Description

Technical Field

[0001] This application relates to the field of product assembly tooling technology, and in particular to a pressure holding device. Background Technology

[0002] In the assembly process of electronic products, it is often necessary to bond two different components with adhesive. Sufficient pressure must be applied to both components during bonding to ensure proper alignment and assembly accuracy. This bonding process needs to be maintained for a period of time to allow the adhesive to fully cure, ultimately connecting and fixing the two components in a specific positional relationship to form a complete product. This bonding process is generally achieved through a pressure-holding procedure using a pressure-holding device.

[0003] In actual production, workpieces typically require pressure holding at multiple locations, with varying pressure requirements and holding times for each angle. Furthermore, for irregular products requiring multi-point, multi-pressure holding, due to the product's unique shape and the need for multiple pressure parameters, the commonly used pressure holding equipment in the industry can only hold one location. Multiple pressure holding devices are needed to complete the pressure holding work at multiple locations, resulting in low pressure holding efficiency and high costs. While some pressure holding devices can simultaneously hold multiple locations, the holding pressure and time are identical, leading to poor pressure holding results. Utility Model Content

[0004] This application provides a pressure holding device that solves the problem that existing pressure holding devices use different pressure holding pressures and holding times for multiple positions of a product, which easily leads to low pressure holding efficiency, high pressure holding cost, and poor pressure holding effect.

[0005] This utility model is implemented as follows: a pressure-holding device includes a mounting frame, a lower pressing assembly, and a pressing mold assembly. The mounting frame includes a base, a top plate, and two support columns spaced apart from each other between the base and the top plate. The lower pressing assembly includes a connecting frame disposed on the top plate, a first driving member connected to the connecting frame, and a lower pressing member penetrating the top plate and connected to the driving end of the first driving member. The first driving member is used to drive the lower pressing member to move closer to or away from the base. The pressing mold assembly includes a separable upper pressing mold and a lower pressing mold, which, when connected, enclose a receiving space for accommodating a product. The upper pressing mold includes a fixed plate connected to the lower pressing member, a pressure plate connected to the fixed plate, a pressure sheet connected to the pressure plate, a second driving member connected to the top plate, and a pressing head penetrating the pressure plate and elastically connected to the driving end of the second driving member. The height of the pressing head is greater than the height of the pressure sheet. The lower pressing mold is disposed on the base and includes a bearing plate and a carrier disposed on the bearing plate. The carrier is used to carry the product to be pressure-held.

[0006] In one embodiment, the drive shaft of the second drive member is connected to a linear bearing, and the pressure head is connected to the linear bearing via a connecting rod.

[0007] In one embodiment, the fixing plate and the pressure plate are connected by an elastic element.

[0008] In one embodiment, the pressure plate has a clearance groove on the side away from the top plate. The clearance groove is used to avoid parts of the product to be pressed when the pressure plate presses down on the product to be pressed.

[0009] In one embodiment, the pressing assembly further includes a positioning rod extending through the top plate, one end of the positioning rod having a positioning block and the other end connected to the fixing plate.

[0010] In one embodiment, the number of positioning rods is four, and the four positioning rods are respectively connected to the four corners of the fixing plate.

[0011] In one embodiment, the base is provided with a transmission device, and the pressing mold is disposed on the transmission device. The transmission device is used to carry and transmit the pressing mold along a first direction; the first direction is perpendicular to the arrangement direction of the two support columns.

[0012] In one embodiment, the pressure plate is provided with a positioning pin, and the bearing plate is provided with a positioning hole. The positioning pin is inserted into the positioning hole so that the product to be pressurized is located in the receiving space.

[0013] In one embodiment, the pressure plate is detachably connected to the pressure plate, and the pressure head is detachably connected to the connecting rod.

[0014] In one embodiment, the pressing mold further includes a positioning member disposed on the carrier plate, the positioning member being used to abut against the product to be pressurized when the carrier carries the product to be pressurized.

[0015] In one embodiment, there are multiple pressing components, and the multiple pressing components are arranged side by side along the arrangement direction of the two support columns;

[0016] The number of the molding assemblies is multiple, and the multiple molding assemblies are arranged side by side along the arrangement direction of the two support columns.

