Description

Technical Field

[0001] The invention relates to the field of material conveying, and in particular to a portable copper ball conveying device for circuit board electroplating. Background Art

[0002] In the electroplating process of circuit boards, there is a process of copper plating the circuit boards. After the circuit boards enter the copper plating pool, they move slowly in the copper plating pool to complete the copper plating. In the copper plating pool, a group of storage bins are set up in the pool at each interval. The function of the storage bins is to store the metal copper required for copper plating. The copper balls are pre-stored in the storage bins. The copper balls in the storage bins will be gradually consumed during the electroplating process. Therefore, workers are required to check the copper balls in the storage bins at various positions in the copper plating pool from time to time. If there are deficiencies, copper balls need to be added to the storage bins. Since the storage bins in the middle part of the copper plating pool are far away from the pool bank, there is a risk of falling when workers put copper balls into the storage bins far away from the pool bank. In addition, the copper balls themselves have a certain weight. Repeated long-term and long-distance copper balls may fall on the way, and accurate placement cannot be achieved. The placement operation is inconvenient and has certain risks. Summary of the invention

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The present invention specifically discloses a portable copper ball conveying device for circuit board electroplating, such as Figure 1-Figure 12 As shown, it includes: a storage box 11 for storing supplementary materials, the copper balls to be supplemented are placed in the storage box 11, and wheels are arranged at the bottom of the storage box 11. After being filled with copper balls, the storage box 11 can be moved by pulling the handle 13 installed on the side wall of the storage box 11. A discharge port 14 is opened at the bottom of the storage box 11 near the corner to allow the copper balls to enter and exit. The copper balls in the storage box 11 are discharged through this discharge port 14. In order to better guide the copper balls in the storage box 11 to gather toward the discharge port 14, refer to Figure 3 and Figure 4 As shown, an inclined base 15 is provided at the bottom of the containing box 11 to guide the materials to roll and gather toward the discharge port 14. A high end surface 151 with the highest plane is provided on the inclined base 15, and a bottom end surface 152 with the lowest plane is provided at the other end diagonally opposite the high end surface 151. The top plane of the inclined base 15 is inclined toward the bottom end surface 152 as a whole, so that the spherical materials falling on the inclined base 15 will spontaneously roll toward the bottom end surface 152, and the position where they roll to the bottom end surface 152 is the position of the discharge port 14. Therefore, through the inclined base 15, the copper balls can be better gathered toward the discharge port 14.

[0036] Reference Figure 1 and Figure 6As shown, the discharge port 14 is connected with an annular guide tube 16 through a three-way joint, and the annular guide tube 16 is connected end to end. After the copper ball comes out of the discharge port 14, it will enter the annular guide tube 16. Three guide channels 161 are provided on the outer wall of the annular guide tube 16, and an isolation conveying chain is slidably provided in the annular guide tube 16. The isolation conveying chain is also connected end to end and arranged in the annular guide tube 16, and the isolation conveying chain is slidably arranged in the annular guide tube 16 through the guide channels 161. The copper balls entering the annular guide tube 16 are separated one by one by the chain spacing of the isolation conveying chain and stored in the annular guide tube 16. A handle 17 is fixedly installed on the annular guide tube 16, and a hand-cranked pushing device 18 is installed on the handle 17. The function of the hand-cranked pushing device 18 is to push the isolation conveying chain to slide in the annular guide tube 16, so that each copper ball entering the annular guide tube 16 can be pushed into the annular guide tube 16. The copper balls in the tube 16 can all be separated by the isolating conveyor chain, and as the hand-cranked pushing device 18 works, the copper balls will slowly approach the position of the hand-cranked pushing device 18, and a discharge pipe 19 is also connected to the annular guide tube 16 through a three-way joint. The position of the discharge pipe 19 is adjacent to the position of the hand-cranked pushing device 18, and the copper balls are blocked by the isolating conveyor chain. During the movement of the isolating conveyor chain, the copper balls will be transferred to the three-way joint connection position connected to the discharge pipe 19. Therefore, when the copper balls encounter the three-way joint connection at this position, the copper balls will roll toward the discharge pipe 19. Therefore, when in use, only one hand is needed to hold the handle 17 to adjust the direction of the discharge pipe 19, and the other hand is used to operate the hand-cranked pushing device 18 to push the copper balls from the containing box 11 to the discharge pipe 19, and finally the copper balls are discharged from the discharge pipe 19 and fall into the designated position.

[0037] The present invention guides the spherical materials to gather at one place through the inclined base 15, so that the spherical materials enter the annular guide pipe 16, and the isolation conveying chain arranged in the annular guide pipe 16 can separate the spherical materials entering the annular guide pipe 16, and push the spheres one by one from the annular guide pipe 16 to the discharge pipe 19 under the action of the hand-cranked pushing device 18. After the pipe mouth of the discharge pipe 19 is moved to the specified position, the spherical materials can fall into the specified position. In this way, when filling materials, workers do not need to lean out to deliver the materials to the specified storage bin. The use is simple and convenient, and the delivery is accurate and safe. The materials can be directly delivered from the containing box 11 to the storage bin.

[0038] Reference Figure 2 and Figure 3As shown, partition plates 12 are evenly spaced in the containing box 11. When the copper balls are piled up in the containing box 11 without being separated, the copper balls are piled up against each other and are likely to be stuck in the containing box 11, so that the copper balls cannot enter the annular guide tube 16 from the discharge port 14 at the bottom. The partition plates 12 can be used to divide the copper balls into areas, so that the copper balls can fall down in an orderly manner without getting stuck.

