Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a jig for disassembling bottom covers. Background Technology

[0002] In modern industrial manufacturing processes, especially for products that have undergone processes such as spraying, electroplating, or assembly, specific fixtures are usually used to fix the main body of the product in order to carry out the corresponding processing operations. After a process is completed, the main body of the product needs to be removed from the fixture for subsequent packaging, inspection, or entry into the next production stage.

[0003] Currently, the operation of removing the main body of the product from the fixture still relies on manual labor on many production lines. This method is not only inefficient and labor-intensive, but also because it is difficult to maintain a constant force and angle during manual operation, the operator's fingernails or tools will directly contact the product surface during the product removal process. For products with high surface quality requirements, this will cause scratches, dents or contamination, thus affecting the product qualification rate.

[0004] To improve this situation, some simple mechanical structures are used to assist in product disassembly in some cases. However, these structures are often simply designed and lack precise guidance and limiting mechanisms. During the product ejection process, uneven force or positional deviation can also lead to product deformation or damage. Furthermore, these devices usually do not have the function of automatically transporting products to the next workstation. After the products are disassembled, they are scattered and piled up, still requiring manual secondary sorting and handling. This fails to achieve automated connection of the production process and restricts the improvement of overall production efficiency.

[0005] Therefore, this utility model proposes a product jig for disassembling the bottom cover to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of low product disassembly efficiency, easy damage to products and inconvenience of automation in the existing bottom cover disassembly jigs, this utility model aims to provide a bottom cover disassembly jig with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a product jig for disassembling the bottom cover, including an ejection mechanism and a positioning mechanism.

[0008] The ejection mechanism includes a pneumatic rod body, a pneumatic rod fixing plate, an ejector pin pressing plate, an ejector pin plate, an ejector pin body, and a clamping body. The positioning mechanism includes a conveyor belt, an electric push rod, and a moving plate.

[0009] The output end of the air rod body is fixedly connected to an air rod fixing plate. The bottom of the air rod fixing plate is integrally or fixedly connected to an ejector pin pressing plate. The bottom of the ejector pin pressing plate is fixedly connected to multiple sets of ejector pin bodies, and the ejector pin bodies slide through the clamping body.

[0010] Furthermore, the positioning mechanism is located below the ejection mechanism, the conveyor belt is used to carry the main body of the product, and the output end of the electric push rod is fixedly connected to a moving plate. The electric push rod drives the moving plate to move towards each other to push the main body of the product to the center position of the conveyor belt.

[0011] Preferably, the ejection mechanism further includes a guide rod and a spraying fixture positioning plate, the inner wall of the ejector pin pressing plate is slidably connected to the guide rod, and the bottom end of the guide rod is fixedly connected to the spraying fixture positioning plate.

[0012] Preferably, a pin guide plate is fixedly connected to the center of the top surface of the spraying fixture positioning plate, and the pin body slides through the pin guide plate.

[0013] Preferably, the ejection mechanism further includes a support plate and a pneumatic rod fixing block, wherein the pneumatic rod fixing block is fixedly connected to the outer wall of the pneumatic rod body, and the support plate is fixedly connected to the outer wall of the pneumatic rod fixing block.

[0014] Preferably, the ejection mechanism further includes a downward limiting plate, which is fixedly connected to the top of the spraying fixture positioning plate and limits the downward travel of the ejector plate.

[0015] Preferably, the positioning mechanism further includes a fixed base, an extension plate, and a limiting frame. The electric push rod is fixedly connected to the fixed base, and the extension plate is fixedly connected to the outer wall of the moving plate. The extension plate cooperates with the limiting frame to limit the moving distance of the moving plate.

[0016] Preferably, the bottom cover disassembly fixture also includes control buttons, and there are two sets of control buttons. Both sets of control buttons need to be activated simultaneously to make the gas spring body work.

