Description

Technical Field

[0001] This utility model relates to the field of production and processing, and in particular to a stable locking baking clamp and a baking feeding device. Background Technology

[0002] Some high-precision electronic components, such as high-precision circuit boards or semiconductor wafers, require repeated baking to remove internal moisture and impurities, ensuring stable product quality. However, because both baking surfaces of the product need to be protected throughout the process and cannot be exposed to foreign objects, and because the middle section of both sides is a precision part, contactless feeding is required during the baking process to protect the material. Furthermore, both sides of the material must be baked without contact.

[0003] Conventional baking methods are unsuitable for this type of product. Because baking involves laying the material flat, critical parts may come into contact with the tray, leading to damage. Furthermore, the material may deform under gravity after baking. Accidental contact during handling can easily damage delicate components.

[0004] Currently, no suitable technical solution has been found for this type of product, so a new technical solution is needed to solve the problem of material baking and feeding. Utility Model Content

[0005] The purpose of this invention is to solve one of the above-mentioned defects and provide a stable and engaging baking fixture and baking feeding device.

[0006] The objective of this utility model is achieved through the following means:

[0007] A stable, locking baking fixture includes a material tray and a locking buckle disposed on the edge of the material tray. The material tray has a frame-like structure, through which the front and back sides of the material to be baked are exposed. The locking buckle includes a pressing block, a force-bearing part, and a reset structure. Under the action of an external force, the force-bearing part drives the locking buckle to perform an opening action. When the external force disappears, the reset structure is used to drive the locking buckle to a pressed state, and maintains a continuous pressed action after pressing. The pressing block is used to press the material against the edge of the material tray and fix the material on the material tray, so that the material can move with the movement of the material tray.

[0008] As a preferred embodiment, the force-bearing part is a pull rod, which causes the pressing part to open under the action of the pulling force.

[0009] As a preferred embodiment, the pressing buckle further includes a rotating arm and a fixed block. The reset structure is a reset spring, which ensures that the pressing block always has a pressing tendency. The pressing block is mounted on the rotating arm, and the fixed block is used to install the pressing buckle on the material tray. A linkage mechanism is provided between the rotating arm and the fixed block. A pull rod is vertically movably mounted on the fixed block, and the upper end of the pull rod is hinged to the rotating arm. The reset spring is sleeved on the pull rod and is located between the fixed part and the rotating arm. The pull rod pulls the rotating arm to flip open through the linkage mechanism, thereby causing the pressing block to perform an opening action.

[0010] As a preferred embodiment, the pressing buckle further includes a fixing block, which is used to install the pressing buckle on the material tray. A pressing guide rod is provided between the pressing block and the fixing block. The pressing block is movably connected to the fixing block through the cooperation of the pressing guide rod and the pressing guide sleeve. The pull rod is arranged laterally and connected to the pressing block. The reset structure is a reset spring provided between the pressing block and the fixing block. The reset spring ensures that the pressing block always has a pressing tendency. The pull rod drives the pressing block to move laterally to perform the opening action.

[0011] As a preferred embodiment, the pressing buckle further includes a fixing block, which is used to install the pressing buckle on the material tray. A pressing guide rod is provided between the pressing block and the fixing block. The pressing block is movably connected to the fixing block through the cooperation of the pressing guide rod and the pressing guide sleeve. The pull rod is arranged laterally and connected to the pressing block. The reset structure is a magnetic block provided on the material tray and the pressing block. The magnetic block makes the pressing block always have a pressing tendency. The pressing block is driven by the pull rod to move laterally to perform the opening action.

[0012] As a preferred embodiment, the force-receiving part is a push rod, which drives the pressing part to perform an opening action under the action of the pushing force.

[0013] As a preferred embodiment, the pressing buckle further includes a rotating arm and a fixed block. The reset structure is a reset spring, which ensures that the pressing block always tends to press. The pressing block is mounted on the rotating arm. The fixed block is used to mount the pressing buckle on the material tray. The upper end of the fixed block extends integrally into a cylindrical part. The cylindrical part has a vertically arranged through hole that extends downward to the lower surface of the fixed block. The side of the cylindrical part is provided with a spiral track that communicates with the through hole. A push rod extends upward from the lower surface of the fixed block through the through hole and is fixedly connected to the rotating arm. The push rod is movably connected to the cylindrical part through the through hole. The side of the push rod is provided with a slider corresponding to the spiral track. A compression spring is sleeved on the push rod and located between the fixed block and the handle of the push rod. The push rod controls the rotation of the rotating arm through the spiral track, thereby driving the pressing block to rotate and perform the opening action.

