Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a carrier strip clamp and a coating fixture. Background Technology

[0002] In modern industrial production, many small parts require surface treatments, such as coating, to improve their performance and lifespan. However, for small parts to be coated, there are many challenges in carrying out the relevant processing.

[0003] Firstly, in the dispensing and masking process, the small size of the parts to be coated makes placing the dispensing fixtures extremely inconvenient. Operators need to spend a lot of effort and time accurately placing the fixtures, and even slight carelessness can lead to damage to the parts to be coated, resulting in material waste and increased production costs. Moreover, automated dispensing requires high precision. For small parts to be coated, their complex shape and tiny size make it difficult for automated dispensing equipment to accurately position them, leading to extended working hours, low production efficiency, and difficulty in meeting the needs of large-scale production.

[0004] Secondly, numerous problems also exist in the process of arranging the parts to be coated on the coating tray. Small parts are prone to sliding during tray placement, which not only consumes a lot of time for adjusting their position, but may also cause the parts to collide or shift during the coating process, thus affecting the uniformity and quality of the coating. This results in an unsatisfactory coating effect on the surface of the parts, or even incomplete or damaged coating, seriously affecting the final performance and appearance of the parts, reducing the pass rate of the coated parts, and causing economic losses to the enterprise.

[0005] In summary, for small-sized parts to be coated, there are many problems in the processes of dispensing and masking, coating tray placement, etc., such as inconvenient operation, easily damaged parts, high automation precision requirements and long processing time, and the impact of the sliding of the parts on the coating effect. These problems seriously restrict the improvement of production efficiency and the guarantee of the quality of the parts to be coated. There is an urgent need to find an effective solution to improve this situation and meet the requirements of modern industrial production for efficient and high-quality processing of small parts.

[0015] Optionally, the opening is a continuous opening along the extension direction of the cover plate, or the opening is composed of multiple sub-openings along the extension direction of the cover plate, and the sub-openings expose the non-coated area.

[0016] A coating fixture includes: a carrier assembly formed using the carrier clamp described above, the carrier assembly including a carrier strip, the carrier strip having a plurality of loading grooves arranged along its extension direction, the loading grooves being used to load a workpiece to be coated, the surface of the workpiece to be coated having a non-coating area; and a cover layer coated on the non-coating area.

[0017] Optionally, the cover layer includes an adhesive layer.

[0018] Optionally, it also includes a coating carrier frame having a slot corresponding to the carrier assembly, the slot being used to fix the carrier assembly.

[0019] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0031] For small parts that require masking with adhesive during coating, existing methods present several challenges: placing the adhesive dispensing fixture is inconvenient and prone to damage; automated dispensing requires high precision and is time-consuming; and the coating tray placement process is time-consuming and carries the risk of parts sliding and affecting the coating effect.

[0032] Based on this, the present invention provides a carrier strip clamp with several loading slots on the carrier strip for loading parts to be coated. The surface of the parts to be coated has a non-coated area. The clamp assembly includes a tray and a cover plate. The tray has several limiting slots arranged along its extension direction for loading the carrier strip. After the cover plate is placed on the tray, the opening on the cover plate exposes the non-coated area. In this way, several small parts to be coated are loaded onto the carrier strip to form a whole, realizing the dispensing of several parts to be coated at one time. This saves the time of taking the parts to be coated out of the clamp one by one, greatly reduces the tray placement time of the parts to be coated, increases the furnace loading capacity, improves the convenience and efficiency of operation, and reduces the risk of damage to the parts to be coated during loading.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Please refer to the reference. Figures 1 to 6 A carrier strip clamp 100 includes a carrier strip 101 and a clamp assembly 108.

[0035] In this embodiment, the carrier strip 101 has a plurality of loading grooves 102 arranged along its extending direction. The loading grooves 102 are used to load the workpiece 103 to be coated. The surface of the workpiece 103 to be coated has a non-coating area 103a. The clamp assembly 108 includes a tray 104 and a cover plate 105. The tray 104 has a plurality of limiting grooves 104a arranged along its extending direction. The limiting grooves 104a are used to load the carrier strip 101. The cover plate 105 has a plurality of openings 105a arranged along its extending direction. When the cover plate 105 covers the tray 104, the openings 105a expose the non-coating area 103a.

