Description

Technical Field

[0001] The present invention relates to the technical field of conveying, and particularly relates to a conveying device and method for SMT patch production. Background Art

[0002] SMT patching refers to the abbreviation of a series of process flows carried out on the basis of a PCB board. The PCB board is a printed circuit board, and SMT is a surface mounting technology, which is the most popular technology and process in the electronic assembly industry. During SMT patch production, it is necessary to convey the workpieces to be processed. The traditional conveying method is mainly completed manually, but such a method has a high labor intensity for workers.

[0003] To solve the above problems, a Chinese patent with the publication number CN217417149U discloses an easily installed and anti-jamming SMT patch conveying assembly, including a fixed plate. A plurality of rollers are rotatably connected to the inner side of the fixed plate. A transmission belt is arranged on the outer side of the rollers. A friction belt is fixedly connected to the outer side of the transmission belt. A fixed limit plate is fixedly connected to the rear side of the upper end of the fixed plate. An electric telescopic rod is fixedly connected to the front side of the fixed plate. The output end of the electric telescopic rod is fixedly connected to a movable limit plate. A first limit groove is opened at the lower end of the fixed limit plate; this conveying assembly uses a mechanical mechanism to convey the workpieces to be processed instead of manual labor, reducing the manual labor intensity.

[0004] The above-mentioned conveying assembly has the following problems during actual use: It can only convey a single workpiece to be processed each time. For the conveying requirements of a large number of workpieces to be processed, if such a method is used for conveying, it will inevitably be conveyed many times, resulting in a long overall conveying cycle and reducing the work efficiency. Summary of the Invention

[0005] The present invention aims to provide a conveying device for SMT patch production to solve the problem of low work efficiency of the existing conveying assembly in conveying workpieces to be processed.

[0006] To achieve the above object, the present invention adopts the following technical solution: A conveying device for SMT patch production includes a base. Pillars are provided on both sides of the top of the base. A top seat is provided between the two pillars; A top groove is provided at the bottom of the top seat. A top block is slidably connected in the top groove; A storage box is provided at the bottom of the top block. A side port is provided on the side wall of the storage box. A number of partition plates are provided in the storage box; It further includes a housing, a transparent layer, and a control mechanism for driving the top block to move along the length direction of the top seat. Side blocks are respectively provided on both sides of the storage box. The two side blocks are respectively fixedly connected to the inner walls on both sides of the housing; The housing is fixedly connected to the bottom of the top block. A window is provided on the housing. One end of the transparent layer is fixedly connected to the housing, and the other end of the transparent layer is attached to the outer wall of the housing, and the transparent layer blocks the window.

[0007] The principle and advantages of this solution are: 1. This solution divides the interior of the storage box into multiple storage spaces through multiple partition plates. Compared with the prior art, multiple workpieces to be processed can be stored simultaneously in the storage box of this solution, enabling the storage box to convey multiple workpieces to be processed each time, shortening the entire conveying cycle and improving work efficiency.

[0008] 2. The opening and closing operation mode of the transparent layer in this solution is simple. When opened, it can store workpieces to be processed into the storage box. When closed, it can seal the outer shell, thereby achieving the sealing of the storage box. Through the outer shell, on the one hand, it can prevent dust from adhering to the workpieces to be processed, and on the other hand, it can also prevent external objects from colliding, which can play a protective role for the workpieces to be processed.

[0009] 3. The storage box of this solution is connected to the bottom of the top block through side blocks and the outer shell, thereby enhancing the connection stability between the storage box and the top block.

[0010] Furthermore, vertical sliding grooves are provided on both sides of the storage box on the inner wall of the outer shell. A slider is slidably connected in the sliding groove, and a first spring is provided between the slider and the sliding groove; a U-shaped block for abutting against the bottom of the side block is provided on the slider, and the side block is located in the gap at both ends of the U-shaped block; a power mechanism for simultaneously driving the two U-shaped blocks to move vertically is also included.

[0011] Through the above settings, the power mechanism simultaneously drives the two U-shaped blocks to move upward. The bent portion of the U-shaped block abuts against the bottom of the side block, that is, the U-shaped block can be used to support the side block, and further support the storage box, that is, the position of the storage box can be supported and strengthened, further enhancing the connection stability between the storage box and the top block; moreover, support and reinforcement structures are provided on both sides of the storage box, thereby ensuring the balance of both sides of the storage box and further enhancing the connection stability between the storage box and the top block.

