Description

Technical Field

[0001] The invention relates to the technical field of capacitor production and transportation, and in particular to a conveying device for a capacitor stainless steel shell production line. Background Art

[0002] Capacitors are electronic components that can store charge and electrical energy. They are usually composed of two conductors close to each other with a layer of non-conductive insulating medium sandwiched between them. Capacitors play an important role in circuits and are widely used in tuning, bypassing, coupling, filtering, etc. The outer shell of a capacitor generally has two types: plastic insulating shell and stainless steel shell. Stainless steel shell has been widely used due to its strong pressure resistance, non-deformation, long service life, corrosion resistance and other advantages. The existing capacitor stainless steel shell will use conveying devices in the stamping, shaping, assembly, painting and other production processes to ensure that the stainless steel shell can be accurately positioned and accurately transported to the processing area to form an automated production line.

[0003] The existing capacitor stainless steel shell conveying device has many technical defects when in use. First, when the shell workpiece on the conveying device is transferred to the positioning seat of the paint spraying mechanism or the pressing mechanism, the shell workpiece is prone to tipping over and the positioning position is inaccurate, and manual assistance is required for positioning, which is time-consuming and labor-intensive, and has low work efficiency; second, after the conveyor belt has been used for a long time, dust and stains will accumulate on the surface, and the viscosity will increase, thereby interfering with the normal transportation of the shell workpiece and contaminating the outer surface of the shell workpiece; third, a tensioner is currently installed on the transmission chain of the conveying device to tension the transmission chain to prevent it from loosening and reducing the transmission efficiency. However, the tensioning spring on the tensioner will increase with the increase of use time, the material fatigue will increase, and the elasticity will weaken. Therefore, the spring must be replaced regularly, which is time-consuming and labor-intensive, and increases the cost of use.

[0004] In summary, considering that the existing facilities cannot meet the work requirements, we propose a conveying device for the capacitor stainless steel shell production line. Summary of the invention

[0023] The present invention provides a conveying device for a capacitor stainless steel shell production line through improvement, which has the following significant improvements and advantages compared with the prior art: When the first wheel shaft moves, the No. 1 change gear is caused to follow, and after the No. 1 change gear and the No. 2 change gear are meshed and changed direction, the second synchronous sprocket coaxial with the No. 2 change gear is caused to rotate, thereby causing the first wheel shaft on the first synchronous sprocket to rotate through the synchronous and same-direction transmission of the second synchronous sprocket, and through the connection transmission action of the second sprocket and the second chain, a plurality of groups of automatic material pickers on the second chain are driven to perform rotary motion, share a power source, and achieve the purpose of energy saving and cost reduction. An automatic material picker is designed, and the shell part enters the U-shaped positioning groove and is restricted in position. When the automatic material picker is moving at the lower end of the second chain, the telescopic rod on the elastic clamping structure will enter the pressure track from the transition surface, and the telescopic rod will be pressed back for a distance, and the outer surface of the shell part will be contacted by the elastic steel clip. The two sets of elastic steel clips are bent and clamp the shell part at the same time, thereby achieving the effect of automatic clamping, and continue to move to the top of the positioning seat of the paint spraying mechanism. At this time, the telescopic rod just passes through the transition surface from the inside of the pressure track to the outside of the pressure track. In this process, the telescopic rod loses its restraint and immediately moves outward under the elastic force of the reset spring, separating the elastic steel clip and the shell part. The shell part loses its clamping effect and makes a limited linear motion downward along the U-shaped positioning groove, just falling on the positioning seat, thereby achieving the effect of automatic positioning and unloading. No manual assistance is required, and it is suitable for automated production lines. When the conveyor belt moves, its bottom will always be in contact with the friction rubber roller. The friction force generated by the two causes the friction rubber roller to move. During the rotation process, the friction rubber roller will wipe off the dust and stains on the conveyor belt, thereby achieving the purpose of automatic cleaning and solving the pollution problem of the conveying device. At the same time, it causes the large gear to rotate, and the large gear causes the small gear to accelerate after meshing, driving the brush shaft to rotate. Several groups of cleaning bristles on it make circular motion, first extending downward into the liquid storage tank to dip a small amount of cleaning liquid, and then moving upward to contact the surface of the friction rubber roller, using the cleaning liquid to clean the stains on the surface of the friction rubber roller, maintaining the cleanliness of the friction rubber roller, and having a high degree of automation. When the elasticity of the tensioning spring weakens, a downward pressure force is applied to the sleeve by turning the adjusting nut, causing the sleeve to drop along the outer casing, and compressing the tensioning spring between the sleeve and several groups of spring positioning rods by a certain distance, thereby increasing the elastic force of the tensioning spring in the initial position, further acting downward on the tensioning gear, maintaining the degree of downward pressure on the tensioning gear, thereby offsetting the impact of the weakened elasticity. Compared with directly replacing the spring, it is more convenient and saves cost. BRIEF DESCRIPTION OF THE DRAWINGS

