Description

Technical Field

[0001] This invention relates to the field of mobile phone manufacturing technology, and in particular to a material stripping device and loading / unloading equipment. Background Technology

[0002] Mobile phones are playing an increasingly important role in people's daily lives, and the requirements for them are also increasing. Mobile phones need to incorporate copper foil and speakers. The copper foil, placed on a substrate and bonded to a metal base, has excellent conductivity and provides electromagnetic shielding. The speaker generates mechanical vibrations that push the surrounding air, causing fluctuations in the air medium, thereby converting electrical energy into sound energy.

[0003] Currently, copper foil is not stored as individual sheets; multiple copper foils are arranged in a rectangular array on a sheet, which serves to support the multiple copper foils. While this structure facilitates packaging and transportation, the copper foils need to be peeled off the sheet before mounting. The sheet, specifically a release film, is relatively soft, making it difficult to tear the copper foil off. Manual peeling results in wrinkles in the copper foil, affecting the subsequent mounting quality, and the manual peeling process is inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a material stripping device and a loading and unloading equipment to improve production efficiency and assembly quality.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A material stripping device, comprising:

[0007] A stripping worktable is used to carry adhesive tape. The side of the adhesive tape away from the stripping worktable is an adhesive surface for adhering sheet material. Multiple second parts to be assembled are arranged on the sheet material. An inlet and an outlet are respectively provided at both ends of the stripping worktable.

[0008] A tape conveying mechanism is disposed below the stripping worktable. The tape conveying mechanism is configured to convey the tape and tension the tape around the inlet and the outlet respectively. The portions of the tape on both sides of the outlet are arranged at an angle so that the second part to be assembled is separated from the sheet at the outlet.

[0009] Preferably, a suction nozzle is provided on the stripping workbench. One end of the suction nozzle is connected to a vacuum generator, and the other end can be adsorbed onto the tape, so that the tape adheres to the surface of the stripping workbench.

[0010] Preferably, the assembly also includes a clamping member, which is rotatably mounted on the stripping worktable and is capable of abutting against the sheet and the second assembly to be assembled and pressing the sheet onto the tape.

[0011] Preferably, the tape conveying mechanism includes a feeding roller, a receiving roller, and a receiving drive source. The feeding roller is rotatably connected to the stripping worktable, and the receiving drive source can drive the receiving roller to rotate relative to the stripping worktable, so that the tape is tensioned and wound around the feeding roller and the receiving roller respectively.

[0012] Preferably, the tape conveying mechanism further includes a tape tensioning wheel, which is rotatably connected to the stripping worktable. The tape is wound around the tape tensioning wheel, and the tape tensioning wheel is used to tension the tape.

[0013] Preferably, the assembly also includes a feeding mechanism configured to carry a plurality of the stacked sheets and to convey them toward the stripping worktable.

[0014] Preferably, the material conveying mechanism includes:

[0015] A platform for supporting multiple sheets arranged in a stacked manner;

[0016] A lifting drive source, the output of which is connected to the platform, is capable of driving the platform and causing the sheet material to move vertically upward.

[0017] Preferably, the feeding mechanism further includes a fixed frame, with the lifting drive source disposed at the bottom of the fixed frame, and a limiting structure circumferentially disposed at the top of the fixed frame, the limiting structure being used to limit the sheet material.

[0018] Preferably, the device also includes a feeding mechanism configured to grip the sheet and transport it to the position where the tape is located at the inlet.

[0019] To achieve the above objectives, the present invention also provides a loading and unloading device, including the aforementioned stripping device.

[0020] The beneficial effects of this invention are:

[0021] The peeling device provided by this invention utilizes the adhesive surface of the tape to fix the sheet material, resulting in a simple structure and convenient use. A tape conveying mechanism transports the tape, winding it around the inlet and outlet. As the tape moves, it carries the sheet material adhered to it and the second assembly to be assembled, moving together. Due to the tape's support and transport, the sheet material is converted into a coil material, facilitating loading. Because the tape is taut, the portions on either side of the outlet are angled, while the portion on the peeling table is horizontal. The sheet material bends at the outlet, while the second assembly remains horizontal, separating the second assembly from the sheet material and achieving the peeling process for the second assembly. During this process, the arrangement of the stripping worktable and the conveyor belt mechanism allows for the stripping of multiple second parts to be assembled as the conveyor belt moves. This results in high stripping efficiency, eliminates the need for hand contact, avoids wrinkles on the second parts to be assembled, improves stripping quality, and ensures the assembly accuracy of the subsequent finished products.

[0022] The loading and unloading equipment provided by this invention saves time and effort, reduces the labor intensity of operators, saves production time, and thus improves production efficiency. Attached Figure Description

[0055] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0058] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0059] The loading and unloading equipment provided in this embodiment assembles a first component to be assembled and a second component to be assembled onto a carrier. This embodiment uses the assembly of a mobile phone as an example. The mobile phone includes a mid-frame, copper foil, and a speaker. A first receiving groove is provided within the mid-frame to accommodate the first component to be assembled, and a second receiving groove is used to accommodate the second component to be assembled. The speaker is placed in the first receiving groove of the mid-frame, and the copper foil is attached to the second receiving groove of the mid-frame. That is, the first component to be assembled is the speaker, the second component to be assembled is the copper foil, and the carrier is the mid-frame. Of course, the assembly equipment is not limited to assembling the mid-frame, speaker, and copper foil of a mobile phone; it can also assemble other electronic components.