[0012] Furthermore, the power mechanism includes side grooves opened on the inner wall of the outer shell on both sides of the storage box, and power shafts rotatably connected to the inner wall of the outer shell on both sides of the storage box. A power block is slidably connected in the side groove, and a second spring is provided between the power block and the side groove; a swing arm is hinged on the power block, and a cam body and a disc are coaxially connected to the power shaft. The cam body abuts against the bottom of the U-shaped block, and the end of the swing arm away from the power block is hinged to the eccentric part of the disc; a power part for driving the two power blocks to move horizontally and a stopping part for stopping the power block are also included.

[0013] With the above settings, the power unit drives the two power blocks to move horizontally, causing the power blocks to move horizontally away from the storage box. The power blocks drive the disc to rotate through the swing arms, the disc drives the power shaft to rotate, the power shaft drives the cam body to rotate, and the convex part of the cam body squeezes the U-shaped block to move upward. When the bent part of the U-shaped block abuts against the bottom of the side block, the power block is stopped by the stopping part, so that the U-shaped block is also stopped, that is, the U-shaped block can support the side block.

[0014] Further, baffles are provided on both sides of the storage box at the top of the housing, and the baffles are fixedly connected to the bottom of the top block; bottom plates are provided on both sides of the bottom of the baffles, and limiting blocks are provided on the side walls of the bottom plates; a lifting block is provided on the top of the U-shaped block, a top plate is provided on the top of the lifting block, guiding grooves are provided on both sides of the top of the top plate, a hanging plate is slidably connected in the guiding grooves, a third spring is provided between the hanging plate and the guiding grooves, and an elastic layer for abutting against the top of the limiting block is provided at the bottom of the hanging plate; an adjusting mechanism for adjusting the distance between the two hanging plates is further included.

[0015] With the above settings, during the upward movement of the U-shaped block, the U-shaped block drives the lifting block to move upward, the lifting block drives the top plate and the hanging plate to move upward, so that the hanging plate is higher than the limiting block. By the adjusting mechanism, the distance between the two hanging plates is increased, that is, the two hanging plates move away from each other, the hanging plate and the elastic layer are located above the limiting block, and the elastic layer abuts against the limiting block, that is, the hanging plate and the elastic layer support the U-shaped block through the top plate and the lifting block, thereby improving the stability of the support of the U-shaped block for the side block.

[0016] Further, the adjusting mechanism includes first racks fixedly connected to both sides of the bottom of the baffle, an adjusting shaft rotatably connected to the lifting block, and auxiliary grooves provided on both sides of the bottom of the top plate. Adjusting parts are provided on both sides of the lifting block on the adjusting shaft. The adjusting part includes a first gear coaxially connected to the adjusting shaft and a cylindrical block. The first rack is located on the movement track of the first gear, and the first rack can be meshed with the first gear; a first inclined surface is provided on the cylindrical block; the auxiliary groove communicates with the guiding groove, and an auxiliary block is slidably connected in the auxiliary groove. One end of the auxiliary block is fixedly connected to the hanging plate, and the other end of the auxiliary block abuts against the first inclined surface.

[0017] With the above settings, during the upward movement of the U-shaped block, the U-shaped block drives the lifting block to move upward, the lifting block drives the top plate and the hanging plate to move upward, so that the hanging plate is higher than the limiting block; during the upward movement of the lifting block, the lifting block also drives the adjusting shaft and the first gear to move upward, so that the first gear meshes with the first rack to drive the adjusting shaft to rotate, the adjusting shaft drives the cylindrical block to rotate, and the cylindrical block drives the auxiliary block to move horizontally through the first inclined surface. The auxiliary block drives the hanging plate and the elastic layer to move synchronously, that is, the two hanging plates move away from each other and the hanging plate moves horizontally. When the U-shaped block stops moving, the lifting block also stops moving, the hanging plate and the elastic layer are located above the limiting block, and the elastic layer abuts against the limiting block.

[0018] Further, a strip-shaped groove is provided at the bottom of the baffle plate. A strip-shaped block is slidably connected in the strip-shaped groove. A hook and a second rack are provided on the strip-shaped block. A side shaft is rotatably connected to the bottom plate. A second gear and a third gear are coaxially connected to the side shaft. The second gear meshes with the second rack. A third rack is provided on the side wall of the lifting block. The third gear is located on the movement track of the third rack, and the third gear can mesh with the third rack. An elastic block for hanging on the hook is provided between the two hanging plates. The elastic block is arc-shaped.

