Description

Technical Field

[0001] The invention relates to the field of material receiving machines, in particular to an SMT material receiving machine. Background Art

[0002] SMT is surface mounting or installation technology, which is used to install electronic components without pins or short leads on PCB. It is the most popular technology and process in the electronic assembly industry.

[0003] The material tape used in SMT is in roll form. When a roll of material tape is about to be used up, it is necessary to promptly connect this roll of material tape (old material tape) with a roll of new material tape (using tape bonding). During this process, the old material tape will be unwound and wound onto a splicer, and the head of the old material tape will be continuously output to the working equipment. The tail of the old material tape will be guided to the splicer and connected to the head of the new material tape in the splicer. This is to ensure that the working equipment does not stop running to ensure production efficiency.

[0004] In the prior art, for example, Chinese patent application No. 201710002594.3 discloses a bonding machine for old and new SMT splicing tapes that can be trimmed, which provides a specific structure and working principle of an SMT splicing machine. It mentions a cutting device, which cuts off the damaged part of the old splicing tape through the cutting device, and then bonds and sews the new splicing tape and the old splicing tape together through a bonding mechanism.

[0005] However, since there are usually some unusable waste tapes at the tail of the old tape and the head of the new tape, when connecting the old tape and the new tape, not only the tail of the old tape needs to be cut off first, but also part of the head of the new tape needs to be cut off.

[0006] The solution in the prior art is: guide the tail of the old material tape and the head of the new material tape together to a material guide trough, in which the tail of the old material tape and the head of the new material tape are arranged opposite to each other, and a scissors is arranged in the material guide trough, and the scissors work continuously, and the tail of the old material tape moves toward the scissors, and the scissors continuously cut the tail of the old material tape until the usable part of the old material tape becomes the tail of the old material tape, and the old material tape is returned; then the head of the new material tape is controlled to move toward the scissors, and the scissors cut the head of the new material tape until the usable part of the new material tape becomes the head of the new material tape, and the new material tape is returned, and then the tail of the old material tape is moved to align with the head of the new material tape, and then tape is used to stick the adjacent tails of the old material tape and the heads of the new material tape.

[0007] However, during the shearing process, in order to ensure that the material strip can move normally in the material guide trough, the end of the material strip needs to be continuously sheared into debris using scissors. The cut debris is easy to disperse, which will affect the cleanliness of the workshop, and the debris will also enter the production equipment and affect the equipment. In addition, continuous shearing causes the scissors to wear very easily, and the scissors need to be replaced frequently, which has high maintenance costs. Summary of the invention

It should be noted that the terms used in the present invention are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

[0041] The technical solutions in the embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0042] Embodiment 1:

[0043] The SMT material receiving machine provided in the first embodiment of the present invention is as follows: Figures 1 to 17 As shown, the material receiving machine body includes two material belt moving devices 1; the two material belt moving devices 1 can drive the material belt heads to move toward each other; the material belt moving device 1 includes a feeding and discharging mechanism 11, a scissor mechanism 12 and a waste material guiding mechanism 13; the feeding and discharging mechanism 11 includes a first loading platform 111 and a second loading platform 112; the upper surfaces of the first loading platform 111 and the second loading platform 112 are horizontal and flush; the upper surfaces of the first loading platforms 111 of the two material belt moving devices 1 are flush; the feeding and discharging mechanism 11 can drive the material belt to move on the first loading platform 111 and the second loading platform 112; the first loading platform 1 11 is strip-shaped; the material belt placed on the first loading platform 111 moves along the strip extension direction of the first loading platform 111; a gap is left between the first loading platform 111 and the second loading platform 112; the waste guiding mechanism 13 includes a waste guiding block 131 and a first driving device 132; the waste guiding block 131 is fixed on the first driving device 132; the first driving device 132 can drive the waste guiding block 131 to move; the waste guiding block 131 can move vertically at the gap between the first loading platform 111 and the second loading platform 112; the scissor mechanism 12 is fixed on the first loading platform 111.

