Description

Technical Field

[0001] This utility model relates to the field of material receiving machines, and more particularly to an SMT material receiving machine that can prevent material jamming. Background Technology

[0002] SMT, or Surface Mount Technology, is used to mount electronic components without leads or with short leads onto a PCB. It is one of the most popular technologies and processes in the electronics assembly industry.

[0003] The tapes used in SMT are used in rolls. When a roll of tape is almost used up, it needs to be connected to a new roll of tape in a timely manner (using adhesive tape). During this process, the old tape is unwound and wound onto the receiving machine. The head of the old tape is continuously output to the working equipment, and the tail of the old tape is guided to the receiving machine to connect with the head of the new tape inside the receiving machine. This is to ensure that the working equipment does not stop running and to ensure production efficiency.

[0004] The tail end of the old material tape and the head end of the new material tape usually have a section of waste tape that cannot be used directly. Therefore, when splicing new and old material tapes, this waste tape section needs to be cut off first. In existing technology, such as the bonding machine for splicing new and old SMT material tapes of various widths disclosed in Chinese patent application number 201711266011.4, a specific structure and working principle of a splicing machine are described. However, it has a problem: the head end of the new material tape (via its new splicing tape conveyor) and the tail end of the old material tape (via its old splicing tape conveyor) move synchronously on the same conveyor support. During this process, if... If a shearing mechanism is used to cut off the waste material at the end of a section of the conveyor belt (the head of the new conveyor belt and the tail of the old conveyor belt are collectively referred to as the conveyor belt end), the cut-off waste material will be stuck between the head of the new conveyor belt and the tail of the old conveyor belt, and cannot be discharged from the equipment normally, causing material jamming. This will affect the connection between the head of the new conveyor belt and the tail of the old conveyor belt. Therefore, the conventional setting of the existing technology is to cut the conveyor belt end at high frequency, cutting it into small pieces, so that the waste material will be separated from the conveyor support in the form of small pieces. However, this setting will require frequent replacement of the shears due to frequent use, resulting in high maintenance costs. In addition, the excessive small pieces of waste material will cause environmental pollution in the workshop. Utility Model Content

It should also be noted that the terminology used in this utility model is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] The SMT receiving machine that can prevent material jamming provided in Embodiment 1 of this utility model, such as Figures 1 to 9 As shown, the system includes a feeding / discharging mechanism 1, a shearing mechanism 2, a waste material guiding mechanism 3, and a pusher mechanism 4. The feeding / discharging mechanism 1 includes a strip-shaped first loading platform 11 and a strip-shaped second loading platform 12. The upper surfaces of the first loading platform 11 and the second loading platform 12 are horizontal and flush. The second loading platform 12 is positioned along the strip-shaped extension direction of the first loading platform 11. The strip-shaped extension direction of the second loading platform 12 is consistent with the extension direction of the first loading platform 11. A gap is left between the first loading platform 11 and the second loading platform 12. The waste material guiding mechanism 3 includes a waste material guiding block 31 and a first driving device 32. The waste material guiding block 31 is fixed on the first driving device 32. The first driving device 32 can drive... The waste guide block 31 moves vertically; the waste guide block 31 is located in the gap between the first loading platform 11 and the second loading platform 12; the shear mechanism 2 is fixed on the first loading platform; the shear mechanism 2 can cut the material strip on the first loading platform 11; the push plate mechanism 4 includes an electric cylinder 41 and a push plate 42; the push plate 42 is fixed on the output shaft of the electric cylinder 41; the output shaft of the electric cylinder 41 extends horizontally; the extension direction of the output shaft of the electric cylinder 41 is the same as the strip extension direction of the first loading platform 11; the push plate 42 is located below the first loading platform 11; the push plate 42 can move to directly below the first loading platform 11; the push plate 42 can move to below the gap between the first loading platform 11 and the second loading platform 12.