The four groups of first sprockets 10 are respectively sleeved on two groups of first wheel axles 11. Both ends of the first wheel axle 11 are fixed by a first bearing seat 12 and the side baffles 2. The two groups of first sprockets 10 on the same side are connected and driven by a first chain 13.

[0028] The two groups of first chains 13 are surrounded by a conveyor belt 14, which is used to transport the shell member 3 (the shell member 3 is vertically placed on the conveyor belt 14). A shaping seat 15 is provided in the middle of the conveyor belt 14, and the two side surfaces of the shaping seat 15 are riveted to the inner wall of the side baffle 2 through a connecting plate 16, such as Figure 1 , Figure 3 , Fig.12 shown.

[0029] Among them, the end of a group of first wheel shafts 11 extends outwardly and is sleeved with a dividing wheel 17. Four groups of strip grooves 18 and arc guide grooves 19 are evenly distributed on the wheel surface of the dividing wheel 17. The strip grooves 18 and the arc guide grooves 19 are alternately distributed in sequence.

The guide platform 85 and the arc guide groove 19 are fully fitted during the movement to play a guiding role. A driving column 86 that interacts with the strip groove 18 is welded at the edge of the curved surface and the end of the crank disk 83, and the thickness of the driving column 86 is adapted to the width of the strip groove 18.

[0032] Further, an outer bracket 4 is installed at the right end of each set of side baffles 2, and the outer bracket 4 plays the role of limiting support. The left end of the outer bracket 4 is located above the positioning seat of the paint spraying mechanism. The two sets of outer brackets 4 are symmetrically provided with two sets of second axles 20. Both ends of the second axles 20 are fixed by the second bearing seat and the outer bracket 4. Two sets of second sprockets 21 are symmetrically sleeved on each set of second axles 20. The two sets of second sprockets 21 on the same side are connected and driven by the second chain 22. Figure 1 , Figure 2 , Figure 5 and Figure 6 shown.

[0033] The second wheel axle 20 at the left position passes through the outer bracket 4 and is sleeved with the first synchronous sprocket 23. Figure 5 and Figure 6 shown.

[0034] Furthermore, a first direction-changing gear 24 is sleeved on one end of the first wheel shaft 11 away from the indexing wheel 17, and a second direction-changing gear 25 is meshedly arranged on one side of the first direction-changing gear 24. The first direction-changing gear 24 and the second direction-changing gear 25 have the same size, and the second direction-changing gear 25 is sleeved on the outer positioning shaft 26. The end of the outer positioning shaft 26 is fixed by a third bearing seat 27 and the outer wall of the outer bracket 4, as shown in FIG. Figure 3 , Figure 5 and Figure 6 shown.

[0035] Furthermore, a second synchronous sprocket 28 is sleeved on the outer positioning shaft 26, and the second synchronous sprocket 28 and the first synchronous sprocket 23 are connected and driven by a synchronous outer chain 29. The first synchronous sprocket 23 and the second synchronous sprocket 28 have the same size. Figure 5 and Figure 6 shown.

[0036] Among them, a plurality of groups of automatic material pickers 30 acting on the housing 3 are evenly distributed on the two groups of second chains 22, such as Figure 1 , Figure 5 and Figure 6 shown.

[0037] Specifically, the automatic material picker 30 includes a U-shaped material picker seat 31, a welding piece 32, a U-shaped positioning groove 33, a limiting opening 34 and an elastic clamping structure 35. Figure 7 shown.

