Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment, and more specifically, it relates to an automatic opening and clamping cleaning device for TRAY trays. Background Technology

[0002] Because semiconductor packaging substrates have intricate circuitry, each process requires a tray to separate the substrate for automated transport. To prevent contamination of the substrate during tray separation, the trays need to be cleaned. Currently, commonly used equipment includes horizontal chain conveyor belt systems and traditional vertical cleaning systems. However, horizontal chain conveyor belt systems cannot automatically open the clamps holding the substrate on the trays, resulting in incomplete cleaning or drying of the tray clamps. While traditional vertical cleaning systems can overcome the inability to open the clamps by installing auxiliary mechanisms (such as cylinders), their structure is relatively complex. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model aims to provide an automatic cleaning device for TRAY trays, which opens the fixing clips during the cleaning and drying process of TRAY trays through a simple structure.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] An automatic clamping and cleaning device for TRAY trays includes a frame, within which a washing tank and a drying tank are formed. A washing mechanism is installed in the washing tank, and a drying mechanism is installed in the drying tank. A conveying mechanism passes through both the washing tank and the drying tank. The conveying mechanism drives the TRAY trays to sequentially pass through the washing tank and the drying tank. During this process, the washing mechanism cleans the TRAY trays, and the drying mechanism dries them. At least one set of gravity-type clamping roller mechanisms is installed in both the washing tank and the drying tank to open the clamps on the TRAY trays. These gravity-type clamping roller mechanisms are connected to the conveying mechanism, which drives them to rotate.

[0006] Furthermore, each of the aforementioned self-weight opening and closing roller mechanisms includes a rotating shaft, with an opening and closing roller respectively provided at both ends of the rotating shaft, and a first gear provided at one end of the rotating shaft.

[0007] Furthermore, at least one limiting sleeve is also fitted onto the rotating shaft.

[0008] Furthermore, the conveying mechanism includes a double-layer roller conveyor and a gear module, wherein the double-layer roller conveyor is connected to the gear module.

[0009] Furthermore, the gear module includes a second gear, a third gear, and a fourth gear, all sleeved on each group of rollers in the lower layer of the double-layer roller line. The fourth gear is meshed with one of the third gears. Each group of second gears is meshed with a fifth gear. The fifth gears are all sleeved on a connecting rod, which is rotatably inserted into several sets of support seats.

[0010] Furthermore, the lower roller of the double-layer roller is provided with limit wheels; the upper roller of the double-layer roller is provided with closed rollers.

[0011] Furthermore, the cleaning mechanism includes an upper spray pipe, a lower spray pipe, and a clamp cleaning spray pipe; the upper spray pipe, the lower spray pipe, and the clamp cleaning spray pipe are connected to a spray pump via a liquid delivery pipe.

[0012] Furthermore, nozzles are respectively installed on the upper spray pipe, the lower spray pipe, and the clamp cleaning spray pipe.

[0013] Furthermore, the drying mechanism includes an upper air duct, a lower air duct, and a clamp drying air duct; the upper air duct, the lower air duct, and the clamp drying air duct are connected to a blower via an air supply pipe.

[0014] Furthermore, air knives are installed on the upper air duct and the lower air duct respectively, and air nozzles are installed on the clamp drying air duct.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a self-weight opening roller mechanism, enables the fixed clamps on the TRAY tray to automatically open when it passes through the washing tank and drying tank, ensuring that the inside and surrounding areas of the clamp are fully cleaned and dried, thus solving the problem of difficult cleaning and drying of the clamps in traditional equipment; and the self-weight opening roller mechanism uses the driving force of the conveying mechanism to rotate, which avoids scratching the TRAY tray during movement, while eliminating the need for an additional driving device, reducing the complexity and cost of the equipment, and improving the operating efficiency and stability of the equipment;

[0017] 2. The roller line of this utility model adopts a double-layer roller line. By adjusting the spacing of the double-layer roller line, it can meet the needs of TRAY trays of different thicknesses, thereby improving the applicability. At the same time, the spray pipes of the cleaning mechanism and the air ducts of the drying mechanism are arranged vertically on both sides of the double-layer roller line, which achieves full coverage of the TRAY tray and its fixing clips, ensuring the cleaning effect and rapid drying of the TRAY tray and its fixing clips, and avoiding moisture residue.

