[0002] Plastic is an excellent insulating material, and various thin-walled plastic parts are frequently found in semiconductor devices. These parts effectively prevent current leakage and short circuits, ensuring the safe operation of electrical equipment and facilitating compact structural design. However, thin-walled plastics often encounter processing problems such as deformation, chipping, and breakage, leading to increased manufacturing difficulty and costs, and impacting scheduled delivery times. Utility Model Content

[0003] In view of the problems of deformation, chipping, and breakage that occur during the processing of thin-walled plastics in the prior art, this utility model provides a freezing suction cup suitable for thin-walled plastic workpieces.

[0004] This utility model discloses a freezing suction cup suitable for thin-walled plastic workpieces, comprising a suction cup base plate and a support plate. The support plate is detachably fixed to the suction cup base plate. A cold water inlet is provided on one side wall of the suction cup base plate, and a cold water outlet is provided on the other side wall of the suction cup base plate. A support plate inlet is provided on the end face of the suction cup base plate near the support plate, and a support plate outlet is provided on the end face of the suction cup base plate near the support plate, near the cold water outlet. A water inlet channel is provided between the cold water inlet and the support plate inlet, and a water outlet channel is provided between the support plate outlet and the cold water outlet. A plurality of freezing stations are sequentially arranged on the end face of the support plate away from the suction cup base plate, from the cold water inlet to the cold water outlet. A freezing trough is provided on the end face of the support plate near the suction cup base plate, corresponding to the plurality of freezing stations. One end of the freezing trough is connected to the support plate inlet, and the other end of the freezing trough is connected to the support plate outlet.

[0005] Preferably, the plurality of freezing stations include at least one first freezing station and at least one second freezing station. The at least one first freezing station is located on the side of the at least one second freezing station near the cold water inlet. The freezing tank includes a first freezing tank and a second freezing tank. The first freezing tank is located on the end face of the support plate near the suction cup bottom plate, corresponding to the at least one first freezing station. The second freezing tank is located on the end face of the support plate near the suction cup bottom plate, corresponding to the at least one second freezing station. The first freezing tank and the second freezing tank are connected. The water inlet of the support plate is connected to the first freezing tank, and the water outlet of the support plate is connected to the second freezing tank.

[0006] Furthermore, the vertical depth of at least one first freezing station is less than the vertical depth of at least one second freezing station.

[0007] Furthermore, the distance from the bottom surface of the first freezing tank to each first freezing station is equal to the distance from the bottom surface of the second freezing tank to each second freezing station; each second freezing station has a side groove on its outer periphery, and the side groove is connected to its corresponding second freezing station; when the number of at least one first freezing station is greater than 1, a connecting groove is provided between two adjacent first freezing stations, and the two adjacent first freezing stations are connected through the connecting groove located between them.

[0010] Compared with existing technologies, this utility model provides a freezing suction cup suitable for thin-walled plastic workpieces. By setting a cold water inlet, a water inlet channel, a carrier plate inlet, a carrier plate outlet, an outlet channel, and a cold water outlet on the suction cup base plate, and by setting a freezing groove on the end face of the carrier plate near the suction cup base plate, communicating with the carrier plate inlet and outlet, a freezing path is easily formed. The cold water within the freezing path cools the carrier plate, and the water that seeps into the workpiece's gaps on the end face of the carrier plate away from the suction cup base plate freezes into ice, fixing the workpiece in place. This also ensures seamless contact with the thin-walled side, minimizing vibration during processing and preventing workpiece deformation, chipping, and breakage. By detachably fixing the carrier plate to the suction cup base plate, after processing one product, only the carrier plate needs to be replaced to process other products, making it suitable for small-batch, multi-variety processing and reducing manufacturing costs.

[0021] Please refer to the above. Figures 1 to 3 The present invention provides a freezing suction cup suitable for thin-walled plastic workpieces, comprising a suction cup base plate 10 and a support plate 20. The support plate 20 is detachably fixed on the suction cup base plate 10 so as to replace the support plate 20 as needed to meet the processing of various workpieces.