[0039] Reference Figure 3 and Figure 5 As shown, the partition plate 12 is installed in the storage box 11 in a movable plug-in manner. In order to ensure the stable connection between the partition plate 12 and the storage box 11, the side walls on both sides of the storage box 11 are evenly spaced with bite grooves 111, and the partition plate 12 is provided with protruding teeth 121 that fit with the bite grooves 111. The partition plate 12 is slidably installed in the bite grooves 111 through the protruding teeth 121, thereby achieving a stable connection effect. When the copper balls in a partition plate 12 are consumed, the partition plate 12 can be pulled up to make the other part of the copper balls fall to the bottom. It can be imagined that a vibration device can be installed in the inclined base 15. The vibration device can be a vibration motor. Through the provided vibration device, the copper balls that fall on the inclined base 15 can always have a tendency to roll toward the discharge port 14, so as to ensure that the copper balls will not get stuck near the discharge port 14.

[0040] Reference Figure 6-Figure 8 As shown, the isolation conveying chain includes: a traction rope 162 installed in a guide channel 161, on which sliding balls 163 are evenly fixedly installed, and the sliding balls 163 are placed in the guide channel 161 and can slide in the guide channel 161. The sliding balls 163 at the same height are commonly connected with isolation blocks 164. After the copper balls come out of the discharge port 14, they will fall on the isolation blocks 164. When the traction rope 162 moves the copper balls on the isolation blocks 164 up one position, the subsequent copper balls will fall on the next isolation blocks 164, and so on, so that the copper balls can move in an orderly manner in the annular guide tube 16 and finally reach the designated position.

[0041] The end faces of both ends of the isolation block 164 are provided with inwardly recessed groove surfaces 165, through which the stable contact with the copper ball can be maintained; the annular guide tubes 16 connected end to end are in contact with each other and brought together through the constraint blocks 166, so that the annular guide tubes 16 will not affect the use.

[0042] Reference Figure 6 , Fig. 9 and Fig.10As shown, the hand-cranked pushing device 18 comprises: a mounting shell 181 mounted on the handle 17, an annular guide tube 16 is connected around the edge of the mounting shell 181 and maintained in a fixed state, sprockets 182 are rotatably arranged on both sides of the mounting shell 181, a chain 183 is wound around the sprocket 182, a pushing block 184 is evenly installed on the chain 183 according to the spacing of the sliding ball 163, a notch is opened on the annular guide tube 16 to allow the pushing block 184 to enter, and a gap is provided on the pushing block 184, so that the pushing block 184 can be pushed into the handle 17. After the moving block 184 is placed in the annular guide tube 16, the traction rope 162 is placed in the gap, so after the pushing block 184 moves, it will abut against the sliding ball 163 and push the sliding ball 163 to move, thereby pulling the traction rope 162 to move. The crank 185 is installed on one of the sprockets 182 to rotate the sprocket 182. When in use, it is only necessary to shake the crank 185 to move the chain 183 with the pushing block 184, thereby making the traction rope 162 move in a circle in the annular guide tube 16.

[0043] Reference Fig.10 As shown, the push block 184 has two intercepting parts 1841 separated from each other, the gap between the two intercepting parts 1841 allows the traction rope 162 to be placed, and the side of the intercepting part 1841 that contacts the sliding ball 163 is provided with a concave curved groove 1842, and the intercepting part 1841 contacts the sliding ball 163 through the curved groove 1842. During the movement of the push block 184, the intercepting part 1841 can be against the surface of the sliding ball 163, and during the process of pushing the sliding ball 163, the concave curved groove 1842 will not easily cause the sliding ball 163 to fall off the intercepting part 1841.

[0044] Reference Fig.11 As shown, it also includes: a ratchet ring 1861 fixedly mounted on the outer surface of the mounting shell 181, a turntable 1862 coaxially connected to one of the sprockets 182, and the turntable 1862 is in the ratchet ring 1861, and a pawl 1863 is hingedly mounted at an eccentric position of the turntable 1862, and the pawl 1863 is kept against the ratchet ring 1861 by a torsion spring, and a top cover 1864 is installed on the ratchet ring 1861 to cover the turntable 1862. The sprocket 182 is rotated by the crank 185 to move the traction rope 162. At this time, the crank 185 rotates clockwise, and the pawl 1863 slides along the inner wall of the ratchet ring 1861. When the isolation conveyor chain at the rear is too heavy and causes the isolation conveyor chain to slide backward as a whole, the crank 185 will rotate counterclockwise. However, due to the existence of the ratchet ring 1861, the pawl 1863 rests on the reverse teeth of the ratchet ring 1861, thereby preventing the crank 185 from rotating counterclockwise, thereby preventing the isolation conveyor chain from sliding backward, thereby achieving an anti-reverse locking effect.

[0045] Reference Fig.12As shown, it also includes: a sleeve frame 21 installed at the end of the discharge pipe 19, an L-shaped plate 22 hingedly installed on the sleeve frame 21, and a thickened contact portion 24 is provided at the end of the extension plate 23. The extension plate 23 is in a curved shape as a whole, and the extension plate 23 is fixedly installed on the L-shaped plate 22 through the contact portion 24. When not in use, the extension plate 23 is folded and turned to keep it flush with the discharge pipe 19. When the delivery distance of the copper ball is too far and the length of the discharge pipe 19 is not enough to reach it, the extension plate 23 can be turned over so that the contact portion 24 and the sleeve frame 21 are against each other, and the copper ball coming out of the discharge pipe 19 will continue to roll with the help of the extension plate 23 until it reaches the specified position. The delivery distance can be increased by the extension plate 23 to meet the use requirements.

[0046] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
