Description

Technical Field

[0001] This application belongs to the technical field of glass hot bending equipment, specifically relating to a mold conveying assembly for hot bending equipment and hot bending equipment. Background Technology

[0002] Hot bending equipment is a key processing and forming device for producing curved glass. In the conventional production process, the glass sheet is first placed in a mold, and then a pushing mechanism pushes the mold into the furnace body of the equipment. The mold is then moved between multiple stations on the processing platform, allowing the glass sheet to undergo preheating, forming, pressure holding, and cooling processes in sequence. This mold pushing method has high transfer accuracy and a high yield rate when applied to the processing of small molds and glass products. However, when applied to medium and large molds, the weight and volume of the mold are large, and the friction and friction area between the mold and the processing platform increase. Consequently, wear occurs during movement, generating a large amount of dust. Dust accumulation inside the furnace not only reduces the cleanliness of the furnace cavity but also contaminates the glass products, leading to a decrease in the yield rate. Utility Model Content

[0010] In some embodiments, there are two rotary drive mechanisms and two transmission shafts, which are arranged laterally in parallel intervals.

[0012] In some embodiments, both the first support arm group and the second support arm group include at least one positioning support arm, the top of which is provided with an arm positioning structure that can form an interlocking connection with the bottom of the mold.

[0013] In some embodiments, there are multiple first support arm groups and multiple second support arm groups, and the multiple first support arm groups and multiple second support arm groups are arranged sequentially at intervals along the axial direction of the corresponding transmission shaft.

[0014] In some embodiments, the mold conveying assembly further includes a rotating shaft connecting seat, the rotary drive mechanism and the transmission shaft are both disposed on the rotating shaft connecting seat, the transfer drive mechanism includes a guide rail extending laterally and a slide table forming a sliding engagement with the guide rail, and the rotating shaft connecting seat is fixedly connected to the slide table.

[0041] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0042] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0043] like Figure 1 As shown, a first exemplary embodiment of this application provides a mold conveying assembly for a hot bending equipment. The mold conveying assembly includes multiple processing stations 1, a mold support structure 2, a mold lifting mechanism 3, and a transfer drive mechanism 4. Referring to… Figure 1Multiple processing stations 1 can be arranged sequentially in the transverse direction on the processing platform of the hot bending equipment. The mold support structure 2 can switch between a support position for supporting mold A and a clearance position where it is out of contact with the mold. The mold lifting mechanism 3 is used to lift the mold A located at the processing station 1 and lower the lifted mold A onto the mold support structure 2 in the support position. The transfer drive mechanism 4 can drive the mold support structure 2 to move between the multiple processing stations 1. In other words, it can drive the mold A to move between the multiple processing stations 1. Specifically, it can move between two adjacent processing stations 1 or between any two non-adjacent processing stations 1. This application does not limit this.

[0044] Therefore, when using the mold conveying assembly of this exemplary embodiment to transfer the mold A loaded with glass to another workstation, the mold lifting mechanism 3 first lifts the mold A located at the processing station 1, causing the mold A to detach from the processing platform. Then, the mold support structure 2, which was in a clearance position, is adjusted to a support position. Next, the mold lifting mechanism 3 is used to place the lifted mold A onto the mold support structure 2. Then, the transfer drive mechanism 4 drives the mold support structure 2 to move the mold A to the next processing station 1. At this time, the mold lifting mechanism 3 can be used again to lift the mold A located on the mold support structure 2. Then, the mold support structure 2, which was in a support position, is adjusted to a clearance position to avoid blocking the descent of the mold A. Finally, the mold lifting mechanism 3 places the lifted mold A onto the platform of the next processing station 1, so that the mold A does not need to contact the processing platform during the transfer process, avoiding dust generation due to friction and wear of the mold A, improving the cleanliness of the production line environment, thereby preventing the glass products in the mold A from being contaminated by dust and improving the yield of glass products.

[0045] This application does not limit the specific structure and position adjustment method of the mold support structure 2. The specific structure can be in the form of support arm, support plate, support net, etc. The movement method can be translation, rotation or a combination of both, depending on whether the specific structure of the mold support structure 2 is applicable and the actual setting of the support position and the avoidance position.

