Description

Technical Field

[0001] The present application relates to the field of automatic assembly of notebook computers, and in particular to an automatic feeding device for elastic pressure strips of notebook computers. Background Art

[0002] As a portable electronic product with powerful computing functions, laptop computers are widely used in work. In order to increase portability, current laptop computers are becoming thinner and lighter. In order to ensure stability, reduce vibration and provide heat dissipation space during use, elastic pads are usually provided on the bottom shell of the laptop computer. In the prior art, automated equipment is used to complete the loading and attachment process of the elastic pads. Generally, the incoming material of the elastic pads is in the form of attaching multiple elastic pressure strips on a plastic plate. The elastic pressure strips are removed from the plastic plate manually or mechanically, and then the single elastic pressure strip is transported to the attachment station for attachment. In the process of using automated equipment to load the elastic pressure strips, multiple plastic plates with elastic pressure strips are usually stacked up and down. However, due to problems with transportation or incoming materials themselves, the incoming materials may be placed in an inconsistent posture. Some plastic plates are placed at the bottom with the elastic pressure strips at the top, while others are placed at the bottom with the elastic pressure strips at the top of the plastic plates. As a result, when the equipment is used for automatic loading, it is impossible to load the materials in a uniform posture. When encountering incoming materials with abnormal postures, the machine needs to be stopped for manual adjustment, resulting in increased labor costs and affecting production efficiency.

[0039] The embodiment of the present application provides an automatic feeding device for an elastic pressure strip of a notebook computer.

[0040] like Figure 1 and Figure 2 As shown, the initial incoming material structure 1 of the elastic pressure strip 2 includes a carrier sheet 11 and a plurality of elastic pressure strips 2 that are spaced apart and arranged in parallel, the elastic pressure strip 2 includes a main body portion adhered to the carrier sheet 11 and a mounting post 21 located on the attachment surface of the main body portion, the carrier sheet 11 is provided with a socket for the mounting post 21 of the elastic pressure strip 2 to pass through, and a plurality of the elastic pressure strips 2 are located in the middle of the carrier sheet 11, the length of the carrier sheet 11 is greater than the length of the elastic pressure strip 2, that is, the edge area of ​​the carrier sheet 11 is not covered by the elastic pressure strip 2.

[0041] An automatic feeding device for elastic pressure strips of a notebook computer comprises:

[0042] like Figure 1 , Figure 2 and Figure 3As shown, the storage device 3 is used to store an initial incoming material structure 1 of a plurality of elastic pressure strips 2, and the plurality of initial incoming material structures 1 are distributed in the storage device 3 in sequence from top to bottom, and the correct state of the initial incoming material structure 1 in the storage device 3 is that the supporting sheet 11 is located below the main body of the elastic pressure strip 2; the storage device 3 includes a lifting component 37 and a distance sensor 38, and the lifting component 37 is used to lift the initial incoming material structure 1 in the storage device 3 upward until the supporting sheet 11 of the uppermost initial incoming material structure 1 reaches a preset height, the distance sensor 38 is electrically connected to the lifting component 37, and the distance sensor 38 is located above the storage device 3, and is used to detect the height of the supporting sheet 11 of the uppermost initial incoming material structure 1, and the distance sensor 38 sends a signal to the lifting component 37 to stop lifting when the supporting sheet 11 of the uppermost initial incoming material structure 1 reaches the preset height. In the embodiment of the present application, the two ends of the carrier sheet 11 are not covered by the elastic strips 2, and the distance sensor 38 is aligned with the portion of the carrier sheet 11 not covered by the elastic strips 2 to accurately determine the height of the carrier sheet 11. In the embodiment of the present application, the distance sensor 38 is an ultrasonic distance sensor.

