Description

Technical Field

[0001] The present invention relates to an improved invention for battery packaging equipment, and in particular to a feeding mechanism of a battery packaging machine. Background Art

[0002] The battery packaging machine uses a special belt conveyor, see attached Figure 1 The conveying surface of the conveyor belt is provided with arc-shaped grooves B that match the batteries. The batteries are placed in the grooves. The spacing between adjacent batteries is consistent with the spacing when adding materials. Therefore, the arc-shaped grooves on the conveyor belt are very dense.

[0003] The size specifications of No. 5 batteries and No. 7 batteries are different. The corresponding grooves for No. 5 batteries are larger, and the corresponding grooves for No. 7 batteries are smaller. The corresponding conveyor belts need to be replaced according to different types of batteries. If the conveyor belt used to convey No. 5 batteries is used to convey No. 7 batteries, then the No. 7 batteries will shake on the conveyor belt, resulting in inaccurate feeding position, and the spacing between batteries is too large, and they cannot be fed directly. On the contrary, if No. 5 batteries are placed on the conveyor belt used to convey No. 7 batteries, the grooves are too small and too dense, and two batteries cannot be placed in adjacent grooves. Therefore, a matching conveyor belt needs to be replaced. Replacing the conveyor belt is not only labor-intensive and time-consuming, affecting production efficiency, but also has high processing costs for special conveyor belts. Summary of the Invention

[0004] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a universal feeding mechanism for a battery packaging machine, which is easy to operate and highly practical.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: the feeding mechanism of the battery packaging machine is characterized in that it includes:

[0006] A conveyor belt having strip-shaped grooves on its conveying surface, the grooves being arranged transversely and evenly arranged longitudinally, with bosses between adjacent grooves, and the distance between the center lines of two adjacent bosses being no less than the outer diameter of the material;

[0007] A variable-distance material guide assembly includes a material guide plate, which is laterally arranged on one side of the conveyor belt. The material guide plate is provided with a material guide trough, and the feed end of the material guide trough is connected to the discharge station of the conveyor belt;

[0008] A pusher assembly comprising a first push plate movable left and right;

[0009] and a material taking piece that rises and falls, wherein the discharge end of the material guide trough corresponds to the material taking piece of the material taking station.

[0010] The present invention connects the discharging station of the conveyor belt and the picking station of the picking piece through a guide plate. The material is placed in the groove of the conveyor belt. The groove plays a limiting role to separate adjacent materials. When the conveyor belt delivers the material to the discharging station, the first push plate pushes the material on the conveyor belt in the direction of the guide plate, so that the material enters the guide trough and moves the material along the guide trough to the discharging end. The material spacing at the discharging end corresponds to the position of the picking piece. In this way, the picking piece moves down to take out the material from the discharging end. The spacing between adjacent materials on the conveyor belt is greater than the spacing between materials during subsequent packaging. The distance is changed by the guide plate, so that the spacing between adjacent materials at the discharging end is consistent with the spacing during packaging. In this way, the materials taken away by the picking piece do not need to adjust the spacing and can be directly sent into the packaging box.

[0011] Preferably, a plurality of transversely arranged partitions are provided in the material guide trough, and the partitions divide the material guide trough into a plurality of unit guide troughs, and the unit guide troughs correspond to the grooves of the discharge station; one unit guide trough corresponds to one material, so that the materials are more stable when moving and will not interfere with each other.

[0012] Preferably, a baffle is provided at the discharge end of the guide trough; the baffle can prevent the material from escaping from the guide plate and at the same time align the material laterally at the discharge end.

[0013] Preferably, the material picking member is a suction nozzle or a magnet, and the unit guide groove corresponds to the material picking member; the suction nozzle and the magnet are convenient for picking and unloading materials.

