Description

Technical Field

[0001] The present invention relates to the technical field of tinning equipment, in particular to automatic tinning equipment. Background Art

[0002] Tinning equipment is a device that coats the product with solder paste and then places components on it, and then heats, solidifies, and cools it. Currently, most products on the market are placement machines, but they all use steel screens to print solder paste and then solidify it into shape. This type of placement machine is aimed at devices that use PCB boards as solder paste carriers. It is impossible to perform tinning operations on some irregular raised products. Therefore, for some raised product surfaces that require tinning, manual tinning and then component placement operations are still required. The tinning efficiency is very low. Although there are some equipment on the market that automatically tinns using robotic arms, and then cooperates with loaders to place tin blocks or components on products, the degree of automation is low, the workstation connection is not tight, and the entire automated process of product tinning cannot be completed.

[0003] Therefore, in response to the above problems, we need an automated equipment for tinning products with prominent appearance. Summary of the Invention

DETAILED DESCRIPTION

[0047] See also Figure 1-Figure 2 The present invention provides a technical solution: an automatic tinning equipment, including a product loading part 1 to be tinned, a solder paste dispensing part 2, a product pulling part 3, a heating track part 4, a tin block loading part 5, a tin block picking part 6, a tinning part 7, a tube loading part 8, a main chassis part 9, a tube loading chassis 10, an operation control part 11, and a heating temperature control part 12.

[0048] Principle: The material to be tinned is transferred from the loading part 1 to the solder paste part 2 through the heating track part 4 and the product pulling part 3 to be filled with solder paste. Then it is transported to the tinning part 7 in sequence and passes through the solder block loading part 5 and the solder block picking part 6 to complete the product heating, tinning, cooling and other processes. After that, it enters the tube loading part 8 through the curved guide rail to complete the product collection.

[0049] 1. Loading of products to be tinned 1: Please refer to Figure 3 The loading part 1 of the product to be tinned mainly consists of: a support plate 13, a bottom plate 14, a discharge bin assembly 15, a pipe transfer device 16, and a feeding track assembly 17.

[0050] The function of the loading part is to stack the tubes filled with the material to be tinned into the discharge bin 15, and realize the purpose of automatic tube changing and loading under the action of the tube transfer device 16 and the feeding track assembly 17.

[0051] See also Figure 4 The principle is as follows: 1. Feeding: When feeding, the material pipe 19 is clamped by the pipe pressing positioning block 21 and the rotating fixed block 28 under the action of the positioning cylinder 20, and then the pen-shaped cylinder 27 pulls the rotating connecting block 25 to drive the material pipe 19, the positioning cylinder 20, the pipe pressing positioning block 21, and the rotating fixed block 28 to rotate and lift 35°. Under the knocking of the needle-shaped cylinder 29, the product slides down due to vibration, thereby realizing feeding from top to bottom.

[0052] 2. Tube Change: During tube change, cylinder 27 lowers the rotating track to a horizontal position. Insertion block cylinder 18 activates once, dropping one tube into transfer block 31. The tube change cylinder then moves the tube and transfer block 31 to the track, pushing out the empty tube from its original position. The tube push cylinder 22 and positioning cylinder 20 further secure the tube. Once completed, the rotating track is lifted by pen-shaped cylinder 27, and the unloading process begins.

[0053] 3. Material Discharge and Stopper: The feeding track assembly 17 is equipped with a material discharge device 23 and a material stopper 24. When the post-process track is full of material, the material stopper 24 extends under the action of a pneumatic cylinder to stop the material. A track counting sensor 26 is installed between the material stopper 24. When the track counting sensor 26 detects an error, the material stopper 24 stops the material, preventing continuous feeding and ensuring smooth feeding.

[0054] 2. Solder Paste Part 2: Please refer to Figure 5 The main components of the tinning part 2 are: tinning head 32, upper support platform 35, locking ring 36, Z-axis slide 37, X-axis slide rail 38, X-axis slide 39, Z-axis power output connecting block 40, Z-axis base plate 41, mechanism support seat 42, mechanism support frame 43, X-axis operation control motor 44, Z-axis operation control motor 45, etc.