[0043] like Figure 5 , Figure 6 and Figure 7 As shown, the separation device 4 is used to carry a single initial incoming material structure 1. When the initial incoming material structure 1 is on the separation device 4, the supporting sheet 11 is located below the main body of the elastic pressure strip 2. The separation device 4 is used to apply a downward force to the supporting sheet 11, and the separation device 4 is used to apply an upward force to the mounting column 21 to separate the elastic pressure strip 2 and the supporting sheet 11.

[0044] The first transport device is used to transport the initial incoming material structure 1 which is at the uppermost layer and in a correct state in the storage device 3 to the separation device 4 .

[0045] The second transport device is used to sequentially transport the elastic strips 2 separated from the carrier sheet 11 on the separation device 4 to the attachment station of the elastic strips 2 .

[0046] The cleaning device 5 is used to remove the carrier sheet 11 on the separating device 4 after all the elastic pressure strips 2 on the separating device 4 are transported to the attaching station.

[0047] When the uppermost initial incoming material structure 1 in the storage device 3 is transported to the separation device 4 by the first transport device, the distance sensor 38 detects that the height of the supporting sheet 11 of the uppermost initial incoming material structure 1 in the storage device 3 is lower than the preset height, and the lifting component 37 drives the initial incoming material structure 1 to rise, and the lifting component 37 stops rising when the supporting sheet 11 of the uppermost initial incoming material structure 1 reaches the preset height.

[0048] In the embodiment of the present application, when all the initial incoming material structures 1 in a storage device 3 are taken out, the machine can be manually stopped and reset, and the device can be restarted after the initial incoming material structures 1 are filled in the storage device 3.

[0049] Through the storage device 3, the first transport device, the separation device 4 and the second transport device, multiple elastic strips 2 adhered to the carrier sheet 11 can be separated from the carrier sheet 11, and the elastic strips 2 can be transported to the attachment positions in sequence. Finally, the cleaning device 5 is used to clean the carrier sheet 11 remaining on the separation device 4, so that the separation device 4 can perform a separation operation on the next initial incoming material structure 1.

[0050] In the embodiment of the present application, the first transport device includes a first three-coordinate mobile platform and a first adsorption component, the first adsorption component and the output end of the first three-coordinate mobile platform are connected to the first adsorption component, the first adsorption component is used to adsorb the upper surface of all elastic strips 2 on the uppermost initial incoming material structure 1, the stroke of the first three-coordinate mobile platform is determined by setting a program to ensure the precise displacement of the first adsorption component, the first three-coordinate mobile platform is used to drive the first adsorption component to move between the storage device 3 and the separation device 4, after the first adsorption component reaches the top of the separation device 4, the adsorption force is cancelled, and the initial incoming material structure 1 falls accurately on the separation device. The second transport device includes a second three-coordinate mobile platform and a second adsorption component, the second adsorption component and the output end of the second three-coordinate mobile platform are connected to the first adsorption component, the second adsorption component is used to adsorb the elastic strips 2 on the separation device 4, the second three-coordinate mobile platform is used to drive the second adsorption component to move between the attachment station of the separation device 4 and the elastic strips 2, the stroke of the second three-coordinate mobile platform is determined by setting a program to ensure the precise displacement of the second adsorption component, after the second adsorption component moves to the attachment station, the adsorption force is cancelled, and the elastic strips 2 fall on the corresponding position of the laptop computer. The first transport device and the second transport device are not shown in the figure.