[0014] Preferably, the material picking member is mounted on a movable seat, which is connected to a power member 1 that drives it up and down, and the power member 1 is mounted on a first slide, which is connected to a power member 2 that drives it left and right. When picking up materials, the power member 2 drives the material picking member to move to the material picking station, and then the power member 1 drives the material picking member downward to absorb the material at the discharge end, and then the material picking member moves upward, and the power member 2 drives the material picking member to move to the feeding station. After the power member 1 drives the material picking member downward to pick up the material, the power member 2 transports the material picking member to the feeding station, and the material picking member places the material into a blister or packaging box to complete the feeding.

[0015] Preferably, the conveying surface of the conveyor belt is meshed with the driving gear; the conveyor belt adopts single-sided teeth, and the groove of the conveyor belt is used to hold materials and cooperate with the driving gear for transmission, which greatly reduces the processing cost.

[0016] Preferably, the width of the feed end of the guide trough is greater than that of the discharge end, and the discharge end matches the material; the guide trough becomes narrower from wide, which is conducive to the material entering the guide trough, and when the guide trough guides the material to the discharge end, the material matches the guide trough, that is, the radial position is also limited. At this time, the material is fixed in the guide trough and cannot swing. The material corresponds to the picking position of the picking part. When the picking part moves downward, it adsorbs the material, thereby improving the accuracy of picking.

[0017] Preferably, at the discharging station, the feed end of the unit guide trough corresponds to the groove of the conveyor belt to ensure that the material enters the guide trough smoothly.

[0018] Preferably, the pusher assembly further comprises a second push plate, wherein the first push plate and the second push plate are mounted on a push plate seat, wherein the push plate seat is connected to a power member 3 that drives the pusher seat to rise and fall, wherein the power member 3 is mounted on a second slide, and wherein the second slide is connected to a power member 4 that drives the pusher seat to move left and right. The guide trough gradually converges from the feed end to the discharge end, thereby increasing the length of the guide trough and easing the change from the feed end to the discharge end, which is more conducive to the movement of materials in the guide trough. The addition of the second push plate improves the efficiency of pushing materials. After the first push plate pushes the material on the conveyor belt onto the guide plate, the first push plate moves up and resets. When the first push plate pushes the next material on the conveyor belt again, the second push plate pushes the material on the guide plate, and so on until the material is pushed to the discharge end.

[0019] Preferably, the feeding section of the conveyor belt is provided on a support platform, which is mounted on a frame, and a longitudinally arranged magnet is provided below the support platform. When the conveyor belt is feeding, the magnet has an adsorption effect, preventing the batteries from shaking during transportation, thereby further improving the transportation stability.

[0027] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. The X-axis is the horizontal direction, also the left-right direction; the Y-axis is the longitudinal direction, also the front-back direction; and the Z-axis is the vertical direction, also the up-down direction.

[0028] The feeding mechanism of this battery packaging machine includes a conveyor belt 1, a variable-distance material guide component, a material pushing component and a material picking component 8 that rises and falls. The material picking component can be a magnet or a suction nozzle. The magnet can absorb the battery. The suction nozzle is connected to the air source and absorbs the battery through negative pressure. The conveying surface of the conveyor belt 1 is provided with strip grooves 18. The grooves are arranged horizontally and evenly arranged longitudinally. There are bosses 17 between adjacent grooves, and the distance between the center lines 19 of two adjacent bosses is not less than the outer diameter of the material. One groove 18 corresponds to one material. The battery is placed horizontally in the groove, and adjacent materials do not interfere with each other. The conveyor belt 1 of the present invention is suitable for both AA batteries and AA batteries. The specifications of AA batteries are smaller, and the width of the groove can be slightly larger than that of AA batteries. See attached. Figure 3 , the vertical cross-section of the boss 17 is trapezoidal, and the vertical cross-section of the groove is an inverted trapezoid, so that the upper entrance of the groove is large, which is conducive to the entry of materials, and the No. 5 battery is stuck in the groove 18, and the inclined surface is set to increase the contact area between the battery and the groove, and the stability is better; whether it is a No. 5 battery or a No. 7 battery, when placed in the groove on the conveyor belt, the outer diameter of the battery is higher than the height of the groove, that is, part of the battery is outside the groove for pushing the material; the conveyor belt can adopt a standard T20 single-sided tooth transmission belt, so that the conveying surface of the conveyor belt is engaged with the driving gear, which is not drawn in the figure. The conveyor belt is driven by the driving gear. The groove of the conveyor belt is used to hold materials and cooperate with the driving gear for transmission. The use of a standard transmission belt greatly reduces processing costs. In order to further improve the stability of transportation, the feeding section of the conveyor belt is set on the support platform 20, and the conveyor belt is wound on the guide wheel and the driving gear. The two upper guide wheels are set at the same height, and the conveyor belt tooth surface is set upward on the two upper guide wheels 24. The section set on the two upper guide wheels is the feeding section, and the support platform is set between the two upper guide wheels. The support platform 20 is installed on the frame, and a longitudinally arranged magnet 21 is provided under the support platform. The magnet has an adsorption effect to prevent the battery from shaking during transportation.