[0017] The beneficial effects of the pressure-holding device provided in this application are as follows: Compared with the prior art, this application sets a lower pressing component on the top plate of the mounting frame, connects the upper pressing mold with the lower pressing component, sets the lower pressing mold on the base of the mounting frame, and drives the lower pressing component to move towards the base through the first driving component of the lower pressing component, so that the upper pressing mold and the lower pressing mold are connected and enclosed to form a receiving space for accommodating the product. Since the pressure plate is connected to the lower pressing component, and a pressure plate is connected to the pressure plate, in addition, the pressure head set through the pressure plate is driven by the second driving component connected to the top plate to place the product to be pressure-held in the receiving space. The pressure plate and pressure head of the upper pressing mold and the carrier of the lower pressing mold squeeze the two components contained in the product to be pressure-held together to achieve pressure holding of the product. The pressure plate connected to the pressure plate is used to maintain overall pressure on the product to be pressured. The movement of the pressure plate is driven by the first driving component. The pressure head is used to maintain pressure on a local part of the product to be pressured, and the movement of the pressure head is driven by the second driving component. Therefore, the pressure range of the pressure plate and the pressure head are different. Since they are driven by independent driving components, the pressure and time of the pressure plate and the pressure head can be freely adjusted according to the specific needs of the product to be pressured. This is beneficial for achieving separate pressure maintenance for the same product, which not only improves the pressure maintenance efficiency but also reduces the pressure maintenance cost and improves the pressure maintenance effect.

[0032] This application provides a pressure holding device that solves the problem that existing pressure holding devices use different pressure holding pressures and holding times for multiple positions of a product, which easily leads to low pressure holding efficiency, high pressure holding cost, and poor pressure holding effect.

[0033] refer to Figure 1 and Figure 2 The pressure-holding device provided in this application includes a mounting frame 1, a pressing assembly 2, and a pressing mold assembly. The mounting frame 1 includes a base 11, a top plate 12, and two mutually spaced support columns 13 connecting the base 11 and the top plate 12. The pressing assembly 2 includes a connecting frame 21 disposed on the top plate 12, a first driving member 22 connected to the connecting frame 21, and a pressing member 23 penetrating the top plate 12 and connected to the driving end of the first driving member 22. The first driving member 22 is used to drive the pressing member 23 to move closer to or away from the base 11. The pressing mold assembly includes an upper pressing mold 3 and a lower pressing mold 4 that can be detachably connected. When the upper mold 3 and the lower mold 4 are connected, they enclose a space for accommodating the product. The upper mold 3 includes a fixed plate 31 connected to the lower mold 23, a pressure plate 32 connected to the fixed plate 31, a pressure sheet 320 connected to the pressure plate 32, a second driving member 33 connected to the top plate 12, and a pressure head 34 that passes through the pressure plate 32 and is elastically connected to the driving end of the second driving member 33. The height of the pressure head 34 is greater than the height of the pressure sheet 320. The lower mold 4 is mounted on the base 11. The lower mold 4 includes a support plate 41 and a carrier 42 mounted on the support plate 41. The carrier 42 is used to carry the product to be pressurized.

[0034] In this application, the product to be pressurized by the pressurizing device is a semi-finished product formed by bonding two parts together with adhesive, and the bonding strength is relatively small.