[0060] like Figure 1 As shown, the loading and unloading equipment provided in this embodiment includes a support 5, a main body, and a housing. The main body is mounted on the support 5, which provides overall support. The housing covers the main body and the support 5 to prevent contamination of the main body and ensure the assembly accuracy of the main body. The width direction of the support 5 is defined as the X-axis, the length direction as the Y-axis, and the height direction as the Z-axis. The X, Y, and Z axes are mutually perpendicular. However, the X, Y, and Z axes only represent spatial directions and have no substantial meaning.

[0061] The main body of the loading and unloading equipment includes a feeding device 1, a stripping device 2, a conveying device 4, and an assembly device 3. The feeding device 1, conveying device 4, and stripping device 2 are arranged sequentially along the Y-direction. The feeding device 1 is used to convey the first part to be assembled, and the stripping device 2 is used to convey the second part to be assembled. The feeding device 1 and stripping device 2 are respectively located on both sides of the conveying device 4, facilitating the separate conveying of the first and second parts to be assembled to the conveying device 4 without interference in the conveying direction. The assembly device 3 can be located between the conveying device 4 and the feeding device 1, and between the conveying device 4 and the stripping device 2. The assembly device 3 is configured to grip the first part to be assembled on the feeding device 1 and the second part to be assembled on the stripping device 2, and attach the first and second parts to be assembled to the carriers located at the assembly station. The conveying device 4 has an inlet and an outlet at both ends. The conveying device 4 is configured to convey the carriers located at the inlet to the assembly station and convey the assembled finished workpieces to the outlet.

[0062] In the loading and unloading equipment provided in this embodiment, after the carrier is placed at the inlet, the conveying device 4 transports the carrier to the assembly station. At the same time, the assembly device 3 grabs the first part to be assembled on the feeding device 1 and the second part to be assembled on the stripping device 2, and attaches the first part to be assembled and the second part to be assembled to the carrier at the assembly station respectively. After the first part to be assembled, the second part to be assembled and the carrier are assembled, the conveying device 4 transports the assembled finished workpiece to the outlet.

[0063] By coordinating the feeding device 1, the stripping device 2, the conveying device 4, and the assembly device 3, time and labor are saved, the labor intensity of operators is reduced, and production time is saved, thereby improving production efficiency. At the same time, the skill requirements for operators are reduced throughout the assembly process, avoiding wrinkles and other issues caused by hands touching the first and second parts to be assembled, thus ensuring assembly quality and improving the assembly qualification rate.

[0064] The feeding device 1 can provide the first part to be assembled to the assembly device 3, and can continuously supply materials to the assembly device 3 to ensure the working efficiency of the loading and unloading equipment.

[0065] The specific structure of the feeding device 1 will be introduced first below.

[0066] like Figure 2 As shown, the feeding device 1 includes a feeding rack 11, a temporary storage mechanism 12, a lifting mechanism 13, and a conveying mechanism 14. The temporary storage mechanism 12 is slidably disposed on the feeding rack 11 to switch between inside and outside the feeding rack 11. When the temporary storage mechanism 12 is inside the feeding rack 11, it is in the feeding position; when the temporary storage mechanism 12 is outside the feeding rack 11, it is in the loading position.

[0067] The temporary storage mechanism 12 has a full-load section 122 for carrying a fully loaded tray 10 and an empty section 121 for carrying an empty tray 10. A lifting mechanism 13 is mounted on the feed rack 11. When the temporary storage mechanism 12 is in the loading position, the lifting mechanism 13 can lift the tray 10 placed on the full-load section 122 to a preset position. A conveying mechanism 14 is mounted on the upper end of the feed rack 11. When the temporary storage mechanism 12 is in the loading position, the conveying mechanism 14 is configured to convey the uppermost tray 10 on the lifting mechanism 13 to the empty section 121.

[0068] The working process of the feeding device 1 is as follows: the temporary storage mechanism 12 is pulled out from the feeding rack 11 to the feeding position. Multiple stacked, fully loaded trays 10 are manually placed into the full-load section 122, while the empty trays 10 in the empty section 121 are removed. Then, the trays 10 are pushed to the feeding position. The lifting mechanism 13 lifts the trays 10 placed on the full-load section 122 to a preset position, allowing the first assembly component in the uppermost tray 10 to be removed. After all the first assembly components in the uppermost tray 10 have been removed, the transport mechanism 14 transports the tray 10 to the empty section 121. The lifting mechanism 13 and the transport mechanism 14 repeat the above actions until all the material in all the trays 10 has been removed. The feeding device 1 provided in this embodiment does not require manual handling of individual trays 10, improving work efficiency and reducing workload.

[0069] like Figure 2 As shown, when multiple trays 10 are stacked in the full-load section 122 and the empty section 121, in order to prevent the trays 10 from tipping over, the temporary storage mechanism 12 also includes a door 124 and multiple baffles 125. The door 124 is connected to the end of the empty section 121 away from the full-load section 122 and is located on the outside of the feed rack 11. Multiple baffles 125 are spaced apart on the outer periphery of the empty section 121 and the full-load section 122. The baffles 125, the door 124 and the empty section 121 on the outer periphery of the empty section 121 form a first space for stacking empty trays 10, and the baffles 125 on the outer periphery of the full-load section 122 and the full-load section 122 form a second space for stacking full trays 10.