[0044] The material splicing machine body provided in this embodiment is the core module of the SMT material splicing machine to connect the tail of the old material belt and the head of the new material belt. The two material belt moving devices 1 are used to pull the tail of the old material belt and the head of the new material belt respectively, so that the tail of the old material belt and the head of the new material belt are close to each other. For the head of the new material belt, in the actual pulling process, the movement of the head of the new material belt is achieved through the feeding and discharging mechanism 11. (The function of the feeding and discharging mechanism 11 is to drive the material belt to move, and the structure for driving the material belt to move is a prior art, such as Chinese patent application No. 20171 In a bonding machine for old and new SMT splicing tapes that can be trimmed, a conveying device for the new splicing tape and a conveying device for the old splicing tape can be implemented. The lower side of the tape is pressed against the upper surface of the first loading platform 111 and moves until the head of the tape moves between the first loading platform 111 and the second loading platform 112. At this time, the waste guide block 131 is above the head of the tape, and the first driving device 132 drives the waste guide block 131 vertically downward to press the head of the tape down to the first loading platform 111 and the second loading platform 112. At the gap between the platforms 112, the material strip is continued to be moved by the feeding and discharging mechanism 11, and the material strip is adjusted to align with the position of the scissor mechanism 12, and finally the material strip is sheared by the scissor mechanism 12; for the tail of the old material strip, the driving principle is the same as that of the head of the new material strip, and it is driven to move by another material strip moving device 1. After the waste material at the head of the new material strip and the waste material at the tail of the old material strip are sheared, the feeding and discharging mechanism 11 moves the head of the new material strip and the tail of the old material strip to the adhesive tape for adhesive tape; compared with the prior art, the head of the new material strip and the tail of the old material strip are driven by the same The prior art does not have a waste guiding mechanism 13, and does not have a first loading platform 111 and a second loading platform 112 that match the waste guiding mechanism 13. Therefore, in order to discharge the debris after the waste is cut out, it is necessary to repeatedly cut the waste part so that the waste is scattered in the form of small debris. The equipment provided in this embodiment can cut a long section of waste at one time, can reduce the frequency of use of the scissor mechanism 12, thereby increasing the life of the scissor mechanism 12, and can avoid the fine waste generated by multiple times of cutting the waste from polluting the working environment.

[0045] The SMT material catcher provided in Example 1 of the present invention reduces the number of times the scissor mechanism 12 is used and the generation of debris by improving the structure of the SMT material catcher, thereby solving the problem of high maintenance cost of the prior art SMT material catcher due to the need to frequently replace scissors and cleaning equipment, and can reduce the maintenance cost of the SMT material catcher.

[0046] To ensure that the scissor mechanism 12 can accurately cut off the waste part, in this embodiment, the material belt moving device 1 also includes a camera mechanism 14; the camera mechanism 14 includes a camera 141; the camera 141 faces the first loading platform 111. In order to control the scissor mechanism 12 to accurately cut the waste part at the head of the material belt, the camera mechanism 14 is used in this embodiment. When the material belt enters and moves through the feeding and discharging mechanism 11, the material belt passes through the camera mechanism 14 and is photographed and recorded. The camera mechanism 14 uploads the acquired information (to the control center, and the control center controls the operation of the material belt moving device 1 according to the feedback data).