[0035] The specific process of the pressure-holding device in this embodiment of the application for holding the pressure on the product to be held is as follows: The product to be held is placed on the carrier 42 of the lower mold 4. The lower mold 23 is driven by the first driving member 22 to move towards the base 11. The fixing plate 31 connected to the lower mold 23 also moves towards the base 11. Thus, the pressure plate 32 connected to the fixing plate 31 moves towards the base 11, thereby causing the pressure plate 320 connected to the pressure plate 32 to press down on the product to be held. The pressure head 34, which is provided through the pressure plate 32, is driven by the second driving member 33 connected to the top plate 12 to move towards the base 11, thereby pressing on the product to be held. The product to be held is fixed in the accommodating space formed by the upper mold 3 and the lower mold 4 under the action of the pressure plate 320 or the pressure head 34. By applying different pressures to the product to be held and maintaining them for corresponding durations by the pressure plate 320 and the pressure head 34, the purpose of holding the product to be held can be achieved. After the pressure holding is completed, the first driving component 22 drives the lower pressing component 23 to move away from the base 11. The fixing plate 31 connected to the lower pressing component 23 and the pressure plate 32 connected to the fixing plate 31 will also move away from the base 11. In this way, the pressure plate 320 connected to the pressure plate 32 will move away from the base 11 and leave the product to be pressured. At the same time, the second driving component 33 will drive the pressure head 34 to move away from the base 11 to leave the product to be pressured. After the pressure plate 320 and the pressure head 34 have both left the product to be pressured, the operator can take out the product to be pressured from the carrier 42 after the pressure holding is completed.

[0036] It should be noted that the tablet press 320 and the pressure head 34 of this application are driven separately by different driving components, so that the tablet press 320 and the pressure head 34 can be pressured separately for the product to be pressured. This allows the overall pressure holding and partial pressure holding of the product to be pressured to be realized on the same pressure holding device, which greatly improves the pressure holding efficiency of the product to be pressured and also reduces the pressure holding cost of the product to be pressured.

[0037] It is understandable that the tablet press 320 can perform overall pressure holding of the product to be held, and the press head 34 can perform partial pressure holding of the product to be held, either separately or simultaneously.

[0038] The specific implementation method for simultaneously pressing the product to be pressed by the tablet 320 and the pressure head 34 is as follows: the first driving member 22 drives the lower pressing member 23 to move closer to the base 11, and at the same time, the second driving member 33 also drives the pressure head 34 to move closer to the base 11. Since the height of the pressure head 34 is greater than the height of the tablet 320, that is, the distance between the pressure head 34 and the product to be pressed is greater than the distance between the tablet 320 and the product to be pressed, under the driving force of the first driving member 22, the tablet 320 will first press on the product to be pressed, thus pressing the product to be pressed. The product is fixed on the carrier 42, and then the pressure head 34, under the driving force of the second driving member 33, presses down on a local position of the product to be pressured, so as to maintain pressure on a local position of the product to be pressured. The pressure plate 320 and the pressure head 34 press down on the product to be pressured at the same time, and the pressure and duration of the pressure plate 320 pressing on the product to be pressured can be freely adjusted. The pressure and duration of the pressure head 34 pressing on the local position of the product to be pressured can also be freely adjusted. In this way, the overall pressure and local pressure of the product to be pressured can be performed simultaneously, improving the pressure holding efficiency of the product to be pressured.

[0039] The specific implementation method for press 320 and press head 34 to press the product to be pressed in sequence can be as follows: The first driving member 22 drives the lower pressing member 23 to move closer to the base 11, so that the press 320 presses on the product to be pressed, fixing the product to be pressed on the carrier 42. The press 320 maintains a suitable pressing pressure and presses on the product to be pressed for a suitable pressing time, so that the product to be pressed completes the overall pressing work. At this time, the first driving member 22 can drive the lower pressing member 23 to move the pressure plate 32 away from the base 11, so that the press 320 leaves the product to be pressed, or the press 320 can continue to press on the product to be pressed. On the pressure-holding product; during the pressing process of the tablet 320, the pressure head 34 also presses down. However, since the pressure head 34 is higher than the tablet 320, the pressure head 34 will not contact the product to be pressure-holded. Then, the second driving member 33 drives the pressure head 34 to move closer to the base 11. The pressure head 34 maintains a suitable pressure-holding pressure and a suitable pressure-holding time when pressing the product to be pressure-holded, so that the product to be pressure-holded completes the pressure-holding work at a local position. At this time, the second driving member 33 drives the pressure head 34 to leave the product to be pressure-holded. At the same time, the first driving member 22 also drives the pressing member 23 to move the pressure plate 32 away from the base 11, so that the tablet 320 leaves the product to be pressure-holded.

