Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a multi-line receiving machine. Background Technology

[0002] Circuit boards are widely used in various technical fields due to their assemblability and testability. The demand for circuit boards is particularly huge. Therefore, factories need to mass-produce circuit boards quickly. However, current production relies on manual sorting and collection of circuit boards, resulting in low efficiency.

[0003] The circuit board receiving machine in the related technology includes a conveying device, a receiving device, and a carrying platform. After the conveying device transports the circuit board to the designated position, the receiving device transfers it to the carrying platform. Since flexible circuit boards are easily damaged, it is necessary to place isolation paper between adjacent circuit boards. The circuit board receiving machine also includes a feeding device, which is used to transport paper between adjacent circuit boards, thereby realizing full automation from material transportation to material receiving.

[0004] Regarding the above-mentioned technical solutions, the circuit board receiving machine achieves full automation from material feeding to material receiving. However, each receiving device of this circuit board receiving machine corresponds to only one loading platform and feeding device. During operation, the receiving device can only receive a single circuit board by sliding and lifting, and cannot receive multiple circuit boards simultaneously. To address this, a disclosed technology proposes a circuit board receiving machine, including a frame, a conveying device and a transfer device inside the frame, and multiple conveying areas in the conveying device that can separately transport circuit boards. This disclosed technology can achieve simultaneous conveying and receiving of multiple circuit boards.

[0005] However, the vacuum suction cups used in the above-disclosed technologies still have the following drawbacks: First, the vacuum suction cups use a centralized air source for air supply, and the air pipe is too long, which leads to a delay in vacuum establishment time; Second, when multiple suction cups are connected in parallel, there are air pressure fluctuations, which affect the stable gripping of thin circuit boards.

[0006] Therefore, it is necessary to optimize and improve its structure to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-line material receiving machine.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a multi-line material receiving machine, including a frame, a controller, a conveying device, a transfer device, an adsorption device, and a driving device for moving the adsorption device. The adsorption device includes an upper connecting rod, a lower connecting rod, a substrate, and a suction cup. The upper connecting rod is fixedly connected to the lower end of the driving device. The lower connecting rod is detachably connected to the end of the upper connecting rod away from the driving device. A connector is fixedly connected to the end of the upper connecting rod facing the lower connecting rod. A snap-fit ​​structure is provided between the lower connecting rod and the connector. The lower connecting rod and the connector are locked together by a locking sleeve. The substrate is fixedly connected to the end of the lower connecting rod away from the upper connecting rod. The suction cup is fixedly connected to the side of the substrate away from the lower connecting rod. An adsorption cavity communicating with the inside of the suction cup is provided inside the adsorption cavity. A pressure detection structure is provided inside the adsorption cavity. A negative pressure structure for forming a negative pressure in the adsorption cavity is provided on the front wall of the lower connecting rod. An alarm structure for alarming in abnormal conditions is also provided on the side wall of the lower connecting rod.

[0009] As a further description of the above technical solution:

[0010] The snap-fit ​​structure includes a first snap-fit ​​block, a second snap-fit ​​block, a first snap-fit ​​groove, and a second snap-fit ​​groove. The first snap-fit ​​block and the second snap-fit ​​block are fixedly connected to the upper end of the lower connecting rod in order from bottom to top. The first snap-fit ​​block has a rectangular cross-section when viewed from the front, and the second snap-fit ​​block has a circular cross-section when viewed from the front. The first snap-fit ​​groove is located at the end of the connector that is away from the upper connecting rod, and the second snap-fit ​​groove is located on the upper inner wall of the first snap-fit ​​groove. The inner shape of the first snap-fit ​​groove matches the shape of the first snap-fit ​​block, and the inner shape of the second snap-fit ​​groove matches the shape of the second snap-fit ​​block.

[0011] The second slot is set on the upper inner wall of the first slot to form a stepped mating surface. The inner cavity shape of the first slot matches the first slot block to achieve circumferential limiting, and the inner cavity shape of the second slot matches the second slot block to ensure coaxiality. With the above structure, when the suction cup assembly needs to be replaced, the operator only needs to align the first slot block of the lower connecting rod with the first slot and insert it. The second slot block will automatically slide into the second slot to achieve dual positioning, which solves the technical problem of repeated adjustment of alignment required by traditional flange connections.

[0012] As a further description of the above technical solution:

[0013] The upper end of the lower connecting rod is provided with a step, the locking sleeve is slidably connected to the outer wall of the upper connecting head, and the lower end of the locking sleeve is threadedly connected to the outer wall of the step.

[0014] The upper end of the connecting rod is provided with a step to form an axial stop surface. The locking sleeve is slidably connected to the outer wall of the upper connecting head and can move axially. The lower end of the locking sleeve is threadedly connected to the outer wall of the step to form a spiral clamping mechanism. When the locking sleeve rotates and presses down, the axial component force generated by the thread causes the mating surface between the connecting head and the lower connecting rod to generate a preload force of ≥50N, which effectively solves the problem of decreased positioning accuracy caused by loosening of the connection under vibration conditions.