A cleaning mechanism 2 is installed in the washing tank 11, and a drying mechanism 3 is installed in the drying tank 12. A conveying mechanism 4 passes through the washing tank 11 and the drying tank 12. The conveying mechanism 4 drives the TRAY trays to sequentially pass through the washing tank 11 and the drying tank 12. During this process, the washing mechanism 2 cleans the TRAY trays, and the drying mechanism 3 dries them. The tray is dried. The washing tank 11 and the drying tank 12 are respectively provided with two sets of self-weight opening roller mechanisms 5 that can open the fixing clips on the TRAY tray. The self-weight opening roller mechanism 5 is connected to the conveying mechanism 4. The conveying mechanism 4 can drive the self-weight opening roller mechanism 5 to rotate. Of course, the number of sets of self-weight opening roller mechanisms 5 provided in the washing tank 11 and the drying tank 12 is only one embodiment and is not intended to limit the scope of this application. In actual settings, the specific number of sets can be set according to actual needs.

[0033] Further, see Figure 2 As shown, in this embodiment, the conveying mechanism 4 includes a double-layer roller conveyor 41 and a gear module 42, wherein the double-layer roller conveyor 41 is connected to the gear module 42; wherein, see Figure 3As shown, in this embodiment, the gear module 42 includes a second gear 421, a third gear 422 sleeved on each group of rollers in the lower layer of the double-layer roller conveyor 41, and a fourth gear 423 sleeved on each group of rollers in the upper layer of the double-layer roller conveyor 41.

Each fifth gear 424 is sleeved on a connecting rod 425, and the connecting rod 425 is rotatably inserted into several sets of support seats 426. During installation, the support seats 426... After the connecting rod 425 is fixed on the double-layer roller conveyor 41, one end of the connecting rod 425 is connected to a drive motor (not shown in the figure). During operation, the drive motor drives the connecting rod 425 to rotate, thereby driving the fifth gear 424 to rotate. Through the fifth gear 424, the second gear 421, the third gear 422 and the fourth gear 423, the rollers in the upper and lower layers of the double-layer roller conveyor 41 are driven to rotate synchronously in opposite directions, thereby driving the TRAY disc to pass through the washing tank 11 and the drying tank 12 in sequence.

[0034] See also Figure 3 As shown, in this embodiment, the lower roller of the double-layer roller conveyor 41 is provided with limiting wheels 43, which limit the TRAY tray during the conveying process and prevent it from deviating; the upper roller of the double-layer roller conveyor 41 is provided with closing rollers 44, which assist the fixing clamps on the TRAY tray to close.

[0035] Further, see Figure 5 As shown, in this embodiment, the cleaning mechanism 2 includes an upper spray pipe 21, a lower spray pipe 22, and a clamp cleaning spray pipe 23; the upper spray pipe 21, the lower spray pipe 22, and the clamp cleaning spray pipe 23 are connected to a spray pump 25 via a liquid delivery pipe 24; during installation, refer to... Figure 1 and Figure 7 As shown, the upper spray pipe 21, the lower spray pipe 22, and the clamp cleaning spray pipe 23 are all disposed in the water washing tank 11. The upper spray pipe 21 and the clamp cleaning spray pipe 23 are located above the conveying mechanism 4, and the lower spray pipe 22 is located below the conveying mechanism 4. The spray pump 25 is disposed on the frame 1, and the suction port of the spray pump 25 is submerged in the cavity of the frame 1 for holding the spray liquid. In this embodiment, nozzles 26 are respectively installed on the upper spray pipe 21, the lower spray pipe 22, and the clamp cleaning spray pipe 23. (Continue to refer to...) Figure 5As shown, each of the upper spray pipe 21 and the lower spray pipe 22 is provided with a nozzle 26 at intervals, and the nozzles 26 are all facing the conveying mechanism 4; while the clamp cleaning spray pipe 23 is provided with a pair of nozzles 26 at intervals, and the nozzles 26 are all inclined downwards on the bottom surface of the clamp cleaning spray pipe 23; during cleaning, the TRAY disc body is cleaned by the nozzles 26 provided on the upper spray pipe 21 and the lower spray pipe 22, and the fixing clamps on both sides of the TRAY disc are cleaned by the nozzles 26 provided on the clamp cleaning spray pipe 23.