[0038] In this embodiment, the upper end surface of the U-shaped material picking seat 31 is connected to the two groups of second chains 22 through two groups of welding plates 32 respectively, the U-shaped material picking seat 31 is in a horizontal state, and a U-shaped positioning groove 33 adapted to the shell member 3 is opened inside the U-shaped material picking seat 31 (the U-shaped material picking seat 31 covers the upper half of the shell member 3), the U-shaped positioning groove 33 is semi-open design, and two groups of limit openings 34 are symmetrically opened on the groove wall of the U-shaped positioning groove 33, and an elastic clamping structure 35 is installed in each group of limit openings 34.

[0039] Furthermore, the elastic clamping structure 35 includes a telescopic rod 351, a slider 352, a clamping block 353, a return spring 354 and an elastic steel clip 355. Figure 8 shown.

[0040] In this embodiment, a rod groove is opened outwardly inside the U-shaped material picking seat 31, and a telescopic rod 351 is movably arranged in the rod groove. The rod groove serves as a storage guide, and a slider 352 is installed at the position where the telescopic rod 351 extends out of the rod groove. Pressure tracks 71 are horizontally installed on the inner walls of the two groups of outer brackets 4. The pressure track 71 provides linear motion for the telescopic rod 351. Transition surfaces 72 that interact with the slider 352 are provided at both ends of the pressure track 71. When the two groups of telescopic rods 351 on the U-shaped material picking seat 31 are respectively located on the pressure tracks 71, the U-shaped material picking seat 31 is limited, thereby improving the stability of the linear motion of the U-shaped material picking seat 31.

[0041] In this embodiment, a clamp block 353 is welded to one end of the telescopic rod 351 away from the slider 352. The clamp block 353 is located in the limit opening 34. The two are matched in size and serve as a limit guide. An elastic steel clip 355 acting on the outer surface of the shell member 3 is welded to the end of the clamp block 353. The elastic steel clip 355 is made of spring steel and has the ability to reset after deformation.

[0042] Furthermore, a cleaning box 40 is riveted to the left end of the device base 1 and is located below the conveyor belt 14. A cleaning groove 41 is opened upward inside the cleaning box 40. A friction rubber roller 42 is rotatably arranged in the cleaning groove 41. A part of the friction rubber roller 42 extends out of the cleaning groove 41 and contacts the bottom surface of the conveyor belt 14. There is a strong friction force between the two. Figure 1 and Fig. 9 shown.

[0043] Among them, the two ends of the friction rubber roller 42 are symmetrically welded with shafts 43, and the outer sleeve of the shaft 43 is connected with a first inner bearing 44 fixed to the inner wall of the cleaning box 40. The interior of the cleaning box 40 and the two sides of the cleaning slot 41 are symmetrically provided with transmission slots 45, and the shafts 43 extend into the transmission slots 45. A large gear 46 is sleeved on one set of the shafts 43, and the large gear 46 is designed to be a light and thin structure, such as Fig. 9 and Fig.10 shown.

[0044] The cleaning tank 41 is connected to a liquid storage tank 47 below, in which cleaning liquid is stored. A brush shaft 50 is rotatably arranged above the liquid storage tank 47 and inside the cleaning tank 41. The two ends of the brush shaft 50 are fixed by a second inner bearing 51 and the inner wall of the cleaning box 40. Fig.10 and Fig.11 shown.

[0045] Furthermore, a small gear 52 is sleeved at the position where the brush shaft 50 extends into the transmission groove 45. The small gear 52 is designed to be a light and thin structure. The small gear 52 is meshed with the large gear 46. Fig.10 and Fig.11 shown.

[0046] Among them, a plurality of groups of small brush holders 53 are evenly distributed on the brush shaft 50, and each group of small brush holders 53 is connected to a plurality of groups of cleaning bristles 54 in contact with the friction rubber roller 42, such as Fig.11 shown.

[0047] A drain pipe 73 is installed at the lower left end of the cleaning box 40, and a liquid guide port 74 connected to the drain pipe 73 is provided on the wall of the liquid storage tank 47. A solenoid valve is installed in the drain pipe 73 to discharge sewage regularly. Fig. 9 and Fig.10 shown.

[0048] Furthermore, an interceptor 70 is movably provided between the two sets of side baffles 2 and above the conveyor belt 14. The interceptor 70 is a hydraulic structure. The interceptor 70 is used to intercept the housing member 3 moving on the conveyor belt 14 and to correct the initial position of the housing member 3. Figure 2 shown.