[0055] The function of the solder paste dispensing part 2 is to control the solder dispensing head 32 to run on the Z axis and the X axis to reach the solder dispensing position through two stepper motors, and then use air pressure to control the solder paste to be squeezed out to realize automatic filling of the solder paste.

[0056] See Figure 5 Principle: 1. The tinning head 32 moves in the Z axis: Figure 5 As shown, the tinning part 2 is installed on the Z-axis skateboard 37, and the Z-axis skateboard 37 is installed on the X-axis skateboard 39, and then the Z-axis skateboard 37 is connected to the motor synchronous belt of the Z-axis operation control motor 45 through the 40Z-axis power output connecting block. When the Z-axis operation control motor 45 is running, it drags the Z-axis skateboard 37 to slide on the X-axis skateboard 39, thereby realizing the operation of the tinning head on the Z-axis.

[0057] 2. 32-point tin head running action on X axis: Figure 5 As shown, the operation in the X-direction is mainly achieved by the X-axis operation control motor 44 driving the X-axis slide 39 to slide on the X-axis slide rail 38 through the synchronous belt during operation, and the Z-axis operation components (including 32 tin-point heads) are installed on the Z-axis base plate 41, and then the Z-axis base plate 41 and the X-axis slide 39 are connected together. In this way, when the X-axis operation control motor 44 drives the X-axis slide 39 to slide, it can drive the Z-axis operation components to run on the X-axis, thereby realizing the X-axis operation action of the tin-point head 32.

[0058] 3. Tinning the tinning head 32: Install the tube-packed solder paste 33 on the upper support 35 and clamp it with a locking ring 36. The amount of tinning can be adjusted by controlling the air flow in the air pipe 34.

[0059] 3. Product drawing part 3: please refer to Figure 6The product stripping part 3 is driven by three sets of pusher claw mounting blocks 52 and pusher claws 53, which are respectively driven by three pusher claw cylinders 54 to extend into and out of the product stripping gap. The pusher claw slide 48 and the connecting seat 49 are driven to slide on the product stripping module 46 by the rotation of the pusher claw motor 47, so that the connecting adjustment seat 50 and the equidistant base plate 51 fixed thereto drive the pusher claw mounting blocks 52, pusher claws 53, and the pusher claw cylinders 54 to slide together, thus realizing the automatic product stripping process. The pusher claws can also be adjusted to the appropriate height by adjusting the height of the connecting adjustment seat 50 to ensure smooth product stripping.

[0060] 4. Heating Track Part 4: Please refer to Figure 7 The heating track part 4 includes a bottom plate 55, a bottom plate support seat 56, a connecting fixture 57, a trough support block 58, a material blocking cylinder 59, a heating plate (60, 61), a track (62, 63), a cooling air blowing block 71 and other components, all of which are installed on the table panel 74. During operation, after the tinned product is fed, it stops under the action of the material blocking cylinder 59, and then under the action of the material shifting part, the product is sequentially sent to the tin injection station 64, heating station 1 65, heating station 2 66, tinning station 67, heating station 3 68, and cooling station 69, and finally enters the pipe loading part 8 through the movable track 72 or is uniformly collected in the material box 83 under the action of the movable track assembly 75. In addition, the heating temperatures of the heating station 1 65, heating station 2 66, tinning station 67, and heating station 3 68 are respectively controlled by the four temperature controllers in the 12 heating temperature control.

[0061] See also Figure 8 The movable track assembly 75 comprises a movable track 72, a track cylinder 76, a support plate 77, a vertical plate 78, a rotating shaft 79, a bottom plate 80, and a pin 81. When tinned products reach the movable track 72, they can be directly fed into the tube loading section 8 for collection under the action of the material-dispensing section. Alternatively, this mechanism can flip the track, allowing the products to slide down the blanking plate 82 into the collection box 83 for centralized collection. Operation of this mechanism primarily involves the track cylinder 76 pulling the pin 81, causing the other end of the bottom plate 80, along with the movable track 72, to flip downward around the rotating shaft 79, allowing the products on the track to be poured onto the blanking plate 82 and then onto the inclined surface of the collection box 83.

