[0002] SMT refers to the series of processes performed on printed circuit boards (PCBs). PCBs are printed circuit boards, and SMT stands for surface mount technology, a popular technique and process in the electronics assembly industry. During SMT production, the workpieces need to be transported. Traditionally, this transport process is manual, but labor-intensive.

[0003] To solve the above problems, Chinese patent publication number CN217417149U discloses an easy-to-install anti-jamming SMT patch conveying assembly, comprising a fixed plate, a plurality of rollers rotatably connected to the inner side of the fixed plate, a transmission belt is provided on the outer side of the roller, 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, a movable limit plate is fixedly connected to the output end of the electric telescopic rod, and a first limit groove is provided at the lower end of the fixed limit plate; the conveying assembly uses a mechanical mechanism to replace manual labor to convey the workpiece, thereby reducing the intensity of manual labor.

[0004] The above-mentioned conveying assembly has the following problems during actual use: it can only convey a single workpiece at a time. If this method is used to convey a large number of workpieces, it will inevitably require multiple conveyings, resulting in a longer entire conveying cycle and reduced work efficiency. Summary of the Invention

[0007] The principles and advantages of this solution are:

[0008] 1. This solution divides the interior of the storage box into multiple storage spaces through multiple partitions. Compared with the existing technology, this solution can store multiple workpieces to be processed in the storage box at the same time, so that the storage box can transport multiple workpieces to be processed each time, shortening the entire transportation cycle and improving work efficiency.

[0009] 2. The transparent layer of this solution has a simple opening and closing operation mode. When it is opened, the workpiece to be processed can be stored in the storage box. When it is closed, the outer shell can be sealed, thereby achieving the sealing of the storage box. The outer shell can prevent dust from adhering to the workpiece to be processed on the one hand, and can also prevent collision with foreign objects on the other hand, thereby protecting the workpiece to be processed.

[0010] 3. The storage box of this solution is connected to the bottom of the top block through the side blocks and the outer shell, thereby enhancing the stability of the connection between the storage box and the top block.

[0011] Furthermore, the inner wall of the shell is provided with vertical sliding grooves on both sides of the storage box, 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 is provided on the slider for abutting against the bottom of the side block, and the side block is located in the gap at both ends of the U-shaped block; and it also includes a power mechanism for driving the two U-shaped blocks to move vertically at the same time.

[0012] With the above arrangement, the two U-shaped blocks are simultaneously driven upward by the power mechanism, and the bending part of the U-shaped block is against the bottom of the side block, that is, the U-shaped block can be used to support the side block, and then support the storage box, that is, the position of the storage box can be supported and reinforced, and the stability of the connection between the storage box and the top block is further enhanced; and, 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 stability of the connection between the storage box and the top block.

[0013] Furthermore, the power mechanism includes side grooves provided on the inner wall of the outer shell and located on both sides of the storage box, a power shaft rotatably connected to the inner wall of the outer shell and located 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, a cam body and a disc are coaxially connected on the power shaft, the cam body is abutted 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 point of the disc; it also includes a power part for driving the two power blocks to move horizontally, and a stop part for stopping the power block.

The power blocks drive the disc to rotate through the swing arm, the disc drives the power shaft to rotate, and the power shaft drives the cam body to rotate. The raised part of the cam body squeezes the U-shaped block to move upward. When the bending part of the U-shaped block abuts against the bottom of the side block, the power block is stopped by the stop part, so that the U-shaped block is also stopped, that is, the U-shaped block can be used to support the side block.

[0015] Furthermore, baffles are provided on both sides of the top of the shell located at the storage box, 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 baffle, and limit blocks are provided on the side walls of the bottom plates; a lifting block is provided on the top of the U-shaped block, and a top plate is provided on the top of the lifting block, and guide grooves are provided on both sides of the top of the top plate, and hanging plates are slidably connected in the guide grooves, and a third spring is provided between the hanging plate and the guide groove, and an elastic layer is provided at the bottom of the hanging plate for resisting against the top of the limit block; and an adjustment mechanism is also included for adjusting the distance between the two hanging plates.

[0016] When the U-shaped block is in a downward motion, the lifting block drives the top plate and the hanging plate to move upward, so that the hanging plate is higher than the limit block. The distance between the two hanging plates is increased by the adjustment mechanism, that is, the two hanging plates are separated, the hanging plates and the elastic layer are located above the limit block, and the elastic layer is offset from the limit block. That is, the hanging plates and the elastic layer are used to support the U-shaped block through the top plate and the lifting block, thereby improving the stability of the U-shaped block's support for the side blocks.

