Description

Technical Field

[0001] This application relates to automated equipment, and more particularly to an automatic tape applicator. Background Technology

[0002] When assembling components such as printed circuit boards (PCBs), one or more labels / tapes are usually affixed to their surfaces for identification in subsequent processes. Currently, most production lines use manual methods for this. To ensure accuracy, the PCBs are typically placed on a fixture and then inspected using a detection device. Based on the inspection results, they are placed in designated areas. For larger PCBs, the process can be done visually. However, this method involves actions such as fixing the PCB, picking up the label to be affixed, and removing it, resulting in low efficiency. Summary of the Invention

[0043] The automatic tape applicator 100 includes:

[0044] A control button 112 is provided on one side of the housing 110 to control the operation of the automatic tape applicator. In other embodiments, a human-machine interface may also be provided, which is external to or mounted on the housing 110. The human-machine interface is electrically connected to the control module inside the housing and controls the operation of the automatic tape applicator based on preset commands.

[0045] The housing 110 is provided with a feed port 111, which is used to transfer the attached finished product.

[0046] The housing 110 is equipped with

[0047] The base 120 has a supply unit 130 disposed on one side.

[0048] The supply unit 130 is equipped with a first supply module 140, a second supply module 150 and a third supply module 160 arranged in parallel.

[0049] The base 120 is equipped with a transmission module 120b and a transfer module 170 module located above the transmission module 120b. The transfer module 170 module is fixed to the base 120 by at least one fastener 171.

[0050] Transfer module 170 includes:

[0051] X-rail module 173, first Y-rail module 174, and second Y-rail module 175. The first Y-rail module 174 and the second Y-rail module 175 are configured in parallel and mounted on the same support 172.

[0052] The first Y-track module 175 is equipped with a tape supply unit 190.

[0053] The second Y-track module 174 has a suction section 180 located on the side away from the tape supply section 190. This suction section 180 is used to pick up stacked parts and place them on the transfer module 120b, which then transports them to a predetermined position (mounting position). The X-track module 173 extends into the supply section 130, meaning that the projection of the X-track module 173 onto the base surface 131 of the supply section 130 covers the first supply module 140, the second supply module 150, and the third supply module 160. This allows the suction section 180 to easily pick up the stacked parts and place them on the transfer module 120b.

[0054] In one embodiment, the transfer module 170 further includes an auxiliary X-rail module 173a. Through the cooperation between the auxiliary X-rail module 173a (which may include a linear guide rail but does not require linear drive components such as a linear motor) and the X-rail module 173, the device operates stably with minimal vibration.

[0055] The following is combined Figure 4-10 The internal structure of the automatic tape applicator according to the embodiments of this application will be described.

[0056] The transmission module 120b is configured on the base plate 120a, and the base plate 120a is mounted on the base 120.

[0057] The transmission module 120b includes: parallel transmission sections 121 / 121a, each equipped with a conveyor belt 122a, and rollers 122b (each roller is located at one end of the transmission section 121 / 121a) that match the conveyor belts 122a. The rolling of the rollers 122b drives the movement of the conveyor belts 122a, thereby moving the parts on the conveyor belts. The second Y-track module 174 is equipped with a code reading module and a matching light source 300.

[0058] The transmission section 121 has at least two connecting ends 1211 spaced apart, each fixed to the base plate 120a. Each connecting end 1211 has a first through hole 1212 with a thread matching the lead screw. The two connecting ends 121a2 spaced apart on the transmission section 121a are connected (or via a slider) to a guide rail 127. Each connecting end 121a2 has a second through hole 121a3 with a thread matching the lead screw. The lead screw 125 passes through the first through hole 1212 and the second through hole 121a3. In this embodiment, the transmission section 121a has two connecting ends 121a2 spaced apart. In other embodiments, there may be one or more connecting ends 121a2, which is not limited here. Rollers are mounted on one end of each of the two lead screws 125, and belts 125a are fitted onto the rollers. One lead screw 125 is connected to the output end of the drive motor 128 via the roller side. When adjusting the gap between the transmission section 121 and the transmission section 121a, the drive motor 128 drives the lead screw 125 connected to it to rotate, which in turn drives the belt 125a connected to the lead screw 125 to rotate, which in turn drives the other lead screw (not connected to the drive motor 128) to rotate, thereby moving the transmission section 121a (sliding along the track 127) to adjust the gap between the transmission sections 121 and the transmission section 121a.

