Description

Technical Field

[0001] The present invention relates to the technical field of bundling and packaging, and particularly relates to an automatic circuit board bundling and packaging machine. Background Art

[0002] In the electronic device manufacturing industry, circuit boards are core components. On the production line, circuit boards need to be packaged and transported. Packaging can protect circuit boards from physical damage during transportation and prevent circuit boards from being affected by environmental factors such as dust or moisture, thus ensuring the stability of their performance.

[0003] The existing circuit board packaging is to bundle the stacked circuit boards. After bundling, the circuit boards are put into a heat shrinkable bag and the heating packaging process is carried out by an automatic shrink packaging machine. However, after the existing bundling machine horizontally bundles the circuit boards, it is necessary to manually adjust the position of the circuit boards and then vertically bundle them. Sometimes the position of the circuit boards will shift during the position adjustment process, affecting the neatness of the circuit boards. Moreover, the alignment, bundling, and conveying processes of the circuit boards do not cooperate closely enough, and the overall efficiency needs to be improved. Summary of the Invention

[0004] In order to solve the problem of slow bundling speed and low efficiency of circuit boards, the present invention provides an automatic circuit board bundling and packaging machine that can automatically use elastic ropes to bundle circuit boards.

[0005] Technical Solution: An automatic circuit board bundling and packaging machine includes a shrink packaging device. Two spaced placement plates for placing elastic ropes are connected to the left part of the shrink packaging device. A translation seat driven by an electric slide rail is provided to the right of the placement plates. A robotic arm is installed on the translation seat, and an electric claw is installed on the end effector of the robotic arm. The electric claw includes four clamping jaw parts rotatably arranged for opening the elastic ropes. Grooves for embedding the elastic ropes are opened at the ends of the clamping jaw parts. Electric push rod 1 is connected to each clamping jaw part, and a push block is connected to the telescopic rod of the electric push rod 1. The push block is used to push out the opened elastic ropes on the clamping jaw parts. A connecting plate is connected to the right side of the shrink packaging device, and a clamping member for clamping circuit boards is installed on the connecting plate.

[0006] In a preferred embodiment of the present invention, four inclined holes 1 are opened at the end of the placement plate for the clamping jaw parts to extend into, and the push blocks all have inclined surface 1.

[0007] In a preferred embodiment of the present invention, the clamping member includes a rotating rod, a right-angled block 1, an electric push rod 2, and a clamping plate. A rotating rod driven by a reduction motor is rotatably connected to the connecting plate. A right-angled block 1 is connected to the top of the rotating rod, and a clamping plate that slides up and down and is driven by the electric push rod 2 is provided on the right-angled block 1.

[0008] In a preferred embodiment of the present invention, the automatic bundling and packaging machine for circuit boards further includes a support assembly. The support assembly includes an electric push rod three, a support plate, and electric conveying wheels. The bottom of the connecting plate is connected to the electric push rod three. A support plate that slides up and down is provided in the middle of the connecting plate. The telescopic rod of the electric push rod three is connected to the support plate. Two rows of electric conveying wheels are installed on the support plate.

[0009] In a preferred embodiment of the present invention, the automatic bundling and packaging machine for circuit boards further includes a positioning assembly. The positioning assembly includes an electric push rod four, a translation rod, and a right-angle block two. An inclined hole two is opened on the connecting plate. The bottom of the connecting plate is connected to the electric push rod four. A translation rod that penetrates through the inclined hole two is connected to the telescopic rod of the electric push rod four. The top of the translation rod is connected to the right-angle block two.

[0010] In a preferred embodiment of the present invention, the automatic bundling and packaging machine for circuit boards further includes a pushing assembly. The pushing assembly includes a driving roller and a synchronous belt. Two driving rollers are rotatably connected between two placing plates. A synchronous belt is wound between the two driving rollers. The synchronous belt is located at the interval between the two placing plates. A circle of pushing parts for pushing the elastic rope above the inclined hole one is provided at intervals on the outer side of the synchronous belt.