[0047] In order to prevent the material strip from warping and affecting the cutting and tape application process, in the present embodiment, the material feeding and discharging mechanism 11 also includes a material pressing component 113; the material receiving machine body also includes a material pressing component driving mechanism 2; the material pressing component driving mechanism 2 includes a material pressing horizontal moving component 21 and a material pressing vertical moving component 22; the output shaft of the material pressing horizontal moving component 21 can move horizontally; the axis of the output shaft of the material pressing horizontal moving component 21 is perpendicular to the extension direction of the first material loading platform 111 (strip); a material pressing vertical moving component 22 is fixed on the output shaft of the material pressing horizontal moving component 21 (through a structural member); the output shaft of the material pressing vertical moving component 22 can move vertically; two material pressing components 113 are fixed on the output shaft of the material pressing vertical moving component 22; the material pressing component 113 includes a first pressing platform 1131; the lower surface of the first pressing platform 1131 is horizontal. The material pressing component 113 is used to prevent the material strip from detaching from the first material loading platform 111 (for example, when the head of the material strip is pressed down by the waste material guiding mechanism 13, other parts of the material strip may be lifted up, affecting the docking of the head of the material strip). The material pressing mechanism 11 applies downward pressure to the material strip placed on the first material loading platform 111 through the material pressing component 113. Specifically, the lower surface of the first pressing platform 1131 of the material pressing component 113 applies downward pressure to the material strip placed on the first material loading platform 111; the material pressing component 113 can be moved away from the vertical upper part of the first material loading platform 111 through the material pressing component driving mechanism 2 (specifically: the space above the first material loading platform 111 is unobstructed, and the material pressing vertical moving component 22 and the material pressing component fixed on the pressing platform 111 are operated by the material pressing horizontal moving component 21. The material pressing assembly 113 on the material vertical moving assembly moves to the top of the first material loading platform 111, and then the material pressing assembly 113 is moved vertically downward to press on the material strip on the first material loading platform 111 through the vertical electric cylinder 22 of the material pressing plate). The purpose of such a setting is to allow a section of the head part of the material strip to be directly placed from the top of the first material loading platform 111 to the bottom of the first material loading platform 111, thereby avoiding the tedious operation of finding the head of the material strip and aligning the head of the material strip to the feeding and discharging mechanism 11; since the first material loading platforms 111 of the two material strip moving devices 1 are on the same straight line, in order to simplify the structure, the material pressing assembly driving mechanism 2 of this embodiment drives the material pressing assemblies on the first material loading platforms 111 of the two material strip moving devices 1 at the same time. (The material pressing horizontal moving assembly 21 and the material pressing vertical moving assembly 22 mentioned above are structures for driving objects to achieve linear movement, which belong to the prior art, such as cylinders, electric cylinders, and screw nut assemblies, which will not be elaborated here.)

[0048] In order to specifically realize the function of the feeding and discharging mechanism 11 to move the material belt, in this embodiment, the feeding and discharging mechanism 11 includes a feeding and discharging motor 114; a driving wheel 115 is coaxially fixed on the output shaft of the feeding and discharging motor 114; the upper end horizontal section of the driving wheel 115 is higher than the upper surface of the first material loading platform 111; the pressing assembly 113 includes a driven wheel 1132; the lower surface of the first pressing platform 1131 is horizontal; the driven wheel 1132 can be rotatably fixed on the first pressing platform 1131; the driven wheel 1132 is fixed to ... The rotating shaft of 132 is horizontal; the horizontal section of the lower end of the driven wheel is lower than the lower surface of the first pressing platform 1131; a driving gear 116 is coaxially fixed on the driving wheel 115; a driven gear 1133 is coaxially fixed on the driven wheel 1132; the pressing assembly driving mechanism 2 can move the driven gear 1133 to engage with or disengage from the driving gear 116; when the driven gear 1133 is engaged with the driving gear 116, the section on the upper surface of the driving wheel 115 is opposite to the section on the lower surface of the driven wheel 1132. The working process of the material belt moving device 1 driving the head of the new material belt (or the tail of the old material belt) to move is that an external part (such as a robot) directly moves a section of the head of the material belt downward from the vertical direction to be placed on the first loading platform 111. At this time, the material pressing component 113 is moved to press the material belt through the material pressing component driving mechanism 2, and the driving gear 116 is engaged with the driven gear 1133. During this process, the camera mechanism 14 takes pictures of the material belt at all times. After analyzing the position of the head of the material belt and the length of the waste part of the head of the material belt, the control center controls the feed and discharge motor 114 to rotate, the driving wheel 115 to rotate, and the driven wheel 1132 to rotate synchronously. The driving wheel 115 and the driven wheel 1132 are respectively pressed against the upper and lower sides of the material belt to drive the material belt to move horizontally in a straight line.

