Description

Technical Field

[0001] This utility model relates to the field of PTC heater processing technology, specifically to an alumina plate positioning fixture. Background Technology

[0002] In the manufacturing process of PTC heaters, the surface of the alumina insulating substrate needs to be uniformly coated with adhesive. Because the substrate is thin and the surface is covered with adhesive after application, operators easily get adhesive on their hands when handling it manually, resulting in missing adhesive areas and affecting bonding quality. Current technology lacks specialized tools for safely and efficiently handling the substrate, leading to low work efficiency and high defect rates. Therefore, a mechanism is needed that can stably lift the substrate without contacting the adhesive surface, facilitating easy handling. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an alumina plate positioning fixture, which realizes the positioning of the alumina plate, makes the alumina plate easy to handle, and improves efficiency.

[0004] Specifically, this utility model discloses an alumina plate positioning fixture, comprising:

[0005] A base plate is used to support the product, and baffles are provided on the sides of the base plate;

[0006] The positioning component includes multiple positioning pins mounted on the base plate for lifting one end of the product.

[0007] A drive component, connected to the positioning pin, is used to drive the positioning pin to move up and down.

[0008] The advantages of adopting the above technical solution are that the positioning pin lifts one side of the product, making it easier to pick up the product, improving the efficiency of substrate coating, avoiding direct contact with the adhesive surface when picking up the product manually, effectively reducing the risk of missing adhesive on the substrate, and thus improving the coating quality.

[0009] Furthermore, the positioning pin is cylindrical, and the top of the positioning pin has a step.

[0010] The advantage of adopting the above technical solution is that the step is used to lift the side of the product to form a slope. This step provides support after being lifted, making the product tilted and easy to pick up.

[0011] Furthermore, the top of the positioning pin is provided with a mounting component, which is horizontally fixed and positioned along the width direction of the product to be processed.

[0012] The advantage of adopting the above technical solution is that the mounting component is set on the top of the product to form a support. It is set along the width direction and contacts the lower surface of the product, which can effectively prevent the product from tilting to the side and avoid the product from slipping.

[0013] Furthermore, the base plate is provided with staggered positioning blocks and staggered positioning pins. The positioning blocks limit one end of the product, and the positioning pins lift the other end of the product.

[0014] The advantage of adopting the above technical solution is that when the product is placed on the base plate, the positioning block can limit the product from the edge of one end, effectively preventing the product from shifting laterally during the lifting process; while the staggered positioning pins apply force evenly from the bottom of the other end of the product, ensuring a smooth lifting action. This staggered distribution can increase the number of products that can be placed in a limited space, and the two ends of adjacent products are lifted in an alternating manner, so that not much space is needed between the two products.

[0015] Furthermore, the top of the mounting component has an arc-shaped surface.

[0016] The advantage of adopting the above technical solution is that the curved surface can stably lift the product during the ejection process, while ensuring a smooth lifting process without damaging the product surface, thus effectively protecting the product surface.

[0017] Furthermore, the drive assembly includes a cylinder and a connector. The connector is connected to the output end of the cylinder and is located on the underside of the base plate. It is connected to the positioning pin and drives the positioning pin to move up and down.

[0018] The advantage of adopting the above technical solution is that by setting a cylinder to control the positioning pin, the positioning pin can be driven to rise and fall. The positioning pin can be in a retracted state before applying glue and extended after applying glue, or it can always be in an extended state. It can be set according to production needs, making it convenient to pick up and meet different production needs.

[0019] Furthermore, the positioning pin includes a body and a buffer block. The top of the buffer block is provided with a receiving groove, and a spring is installed in the receiving groove. The bottom of the body has a main body groove for receiving the buffer block. The top of the buffer block extends into the main body groove, and the top of the spring contacts the main body groove.

[0020] The advantage of adopting the above technical solution is that the retractable main body can provide elastic buffer during the process of the positioning pin lifting the product. When the positioning pin contacts the product and gradually rises, the spring will absorb the excess impact force through its own compression deformation, avoiding rigid contact that could cause indentations or damage to the product surface, effectively improving the stability of the positioning process and the protection of the product.

[0021] Furthermore, the main body has strip-shaped holes on both sides, and the buffer block has protrusions on both sides. The main body floats up and down along the buffer block, and the protrusions are used to limit the main body.

[0022] The advantage of adopting the above technical solution is that the strip hole and the protrusion block work together to limit the range of the body's vertical movement. When the body moves upward along the buffer block, the protrusion block slides in the strip hole until the bottom of the strip hole contacts the protrusion block, thereby preventing the body from continuing to rise and preventing the body from separating from the buffer block. When the body moves downward, the top of the strip hole contacts the protrusion block, limiting the body from moving too far downward and ensuring that the spring is always in a reasonable compression range, avoiding the failure of the buffer function or damage to components due to uncontrolled stroke.

[0023] Furthermore, a support rod is provided at the bottom of the base plate.

[0024] The advantage of adopting the above technical solution is that the support rod is used to fix the base plate, which is fixed on the workbench or the frame of the glue application equipment. The base plate is easy to move and is suitable for different usage scenarios.