[0011] In a preferred embodiment of the present invention, the automatic bundling and packaging machine for circuit boards further includes a placing frame, a fixed cylinder, a limiting rod, a U-shaped rod, and a driving assembly. A placing frame for placing the elastic rope is jointly connected to the tops of the two placing plates. An opening is opened at the bottom of the placing frame. Two fixed cylinders are connected to the top of the placing frame. Limiting rods with inclined surfaces two at the bottom ends are inserted on the fixed cylinders. The limiting rods extend into the placing frame. The distance between the bottom end of the limiting rod and the inner bottom of the placing frame only allows one elastic rope to pass through. The distance between the left side of the limiting rod and the inner left wall of the placing frame only allows one elastic rope to pass through. When the synchronous belt rotates, the pushing part passes through the bottom of the placing frame; A pair of U-shaped rods are slidably connected to the lower parts of both sides of the placing frame. Both ends of the U-shaped rod have limiting ends with inclined end faces; In each pair of U-shaped rods, the limiting ends of the two U-shaped rods alternately extend into the interior of the placing frame; A driving assembly is provided on the placing frame.

[0012] In a preferred embodiment of the present invention, the driving assembly includes a fixed block. Fixed blocks are connected to the lower parts of both sides of the placing frame. Rotating plates are rotatably connected to the fixed blocks. Long holes are opened at both ends of the rotating plate. Round blocks are rotatably connected to the U-shaped rods. The four round blocks are respectively located in the four long holes. Two lifting blocks driven by an electric push rod five are provided in front of the placing frame. Hinge rods are rotatably connected between the two lifting blocks and the two upper round blocks respectively.

[0013] Compared with the prior art, the present invention has the following advantages: 1. Place the circuit board on the first right-angle block, and the electric conveying wheels support the circuit board. The moving right-angle block automatically pushes a stack of circuit boards neatly to correct the position of the circuit board and avoid the deviation of the circuit board position. The electric conveying wheels can convey the bundled circuit boards to the shrink packaging device. The alignment, bundling, and conveying processes of the circuit boards are closely coordinated, and the overall working efficiency is high.

[0014] 2. After the four clamping jaws are retracted, they pass through the inner end of the first inclined hole. The clamping jaws expand and move to the outer end of the first inclined hole. The deformed elastic rope is embedded in the groove, and the clamping member clamps the circuit board. When the elastic rope on the electric claw is sleeved around the middle periphery of the circuit board, the moving push block pushes the elastic rope out of the groove. After the elastic rope shrinks, it is sleeved around the middle of the circuit board. After the clamping member and the circuit board rotate, the next elastic rope is sleeved. It can automatically complete the bundling work of the circuit board, improving the automation degree and the overall packaging efficiency.

[0015] 3. Place multiple elastic ropes into the placement frame in sequence, insert the limiting rod into the fixed cylinder, the synchronous belt rotates, and under the guiding action of the second inclined surface, the pushing part smoothly pushes the lowermost elastic rope to move onto the four first inclined holes. The two upper U-shaped rods and the two lower U-shaped rods alternately extend into the placement frame, and the limiting rod and the U-shaped rods limit the remaining elastic ropes. The pushing and bundling processes of the elastic ropes are closely coordinated, further improving the automation degree and working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention.