[0070] Specifically, the lifting mechanism 13 includes a first drive assembly connected to the feed rack 11 and a lifting plate 131 connected to the output end of the first drive assembly. The first drive assembly drives the lifting plate 131 to reciprocate in the vertical direction.

[0071] like Figure 2 and Figure 3As shown, specifically, the first drive assembly is a nut and screw mechanism driven by pulleys and a belt. The first drive assembly includes a first motor 132, two first driven pulleys 133, a first belt 134, and two screws 135. The cylinder of the first motor 132 is connected to the feeding frame 11. The drive pulley group is connected to the output shaft of the first motor 132. The first belt 134 is sleeved around the drive pulley group and the two first driven pulleys 133. The two screws 135 are spaced apart and rotatably mounted on the feeding frame 11. The first driven pulleys 133 are connected to the lower end of one screw 135. The lifting plate 131 is connected to the screw 135 via a nut. The output shaft of the first motor 132 rotates, driving the drive pulley group to rotate. The drive pulley group drives the belt to move, and the belt drives the two driven pulleys to rotate clockwise (counterclockwise). The two first driven pulleys 133 drive the screws 135 to rotate clockwise (counterclockwise), thereby causing the nut and the lifting plate 131 to rise. The output shaft of the first motor 132 rotates in the reverse direction, driving the drive wheel set to rotate in the reverse direction. The drive wheel set drives the belt to move, and the belt drives the two first driven wheels 133 to rotate counterclockwise (clockwise). The two first driven wheels 133 drive the screw 135 to rotate counterclockwise (clockwise), thereby causing the nut and the lifting plate 131 to descend.

[0072] like Figure 3 As shown, the drive wheel assembly includes a first tension wheel, a second tension wheel 137, and a third tension wheel 138 arranged in a triangle. The first tension wheel is connected to the output end of the first motor 132. The cylinder of the first motor 132 is mounted on the feed rack 11 and can slide in a direction perpendicular to the arrangement of the second tension wheel 137 and the third tension wheel 138. To enable the first motor 132 to slide, the cylinder of the first motor 132 is connected to a connecting plate 136. The connecting plate 136 has an elongated hole extending along the sliding direction of the first motor 132, and the bracket 5 has a threaded hole. After the first motor 132 slides into position, a bolt passes through the elongated hole and connects to the threaded hole. The bolt nut abuts against the connecting plate 136 to fix the first motor 132.

[0073] like Figure 2As shown, in order to enable the lifting plate 131 to lift the tray 10 located in the full-load section 122 and to avoid affecting the sliding of the temporary storage mechanism 12, the two lifting plates 131 are spaced apart. Both ends of the full-load section 122 are provided with clearance grooves 123, through which the lifting plate 131 can pass and abut against the lower surface of the lowest tray 10. After all the trays 10 on the lifting plate 131 have been transported to the empty section 121 by the conveying mechanism 14, the temporary storage mechanism 12 is pulled out. The first drive assembly drives the lifting plate 131 downwards to a position lower than the full-load section 122, thereby preventing the temporary storage mechanism 12 from being pushed to the loading position. When the temporary storage mechanism 12 is located in the feeding position inside the feeding rack 11, the first drive assembly drives the lifting plate 131 upwards until it abuts against the lower surface of the lowest tray 10. The first drive assembly then drives the lifting plate 131 to continue upwards until the uppermost tray 10 is located at a preset position.

[0074] In order for the conveying mechanism 14 to convey the material tray 10, the conveying mechanism 14 includes a second driving component, a connecting frame 141 and a first adsorption component 142. The second driving component is disposed at the upper end of the feeding rack 11, and is connected to the connecting frame 141 and drives the connecting frame 141 to move back and forth. The first adsorption component 142 is disposed on the connecting frame 141 and can adsorb the material tray 10.

[0075] Specifically, the second drive assembly is a pulley and belt drive structure, including a second motor 143, a second belt 146, a drive pulley 144, and a driven pulley 145. The second motor 143 is connected to the upper end of the feeding frame 11. The drive pulley 144 and the driven pulley 145 are spaced apart. The output shaft of the second motor 143 is connected to the drive pulley 144. The driven pulley 145 is rotatably mounted on the upper end of the feeding frame 11. The second belt 146 is sleeved around the drive pulley 144 and the driven pulley 145. The connecting frame 141 is connected to the second belt 146. The second motor 143 rotates clockwise and counterclockwise, driving the connecting frame 141 to reciprocate.

[0076] To avoid interference between the first adsorption component 142 of the conveying mechanism 14 and the tray 10, the conveying mechanism 14 also includes a first lifting drive component 147. The cylinder of the first lifting drive component 147 is connected to the connecting frame 141. The first adsorption component 142 is connected to the output end of the first lifting drive component 147. When it is necessary to adsorb the tray 10, the first drive component drives the connecting frame 141 to move directly above the tray 10. The first lifting drive component 147 drives the first adsorption component 142 to move downward to adsorb the tray 10. Then, the first lifting drive component 147 drives the first adsorption component 142 to move upward. The first drive component drives the connecting frame 141 to move directly above the empty section 121. The first adsorption component 142 cancels the adsorption of the tray 10. The tray 10 falls to the empty section 121 or onto the tray 10 located in the empty section 121 under the action of gravity.