When the U-shaped block stops, the lifting block also stops, and the hanging plate and the elastic layer are located above the limit block, and the elastic layer is against the limit block.

[0019] Furthermore, a strip groove is provided at the bottom of the baffle, in which a strip block is slidably connected, and a hook and a second rack are provided on the strip block; a side shaft is rotatably connected to the bottom plate, and a second gear and a third gear are coaxially connected to the side shaft, and the second gear is engaged with the second rack; a third rack is provided on the side wall of the lifting block, and the third gear is located on the motion trajectory of the third rack, and the third gear can be engaged with the third rack; an elastic block for hanging on the hook is provided between the two hanging plates, and the elastic block is arc-shaped.

[0020] When the lifting block stops, the elastic block is hung on the hook, so that 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's support for the side blocks, and making the fixed position of the storage box more stable.

[0021] Furthermore, the power unit includes a transverse shaft rotatably connected to the outer shell, a transverse groove provided on the inner wall of the outer shell, an external rack fixed to the bottom of the top seat and located 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 curved groove is provided on the cylindrical cam, and a moving block is slidably connected in the curved groove; a transverse block is transversely slidably connected in the transverse groove, the moving block is fixed to the transverse block, and both power blocks are located on the motion trajectory of the transverse block; the external rack is meshed with the external gear.

[0022] Through the above arrangement, when the outer shell moves along the length direction of the top seat, the external gear engages with the external rack to drive the transverse shaft to rotate, and the transverse shaft drives the cylindrical cam to rotate, and the cylindrical cam moves back and forth laterally in the transverse groove through the curved groove, the moving block, and the transverse block; when the transverse block moves to the left, the transverse block squeezes the power block on the left to move to the left, that is, the power block on the left moves laterally away from the storage box, and the second spring on the left is stretched; when the transverse block moves to the right, the transverse block squeezes the power block on the right to move to the right, that is, the power block on the right moves laterally away from the storage box, and the second spring on the right is stretched.

[0023] Furthermore, the stopping portion includes a wall groove opened on the side wall of the outer shell, a first wedge block fixed to the power block, a second wedge block vertically slidably connected in the wall groove for being squeezed by the first wedge block, a fourth spring is provided between the second wedge block and the wall groove, and the second wedge block is located on the movement trajectory of the first wedge block; a stopping groove is provided at the bottom of the first wedge block, and the second wedge block slides in cooperation with the stopping groove.

[0025] The present invention also intends to provide a conveying method for a conveying device for SMT patch production, so as to solve the problem of low efficiency of existing conveying components in conveying workpieces to be processed.

[0043] The specific implementation process is as follows:

[0044] When in use, the free end of the transparent layer 24 is moved away from the shell 23, so that the side port 21 and the window are connected to the outside world, and multiple workpieces to be processed are placed into multiple storage spaces through the window and the side port 21 respectively, and then the free end of the transparent layer 24 is attached to the outer wall of the shell 23, so that the window can be covered and sealed. Therefore, the shell 23 can prevent dust from adhering to the workpieces to be processed on the one hand, and can also prevent collisions with foreign objects on the other hand, thereby protecting the workpieces to be processed; and the storage box 20 is connected to the bottom of the top block 13 through the side block 25 and the shell 23, so that the stability of the connection between the storage box 20 and the top block 13 can be further enhanced.

[0045] 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 in the top groove along the length direction of the top seat 12, and then drives the shell 23 and the storage box 20 to move synchronously, that is, to realize the transportation of multiple workpieces to be processed.

[0046] During the movement of the outer shell 23 along the length direction of the top seat 12, the external gear 94 engages with the external rack 92 to drive the transverse shaft 90 to rotate, and the transverse shaft 90 drives the cylindrical cam 93 to rotate, and the cylindrical cam 93 reciprocates laterally in the transverse groove 91 through the curved 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 power block 32 on the left to move to the left, that is, the power block 32 on the left moves laterally away from the storage box 20, and the second spring 33 on the left is stretched; when the transverse block 96 moves to the right, the transverse block 96 squeezes the power block 32 on the right to move to the right, that is, the power block 32 on the right moves laterally away from the storage box 20, and the second spring 33 on the right is stretched.

[0047] During the lateral movement of the power block 32 in the direction away from the storage box 20, the power block 32 drives the first wedge block 41 to move lateral, 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 achieving the stopping of the power block 32.

