Description

Technical Field

[0001] This utility model relates to the field of substrate feeding technology, and in particular to a substrate pushing device. Background Technology

[0002] Existing substrate feeding methods typically employ push-in with push rods or pull-in with chucks. For push-in structures, current designs usually use a fixed pusher head that pushes the substrate into the center. However, when the substrate deforms, it may miss the pusher. For example, a normal substrate will arch upwards when heated, while an ultrathin substrate will naturally bend and droop even when not heated. In this case, the contact point between the pusher head and the substrate will misalign, leading to missed pushes and scraping. Therefore, existing fixed pusher heads have poor compatibility, high risks, and cannot meet the requirements for ultrathin substrates. Utility Model Content

[0003] The purpose of this invention is to provide a substrate pushing device that aims to solve the technical problems of poor compatibility, high risk, and inability to meet the requirements of ultra-thin substrates in existing fixed pushers.

[0004] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0005] This utility model provides a substrate pushing device, including: a housing, a push rod and two push claws. The push rod is fixedly connected to the housing. The housing is provided with a mounting cavity. The two push claws are arranged opposite to each other and are movably installed in the mounting cavity. The length of the push claws extending into the mounting cavity is adjusted to change the distance between the two push claws.

[0006] Furthermore, the pusher includes an adjustment part and a pushing part. One end of the adjustment part is movably disposed inside the mounting cavity, and the other end is located outside the mounting cavity and connected to the pushing part.

[0007] Furthermore, the pusher is L-shaped, the adjusting part is a horizontal rod, the pushing part is a vertical rod, the adjusting part is provided with several inclined ratchet bars, the ratchet bars are evenly distributed on the top of the adjusting part, and a limit slot is formed between two adjacent ratchet bars.

[0008] Furthermore, the substrate pushing device also includes a limiting component, which is located in the mounting cavity and fixedly connected to the housing. The limiting component is movably connected to the pusher claw to restrict the movement of the pusher claw.

[0009] Furthermore, the limiting component includes a limiting pawl, a leaf spring, and a connecting member. The limiting pawl is fixedly connected to the leaf spring, the leaf spring abuts against the housing, and the limiting pawl is connected to the housing through the connecting member.

[0010] Furthermore, the limiting pawl includes a connecting part and a limiting part. The connecting part is a through hole that passes through one end of the limiting pawl. The connecting member is connected to the connecting part so that the housing is connected to the limiting pawl. The limiting part cooperates with the limiting slot.

[0011] Furthermore, the ratchet is inclined toward the pushing part, and the direction of the limiting part is opposite to the direction of the ratchet.

[0012] Furthermore, when the connector is installed on the housing, the ratchet engages with the limiting pawl, and the two pushers can move unidirectionally toward the push rod to reduce the distance between the two pushers; when the connector is not installed, the two pushers can move bidirectionally to reduce or increase the distance between the two pushers.

[0013] Furthermore, the pushing part has a groove, the size of which is adapted to the size of the substrate.

[0014] Furthermore, the substrate pushing device also includes a buffer member, which is made of elastic material and is adjustablely disposed in the groove.

[0015] The advantages of this invention compared to existing technologies are as follows: This invention designs an adjustable-distance substrate pushing device, in which the pusher claws are movably positioned within the mounting cavity. By changing the length of the pusher claws extending into the mounting cavity, the distance between the two pusher claws can be adjusted, thereby adapting to different substrate sizes. Compared to existing fixed pusher head structures, which cannot cope with misalignment and scratching problems caused by substrate deformation, and cannot meet the adaptation requirements under frequent changes in substrate specifications, this invention adopts an adjustable-distance structure, which can move the contact point between the pusher head and the substrate to the edge, effectively solving the misalignment problem. It can also accommodate substrates of different widths, eliminating the need for frequent adjustments to the machine compensation settings, saving time and effort. Attached Figure Description

[0026] Please see Figures 1 to 3 This utility model discloses a substrate pushing device, including: a housing 1, a push rod 2 and two push claws 3. The push rod 2 is fixedly connected to the housing 1. The housing 1 is provided with a mounting cavity 11. The two push claws 3 are arranged opposite to each other and are movably installed in the mounting cavity 11. The length of the push claws 3 extending into the mounting cavity 11 is adjusted to change the distance between the two push claws 3.