[0051] like Figure 1 , Figure 3 and Figure 4As shown, the identification device 6 is used to identify whether the state of the initial incoming material structure 1 in the uppermost layer of the storage device 3 is correct. The identification device 6 includes a light emitting component 61, a light receiving component 62 and an identification controller. The light emitting component 61 includes a plurality of light emitters arranged at equal intervals. The light receiving component 62 includes a plurality of light receivers arranged at equal intervals. The light emitters and the light receivers correspond to each other one by one. The light emitters and the light receivers are respectively located on the opposite sides of the carrier sheet 11. The light receiver is used to receive the light signal emitted by the corresponding light emitter. The arrangement direction of the plurality of light emitters is arranged in the horizontal direction and the The light emitted by the light emitter is parallel to the top surface of the carrier sheet 11, and the light emitted by the light emitter is parallel or perpendicular to the length direction of the elastic strip 2. The distance between two adjacent light emitters is smaller than the distance between adjacent elastic strips 2 on the initial incoming material structure 1. The height of the light emitting component 61 and the light receiving component 62 is greater than a preset height, and the height difference between the light emitting component 61 and the preset height is smaller than the thickness of the elastic strip 2. The identification controller is used to receive an output signal of whether the light receiver receives the light signal emitted by the corresponding light emitting component 61, and the identification controller outputs the proportion of light receivers that receive the light signal to all light receivers.

[0052] like Figure 3 As shown, in this embodiment, the light emitted by the light emitter is parallel to the length direction of the elastic strip 2, that is, the light emitting component and the light receiving component are respectively located at the two ends of the elastic strip 2. When the state of the uppermost initial incoming structure 1 is correct, the main body of the elastic strip 2 located above the carrier sheet 11 blocks part of the light emitted by the light emitter, and the corresponding light receiver does not receive the light signal, and the light receiver between the adjacent elastic strips 2 receives the light signal; Figure 4As shown, when the topmost initial incoming material structure 1 is wrong, the amount of light blocked by the mounting column 21 above the supporting sheet 11 is less than the amount of light blocked by the main part of the elastic pressure strip 2 of the initial incoming material structure 1 in the correct state, and the number of light receiving components 62 that receive the light signal increases. In an embodiment of the present application, the number of light emitters is greater than the number of elastic strips 2 on the same initial material structure 1, the connection range of all light emitters covers all elastic strips 2 on an initial material structure 1, the spacing between two adjacent light emitters is less than half of the spacing between two adjacent elastic strips 2, and there is at least one light emitter between two adjacent elastic strips 2. Since the cross-section of the elastic strip 2 is arc-shaped, and the width of the elastic strip 2 corresponding to the light emitted by the light emitter is greater than the diameter of the mounting column 21, or the distance between the light emitted by the light emitter and the carrier sheet 11 at a preset height is less than half of the thickness of the elastic strip 2, that is, the light emitted by the light emitter corresponds to the part of the elastic strip 2 close to the carrier sheet 11, and the width of the side of the elastic strip 2 close to the carrier sheet 11 is larger, thereby ensuring that the number of lights emitted by the light emitter blocked by the elastic strip 2 is greater than the number of lights emitted by the emitter blocked by the mounting column 21.

[0053] The identification controller is electrically connected to the distance sensor 38. When the carrier sheet 11 of the uppermost initial incoming material structure 1 reaches a preset height, the distance sensor 38 sends a signal to the identification controller to start identification. The identification controller starts to judge whether the proportion of the number of optical receivers that currently receive the optical signal emitted by the optical transmitter to the total number of optical receivers is greater than a preset proportion. When the identification controller judges that the proportion of the number of optical receivers that receive the optical signal emitted by the optical transmitter to the total number of optical receivers is greater than the preset proportion, the identification controller outputs a status error of the uppermost initial incoming material structure 1.

[0054] In other embodiments, the light emitted by the light emitter is perpendicular to the length direction of the elastic strip 2, that is, the arrangement direction of the light emitter and the light receiver is parallel to the length direction of the elastic strip 2, the number of light emitters is greater than the number of mounting posts 21 on an elastic strip 2, there is at least one light emitter between the mounting posts 21 on the same elastic strip 2, and the connection lines of all light emitters cover at least half of the length range of the elastic strip 2, the light emitter is located on the outside of an outermost elastic strip 2 on one side of the carrier sheet 11, and the light receiver is located on the outside of an outermost elastic strip 2 on the other side of the carrier sheet 11, when the state of the uppermost initial incoming material structure 1 is correct, the light receivers within the entire length range of the elastic strip 2 cannot receive light signals, and when the state of the uppermost initial incoming material structure 1 is wrong, the mounting posts 21 block a small part of the light, and the number of light receivers receiving light signals increases.

