Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and in particular relates to a circuit board side labeling device. Background Technology

[0002] In today's booming electronics industry, circuit boards (PCBs), as fundamental supporting components of electronic products, directly impact the development of the entire electronics industry through the precision and efficiency of their manufacturing. Among these processes, PCB labeling is a crucial step, providing product information identification and playing a vital role in product traceability, quality control, and subsequent assembly.

[0003] Existing automated labeling equipment is mostly designed for flat surface labeling, which presents significant technical limitations when labeling the sides of circuit boards. The labeling mechanism of traditional equipment lacks the ability to precisely adapt to the sides of circuit boards. Due to slight differences in the thickness of circuit boards, problems such as label misalignment and loose adhesion can easily occur during the labeling process, affecting the readability and durability of the labels.

[0004] Meanwhile, the pressure adjustment mechanism of the existing roller label assembly is rigid and cannot dynamically adjust the bonding force according to the material characteristics of the circuit board side, which makes it easy for bubbles or wrinkles to form between the label and the board surface. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a circuit board side labeling device, which aims to solve the problem that the existing circuit board side labeling devices lack the ability to accurately adapt to the side of the circuit board.

[0017] Figure 3 This is a schematic diagram of the labeling mechanism provided by this utility model. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-3As shown, the circuit board side labeling device includes a machine base 1, on which a pair of front and rear conveyor tables 2 are provided. Between the conveyor tables 2, a pair of front and rear support tables are provided, wherein the front support table is marked as 31 and the rear support table is marked as 32. The top surface of the support table is provided with several vacuum suction cups 4. The machine base 1 is provided with a labeling mechanism and a label rolling mechanism corresponding to the front and rear support tables, respectively. The label rolling mechanism includes a base 5, on which a slide 6 is provided. A pair of upper and lower connecting plates 7 are rotatably provided inside the slide 6. Rollers 8 are rotatably provided at the front end of each connecting plate 7. A pair of fixing screws 9 are provided at the upper and lower positions of the slide 6. A pair of connecting screws 10 are provided on the back of each connecting plate 7. Tension springs 11 are provided between the upper and lower adjacent fixing screws and connecting screws located in the same position. A sliding cylinder 12 is provided on the base 5. The drive shaft of the sliding cylinder 12 is connected to the slide 6. The machine base 1 is provided with a material picking assembly located between the front and rear conveyor tables.

[0022] When using this device to side-label circuit boards, the material handling assembly can be used to transfer circuit boards between adjacent workstations. The material handling assembly includes a stand 13, on which a horizontal moving module 14 is provided. The moving end of the horizontal moving module 14 is provided with a lifting plate 15. The bottom of the lifting plate 15 is provided with three material handling suction plates 16. The moving end of the horizontal moving module 14 is provided with a lifting cylinder 17, and the drive shaft of the lifting cylinder 17 is connected to the lifting plate 15.

[0023] Specifically: When a circuit board (BPCB) is attached to each of the three picking plates on the front and rear of the material picking assembly, labeled BPCB and CPCB respectively, the lateral movement module is in its initial position. The three picking plates correspond to the end of the front conveyor, the front support platform, and directly above the rear support platform, respectively. BPCB on the front support platform has been labeled, and CPCB on the rear support platform has been labeled. The rear conveyor is ready to receive the labeled circuit board.

[0024] The lifting plate moves upwards, and the lateral movement module then drives the lifting plate to move backwards one station. During this process, the three material-grabbing suction plates move backwards synchronously, aligning circuit board A with the front support platform, circuit board B with the rear support platform, and circuit board C with the rear conveyor platform. The lifting cylinder drives the lifting plate downwards one station, causing the three circuit boards to land on their respective stations. That is, circuit board A lands on the front support platform, circuit board B lands on the rear support platform, and circuit board C lands on the rear conveyor platform, which then transports circuit board C to the next process.

[0025] After circuit board A and circuit board B are placed on the front and rear support platforms respectively, the vacuum suction cups on them firmly adhere to the circuit boards. The corresponding pick-up suction plates maintain a downward pressure on circuit boards A and B, while the remaining pick-up suction plate does not contact the rear conveyor. At the same time, the labeling mechanism and the label rolling mechanism perform labeling and label rolling operations on circuit boards A and B respectively.

[0026] When the label is firmly adhered to the circuit board using the roller label mechanism, the sliding cylinder is activated, pushing the slide block towards the circuit board. The upper and lower rollers gradually approach the side of the circuit board as the slide block moves. When the rollers contact the side of the circuit board, the elasticity of the tension springs begins to manifest. If the circuit board is thick, the upper and lower connecting plates will open outwards under the pressure of the rollers, stretching the tension springs and generating an inward restoring force, causing the rollers to press tightly against the side of the circuit board. Conversely, if the circuit board is thin, the contraction force of the tension springs will keep the rollers applying appropriate pressure to the side of the circuit board. This adaptive adjustment mechanism ensures that the rollers can automatically adjust the spacing and pressure according to the actual thickness of the circuit board, achieving a uniform rolling effect.

[0027] The sliding cylinder continues to push the slide forward, and the rollers roll on the side of the circuit board. The upper and lower rollers roll the upper and lower parts of the label respectively, gradually rolling from one end of the label to the other, firmly adhering the label to the side of the circuit board. During the rolling process, the rolling motion of the rollers not only removes air between the label and the circuit board, preventing air bubbles from forming, but also ensures full contact between the label and the circuit board surface, ensuring a tight fit.

[0028] As a specific structure, such as Figure 2 The slide block 6 is provided with a pair of washers 18, and the lower connecting plate 7 has a pair of circular grooves 19. Limiting screws 20 are inserted into the circular grooves 19 and screwed into the corresponding washers 18. The diameter of the limiting screw is smaller than the diameter of the circular groove, and the diameters of the washers and the nuts of the limiting screws are larger than the diameter of the circular groove.

[0029] The circular groove on the lower connecting plate and the limit screw work together to provide a limiting protection function. When the roller is subjected to excessive external force, the rotation angle of the lower connecting plate will be limited by the limit screw, preventing the roller from excessively squeezing the circuit board.

[0030] Furthermore, as a preferred structure, such as Figure 3 The labeling mechanism includes a fixed base 21, a rotating plate 22 is rotatably mounted on the fixed base 21, a rotating cylinder 23 is mounted on the side wall of the fixed base 21, the rotating cylinder 23 is used to drive the rotating plate 22 to rotate, a label-taking suction plate 24 is slidably mounted on the rotating plate 22, and a label-taking cylinder 25 is mounted on the rotating plate 22 to drive the label-taking suction plate to slide.

[0031] When the labeling mechanism takes the label from the label supply device and attaches it to the side of the circuit board, in this embodiment, the label-taking suction plate picks up the label by vacuum adsorption, and the rotary cylinder drives the rotary plate to rotate, so that after the label-taking suction plate takes the label from the label supply device (not shown in the figure), it rotates to the side of the circuit board for labeling. The label-taking cylinder then drives the label-taking suction plate to slide on the rotary plate to achieve precise label placement.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