[0029] The SMT receiving machine provided in Embodiment 1 of this utility model, which prevents material jamming, utilizes two feeding and discharging mechanisms 1 to drive the head of the new material strip and the tail of the old material strip to move relative to each other. Since the driving principle is the same, the following description uses the feeding and discharging mechanism 1 driving the head of the new material strip as an example. The feeding and discharging mechanism 1 driving the tail of the old material strip is similar. The feeding and discharging mechanism 1 drives the head of the new material strip to move until the end of the head of the new material strip moves along the strip-shaped extension direction of the first material loading platform 11 to the gap between the first material loading platform 11 and the second material loading platform 12. At this time, the first driving device 32 drives the waste guide block 31 to move vertically downward (initially, the height of the waste guide block 31 is higher than the upper surface of the first material loading platform 11, so the head of the new material strip is not affected by the waste guide block 31). When the new material belt head is moved to the second loading platform 12, the waste guide block 31 presses the new material belt head down into the gap. At this time, when the new material belt head is moved again by the feeding and discharging mechanism 1, the new material belt head passes through the gap until all the waste part of the new material belt head passes through the shear mechanism 2. The shear mechanism 2 cuts off the waste part of the new material belt head in one go. Then, the push plate mechanism 4 is used to drive the push plate 42 with the electric cylinder 41 to push the waste part of the new material belt head that has been cut off, ensuring that the waste part falls off the first loading platform 11. Then, the waste guide block 31 is driven vertically upward by the first driving device 32, so that the new material belt head with the waste cut off can move normally to the second loading platform 12 and dock with the tail of the old material belt moved by another inlet and outlet mechanism 1 for subsequent receiving process. Compared to existing technologies that require frequent cutting of waste material at the ends of the conveyor belt, where shear wear blocks and debris easily get stuck inside the equipment, affecting conveyor belt movement, this embodiment changes the equipment structure so that the waste material can be cut off in one go. Furthermore, the pushing mechanism 4 ensures that the waste material is discharged, preventing it from getting stuck and affecting subsequent material receiving.

[0030] The SMT receiving machine provided in Embodiment 1 of this utility model can prevent material jamming, which solves the problem that existing material tape waste is easily stuck inside the equipment and affects the receiving work. It can reduce the situation where waste part is stuck inside the equipment after the material tape is cut, affecting the normal receiving process.

[0031] To ensure that the shear mechanism 2 can accurately cut off the waste material, as a preferred embodiment, an imaging mechanism 5 is also included. The imaging mechanism 5 includes a camera 51, which faces the first material loading platform 11. As the material belt enters and moves through the feeding and discharging mechanism 1, the imaging mechanism 5 takes pictures of the material belt. Specifically, the camera 51 takes pictures of the material belt, and the imaging mechanism 5 uploads the acquired information to the control center. The control center determines the length of the waste material based on the captured photos and provides feedback on the movement command of the feeding and discharging mechanism 1 so that the waste material can be completely moved through the shear mechanism 2.

[0032] To prevent the waste material guiding mechanism 3 from pressing down on the end of the conveyor belt, causing the conveyor belt to tilt upwards from the first loading platform 11 and affecting the movement of the conveyor belt on the first loading platform 11, as a preferred solution, this embodiment also includes a pressing assembly 6. The pressing assembly 6 includes a pressing plate 61 and a second driving device 62. The pressing plate 61 is fixed on the second driving device 62. The second driving device 62 can drive the pressing plate 61 to move vertically and horizontally. The pressing plate 61 has a horizontal bottom surface. By driving the pressing plate 61 above the conveyor belt through the second driving device 62, the tilting of the conveyor belt is restricted. The second driving device 62 can also move away from above the first loading platform 11. The purpose of doing so is to facilitate the conveyor belt to pass directly through equipment such as a robot, so that a section of the conveyor belt (the section at the head of the new conveyor belt and the section at the tail of the old conveyor belt) can be directly placed on the first loading platform 11, eliminating the cumbersome operation of finding the end of the conveyor belt and aligning the end of the conveyor belt with the inlet of the feeding and discharging mechanism 1.