[0027] Specifically, the housing 1, as the main structure of the device, possesses sufficient strength and rigidity to support other components and protect the internal mechanisms. The push rod 2 is fixedly connected to the housing 1 to transmit thrust, enabling the push claw 3 to move and push the substrate. In this embodiment, the push rod 2 is fixed to the housing 1 by bolts, welding, or other means. Furthermore, in this embodiment, there are two push claws 3, used to directly contact and push the substrate. The push claws 3 are installed in the mounting cavity 11 of the housing 1 via a movable connection such as sliding or rotating, allowing adjustment of the distance between the two push claws 3. By adjusting the distance between the two push claws 3, the device can adapt to substrates of different widths or sizes, improving the versatility and flexibility of the equipment. Adjusting the distance between the push claws 3 is relatively simple and can be done manually or automatically, reducing operational difficulty and labor costs.

[0028] Working principle: When the substrate needs to be pushed, the push rod 2 is driven by an external force (such as human power, cylinder, motor, etc.), which drives the push claw 3 to move together. The distance between the push claws 3 is adjusted according to the size of the substrate to ensure that the substrate can be firmly clamped and pushed.

[0029] like Figure 2 As shown, the pusher 3 includes an adjustment part 31 and a pushing part 32. One end of the adjustment part 31 is movably disposed in the mounting cavity 11, and the other end is located outside the mounting cavity 11 and connected to the pushing part 32.

[0030] Specifically, the adjusting part 31 is the portion of the pusher 3 used to adjust its position and distance. One end of it is movably disposed within the mounting cavity 11 of the housing 1, allowing it to move within a certain range. The other end is located outside the mounting cavity 11 and connected to the pushing part 32. The pushing part 32 is the portion of the pusher 3 directly used to contact and push the substrate. It typically has an appropriate shape and size to ensure effective clamping and pushing of the substrate. The pushing part 32 and the adjusting part 31 are securely connected by means such as bolts, welding, or riveting to ensure they do not separate during the pushing process. When the pusher 2 is subjected to an external driving force, it will drive the adjusting part 31 and the pushing part 32 to move together. Since the adjusting part 31 is movable, its position can be adjusted as needed to accommodate substrates of different sizes. The pushing part 32 directly contacts the substrate and pushes it to the designated position through friction or clamping force.

[0031] like Figure 2 As shown, the pusher 3 is L-shaped, the adjustment part 31 is a horizontal rod, the push part 32 is a vertical rod, the adjustment part 31 is provided with a number of inclined ratchet 311, the ratchet 311 is evenly distributed on the top of the adjustment part 31, and a limit slot 312 is formed between two adjacent ratchet 311.

[0032] Specifically, in this embodiment, the pusher 3 is L-shaped and consists of a horizontal adjustment part 31 and a vertical pushing part 32. This design allows the pusher 3 to adapt to both horizontal and vertical movement requirements. The adjustment part 31, acting as a horizontal rod, primarily functions to connect and adjust. One end is movably disposed within the mounting cavity 11 of the housing 1, allowing it to move within a certain range to accommodate substrates of different sizes, while the other end is securely connected to the pushing part 32. The pushing part 32, acting as a vertical rod, directly contacts and pushes the substrate, and its length and shape are designed according to the specific dimensions of the substrate and the pushing requirements.

