[0002] With the rapid development of the electronics manufacturing industry, the packaging process of circuit boards places higher demands on the precision and efficiency of dispensing equipment. Traditional dispensing equipment typically uses a fixed stage structure, requiring frequent downtime when changing circuit boards, resulting in reduced equipment uptime. While some existing technologies employ a dual-station alternating design, these suffer from insufficient positioning accuracy and poor support stability during station switching, easily leading to dispensing path deviation. Some equipment uses a hydraulic lifting mechanism to achieve stage positioning, but this results in complex structures and high maintenance costs. Furthermore, conventional slide rail support structures are prone to accumulated gap errors after prolonged use, affecting repeatability and positioning accuracy, and lack reliable locking mechanisms to ensure structural rigidity. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a circuit board dispensing device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A circuit board dispensing device includes a base plate, a dispensing assembly and a moving assembly for driving the dispensing assembly to move along three axes (XYZ) on the base plate, a dispensing working area on the base plate and below the dispensing assembly, first slide rails extending in a front-back direction spaced apart on the left and right sides of the base plate, a carrying plate slidably connected to the two first slide rails, a first placement groove and a second placement groove spaced apart on the front and back ends of the carrying plate, a support strip for supporting the carrying plate on the base plate and between the two first slide rails, and a locking assembly on the carrying plate. The carrying plate moves back and forth along the first slide rails, thereby alternating between the first placement groove and the second placement groove in the dispensing working area, and after switching, the carrying plate can be locked onto the support strip by the locking assembly.

[0005] In some embodiments, an armrest is provided on the front side of the loading platform.

[0006] In some embodiments, the locking assembly includes a button that is movably mounted on the upper end of the armrest seat, a transverse groove arranged in the left-right direction at the lower end of the armrest seat, a slider that slides left and right in the transverse groove, a first guide slope at the upper end of the slider, a locking pin at the lower end of the slider extending out of the transverse groove, a locking hole at one side of the support strip, a first spring connecting the transverse groove and the slider to keep the locking pin inserted into the locking hole, a second guide slope cooperating with the first guide slope at the lower end of the button, and when the button is pressed down, the second guide slope abuts against the first guide slope, thereby causing the slider to move along the transverse groove and causing its locking pin to be pulled out of the locking hole.

Detailed Implementation

[0014] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0015] like Figures 1-6 A circuit board dispensing device is shown, comprising a base plate 1, a dispensing assembly 2 and a moving assembly 10 for driving the dispensing assembly 2 to move along three axes (XYZ) on the base plate 1, a dispensing working area on the base plate 1 and below the dispensing assembly 2, first slide rails 3 extending in a front-back direction spaced apart on the base plate 1, a carrier plate 4 slidably connected on the two first slide rails 3, a first placement groove 5 and a second placement groove 6 spaced apart on the front and back of the end face of the carrier plate 4, a support strip 7 for supporting the carrier plate 4 on the base plate 1 and between the two first slide rails 3, and a locking assembly on the carrier plate 4. The carrier plate 4 moves back and forth along the first slide rails 3, thereby alternating the first placement groove 5 and the second placement groove 6 in the dispensing working area, and after switching, the carrier plate 4 can be locked on the support strip 7 by the locking assembly.

[0016] Based on the above structure, by using the sliding carrier plate 4 to switch between the first and second placement slots, the parallel operation of the feeding and dispensing processes can be achieved, reducing equipment downtime and increasing production efficiency by more than 40%.

[0017] The use of the first slide rail 3 and the supporting strip 7 in a coordinated support manner ensures smooth sliding and provides surface contact support. Compared with the traditional single slide rail structure, it greatly improves the flatness of the carrier plate 4 and effectively prevents vibration and displacement during the dispensing process.

[0018] In addition, the mechanical locking components work in conjunction with the support strip 7 to achieve a secure lock after the workstation is switched, resulting in high repeatability and positioning accuracy.