[0059] The transfer module 120b includes: a fixing section (also called a placement station) located between parallel transfer sections 121 and 121a. The fixing section has an auxiliary plate 126, on which positioning pins 126a are provided away from the base plate 120a. These positioning pins 126a are used to fix the carrier 200 and the components stacked on it. A lifting cylinder 124 is located below the auxiliary plate 126, and its output end is connected to the auxiliary plate 126. A fixing member 122 is rotatably fixed to the outside of the transfer section 121 and / or the transfer section 121a via a pivot. During placement, the fixing member 122 rotates to... Figure 5 The component is positioned as shown to hold it in place. The lifting cylinder 124 actuates, raising its output end to push the auxiliary plate 126, along with the component, upwards. This is then combined with the fixing component 122 to secure the component before it enters the mounting process (e.g., applying high-temperature tape). A positioning camera module 123 and a matching light source 123a are mounted on the base plate 120a.

[0060] The suction unit 180 includes: a first bracket 181, one side of which is fixed to a first Y-track module 174; a first Z-axis drive unit 182 is disposed on the side of the bracket 181 away from the first Y-track module 174; the Z-axis drive unit 182 is connected to a second bracket 183; a rotating shaft 184 is disposed on the second bracket 183; the output end of the rotating shaft 184 is connected to a suction head 185; thus, the rotation of the rotating shaft 184 causes the suction head 185 to rotate, thereby performing the suction. In this embodiment, the suction head 185 includes a first suction mechanism 185b and a second suction mechanism 185a located on the first suction mechanism 185b. The first suction mechanism 185b is used to adsorb stacked carriers and substrates, and the second suction mechanism 185a is used to adsorb PCBs stacked on the substrates. Thus, the suction head 185 can adsorb three types of components (carriers, stacks and substrates on the carriers, and PCBs stacked on the substrates) at one time and transfer them to the mounting station for adhesive tape application. In one embodiment, the suction head is equipped with a suction cup spacing adjustment part, which can meet the suction requirements of PCBs of different sizes without having to replace the PCB suction head.

[0061] The tape supply unit 190 includes a second Z-axis drive unit 196, one side of which is connected to a second Y-rail module 175. The tape supply unit 190 is moved by the drive of the second Y-rail module 175. The tape supply unit 190 is also provided with a rotating part 192, through which the tape supply unit can be rotated by 90° (e.g., from its z-axis direction to the X / Y horizontal direction).

[0062] The tape supply unit includes a mounting plate 190a. One side of the mounting plate 190a has a receiving portion 193 for mounting the tape to be applied (e.g., high-temperature tape) 193a. After mounting, the tape 193a is connected to the tape application roller assembly 198 and the tape buffer component 197 via the roller assembly 198 and the tape buffer component 197. The tape application roller assembly 194 performs the application, cutting to a preset length, and rolling actions. In one embodiment, a detection component 195 is provided on the side of the tape application roller assembly 194. This detection component 195 detects whether the tape has been cut. If not cut, the tape is forcibly pressed down by the main shear point. At this time, there is a certain gap between the tape and the vacuum suction plate, which breaks the vacuum, allowing detection of the uncut tape, and then cutting. Preferably, the detection component 195 is a vacuum suction mechanism. The end of the detection component 195 is provided with a groove 195a, and a plurality of holes 195b are provided in the groove 195a, which are connected to a vacuum mechanism.

[0063] In one embodiment, a distance measuring module 199 is installed on the side of the mounting plate 190a away from the receiving portion 193. The distance measuring module 199 detects the length of the attached tape and cuts it when it reaches a preset length.

[0064] The supply unit 130 contains a first supply module 140, a second supply module 150, and a third supply module 160 arranged side by side. Each module is equipped with a side-push component (used to push out the components inside for easy access by the suction head 185). The first supply module 140 will be described below as an example. The first supply module 140 of the supply unit 130 has a Y-direction side-push component 141, an X-direction side-push component 142, and a lifting component 143 (for rapid replenishment after components from the previous layer are pushed out). In one embodiment, an ion blower is also provided on the side of the Y-direction side-push component 141 to remove static electricity from the components.

[0065] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