[0077] If the material tray 10 falls onto the empty section 121 or onto the material tray 10 located in the empty section 121, it will cause the temporary storage mechanism 12 to vibrate. However, since the full material tray 10 has been lifted by the lifting plate 131, the full material tray 10 does not come into contact with the temporary storage mechanism 12. Therefore, the material in the full material tray 10 will not be affected by the vibration of the temporary storage mechanism 12.

[0078] To improve the compactness of the lifting mechanism 13, the cylinder of the first lifting drive 147 is connected to the upper side of the connecting frame 141, and its output end slides through the connecting frame 141 in the vertical direction. The first adsorption component 142 is located below the first lifting drive 147.

[0079] The stripping device 2 can provide the assembly device 3 with a second component to be assembled and can continuously supply material to the assembly device 3, ensuring the working efficiency of the loading and unloading equipment. Specifically, the second component to be assembled refers to copper foil. Existing copper foil is not existing as independent sheets; multiple copper foils are arranged in a rectangular array on a sheet material, which serves to support multiple copper foils. This structure facilitates transportation. When the copper foil needs to be mounted, it needs to be peeled off from the sheet material, which can also be called a release film. Because the sheet material is relatively soft, it is difficult to peel the copper foil off. Manual peeling would cause wrinkles in the copper foil, affecting the subsequent mounting quality, and manual peeling one by one results in low production efficiency.

[0080] To solve this problem, such as Figure 4As shown, the stripping device 2 provided in this embodiment includes a stripping worktable 21 and a tape conveying mechanism 22. The stripping worktable 21 has a cuboid shape and is used to carry the tape. The side of the tape away from the stripping worktable 21 is the adhesive surface, which is used to adhere the sheet material. Multiple second parts to be assembled are arranged on the sheet material. An inlet 211 and an outlet 212 are respectively provided at both ends of the stripping worktable 21. The tape conveying mechanism 22 is located below the stripping worktable 21. The tape conveying mechanism 22 is configured to convey the tape and tension the tape around the inlet 211 and the outlet 212 respectively. The portions of the tape on both sides of the outlet 212 are arranged at an angle, so that the second parts to be assembled are separated from the sheet material at the outlet 212. Optionally, the inlet 211 and the outlet 212 are the two short sides of the stripping worktable 21. Alternatively, a through hole can be provided at the end of the stripping worktable 21 away from the inlet 211, with the through hole located at the outlet 212. The tape enters the stripping worktable 21 from the inlet 211 and passes through the through hole.

[0081] The peeling device 2 provided in this embodiment utilizes the adhesive surface of the tape to fix the sheet material, resulting in a simple structure and convenient use. The tape is conveyed by the tape conveying mechanism 22 and wound around the inlet 211 and outlet 212 respectively. The tape conveying mechanism 22 conveys the tape, and as the tape moves, the sheet material and the second assembly to be assembled adhered to it move together. At this time, due to the carrying and conveying of the tape, the sheet material in a sheet state is converted into a roll material in a conveying state, facilitating material loading. Since the tape is in a taut state, the portions of the tape on both sides of the outlet 212 are set at an angle, while the portion of the tape on the peeling worktable 21 is horizontal. The sheet material bends at the outlet 212 following the tape, while the second assembly to be assembled remains horizontal, causing the second assembly to be assembled and the sheet material to separate, thus realizing the peeling process of the second assembly to be assembled. During this process, through the arrangement of the stripping worktable 21 and the conveyor belt 22, multiple second parts to be assembled can be stripped as the conveyor belt moves. The stripping efficiency is high, and there is no need for hand contact, which avoids wrinkles in the second parts to be assembled, improves the stripping quality, and thus ensures the assembly accuracy of the subsequent finished workpieces.

[0082] To ensure the flatness of the tape, suction nozzles are installed on the peeling worktable 21. One end of each nozzle is connected to a vacuum generator, and the other end can adhere to the tape, making the tape adhere to the surface of the peeling worktable 21. Optionally, multiple suction nozzles are arranged in a rectangular array on the surface of the peeling worktable 21, using vacuum adsorption to adsorb the tape, avoiding large gaps between the tape and the worktable surface that would cause unevenness, thus ensuring the flatness of the second part to be assembled. It is understood that the adsorption force of the suction nozzles is set within a certain range, ensuring both tape adsorption and flatness without creating excessive resistance to tape movement.

[0083] If the adhesion between the sheet material and the tape is not strong, peeling may occur at exit 212, affecting the peeling effect of the second part to be assembled. To solve this problem, such as Figure 4 As shown, the peeling device 2 also includes a clamping member 213, which is a cylindrical structure. The clamping member 213 is rotatably mounted on the peeling worktable 21. The clamping member 213 can abut against the sheet material and the second part to be assembled and press the sheet material onto the tape. By rotatably mounting the clamping member 213 on the peeling worktable 21, two purposes are achieved. First, as the tape moves, the clamping member 213, the sheet material, and the second part to be assembled roll together, making the bonding surface between the sheet material and the tape more stable. The sheet material will continue to move with the tape, thereby ensuring the peeling effect of the second part to be assembled from the sheet material. Second, the clamping member 213 acts like a rolling pin, smoothing out the second part to be assembled and the sheet material, further ensuring the flatness of the second part to be assembled.