[0015] As a further description of the above technical solution:

[0016] The pressure detection structure is a differential pressure sensor, which is fixedly connected to the upper inner wall of the adsorption chamber.

[0017] When the miniature vacuum generator is working, the differential pressure sensor can directly detect the actual working negative pressure of the suction cup, solving the measurement lag problem caused by the delay of the air tube in traditional external sensors.

[0018] As a further description of the above technical solution:

[0019] The negative pressure structure is a miniature vacuum generator, which is fixedly connected to the front wall of the lower connecting rod, and the inlet end of the miniature vacuum generator is in communication with the inside of the adsorption chamber.

[0020] The inlet of the miniature vacuum generator is connected to the inside of the adsorption chamber to form a direct gas path; when the drive device drives the suction cup to contact the circuit board, the miniature vacuum generator can establish a working negative pressure of -85kPa within 80ms, which completely solves the response delay defect caused by excessively long pipelines in centralized gas supply systems.

[0021] As a further description of the above technical solution:

[0022] The warning structure includes a base box, an alarm light, and a speaker. The base box is fixedly connected to the front wall of the lower connecting rod and located on the right side of the negative pressure structure. The alarm light and the speaker are both fixedly connected to the side of the base box away from the lower connecting rod.

[0023] The base box is fixedly connected to the front wall of the lower connecting rod and located on the right side of the negative pressure structure to form a protective shell. The alarm light and speaker are fixedly connected to the side of the base box away from the lower connecting rod to form an audible and visual alarm unit. When the differential pressure sensor detects an abnormal negative pressure, the alarm light immediately switches to a red flashing mode, and the speaker emits an 85dB alarm sound, which solves the problem of batch board drop accidents caused by the lack of real-time alarm in traditional equipment.

[0024] This utility model has the following beneficial effects:

[0025] 1. Compared with existing technologies, this multi-line receiving machine effectively solves the problem of delayed vacuum establishment caused by excessively long air pipes in traditional centralized air supply systems through its compact design that integrates a micro vacuum generator and an adsorption chamber, thus meeting the needs of high-speed assembly line operations.

[0026] 2. Compared with existing technologies, this multi-line receiving machine features an innovative modular quick-release structure that uses a dual fixing mechanism of snap-fit ​​and threaded locking to achieve rapid replacement and precise positioning of the suction cup components. This solves the problem of long maintenance time for traditional integrated suction cups and greatly improves maintenance efficiency. Attached Figure Description

[0036] To achieve rapid and accurate module docking, a connector 11 is fixedly connected to one end of the upper connecting rod 1 facing the lower connecting rod 2. A snap-fit ​​structure is provided between the lower connecting rod 2 and the connector 11. The snap-fit ​​structure includes a first snap block 13, a second snap block 14, a first snap groove 15, and a second snap groove 16.

The first snap block 13 has a rectangular cross-section when viewed from the front, and the second snap block 14 has a circular cross-section when viewed from the front. The first snap groove 15 is located at the end of the connector 11 away from the upper connecting rod 1, and the second snap groove 16 is located on the upper inner wall of the first snap groove 15.

The inner cavity shape of the first slot 15 matches the first locking block 13 to achieve circumferential limiting. The inner cavity shape of the second slot 16 matches the second locking block 14 to ensure coaxiality. With the above structure, when the suction cup assembly needs to be replaced, the operator only needs to align the first locking block 13 of the lower connecting rod 2 with the first slot 15 and insert it. The second locking block 14 will automatically slide into the second slot 16 to achieve dual positioning, which solves the technical problem of repeated adjustment of alignment required by traditional flange connection.

[0041] The substrate 4 is fixedly connected to the end of the lower connecting rod 2 away from the upper connecting rod 1 to form an installation platform.

[0043] In order to achieve rapid negative pressure establishment, a negative pressure structure for forming negative pressure in the adsorption chamber 201 is provided on the front wall of the lower connecting rod 2.

[0044] The miniature vacuum generator 6 is fixedly connected to the front wall of the lower connecting rod 2 at a distance of ≤0.3m from the inlet of the adsorption chamber 201. The inlet end of the miniature vacuum generator 6 is connected to the inside of the adsorption chamber 201 to form a direct gas path. When the driving device drives the suction cup 5 to contact the circuit board, the miniature vacuum generator 6 can establish a working negative pressure of -85kPa within 80ms, which completely solves the response delay defect caused by the excessively long pipeline in the centralized gas supply system.

[0045] In order to construct a multi-layered safety protection mechanism, the side wall of the lower connecting rod 2 is also provided with a warning structure for alarming in abnormal conditions. The warning structure includes a base box 7, an alarm light 8, and a speaker 9.

When the differential pressure sensor 10 detects an abnormal negative pressure, the alarm light 8 immediately switches to a red flashing mode, and the speaker 9 emits an 85dB alarm sound, which solves the problem of batch board drop accidents caused by the lack of real-time alarm in traditional equipment.
