[0029] Please refer to Figures 1 to 3 In one embodiment, the attaching device is used to attach tape to the surface of an electronic component. The attaching device includes an attaching head 100, a lifting mechanism 200, and a pressure detection mechanism 300. The attaching head 100 is used to attach tape. The lifting mechanism 200 is connected to the attaching head 100 and is used to drive the attaching head 100 to move along a first direction, which is the height direction of the attaching device. The pressure detection mechanism 300 is disposed on the lifting mechanism 200 and is used to detect the attaching pressure of the attaching head 100 in the first direction.

[0030] It should be noted that the first direction is Figures 1 to 3 The X direction is shown. Here, refer to... Figure 2 and Figure 3The tape is adsorbed onto the attachment head 100. The lifting mechanism 200 drives the attachment head 100 to move along the first direction to change the position of the tape on the attachment head 100 in the first direction. The tape is pushed along the direction closer to the electronic component by the attachment head 100 so that the tape can be smoothly adhered to the surface of the electronic component. At this time, the pressure detection mechanism 300 can detect the attachment pressure of the attachment head 100 in the first direction. When the attachment pressure is greater than the preset pressure, the pressure detection mechanism 300 will issue a warning signal to avoid excessive attachment pressure.

[0031] The aforementioned attaching device, driven by the lifting mechanism 200, moves the attaching head 100 along the first direction to change the position of the tape on the attaching head 100 in the first direction, so that the tape can be smoothly adhered to the surface of the electronic component. The pressure detection mechanism 300 can detect the attaching pressure of the attaching head 100 in the first direction, and can monitor the attaching pressure in real time, thereby improving the situation where electronic components are damaged due to excessive attaching pressure and improving the product stability of tape attachment.

[0032] In the embodiments of this application, the attachment head 100 is used to adsorb and fix the adhesive tape. The attachment head 100 is provided with adsorption holes and can be connected to an external negative pressure device to generate negative pressure in the adsorption holes to adsorb and fix the adhesive tape. The attachment head 100 is fixedly connected to the lifting mechanism 200. The attachment head 100 and the lifting mechanism 200 can be connected in various ways, as long as the attachment head 100 can move along the first direction with the lifting mechanism 200. The connection method between the attachment head 100 and the lifting mechanism 200 is not limited here.

[0033] In the embodiments of this application, the pressure detection mechanism 300 is used to detect the attachment pressure of the attachment head 100 in the first direction. The number of pressure detection mechanisms 300 is not limited to one. When the number of pressure detection mechanisms 300 is at least two, each pressure detection mechanism 300 is set in a different position to facilitate the accuracy of pressure detection.

[0034] For details, please refer to Figure 2 and Figure 3 The lifting mechanism 200 includes a lifting drive 210 and a lifting assembly 220. The lifting assembly 220 is fixedly connected to the lifting drive 210 and the attachment head 100 respectively. Under the drive of the lifting drive 210, the lifting assembly 220 moves along the first direction and drives the attachment head 100 to move along the first direction.

[0035] Understandably, driven by the lifting drive 210, the lifting assembly 220 moves along the first direction and drives the attachment head 100 to move along the first direction, so as to change the position of the tape on the attachment head 100 in the first direction.

[0036] In the embodiments of this application, the lifting drive component 210 is fixedly connected to the lifting assembly 220. The lifting drive component 210 and the lifting assembly 220 can be directly connected or indirectly connected through other components. Optionally, the lifting drive component 210 is a motor or other type of drive unit 211.

[0037] In the embodiments of this application, the lifting assembly 220 is fixedly connected to the attachment head 100. The lifting assembly 220 and the attachment head 100 can be directly connected or indirectly connected through other components.

[0038] Please refer to Figure 2 and Figure 3 The lifting assembly 220 includes a fixed base 221 and a lifting base 222. The lifting base 222 is slidably connected to the fixed base 221. The lifting drive 210 is installed on the fixed base 221 and connected to the lifting base 222. The attachment head 100 is installed on the lifting base 222. Under the drive of the lifting drive 210, the lifting base 222 slides relative to the fixed base 221 in a first direction, and drives the attachment head 100 to move in the first direction.

[0039] It should be noted that the lifting drive component 210 is mounted on the fixed base 221 and connected to the lifting base 222. This can be understood as follows: one part of the lifting drive component 210 is fixedly connected to the fixed base 221, and the other part is fixedly connected to the lifting base 222. Driven by the lifting drive component 210, the lifting base 222 slides along the first direction, causing the attachment head 100 to move along the first direction, while the fixed base 221 remains stationary.