[0019] With the above settings, during the upward movement of the lifting block, the lifting block drives the elastic block on the top plate to move synchronously, so that the elastic block is higher than the hook. When the two hanging plates move away from each other, the elastic block becomes flatter, that is, the convex position of the elastic block moves downward. During the upward movement of the lifting block, the lifting block drives the third rack to move upward, so that the third rack meshes with the third gear to drive the side shaft to rotate. The side shaft drives the second gear to rotate. The second gear meshes with the second rack to drive the strip-shaped block and the hook to move from the rear side of the storage box to the front side of the storage box, so that the hook is located below the elastic block. When the lifting block stops, the elastic block hangs on the hook. In this way, the elastic block can support the U-shaped block through the hanging plate, the top plate and the lifting block, thereby improving the stability of the U-shaped block in supporting the side block, and further making the fixed position of the storage box more stable.

[0020] Further, the power part includes a transverse shaft rotatably connected to the outer shell, a transverse groove opened on the inner wall of the outer shell, external racks fixed to the bottom of the top seat on both sides of the top block, a cylindrical cam coaxially connected to the transverse shaft, and external gears located on both sides of the cylindrical cam. A curve groove is provided on the cylindrical cam. A moving block is slidably connected in the curve groove. A transverse block is slidably connected horizontally in the transverse groove. The moving block is fixedly connected to the transverse block. Both power blocks are located on the movement track of the transverse block. The external rack meshes with the external gear.

[0021] With the above settings, during the movement of the outer shell along the length direction of the top seat, the external gear meshes with the external rack to drive the transverse shaft to rotate. The transverse shaft drives the cylindrical cam to rotate. The cylindrical cam makes the transverse block reciprocate horizontally in the transverse groove through the curve groove, the moving block and the transverse block. When the transverse block moves to the left, the transverse block squeezes the left power block to move to the left, that is, the left power block moves horizontally away from the storage box, and the left second spring is stretched. When the transverse block moves to the right, the transverse block squeezes the right power block to move to the right, that is, the right power block moves horizontally away from the storage box, and the right second spring is stretched.

[0022] Further, the stopping part includes a wall groove opened on the side wall of the outer shell and a first wedge block fixedly connected to the power block. A second wedge block for being squeezed by the first wedge block is slidably connected vertically in the wall groove. A fourth spring is provided between the second wedge block and the wall groove. The second wedge block is located on the movement track of the first wedge block. A stopping groove is provided at the bottom of the first wedge block. The second wedge block is slidably matched with the stopping groove.

[0023] With the above settings, during the lateral movement of the power block away from the storage box, the power block drives the first wedge block to move laterally, causing the first wedge block to squeeze the second wedge block downward, and the fourth spring to compress. The power block continues to move, causing the second wedge block and the stop groove to be vertically opposite. The second wedge block slides into the stop groove under the action of the fourth spring, thereby achieving the stopping of the power block.

[0024] The present invention also aims to provide a conveying method for a conveying device used in SMT patch production, so as to solve the problem of low working efficiency of the existing conveying components in conveying workpieces to be processed.

[0034] The specific implementation process is as follows: During use, drive the free end of the transparent layer 24 away from the outer shell 23, so that the side opening 21 and the window communicate with the outside. Pass multiple workpieces to be processed through the window and the side opening 21 and place them in multiple storage spaces respectively. Then, attach the free end of the transparent layer 24 to the outer wall of the outer shell 23, so as to block the window and achieve sealing. Therefore, on the one hand, the outer shell 23 can prevent dust from adhering to the workpieces to be processed, and on the other hand, it can also prevent foreign objects from colliding, and can play a protective role for the workpieces to be processed; moreover, the storage box 20 is connected to the bottom of the top block 13 through the side block 25 and the outer shell 23, so as to further strengthen the connection stability between the storage box 20 and the top block 13.

[0035] Start the motor 26. The output shaft of the motor 26 drives the one-way screw 28 to rotate, so that the top block 13 moves along the length direction of the top seat 12 in the top groove, and then drives the outer shell 23 and the storage box 20 to move synchronously, that is, the transportation of multiple workpieces to be processed is realized.

[0036] During the movement of the outer shell 23 along the length direction of the top seat 12, the external gear 94 meshes with the external rack 92 to drive the transverse shaft 90 to rotate. The transverse shaft 90 drives the cylindrical cam 93 to rotate. The cylindrical cam 93 makes a transverse reciprocating movement in the transverse groove 91 through the curve groove, the moving block 95 and the transverse block 96; when the transverse block 96 moves to the left, the transverse block 96 squeezes the left power block 32 to move to the left, that is, the left power block 32 moves transversely away from the storage box 20, and the left second spring 33 is stretched; when the transverse block 96 moves to the right, the transverse block 96 squeezes the right power block 32 to move to the right, that is, the right power block 32 moves transversely away from the storage box 20, and the right second spring 33 is stretched.