[0049] When the present embodiment is in use, the shell parts 3 to be transported are sequentially placed in the upper left position of the conveyor belt 14, and the servo motor 81 is started, and the rotating shaft 82 drives the crank plate 83 to rotate one circle, causing the driving column 86 to make a circular motion. During the movement, the driving column 86 enters the strip groove 18 of one group of dividing wheels 17, and the relative force generated by the two causes the dividing wheels 17 to rotate until the driving column 86 moves out of the strip groove 18. At this time, the dividing wheel 17 drives the first wheel shaft 11 to rotate 90°, and the transmission of the first sprocket 10 and the first chain 13 causes the conveyor belt 14 to move linearly, and the conveyor belt 14 drives the shell part 3 to move one grid to the right (that is, one quarter of the circumference of the first sprocket 10), and the cyclic transmission causes the shell part 3 to realize stepping motion until the shell part 3 encounters the interception of the interceptor 70 and stops moving. After correcting the initial position, the interceptor 70 is lifted to make the shell part 3 continue to make stepping motion to the right.

[0050] When the first wheel shaft 11 moves, the first direction-changing gear 24 is caused to follow (rotate clockwise). After the first direction-changing gear 24 and the second direction-changing gear 25 are meshed and changed direction, the second synchronous sprocket 28 coaxial with the second direction-changing gear 25 is caused to rotate (rotate counterclockwise), thereby causing the first wheel shaft 11 on the first synchronous sprocket 23 to rotate through the synchronous and same-direction transmission of the second synchronous sprocket 28, and through the connection transmission action of the second sprocket 21 and the second chain 22, the multiple groups of automatic material pickers 30 on the second chain 22 are driven to perform rotational motion.

[0051] One group of automatic material pickers 30 moves from the upper end of the second chain 22 to the lower end of the second chain 22, and contacts the shell member 3 on the conveyor belt 14 (the stepping speed of the shell member 3 is not greater than the stepping speed of the automatic material picker 30). The shell member 3 enters the U-shaped positioning groove 33 and is restricted in position, and moves to the right with the automatic material picker 30. When the automatic material picker 30 is at the lower end of the second chain 22, the telescopic rod 351 on the elastic clamping structure 35 will enter the pressure track 71 from the transition surface 72. During this process, the telescopic rod 351 is pressed back a certain distance (the return spring 354 is compressed), so that the clamping block 353 moves outward from the limit opening 34, thereby using the elastic steel clip 355 to contact the outer surface of the shell member 3 (a micro-displacement process). The elastic steel clips 355 on the two groups of elastic clamping structures 35 act on the shell member 3 in opposite directions at the same time. 55 is bent and the shell part 3 is clamped at the same time. The automatic material picker 30 carries the shell part 3 away from the right end of the conveyor belt 14 (at this time, the telescopic rod 351 is in the pressure track 71, and the shell part 3 is still in a clamped state), and then continues to move to the top of the positioning seat of the paint spraying mechanism. At this time, the telescopic rod 351 just passes through the transition curved surface 72 from the pressure track 71 to the outside of the pressure track 71. In this process, the telescopic rod 351 loses its restraint and immediately moves outward under the elastic force of the reset spring 354. The clamping block 353 is recovered, thereby separating the elastic steel clip 355 from the shell part 3. The shell part 3 loses its clamping effect and makes a limited linear motion downward along the U-shaped positioning groove 33, just falling on the positioning seat, achieving the effect of automatic unloading. Then the automatic material picker 30 rotates upward from the lower end of the second chain 22 to the upper end of the second chain 22, and works in this cycle.

[0052] When the conveyor belt 14 moves, its bottom will always be in contact with the friction rubber roller 42, and the friction force generated by the two will cause the friction rubber roller 42 to move. During the rotation, the friction rubber roller 42 will wipe off the dust and stains on the conveyor belt 14 (part of the dust and stains are transferred to the friction rubber roller 42, and part of them fall downward into the cleaning groove 41), and at the same time cause the large gear 46 to rotate. The large gear 46 causes the small gear 52 to accelerate after meshing, and drives the brush shaft 50 to rotate. When the brush shaft 50 rotates, several groups of cleaning bristles 54 thereon make circular motions, first extend downward into the liquid storage groove 47 to dip a small amount of cleaning liquid, and then move upward to contact the surface of the friction rubber roller 42, and use the cleaning liquid to clean the stains on the surface of the friction rubber roller 42 to maintain the cleanliness of the friction rubber roller 42.