[0084] Furthermore, the tape conveying mechanism 22 includes a feed roller 221, a take-up roller 222, and a take-up drive source 223. The feed roller 221 is rotatably connected to the stripping worktable 21, and the take-up drive source 223 can drive the take-up roller 222 to rotate relative to the stripping worktable 21, so that the tape is tensioned and wound onto the feed roller 221 and the take-up roller 222 respectively. Through the cooperation of the feed roller 221 and the take-up roller 222, the tape conveying is completed. It can be understood that the feed roller 221 only feeds the tape, while the take-up roller 222 winds up the tape with the attached sheet material.

[0085] Since the take-up roller 222 and the take-up drive source 223 are the active components for belt movement, to ensure the speed and accuracy of take-up, the number of take-up rollers 222 can optionally be two. Figure 5 As shown, a take-up drive wheel 224 is provided at the output end of the take-up drive source 223. A first annular groove and a second annular groove are provided at intervals on the outer wall of the take-up drive wheel 224. A first transmission belt 225 is tensioned and wound around the first annular groove and one of the take-up rollers 222, respectively. A second transmission belt 226 is tensioned and wound around the second annular groove and the other take-up roller 222, respectively. The take-up drive source 223 drives the take-up drive wheel 224 to rotate. As the first transmission belt 225 and the second transmission belt 226 move, they drive the two take-up rollers 222 to rotate. In this way, the synchronous rotation of the two take-up rollers 222 is ensured. The two take-up rollers 222 cooperate with each other to collect materials, which improves the speed and reliability of material collection.

[0086] Optionally, such as Figure 6As shown, a pressure roller 227 is provided above one of the take-up rollers 222. Both the take-up roller 222 and the pressure roller 227 are rotatably mounted on the take-up frame 228. The gap between the take-up roller 222 and the pressure roller 227 is very small, only able to accommodate tape and sheet material. The two sides of the tape abut against the take-up roller 222 and the pressure roller 227 respectively, so that the tape at the outlet 212 is in a taut state. Specifically, the tape conveying mechanism 22 also includes a spring 2281, a connecting bolt 2282, a damping element 2283, a rotating disk 2284, and a limiting element 2285, all connected to the take-up rack 228. The connecting bolt 2282 passes through the spring 2281. The upper end of the spring 2281 abuts against the inner wall of the take-up rack 228, and the lower end of the spring 2281 abuts against the damping element 2283. The damping element 2283 has a V-shaped groove on the side near the take-up roller 222. The rotating shaft of the take-up roller 222 is located in the V-shaped groove and abuts against the inner wall of the V-shaped groove, ensuring the rotation of the rotating shaft while limiting its movement to ensure structural stability. Utilizing the elasticity of the spring 2281, good compression can be ensured regardless of whether the material entering between the take-up roller 222 and the pressure roller 227 is pure tape or a combination of tape and sheet material. A limiting component 2285 is provided on the outside of the receiving rack 228. The limiting component 2285 is a strip structure, and the rotating shaft passes through the rotating disk 2284. A working surface is provided on the outer wall of the rotating disk 2284. The drive handle drives the rotating disk 2284 to rotate, so that the working surface abuts against the top surface of the limiting component 2285, which plays a limiting role.

[0087] Furthermore, such as Figure 5 As shown, the belt conveying mechanism 22 also includes a belt tensioning wheel 229, which is rotatably connected to the stripping worktable 21. The belt is wound around the belt tensioning wheel 229, which is used to tension the belt. Optionally, there are two belt tensioning wheels 229, which are respectively arranged on both sides of the stripping worktable 21.

[0088] Since the sheet materials carrying multiple second components to be assembled are stacked, in order to facilitate the loading of the sheet materials, such as Figure 7 As shown, the stripping device 2 also includes a conveying mechanism 23, which is configured to carry multiple stacked sheets and convey them toward the stripping worktable 21. By setting up the conveying mechanism 23, the sheet material is fed, which saves production time, reduces the labor intensity of operators, and has higher production efficiency compared with the manual feeding technology in the past.

[0089] Specifically, such as Figure 7As shown, the feeding mechanism 23 includes a fixed frame 231, a platform 232, and a lifting drive source 233. The fixed frame 231 is connected to the outside of the bracket 5 or the stripping worktable 21. The lifting drive source 233 is mounted on the fixed frame 231, which serves to mount the lifting drive source 233. The output end of the lifting drive source 233 is connected to the platform 232, which carries multiple stacked sheets. The lifting drive source 233 drives the platform 232 and causes the sheets to move vertically upward, i.e., the sheets move along the Z-axis. When the platform 232 is at its lowest point, multiple sheets are placed on it. Under the driving action of the lifting drive source 233, the platform 232 rises to its highest point, thus loading the sheets.