[0037] During the lateral movement of the power block 32 away from the storage box 20, the power block 32 drives the first wedge block 41 to move laterally, causing the first wedge block 41 to squeeze the second wedge block 42 downward, and the fourth spring 43 is compressed. As the power block 32 continues to move, the second wedge block 42 is vertically aligned with the stop groove 44, and the second wedge block 42 slides into the stop groove 44 under the action of the fourth spring 43, thereby achieving the stop of the power block 32.

[0038] The power block 32 moves laterally away from the storage box 20. The power block 32 drives the disc 36 to rotate through the swing arm 34. The disc 36 drives the power shaft to rotate, and the power shaft drives the cam body 35 to rotate. The convex part of the cam body 35 squeezes the U-shaped block 30 upward. The U-shaped block 30 drives the slider 81 to move upward along the path of the chute 80, and the first spring 82 is compressed. During the upward movement of the U-shaped block 30, when the power shaft stops, the U-shaped block 30 also stops. The bent part of the U-shaped block 30 abuts against the bottom of the side block 25, that is, the U-shaped block 30 can be used to support the side block 25, and then support the storage box 20, that is, the position of the storage box 20 can be supported and strengthened, further enhancing the stability of the connection between the storage box 20 and the top block 13. And support and reinforcement structures are provided on both sides of the storage box 20, thereby ensuring the balance of both sides of the storage box 20 and further enhancing the stability of the connection between the storage box 20 and the top block 13.

[0039] During the upward movement of the U-shaped block 30, the U-shaped block 30 drives the lifting block 53 upward. The lifting block 53 drives the top plate 54 and the hanging plate 55 upward, making the hanging plate 55 higher than the limit block 52. During the upward movement of the lifting block 53, the lifting block 53 also drives the adjusting shaft 61 and the first gear 62 upward, making the first gear 62 mesh with the first rack 60 to drive the adjusting shaft 61 to rotate. The adjusting shaft 61 drives the cylindrical block 63 to rotate. The cylindrical block 63 drives the auxiliary block 65 to move laterally through the first inclined surface 64. The auxiliary block 65 drives the hanging plates 55 and the elastic layer 57 to move synchronously, that is, the two hanging plates 55 move away from each other, and the third spring 56 is stretched. When the hanging plate 55 moves laterally and the U-shaped block 30 stops, the lifting block 53 also stops. The hanging plate 55 and the elastic layer 57 are located above the limit block 52, and the elastic layer 57 abuts against the limit block 52, that is, the hanging plate 55 and the elastic layer 57 support the U-shaped block 30 through the top plate 54 and the lifting block 53, thereby improving the stability of the support of the U-shaped block 30 on the side block 25.

[0040] During the upward movement of the lifting block 53, the lifting block 53 drives the elastic block 78 on the top plate 54 to move synchronously, so that the elastic block 78 is higher than the hook 72; when the two hanging plates 55 move away from each other, the elastic block 78 becomes flatter, that is, the protruding position of the elastic block 78 moves downward; during the upward movement of the lifting block 53, the lifting block 53 drives the third rack 77 to move upward, so that the third rack 77 meshes with the third gear 76 to drive the side shaft 74 to rotate, the side shaft 74 drives the second gear 75 to rotate, and the second gear 75 meshes with the second rack 73 to drive the strip block 71 and the hook 72 to move from the rear side of the storage box 20 to the front side of the storage box 20, so that the hook 72 is located below the elastic block 78. When the lifting block 53 stops, the elastic block 78 is hung on the hook 72, so that the elastic block 78 can support the U-shaped block 30 through the hanging plate 55, the top plate 54 and the lifting block 53, thereby improving the stability of the U-shaped block 30 in supporting the side block 25, and further making the fixed position of the storage box 20 more stable.

[0041] In this embodiment, a second inclined surface is provided at the bottom of the elastic layer 57, and a third inclined surface is provided at the top of the limiting block 52, and the second inclined surface is in frictional contact with the third inclined surface; during the vertical movement of the hanging plate 55 and the elastic layer 57, the hanging plate 55 and the elastic layer 57 will also move horizontally. The frictional contact between the second inclined surface and the third inclined surface can promote the hanging plate 55 and the elastic layer 57 to move above the limiting block 52 and make the elastic layer 57 abut against the limiting block 52.

[0042] This embodiment also provides a conveying method for a conveying device used in SMT patch production, including the following steps: Step 1: Drive the free end of the transparent layer 24 away from the outer shell 23, so that the side opening 21 and the window communicate with the outside world. Pass a plurality of workpieces to be processed through the window and the side opening 21 and place them into a plurality of storage spaces formed by a plurality of partition plates 22 in the storage box 20 respectively. Then stick the free end of the transparent layer 24 to the outer wall of the outer shell 23, so as to block the window.