[0033] In a preferred embodiment of the second driving device 62, the second driving device 62 includes a horizontal moving component 621 and a vertical moving component 622. The vertical moving component 622 is fixed to the horizontal moving component 621. The horizontal moving component 621 can drive the vertical moving component 622 to move horizontally. The pressure plate 61 is fixed to the vertical moving component 622. The vertical moving component 622 can drive the pressure plate 61 to move vertically. The moving direction of the horizontal moving component 621 is perpendicular to the strip-shaped extension direction of the first material loading platform 11. The pressure plate 61 fixed to the vertical moving component 622 can be moved above the material belt by the horizontal moving component 621, and then the pressure plate 61 can be moved downward by the vertical moving component 622, thus restricting the degree of freedom above the material belt.

[0034] As a preferred embodiment, in this embodiment, a driven wheel 7 is rotatably fixed on the pressure plate 61; a driving wheel 8 is rotatably fixed on the feeding / discharging mechanism 1; the horizontal cross-sectional height of the upper rim of the driving wheel 8 is higher than the upper surface of the first loading platform 11; the horizontal cross-sectional height of the lower rim of the driven wheel 7 is lower than the lower surface of the pressure plate 61. The driving wheel 8 and the driven wheel 7 respectively abut against the upper and lower sides of the material belt, driving the material belt to move horizontally in a straight line. The presence of the driven wheel 7 (because the lower cross-sectional height of the driven wheel 7 is lower than the lower bottom surface of the pressure plate 61, there is a gap between the lower bottom surface of the pressure plate 61 and the material belt after the driven wheel 7 contacts the material belt) can limit the distance between the material belt and the lower bottom surface of the pressure plate 61, and prevent the material belt from sliding and affecting the normal movement of the material belt due to the contact between the pressure plates 61.

[0035] As a preferred embodiment, the feeding / discharging mechanism 1 further includes a drive motor 13; the driving wheel 8 is coaxially fixed on the output shaft of the drive motor 13; a drive gear 81 is coaxially fixed on the output shaft of the drive motor 13; a driven gear 71 is coaxially fixed on the driven wheel 7; during the movement of the pressure plate 61, the driven gear 71 and the drive gear 81 are engaged. The drive motor 13 drives the drive gear 81 to rotate, and the engagement of the driven gear 71 with the drive gear 81 controls the synchronous rotation of the driving wheel 8 and the driven wheel 7 (the rim linear velocity of the driving wheel 8 and the driven wheel 7 is the same), thus preventing the material strip from twisting and deforming due to the different directions of friction forces on its upper and lower sides.

[0036] In summary, this utility model discloses an SMT receiving machine that can prevent material jamming, relating to the field of receiving machines, including an infeed / outfeed mechanism, a shearing mechanism, a waste material guiding mechanism, and a pusher mechanism; the infeed / outfeed mechanism includes a strip-shaped first loading platform and a strip-shaped second loading platform; the upper surfaces of the first loading platform and the second loading platform are horizontal and flush; the second loading platform is disposed in the strip-shaped extension direction of the first loading platform; the strip-shaped extension direction of the second loading platform is consistent with the extension direction of the first loading platform; a gap is left between the first loading platform and the second loading platform; the waste material guiding mechanism includes a waste material guiding block and a first driving device; the waste material guiding block is fixed on the first driving device; The first driving device can drive the guide waste block to move vertically; the guide waste block is disposed in the gap between the first loading platform and the second loading platform; the scissor mechanism is fixed on the first loading platform; the scissor mechanism can cut the material strip on the first loading platform; the push plate mechanism includes an electric cylinder and a push plate; the push plate is fixed on the output shaft of the electric cylinder; the output shaft of the electric cylinder extends horizontally; the extension direction of the output shaft of the electric cylinder is the same as the strip extension direction of the first loading platform; the push plate is disposed below the first loading platform; the push plate can move to directly below the first loading platform; the push plate can move to below the gap between the first loading platform and the second loading platform. The SMT receiving machine provided by this utility model, which prevents material jamming, solves the problem that existing material strip waste easily gets stuck inside the equipment, affecting the receiving operation. It can reduce the situation where waste material gets stuck inside the equipment after the material strip is cut, affecting the normal receiving process.