[0046] Taking rotational adjustment as an example, refer to Figure 3The mold conveying assembly also includes a rotary drive mechanism 5 and a transmission shaft 6. The transmission shaft 6 extends along the arrangement direction of the plurality of processing stations 1. The mold support structure 2 is mounted on the transmission shaft 6. In this case, the rotary drive mechanism 5 can drive the transmission shaft 6 to rotate circumferentially, thereby switching the mold support structure 2 between a support position and a clearance position. Compared with translational adjustment, using rotary adjustment of the mold support structure 2 allows for a more compact layout of the adjustment mechanism, saving space and making it more suitable for production conditions involving long-distance, multi-station mold conveying. It is understood that in this embodiment, the support position and the clearance position are located at different positions along the rotation path of the mold support structure 2.

[0047] To ensure that the clearance position of the mold support structure 2 is far away from the support position and to avoid interference with the downward displacement of the mold A, the position of the mold support structure 2 can be adjusted by combining translation and rotation. For example, a translation mechanism can be added on the basis of the above embodiment to drive the transmission shaft 6 to move laterally, thereby moving the mold support structure 2 away from or closer to the multiple processing stations 1. This application does not limit this, as long as the supporting function of the mold support structure 2 can be realized and its displacement requirements can be met.

[0048] The transmission shaft 6 can be one or two. To ensure better support stability of the mold support structure 2, preferably, two transmission shafts 6 are provided, as shown in the reference. Figures 1 to 3 Two drive shafts 6 can be distributed on both sides of multiple processing stations 1. The mold support structure 2 includes a first support structure and a second support structure respectively mounted on the two drive shafts 6. When in the support position, the first support structure and the second support structure can provide multi-point support for the mold A to improve the stability of the mold A. Correspondingly, two rotary drive mechanisms 5 are also provided, and the two rotary drive mechanisms 5 drive and connect the two drive shafts 6 respectively. Of course, provided that the mold support structure 2 can provide stable support for the mold A, a single drive shaft 6 can also be provided to drive the mold support structure 2 to adjust its position; this application does not limit this.

[0049] Furthermore, when using a support arm as the mold support structure 2, such as Figure 3As shown, the first support structure is formed as a first support arm group 201, and the second support structure is formed as a second support arm group 202. Both the first support arm group 201 and the second support arm group 202 include multiple support arms 203 arranged sequentially at intervals along the axial direction of the transmission shaft 6. When the first support arm group 201 and the second support arm group 202 are driven to rotate for adjustment, the two rotary drive mechanisms 5 can operate in opposite directions to drive the corresponding transmission shaft 6 to rotate relative to each other, thereby causing the first support arm group 201 and the second support arm group 202 to swing relative to each other. For example, when switching from the avoidance position to the support position, the first support arm group 201 and the second support arm group 202 swing towards a position closer to each other; when switching from the support position to the avoidance position, the first support arm group 201 and the second support arm group 202 swing towards a position further apart from each other, thus realizing the switching between the support position and the avoidance position.

[0050] In this exemplary embodiment, as Figure 3 As shown, the rotary drive mechanism 5 may include a rotary motor, a reducer, and a coupling. The output shaft of the rotary motor can be coaxially connected to the transmission shaft 6 via the reducer and coupling. When the mold conveying assembly of this embodiment is applied to a hot bending equipment, such as... Figures 1 to 3 As shown, the drive shaft 6 can pass through the side plate of the furnace body of the hot bending equipment. A guide sleeve can be provided between the drive shaft 6 and the side plate of the furnace body, and the drive shaft 6 can be movably inserted into the guide sleeve. The guide sleeve can at least serve the functions of guiding and lubrication, so that the drive shaft 6 can rotate smoothly. Considering that the drive shaft 6 is relatively long, in order to improve the stability of the drive shaft 6, such as... Figure 3 As shown, a support member for supporting the shaft body can be provided at the middle section of the transmission shaft 6. For example, the support member can be a support sleeve that is sleeved on the transmission shaft 6. Multiple support sleeves can be provided, and multiple support sleeves are arranged sequentially at intervals along the axial direction of the transmission shaft 6, so as to realize multi-point support for the transmission shaft 6, so as to prevent the transmission shaft 6 from deforming due to gravity and avoid jamming during rotation or movement.