[0040] Of course, the specific implementation method of pressing the tablet 320 and the pressing head 34 in sequence to press the product to be pressed can also be as follows: the second driving member 33 drives the pressing head 34 to move towards the base 11, and the pressing head 34 maintains a suitable pressing pressure and presses down on the product to be pressed for a suitable pressing time, so that the product to be pressed completes the pressing work at a local position. At this time, the second driving member 33 can drive the pressing head 34 away from the product to be pressed, or the pressing head 34 can continue to press on the product to be pressed; during the pressing process of the tablet 320, the tablet 320 remains stationary, and then... Then, the first driving member 22 drives the lower pressing member 23 to move closer to the base 11, so that the pressing plate 320 presses on the product to be pressed, fixing the product to be pressed on the carrier 42. The pressing plate 320 maintains a suitable pressing pressure and presses down on the product to be pressed for a suitable pressing time, so that the product to be pressed completes the overall pressing work. At this time, the first driving member 22 drives the lower pressing member 23 to move the pressure plate 32 away from the base 11, so that the pressing plate 320 leaves the product to be pressed. At the same time, the second driving member 33 also drives the pressure head 34 to leave the product to be pressed.

[0041] In practical applications, the pressure-holding equipment of this application can be used in conjunction with other production devices. For example, after the initial bonding of two parts bonded together, the product to be pressure-held can be directly transferred to the pressure-holding equipment via a transfer track. Specifically, it is transferred from one side of the pressure-holding equipment to the carrier 42 along a direction perpendicular to the arrangement direction of the two support columns 13. After the pressure holding is completed, it is transferred out from the other side of the pressure-holding equipment. The product to be pressure-held after pressure holding can be directly transferred to the assembly line. After the product to be pressure-held on the carrier 42 is removed, the next product to be pressure-held can be transferred to the carrier 42 for pressure holding. In this way, continuous pressure holding of batch products can be realized, which greatly improves the pressure holding efficiency of batch products.

[0042] In some embodiments, reference Figure 3 The drive shaft of the second drive component 33 is connected to a linear bearing, and the pressure head 34 is connected to the linear bearing via a connecting rod 340.

[0043] Linear bearings are a type of low-cost linear motion system used in conjunction with cylindrical shafts for unlimited travel. They are widely used in sliding components of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery. Because the bearing balls make point contact with the bearing outer sleeve, the steel balls roll with minimal frictional resistance. Therefore, linear bearings have low friction, are relatively stable, and do not change with bearing speed, resulting in smooth linear motion with high sensitivity and precision.

[0044] With the above settings, when the first driving member 22 drives the pressing member 23 to move the pressure plate 32 towards the base 11, and the second driving member 33 is not activated, the pressure plate 320 connected to the pressure plate 32 will press down on the product to be pressed as the pressure plate 32 is pressed down. At the same time, since the pressure head 34 is set through the pressure plate 32, the pressure head 34 will also move towards the base 11 as the pressure plate 32 is pressed down. The linear bearing allows the pressure head 34 to move with the pressure plate 32 when the second driving member 33 is not activated. It should be noted that when the second driving member 33 is not activated, although the pressure head 34 will move with the pressure plate 32, since the pressure head 34 is higher than the pressure plate 320, the pressure head 34 will not apply pressure to the product to be pressed when the pressure plate 320 is pressed on the product to be pressed.

[0045] In some embodiments, reference Figure 2 The fixing plate 31 and the pressure plate 32 are connected by the elastic element 35.

[0046] The elastic element 35 can be a spring, an elastic sheet, or other elastic object.

[0047] With the above settings, the pressure plate 32 is connected to the fixed plate 31 via the elastic element 35. When the pressure plate 320 connected to the pressure plate 32 presses on the product to be pressed, if the pressure is too high, it will squeeze and shrink the elastic element 35. Thus, the elastic element 35 will apply an elastic force to the product to be pressed, which not only positions the product to be pressed more stably on the carrier 42, but also avoids the pressure plate 320 connected to the pressure plate 32 from applying too much force to the product to be pressed, which could damage the product due to the lack of buffer.