[0022] A cold water inlet 11 is provided on one side wall of the suction cup base plate 10, and a cold water outlet 12 is provided on the other side wall of the suction cup base plate 10. A carrier plate inlet 13 is provided on the end face of the suction cup base plate 10 near the cold water inlet 11, and a carrier plate outlet 14 is provided on the end face of the suction cup base plate 10 near the cold water outlet 12. A water inlet channel 15 is provided between the cold water inlet 11 and the carrier plate inlet 13, and a water outlet channel 16 is provided between the carrier plate outlet 14 and the cold water outlet 12.

[0023] On the end face of the bearing plate 20 away from the suction cup base plate 10, a number of freezing stations 201 are arranged sequentially from the cold water inlet 11 to the cold water outlet 12. On the end face of the bearing plate 20 near the suction cup base plate 10, a freezing tank 202 is provided at a position corresponding to the number of freezing stations 201. One end of the freezing tank 202 is connected to the bearing plate inlet 13, and the other end of the freezing tank 202 is connected to the bearing plate outlet 14, so as to form a freezing path of cold water inlet 11 → water inlet channel 15 → bearing plate inlet 13 → freezing tank 202 → bearing plate outlet 14 → water outlet channel 16 → cold water outlet 12. The workpieces in the number of freezing stations 201 are frozen and fixed in sequence. The water that seeps into the gaps of the workpiece at each station is frozen into ice to fix the workpiece, thereby minimizing the vibration generated during processing and avoiding the occurrence of workpiece deformation, chipping, and breakage.

[0024] When thin-walled plastic workpieces require two processing steps, please refer to [link to relevant documentation]. Figures 1 to 5 The plurality of freezing stations 201 include at least one first freezing station 21 and at least one second freezing station 22. The at least one first freezing station 21 is located on the side of the at least one second freezing station 22 near the cold water inlet 11. The freezing tank 202 includes a first freezing tank 23 and a second freezing tank 24. The first freezing tank 23 is located on the end face of the support plate 20 near the suction cup base plate 10, corresponding to the at least one first freezing station 21. The second freezing tank 24 is located on the end face of the support plate 20 near the suction cup base plate 10, corresponding to the at least one second freezing station 22. At the corresponding positions, the first freezing tank 23 and the second freezing tank 24 are connected, the water inlet 13 of the bearing plate is connected to the first freezing tank 23, and the water outlet 14 of the bearing plate is connected to the second freezing tank 24, so as to form a freezing path of cold water inlet 11 → water inlet channel 15 → water inlet 13 of the bearing plate → first freezing tank 23 → second freezing tank 24 → water outlet 14 of the bearing plate → water outlet channel 16 → cold water outlet 12. First, the workpieces in at least one first freezing station 21 are frozen and fixed in sequence, and then the workpieces in at least one second freezing station 22 are frozen and fixed in sequence.

[0025] To ensure the effectiveness of the freeze-fixation process at each step, please refer to [link / reference needed]. Figure 3At least one first freezing station 21 has a vertical depth less than at least one second freezing station 22. Preliminary machining of the thin-walled plastic workpiece blank is performed at the first freezing station 21, and fine machining of the thin-walled plastic workpiece is performed at the second freezing station 22. This facilitates better freezing and fixing of the thin-walled plastic workpiece requiring fine machining, ensuring machining accuracy and quality. Furthermore, to achieve seamless contact between the sidewalls of the thin-walled plastic workpiece requiring fine machining and to reduce vibration during machining, please refer to [link to relevant documentation]. Figure 1 , Figure 2 or Figure 4 Each second freezing station 22 has a side groove 221 on its outer periphery, and the side groove 221 communicates with its corresponding second freezing station 22. In actual use, the structure of the side groove 221 can be set according to the actual workpiece processing needs, for example... Figure 1 As shown, since the middle part of the workpiece sidewall does not need to be machined, the side groove 221 consists of two non-connected machining grooves.

[0026] In order to make the freezing effect of the cold water in the freezing path on the water in the first freezing station 21 and the second freezing station 22 basically the same, the distance from the bottom surface of the first freezing tank 23 to each first freezing station 21 is equal to the distance from the bottom surface of the second freezing tank 24 to each second freezing station 22.

[0027] To ensure the effective freezing and fixing of the workpieces within the first freezing station 21, please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 or Figure 4 When the number of at least one first freezing station 21 is greater than 1, a connecting groove 211 is provided between two adjacent first freezing stations 21. The two adjacent first freezing stations 21 are connected by the connecting groove 211 between them, so that the workpieces in the two adjacent first freezing stations 21 can be frozen together by water.