[0051] In an optional or preferred embodiment, such as Figure 3 and Figure 4 As shown, multiple support arms 203 are all perpendicular to their corresponding transmission shafts 6. Specifically, the support arms 203 can be mounted on the transmission shafts 6 via arm mounting seats, wherein the arm mounting seats can be locked onto the transmission shafts 6 via clamping blocks and positioning pins. Thus, in the supported position, the multiple support arms 203 are parallel to the horizontal plane, i.e., in a horizontal state, and the top surfaces of the multiple support arms 203 together form a support surface for placing the mold A horizontally. In the clearance position, the multiple support arms 203 are all at a certain angle to the horizontal plane. As an example, the multiple support arms 203 can be... Figure 1The vertical position shown ensures that the multiple support arms 203 are outside the lifting path of mold A, thus avoiding interference with mold A. Of course, this application does not limit the swing angle of the multiple support arms 203, as long as the avoidance function is achieved and the space requirements are met.

[0052] In an optional or preferred embodiment, such as Figure 2 and Figure 3 As shown, the mold conveying assembly also includes a rotating shaft connecting seat 7. Two rotary drive mechanisms 5 and two transmission shafts 6 can all be mounted on the rotating shaft connecting seat 7. Both transmission shafts 6 can rotatably pass through the rotating shaft connecting seat 7. The two rotary drive mechanisms 5 can be mounted on one side of the rotating shaft connecting seat 7 and are respectively connected to the two transmission shafts 6. The transfer drive mechanism 4 includes a guide rail 401 extending laterally and a slide table 402 that slides into contact with the guide rail 401. The rotating shaft connecting seat 7 is fixedly connected to the slide table 402. The slide table 402 can be driven by a screw drive device, chain drive device, pneumatic cylinder, hydraulic cylinder, stepper motor, or servo motor, etc. This application does not limit this, but depends on the design requirements, motion accuracy, load capacity, and economy of the conveying assembly. Thus, by sliding the slide table 402 on the guide rail 401, the rotating shaft connecting seat 7, the two transmission rotating shafts 6 and the two rotary drive mechanisms 5 can be driven to move along the arrangement direction of the multiple processing stations 1, so that the mold support structure 2 set on the transmission rotating shaft 6 can move between the multiple processing stations 1.

[0053] Furthermore, considering the relatively large length of the transmission shaft 6, in order to ensure the stability of the transmission shaft 6 along its axial movement, such as... Figure 3 As shown, a support slide rail can be provided on the processing platform, extending axially along the transmission shaft 6. The support sleeve sleeved on the transmission shaft 6 can form a sliding fit connection with the support slide rail, so that the support sleeve can move synchronously along the support slide rail when the transmission shaft 6 moves axially. Thus, on the one hand, the support sleeve can maintain support for the middle section of the transmission shaft 6, improving its stability, and on the other hand, it can prevent the bottom of the transmission shaft 6 from directly contacting the processing platform and causing wear due to friction.

[0054] In an optional or preferred embodiment, both the first support arm assembly 201 and the second support arm assembly 202 include at least one positioning support arm. The top of the positioning support arm is provided with an arm positioning structure 2031 that can form a fitting connection with the bottom of the mold A. For example, when the bottom of the mold A is provided with a positioning groove, the arm positioning structure 2031 can be a positioning block that matches the positioning groove. Thus, when the mold A is placed on the first support arm assembly 201 and the second support arm assembly 202, the positioning block on the positioning support arm can be embedded into the positioning groove of the mold A, so that the mold A and the first support arm assembly 201 and the second support arm assembly 202 will not move relative to each other in the lateral direction, thereby improving the stability of the mold A during station transfer and ensuring the transfer accuracy of the mold A. Of course, if the coefficient of friction between the mold A and the support arm 203 is sufficiently large, for example, if the upper surface of the support arm 203 is set as an anti-slip surface, it is not necessary to provide an additional positioning support arm. This application does not limit this.