[0036] Figure 1 The dashed line indicates a one-to-one correspondence between the part to be coated 103 and the loading groove 102.

[0037] In this embodiment, the number of loading slots 102 is 6.

[0038] In other embodiments, the number of loading slots 102 can be other numbers, which can be set according to actual needs.

[0039] In this embodiment, the number of the parts to be coated 103 corresponds one-to-one with the number of the loading slots 102.

[0040] In this embodiment, please refer to Figure 3 The limiting groove 104a is arranged along the extending direction of the tray 104, that is... Figure 3 The middle arrow points to...

[0041] In other embodiments, the limiting groove 104a may also be arranged along a direction perpendicular to the extension of the tray 104.

[0042] In this embodiment, the loading groove 102 is engaged with the part to be coated 103.

[0043] In this embodiment, the sidewall 102a of the loading groove 102 and the sidewall 103b of the part to be coated 103 have matching shapes. After the part to be coated 103 is loaded into the loading groove 102, the protrusion 102b of the sidewall 102a of the loading groove 102 forms an elastic abutment with the sidewall of the part to be coated 103.

[0044] In this embodiment, several dispersed parts 103 to be coated are loaded into a whole using several loading slots 102 on the carrier strip 101, so as to achieve one-time dispensing of several parts 103 to be coated, saving the time of taking the parts 103 to be coated out of the fixture one by one, greatly reducing the time of placing the parts 103 to be coated on the tray, increasing the furnace loading capacity, improving the convenience and efficiency of operation, and reducing the risk of damage to the parts 103 to be coated during loading.

[0045] In this embodiment, please refer to Figures 4 to 7 The carrier strip 101, which carries the part to be coated 103, is placed into the limiting groove 104a, and the cover plate 105 is covered. The opening 105a of the cover plate 105 exposes the non-coating area 103a, and a coating layer 107 is applied to the exposed non-coating area 103a.

[0046] in Figure 6 for Figure 5 An enlarged view of one of the carrier strips 101 corresponding to one of the limiting grooves 104a; Figure 7 for Figure 6 Structural view after the coating layer has been applied.

[0047] In this embodiment, please refer to Figure 3 The cover plate 105 and the tray 104 are connected by magnetic adsorption. The magnetic adsorption connection makes the connection and disassembly between the cover plate 105 and the tray 104 faster and more convenient, without the need for tools, thus improving operating efficiency. It also facilitates the quick assembly and disassembly of the clamps, making cleaning and maintenance easier.

[0048] In this embodiment, the cover plate 105 is made of magnetic material, and the tray 104 is fixed with a number of magnet blocks 106, which ensures the stability and reliability of the magnetic adsorption connection. Even under adverse conditions such as vibration, it can ensure that the cover plate 105 and the tray 104 are tightly attached, preventing problems such as inaccurate exposure of the non-coated area 103a due to the loosening of the cover plate 105.

[0049] In some embodiments, the cover plate 105 and the tray 104 are fixedly connected by screws. This connection method is more secure than magnetic adsorption connection and is suitable for occasions where the stability of the clamp assembly 108 is required. It can effectively prevent product damage or process failure caused by the loosening of the clamp assembly 108 during the dispensing process, thereby improving the reliability of the process and the quality of the product.

[0050] In this embodiment, please refer to Figure 3 The tray 104 also has several hand slots 104b, which are connected to the corresponding limiting slots 104a. The design of the hand slots 104b on the tray 104 makes it convenient for operators to use their hands to hold the slots and easily remove or put the carrier strip 101 from the tray 104, which improves the convenience and efficiency of operation and reduces the risk of product damage caused by inconvenient operation.

[0051] In this embodiment, please refer to Figure 3 The tray 104 has a plurality of alignment protrusions 104c; the cover plate 105 has a plurality of alignment holes 105b corresponding to the alignment protrusions 104c; the cooperative design of the alignment protrusions 104c and the alignment holes 105b ensures that the cover plate 105 and the tray 104 can be quickly and accurately aligned during assembly, which improves the assembly accuracy and efficiency, avoids problems such as incomplete or incorrect exposure of the non-coated area 103a due to inaccurate alignment, and ensures the smooth progress of subsequent processes.