[0040] In the embodiments of this application, the lifting seat 222 is slidably connected to the periphery of the fixed seat 221, and the lifting drive 210 is installed on the bottom side of the fixed seat 221 and connected to the lifting seat 222. The lifting seat 222 and the lifting drive 210 are connected to different sides of the fixed seat 221, which can make the structure of the lifting assembly 220 more compact and improve the space utilization of the fixed seat 221.

[0041] In the embodiments of this application, the attachment head 100 is installed on the lifting base 222, and the attachment head 100 and the lifting base 222 are detachably connected. For example, the attachment head 100 and the lifting base 222 are respectively provided with fixing holes, and fasteners such as screws are passed through the fixing holes of the attachment head 100 and the lifting base 222 to fix the two together.

[0042] In the embodiments of this application, a portion of the lifting drive 210 is fixedly connected to the fixed base 221, and another portion of the lifting drive 210 is fixedly connected to the lifting base 222; for example, the fixing portion of the lifting drive 210 is fixedly connected to the fixed base 221, and the output shaft of the lifting drive 210 is fixedly connected to the lifting base 222.

[0043] For details, please refer to Figure 2 and Figure 3 The lifting seat 222 includes a connecting plate 222a and two side plates 222b. The two side plates 222b are slidably connected to the fixed seat 221. The two side plates 222b are spaced apart along the second direction. The connecting plate 222a is located on the bottom side of the two side plates 222b. The attachment head 100 is fixed to the bottom side of the connecting plate 222a. The second direction intersects with the first direction but is not coplanar.

[0044] It should be noted that the second direction is Figure 2 and Figure 3 The Y direction is shown. Two side plates 222b are spaced apart along the second direction. The two side plates 222b are located on the top side of the connecting plate 222a, and the attachment head 100 is fixed to the bottom side of the connecting plate 222a. The two side plates 222b and the attachment head 100 are respectively located on different sides of the connecting plate 222a, which improves the space utilization of the connecting plate 222a and makes the overall structure of the lifting seat 222 more compact.

[0045] In the embodiments of this application, the two side plates 222b and the connecting plate 222a are separate structures, and the two side plates 222b and the connecting plate 222a can be detachably connected, for example, by screwing, plugging or other means to fix the side plates 222b and the connecting plate 222a; the two side plates 222b and the connecting plate 222a can also be an integral structure, for example, integrally formed by injection molding, casting or other means.

[0046] In the embodiments of this application, both side plates 222b and the connecting plate 222a are plate-shaped structures, and the outline of the plate-shaped structure can be rectangular, square, circular or other shapes.

[0047] In the embodiments of this application, the two side plates 222b are slidably connected to the fixed base 221, and the two side plates 222b can be respectively connected to the opposite sides of the fixed base 221; for example, the two side plates 222b and the fixed base 221 are slidably connected by a guide assembly (including a guide rail and a slider).

[0048] For more specific details, please refer to Figure 2 and Figure 3 The fixed base 221 includes a base 223 and a bracket 224. The bracket 224 is fixed to the bottom of the base 223, and two side plates 222b are respectively slidably disposed on both sides of the bracket 224 along the second direction.

[0049] It is understandable that the two side plates 222b are slidably connected to the bracket 224 of the fixed base 221. The bracket 224 is fixed to the bottom of the base. Under the drive of the lifting drive component 210, the lifting base 222 slides along the first direction and drives the attachment head 100 to move along the first direction. At this time, the base 223 and the bracket 224 are fixed.

[0050] In the embodiments of this application, the bracket 224 is fixedly connected to the bottom of the base 223, and the bracket 224 and the base 223 can be detachably connected, for example, fixed by screwing, plugging or other means; the bracket 224 and the base 223 can also be an integral structure, for example, integrally formed by injection molding, casting or other means.

[0051] In embodiments of this application, the side plate 222b is slidably connected to the bracket 224. For example, the side plate 222b and the bracket 224 are slidably connected by a guide assembly (including a guide rail and a slider).

[0052] Please refer to Figure 2 and Figure 3 The bracket 224 includes a mounting plate 224a and two support plates 224b, the two support plates 224b being spaced apart along a second direction, and the mounting plate 224a spanning between the two support plates 224b; the lifting assembly 220 also includes a lifting guide rail 225 and a lifting slider 226, the lifting slider 226 being slidably mounted on the lifting guide rail 225 along a first direction, the lifting guide rail 225 being fixed to the support plate 224b, and the lifting slider 226 being fixed to the side plate 222b.