[0017] Preferably, the inner wall of the clamp body has a clamping structure adapted to the shape of the product body for clamping the product body.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problems of low operating efficiency and product surface scratches or damage caused by uneven ejection force or positional deviation when manually or mechanically disassembling products in the prior art by setting up an ejection mechanism driven by the main body of the air rod to press down the ejector body, and using a guide rod, ejector guide plate and pressing limit plate. It achieves automatic, fast and accurate product ejection, while ensuring the stability and safety of the ejection process, and effectively improves production efficiency and product yield.

[0020] 2. This utility model solves the problem of inconsistent product positioning and low overall efficiency in automated production lines by setting a conveyor belt below the ejection mechanism and using electric push rods on both sides to drive the moving plates to move in opposite directions. This is achieved by setting a conveyor belt below the ejection mechanism and using electric push rods on both sides to drive the moving plates to move in opposite directions. The product's position is not fixed after it is disassembled and dropped, requiring manual secondary picking and positioning, which leads to poor connection between automated production lines and low overall efficiency. This achieves the effect of automatic conveying and precise centering of products, greatly facilitating the automated picking or processing of subsequent processes and improving the automation level and continuity of the entire production line.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 5 This utility model provides a product disassembly fixture for bottom cover, which aims to solve the problems of low product disassembly efficiency, easy damage to products, and inconvenience of automation in the prior art.

[0031] Please refer to Figure 1 and Figure 2 As shown, the bottom cover disassembly fixture includes an ejection mechanism 2 and a positioning mechanism 3 located below the ejection mechanism 2. The ejection mechanism 2 is used to eject and separate the product body 1 from the fixture body 214, serving as the core unloading unit of the entire fixture. The positioning mechanism 3 is used to receive, transport, and position the ejected product body 1, thereby achieving effective connection of the automated production line.

[0032] The ejection mechanism 2 consists of several closely fitted components, including a pneumatic rod body 204, a pneumatic rod fixing plate 205, an ejector pin pressing plate 207, an ejector pin plate 208, multiple sets of ejector pin bodies 209, and a clamping body 214. The output end of the pneumatic rod body 204 is fixedly connected to the pneumatic rod fixing plate 205, providing power for linear reciprocating motion. The bottom of the pneumatic rod fixing plate 205 is fixedly connected to the ejector pin pressing plate 207 to ensure effective power transmission. The bottom of the ejector pin pressing plate 207 is fixedly connected to multiple sets of ejector pin bodies 209, forming an overall downward pressing structure. The ejector pin bodies 209 slide through the pre-drilled holes inside the clamping body 214. When the ejector pin bodies 209 move downward, they can act on the product body 1 clamped in the clamping body 214, thereby ejecting it.

[0033] The ejection mechanism 2 also includes a guide rod 206, a spraying fixture positioning plate 211, an ejector pin guide plate 210, a support plate 201, a support reinforcing block 202, a pneumatic rod fixing block 203, a support block 212, and a downward pressure limiting plate 213. The outer wall of the pneumatic rod body 204 is bolted to the pneumatic rod fixing block 203. The outer wall of the pneumatic rod fixing block 203 is welded or bolted to the support plate 201. The outer wall of the support plate 201 is fixed to the support reinforcing block 202. These components together provide a stable installation and support structure for the pneumatic rod body 204. The bottom end of the guide rod 206 is bolted to the spraying fixture positioning plate 211, and the top of the spraying fixture positioning plate 211 is fixed to... A downward pressure limiting plate 213 is connected, which is located above the ejector plate 208. To provide downward pressure limiting, an ejector guide plate 210 is fixedly connected to the middle of the top surface of the spraying fixture positioning plate 211 by bolts. The ejector guide plate 210 provides precise guidance for the downward movement of the ejector body 209 and prevents the ejector body 209 from shifting. The inner wall of the spraying fixture positioning plate 211 is fixedly connected to the fixture body 214 by buckles or bolts. The inner wall of the fixture body 214 is used to clamp the product body 1. The bottom of the spraying fixture positioning plate 211 is fixedly connected to the support block 212 by bolts. The support block 212 serves as a connector to connect the ejector mechanism 2 to the positioning mechanism 3 at the bottom.