[0014] A baking feeding device using the above-mentioned clamp includes a frame, an opening and closing assembly, and a flipping mechanism. The clamp is placed on the frame, the opening and closing assembly is used to provide external force to the clamp to drive the force-receiving part, and the flipping mechanism is used to flip the clamp.

[0015] As a preferred embodiment, the opening and closing assembly includes an opening and closing platform, which is fixedly mounted on the frame and has a pressing station. Before the material is loaded and pressed, the fixture is placed in the pressing station.

[0016] As a preferred embodiment, the opening and closing assembly further includes an opening and closing block, a positioning cylinder for controlling the lateral / vertical movement of the opening and closing block, and an opening and closing cylinder for driving the opening and closing block to perform traction / pushing actions.

[0017] As a preferred embodiment, the flipping mechanism includes a gripping assembly for gripping the material tray and a flipping assembly for flipping the material tray; the gripping assembly includes two opposing gripping arms and a gripping cylinder for driving the two gripping arms to move relative to each other, a clearance space corresponding to the material tray is formed between the two gripping arms, and each of the two gripping arms is provided with a rotatable gripping block; the flipping assembly includes a transmission device and a flipping motor, and the flipping motor drives the gripping block to rotate through the transmission device.

[0018] The beneficial effects of this invention are as follows: The frame-shaped tray exposes both sides of the material, and the edges of the material are pressed together by the clamping buckle. The clamping buckle ensures that the material being baked is in a stable stress state, thus providing better protection for the precision circuit board assemblies or semiconductor wafers being baked. Furthermore, the integrated design of the clamp and the material being baked allows the material to move with the tray. A flipping mechanism flips the material and the automatic pressing assembly from a flat position to an upright position, sending them together into the oven. This avoids secondary transfer and prevents damage to the precision parts of the material due to impacts or deformation of the middle part during baking. It also avoids direct contact between external equipment and the material being baked during the baking and handling processes. Attached Figure Description

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0040] First, let's explain the baking fixture for stable engagement:

[0041] Example 1, as Figure 1-2 As shown, this utility model discloses a stable locking baking fixture, including a material tray 21 and a pressing buckle 22 disposed on the edge of the material tray 21; the material tray 21 has a frame structure, through which the front and back sides of the material 50 to be baked are exposed; the pressing buckle 22 includes a pressing block 221, a force-receiving part and a reset structure. Under the action of external force, the force-receiving part drives the pressing buckle 22 to perform an opening action. When the external force disappears, the reset structure is used to drive the pressing buckle 22 to be in a pressing state, and maintains a continuous pressing action after pressing. The pressing block 221 is used to press the material 50 onto the edge of the material tray 21 and fix the material 50 on the material tray 21, so that the material 50 can move with the movement of the material tray 21.

[0042] The pressing buckle 22 includes a pressing block 221, a rotating arm 222, a return spring 223 that keeps the pressing block 221 in a pressing tendency, a force-receiving part for pulling the rotating arm 222 to flip open, and a fixing block. The fixing block includes a fixing member 225 and a mounting member 226. The pressing block 221 is disposed on the rotating arm 222. The return spring 223 is drivenly connected to the rotating arm 222. The force-receiving part is drivenly connected to the rotating arm 222. A pressing strip 211 corresponding to the pressing block 221 is provided on the inner upper surface of the material tray 21. When pressing the material 50, the pressing block 221 and the pressing strip 211 press and fix the edges of the upper and lower surfaces of the material 50 under the action of the return spring 223. The pressing buckle 22 is detachably installed on the material tray 21 through the fixing member 225.

[0043] In this embodiment, the fixing member 225 is a horizontal block, the mounting member 226 is an L-shaped block, the fixing member 225 and the mounting member 226 are fixedly connected by a mortise and tenon structure, the edge of the material tray 21 is provided with a first clearance groove 212 corresponding to the mounting member 226, and after the fixing member 225 and the mounting member 226 are mortised, the fixing member 225 is located in the first clearance groove 212.