[0052] In this embodiment, please refer to Figure 1 The shape of the loading groove 102 is matched with the shape of the part to be coated 103, so that the part to be coated 103 can be more stably loaded on the carrier strip 101, reducing process defects caused by the shaking of the part to be coated 103 during the coating or dispensing process, improving the processing accuracy and quality of the part to be coated 103, and also improving the loading efficiency of the carrier strip 101.

[0053] In this embodiment, please refer to Figure 3The shape of the limiting groove 104a is matched with the shape of the carrier strip 101, which ensures the stable placement of the carrier strip 101 in the tray 104 and prevents the carrier strip 101 from sliding or shifting in the tray 104. This further improves the overall stability of the clamp assembly 108, provides more reliable support for the subsequent dispensing process, and ensures the smooth progress of the process.

[0054] In this embodiment, please refer to Figure 3 The opening 105a is a continuous opening 105a along the extension direction of the cover plate 105.

[0055] In other embodiments, please refer to Figure 10 The opening 105a is composed of a plurality of sub-openings 105c along the extension direction of the cover plate 105, and the sub-openings 105c expose the non-coating area 103a. The cover plate 105 between adjacent sub-openings 105c can also fix the part to be coated 103, thereby enabling the use of smaller parts to be coated 103.

[0056] Whether it is a continuous opening 105a or multiple sub-openings 105c, it can be adjusted according to the shape and position of the non-coating area 103a of the workpiece to be coated 103, so as to better meet the process requirements of different workpieces to be coated 103, improve the versatility and adaptability of the fixture assembly 108, and also provide more options for the precise exposure of the non-coating area 103a.

[0057] Accordingly, please refer to Figure 8 and Figure 9 The present invention also provides a coating fixture, including a carrier assembly 200 formed by the carrier clamp 100 described above. The carrier assembly 200 includes a carrier 101, the carrier 101 having a plurality of loading grooves 102 arranged along its extension direction. The loading grooves 102 are used to load a workpiece 103 to be coated. The surface of the workpiece 103 to be coated has a non-coating area 103a. A cover layer 107 is coated on the non-coating area 103a.

[0058] In this embodiment, the carrier strip 101 and the clamping assembly 108 are used to achieve the process of applying a coating layer 107 to multiple parts 103 to be coated on the entire carrier strip 101 at one time. After that, the entire carrier strip 101 coated with the coating layer 107 is taken out from the clamping assembly 108 and used as the carrier strip assembly 200.

[0059] In this embodiment, not only is the stable mounting of the small part to be coated 103 and the effective protection of the non-coating area 103a achieved, but the protective effect of the non-coating area 103a is further enhanced by the covering layer 107, which improves the quality of subsequent coating, reduces the product scrap rate caused by the miscoating of the non-coating area 103a, and improves production efficiency and economic benefits.

[0060] In this embodiment, the cover layer 107 includes a dispensing layer. This dispensing layer, as a commonly used cover layer material, forms a physical barrier through the colloid, preventing the coating material from depositing into the non-coating area 103a, thus avoiding any impact on product performance or appearance. Simultaneously, the dispensing process is relatively simple, low-cost, easy to operate and control, and suitable for large-scale production, further improving the practicality and economy of the coating fixture.

[0061] In this embodiment, please refer to Figure 8 and Figure 9 It also includes a coating frame 201, which has a slot 202 for the carrier assembly 200. The slot 202 is used to fix the carrier assembly 200. The coating frame 201 provides additional fixation and support for the carrier assembly 200, making the carrier assembly 200 more stable during the coating process and reducing the risk of uneven coating or failure caused by displacement of the carrier assembly 200. At the same time, the design of the slot 202 of the coating frame 201 also facilitates the quick positioning and installation of the carrier assembly 200, improving the efficiency and reliability of the coating process.

[0062] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
