frame and the right side frame of the rectangular metal frame 1 respectively. The pinhole 16 is located at the position of the rectangular metal frame corresponding to the middle of the clip groove 3. The two cooperate to fix the fixing clip of the pallet carrier.

[0032] The rectangular metal frame 1 has a stacked through hole 15 at each of its four corners.

[0033] Specifically, the rectangular metal frame can be made of 45# steel, or 40Cr stainless steel, hard aluminum alloy, or other metals, to achieve structural stability and good load-bearing capacity.

[0034] Specifically, the rectangular metal frame is 330mm long, 310mm wide, and 15-40mm thick. To reduce structural weight and improve ease of use, the present invention sets the rectangular metal frame as a hollow structure, that is, the middle of the rectangular metal frame is opened up and a rectangular through hole is set, the rectangular through hole is 280mm long and 260mm wide.

[0035] Specifically, the bottom surfaces of the left and right frames of the rectangular metal frame are respectively provided with screw holes, and the clip slots are fixedly installed by screws.

[0036] Specifically, the rectangular metal frame is provided with reference retrieval marking points, and the elongated carrier is also provided with reference retrieval marking areas. In applications, many rectangular metal frames and elongated carriers are used to place loose components, so it is necessary to record the model and location information of the rectangular metal frames and elongated carriers for easy retrieval and pick-and-place machine programming. Therefore, this invention provides reference retrieval marking points on the left side of the rectangular metal frame and reference retrieval marking areas at the upper and lower locking blocks on the elongated carrier. The reference retrieval marking points and reference retrieval marking areas work together to record and identify component model information and corresponding placement position information.

[0037] Specifically, the material of the elongated carrier is not limited, but it is preferably made of rigid antistatic plastic or lightweight and non-deformable aluminum alloy. Each elongated carrier has multiple identical placement slots, the shape and size of which are designed according to the external dimensions of the loose components, for placing these components. Different types of elongated carriers can be distinguished based on the shape of the placement slots, with each type corresponding to a specific type of loose component. The number of placement slots on different elongated carriers may vary. Specifically, the pallet carrier also includes fixing clips for limiting, connecting, and securing the rectangular metal frame to the pick-and-place machine.

[0038] Specifically, such as Figure 3As shown, the fixing clip 4 includes a straight rib 41 and a curved hanger; the left side of the straight rib 41 has an arched block protruding downwards, and the middle of the arched block has a through mounting groove, with first channels on both sides of the mounting groove; the curved hanger includes a short rib 42, a mounting part, and a hook part 43, the thickness of the mounting part is less than that of the short rib 42 and the hook part 43, and the mounting part has a second channel; the mounting part is embedded into the mounting groove of the arched block, and a fixed rotating shaft passes through the first and second channels to achieve a fixed connection between the straight rib 41 and the curved hanger. A spring is provided between the right side of the straight rib 41 and the hook part 43 to achieve clamping and fixing in the pick-and-place machine; the hook direction of the hook part 43 faces the straight rib 41.

[0039] Specifically, the pallet carrier also includes a column for stacking and storing multiple rectangular metal frames; a cylindrical block protrudes from the upper and lower ends of the column, and the cylindrical block is fitted into the stacked through hole; the diameter of the cylindrical block is equal to or slightly smaller than the diameter of the stacked through hole, and the height of the cylindrical block is slightly less than half the thickness of the rectangular metal frame.

[0040] like Figure 4 As shown, the stacked storage of each pair of rectangular metal frames specifically includes:

[0041] On the front of a rectangular metal frame, four stacked through holes are used to fit a column; four stacked through holes of another rectangular metal frame are aligned with these four columns, and the columns are inserted into the stacked through holes from the back of the other rectangular metal frame.

[0042] Specifically, the height of the columns should be such that the components and clamping slots on the stacked long strip carriers do not come into contact with the upper and lower long strip carriers, and that the rectangular metal frames are placed stably in the stack.

[0043] In practical applications, firstly, the pick-and-place machine program is preset, and a long strip carrier of the same type as the loose component to be placed is selected. The loose component to be placed is then placed on the long strip carrier. A pair of snap-fit ​​structures are selected, and the upper and lower snap-fit ​​blocks of the long strip carrier are tightly fitted into the snap-fit ​​structure. Multiple long strip carriers of the same or different types can be placed on a single rectangular metal frame, thus allowing multiple loose components of various types to be placed simultaneously. The hooks (i.e., the hook heads of the bent parts) of the fixing clamps are fixed in the preset slots of the pick-and-place machine. The rectangular metal frame equipped with the long strip carriers is moved so that the straight ribs of the fixing clamps are inserted into the clamp slots from the left end, and the positions of the limiting holes and the pin holes are aligned. At this time, the limiting pins are inserted from top to bottom into the limiting holes of the fixing clamps through the pin holes of the rectangular metal frame, completing the position fixation of the rectangular metal frame and the pick-and-place machine. This ensures that the pick-and-place head accurately identifies the position information of the loose components. Figure 5 As shown. Next, debug the pick-and-place machine program, identify the tag number identification area of ​​the long carrier, and after confirming the tag number information, the placement operation can begin.

[0044] After mounting, remove the rectangular metal frame using the method described above.

[0045] When storing, the loading equipment and loose components placed on it can be stored by stacking the metal frame directly through the columns and stacked through holes without removing the loading equipment and loose components placed on it.