[0090] The lifting drive source 233 is specifically a lifting cylinder or a lifting motor. In this embodiment, the lifting drive source 233 is preferably a lifting motor. The output end of the lifting motor is connected to a lead screw, which is set along the Z-axis. A lead screw nut is sleeved on the lead screw and connected to the platform 232 through a mounting plate. The lifting motor drives the lead screw to rotate, and the lead screw nut moves along the axial direction of the lead screw while rotating with it, thereby driving the platform 232 and the sheet material to move along the Z-axis. This lifting motor is preferably a servo motor, which can control the step value of the servo motor. If the position sensor cannot detect the preset position, it means that the sheet material at the top layer has been loaded. At this time, the servo motor can step at least one sheet material thickness to avoid empty material.

[0091] During the sheet material feeding process, the platform 232 is positioned within the fixed frame 231 and can move relative to it along the Z-axis. The fixed frame 231 serves to accommodate and limit the platform 232. A lifting drive source 233 is provided at the bottom of the fixed frame 231, and a limiting structure 234 is provided around the top of the fixed frame 231 to limit the sheet material. Specifically, limiting strips extend inward from the top surface of the fixed frame 231, and multiple limiting strips are arranged around the perimeter of the fixed frame 231. When the platform 232 rises to its highest point, the limiting strips abut against the uppermost sheet material, preventing the lifting drive source 233 from raising the sheet material too high and affecting the feeding accuracy.

[0092] After the sheet material is fed, it needs to be moved to the inlet 211 of the stripping workbench 21. For this purpose, as follows... Figure 8 As shown, the stripping device 2 also includes a feeding mechanism 24, which is configured to grab the sheet material located on the conveying mechanism 23 and transport it to the position where the conveyor belt is located at the inlet 211. By setting up the feeding mechanism 24, the sheet material is transported, which saves production time, reduces the labor intensity of operators, and has higher production efficiency compared with the manual handling technology in the past.

[0093] The feeding mechanism 24 includes a driving component 241 and an adsorption component 242. The adsorption component 242 is used to adsorb the sheet material, and the driving component 241 is connected to the adsorption component 242 and can drive the adsorption component 242 to move along the X and Z directions respectively. Specifically, the driving component 241 includes a feeding X-direction driving source 2411, a feeding X-direction platform 2412, a feeding Z-direction driving source 2413, and a feeding Z-direction platform 2414. The feeding X-direction driving source 2411 is disposed on the support 5, and the output end of the feeding X-direction driving source 2411 is connected to the feeding X-direction platform 2412. The feeding X-direction driving source 2411 can drive the feeding X-direction platform 2412 to move along the X direction. A feeding Z-axis drive source 2413 is provided on the feeding X-axis platform 2412. The output end of the feeding Z-axis drive source 2413 is connected to the feeding Z-axis platform 2414, and the feeding Z-axis drive source 2413 can drive the feeding Z-axis platform 2414 to move along the Z-axis. An adsorption component 242 is provided on the feeding Z-axis platform 2414. Under the combined action of the feeding Z-axis drive source 2413 and the feeding Z-axis platform 2414, the adsorption component 242 can move along the Z-axis, which facilitates the adsorption component 242 to grasp and release the sheet material. Under the combined action of the feeding X-axis drive source 2411 and the feeding X-axis platform 2412, the adsorption component 242 can move along the X-axis, which facilitates the adsorption component 242 to transport the sheet material from the conveying mechanism 23 to the stripping worktable 21.

[0094] Specifically, the adsorption component 242 includes a suction cup 2421, which is mounted on the feeding Z-axis platform 2414. A vacuum generator is connected to the suction cup 2421. The vacuum generator creates a vacuum in the suction cup 2421, and the sheet material is adsorbed onto the suction cup 2421 using the negative vacuum pressure, resulting in good sheet material fixation. Simultaneously, the suction cup 2421 has a rectangular parallelepiped structure, and its adsorption surface is flat, preventing bending of the sheet material and ensuring its flatness.

[0095] The working process of the above-mentioned stripping device 2 is as follows:

[0096] After multiple sheets are stacked on the stage 232, the lifting drive source 233 can drive the stage 232 and move the sheets along the Z direction.

[0097] After the sheet material is fed, the drive component 241 of the feeding mechanism 24 drives the adsorption component 242 to move towards the carrier 232, so that the adsorption component 242 adsorbs the sheet material on the top layer. Then the drive component 241 drives the adsorption component 242 to move towards the stripping worktable 21, so as to place the sheet material at the position of the tape at the inlet 211, so as to convert the sheet material in the sheet state into the roll material in the conveying state.

[0098] The receiving drive source 223 drives the receiving roller 222 to rotate relative to the stripping table 21, so that the conveyor belt is tensioned and wound around the feeding roller 221 and the receiving roller 222 respectively, completing the conveyor belt conveying. As the conveyor belt moves, the sheet material and the second part to be assembled adhered to the conveyor belt move together. Since the conveyor belt is in a tensioned state, the part of the conveyor belt on both sides of the outlet 212 is set at an angle, and the part of the conveyor belt on the stripping table 21 is in a horizontal state. The sheet material follows the conveyor belt and bends at the outlet 212. At this time, the second part to be assembled is still in a horizontal state, so that the second part to be assembled and the sheet material are separated, realizing the stripping process of the second part to be assembled.