[0031] Example 1: An automatic bundling and packaging machine for circuit boards, refer to Figures 1-9, including a shrink packaging device 1, a placement plate 2, a translation seat 3, a robotic arm 4, an electric claw 5, a first electric push rod 6, a push block 7, a connecting plate 8 and a clamping member 9. The shrink packaging device 1 is a prior art, and its function is specifically to bag, shrink and convey the bundled circuit board 90. Two spaced placement plates 2 for placing elastic ropes 20 are fixedly connected to the left part of the front side of the shrink packaging device 1. A translation seat 3 driven by an electric slide rail is provided to the right of the placement plate 2. A robotic arm 4 is installed on the translation seat 3. An electric claw 5 is installed on the end effector of the robotic arm 4. The structure and principle of the electric claw 5 are prior art. The electric claw 5 specifically includes four rotatably arranged claw parts 51. The four claw parts 51 have states of spreading outwards and retracting inwards. Grooves 52 for embedding the elastic rope 20 are opened at the ends of the claw parts 51. The four claw parts 51 in the state of spreading outwards can open the elastic rope 20. As Figure 3 shown, four first inclined holes 21 are opened at the right end of the placement plate 2. The first inclined holes 21 are divided into an inner end and an outer end. The first inclined holes 21 are used for the claw parts 51 to extend into. Electric push rods 6 are bolted to the claw parts 51 respectively. Push blocks 7 are connected to the telescopic rods of the electric push rods 6 respectively. The push blocks 7 each have a first inclined surface 71. The push blocks 7 are used to push out the opened elastic rope 20 on the claw parts 51. A connecting plate 8 is bolted to the right side of the shrink packaging device 1. A clamping member 9 for clamping the circuit board 90 is installed on the connecting plate 8; The clamping member 9 includes a rotating rod 91, a first right-angle block 92, a second electric push rod 93 and a clamping plate 94. A rotating rod 91 driven by a reduction motor is rotatably connected to the right part of the connecting plate 8. The reduction motor is bolted to the bottom of the connecting plate 8. A first right-angle block 92 is fixedly connected to the top end of the rotating rod 91. A clamping plate 94 that slides up and down is provided on the first right-angle block 92. A second electric push rod 93 is bolted to the rear side wall of the first right-angle block 92. The telescopic rod of the second electric push rod 93 is connected to the clamping plate 94.

[0032] First step, the elastic rope 20 is placed at the right end of the placement plate 2. As Figure 3 shown, the elastic rope 20 passes through the middle of the first inclined hole 21. Control the electric claw 5 to make the four claw parts 51 retract inwards. Then control the electric slide rail to drive the translation seat 3 to move leftwards, driving the robotic arm 4 to move left. Then control the robotic arm 4 to move the electric claw 5 on the end effector to a different position. The four claw parts 51 respectively pass through the inner ends of the four first inclined holes 21 from top to bottom. Control the electric claw 5 to make the four claw parts 51 spread outwards to the initial state. The claw parts 51 move to the outer ends of the first inclined holes 21. The elastic rope 20 is embedded in the grooves 52. Specifically as Figure 5 shown, so that the elastic rope 20 is sleeved on the four claw parts 51, and the elastic rope 20 is in a deformed state of being opened.

[0033] In the second step, control the electric push rod two 93 to drive the clamping plate 94 to move upward. Manually place a stack of circuit boards 90 on the right-angle block one 92. The right angle of the circuit board 90 fits with the right angle of the right-angle block one 92, so that the circuit board 90 becomes neat. Control the electric push rod two 93 to drive the clamping plate 94 to move downward. The clamping plate 94 clamps the neat circuit board 90, and then the operator can release the circuit board 90.

[0034] In the third step, control the electric slide rail to move the translation seat 3 and the robotic arm 4 to the right to reset. Control the robotic arm 4 to adjust the positions of the electric claw 5 and the elastic cord 20 until the elastic cord 20 is sleeved around the outer periphery of the middle part of the circuit board 90 clamped by the clamping member 9. Then control the telescopic rod of the electric push rod one 6 to extend, driving the push block 7 to move. The four push blocks 7 push the elastic cord 20 out of the groove 52. When the elastic cord 20 is separated from the clamping jaw part 51, due to the setting of the inclined surface one 71, under the action of the self-elastic force of the elastic cord 20, the elastic cord 20 contracts and is sleeved around the middle part of the circuit board 90.

[0035] In the fourth step, control the reduction motor to drive the rotating rod 91 to rotate counterclockwise by 90 degrees, driving the right-angle block one 92, the electric push rod two 93, the clamping plate 94 and the clamped circuit board 90 to rotate counterclockwise by 90 degrees together. Similarly, repeat the first step and the third step to make the next elastic cord 20 sleeved around the middle part of the circuit board 90. The two elastic cords 20 in a cross shape bundle the circuit board 90, so that the bundling work of the circuit board 90 can be automatically completed, improving the automation degree and the overall packaging efficiency.

