Detailed implementation manners

[0028] The invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the protection scope of the invention.

[0029] As Figures 1 to 6 shown, an automatic feeding device for a bulb painting machine includes a feeding mechanism 2. The feeding mechanism 2 includes a feeding chain 21, a plurality of fixing columns 22 correspondingly installed on the feeding chain 21, and a plurality of soft rubber heads 23 correspondingly installed on the tops of the plurality of fixing columns 22. Each soft rubber head 23 is provided with a groove 231 for inserting the lamp head of a bulb; preferably, the feeding chain 21 is arranged in a ring shape; preferably, the soft rubber head 23 is made of soft rubber, so that the soft rubber head 23 can be deformed, facilitating the insertion and fixation of the lamp head; the automatic feeding device of the bulb painting machine further includes a loading mechanism 3, a pressing mechanism 4, and a first clamping mechanism 5 and a second clamping mechanism 6 that cooperate with each other and are respectively located outside and inside the feeding chain 21; the first clamping mechanism 5 includes a first clamping chain 51 that rotates synchronously with the feeding chain 21, and a plurality of first clamping components correspondingly installed on the first clamping chain 51. Each first clamping component includes a first clamp 52; specifically, the first clamping chain 51 is also correspondingly arranged in a ring shape; the second clamping component includes a second clamping chain 61 that rotates synchronously with the feeding chain 21, and a plurality of second clamping components correspondingly installed on the second clamping chain 61. Each second clamping component includes a second clamp 62 that cooperates with the first clamp 52; specifically, the second clamping chain 61 is also correspondingly arranged in a ring shape; when the feeding chain 21, the first clamping chain 51, and the second clamping chain 61 rotate synchronously, adjacent first clamps 52 and second clamps 62 are used to correspondingly clamp a soft rubber head 23 and form a placement cavity 7 for positioning the bulb therebetween, as Figure 6 shown, that is, the placement cavity 7 is composed of a first placement cavity 71 on the first clamp 52 and a second placement cavity 72 on the second clamp 62, so that when the first clamp 52 and the second clamp 62 are combined, they can form a placement cavity 7 for positioning the bulb; and the loading mechanism 3 is used to send the bulb into the placement cavity 7; the pressing mechanism 4 is used to press the lamp head of the bulb in the placement cavity 7 into the groove 231. In use, through the combination of the first clamp 52 and the second clamp 62, a placement cavity 7 is formed therebetween. Then, the loading mechanism 3 sends the bulb into the placement cavity 7, and the pressing mechanism 4 presses the lamp head of the bulb into the groove 231, thus achieving the effect of automatic feeding and improving the production efficiency. It should be noted that the plurality of fixing columns 22 are arranged at equal intervals, and the plurality of first clamping components and the plurality of second clamping components are also arranged at equal intervals.

[0030] Among them, the first clamping component further includes a plurality of first driving teeth 53 correspondingly installed at the bottom of the first clamping chain 51. Specifically, the plurality of first driving teeth 53 are arranged at equal intervals; the second clamping component further includes a plurality of second driving teeth 63 correspondingly installed at the bottom of the second clamping chain 61. Specifically, the plurality of second driving teeth 63 are arranged at equal intervals; and a slot 221 is formed between adjacent fixing columns 22; the first driving teeth 53 and the second driving teeth 63 are used to correspondingly insert into the slot 221, so that when the feeding chain 21 rotates, the fixing column 22 pushes the first driving teeth 53 and the second driving teeth 63 to rotate synchronously, that is, drives the first feeding chain 51 and the second feeding chain 61 to rotate synchronously. As a preferred setting method in this embodiment, the feeding chain 21 is driven by a motor (not shown in the figure), which simplifies the structure and saves costs, and this structure that only uses one motor to make the feeding chain 21, the first clamping chain 51 and the second clamping chain 61 rotate synchronously ensures the action coherence among the feeding chain 21, the first clamping chain 51 and the second clamping chain 61, and prevents errors. However, those skilled in the art should know that if necessary, the first clamping chain 51 and the second clamping chain 61 can also be separately driven by a motor.

[0031] The first clamping component further includes a first connecting block 54, a first connecting rod 55 and a first spring (not shown in the figure); the first connecting block 54 is used to connect the first clamping chain 51, one end of the first connecting rod 55 is connected to the first connecting block 54, the first fixture 52 is slidably sleeved on the other end of the first connecting rod 55, the first spring is sleeved on the first connecting rod 55, and one end of the first spring is connected to the first connecting block 54, and the other end of the first spring is connected to the first fixture 52, so that the first fixture 52 has a certain elastic force; the second clamping component further includes a second connecting block 64, a second connecting rod 65 and a second spring (not shown in the figure); the second connecting block 64 is used to connect the second clamping chain 61, one end of the second connecting rod 65 is connected to the second connecting block 64, the second fixture 62 is slidably sleeved on the other end of the second connecting rod 65, the second spring is sleeved on the second connecting rod 65, and one end of the second spring is connected to the second connecting block 64, and the other end of the second spring is connected to the second fixture 62, so that the second fixture 62 has a certain elastic force. The specific setting method is that the first connecting block 54, the first feeding chain 51 and the first driving teeth 53 are connected by screws and nuts; and the second connecting block 64, the second feeding chain 61 and the second driving teeth 63 are connected by screws and nuts. Through the above settings, the first fixture 52 and the second fixture 62 can have a certain elastic force, so that when they clamp the bulb or the soft rubber head 23, they will not crush the bulb or the soft rubber head 23, ensuring the integrity of the equipment and the product, and also improving the yield rate of the product.