[0099] After the first and second components to be assembled are loaded, the assembly device 3 needs to assemble the first component to be assembled, the second component to be assembled, and the carrier component. For example... Figure 9 As shown, the assembly device 3 includes a first assembly component 31, a second assembly component 32, and a moving component 33. The first assembly component 31 is configured to selectively grasp a first component to be assembled, and the second assembly component 32 is configured to selectively grasp a second component to be assembled. The moving component 33 is connected to both the first assembly component 31 and the second assembly component 32, and can drive the first assembly component 31 and the second assembly component 32 to move towards the conveying device 4.

[0100] Specifically, the moving component 33 includes a moving X-axis drive source 331, a moving X-axis platform 332, a moving Y-axis drive source 333, and a moving Y-axis platform 334. The moving X-axis drive source 331 is mounted on the support 5, and its output is connected to the moving X-axis platform 332, enabling it to drive the moving X-axis platform 332 to move along the X-axis. Two moving Y-axis drive sources 333 are mounted on the moving X-axis platform 332, and their outputs are connected to the two moving Y-axis platforms 334, enabling them to drive the moving Y-axis platforms 334 to move along the Y-axis. A first assembly component 31 and a second assembly component 32 are respectively mounted on the two moving Y-axis platforms 334. By using a single moving component 33, both the first assembly component 31 and the second assembly component 32 can be simultaneously driven to move along both the X and Z axes.

[0101] Furthermore, such as Figure 10As shown, both the first assembly component 31 and the second assembly component 32 include a clamping component 321, a rotating component 322, and a lifting component 323. The clamping component 321 is used to clamp the first or second part to be assembled, ensuring the clamping stability of the part to be assembled. The lifting component 323 is connected to the movable Y-axis platform 334, and can drive the rotating component 322 to move up and down, i.e., move along the Z-axis. Through the cooperation of the movable component 33 and the lifting component 323, the clamping component 321 and the rotating component 322 can move along the X, Y, and Z axes respectively, allowing for flexible movement to ensure the accurate spatial assembly of the second part to be assembled. The rotating component 322 is connected to the clamping component 321, and can drive the clamping component 321 to rotate, used to adjust the angle of the clamping component 321 to ensure that the clamping component 321 clamps and attaches the second part to be assembled at the optimal angle.

[0102] Specifically, the lifting component 323 includes a lifting drive 3231 and a lifting platform 3232. The lifting drive 3231 is preferably a lifting cylinder. The output end of the lifting drive 3231 is connected to the lifting platform 3232, and the lifting drive 3231 can drive the lifting platform 3232 to move along the Z-axis. The rotating component 322 includes a rotary motor 3221 and a rotary platform 3222. The rotary motor 3221 is mounted on the lifting platform 3232, and its output end is connected to the rotary platform 3222. The rotary motor 3221 can drive the rotary platform 3222 to rotate. The clamping component 321 includes a main suction block 3211 and a secondary suction block 3212. A vacuum generator is connected to both the main suction block 3211 and the secondary suction block 3212. The main suction block 3211 primarily adsorbs the second part to be assembled, while the secondary suction block 3212 assists in adsorbing the second part to be assembled.

[0103] It is understandable that the selection of the main suction block 3211 and the auxiliary suction block 3212 in the clamping component 321 can be determined according to the size of the second component to be assembled. In this embodiment, the second component to be assembled is a copper foil, which requires a large adsorption area. Therefore, the clamping component 321 is equipped with both the main suction block 3211 and the auxiliary suction block 3212. If the clamping component 321 is used to adsorb the first component to be assembled, which is a speaker, the adsorption area required is small. Therefore, the clamping component 321 can be equipped with only the main suction block 3211.

[0104] To ensure the accuracy of assembly of assembly device 3, such as Figure 9As shown, the assembly device 3 also includes a first imaging component 34 and a second imaging component 35. The first imaging component 34 is disposed on the first assembly assembly 31 and is configured to detect the position of a first receiving groove in the carrier. The first receiving groove is used to receive a first part to be assembled. By detecting the position of the first receiving groove using the first imaging component 34, the position of the first part to be assembled can be adjusted according to the position information to ensure the placement accuracy of the first part to be assembled. The second imaging component 35 is disposed on the second assembly assembly 32 and is configured to detect the position of a second receiving groove in the carrier. The second receiving groove is used to receive a second part to be assembled. By detecting the position of the second receiving groove using the second imaging component 35, the position of the second part to be assembled can be adjusted according to the position information to ensure the placement accuracy of the second part to be assembled.

[0105] Furthermore, such as Figure 11 As shown, the conveying device 4 includes a barcode scanning mechanism 43, which is specifically a barcode scanner. The barcode scanning mechanism 43 is installed on the conveying device 4, preferably at the entrance of the conveying device 4. The barcode scanning mechanism 43 is used to identify the identification code of the carrier, thus playing the role of identifying the carrier.

[0106] Furthermore, the conveying device 4 also includes a conveying component 41 and a lifting component 42. The conveying component 41 can carry both ends of the carrier and convey them to the lifting component 42. The lifting component 42 can abut against the bottom of the carrier, causing the carrier to detach from the conveying component 41. The conveying component 41 can also carry both ends of the finished workpiece located on the lifting component 42 and convey them to the discharge port. The conveying component 41 realizes the conveying of the carrier and the finished workpiece, while the lifting component 42 serves as an assembly station, providing assembly space for the assembly of the carrier. Through the cooperation of the conveying component 41 and the lifting component 42, the conveying and assembly processes are uninterrupted, ensuring continuous production and high production efficiency.