[0048] When the power block 32 moves laterally in the direction away from the storage box 20, the power block 32 drives the disc 36 to rotate through the swing arm 34, and the disc 36 drives the power shaft to rotate. The power shaft drives the cam body 35 to rotate, and the raised portion of the cam body 35 squeezes the U-shaped block 30 to move upward, and the U-shaped block 30 drives the slider 81 to move upward along the path of the slide groove 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 is also stopped, and the bending part of the U-shaped block 30 is against the bottom of the side block 25, that is, the U-shaped block 30 can 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 reinforced, further enhancing the stability of the connection between the storage box 20 and the top block 13; and, both sides of the storage box 20 are provided with support and reinforcement structures, thereby ensuring the balance of both sides of the storage box 20, further enhancing the stability of the connection between the storage box 20 and the top block 13.

[0049] During the upward movement of the U-shaped block 30, the U-shaped block 30 drives the lifting block 53 to move upward, and 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 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 to move upward, so that the first gear 62 engages with the first rack 60 to drive the adjusting shaft 61 to rotate, and the adjusting shaft 61 drives the cylindrical block 63 to rotate, and the cylindrical block 63 drives the auxiliary block 65 horizontally through the first inclined surface 64. When the U-shaped block 30 moves in the horizontal direction, 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 in the horizontal direction, when the U-shaped block 30 stops, the lifting block 53 also stops, and the hanging plate 55 and the elastic layer 57 are located above the limit block 52, and the elastic layer 57 is against the limit block 52, that is, the hanging plate 55 and the elastic layer 57 are used to support the U-shaped block 30 through the top plate 54 and the lifting block 53, thereby improving the stability of the U-shaped block 30 supporting the side block 25.

[0050] 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 supporting the side block 25, thereby making the fixed position of the storage box 20 more stable.

[0051] 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 limit 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 to the top of the limit block 52, and make the elastic layer 57 and the limit block 52 collide.

[0052] This embodiment also provides a conveying method for a conveying device for SMT patch production, comprising the following steps:

[0053] Step 1: Move the free end of the transparent layer 24 away from the outer shell 23 so that the side opening 21 and the window are connected to the outside world, and place multiple workpieces to be processed through the window and the side opening 21 into the multiple storage spaces formed by multiple partitions 22 in the storage box 20, and then stick the free end of the transparent layer 24 to the outer wall of the outer shell 23 to block the window.

[0054] Step 2: 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 in the top groove along the length direction of the top seat 12, and then drives the shell 23 and the storage box 20 to move synchronously, that is, to realize the transportation of multiple workpieces to be processed.

[0055] Step 3: During the movement of the outer shell 23 along the length direction of the top seat 12, the external gear 94 is engaged with the external rack 92 to drive the transverse shaft 90 to rotate, and the transverse shaft 90 drives the cylindrical cam 93 to rotate, and the cylindrical cam 93 reciprocates laterally in the transverse groove 91 through the curved 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 power block 32 on the left to move to the left, that is, the power block 32 on the left moves laterally away from the storage box 20, and the second spring 33 on the left is stretched; when the transverse block 96 moves to the right, the transverse block 96 squeezes the power block 32 on the right to move to the right, that is, the power block 32 on the right moves laterally away from the storage box 20, and the second spring 33 on the right is stretched.

[0056] During the lateral movement of the power block 32 in the direction away from the storage box 20, the power block 32 drives the first wedge block 41 to move lateral, 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 achieving the stopping of the power block 32.

[0057] The power block 32 moves laterally in a direction 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 raised portion 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 slide groove 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 is also stopped. The bending part of the U-shaped block 30 is against the bottom of the side block 25, that is, the U-shaped block 30 can support the side block 25.

[0058] During the upward movement of the U-shaped block 30, the U-shaped block 30 drives the lifting block 53 to move upward, and 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 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 to move upward, so that the first gear 62 engages with the first rack 60 to drive the adjusting shaft 61 to rotate, and the adjusting shaft 61 drives the cylindrical block 63 to rotate, and the cylindrical block 63 drives the auxiliary block 65 to move horizontally through the first inclined surface 64, and 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, and the third spring 56 is stretched; the hanging plate 55 moves horizontally, and when the U-shaped block 30 stops, the lifting block 53 also stops, and the hanging plate 55 and the elastic layer 57 are located above the limit block 52, and the elastic layer 57 is against the limit block 52, that is, the hanging plate 55 and the elastic layer 57 are used to support the U-shaped block 30 through the top plate 54 and the lifting block 53.

[0059] 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.

[0060] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
