Description

Technical Field

[0001] This utility model relates to the field of pick and place machines, and in particular to a pick and place assembly and its SMT pick and place machine. Background Technology

[0002] SMT pick-and-place machines are key equipment in modern electronics manufacturing used to precisely mount surface mount components (SMD) onto printed circuit boards (PCBs). In a pick-and-place machine, the placement module is one of its core components, responsible for picking up, positioning, and placing components.

[0003] A surface mount assembly typically consists of a translation mechanism, a mounting base, a mounting bracket, a placement head, and a drive mechanism. The placement head is mounted on the mounting bracket, and the drive mechanism drives the mounting bracket to slide on the mounting base, thereby moving the placement head up and down and cooperating with the translation mechanism to perform the placement operation. However, existing drive mechanisms are usually composed of cylinders, and the output end of the cylinder is connected to the mounting bracket via a fixing component and a fixing bolt. Therefore, when disassembling multiple placement heads connected to the mounting base, it is necessary to disassemble the fixing component and fixing bolt of the cylinder output end one by one, so as to disassemble the placement head individually. This reduces the efficiency of placement head installation and disassembly during disassembly and maintenance, thus having certain defects. Utility Model Content

[0004] The purpose of this invention is to provide a surface mount assembly and an SMT placement machine thereof to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patch assembly, comprising:

[0006] Mounting base;

[0007] Mounting bracket, which is slidably mounted on the front of the mounting base;

[0008] A placement head, which is mounted on a mounting bracket;

[0009] A drive unit is mounted on a mounting base and is used to drive the mounting frame to descend.

[0012] A slide rail, which is fixedly connected to the front of the mounting base;

[0013] A connecting seat is fixedly connected to the back of the mounting bracket and slidably engaged with the outside of the slide rail.

[0014] Preferably, the reset unit includes:

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-3 The patch assembly shown includes a mounting base 1, a mounting bracket 2, a patch head 3, a drive unit 4, a reset unit 5, a slide rail 6, and a connecting base 7. The mounting bracket 2 is slidably mounted on the front side of the mounting base 1. The patch head 3 is mounted on the mounting bracket 2. The drive unit 4 is mounted on the mounting base 1 and is used to drive the mounting bracket 2 to descend. The reset unit 5 is mounted on the bottom of the mounting base 1 and is used to elastically support and limit the mounting bracket 2. Figure 1 As shown, the drive unit 4 consists of a motor, a plate, and rollers. The motor drives the plate to rotate, and the plate drives the rollers to move along a circular trajectory, thereby causing the rollers to press the mounting bracket 2 down. When the rollers rise, the reset unit 5 pushes the mounting bracket 2 to rise and reset, thus realizing the up and down movement of the patch head 3. The slide rail 6 is fixedly connected to the front of the mounting base 1, and the connecting seat 7 is fixedly connected to the back of the mounting bracket 2. The connecting seat 7 is slidably engaged with the outside of the slide rail 6, and as shown... Figure 1As shown, the mounting base 1 is mounted on the base via a translation mechanism. A notch is provided on the side of the top of the base to allow the disassembly and reset unit 5 to be removed, thus releasing the restriction on the mounting bracket 2. This allows the mounting bracket 2 to drive the connecting seat 7 to slide and separate from the slide rail 6, thereby quickly disassembling or installing the placement head 3. The translation mechanism consists of a track, a slide, a drive motor, etc., which enables the mounting base 1 to move on a plane. The drive unit 4 and the translation mechanism are controlled by the controller on the SMT placement machine, thereby enabling the placement head 3 to perform placement operations. This is existing technology and will not be described in detail here.

[0037] Furthermore, the reset unit 5 includes a support plate 51, a support member 52, and a support spring 53. The support plate 51 is installed at the bottom of the mounting base 1, the support member 52 is disposed at the bottom of the mounting frame 2 and the connecting base 7, and the support spring 53 is disposed between the support plate 51 and the support member 52. The elastic force of the support spring 53 acting on the support member 52 is sufficient to support the weight of the mounting frame 2 and the patch head 3, thereby pushing the mounting frame 2 and the patch head 3 to rise and reset.

[0038] In particular, the reset unit 5 also includes a connecting block 57 and a fixing screw 58. The connecting block 57 is fixedly connected to the top of the support plate 51. The bottom of the mounting base 1 is provided with a connecting groove that matches the connecting block 57. The outer wall of the fixing screw 58 is threadedly connected to the mounting base 1. One side of the connecting block 57 is provided with a through hole corresponding to the fixing screw 58. By removing the fixing screw 58, the locking state of multiple connecting blocks 57 can be released, thereby directly disassembling multiple support plates 51 and support members 52. This allows for the direct disassembly of multiple mounting brackets 2 and patch heads 3, thereby improving the efficiency of disassembly and maintenance of mounting brackets 2 and patch heads 3.

[0039] Furthermore, the reset unit 5 also includes a fixed rod 54, a limiting block 55, and a limiting plate 56. The top of the fixed rod 54 is fixedly connected to the support member 52, the outer wall of the fixed rod 54 is slidably sleeved with the support spring 53, and the outer wall of the fixed rod 54 is slidably interlocked with the support plate 51. The fixed rod 54 can ensure the stability of the operation of the support member 52 and the support spring 53. The limiting block 55 is fixedly connected to the bottom of the fixed rod 54, and the limiting plate 56 is fixedly connected to the bottom of the support member 52. The limiting plate 56 can limit the lowest position of the support member 52 to prevent the mounting bracket 2 from sliding downward under the action of external force, which would cause the support spring 53 to be damaged.

[0040] Furthermore, the reset unit 5 also includes a positioning plate 59 and a positioning frame 510. The positioning plate 59 is fixedly connected to one end of the support plate 51, and the positioning frame 510 is fixedly connected to the back of the mounting base 1. The outer wall of the positioning plate 59 is slidably sleeved with the positioning frame 510. The positioning plate 59 and the positioning frame 510 can further improve the stability of the support plate 51 during installation.

[0041] This embodiment provides an SMT placement machine, which includes the placement assembly described above.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