[0029] The variable distance guide assembly includes a guide plate 4, which is installed on the frame. The guide plate is arranged horizontally on one side of the conveyor belt 1. A guide trough 5 is provided on the guide plate. One or more guide troughs are provided according to the needs. One guide trough corresponds to a group of materials. If multiple groups are fed at the same time, multiple guide troughs are provided on the guide plate. According to the packaging specifications and needs, a group of materials has several, attached Figure 4 and 5 There are four guide troughs in the machine, each of which corresponds to 4 materials. Figure 4 The guide trough in the machine is not divided, and there is no isolation between the materials. Figure 5In the guide trough, there are several transversely arranged partitions 23, which divide the guide trough 5 into 4 unit guide grooves 22. The unit guide grooves correspond to the grooves of the discharge station of the conveyor belt. One unit guide groove corresponds to one material, and the materials do not interfere with each other, and the material movement is more stable. Without partitions, if the feed end is too large, individual batteries will rotate during the movement and change from the original transverse setting to the longitudinal setting, so as not to affect the transportation of other batteries and cause material blockage; the same is that one group of materials corresponds to one package, each group is provided with 4 batteries, 16 batteries are pushed at a time, and four groups are added each time. The guide trough The feeding end 15 is connected with the discharging station of the conveyor belt, and the discharging end 16 of the guide trough corresponds to the picking piece 8 of the picking station. A guide trough corresponds to four grooves. The conveyor belt 1 can be used for the transportation of No. 5 batteries and No. 7 batteries at the same time. The gap between adjacent batteries is large, especially No. 7 batteries. The picking pieces are set according to the packaging specifications. Generally, the arrangement of the picking pieces is relatively compact, and the gap between the batteries is small. Then the guide trough 5 gradually gathers from the feeding end to the discharging end. If the picking pieces 8 are arranged relatively loosely, the gap between the batteries is larger than the battery gap on the conveyor belt, then the guide trough gradually expands from the feeding end to the discharging end. Taking gradual gathering as an example, embodiment 1, see attached Figure 4 , the width of the feed end 15 of the guide trough 5 is greater than the discharge end 16. The guide trough is from wide to narrow. The width of the feed end is conducive to the entry of the material into the guide trough. The width of the feed end is consistent with the width of the four grooves of the corresponding discharge station, so as to ensure that the material enters the guide trough smoothly. The material moves along the guide trough to the discharge end, and the adjacent materials gradually move closer. At the discharge end, the material just corresponds to the material taking piece. For two different types of batteries, AA and AA, or when the number of batteries packaged is different, it is only necessary to replace the guide plate. Compared with replacing the conveyor belt in the background technology, replacing the guide plate is more convenient and quick; Example 2, see attached Figure 5 The feed end of the unit guide trough 22 is wider than the discharge end. The discharge end of the unit guide trough matches the material and has an arc-shaped vertical cross-section. That is, the unit guide trough narrows from wide to narrow. As the material moves along the unit guide trough 22 to the discharge end, the adjacent materials gradually move closer together until the material is aligned with the material removal element at the discharge end. The pusher assembly includes a first push plate 2 that moves left and right. The first push plate is located on the other side of the conveyor belt 1.