[0036] Further, see Figure 6 As shown, in this embodiment, the drying mechanism 3 includes an upper air duct 31, a lower air duct 32, and a clamp-type drying air duct 33; the upper air duct 31, the lower air duct 32, and the clamp-type drying air duct 33 are connected to a blower 35 via an air supply duct 34; during installation, refer to... Figure 1 and Figure 7 As shown, the upper air duct 31, the lower air duct 32, and the clamp drying air duct 33 are all arranged in the drying tank 12. The upper air duct 31 and the clamp drying air duct 33 are arranged above the conveying mechanism 4, the lower air duct 32 is arranged below the conveying mechanism 4, and the blower 35 is arranged on the frame 1. In this embodiment, see further... Figure 6 As shown, air knives 36 facing the conveying mechanism 4 are respectively installed on the upper air duct 31 and the lower air duct 32, and a pair of inclined air nozzles 37 are installed at intervals on the bottom surface of the clamp drying air duct 33; during drying, the TRAY tray body is dried by the air knives 36, and the fixed clamps on both sides of the TRAY tray are dried by the air nozzles 37.

[0037] Further, see Figure 4As shown, in this embodiment, each set of self-weight opening and closing roller mechanisms 5 includes a rotating shaft 51, with an opening and closing roller 52 respectively provided at both ends of the rotating shaft 51, and a first gear 53 provided at one end of the rotating shaft 51. During installation, the rotating shaft 51 is rotatably and vertically mounted on the double-layer roller conveyor 41, and the rotating shaft 51 is located on the upper layer of the double-layer roller conveyor 41 and distributed between the rollers. At this time, the opening and closing roller 52 is located inside the washing tank 11 or the drying tank 12, while the first gear 53 is located outside the washing tank 11 or the drying tank 12, and the first gear 53 is located on the side of the gear module 42. The first gear 53 is meshed with a third gear 422. During operation, the first gear 53 is engaged with the third gear. Driven by 422, the rotating shaft 51 and the opening and closing roller 52 mounted on the rotating shaft 51 rotate synchronously with the upper roller of the double-layer roller conveyor 41. The rotating opening and closing roller 52 can effectively prevent scratches on the moving TRAY disc. In order to prevent the rotating shaft 51 from moving along its axial direction in the washing tank 11 or the drying tank 12 and causing the position of the opening and closing roller 52 to change, a limiting sleeve 54 is also sleeved on the rotating shaft 51 at the end side of the first gear 53. The limiting sleeve 54 is located between the first gear 53 and the opening and closing roller 52 and is disposed in the washing tank 11 or the drying tank 12. Through the cooperation of the limiting sleeve 54 and the first gear 53, the rotating shaft 51 is prevented from moving along its axial direction.

[0038] The working principle of this utility model is as follows:

[0039] See Figure 7-9 As shown (label B in the figure represents the TRAY tray, and label C in the figure represents this equipment), when it is necessary to clean the TRAY tray, the TRAY tray is first placed on the conveyor mechanism 4 in sequence. At this time, the TRAY tray is located between the double-layer roller line 21 and is restricted between the limit wheels 43. The TRAY tray is conveyed forward by the conveyor mechanism 4 and passes through the washing tank 11 and the drying tank 12 in sequence to complete the cleaning operation of the TRAY tray.

[0040] During the transport of the TRAY disc in the washing tank 11, the upper spray pipe 21 and the lower spray pipe 22 spray the TRAY disc through the nozzle 26 to clean it. When the fixed clamp in the TRAY disc moves to the opening and closing roller 52, the opening and closing roller 52 presses down on the rear end of the fixed clamp to open it. After the fixed clamp is opened, it moves to the clamp cleaning spray pipe 23, which cleans the fixed clamp through the nozzle 26. After cleaning, it moves to the closing roller 24, where the fixed clamp in the TRAY disc is closed with the assistance of the closing roller 24.

[0041] After the TRAY tray is cleaned in the washing tank 11, it is conveyed to the drying tank 12 by the conveying mechanism 4. The upper air pipe 31 and the lower air pipe 32 blow air onto the TRAY tray through the air knife 36 set on them to dry the TRAY tray body. When the fixed clamp in the TRAY tray runs to the opening and closing roller 52, the opening and closing roller 52 presses down on the rear end of the fixed clamp to open the fixed clamp. After the fixed clamp is opened, when it runs to the clamp drying air pipe 33, the clamp drying air pipe 33 blows air onto the fixed clamp through the air nozzle 37 set on it to dry the fixed clamp. After drying, it runs to the closing clamp rotating wheel 24, where the fixed clamp in the TRAY tray closes with the help of the closing clamp rotating wheel 24.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
