Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of circuit board assembly, and particularly relates to a component tray for automatic assembly of a circuit board. BACKGROUND

[0002] The circuit board of a certain product contains welding of various electronic components, covering surface-mounted device reflow welding and selective wave soldering process of direct insertion discrete devices. At present, full-automatic production of surface-mounted devices and automatic welding of direct insertion discrete devices have been realized. Before automatic wave soldering of direct insertion discrete devices, manual insertion and positioning are required. When mass production of the product is carried out, if manual insertion of individual devices is continued, there are problems of poor consistency and low production efficiency, resulting in low production efficiency and poor quality consistency of the product.

[0003] Chinese patent document with publication number CN212149698U discloses an electronic component tray, which comprises a disc body. The main structure of the disc body is square. A plurality of grooves for accommodating electronic components are arranged in an array on the disc body. A fixing column is arranged on the top surface of the disc body, and a fixing hole corresponding to the fixing column is arranged on the bottom surface of the disc body. The shape and size of the fixing column and the fixing hole are matched. The fixing column on the top surface of the disc body and the fixing hole on the bottom surface of the disc body are located at the four corner positions of the disc body. Fixing columns are also arranged on two adjacent side walls of the disc body. Corresponding fixing holes are arranged on the other two adjacent side walls of the disc body. The document solves the problem of waste of space caused by the fact that the conventional storage tray cannot realize stacking of multiple trays. However, it does not solve the problems of manual insertion and positioning before automatic wave soldering of direct insertion discrete devices, manual insertion of individual devices, poor consistency, low production efficiency, low production efficiency of the product, and poor quality consistency.

[0018] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0019] Example 1: like Figures 1-3 As shown, a component tray for automated assembly of circuit boards includes a tray body 1, and a plurality of grooves 2 are formed on the front side of the tray body 1.

[0020] Specifically, it is used for the mass automated production of circuit boards. Various types of through-hole discrete components on the circuit board are placed on a tray and put into the feeder 3 of the automatic insertion machine for automated circuit board insertion production, which can improve the production efficiency and quality consistency of circuit boards.

[0021] The tray 1 is used for the mass automated insertion production of discrete components on circuit boards. During the automatic insertion of discrete components, various types of through-hole discrete components on the circuit board are inserted into the grooves 2 of the tray 1 according to their type. The tray 1 with the inserted discrete components is then placed in the corresponding position of the feeder 3 of the automatic component insertion machine. During the automatic insertion, the inserted discrete components are removed from the tray 1 and then automatically inserted. The tray 1 not only plays a role in classifying and limiting discrete components, but also supplies complete sets of discrete components to the automatic insertion machine for the automatic insertion production of discrete components on circuit boards, thereby improving the production efficiency, insertion standardization and consistency of circuit boards.

[0022] Example 2: Based on Embodiment 1, the disk body 1 is an integrated flat plate.

[0023] Specifically, the front (placement surface) of the disk 1 is machined with various through-hole discrete component placement positions (i.e., recess 2), and the back of the disk 1 is a flat support surface; the integrated flat structure is simple, low in cost, and has better stability during use, without affecting the insertion or removal of discrete components.

[0024] Preferably, the multiple settling tanks 2 have the same or different shapes and sizes.

[0025] Specifically, it can adapt to various types of discrete components, making it more adaptable.

[0026] Preferably, the integrated flat plate is rectangular in shape.

[0027] Specifically, the four circumferential sides of the disc body 1 are adjacent to each other and share a common edge perpendicularly. The four circumferential sides are perpendicular to the placement surface and the back. The one-piece rectangular flat plate structure is simple and easy to position and fix when placed into the automatic insertion machine.

[0028] Preferably, the plurality of settling tanks 2 are divided into multiple groups, and the multiple groups of settling tanks 2 are symmetrically distributed.

[0029] Specifically, the number of discrete components placed in the tray is designed according to the number of components on the circuit board. For example, if the tray 2 contains discrete components for 8 sets of products, 8 sets of circuit boards can be automatically inserted at one time, and then the tray can be replaced. The number of discrete component trays 2 can also be increased by multiples depending on the product. One set of trays 2 corresponds to one set of products, realizing the supply of complete sets of discrete components to the automatic insertion machine. Multiple sets of trays 2 are symmetrically distributed with the center line of the tray 1 as the center line.

[0030] Preferably, the thickness of the disc body 1 is 10-15mm.

[0031] Specifically, the thickness of tray 1 is designed according to the width of the conveyor belt guide rail of the automatic insertion machine. A tray 1 with a thickness of 10-15mm can ensure that the pins of discrete components do not protrude after placement, thus avoiding damage. It can also appropriately reduce the weight of the tray and facilitate use.

[0032] Preferably, the depth of the settling tank 2 is 2-5 mm.

[0033] Specifically, the recessed groove 2 with a depth of 2-5mm not only facilitates insertion and removal but also ensures stability during use.

[0034] Preferably, the material of the disc body 1 is a non-metallic material.

[0035] Specifically, non-metallic materials are used to avoid electrostatic discharge damage to sensitive electronic components, reduce electromagnetic interference, and have a density far lower than metals, resulting in a lightweight pallet that is easy to handle manually and for automated equipment to grasp. The materials are soft and flexible, and will not scratch the casings, leads, or precision surfaces of components. Non-metallic materials include polytetrafluoroethylene (PTFE), polyurethane, and bakelite.

[0036] Preferably, the recess 2 is used for inserting components.

[0037] Specifically, the sink 2 provides precise positioning of components, protects component pins, facilitates assembly, assists in guidance, improves assembly efficiency, and enhances installation stability.

[0038] Preferably, the groove 2 is matched with the bottom and pins of the inserted component.

[0039] Specifically, redundancy design is implemented based on the bottom and pin dimensions of the device. The redundancy design can be carried out according to the actual situation to ensure that the components are placed smoothly and picked up, and to have anti-misinsertion and positioning functions.

[0040] Preferably, each set of sinks 2 is arranged in ascending order based on the size of the housing of the component to be inserted.

[0041] Specifically, based on the characteristics of the circuit board, various through-hole discrete components are assembled, and the placement surfaces of the components on the tray are classified. Combined with the size of the suction cup of the insertion machine, the components are arranged in order from smallest to largest according to the size of the casing, which is convenient for insertion or removal and easy to operate.

[0042] The method of using the component tray for automated circuit board assembly of the present invention is as follows: Before the automatic insertion of discrete components, first place the tray 1 horizontally, and then place the various types of through-hole discrete components used in the circuit board into the corresponding slots 2 according to their type and production quantity. The components should be placed with their pins facing down and the orientation of each type of component on the tray should be consistent. After placement, place the entire tray in the corresponding position of the feeder of the automatic discrete component insertion machine.

[0043] During automatic component insertion, discrete components are picked up from a tray. After the inserted discrete components are removed from the tray 1, they are automatically inserted. The tray 1 not only classifies and limits the discrete components, but also supplies complete sets of discrete components to the automatic insertion machine for the automatic insertion production of discrete components on circuit boards, thereby improving the efficiency of circuit board production and the standardization and consistency of insertion.

[0044] In the description of this invention, it should be understood that if terms such as "left," "inner," or "right" indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, it does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention.

[0045] The above examples are merely illustrative of the present invention and do not constitute a limitation on the scope of protection of the present invention. All designs that are the same as or similar to the present invention are within the scope of protection of the present invention.