[0033] Furthermore, the top of the adjusting part 31 is provided with several inclined ratchet bars 311. These ratchet bars 311 are evenly distributed, forming a ratchet-like structure, but here they are used for positioning and limiting, rather than transmission. Limiting slots 312 are formed between adjacent ratchet bars 311. These limiting slots 312 allow the adjusting part 31 to be adjusted within the mounting cavity 11 in specific steps or positions, thereby precisely controlling the distance between the pushing parts 32. Through the design of the ratchet bars 311 and the limiting slots 312, the device achieves precise adjustment of the position of the pusher 3. The operator can easily adjust the distance between the pushing parts 32 as needed to accommodate substrates of different sizes.

[0034] like Figures 1 to 3 As shown, the substrate pushing device also includes a limiting component 4, which is located in the mounting cavity 11 and fixedly connected to the housing 1. The limiting component 4 is movably connected to the pusher 3 to limit the movement of the pusher 3.

[0035] Specifically, the limiting component 4 is located within the mounting cavity 11 of the housing 1 and is fixedly connected to the housing 1. This means that the limiting component 4 is a fixed part inside the device, used to limit the movement range of the pusher 3. The limiting component 4 and the pusher 3 are connected in a movable manner, allowing the pusher 3 to move within a certain range while restricting it from exceeding that range.

[0036] like Figures 1 to 3 As shown, the limiting component 4 includes a limiting pawl 41, a leaf spring 42, and a connecting member 43. The limiting pawl 41 is fixedly connected to the leaf spring 42, the leaf spring 42 abuts against the housing 1, and the limiting pawl 41 is connected to the housing 1 through the connecting member 43.

[0037] Specifically, the limiting pawl 41 is the main part of the limiting assembly 4, used to directly limit the movement range of the pusher 3. The limiting pawl 41 has a serrated or hook-shaped structure to cooperate with the ratchet 311 on the pusher 3 to form a limiting effect. The leaf spring 42 is an elastic element used to provide pressure between the limiting pawl 41 and the housing 1. When the adjusting part 31 of the pusher 3 moves, the leaf spring 42 absorbs the impact and keeps the limiting pawl 41 in a stable position. The connecting piece 43 is used to connect the limiting pawl 41 and the housing 1 to ensure that the limiting pawl 41 can be securely installed in the mounting cavity 11.

[0038] It is understood that the connector 43 in this embodiment is a bolt. In other embodiments, it may also be a rivet, a welded point or other form of mechanical connection, depending on the actual situation.

[0039] like Figure 1 and 2 As shown, the limiting pawl 41 includes a connecting part 411 and a limiting part 412. The connecting part 411 is a through hole that passes through one end of the limiting pawl 41. The connecting piece 43 is connected to the connecting part 411 so that the housing 1 is connected to the limiting pawl 41. The limiting part 412 is engaged with the limiting slot 312.

[0040] Specifically, the adapter 411 is one end of the limiting pawl 41, designed as a through hole. This through hole is used to mate with a connector 43 (such as a bolt, pin, etc.) to securely connect the limiting pawl 41 to the housing 1. The size and shape of the adapter 411 are typically designed according to the type and size of the connector 43 to ensure a good fit and connection strength. The limiting part 412 is the other end of the limiting pawl 41, with a specific shape and structure for mates with the limiting latch 312 on the pusher 3. The limiting part 412 is serrated, hook-shaped, or other shapes that can tightly mate with the limiting latch 312 to effectively prevent the pusher 3 from moving further when it reaches a specific position.

[0041] like Figure 2 As shown, the ratchet 311 is inclined toward the pushing part 32, and the direction of the limiting part 412 is opposite to the direction of the ratchet 311.

[0042] Specifically, the ratchet 311 is designed to tilt towards the pusher 32, meaning that the ratchet 311 is not perpendicular to the moving direction of the pusher 3, but forms an angle with it. This tilting design helps the pusher 3 gradually contact the limiting part 412 during its movement, thereby producing a gradual limiting effect. Opposite to the tilting direction of the ratchet 311, the limiting part 412 is designed to point to the side opposite to the tilt of the ratchet 311. Thus, when the ratchet 311 gradually contacts the limiting part 412, the limiting part 412 can effectively prevent the ratchet 311 (and the connected pusher 3) from continuing to move along its tilting direction, without restricting its movement in the opposite direction of its tilt, thereby achieving a unidirectional adaptive adjustment effect for the pusher 3.