[0034] The positioning mechanism 3 includes a conveyor belt 302, an electric push rod 304, a moving plate 305, a fixed platform 301, a fixed seat 303, an extension plate 307, and a limiting frame 306. Multiple fixed platforms 301 are bolted to the bottom of the support block 212, providing basic support for the entire fixture. A conveyor belt 302 is rotatably connected to an adjacent side of the fixed platform 301. The conveyor belt 302 is located directly below the ejection mechanism 2 and is used to receive and transport the ejected product body 1. A fixed seat 303 is bolted to an adjacent side of the support block 212, providing support for the electric push rod 304. The mounting base is provided, and the output end of the electric push rod 304 is fixedly connected to the moving plate 305 by bolts. The electric push rod 304 drives the moving plate 305 to perform linear reciprocating motion. The outer wall of the moving plate 305 is fixedly connected to the extension plate 307 by bolts. When the moving plate 305 moves, the extension plate 307 moves synchronously. The extension plate 307 and the limit frame 306 make mechanical contact to form a limit structure, which is used to limit the moving distance of the moving plate 305. The bottom cover disassembly fixture also includes multiple control buttons 4. The control buttons 4 are connected to the control circuit of the air rod body 204 through wires to control the start and stop of the air rod body 204.

[0035] Please refer to Figure 2 and Figure 3The ejection mechanism 2 includes multiple guide rods 206 arranged in a vertical direction. The bottom end of the guide rod 206 is fixedly connected to the spraying fixture positioning plate 211 by bolts. The upper end of the guide rod 206 is a free end. The guide rod 206 provides precise vertical guidance for the movement of the ejector pin pressing plate 207.

[0036] The ejector pin pressing plate 207 is provided with a guide hole that matches the guide rod 206. In the assembled state, the guide hole of the ejector pin pressing plate 207 slides against the outer peripheral wall of the guide rod 206, ensuring that the ejector pin pressing plate 207 can remain stable when it reciprocates under the drive of the air rod body 204, effectively avoiding shaking or tilting during the movement, thereby ensuring that the ejector pin body 209 acts vertically on the product body 1.

[0037] The ejection mechanism 2 also includes an ejector guide plate 210, which is fixedly connected to the top center of the spraying fixture positioning plate 211 by bolts. The ejector guide plate 210 has multiple guide holes, the number and position of which correspond one-to-one with the ejector body 209. The needle body of the ejector body 209 slides through the guide holes of the ejector guide plate 210. This structure provides secondary guidance and support for the multiple slender ejector bodies 209 during the pressing process, further enhancing the accuracy of the ejection action and preventing the ejector body 209 from bending or deviating from the predetermined ejection point due to force.

[0038] The ejection mechanism 2 also includes a downward limiting plate 213, which is fixedly connected to the top of the spraying fixture positioning plate 211 by bolts. As a mechanical limiting block, when the ejector plate 207 drives the ejector plate 208 to the predetermined position, the lower surface of the ejector plate 208 will contact the upper surface of the downward limiting plate 213, thereby preventing the ejector plate 208 from continuing to descend. This mechanical limiting structure accurately controls the ejection stroke of the ejector body 209 and effectively prevents damage to the product body 1 or the fixture body 214 caused by excessive ejection force or excessive stroke.

[0039] Please refer to Figure 4 and Figure 5 The positioning mechanism 3 includes a limiting frame 306 and an extension plate 307. The outer wall of the fixed base 303 is integrally formed or welded with multiple sets of limiting frames 306. The limiting frame 306 has a U-shaped or C-shaped structure. The outer wall of the movable plate 305 is fixedly connected to the extension plate 307 by bolts. The shape of the extension plate 307 is adapted to the inner contour of the limiting frame 306.