[0062] 5. Tin block loading part 5: Please refer to Figure 9 The tin block feeding part 5 includes a vibration plate 84, a chassis 85, an adjusting bottom plate 86, a straight vibration mounting plate 87, a straight vibration 88, a straight vibration trough 89, a pressing plate 90, a width bar 91, a tin block discharging assembly 92, etc. When this part is in operation, the tin blocks are arranged neatly and sent into the straight vibration trough 89 by the vibration of the vibration plate 84. Under the action of the straight vibration 88, the tin blocks continue to move forward in the straight vibration trough 89 to the position of the tin block discharging assembly 92, waiting to be picked up and enter the next process.

[0063] See also Figure 10 As shown in the figure, the tin block discharging assembly 92 extends the pneumatic finger 93 to press the pressure block 94 when the tin block is discharged, and the other end tilts up. Driven by the discharging motor 103, the distal end of the eccentric wheel 101 interacts with the bearing 102 fixed to the discharging moving block 100, so that the discharging moving block 100 drives the discharging block 97 to move toward the straight vibration trough 89, facilitating the smooth transfer of the tin block to the discharging block 97. When the optical fiber sensor 96 senses the tin block, the pneumatic finger 93 retracts, and the other end of the pressure block 94 presses the tin block in the trough under the action of the spring 95. The discharging motor 103 drives the eccentric wheel 101 to rotate, and the proximal end interacts with the bearing 102. Under the action of the tension spring 99, the discharging moving block 100 drives the discharging block 97 to move away from the trough to the pickup position of the tin block pickup part 6.

[0064] 6. Tin Block Pickup Part 6: Please refer to Figure 11 During the operation of the tin block picking part 6, the vacuum generator 114 generates suction so that the vacuum suction cup 104 can suck the product on the tin block feeding part 5, and the swing arm motor 107 cooperates with the synchronous wheel and the synchronous belt to drive the swing arm 106 and the connecting rod 105 together with the suction cup that sucks the product to swing to the side of the transfer plate 108. After the product is in place, the product is placed in the small grid of the transfer plate 108. Every time a tin block is placed in the transfer plate 108, the transfer plate 108 is acted upon by the pickup motor 107 to make the module slider 112 drive the support block 109 and the transfer plate 108 to move one grid distance on the picking module 110. After all the grids in the transfer plate 108 are filled, the tinning part 7 transfers and installs the product in the tinning station 67, and the product that has completed soldering enters the next process.

[0065] Module motor 111 drives transfer plate 108 back and forth to continuously transfer tin. Transfer plate 108 is divided into five zones, each capable of storing the amount of tin required for each soldering operation. During normal operation, tin is continuously transferred from one zone near the vacuum chuck. If an error alarm occurs or the track needs to be cleared, tin is supplied from the remaining four zones of transfer plate 108 to ensure that the heated products in the heating track can be successfully tinned.

[0066] The tin block collecting box 113 is used to catch the fallen tin blocks when the vacuum is broken (ie, leakage) after the suction cup of the tinning part 7 absorbs the tin blocks, so as to prevent the tin blocks from falling into the equipment and affecting the normal operation of the equipment.

[0067] 7. Tinning part 7: Figure 12As shown, when the tinning part 7 is working, the tin block is picked up by the material picking suction cup assembly 115 and transferred to the tinning station 67 in the heating track 4 to complete the tinning work. The mechanism uses the tinning motor 116 and the tinning XZ axis motor 122 to respectively execute the X-axis operation and Z-axis operation of the material picking suction cup assembly 115. When the material picking suction cup assembly 115 needs to run on the Z axis, the tinning XZ axis motor 122 is started, and the tinning Z axis connection mechanism 120 drives the material picking suction cup assembly 115 to move up and down on the tinning slide 119 fixed on the tinning Z axis base plate 118 through the action of the synchronous belt and synchronous wheel. When the material picking suction cup assembly 115 needs to run on the X axis, the tinning motor 116 is started, and the synchronous wheel and synchronous belt work together to drive the Z axis running component as a whole to move horizontally along the X axis on the tinning slide 117 fixed on the tinning X axis base plate 121.