[0043] Step 2: Start the motor 26, and the output shaft of the motor 26 drives the one-way screw 28 to rotate, so that the top block 13 moves along the length direction of the top seat 12 in the top groove, and then drives the outer shell 23 and the storage box 20 to move synchronously, that is, realizes the conveying of a plurality of workpieces to be processed.

[0044] Step 3: During the movement of the outer shell 23 along the length direction of the top seat 12, the external gear 94 meshes with the external rack 92 to drive the lateral shaft 90 to rotate. The lateral shaft 90 drives the cylindrical cam 93 to rotate. The cylindrical cam 93 drives the moving block 95 and the lateral block 96 to reciprocate horizontally in the lateral groove 91 through the curved groove; when the lateral block 96 moves to the left, the lateral block 96 squeezes the left power block 32 to move to the left, that is, the left power block 32 moves horizontally away from the storage box 20, and the left second spring 33 is stretched; when the lateral block 96 moves to the right, the lateral block 96 squeezes the right power block 32 to move to the right, that is, the right power block 32 moves horizontally away from the storage box 20, and the right second spring 33 is stretched.

[0045] During the horizontal movement of the power block 32 away from the storage box 20, the power block 32 drives the first wedge block 41 to move horizontally, so that the first wedge block 41 squeezes the second wedge block 42 to move downward, and the fourth spring 43 is compressed; the power block 32 continues to move, so that the second wedge block 42 is vertically opposite to the stop groove 44, and the second wedge block 42 slides into the stop groove 44 under the action of the fourth spring 43, thereby realizing the stop of the power block 32.

[0046] The power block 32 moves horizontally away from the storage box 20. The power block 32 drives the disc 36 to rotate through the swing arm 34. The disc 36 drives the power shaft to rotate. The power shaft drives the cam body 35 to rotate. The convex part of the cam body 35 squeezes the U-shaped block 30 to move upward. The U-shaped block 30 drives the slider 81 to move upward along the path of the chute 80, and the first spring 82 is compressed; during the upward movement of the U-shaped block 30, when the power shaft stops, the U-shaped block 30 also stops. The bent part of the U-shaped block 30 abuts against the bottom of the side block 25, that is, the U-shaped block 30 can support the side block 25.

[0047] During the upward movement of the U-shaped block 30, the U-shaped block 30 drives the lifting block 53 to move upward. The lifting block 53 drives the top plate 54 and the hanging plate 55 to move upward, so that the hanging plate 55 is higher than the limiting block 52; during the upward movement of the lifting block 53, the lifting block 53 also drives the adjusting shaft 61 and the first gear 62 to move upward, so that the first gear 62 meshes with the first rack 60 to drive the adjusting shaft 61 to rotate. The adjusting shaft 61 drives the cylindrical block 63 to rotate. The cylindrical block 63 drives the auxiliary block 65 to move horizontally through the first inclined surface 64. The auxiliary block 65 drives the hanging plate 55 and the elastic layer 57 to move synchronously, that is, the two hanging plates 55 move away from each other, and the third spring 56 is stretched; when the hanging plate 55 moves horizontally and the U-shaped block 30 stops, the lifting block 53 also stops. The hanging plate 55 and the elastic layer 57 are located above the limiting block 52, and the elastic layer 57 abuts against the limiting block 52, that is, the hanging plate 55 and the elastic layer 57 support the U-shaped block 30 through the top plate 54 and the lifting block 53.

[0048] During the upward movement of the lifting block 53, the lifting block 53 drives the elastic block 78 on the top plate 54 to move synchronously, so that the elastic block 78 is higher than the hook 72; during the separation of the two hanging plates 55, the elastic block 78 becomes flatter, that is, the protruding position of the elastic block 78 moves downward; during the upward movement of the lifting block 53, the lifting block 53 drives the third rack 77 to move upward, so that the third rack 77 meshes with the third gear 76 to drive the side shaft 74 to rotate, the side shaft 74 drives the second gear 75 to rotate, and the second gear 75 meshes with the second rack 73 to drive the strip block 71 and the hook 72 to move from the rear side of the storage box 20 to the front side of the storage box 20, so that the hook 72 is located below the elastic block 78. When the lifting block 53 stops, the elastic block 78 is hung on the hook 72, so that the elastic block 78 can support the U-shaped block 30 through the hanging plate 55, the top plate 54 and the lifting block 53.