[0030] Taking Example 2 as an example, the material is placed in the groove 18, and the groove plays a limiting role to separate adjacent materials. When the conveyor belt delivers the material to the discharge station, the groove of the discharge station is aligned with the feed end 15 of the unit guide groove, and the first push plate 2 moves to the right to push the material at the discharge station into the unit guide groove 5, and as the first push plate pushes, the material moves along the unit guide groove to the discharge end, and the first push plate moves to the left and resets. The material spacing at the discharge end corresponds to the position of the material picking part, and the material picking part 8 moves down to absorb the material at the discharge end, and then moves up to take out the material at the discharge end. The guide plate makes the spacing between adjacent materials at the discharge end consistent with the spacing of the material packaging. In this way, the material taken away by the material picking part does not need to adjust the spacing and can be directly used for packaging. The material picking part sends the taken out material to the packaging box of the feeding station.

[0031] Because the guide trough 5 gradually converges from the feed end 15 to the discharge end 16, if the guide trough is shorter, the angle change of the guide trough will be large, and the movement of materials in the guide trough will be easily obstructed. Increasing the length of the guide trough can alleviate the change from the feed end to the discharge end, which is more conducive to the movement of materials in the guide trough. If the guide trough is lengthened, the left and right movement stroke of the first push plate will be lengthened, affecting production efficiency. In order to increase the pushing efficiency, the pushing assembly also includes a second push plate 3, and the first push plate 2 and the second push plate are installed on the push plate seat 9. The push plate seat is connected to the power member three 10 that drives it to rise and fall. The power member three is installed on the second slide 12, and the second slide is connected to the power member four 11 that drives it to move left and right. When the first batch of materials is delivered to the discharge station by the conveyor belt 1, the power member 4 drives the first push plate 2 to move rightward, and the first push plate pushes the first batch of materials onto the guide plate. Then, the power member 3 10 drives the first push plate upward, and the power member 4 11 drives the first push plate to move leftward to the left side of the conveyor belt. The power member 3 drives the first push plate 2 downward to reset. At this time, the second batch of materials is delivered to the discharge station. The first push plate moves rightward again, pushing the second batch of materials on the conveyor belt into the guide chute. The second push plate 3 pushes the first batch of materials on the guide plate to the discharge end, which makes the movement more stable. During the pushing process, to prevent the materials from escaping the guide chute, a baffle 7 is provided at the discharge end of the guide chute. The baffle 7 can not only prevent the materials from escaping the guide plate, but also align the materials left and right at the discharge end, making full preparations for subsequent packaging.

[0032] The material picking member 8 is installed on the moving seat 6, and the right side of the material guide plate is the feeding station. The moving seat 6 is connected to the power member 14 that drives it to rise and fall. The power member 1 is installed on the first slide 13, and the first slide is connected to the power member 2 that drives it to move left and right; when picking up materials, the power member 2 drives the material picking member 8 to move to the material picking station, and then the power member 1 drives the material picking member 8 to move downward to absorb the material at the discharge end, and then the material picking member moves up, and the power member 2 drives the material picking member to move toward the feeding station. When the material picking member picks up materials, the power member 2 drives the material picking member to move downward to absorb the battery at the discharge end 16, and then the power member 2 drives the material picking member to move upward to make the battery out of the material guide trough, and then the power member 1 drives the material picking member to move to the right, and the battery moves to the top of the feeding station, and the material picking member moves downward again to place the battery in the packaging box or the transmission mold of the feeding station, and then the material picking member moves up and left to reset. The power member 1, the power member 2, the power member 3 and the power member 4 can be a cylinder, a screw mechanism and the like.

[0033] The feeding section of the conveyor belt is set on a support platform, which is mounted on a frame. A longitudinally arranged magnet is provided below the support platform. When the conveyor belt is feeding, the magnet has an adsorption effect, preventing the batteries from shaking during transportation and further improving the transportation stability.