[0053] It should be noted that the two support plates 224b are spaced apart along the second direction, and the mounting plate 224a spans the middle of the two support plates 224b. Under the drive of the lifting drive component 210, the lifting seat 222 slides along the first direction and drives the attachment head 100 to move along the first direction. At this time, through the setting of the lifting guide rail 225, the lifting slider 226 can slide along the lifting guide rail 225 to guide the sliding of the lifting seat 222 in the first direction.

[0054] In the embodiments of this application, the lifting guide rail 225 is fixed to the support plate 224b, and the lifting guide rail 225 and the support plate 224b can be detachably connected, for example, by screwing, plugging or other means.

[0055] In the embodiments of this application, the lifting slider 226 is fixed to the side plate 222b, and the lifting block and the side plate 222b can be detachably connected, for example, by screwing, plugging or other means.

[0056] For a specific embodiment, please refer to Figure 2 and Figure 3 The mounting plate 224a and the two support plates 224b are an integrated structure.

[0057] Understandably, the mounting plate 224a and the two support plates 224b are an integral structure, which enables the bracket 224 to have good overall integrity and high mechanical strength.

[0058] In the embodiments of this application, the mounting plate 224a and the two support plates 224b can be integrally formed by injection molding, casting or other methods.

[0059] Please refer to Figure 2 and Figure 3 The lifting drive component 210 includes a drive unit 211 and an extension rod 212. The drive unit 211 is fixed to the bottom side of the mounting plate 224a, one end of the extension rod 212 is connected to the drive unit 211, and the other end of the extension rod 212 is fixed to the top side of the connecting plate 222a.

[0060] Here, driven by the drive unit 211, the extension rod 212 extends and retracts in the first direction, causing the connecting plate 222a of the lifting seat 222 to move in the first direction, and causing the attachment head 100 to move in the first direction.

[0061] In the embodiments of this application, the drive unit 211 is fixedly connected to the bottom side of the mounting plate 224a. The drive unit 211 and the mounting plate 224a can be detachably connected, for example, fixed by screwing, plugging or other means. The drive unit 211 and the mounting plate 224a can also be an integral structure, for example, integrally formed by injection molding, casting or other means.

[0062] In the embodiments of this application, the other end of the extension rod 212 is fixedly connected to the top side of the connecting plate 222a. The extension rod 212 and the connecting plate 222a can be detachably connected, for example, by screwing or plugging. The extension rod 212 and the connecting plate 222a can also be an integral structure, for example, integrally formed by injection molding or casting.

[0063] Further, please refer to Figure 2 and Figure 3 The pressure detection mechanism 300 includes a pressure sensor 310, which is located at the other end of the extension rod 212 and is used to detect the attachment pressure of the attachment head 100 in the first direction.

[0064] It should be noted that, driven by the drive unit 211, the other end of the extension rod 212 extends and retracts in the first direction, causing the connecting plate 222a of the lifting seat 222 to move in the first direction, and causing the attachment head 100 to move in the first direction, so as to change the position of the tape on the attachment head 100 in the first direction, and push the tape in the direction closer to the electronic component through the attachment head 100 so that the tape can be smoothly adhered to the surface of the electronic component. At this time, the pressure detection mechanism 300 can detect the attachment pressure of the attachment head 100 in the first direction. When the attachment pressure is greater than the preset pressure, the pressure detection mechanism 300 will issue a warning signal to avoid excessive attachment pressure.

[0065] In the embodiments of this application, the pressure sensor 310 is disposed at the other end of the extension rod 212. The pressure sensor 310 can be a single-function sensor that can only detect pressure, or it can be a multi-function sensor that can detect pressure, temperature and humidity. The type of pressure sensor 310 is not limited here.

[0066] In the embodiments of this application, the number of pressure sensors 310 is not limited to one. When the number of pressure sensors 310 is at least two, each pressure sensor 310 can be set at a different position on the extension rod 212 to improve the accuracy of pressure detection.

[0067] Furthermore, please refer to Figure 2 and Figure 3 The pressure detection mechanism 300 also includes an adapter 320, which is fixed between the other end of the extension rod 212 and the connecting plate 222a, and the pressure sensor 310 is mounted on the adapter 320.

[0068] Here, the adapter 320 facilitates the installation and removal of the pressure sensor 310.

[0069] In the embodiments of this application, the adapter 320 is fixedly connected to the other end of the extension rod 212, and the adapter 320 and the extension rod 212 are detachably connected, for example, by screwing, plugging or other means.

[0070] In the embodiments of this application, the adapter 320 is fixedly connected to the connecting plate 222a. The adapter 320 and the connecting plate 222a can be detachably connected, for example, by screwing or plugging. The adapter 320 and the connecting plate 222a can also be an integral structure, for example, integrally formed by injection molding or casting.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
