[0002] Carrier tape appearance inspection equipment is an automated device specifically designed for inspecting the appearance of carrier tapes. It includes a carrier tape marking mechanism, which punches holes in the marking material and affixes it to the carrier tape to achieve the marking purpose.

[0051] The core of the utility model is to disclose a carrier tape marking mechanism to achieve uniform punching of marking materials.

[0052] Another core of the present invention is to disclose a carrier tape appearance inspection device including the above-mentioned carrier tape marking mechanism.

[0053] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features of the embodiments of the present utility model may be combined with one another unless there is a conflict.

[0054] Combine Figure 1-Figure 5 The carrier marking mechanism disclosed in the present utility model includes a tape feeding assembly, a tape taking-up assembly, a marking assembly 400, an auxiliary assembly 500 and a control assembly; the tape feeding assembly includes a tape feeding wheel 200 for conveying the marking material 700, the tape feeding wheel 200 is used to install the marking material disk, the marking assembly 400 is provided with a punching position for punching the marking material 700, the tape taking-up assembly includes a tape taking-up wheel 300, the tape taking-up wheel 300 is used to wind and collect the remaining marking material 700 after being punched by the marking assembly 400; the auxiliary assembly 500 includes a rotating part 510 and a detection part 520, the detection part 520 is used to detect whether the rotating part 510 has rotated a preset angle.

[0055] Among them, the marking material 700 on the feeding wheel 200 is wound onto the take-up wheel 300 after passing through the punching position and the rotating part 510, and the rotating part 510 is driven by the marking material 700 to rotate synchronously. The control component is used to control the take-up wheel 300 to stop rotating when the detection part 520 detects that the rotating part 510 rotates a preset angle, and controls the marking component 400 to punch the marking material 700 at the punching position. After punching is completed, the control component controls the take-up wheel 300 to continue rotating.

[0056] In the present invention, since the rotating member 510 is driven to rotate synchronously with the marking material 700, when the rotating member 510 rotates by a preset angle, the marking material 700 moves a corresponding preset length. By controlling the take-up pulley 300 to stop after the rotating member 510 rotates by the preset angle, the marking material 700 stops moving after moving the preset length. At this time, the marking assembly 400 marks the marking material 700 at the punched positions, ensuring uniformity in the punched positions of the marking assembly 400.

[0057] Compared with the prior art, the present invention detects the rotation angle of the rotating member 510 through the detection member 520, and then controls the distance the marking material 700 moves between two punchings, which can achieve uniform punching of the marking material 700 and save marking material 700.

[0058] It should be noted that the marking assembly 400 includes a marking drive and a marking head, and its specific structure and operating mechanism are all prior art and will not be described in detail in this utility model. Along the moving direction of the marking material 700, the punching position can be set upstream or downstream of the rotating member 510.

[0059] Combine Figure 1 The carrier tape marking mechanism includes a mounting assembly 100, on which a tape feeding assembly, a tape receiving assembly, a marking assembly 400, an auxiliary assembly 500 and a control assembly can all be arranged.

[0060] Combine Figure 6-Figure 9 A detected portion 511 is provided on the rotating member 510. The detecting member 520 is configured to send a signal to the control component upon detecting the detected portion 511, thereby enabling the control component to determine whether the rotating member 510 has rotated by a predetermined angle. The number of detected portions 511 may be one or more. If there are multiple detected portions 511, the detected portions 511 may be arranged at intervals circumferentially around the rotation axis of the rotating member 510.

[0061] In one embodiment, combining Figure 6 、 Figure 7 and Figure 9, multiple detected parts 511 are arranged at equal intervals around the circumference of the rotation axis of the rotating member 510, and the central angle corresponding to two adjacent detected parts 511 is defined as α, then the preset angle is nα, where n is a positive integer, that is, when the detection member 520 detects the detected part 511 again after detecting the detected part 511 for the first time, it means that the rotating member 510 has rotated by angle α, and n can be adjusted according to α.

[0062] In another embodiment, combined Figure 8 There is one detected portion 511, positioned at any position along the edge of the rotating member 510. This means that the detected portion 511 is offset relative to the rotation axis of the rotating member 510. The control assembly determines the number of rotations of the rotating member 510 based on the number of times the detecting member 520 detects the detected portion 511. When the rotating member 510 rotates a preset number of revolutions (m), it indicates that the rotating member 510 has rotated a preset angle, which is (360m)°, where m is a positive integer.

[0063] Specifically, combined Figure 6 , the detected portion 511 may be a detection hole opened on the rotating member 510; or Figure 8 As shown, the detected portion 511 can be a detection protrusion provided on the rotating member 510. The detection member 520 includes, but is not limited to, a through-beam sensor. For example, when the detected portion 511 is a detection hole and the detection member 520 is a through-beam sensor, when the detection hole rotates to the through-beam sensor, the through-beam sensor is triggered once and sends a signal to the control component.

[0064] In one embodiment, the rotating member 510 includes a main body and an auxiliary part. Figure 1 and Figure 9 The main body cooperates with the marking material 700 and rotates synchronously. The auxiliary part is connected to the main body, and the detected part 511 is disposed on the auxiliary part. The auxiliary part and the main body can be separate structures or integrated structures. The main body is cylindrical and rotatably mounted on the mounting assembly 100. The outer surface of the main body, which is used to contact the marking material 700, is made of a material with a high roughness to prevent relative sliding between the two. The auxiliary part is plate-shaped and moves with the main body, and can cooperate with the detection member 520 to detect the rotation angle.