[0055] In an optional or preferred embodiment, multiple first support arm assemblies 201 and multiple second support arm assemblies 202 are provided, and the multiple first support arm assemblies 201 and multiple second support arm assemblies 202 are arranged sequentially at intervals along the axial direction of the corresponding transmission shaft 6. Specifically, the number of first support arm assemblies 201 and multiple second support arm assemblies 202 can be set according to the number of processing stations 1, so as to... Figure 1 Taking the mold conveying assembly shown as an example, when there are six processing stations 1, five first support arm assemblies 201 and five second support arm assemblies 202 can be provided accordingly. The five first support arm assemblies 201 and the five second support arm assemblies 202 can simultaneously support five molds A. Specifically, the first first support arm assembly 201 and the first second support arm assembly 202 can move between the first processing station 1 and the second processing station 1, thereby transferring the mold A located at the first processing station 1 to the second processing station 1; the second first support arm assembly 201 and the second second support arm assembly 202 can move between the second processing station 1 and the third processing station 1, thereby transferring the mold A located at the second processing station 1 to the third processing station 1; and so on, so that the mold A located at the first processing station 1 can be transferred to the next processing station 1 one by one until it is transferred to the last processing station 1, thereby completing the entire processing process. Once mold A at the first processing station 1 is transferred, continuous processing production can be achieved by adding a new mold A containing the product to the first processing station 1.

[0056] In this embodiment, by setting multiple first support arm groups 201 and multiple second support arm groups 202 to transfer multiple molds A synchronously, the product production efficiency can be improved, eliminating the need to transfer multiple molds A in multiple steps.

[0057] In an optional or preferred embodiment, such as Figure 5 As shown, the mold lifting mechanism 3 includes a lead screw and nut assembly, a lifting assembly, and a lead screw drive device 305. The lead screw and nut assembly includes a lead screw 301 extending vertically and a nut 302 screwed onto the lead screw 301. The lifting assembly includes a lifting rod 303 and a lifting connecting seat 304. The lifting connecting seat 304 is fixedly connected to the nut 302, and the lifting rod 303 extends vertically and is connected to the lifting connecting seat 304. The lead screw drive device 305 drives the lead screw 301 to rotate. Therefore, when the lead screw drive device 305 drives the lead screw 301 to rotate in the forward direction, the nut 302 moves upward along the axial direction of the lead screw 301, causing the lifting connecting seat 304 to rise, thereby causing the lifting rod 303 to rise to lift the mold A located on the processing station 1 or the mold support structure 2 to a certain height; conversely, when the lead screw drive device 305 drives the lead screw 301 to rotate in the reverse direction, the lifting rod 303 descends to lower the lifted mold A onto the mold support structure 2 or the processing station 1. Of course, the rotation direction of the lead screw drive device 305 depends on the thread direction of the lead screw 301, so the rotation direction of the lead screw drive device can be determined according to the actual application, and this application does not limit it in this regard.

[0058] In this embodiment, the lead screw drive device 305 can be a rotary motor. The lifting connecting seat 304 is provided with a connecting seat through hole for the nut 302 to be nested. The nut 302 can be mounted on the lifting connecting seat 304 through a nut mounting plate, as detailed in the following reference. Figure 3 After the nut 302 is fixed on the nut mounting plate, the nut mounting plate is clamped into the through hole of the connecting seat of the lifting connecting seat 304 by the lifting clamping plate.

[0059] Furthermore, the mold lifting mechanism 3 also includes a fixed base 306, a guide rod 307, and a guide base 308. The fixed base 306 can be fixedly installed below the processing platform. The screw drive device 305 and the guide rod 307 are both fixedly connected to the fixed base 306. The lifting connecting seat 304 can be movably sleeved on the guide rod 307 in a vertical direction. For example, it can be sleeved on the guide rod 307 through a linear bearing. The guide base 308 is fixedly connected to the top of the guide rod 307. The top end of the screw 301 can be rotatably connected to the guide base 308 through a deep groove ball bearing. The lifting rod 303 can be movably inserted into the guide base 308 in a vertical direction. For example, a guide sleeve for the lifting rod 303 to pass through can be provided in the guide base 308.

[0060] Therefore, in this embodiment, the lifting connecting seat 304 can move up and down between the guide base 308 and the fixed base 306, and the lifting rod 303 extends upward through the guide base 308 to lift the mold A located on the upper processing platform. During the lifting process, the guide rod 307 can limit and guide the lifting connecting seat 304, so that the lifting rod 303 can achieve linear lifting and lowering, and is not prone to shaking during the lifting process, making the lifted mold A more stable.