[0049] In order to adapt to the connection of material strips of different widths, in this embodiment, the material connection machine body also includes a width adjustment mechanism 3; the width adjustment mechanism 3 includes a width adjustment horizontal moving component 31 and a third material loading platform 32; the third material loading platform 32 is fixed on the width adjustment horizontal moving component 31; the width adjustment horizontal moving component 31 can drive the third material loading platform 32 to move horizontally; the upper surface of the third material loading platform 32 is flush with the upper surface of the first material loading platform 111; the third material loading platform 32 is strip-shaped; the strip extension direction of the third material loading platform 32 is parallel to the strip extension direction of the first material loading platform 111. The purpose of the third material loading platform 32 is that in the process of connecting the material strips, the lower bottom surface of the material strip will be supported on the first material loading platform 111 and the third material loading platform 32, so that the material strip can be supported evenly; the purpose of the third material loading platform 32 being movable is to cope with material strips of different widths, and to support material strips of different widths by adjusting the relative position between the first material loading platform 111 and the third material loading platform 32.

[0050] As a preferred solution, in this embodiment, the width adjustment horizontal moving component 31 includes a width adjustment motor 311, a width adjustment screw rod 312 and a width adjustment screw rod nut 313; the width adjustment screw rod 312 is fixed to the output shaft of the width adjustment motor 311 through a synchronous belt drive; the width adjustment motor 311 can drive the width adjustment screw rod 312 to rotate; the width adjustment screw rod nut 313 is fixed on the width adjustment screw rod 312; when the width adjustment screw rod 312 rotates, the width adjustment screw rod nut 313 can move along the extension direction of the width adjustment screw rod 312; the extension direction of the width adjustment screw rod 312 is perpendicular to the strip extension direction of the first loading platform 111; the third loading platform 32 is fixed on the width adjustment screw rod nut 313. In the above structure, when the width adjusting screw nut 313 moves compared to the width adjusting screw 312, the width adjusting motor 311 works to drive the rotation of the width adjusting screw 312, and the width adjusting screw nut 313 is moved by the rotation of the width adjusting screw 312. The moving direction of the width adjusting screw nut 313 is the extension direction of the width adjusting screw 312. The third loading platform 32 is rotatably fixed on the width adjusting screw nut 313. By arranging a bearing structure outside the width adjusting screw nut 313, the width adjusting screw nut 313 and the third loading platform 32 are respectively fixed to the inner and outer rings of the bearing structure. The equipment as a whole restricts the third loading platform 32, so that the upper surface of the third loading platform 32 remains horizontal.