[0043] like Figure 1 and Figure 2 As shown, when the connector 43 is installed on the housing 1, the ratchet 311 engages with the limiting pawl 41, and the two push pawls 3 can move unidirectionally in the direction of the push rod 2 to reduce the distance between the two push pawls 3; when the connector 43 is not installed, the two push pawls 3 can move bidirectionally to reduce or increase the distance between the two push pawls 3.

[0044] Specifically, when the connector 43 is installed on the housing 1, it functions as a fixed limiting pawl 41. At this time, the limiting portion 412 of the limiting pawl 41 is tightly engaged with the ratchet 311 on the pusher 3. This engagement restricts the movement direction of the pusher 3. With the connector 43 installed, due to the engagement between the ratchet 311 and the limiting pawl 41, the pusher 3 can only move unidirectionally towards the push rod 2. This means that the distance between the pushers 3 can only decrease, not increase. This unidirectional movement restriction ensures the stability and accuracy of the substrate during the pushing process. When the connector 43 is not installed, the limiting pawl 41 is in a free state and cannot engage with the ratchet 311. At this time, the pusher 3 can move bidirectionally, meaning it can both decrease and increase the distance between the pushers 3. This bidirectional movement capability makes the device more flexible during debugging, maintenance, or substrate replacement. The operator can easily switch the movement restriction state of the pusher 3 by installing or removing the connector 43. This design simplifies the operation process and improves work efficiency.

[0045] like Figure 1 and Figure 3 As shown, a groove 321 is provided on the pushing part 32, and the size of the groove 321 is adapted to the size of the substrate.

[0046] Specifically, in this embodiment, a groove 321 is specially formed on the pushing part 32. The dimensions of the groove 321 are precisely designed to ensure that it matches the size of the substrate to be pushed. This means that the width, depth, and length of the groove 321 are all matched with the corresponding dimensions of the substrate, thereby allowing the substrate to be tightly accommodated. The shape of the groove 321 is generally similar to the shape of the substrate to ensure that the substrate can be placed stably within the groove 321. For example, if the substrate is rectangular, then the groove 321 should also be rectangular, and its dimensions should be slightly larger than the dimensions of the substrate to facilitate easy insertion and removal of the substrate. The depth of the groove 321 is generally sufficient to accommodate a certain thickness of the substrate, while ensuring that the substrate does not slip or shift out of the groove 321 during the pushing process. The position of the groove 321 is located at the center or one side of the pushing part 32, depending on the pushing path of the substrate and the overall design of the device. The position of the groove 321 should ensure that the substrate can move smoothly during the pushing process without being unnecessarily obstructed.

[0047] like Figures 1 to 3 As shown, the substrate pushing device also includes a buffer 5, which is made of elastic material and is adjustablely disposed in the groove 321.

[0048] Specifically, the buffer 5 is adjustablely disposed within the groove 321. This means that the position, height, or shape of the buffer 5 can be adjusted as needed to accommodate substrates of different sizes or shapes. The buffer 5 can be fixed to the bottom, side, or any other location requiring cushioning within the groove 321 to ensure proper cushioning of the contact between the substrate and the pushing part 32 during the pushing process. The buffer 5 absorbs the impact force between the substrate and the pushing part 32, reducing vibration and friction of the substrate during the pushing process, thereby protecting the substrate from scratches, dents, or other forms of damage. By reducing the direct contact area and impact force between the substrate and the pushing part 32, the buffer 5 helps ensure that the substrate remains smooth and accurate during the pushing process. This contributes to improving the accuracy and reliability of the pushing process.

[0049] Furthermore, the buffer 5 is made of an elastic material, such as rubber, silicone, spring steel sheet, or other elastic materials. These materials have good resilience and cushioning properties, and can absorb impact and return to their original shape when subjected to external forces.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