[0065] In a specific embodiment disclosed herein, the carrier tape marking mechanism further includes a guide assembly and an empty material sensor 110. The guide assembly includes a first guide wheel 600 and a second guide wheel 610. The first guide wheel 600 and the second guide wheel 610 are rotatably mounted on the mounting assembly 100 and are disposed on either side of the marking position, respectively, for guiding the marking material 700. The empty material sensor 110 is configured to detect whether the marking material 700 is present between the tape feed wheel 200 and the first guide wheel 600. Specifically, the empty material sensor 110 includes, but is not limited to, a through-beam sensor.

[0066] In addition, combined Figure 1 The rotating member 510 can also guide the marking material 700.

[0067] Combine Figure 10 and Figure 11 In order to ensure that the marking material 700 has a certain tension and facilitate the punching of the marking component 400, in some embodiments, the take-up component includes a take-up motor 310 that is transmission-connected to the take-up reel 300. The take-up motor 310 drives the take-up reel 300 to rotate actively, and the feed reel 200 follows the take-up reel 300 under the tension of the marking material 700, and a damping component is provided on the rotating shaft of the feed reel 200. The damping component is used to provide appropriate resistance to the rotation of the feed reel 200 to ensure the tension effect of the marking material 700. The specific structure and operation mechanism of the damping component are all existing technologies and will not be elaborated here.

[0068] In other embodiments, combined Figure 10 and Figure 11 The take-up assembly includes a take-up motor 310 that is transmission-connected to the take-up reel 300, and the take-up motor 310 drives the take-up reel 300 to actively rotate. The delivery assembly includes a delivery motor that is transmission-connected to the delivery reel 200, and the delivery motor drives the delivery reel 200 to actively rotate. The carrier tape marking mechanism also includes a tensioning assembly, which includes a tensioning wheel 130 and a swing arm 120. The swing arm 120 is rotatably mounted on the mounting assembly 100. The tensioning wheel 130 is rotatably mounted on the swing arm 120 and is used to tension the marking material 700 to reduce the impact of changes in the diameter of the marking material 700 on the delivery reel 200 and the take-up reel 300.

[0069] Further, combined with Figure 11The mounting assembly 100 is provided with a first chute and a second chute. A first stopper 140 and a second stopper 141 are respectively adjustable in position within the first chute and the second chute. The first stopper 140 and the second stopper 141 are used to limit the swinging of the swing arm 120 to two extreme positions. Specifically, when the swing arm 120 swings to the first extreme position, the swing arm 120 abuts against the first stopper 140. When the swing arm 120 swings to the second extreme position, the swing arm 120 abuts against the second stopper 141.

[0070] The first limiting member 140 and the second limiting member 141 may be bolts, and are tightened in the first sliding groove and the second sliding groove by nuts.

[0071] Combine Figure 11 A counterweight component 121 is provided on the swing arm 120. The counterweight component 121 and the tensioning wheel 130 are respectively arranged on both sides of the rotation fulcrum of the swing arm 120. The counterweight component 121 is used to balance the weight of the tensioning wheel 130 and adjust the tensioning force.

[0072] It is defined that when the swing arm 120 swings to the first extreme position, the extended length of the marking material 700 in the unwound state on the carrier tape marking mechanism is less than the extended length of the marking material 700 in the unwound state on the carrier tape marking mechanism when the swing arm 120 swings to the first extreme position. In one embodiment, the mounting assembly 100 is provided with a first sensor and a second sensor, and a detection object is provided on the swing arm 120. When the swing arm 120 swings to the first extreme position, the detection object triggers the first sensor, at which point the control assembly controls the tape feed motor to reduce the discharge speed of the tape feed roller 200. When the swing arm 120 swings to the second extreme position, the detection object triggers the second sensor, and the control assembly controls the tape feed motor to increase the discharge speed of the tape feed roller 200, thereby reducing the impact of changes in the diameter of the marking material 700 on the tape feed roller 200 and ensuring discharge stability.

[0073] It should be noted that, along the moving direction of the marking material 700, the tensioning assembly is preferably arranged near the tape feeding assembly, and the auxiliary assembly 500 is arranged near the tape taking-up assembly, so as to avoid the tensioning action of the tensioning assembly causing relative sliding between the marking material 700 and the rotating member 510.

[0074] Combine Figure 12 The carrier tape appearance inspection device disclosed in the present invention includes a carrier tape conveyor assembly 800 and the aforementioned carrier tape marking mechanism. The carrier tape conveyor assembly 800 is used to convey the carrier tape 710, and the carrier tape marking mechanism is used to mark the carrier tape 710. Due to the aforementioned carrier tape marking mechanism, the device also has the aforementioned structure and beneficial effects. Other structures refer to the prior art and are not described here in detail.

[0075] In a specific embodiment disclosed in the present utility model, the carrier marking mechanism includes two groups of carrier conveying components 800 and a carrier marking moving component 900. The carrier marking mechanism is arranged on the carrier marking moving component 900. The carrier marking moving component 900 is used to drive the carrier marking mechanism to move between the two groups of carrier conveying components 800 along a conveying direction perpendicular to the carrier conveying component 800 to improve marking efficiency and reduce equipment costs.

[0076] Specifically, the carrier marking moving assembly 900 includes a guide rail and a driving member. The guide rail extends between the two groups of carrier conveyor assemblies 800. The carrier marking mechanism slides along the guide rail through the driving member. The extension direction of the guide rail is perpendicular to the conveying direction of the carrier conveyor assembly 800, so that the carrier marking mechanism moves between the two groups of carrier conveyor assemblies 800 along the conveying direction perpendicular to the carrier conveyor assembly 800.

[0077] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Specific technical means in some embodiments may be incorporated in part or in whole into another embodiment, unless expressly excluded by another embodiment.