[0036] Reference Figure 2 、 Figure 4 、 Figure 7 and Figure 8 , the automatic circuit board bundling and packaging machine further includes a support assembly. The support assembly includes an electric push rod three 111, a support plate 112 and an electric conveying wheel 113. The electric push rod three 111 is bolted to the bottom of the connecting plate 8. A support plate 112 that slides up and down is provided in the middle of the connecting plate 8. The telescopic rod of the electric push rod three 111 is connected to the support plate 112. Two rows of electric conveying wheels 113 driven by a motor are installed on the support plate 112.

[0037] Reference Figure 4 、 Figure 7 and Figure 8 , the automatic circuit board bundling and packaging machine further includes a positioning assembly. The positioning assembly includes an electric push rod four 121, a translation rod 122 and a right-angle block two 123. An inclined hole two 124 is opened on the front side of the left part of the connecting plate 8. The electric push rod four 121 is bolted to the bottom of the connecting plate 8. A translation rod 122 that penetrates through the inclined hole two 124 is connected to the telescopic rod of the electric push rod four 121. The translation rod 122 moves along the inclined hole two 124. The top end of the translation rod 122 is fixedly connected to the right-angle block two 123.

[0038] First, control the telescopic rod of the electric push rod four 121 to extend, so that the translation rod 122 moves forward and left along the inclined hole two 124, driving the right-angle block two 123 to move forward and left. When the circuit board 90 is placed on the right-angle block one 92, at the same time, the circuit board 90 is located on the electric conveying wheel 113, and the electric conveying wheel 113 plays a role in supporting the circuit board 90. Then, control the telescopic rod of the electric push rod four 121 to shorten, so that the translation rod 122 moves backward and right along the inclined hole two 124, driving the right-angle block two 123 to move backward and right. The right angle of the circuit board 90 fits with the right angle of the right-angle block two 123. Thus, through the cooperation of the right-angle block one 92 and the right-angle block two 123, a stack of circuit boards 90 is automatically pushed neatly, the position of the circuit board 90 is automatically corrected, the deviation of the position of the circuit board 90 is avoided, and the neatness of the circuit board 90 is ensured. After the clamping plate 94 clamps the circuit board 90, control the electric push rod four 121 to make the translation rod 122 and the right-angle block two 123 move forward and left again, and control the electric push rod three 111 to lower the support plate 112 and the electric conveying wheel 113 to make way. The robotic arm 4 and the electric claw 5 can then perform the bundling work. After the bundling is completed, control the electric push rod three 111 to raise the support plate 112 and the electric conveying wheel 113 to reset, the clamping plate 94 releases the circuit board 90, and then control the electric conveying wheel 113 to rotate. The electric conveying wheel 113 conveys the bundled circuit board 90 to the left to the shrink packaging device 1 for subsequent packaging work. In this way, the alignment and pushing of the circuit board 90 can be automatically completed, the alignment, bundling, and conveying processes of the circuit board 90 are closely coordinated, and the overall work efficiency is high.

[0039] Embodiment 2: On the basis of Embodiment 1, referring to Figure 3 and Figure 10 , the automatic circuit board bundling and packaging machine further includes a pushing assembly. The pushing assembly includes a driving roller 131 and a synchronous belt 132. Two driving rollers 131 are rotatably connected between two placing plates 2. One of the driving rollers 131 is driven by a driving motor. A synchronous belt 132 is wound between the two driving rollers 131. The synchronous belt 132 is located at the interval between the two placing plates 2. A pushing part 133 for pushing the elastic cord 20 above the inclined hole one 21 is arranged at intervals on the outer side of the synchronous belt 132. When the elastic cord 20 is placed on the placing plate 2, the distance between two adjacent pushing parts 133 is greater than the width of the elastic cord 20.