[0044] In this embodiment, the force-bearing part is a pull rod 224, and the return spring 223 is a compression spring. The pull rod 224 extends vertically upward and is mounted on the mounting member 226. The pull rod 224 is slidably connected to the mounting member 226. The pressure block 221 is provided at one end of the rotating arm 222 facing the inner side of the loading tray 21. The other end of the rotating arm 222 is hinged to the upper end of the pull rod 224. A connecting rod 227 is provided between the upper end of the mounting member 226 and the rotating arm 222. The two ends of the connecting rod 227 are... The mounting component 226 and the rotating arm 222 are not hinged together. The return spring 223 is sleeved on the pull rod 224 and is located between the mounting component 226 and the rotating arm 222. A washer 228 is provided between the return spring 223 and the rotating arm 222. When the pull rod 224 is pulled down, the pull rod 224 drives one end of the rotating arm 222 to rotate downward, and presses down the return spring 223 through the washer 228. The other end of the rotating arm 222 drives the pressure block 221 to flip upward. The return spring 223 drives the pressure block 221 to press the material 50. The material 50 is pressed by the pressure block 221. The material 50 is pressed by the pressure block 221. The material 50 has a long service life, simplifies the overall structure of the pressing buckle 22, reduces the space occupied by the pressing buckle 22, and is easy to replace. When the pull rod 224 pulls the rotating arm 222, the rotating arm 222 can be flipped upward by 90 degrees or even greater angle through the connecting rod 227, so that the pressing buckle 22 is fully opened, which makes it easy to put in the material 50 and avoids the material 50 from bumping against the rotating arm 222 during the process of putting in the material 50. Under the elastic force of the compression spring, the pressure block 221 always tends to press, and after the pressure block 221 is pressed, it always maintains the pressing action.

[0045] The upper inner edge of the loading tray 21 is provided with a chamfer to facilitate the placement of material 50.

[0046] In this embodiment, the material tray 21 is formed by splicing four frame edges. In actual use, the material tray 21 can also be integrally formed.

[0047] Example 2, as Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the pressing buckle 22 includes a pressing block 221, a rotating arm 222, a return spring 223 that keeps the pressing block 221 in a pressing tendency, a push rod 229 for driving the rotating arm 222 to rotate, and a fixing block.

[0048] In this embodiment, the return spring 223 is a compression spring, the push rod 229 is vertically arranged, the pressure block 221 is arranged on the rotating arm 222, and the fixing block is used to install the pressing buckle 22 on the material tray 21. The fixing block includes a fixing member 225, the upper end of which integrally extends out of the cylindrical part 2251. The cylindrical part 2251 has a vertically arranged through hole that extends downward to the lower surface of the fixing member 225. The side of the cylindrical part 2251 is provided with a spiral track 2252 that communicates with the through hole. The push rod 229 extends upward from the lower surface of the fixing member 225 through the through hole and is fixedly connected to the rotating arm 222. The push rod 229 is movably connected to the cylindrical part 2251 through the through hole. The side of the push rod 229 is provided with a slider 2291 corresponding to the spiral track 2252. The compression spring is sleeved on the push rod 229 and is located between the fixing member 225 and the... Between the handle 2241 of the push rod 229, the arc angle corresponding to the spiral track 2252 is set to be greater than or equal to 90 degrees. The push rod 229 controls the rotating arm 222 to rotate 90 degrees or more through the spiral track 2252, thereby causing the pressing block 221 to move and perform the opening action, fully opening it to facilitate the insertion of material 50 and avoid collision between material 50 and rotating arm 222 during the insertion process. After the material 50 is placed in the loading tray 21, the remaining external force is removed, and the push rod 229 moves downward under the elastic force of the compression spring. Through the cooperation of the slider 2291 and the spiral track 2252, it rotates obliquely downward by greater than or equal to 90 degrees to perform the pressing action, pressing the edge of material 50 together. Under the elastic force of the compression spring, the pressing block 221 always has a tendency to press together, and the pressing action is maintained after the pressing block 221 is pressed together.

[0049] Example 3, as Figure 4 As shown, the difference between this embodiment and the above embodiment is that the pressing buckle 22 includes a pressing block 221, a return spring 223, a pull rod 224 and a fixing block. The pull rod 224 is arranged horizontally and connected to the fixing block. A pressing guide rod 2211 is provided between the pressing block 221 and the fixing block. The pressing block 221 is movably connected to the fixing block through the cooperation of the pressing guide rod 2211 and the pressing guide sleeve 2253. The return spring 223 is provided between the pressing block 221 and the fixing block.

[0050] In this embodiment, the reset spring 223 is a compression spring, and the fixing block includes a fixing member 225. The fixing member 225 is disposed on the rear side of the pressing block 221. The pressing guide rod 2211 extends laterally and is disposed on the rear side of the pressing block 221. The pressing guide sleeve 2253 is disposed on the fixing member 225. The pressing block 221 is movably connected to the fixing member 225 through the cooperation of the pressing guide rod 2211 and the pressing guide sleeve 2253. The compression spring is sleeved on the pressing guide rod 2211. Under the elastic force of the compression spring, the pressing block 221 always has a tendency to press, and the pressing action is always maintained after the pressing block 221 is pressed. When the pressing buckle 22 is opened, the pressing block 221 is driven to move laterally by the pull rod 224 to perform the opening action.