[0040] In the assembled state, the extension plate 307 extends into the interior of the limiting frame 306. When the electric push rod 304 drives the moving plate 305 to move towards the center, the extension plate 307 moves accordingly until the outer side wall of the extension plate 307 contacts the inner side wall of the limiting frame 306, thereby limiting the maximum distance the moving plate 305 can move. This ensures that the moving plate 305 can stop at the same precise position each time it is positioned, providing a stable and reliable positioning reference for subsequent processes.

[0041] As a preferred embodiment, in order to improve operational safety, the bottom cover disassembly fixture also includes control buttons 4. There are two sets of control buttons 4. The control buttons 4 are connected to the control circuit of the air rod body 204 through wires, so that the air rod body 204 can only work when both sets of control buttons 4 are activated at the same time. When either control button 4 is released, the air rod body 204 stops working.

[0042] As another preferred embodiment, in order to enhance the stability of the gas rod body 204 installation, the support plate 201 and the support reinforcement block 202 are connected by bolts or welding. The support reinforcement block 202 provides additional structural strength to the support plate 201, effectively resisting the reaction force generated when the gas rod body 204 is working.

[0043] As another preferred embodiment, in order to ensure that the ejector body 209 is accurate and does not deviate during the downward movement, the ejector guide plate 210 is provided with guide holes corresponding to the number and shape of the ejector bodies 209. When the ejector body 209 moves downward, it passes through the guide holes of the ejector guide plate 210. The ejector guide plate 210 provides guidance for the ejector body 209 and prevents the ejector body 209 from shaking or deviating during the movement.

[0044] In another preferred embodiment, in order to accurately control the ejection stroke and prevent damage to the product body 1 or the fixture body 214 due to excessive pressure, the pressure limiting plate 213 is fixedly connected to the top of the spraying fixture positioning plate 211, and the bottom of the pressure limiting plate 213 contacts the top of the ejector plate 208, providing a physical limit for the downward movement of the ejector plate 208.

[0045] In another preferred embodiment, in order to achieve automatic connection of the product body 1 from the ejection station to the next processing stage, the conveyor belt 302 is rotatably connected to the adjacent side of the fixed platform 301. The conveyor belt 302 is preferably a polyurethane belt, and the surface of the conveyor belt 302 has anti-slip texture to ensure that the product body 1 can be transported stably after falling onto the conveyor belt 302 and to avoid slipping.

[0046] In another preferred embodiment, in order to achieve precise centering of the product body 1, the output end of the electric push rod 304 is fixedly connected to the moving plate 305 by bolts. The electric push rods 304 are all fixedly connected to the adjacent side of the fixed seat 303 by bolts. The fixed seat 303 is fixedly connected to the adjacent side of the support block 212 by bolts. After the two sets of electric push rods 304 are started, the moving plate 305 moves synchronously towards the center, pushing the product body 1 on the conveyor belt 302 to the middle position, which is convenient for subsequent gripping or processing.

[0047] In another preferred embodiment, in order to precisely control the positioning stroke of the moving plate 305, an extension plate 307 is fixedly connected to the outer wall of the moving plate 305 by bolts, and multiple sets of guide rods 206 are fixedly connected to the outer wall of the fixed seat 303 by bolts. When the moving plate 305 drives the extension plate 307 to move synchronously, the extension plate 307 will touch the fixedly installed limit frame 306. The limit frame 306 and the side surface of the extension plate 307 are in contact with each other, thereby limiting the farthest moving distance of the moving plate 305 and ensuring the accuracy and consistency of each positioning.

[0048] Working principle: When the device needs to push out the main body 1 of the product, the operator needs to activate two sets of control buttons 4 at the same time to ensure the safety of operation. After the control buttons 4 are activated, the main body 204 of the air rod starts to work under the command of the control system. The output end of the main body 204 of the air rod drives the air rod fixing plate 205 to move downward. Since the outer wall of the main body 204 of the air rod is fixedly connected to the air rod fixing block 203, the outer wall of the air rod fixing block 203 is fixedly connected to the support plate 201, and the outer wall of the support plate 201 is fixedly connected to the support reinforcement block 202, a stable installation and support are provided for the main body 204 of the air rod, ensuring the stability of the movement of the main body 204 of the air rod.