[0051] As a preferred solution, in this embodiment, the scissors mechanism 12 includes a scissors mounting frame 121, a scissors driving assembly 122, a scissors fixed blade 123 and a scissors movable blade 124; the scissors fixed blade 123 is fixedly arranged on the scissors mounting frame 121; the blade of the scissors fixed blade 123 faces downward; the blade of the scissors fixed blade 123 is horizontal; the scissors movable blade 124 can be rotatably fixed on the scissors mounting frame 121; the scissors driving assembly 122 can drive the scissors movable blade 124 to rotate relative to the scissors mounting frame 121; the blade of the scissors movable blade 124 faces upward; during the rotation of the scissors movable blade 124 relative to the scissors mounting frame 121, the angle between the blade of the scissors movable blade 124 and the blade of the scissors fixed blade 123 will change; the scissors driving assembly 122 includes a first slide rail 1221, a first slider 1222, and a second slide rail 1223. , a second slider 1224 and a pushing component 4; the first slider 1222 is slidably fixed on the first slide rail 1221; the scissors mounting frame 121 is fixed on the first slider 1222; the second slider 1224 is slidably fixed on the second slide rail 1223; the scissors movable blade 124 is rotatably fixed on the second slider 1224 by a crank; the extension directions of the first slide rail 1221 and the second slide rail 1223 are parallel; the pushing component 4 includes a screw nut mounting plate 41, a scissors screw 42 and a scissors motor 43; the scissors screw 42 is transmission-fixed on the scissors motor 43; the rotation of the scissors motor 43 can drive the scissors screw 42 to rotate; the axis of the scissors screw 42 is parallel to the extension direction of the first slide rail 1221; the screw nut mounting plate 41 is cooperated and fixed on the scissors screw 42; the screw nut mounting plate 41 and the second slider 1224 are rotatably fixed.To cut the material strip, two steps are required: one is to move the scissors to the position to be cut, and the other is to let the scissors cut the material strip; in order to prevent the blades of the scissors from scratching the material strip when the material strip moves through the material strip moving device 1, it is necessary to set the scissors away from the material strip before the material strip cutting step, and move the scissors to the position to be cut. In this embodiment, the scissors motor 43 is used to drive the scissors lead screw 42 to rotate, thereby driving the lead screw nut mounting plate 41 to move horizontally, thereby driving the second slider 1224 to move along the second slide rail 1223, thereby driving the scissors movable blade 1 fixed to the second slider 1224 24 (and the scissors mounting frame 121 connected to the scissors movable blade 124 moves horizontally, and the scissors mounting frame 121 is restricted by the first slider 1222 to move within the length range of the first slider). During this process, the scissors movable blade 124 and the scissors fixed blade 123 are always kept open. Due to the movement of the scissors mounting frame 121, the scissors movable blade 124 and the scissors fixed blade 123 move to the waiting position for cutting; when the scissors are allowed to cut the material belt, after the scissors move to the waiting position for cutting, the scissors motor 43 works to drive the scissors lead screw 42 to rotate, thereby driving the lead screw nut mounting plate 41 to move horizontally, thereby bringing The second slider 1224 is moved along the second slide rail 1223. At this time, the first slider 1222 will contact the end point of the first slide rail 1221, thereby limiting the scissor mounting frame 121 from continuing to move forward, and the second slider 1224 will continue to move along the second slide rail 1223, driving the scissor movable blade 124 to rotate relative to the scissor fixed blade 123, thereby realizing the shearing work (the shearing work and the scissor movable blade 124 rotate relative to the scissor fixed blade 123, the upper side blade of the scissor movable blade 124 intersects with the lower side blade of the scissor fixed blade 123, and the work of cutting the material strip is realized); compared with the prior art The complex scissors structure (which requires multiple drives to move the scissors to the waiting position for cutting and the scissors cutting) can be realized by only one scissors motor 43 being driven. This is because the structure of this embodiment does not require frequent cutting, and therefore does not require a special drive to drive the scissors to work. When there is a long piece of waste material at the head of the material strip, the scissors mechanism 12 can be kept in the scissors waiting position state after one cutting work, and then the feeding and discharging mechanism 11 can directly move the material strip, and after the remaining waste material is moved, the cutting work can be directly performed, thereby optimizing the cutting process.

[0052] In order to prevent the scissors movable blade 124 from being in a closed state with the scissors fixed blade 123 first and then moving to the waiting position, in this embodiment, the scissors mechanism 12 further includes a tension spring 125; the two ends of the tension spring 125 are respectively fixed on the scissors fixed blade 123 and the scissors movable blade 124; when the tension spring is naturally stretched, the scissors movable blade 124 is opened compared to the scissors fixed blade 123. The tension spring 125 can ensure that when the screw nut mounting plate 41 drives the second slider 1224 to move, and drives the scissors mounting frame 121 to move through the scissors movable blade 124, the scissors movable blade 124 is in an open state compared to the scissors fixed blade 123.