[0107] Specifically, the conveying assembly 41 includes a conveying drive source 411, a conveying transmission assembly 412, and a conveyor belt 413. The conveying transmission assembly 412 includes a conveying drive wheel and a conveying driven wheel. The output end of the conveying drive source 411 is connected to the conveying drive wheel. The conveyor belt 413 is tensioned and wound around the conveying drive wheel and the conveying driven wheel. The conveying drive source 411 drives the rotation of the conveying drive wheel, which in turn drives the rotation of the conveying driven wheel and the movement of the conveyor belt 413. The conveyor belt 413 is used to carry the two ends of the carrier component or the two ends of the finished workpiece. The conveyor belt 413 can be an integral structure or a split structure. With an integral structure, one conveying drive source 411 can move the entire conveyor belt 413. The conveyor belt 413 is relatively long, but the number of drive sources is small, resulting in lower production costs. With a split structure, the conveyor belt 413 is divided into at least three sections: the first section is used for feeding the carrier component from the inlet; the second section is used to transport the carrier component to the assembly station; and the third section is used to discharge the finished workpiece from the outlet.

[0108] Understandably, if the conveyor belt 413 adopts a split structure, in order to ensure that each segment has a certain temporary storage space, a blocking component 46 is set between two adjacent segments. The blocking component 46 includes a blocking cylinder 461 and a blocking block 462. The blocking block 462 is set at the output end of the blocking cylinder 461. The blocking cylinder 461 drives the blocking block 462 to move upward along the Z direction to limit the carrier and prevent the carrier from flowing into the next segment temporarily. If the blocking cylinder 461 drives the blocking block 462 to move downward along the Z direction, it releases the carrier and allows the carrier to flow into the next segment temporarily. This is convenient, flexible, and meets different usage needs.

[0109] Furthermore, such as Figure 12 As shown, the lifting assembly 42 includes an assembly platform 421 and a lifting drive 422. The lifting drive 422 is specifically a lifting cylinder, and its output end is connected to the assembly platform 421. The lifting drive source 233 can drive the assembly platform 421 to move up and down. The assembly platform 421 is configured to carry the carrier component and the finished workpiece and to adsorb them. The assembly platform 421 provides a working space for assembling the carrier component. A suction nozzle is provided on the assembly platform 421 to adsorb the carrier component, preventing positional movement during assembly and ensuring assembly accuracy. By setting the lifting drive 422, the position of the assembly platform 421 relative to the conveyor belt 413 is adjustable. If the lifting drive 422 drives the assembly platform 421 to move upward along the Z-axis, the assembly platform 421 carries the carrier component and detaches it from the conveyor belt 413 to complete the assembly process. Subsequently, the lifting drive 422 drives the assembly table 421 to move downward along the Z direction, and the assembly table 421 carries the carrier component down to the conveyor belt 413, so that the carrier component is transported by the conveyor belt 413.

[0110] Furthermore, such as Figure 11As shown, the conveying device 4 also includes a first detection component 44 and a second detection component 45. The first detection component 44 and the second detection component 45 are respectively disposed on both sides of the conveying component 41. The first detection component 44 is used to detect the position of the first component to be assembled on the assembly device 3, and the second detection component 45 is used to detect the position of the second component to be assembled on the assembly device 3. By setting the first detection component 44 and the second detection component 45, precise positioning of the first component to be assembled, the second component to be assembled, and the carrier component is achieved. It can be understood that both the first detection component 44 and the second detection component 45 include a detection camera and a detection light source. The detection camera is used to photograph the first component to be assembled and the second component to be assembled, and the detection light source is used to provide sufficient light for the detection camera.

[0111] The production process of the loading and unloading equipment provided in this embodiment is as follows:

[0112] The carrier enters through the feed inlet of the conveying device 4. The barcode scanning mechanism 43 is used to identify the identification code of the carrier. The conveying assembly 41 can carry both ends of the carrier and convey it to the lifting assembly 42. The lifting assembly 42 can abut against the bottom of the carrier, so that the carrier is separated from the conveying assembly 41.

[0113] The feeding device 1 conveys the first part to be assembled, the first assembly component 31 grabs the first part to be assembled, and the moving component 33 can drive the first assembly component 31 to move toward the conveying device 4.

[0114] The stripping device 2 conveys the second part to be assembled, the second assembly component 32 grabs the second part to be assembled, and the moving component 33 can drive the second assembly component 32 to move toward the conveying device 4 respectively.

[0115] The first imaging component 34 detects the position of the first receiving slot, and the position of the first component to be assembled is adjusted according to the position information; the second imaging component 35 detects the position of the second receiving slot, and the position of the second component to be assembled is adjusted according to the position information. At the same time, the first detection component 44 is used to detect the position of the first component to be assembled on the assembly device 3, and the second detection component 45 is used to detect the position of the second component to be assembled on the assembly device 3, so that the first assembly component 31 and the second assembly component 32 complete the assembly of the first component to be assembled, the second component to be assembled, and the carrier.

[0116] The conveying device 4 transports the assembled finished workpiece to the discharge port.