[0028] To reduce cold loss and significantly shorten the freezing process time, please refer to [reference needed]. Figure 3 , Figure 6 and Figure 7 The freezing suction cup also includes an insulating cotton pad 30. The insulating cotton pad 30 has a first groove 31 in the middle of one end and a second groove 32 in the middle of the other end. The suction cup base plate 10 has a receiving groove 17 in the middle of the end face away from the bearing plate 20, which cooperates with the insulating cotton pad 20. The insulating cotton pad 30 is placed in the receiving groove 17. The water inlet channel 15 is located between the first grooves 31 and the water outlet channel 16 is located between the second grooves 32.

[0029] Furthermore, in order to ensure the fixation effect of the thermal insulation pad 30 in the receiving groove 17, a plurality of fixing posts 171 are provided in the receiving groove 17, and fixing holes 33 are provided on the thermal insulation pad 30 at positions corresponding to the plurality of fixing posts 171, and the plurality of fixing posts 171 are inserted into their corresponding fixing holes 33.

[0030] To prevent cold water leakage, please refer to Figure 3 and Figure 5 The freezing suction cup also includes a sealing ring 40. A sealing groove 25 is provided on the end face of the bearing plate 20 near the suction cup base plate 10. The sealing groove 25 is located on the outer periphery of the first freezing groove 23 and the second freezing groove 24. The sealing ring 40 is disposed in the sealing groove 25.

[0031] In practical use, the suction cup base plate 10 is a standard base plate that can be precisely positioned and fixed on the four-axis bridge plate, enabling multi-angle processing. The cold water in the chiller's water tank is pumped into the suction cup base plate 10 by a centrifugal pump, and then flows back into the chiller's water tank via the suction cup base plate 10. During the processing of thin-walled plastic workpieces, the chiller needs to continuously cool the water in the water tank.

[0032] Usage process: First, a through hole is machined at an appropriate position on the thin-walled plastic workpiece blank (without damaging the workpiece features), and a stepped groove is machined on one end surface of the workpiece using a conventional milling machine to effectively improve the freezing firmness, allowing for a greater depth of cut and machine tool feed rate during part machining, thereby improving machining efficiency; then, the surface of the workpiece blank with the stepped groove is placed in the first freezing station 21 of the support plate 20, and water is filled into the through hole. The cold water in the freezing path is used to cool the support plate 20, and the water that seeps into the gaps of the workpiece freezes into ice to fix the workpiece, completing the initial machining of the workpiece; after that, the initially machined workpiece is placed in the second freezing station 22 of the support plate 20, and the cold water in the freezing path is used to cool the support plate 20, and the water that seeps into the gaps of the workpiece freezes into ice to fix the workpiece, completing the fine machining of the workpiece and obtaining the machined workpiece.

[0033] After the workpiece is processed, the carrier plate 20 is removed from the suction cup base plate 10, and the carrier plate 20 of another workpiece is installed to process the other workpiece.

[0034] This invention relates to a freezing suction cup suitable for thin-walled plastic workpieces. The suction cup base plate is equipped with a cold water inlet, a water inlet channel, a carrier plate inlet, a carrier plate outlet, an outlet channel, and a cold water outlet. A freezing groove, connected to the carrier plate inlet and outlet, is located on the end face of the carrier plate near the suction cup base plate, facilitating the formation of a freezing path. Cold water within this path cools the carrier plate, and water seeping into the workpiece's gaps on the end face of the carrier plate away from the suction cup base plate freezes into ice, securing the workpiece. This provides seamless contact with the thin-walled side, minimizing vibration during processing and preventing workpiece deformation, chipping, and breakage. By detachably fixing the carrier plate to the suction cup base plate, after processing one product, only the carrier plate needs to be replaced to process other products, making it suitable for small-batch, multi-variety processing and reducing manufacturing costs.

[0035] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described above can be combined with each other as long as they do not conflict with each other. It must be pointed out that the disclosed embodiments do not limit the scope of this utility model. On the contrary, any modifications and refinements made without departing from the spirit and scope of this utility model are within the patent protection scope of this utility model.