[0053] Embodiment 2: Based on embodiment 1, currently, a tensioner is installed on the transmission chain of the conveying device to tension the transmission chain to prevent it from loosening and reducing the transmission efficiency. However, the tension spring on the tensioner will increase material fatigue and weaken elasticity as the use time increases. Therefore, the spring must be replaced regularly, which is time-consuming and labor-intensive and increases the use cost. In order to solve the above technical problems, we have the following design, such as Figure 12-14 shown.

[0054] Specifically, an inner groove 60 is provided at the middle position of both sides of the shaping seat 15, and an annular outer positioning seat 61 is provided in the inner groove 60. The annular outer positioning seat 61 is fixed to the groove wall of the inner groove 60 by a plurality of groups of connecting pieces 62, such as Fig.12 and Fig.13 shown.

[0055] Among them, the annular outer positioning seat 61 is provided with a through hole 63 from top to bottom, a loose adjuster 9 is installed in the through hole 63, the lower end of the loose adjuster 9 is connected to a wheel frame 64, and a tensioning gear 65 meshing with the inner surface of the first chain 13 is rotatably arranged in the wheel frame 64, such as Fig.13 shown.

[0056] Specifically, the loose adjuster 9 includes an outer sleeve 91, a fixing block 92, an inner sleeve groove 93, a connecting column 94, a spring positioning rod 95 and an adjusting groove 96. Fig.14 shown.

[0057] In this embodiment, the lower end of the outer casing 91 is fixed by a plurality of groups of fixing blocks 92 and the inner wall of the through opening 63. An inner tube groove 93 is downwardly opened inside the outer casing 91. A connecting column 94 is movably provided inside the inner tube groove 93. The connecting column 94 moves up and down in the inner tube groove 93. A wheel frame 64 is fixedly provided at the lower end of the connecting column 94.

[0058] In this embodiment, a plurality of groups of spring positioning rods 95 are evenly welded around the outer cylindrical surface of the connecting column 94, and an adjustment groove 96 connected to the inner cylinder groove 93 is opened on the outer side surface of the outer casing 91. Each group of adjustment grooves 96 is for the corresponding spring positioning rod 95 to pass through. The spring positioning rod 95 moves up and down in the adjustment groove 96, and the thickness of the spring positioning rod 95 is adapted to the width of the adjustment groove 96.

[0059] Furthermore, the loosening regulator 9 also includes a threaded portion 97, an adjusting nut 98, a sliding sleeve 99, a tensioning spring 910, an L-shaped sliding block 911 and a sliding guide groove 912. Fig.14 shown.

[0060] In this embodiment, a threaded portion 97 extending out of the through opening 63 is provided at the upper end of the outer casing 91, and an adjusting nut 98 is screwed on the threaded portion 97. The lower end of the adjusting nut 98 is in contact with a sliding sleeve 99 sleeved on the outer casing 91. The sliding sleeve 99 is in sliding contact with the outer side surface of the outer casing 91, and a tensioning spring 910 sleeved on the outer casing 91 is fixed between the sliding sleeve 99 and a plurality of groups of spring positioning rods 95.

[0061] In this embodiment, a plurality of groups of L-shaped sliding blocks 911 are evenly fixed around the lower edge of the sliding sleeve 99, and the outer surface of the outer casing 91 is provided with sliding guide grooves 912 for the corresponding L-shaped sliding blocks 911 to move, which play a guiding and limiting role to prevent the sliding sleeve 99 from axial movement.

[0062] When the present embodiment is in use, the downward force exerted by the tensioning gear 65 on the first chain 13 is utilized to ensure that the first chain 13 has a certain tension during movement. When the elasticity of the tensioning spring 910 weakens, a downward force is exerted on the sliding sleeve 99 by screwing the adjusting nut 98, so that the position of the sliding sleeve 99 is lowered along the outer casing 91 (a plurality of groups of L-shaped sliding blocks 911 slide downward along the sliding guide grooves 912 respectively), so that the tensioning spring 910 between the sliding sleeve 99 and a plurality of groups of spring positioning rods 95 is compressed for a certain distance, thereby increasing the elastic force of the initial position of the tensioning spring 910, and further acting downward on the connecting column 94, the wheel frame 64 and the tensioning gear 65 in turn, maintaining the downward pressure of the tensioning gear 65, thereby offsetting the effect of the weakened elasticity.