[0061] In an optional or preferred embodiment, such as Figure 5 As shown, the lifting connecting seat 304 is formed as a lifting connecting plate, and the lead screw 301 is set through the center of the lifting connecting plate. Multiple lifting rods 303 can be provided, and the multiple lifting rods 303 are arranged sequentially and at intervals around the circumference of the lead screw 301 around the lifting connecting plate. By setting multiple lifting rods 303, the lifting operation of mold A can be performed more stably.

[0062] Furthermore, in this embodiment, multiple guide rods 307 may be provided. The multiple guide rods 307 are arranged sequentially and spaced apart around the circumference of the lead screw 301 on the fixed base 306 and inserted into the lifting connecting seat 304, so that the lifting connecting seat 304 can move up and down under the guidance of the multiple guide rods 307.

[0063] A second exemplary embodiment of this application provides a hot bending apparatus, which includes the aforementioned die conveying assembly for hot bending apparatus. Obviously, the hot bending apparatus of this exemplary embodiment possesses all the technical effects brought about by the aforementioned die conveying assembly, and therefore will not be described again here.

[0064] Next, let's take... Figure 1 The following is an example of the mold conveying assembly set in the hot bending equipment, illustrating the operation process of its conveying mold A.

[0065] First, it should be noted that in this embodiment, the mold conveying assembly is used to convey mold A, which is fed into the furnace body of the hot bending equipment, so that mold A can sequentially pass through multiple processing stations 1 in the furnace body to perform different processing steps. (Refer to...) Figure 1 The furnace body is equipped with six processing stations 1. From left to right, the six processing stations 1 are the first preheating station, the second preheating station, the first forming station, the second forming station, the pressure holding station, and the water cooling station. The six processing stations 1 are arranged in sequence to form a mold flow channel that extends in a straight line.

[0066] The conveying steps for mold A containing glass are as follows:

[0067] Step 1: Adjust the multiple support arms 203 of the first support arm group 201 and the second support arm group 202 to a vertical position;

[0068] Step 2: Send the mold A containing glass from the feeding chamber or the low-temperature preheating station into the first preheating station;

[0069] Step 3: Move the leftmost first support arm group 201 and second support arm group 202 to the first preheating station. At the same time, after completing the cooling process, the mold A located in the water cooling station is pushed out of the water cooling station and flows to the discharge chamber or discharge water cooling station for external water cooling.

[0070] Step 4: The mold lifting mechanism 3 is activated, and the lifting rod 303 passes through the mold flow channel and lifts the five molds A located at the first preheating station, the second preheating station, the first forming station, the second forming station, and the pressure holding station to the highest position.

[0071] Step 5: The rotary drive mechanism starts rotating in the forward direction, driving the two transmission shafts 6 to rotate inward by 90° simultaneously. The five sets of first support arm groups 201 and second support arm groups 202 then rotate inward by 90° to a horizontal state.

[0072] Step 6: The mold lifting mechanism 3 lowers the five molds A that have been lifted onto the five sets of first support arm groups 201 and second support arm groups 202 respectively. At this time, the positioning groove of mold A is engaged with the positioning block of the positioning support arm.

[0073] Step 7: The transfer drive mechanism 4 drives the two transmission shafts 6 to move to the right, so that the five molds A are moved to the next processing station 1 respectively, of which the rightmost mold A is moved to the empty water cooling station.

[0074] Step 8: The mold lifting mechanism 3 is activated, and the lifting rod 303 lifts all molds A located on the first support arm group 201 and the second support arm group 202 to the highest position;

[0075] Step 9: The rotary drive mechanism starts in reverse, driving the two transmission shafts 6 to rotate outward by 90° simultaneously. The five sets of first support arm groups 201 and second support arm groups 202 then rotate outward by 90° to the vertical position.

[0076] Step 10: The mold lifting mechanism 3 lowers the five molds A that have been lifted to the second preheating station, the first forming station, the second forming station, the pressure holding station, and the water cooling station, respectively.

[0077] Step 11: After the mold A at each workstation has been processed, return to step 2 and repeat this process.