[0019] In this invention, a handrail seat 21 is provided on the front side of the carrier plate 4. The handrail seat 21 facilitates the operator to manually push and pull the carrier plate 4, reducing the operational intensity when switching work positions, while providing a force fulcrum to avoid direct contact with the carrier plate and thus preventing circuit board contamination.

[0020] See Figure 1 , Figure 3 , Figure 4 As shown, the locking assembly includes a button 31 that moves up and down on the upper end of the armrest seat 21. A transverse groove 32 is provided at the lower end of the armrest seat 21, which is arranged in the left-right direction. A slider 33 slides left and right in the transverse groove 32. A first guide slope 34 is provided at the upper end of the slider 33. The lower end of the slider 33 extends out of the transverse groove 32 and is provided with a locking pin 35. A locking hole 36 is provided on one side of the support strip 7. Of course, two sets of locking holes 36 are arranged at intervals. A first spring 37 is connected between the transverse groove 32 and the slider 33 to keep the locking pin 35 inserted into the locking hole 36. A second guide slope 38 is provided at the lower end of the button 31, which cooperates with the first guide slope 34. When the button 31 is pressed down, the second guide slope 38 abuts against the first guide slope 34, thereby causing the slider 33 to move along the transverse groove 32 and causing the locking pin 35 to be pulled out of the locking hole 36.

[0021] The specific working principle of the locking assembly is as follows: During locking, the first spring 37 actuates the slider 33, causing the locking pin 35 at the lower end of the slider 33 to insert into the locking hole 36, thereby locking the platform 4, armrest 21, and support strip 7. During unlocking, by pressing down the button 31, the second guide slope 38 abuts against the first guide slope 34, causing the slider 33 to move along the transverse groove 32 and causing the locking pin 35 to be pulled out of the locking hole 36. At this time, the platform 4 can slide along the first slide rail 3 to switch between the first placement groove 5 and the second placement groove 6. After switching positions, the button 31 is released, and the first spring 37 actuates the slider 33 again, causing the locking pin 35 at the lower end of the slider 33 to re-insert into the corresponding locking hole 36 and lock again.

[0022] To facilitate the reset of button 31, a second spring 41 is provided at the lower end of button 31.

[0023] See Figure 5 , Figure 6As shown, the dispensing assembly 2 includes a mounting plate 51 connected to the moving assembly 10. A second slide rail 52 extending in the left-right direction is provided on the front side of the mounting plate 51. Two sets of dispensing heads 53 slide at intervals within the second slide rail 52. A synchronization adjustment component is also provided on the mounting plate 51, which can drive the two dispensing heads 53 to slide synchronously inward or outward along the second slide rail 52. The synchronization adjustment component drives the two sets of dispensing heads 53 to move synchronously in opposite directions to adapt to the packaging requirements of circuit boards with different spacings. The adjustable spacing design of the dispensing heads 53 is compatible with circuit boards of various sizes, making it highly practical.

[0024] Furthermore, the synchronization adjustment assembly includes a mounting base 61 located on the upper end of the mounting plate 51, a shaft 62 rotatably mounted on the front end of the mounting base 61, a gear 63 located at the front end of the shaft 62, and racks 64 that mesh with the gears 63 on both dispensing heads 53, with the two racks 64 spaced apart on the upper and lower sides of the gear 63, respectively. The meshing structure of the gears 63 and the symmetrical racks 64 ensures strict synchronicity of the movement of the two sets of dispensing heads 53 and high precision in spacing adjustment.

[0025] Furthermore, an internal hexagonal groove 71 is provided on the front end face of the gear 63, and a locking bolt 81 is threadedly connected to the upper end of the mounting base 61. The threaded end of the locking bolt 81 can be tightened onto the shaft 62.

[0026] The gear 63 can be rotated directly by an Allen wrench, and the spacing of the dispensing head 53 can be finely adjusted without disassembling any parts. The pure mechanical transmission does not require an additional drive device, which reduces manufacturing costs and maintenance complexity. After the dispensing head 53 is adjusted, a rigid mechanical lock is provided by the locking bolt 81 to prevent the gear 63 from rotating spontaneously in a vibration environment, thereby improving the stability of the dispensing head 53.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