[0051] Example 4, as Figure 5 As shown, the difference between this embodiment and Embodiment 3 is that the reset spring 223 is a tension spring, which is disposed between the pressure block 221 and the fixing member 225. One end of the tension spring is connected to the fixing member 225, and the other end of the tension spring is connected to the pressure block 221. The guide rod 2211 extends laterally and is disposed on the front side of the fixing member 225. The pressing guide sleeve 2253 is disposed on the pressure block 221. The pressure block 221 is movably connected to the fixing member 225 through the cooperation of the pressing guide rod 2211 and the pressing guide sleeve 2253. Under the tension of the pressure spring, the pressure block 221 always has a tendency to press, and always maintains the pressing action after the pressure block 221 is pressed.

[0052] Example 5, such as Figure 6 and Figure 7 As shown, the difference between this embodiment and embodiment three is that the reset structure is a magnetic block set on the fixing member 225 and the pressure block 221. The pressure block 221 always has a tendency to be pressed by the action of the magnetic block.

[0053] In this embodiment, the magnetic block is a magnet 28 that is disposed opposite to the pressing block 221 and the fixing member 225. The two magnets 28 are opposite to each other with the same poles and repel each other. Under the action of magnetic repulsion, the pressing block 221 is always subjected to a lateral force, so that the pressing block 221 always has a tendency to press and close, and always maintains the pressing action after the pressing block 221 is pressed.

[0054] Example 6, as Figure 8 and Figure 9 As shown, the difference between this embodiment and embodiment five is that the pressing block 221 always has a tendency to be pressed together through magnetic adsorption.

[0055] In this embodiment, the fixing member 225 is disposed on the front side of the pressing block 221, and the magnetic block includes magnets 28 disposed opposite to each other on the pressing block 221 and the fixing member 225. The opposite poles of the two magnets 28 are opposite to each other and attract each other. Under the action of magnetic adsorption, the pressing block 221 is always subjected to a lateral force, so that the pressing block 221 always has a tendency to press, and the pressing block 221 always maintains the pressing action after pressing.

[0056] The baking feeding device is described below:

[0057] like Figure 1-17 As shown, an automatic pressing and flipping baking feeding device using the aforementioned clamp includes a frame 10, an opening and closing assembly, a flipping mechanism 30, an x, y, z linear motion mechanism 40 for controlling the flipping mechanism 30 to move along the x, y, z directions, and a baking rack 60 for vertically placing the material 50. The aforementioned clamp is placed on the frame 10. The opening and closing assembly is used to provide external force to the clamp to drive the force-receiving part. The flipping mechanism is used to flip the clamp. The material 50 is placed horizontally behind the aforementioned clamp. The clamp is used to press and fix the edge of the material 50 and expose both sides of the material 50. The flipping mechanism 30 flips the clamp and the material 50 from a horizontal state to an upright state.

[0058] In this embodiment, the material 50 is transferred into the loading tray 21 by suction cup adsorption. The suction cup adsorption of material 50 is a conventional method of material handling and is not a key technical point of this technical solution. Therefore, the suction cup adsorption of material 50 will not be described in detail.

[0059] like Figure 11-14 As shown, the opening and closing assembly includes an opening and closing platform 23, an opening and closing block 24, a positioning cylinder 25, an opening and closing cylinder, and a first mounting plate 27. The opening and closing platform 23 is fixedly mounted on the frame 10. The opening and closing platform 23 has a pressing station 231, and the pressing station 231 has a positioning groove 213 opposite to the material tray 21. When the material is pressed, the material tray 21 is placed into the positioning groove 213. For ease of understanding, the fixture of Embodiment 1 is used as a supporting description to facilitate understanding of the working principle of the baking feeding device. When the force-bearing part of the pressing buckle 22 is a vertically arranged pull rod 224 (refer to...), Figure 2The positioning cylinder 25 is mounted on the first mounting plate 27, and the output end of the positioning cylinder 25 is driven to the opening and closing block 24. The opening and closing cylinder is a traction cylinder 26 used to drive the opening and closing block 24 to perform traction action. The traction cylinder 26 is mounted on the frame 10, and the output end of the traction cylinder 26 is driven to the first mounting plate 27. The lower end of the pull rod 224 is provided with a handle 2241. The opening and closing block 24 is provided with a slot 241 corresponding to the handle 2241. During operation, the positioning cylinder 25 drives the opening and closing block 24 to move laterally, so that the slot 241 is locked above the handle 2241. The traction cylinder drives the opening and closing block 24 to move downward. The pull rod 224 is pulled by the cooperation of the slot 241 and the handle 2241.