[0040] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 10 and Figure 11, the automatic bundling and packaging machine for circuit boards further includes a placement frame 141, a fixed cylinder 143, a limiting rod 144, a U-shaped rod 146, and a driving assembly. At the top of the left ends of the two placement plates 2, a placement frame 141 for placing the elastic cord 20 is fixedly connected. An opening 142 is formed on the right side of the bottom of the placement frame 141. On the left side of the top of the placement frame 141, two fixed cylinders 143 are fixedly connected. Limiting rods 144 with inclined surfaces II 145 at the bottom ends are inserted into the fixed cylinders 143. The limiting rods 144 extend into the placement frame 141. The distance between the bottom end of the limiting rod 144 and the inner bottom of the placement frame 141 only allows one elastic cord 20 to pass through. The distance between the left side of the limiting rod 144 and the inner left wall of the placement frame 141 only allows one elastic cord 20 to pass through. When the synchronous belt 132 rotates, the pushing part 133 passes through the bottom of the placement frame 141. On the lower parts of the left and right sides of the placement frame 141, a pair of U-shaped rods 146 are slidably connected. Both ends of the U-shaped rod 146 have limiting ends 147, and the end faces of the limiting ends 147 are inclined. In each pair of U-shaped rods 146, the limiting ends 147 of the two U-shaped rods 146 alternately extend into the interior of the placement frame 141. A driving assembly for sliding the U-shaped rod 146 is provided on the placement frame 141.

[0041] Reference Figure 10 , Figure 12 and Figure 13 , the driving assembly includes a fixed block 151, a rotating plate 152, a round block 154, a lifting block 155, and a hinged rod 156. Fixed blocks 151 are connected to the lower parts of the left and right sides of the placement frame 141. Rotating plates 152 are rotatably connected to the fixed blocks 151. Long holes 153 are formed at both ends of the rotating plate 152. Round blocks 154 are rotatably connected to the front parts of the U-shaped rods 146. The four round blocks 154 are respectively located in the four long holes 153. In front of the placement frame 141, two lifting blocks 155 driven by electric push rods five are provided. Hinged rods 156 are rotatably connected between the two lifting blocks 155 and the two upper round blocks 154 respectively.

[0042] Put a plurality of elastic ropes 20 into the placement frame 141 in sequence, and then insert the limiting rod 144 into the fixed cylinder 143. There is exactly one elastic rope 20 located below the limiting rod 144, while the left parts of the remaining elastic ropes 20 are located between the left side of the limiting rod 144 and the left inner wall of the placement frame 141. Under the action of gravity, the right half of the lowermost elastic rope 20 passes through the opening 142 and falls to a position flush with the pushing part 133. The limiting ends 147 of the two lower U-shaped rods 146 extend into the interior of the placement frame 141 to support the remaining elastic ropes 20. At this time, control the driving motor to drive the driving roller 131 to rotate, drive the synchronous belt 132 to rotate clockwise, and the pushing part 133 will contact the right half of the lowermost elastic rope 20. Under the guiding action of the second inclined surface 145, the pushing part 133 smoothly pushes the lowermost elastic rope 20 to move rightward above the four first inclined holes 21. With the cooperation of the limiting rod 144 and the U-shaped rod 146, the remaining elastic ropes 20 can be limited.

[0043] Control the fifth electric push rod to drive the lifting block 155 to translate upward. Under the transmission action of the hinge rod 156, the hinge rod 156 pulls the two upper round blocks 154 to approach each other in the left-right direction, driving the two upper U-shaped rods 146 to approach each other. Since the four round blocks 154 are respectively located in the four long holes 153, the two upper round blocks 154 that approach each other can make the two rotating plates 152 rotate, thereby driving the two lower round blocks 154 to move away from each other, causing the two lower U-shaped rods 146 to move away from each other. The specific state after the U-shaped rod 146 slides is as Figure 13 shown; at this time, the lowermost elastic rope 20 in the placement frame 141 falls below the limiting rod 144. Control the fifth electric push rod to drive the lifting block 155 to translate downward to reset. Conversely, the U-shaped rod 146 resets to the Figure 12 initial state shown. The remaining elastic ropes 20 are supported by the two lower U-shaped rods 146. In this way, the pushing part 133 can automatically push the elastic ropes 20 in the placement frame 141 to the four first inclined holes 21 one by one. The pushing and bundling processes of the elastic ropes 20 are closely coordinated, further improving the degree of automation and work efficiency.