[0049] The bottom of the pneumatic rod fixing plate 205 is provided with a ejector pin pressing plate 207. The inner wall of the ejector pin pressing plate 207 is slidably connected to the smooth cylindrical outer surface of the guide rod 206. The bottom end of the guide rod 206 is fixedly connected to the top of the spraying fixture positioning plate 211. Therefore, the output of the pneumatic rod body 204 drives the ejector pin pressing plate 207 to slide downward along the outer wall of the guide rod 206. This sliding fit structure between the guide rod 206 and the guide hole ensures that the ejector pin pressing plate 207 maintains a stable vertical posture during the descent, effectively resists lateral forces, and prevents the ejector plate 208 and the ejector body 209 from tilting or getting stuck during the pressing process, providing a precise positioning effect for the subsequent ejection action.

[0050] The bottom of the ejector plate 207 is fixedly connected to the ejector plate 208, and the bottom of the ejector plate 208 is fixedly connected to multiple sets of ejector bodies 209. Therefore, the downward movement of the ejector plate 207 will drive the ejector plate 208 and the ejector body 209 to move downward synchronously. The top surface of the spraying fixture positioning plate 211 is fixedly connected to the ejector guide plate 210. The ejector body 209 moves downward and passes through the guide hole of the ejector guide plate 210. The ejector guide plate 210 provides precise guidance for the ejector body 209, thereby effectively preventing the ejector body 209 from shifting during the downward pressing process and ensuring that the ejector body 209 accurately acts on the product body 1.

[0051] A downward limiting plate 213 is fixedly connected to the top of the spraying fixture positioning plate 211. When the downward limiting plate 213 contacts the ejector plate 208, it provides a downward limiting for the ejector plate 208, preventing the ejector plate 208 from moving too far downward, thereby effectively avoiding damage to the product body 1 caused by excessive movement. A fixture body 214 is fixedly connected to the inner wall of the spraying fixture positioning plate 211. The inner wall of the fixture body 214 holds the product body 1. When the ejector body 209 moves down and contacts the product body 1, the product body 1 is subjected to an ejection force and is released from the clamping of the fixture body 214, thereby completing the ejection action. Through the overall coordinated action of the ejection mechanism 2, this utility model realizes the automated, safe and accurate ejection of the product body 1 from the fixture body 214, effectively avoiding scratches on the product body 1 due to overlap, and improving production efficiency and product quality.

[0052] After the main body 1 is ejected, it falls freely onto the conveyor belt 302 supported by the fixed platform 301. The rotation of the conveyor belt 302 transports the main body 1 to the next processing stage, realizing automated material conveying. In order to accurately position the main body 1 for subsequent processing, the operator will activate two sets of electric push rods 304. The output end of the electric push rod 304 is fixedly connected to a moving plate 305. An extension plate 307 is fixedly connected to the outer wall of the moving plate 305. The fixed base 303 is fixedly connected to the electric push rods 304. The fixed base 303 is fixedly connected to the overall frame of the fixture through the support block 212. When the two sets of electric push rods 304 are activated, they will synchronously convey... The movable plate 305 moves towards the center, thereby pushing the product body 1 on the conveyor belt 302 to the preset position in the middle. During the movement, the extension plate 307 moves synchronously until the extension plate 307 touches the fixedly set limit frame 306. The limit frame 306 and the side surface of the extension plate 307 come into contact with each other, providing a mechanical limit on the movable plate 305, thereby accurately limiting the maximum moving distance of the movable plate 305 and ensuring the accuracy and consistency of each positioning. Through the above-mentioned functions of the positioning mechanism 3, this utility model realizes the precise positioning of the product body 1, which greatly facilitates the subsequent automated processing and improves the intelligence level of the entire production line.