[0060] In practical applications, in addition to using the return spring 223 to drive the pressure block 221 to press the material 50, it can also be achieved by means of cylinders or rubber bands.

[0061] The opening and closing platform 23 is provided with a downwardly extending guide rod 233, and the first mounting plate 27 is provided with a guide sleeve 271 corresponding to the guide rod 233. The first mounting plate 27 is slidably connected to the guide rod 233 through the guide sleeve 271.

[0062] To prevent the movable rod of the positioning cylinder 25 from being deformed by force when the pull rod 224 is pulled down, the first mounting plate 27 is provided with a slide rail 272. The opening and closing block 24 is set on the slide rail 272 and slidably connected to the slide rail 272. During operation, the positioning cylinder 25 drives the opening and closing block 24 to slide along the slide rail 272.

[0063] When the force-bearing part of the aforementioned snap fastener 22 is a horizontally arranged pull rod 224 (refer to...) Figures 4 to 9 The opening and closing cylinder is a traction cylinder (not shown) used to drive the opening and closing block 24 to perform traction action. The end of the pull rod 224 away from the pressure block 221 is provided with a handle 2241. The opening and closing block 24 is provided with a slot 241 corresponding to the handle 2241. During operation, the positioning cylinder 25 drives the opening and closing block 24 to move vertically, so that the slot 241 is engaged with the front end of the handle 2241. The traction cylinder drives the opening and closing block 24 to move laterally outward. The pull rod 224 is pulled by the cooperation of the slot 241 and the handle 2241.

[0064] When the force-bearing part of the aforementioned snap fastener 22 is a vertically arranged push rod 229 (refer to...) Figure 3 The opening and closing cylinder is a push cylinder (not shown) used to drive the opening and closing block 24 to perform a pushing action. The lower end of the pull rod 224 is provided with a handle 2241. During operation, the positioning cylinder 25 drives the opening and closing block 24 to move laterally, so that the opening and closing block 24 moves to the lower end of the handle 2241. The push cylinder drives the opening and closing block 24 to move vertically upward. The push rod 229 is pushed by the cooperation between the opening and closing block 24 and the handle 2241.

[0065] like Figure 15-17 As shown, the flipping mechanism 30 includes a gripping assembly for gripping the material tray 21, a flipping assembly for flipping the material tray 21, and a second mounting plate 31. The gripping assembly includes two opposing gripping arms 32 and a gripping cylinder 33 for driving the two gripping arms 32 to move relative to each other. A clearance space corresponding to the material tray 21 is formed between the two gripping arms 32. The opening and closing platform 23 is provided with a second clearance groove 232 corresponding to the gripping arms 32. Each of the two gripping arms 32 is provided with a rotatable gripping block 321. Each of the two gripping blocks 321 is provided with a gripping groove 3211. The two gripping grooves 3211 are arranged opposite to each other. The material tray 21 is provided with a positioning groove 213 corresponding to the gripping groove 3211. When the gripping arms 32 grip the material tray 21, the gripping arms 32 extend into the second clearance groove 232, and the two gripping blocks 321 grip the material tray 21 from the edge of the positioning groove 213 through the gripping groove 3211.

[0066] The flipping assembly includes a transmission device and a flipping motor 34. The flipping motor 34 drives the clamping block 321 to rotate via the transmission device. In this embodiment, the transmission device includes a first transmission belt 35, a transmission rod 36, and a second transmission belt 37. The clamping cylinder 33, the first transmission belt 35, and the flipping motor 34 are all mounted on the second mounting plate 31. The two clamping arms 32 are each equipped with the second transmission belt 37. The first transmission belt 35 is driven to connect with the second transmission belt 37 via the transmission rod 36. The second transmission belt 37 on each clamping arm 32 is driven to connect with the clamping block 321 of its respective clamping arm 32. The flipping motor 34 drives the clamping block 321 to rotate through the cooperation of the first transmission belt 35, the transmission rod 36, and the second transmission belt 37. By integrating the flipping assembly and the clamping assembly into one unit, the space occupied by the flipping mechanism 30 is reduced.