[0032] Such as Figure 2As shown in the figure, the loading mechanism 3 includes a vibrating disk 31 and a loading pipe rack 32; the feeding end of the loading pipe rack 32 is connected to the outlet of the vibrating disk 31, and the discharging end of the loading pipe rack 32 is aligned with a placement cavity 7. Preferably, the loading mechanism 3 further includes a guiding block 33; the guiding block 33 is fixed above the placement cavity 7, close to the discharging end of the loading pipe rack 32 and cooperating with the discharging end of the loading pipe rack 32. After the bulb is led out from the loading pipe rack 32, the guiding block 33 is used to guide the bulb into the placement cavity 7 to prevent the bulb from deviating from the preset route. For the convenience of guiding by the guiding block 33, an arc-shaped groove corresponding to the bulb can be provided on the side of the guiding block 33 facing the loading pipe rack 32, so that the bulb falls into the arc-shaped groove after being led out from the loading pipe rack 32 and is not easily separated from the arc-shaped groove, and then the bulb can accurately fall into the placement cavity 7. For the convenience of fixing the guiding block 33, the guiding block 33 is fixedly connected to a fixing seat.

[0033] The pressing mechanism 4 includes a first pressing wheel 41; the first pressing wheel 41 is rotatably fixed above the placement cavity 7 and is located behind the loading pipe rack 32. During the process of the feeding chain 51 driving the fixing column 22 to move, the bulb is introduced into the placement cavity 7 through the loading mechanism 3. Then, when the fixing column 22 continues to move, the bulb moves to the bottom of the first pressing wheel 41, and the bulb is pressed by the first pressing wheel 41 during the process of passing through the first pressing wheel 41, and the lamp head of the bulb is embedded into the groove 231.

[0034] To prevent the first pressing wheel 41 from pressing the bulb incompletely, the pressing mechanism 4 further includes a second pressing wheel 42; the second pressing wheel 42 is rotatably fixed above the placement cavity 7 and is located behind the first pressing wheel 41. By providing the second pressing wheel 42, the bulb will be further pressed by the second pressing wheel 42 after being pressed by the first pressing wheel 41, so as to ensure that the lamp head of the bulb can be accurately and stably embedded into the groove 231.

[0035] Of course, for the convenience of fixing the first pressing wheel 41 and the second pressing wheel 42, the first pressing wheel 41 and the second pressing wheel 42 are respectively fixedly connected to a fixing seat.

[0036] To enable the first pressing wheel 41 and the second pressing wheel 42 to press the bulb conveniently and accurately, a pressing groove 43 cooperating with the bulb is provided around the outer sides of the first pressing wheel 41 and the second pressing wheel 42, so that when the bulb passes through the first pressing wheel 41 and the second pressing wheel 42 respectively, the upper end of the bulb will be correspondingly embedded into the pressing groove 43, preventing the bulb from deviating from its position, and further enabling the first pressing wheel 41 and the second pressing wheel 42 to accurately and stably press the lamp head of the bulb into the groove 231.

[0037] When the feeding chain 21, the first clamping chain 51 and the second clamping chain 62 rotate synchronously, a clearance cavity communicating with the storage cavity 7 and corresponding to the soft rubber head 23 is formed between adjacent first clamps 52 and second clamps 62. The clearance cavity is used to embed the soft rubber head 23. As Figure 6 shown, the clearance cavity is composed of a first clearance cavity 81 on the first clamp 52 and a second clearance cavity 82 on the second clamp 62, so that when the first clamp 52 and the second clamp 62 are combined, a clearance cavity for fixing the soft rubber head 23 can be formed, and the first clamp 52 and the second clamp 62 can be accurately fitted. During use, the first clamp 52 and the second clamp 62 cooperate to fix the soft rubber head 23 by using the clearance cavity, and the upper end of the soft rubber head 23 penetrates into the storage cavity 7 to cooperate with the light bulb.

[0038] Of course, the present invention also has a frame 1 for installing the feeding mechanism 2, the loading mechanism 3, the pressing mechanism 4, the first clamping mechanism 5 and the second clamping mechanism 6.

[0039] The overall working principle of the present invention is introduced below for understanding the present invention:

[0040] First, when the device is started, the feeding chain 21 rotates to drive the first clamping chain 51 and the second clamping chain 61 to rotate synchronously. When the first clamping chain 51 and the second clamping chain 61 rotate, a first clamp 52 and a second clamp 62 sequentially and orderly clamp a soft rubber head 23, and a storage cavity 7 is formed between the first clamp 52 and the second clamp 62; the light bulbs sequentially pass through the vibrating disk 31 and the loading pipe rack 32, and fall into the storage cavity 7 through the guiding of the guiding block 33. At this time, the lamp heads of the light bulbs face downwards; then the light bulbs sequentially pass through the first pressing wheel 41 and the second pressing wheel 42 during the moving process and are sequentially pressed by the first pressing wheel 41 and the second pressing wheel 42, so that the lamp heads of the light bulbs are pressed into the grooves 231; finally, the light bulbs sequentially pass through the painting mechanism, the drying mechanism, the bubble collecting mechanism, etc. for painting and other operations during the moving process. In summary, through the above steps, the purpose of automatic bulb insertion can be achieved, the production efficiency is improved, the production cost is reduced, and the safety of the equipment is improved.

If various changes or deformations to the present invention do not depart from the spirit and scope of the present invention, and if these changes and deformations are within the scope of the claims of the present invention and equivalent technical scope, then the present invention also intends to include these changes and deformations.