[0055] The temporary storage device 7 is used to store a plurality of initial incoming material structures 1 in an erroneous state.

[0056] The third transport device is started when the identification controller outputs an error in the initial incoming material state, and the third transport device is transported to the temporary storage device 7 from the initial incoming material structure 1 in the uppermost layer of the storage device 3 in the error state. The third transport device includes a third three-coordinate mobile platform and a third adsorption component. The output ends of the third adsorption component and the third three-coordinate mobile platform are connected to the first three adsorption components. The third adsorption component is used to adsorb the carrier sheet 11 of the uppermost initial incoming material structure 1. The third three-coordinate mobile platform is used to drive the third adsorption component to move between the storage device 3 and the temporary storage device 7.

[0057] In addition to the control relationship already described, the coordination of the above-mentioned devices, the signal transmission and coordinated control between other devices can be realized by the central processing unit in combination with the corresponding sensors or corresponding actions. For example, the first transport device, the second transport device and the third transport device are controlled by the central processing unit. After all the elastic pressure strips 2 on the separation device 4 are transported away by the second transport device and the carrier sheet 11 is cleared, the central processing unit controls the first transport device to transport the initial incoming material structure 1 in the correct state from the storage device 3 to the separation device 4, and then the first transport device is reset. When the first transport device completes the transport action, the central processing unit receives the signal that the first transport device completes the transport, and the central processing unit starts the separation device 4 to separate the elastic pressure strips 2 and the carrier sheet 11, completing the separation. After separation, the central processor controls the second transport device to transport the elastic strips 2 in sequence from one side until all the transport is completed. An image sensor or a pressure sensor is set on the separation device 4 to detect whether there is an elastic strip 2 on the separation sensor. The action of the second transport device can also be used as a basis for judging whether there is still an elastic strip 2 on the separation device 4. For example, if there are four elastic strips 2 on a carrier sheet 11, the second transport device will transport four times in a row, indicating that there is no elastic strip 2 on the separation device 4. Then, the blank carrier sheet 11 is cleaned. After the carrier sheet 11 is cleaned, the central processor controls the first transport device to transport the initial incoming material structure 1 in the correct state from the storage device 3 to the separation device 4 again, and then reset, and then the cycle is repeated as above. Among them, the identification and removal of the initial incoming material structure 1 are carried out during the process of the second transport device transporting the elastic strip 2.

[0058] The present application identifies the state of the uppermost initial material structure 1 in the storage device 3 by setting an identification device 6, and removes the initial material structure 1 in an erroneous state through the third transport device, thereby preventing the initial material structure 1 in an erroneous state from being moved to the separation device 4 by the second transport device, ensuring that the separation device 4 can separate the carrier sheet 11 and the elastic pressure strip 2 of the initial material structure 1, stabilizing the reliable operation of the automatic feeding device and improving production efficiency. It also eliminates the need for a dedicated person to monitor the initial material structure 1 on the storage device 3 in real time, saving labor.

[0059] The light emitting component 61 and the light receiving component 62 are located outside the material storage device 3 , and a light-transmitting structure for light emitted by the light emitter to pass through is provided on the material storage device 3 .

[0060] like Figure 2 and Figure 3 As shown, the storage device 3 and the temporary storage device 7 both include an outer shell 31 and an inner sleeve 32, the inner sleeve 32 is placed in the outer shell 31, and a plurality of the initial incoming material structures 1 are stacked in sequence in the inner sleeve 32, the identification device 6 is located on the outer side of the outer shell 31 of the storage device 3, and the outer shell 31 and the inner sleeve 32 are provided with a light-transmitting structure for the light emitted by the light emitter to pass through, and the light-transmitting structure can be a hollow structure or the outer shell 31 and the inner sleeve 32 can be made of a transparent material.