[0068] 8. Pipe installation part 8: Figure 13 As shown, the pipe loading part 8 includes: a cooling fan 123, an inclined track assembly 124, a rotating track assembly 125, a pipe loading assembly 126, a pipe changing assembly 127, a material blocking assembly 128, and a material discharging assembly 129;

[0069] Principle: During the operation of this part, the cooling fan 123 continuously cools down the tinned product. After the product enters the inclined track assembly 124, the discharge assembly 129 blocks the product under the action of the cylinder until the tube changing assembly 127 senses the product through the photoelectric sensor. The blocking assembly 128 blocks the material under the action of the cylinder, and then the discharge assembly 129 discharges the material. After the product enters the rotating track assembly 125, the discharge assembly 129 blocks the material, and then the blocking assembly 128 discharges the material. The product entering the rotating track assembly 125 rotates and enters the tube loading track to complete the tube loading. When the material tube is full, the tube changing assembly will change the tube, and this cycle is used to realize the automatic tube loading process.

[0070] See also Figure 14 Among them, after the product enters the rotating track, the stop screw 130 of the rotating track assembly 125 stops the product to prevent it from rushing out of the track. The rotating motor 131 is started to drive the rotating track 133 and the rotating track cover 132 to rotate 180 degrees counterclockwise. At the same time, the follower 136 disengages from the follower pressure block 137 at one end of the inclined track assembly, and the stop nail seat 134 moves upward on the slide rail installed on the rotating slider seat 135 under the action of the spring force, so that the stop nail on the stop nail protrudes from the rotating track 133, preventing the product from being thrown out of the track during the rotation process; when it rotates to one end of the pipe loading track, the stop nail moves downward under the action of the follower pressure block to put the product into the pipe loading track, and this cycle is repeated.

[0071] Among them, see Figure 15The pipe loading assembly 126 and the pipe changing assembly 127 are shown in the figure. 138 is the pipe strip discharge bin and 139 is the pipe strip receiving bin. When the assembly is working, the pipe inserting block cylinder 141 first controls the pipe inserting block connected to it to withdraw the originally inserted pipe strip 140, so that the pipe strip 140 falls into the groove of the pipe pushing block 143, and then the next pipe strip is inserted to prevent the pipe strips 140 from overlapping; then the pipe pushing block cylinder 145 below the pipe pushing block 143 lifts the pipe pushing block 143 together with the pipe strip 140, and then the seat cylinder 146 drags the pipe pushing block connecting seat 147 to carry the pipe pushing block 143 and the pipe strip 140 to the pipe loading station 14 8 moves, and at the same time, the pipe pushing cylinder 142 and the pipe positioning block cylinder 149 retreat, and the pipe strip 140 originally in the pipe loading station 148 is sent to the pipe strip receiving bin 139 by the pipe pushing block 143, and the pipe strip cylinder 144 pushes the pipe strip into the pipe strip receiving bin 138. The pipe strip receiving bin 138 is provided with a check block to prevent the pipe strip 140 from falling back; when the new pipe strip 140 arrives at the pipe loading station 148, the pipe inserting block cylinder 141 and the pipe loading cylinder 149 extend the pipe strip to position it, waiting for material collection.

[0072] IX. Main chassis part 9: Please refer to Figure 16 The main chassis part 9 is installed on the main chassis, as shown in the figure above: the entire device controls its related actions through the touch screen and buttons in the operation control part 11; the material box 83 is used as a backup and can replace the tube loading part 8 to collect products; the dust cover 150 covers the tinning track part to ensure the soldering effect; ventilation can also be carried out with the help of the air duct 151.