[0053] In order to specifically realize that the tape adheres the tail of the cut old material strip to the head of the cut new material strip, in the present embodiment, the material receiving machine body also includes a labeling mechanism 5; the labeling mechanism 5 includes a suction head assembly 51 for sucking the tape and a suction head assembly moving assembly 52; the suction head assembly moving assembly 52 can drive the suction head assembly 51 to move horizontally and vertically; the suction head assembly 51 includes a rest block fixed base 511, a first rest block 512 and a second rest block 513; the first rest block 512 is fixed below the rest block fixed base 511 by a spring in the vertical direction; the first rest block 512 has a first rest surface on its lower surface; a plurality of suction holes are provided on the first rest surface; the second rest block 513 has a second rest surface on its lower surface; when the first rest block 512 is not subject to the vertical upward support force from below, the first rest surface is flush with the second rest surface; the rest block fixed base 511 is fixed on the suction head assembly moving assembly 52. The suction head assembly moving assembly 52 is a prior art, and the function of the suction head assembly moving assembly 52 is to drive the suction head assembly 51 to move in three-dimensional space, which will not be described in detail here; the function of the suction head assembly 51 is to suck up the tape and stick it on two material tapes, and to loosen the tape, specifically, to suck up the tape using the suction hole on the first abutment block 512 (the suction hole has suction force, and the specific structure is a prior art and will not be described in detail here), the adhesive surface of the tape is facing away from the suction hole, and after the suction head assembly moving assembly 52 moves the suction head assembly 51 above the material tape, the suction hole stops sucking air, and the first abutment surface of the first abutment block 512 presses the tape to the upper side of the material tape; since in this embodiment, improvements have been made to adapt to material tapes of different specifications (part 3 of the width adjustment mechanism), the labeling mechanism 5 of this embodiment needs To adhere material strips of different widths, the tape is adhered to the side of the material strip, and the tape needs to be adhered to the upper surface and the lower surface of the material strip at the same time. To achieve this purpose, in this embodiment, the tape is placed at the edge of the upper surface of the material strip through the first abutment block 512, and then the suction head assembly moving assembly 52 vertically moves the suction head assembly 51 upward to adjust the position so that the first abutment block 512 is above the material strip and the second abutment block 513 is above the suspended tape. After the first abutment block 512 presses the tape against the upper surface of the material strip, the suction head assembly moving assembly 52 continues to move downward, and the spring between the fixed base 511 and the first abutment block 512 is compressed, which means that the second abutment block 513 continues to press the suspended tape downward, thereby folding the tape 90°.

[0054] In order to specifically realize the adhesion of the tape to the lower bottom surface of the two sections of material tape, in this embodiment, it also includes a label folding mechanism 6; the label folding mechanism 6 includes a folding block 61 and a folding block driving assembly 62; the folding block 61 is fixed on the folding block driving assembly 62; the folding block 61 has a fourth loading platform 611; the upper surface of the fourth loading platform 611 is flush with the first loading platform 111; the upper surface edge of the fourth loading platform 611 facing the third loading platform 32 is chamfered; the folding block driving assembly 62 can drive the folding block 61 to move horizontally; the folding block 61 is driven by the folding block driving assembly 62 to move in a direction perpendicular to the extension direction of the third loading platform 32. When the tape is folded at 90°, the fold block driving assembly 62 (a device that can drive the fold block 61 to move horizontally, which is a prior art, such as an electric cylinder, which will not be described in detail here) moves the fold block 61, and the fold block 61 is pushed toward the vertical surface of the tape and pushed to the bottom of the tape, so that the tape is attached to the lower side surface of the tape; the purpose of providing a chamfer on the upper surface edge of the fourth loading platform 611 facing the third loading platform 32 is to avoid the fold block 61 from colliding with the second abutment block 513, which causes the fold block 61 to be unable to move normally under the tape; the specific principle is that after the chamfered part of the fold block 61 contacts the second abutment block 513, the fold block 61 slides relative to the second abutment block 513 due to the chamfer, so that the fold block 61 moves downward for a distance, ensuring that the upper surface of the fold block 61 is flush with the lower surface of the tape, thereby facilitating the adhesion of the tape to the lower surface of the tape.