[0025] Furthermore, a protective layer is provided at the upper end of the positioning pin.

[0026] The advantage of adopting the above technical solution is that the protective layer can play a protective role and avoid damage to the product. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] like Figure 1-3 As shown, this utility model discloses an alumina plate positioning fixture, comprising:

[0037] A base plate 1 is used to support the product. A baffle 2 is provided on the side of the base plate 1. The baffle 2 is fixedly installed around the base plate 1 to provide protection.

[0038] The positioning component includes multiple positioning pins 3 disposed on the base plate 1, which are used to lift one end of the product.

[0039] The driving component 4 is connected to the positioning pin 3 and is used to drive the positioning pin 3 to rise and fall. During the processing, the positioning pin 3 can always be in the extended state to facilitate the picking and placing of products. Alternatively, the positioning pin 3 can be in the retracted state before the glue is applied and then rise after the glue is applied to facilitate the removal of products.

[0040] The advantages of adopting the above technical solution are that the positioning pin 3 lifts one side of the product, making it easier to pick up the product, improving the efficiency of substrate coating, avoiding direct contact with the adhesive surface when picking up the product manually, effectively reducing the risk of missing adhesive on the substrate, and thus improving the coating quality.

[0041] In some implementations, the positioning pin 3 is cylindrical, and the top of the positioning pin 3 has a step 31. The edge of the step 31 and the edge of the positioning pin 3 form a slope, which supports the product. Multiple guide holes are provided on the base plate 1 to facilitate changing the position of the positioning pin 3 and to be suitable for products of different sizes.

[0042] In some implementation schemes, such as Figure 4 As shown, the top of the positioning pin 3 is provided with a mounting part 32. The mounting part 32 is horizontally fixedly installed on the top of the positioning pin 3 and is set along the width direction of the product to be processed. A groove can be opened on the base plate 1 to accommodate the mounting part 32, so that the mounting part 32 is located in the mounting groove after the positioning pin 3 is retracted, and the base plate 1 is a plane. The top of the mounting part 32 has an arc-shaped surface. During the lifting process, the arc-shaped surface contacts the bottom of the product, reducing scratches on the product surface.

[0043] Furthermore, the base plate 1 is provided with staggered positioning blocks 5, which are fixedly installed on the base plate 1. Positioning pins 3 are staggered. The positioning blocks 5 limit one end of the product, and the positioning pins 3 lift the other end of the product. This staggered distribution can maximize the utilization area in the limited space of the base plate 1, so that the non-lifted end and the lifted end of the adjacent products are staggered, effectively reducing the interval between products, so that more products can be placed at the same time and improving processing efficiency.

[0044] When multiple alumina plates are placed side by side on the base plate 1, the left end of the first product is limited by the positioning block 5 and the right end is lifted by the positioning pin 3. The right end of the second product is limited by the positioning block 5 and the left end is lifted by the positioning pin 3. The lifting end and the limiting end of the adjacent products are staggered, which avoids the problem of excessive distance between the two ends of the products in the traditional same-direction lifting method, and also makes it convenient to remove the products.

[0045] Furthermore, the drive assembly 4 includes a cylinder and a connector 41. The connector 41 is connected to the output end of the cylinder. The main body 33 of the cylinder can be fixed to the side or bottom of the base plate 1 as needed. The connector 41 is located on the lower side of the base plate 1 and is fixedly connected to the positioning pin 3, driving the positioning pin 3 to rise and fall. The position of the positioning pin 3 installed on the connector 41 can be adjusted. Since the base plate 1 has multiple arrayed guide holes, the position of the positioning pin can be adjusted to suit the processing of products of different sizes.

[0046] Furthermore, such as Figure 5 As shown, the positioning pin 3 includes a main body 33 and a buffer block 6. The top of the buffer block 6 is provided with a receiving groove, and a spring 61 is installed in the receiving groove. The bottom of the main body 33 has a main body groove 34 for receiving the buffer block 6. The top of the buffer block 6 extends into the main body groove 34, and the top of the spring 61 contacts the main body groove 34 and the bottom contacts the bottom of the receiving groove.

[0047] The main body 33 has strip-shaped holes 62 on both sides, and the buffer block 6 has protrusions 63 on both sides. The protrusions 63 can be locked onto the buffer block 6. The main body 33 floats up and down along the buffer block 6 under the support of the spring 61. The protrusions 63 limit the position of the main body 33 so that the main body 33 will not detach during the up and down floating process.

[0048] Furthermore, a support rod 11 is provided at the bottom of the base plate 1. A detachable support foot can be installed at the bottom of the support rod 11. When applying glue manually, the base plate 1 is placed on the workbench and supported by the support foot. If applying glue automatically, the support foot is fixed to the glue application equipment. It can be moved to different positions according to different usage needs, which is highly flexible.

[0049] Furthermore, a protective layer is provided at the upper end of the positioning pin 3 to prevent scratching the product. The protective layer can be made of materials such as rubber.

[0050] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