[0048] It should be noted that the elastic element 35 connecting the fixed plate 31 and the pressure plate 32 can be connected to the middle position of the pressure plate 32. This can balance the pressure of the pressure plate 320 on the product to be pressure-held, resulting in a better pressure-holding effect. Furthermore, to prevent the pressure plate 32 from shaking during the pressing process, a connecting post can be connected to each of the four corners of the pressure plate 32. The connecting post passes through the fixed plate 31, and the part passing through the fixed plate 31 is connected to a linear bearing. In this way, the connecting post can move towards the base 11 as the pressure plate 32 moves towards the base 11, and it can also stabilize the movement of the pressure plate 32, making the pressure plate 320 press more stably on the product to be pressure-held.

[0049] In some embodiments, reference Figure 4 The pressure plate 32 is provided with a relief groove 310 on the side away from the top plate 12. The relief groove 310 is used to avoid the parts of the product to be pressed when the pressure plate 32 presses down on the product to be pressed.

[0050] It should be noted that, since the pressure-holding part of the two components of the product to be pressure-held is bonded together, the middle area of ​​the product to be pressure-held is distributed with some parts of the two components. These parts protrude from the perimeter of the product to be pressure-held. Therefore, the application provides a relief groove 310 on the pressure plate 32 so that when the pressure plate 32 is pressed down, the parts distributed in the middle area of ​​the product to be pressure-held are placed in the relief groove 310. This allows the pressure plate 320 connected to the pressure plate 32 around the relief groove 310 to press smoothly onto the product to be pressure-held to apply pressure and hold the product. In this way, the parts of the product to be pressure-held will not be damaged during the pressure-holding process, and the normal use of the product after the pressure-holding is completed will not be affected.

[0051] In some embodiments, reference Figure 2 The pressing component 2 also includes a positioning rod 24 that passes through the top plate 12. One end of the positioning rod 24 is provided with a positioning block 241, and the other end is connected to the fixing plate 31.

[0052] With the above settings, when the first driving member 22 drives the lower pressing member 23 to move the fixed plate 31 towards the base 11, the positioning rod 24 connected to the fixed plate 31 will also move towards the base 11. Since the positioning rod 24 passes through the top plate 12, the moving direction of the positioning rod 24 is the thickness direction of the top plate 12. This allows the fixed plate 31 to also move towards the base 11 along the thickness direction of the top plate 12. Furthermore, the fixed plate 31 will not shake or change its moving direction during the movement towards the base 11. This allows the pressure plate 32 connected to the fixed plate 31 to move towards the base 11 at a uniform and stable speed along the thickness direction of the top plate 12. This facilitates the precise pressing of the pressure plate 320 onto the overall pressure-holding area of ​​the product to be pressured, while also ensuring that the components distributed in the middle area of ​​the product to be pressured are within the clearance groove 310 of the pressure plate 32, preventing damage.

[0053] Furthermore, when the pressure plate 32 does not shift relative to the product to be pressurized, the pressure head 34, which penetrates the pressure plate 32, can precisely press onto the localized area of ​​the product requiring pressurization, thereby improving the pressurization effect at that localized area. This allows for accurate pressurization of both the entire product and specific areas, enhancing the overall pressurization effect.

[0054] In some embodiments, reference Figure 2 There are four positioning rods 24, and the four positioning rods 24 are respectively connected to the four corners of the fixing plate 31.

[0055] It should be noted that by connecting the lower pressure member 23 to the middle position of the fixed plate 31 and connecting the four positioning rods 24 to the four corners of the fixed plate 31 respectively, when the lower pressure member 23 drives the fixed plate 31 to move closer to the base 11, it can restrict the fixed plate 31 from moving in any direction perpendicular to the thickness direction of the top plate 12, ensuring that the fixed plate 31 will not shake during the movement towards the base 11. Consequently, the movement direction of the pressure plate 32 connected to the fixed plate 31 will not change. This is beneficial for the pressure plate 320 to accurately press on the overall pressure-holding area of ​​the product to be pressured, and at the same time, it can ensure that the components distributed in the middle area of ​​the product to be pressured are within the clearance groove 310 of the pressure plate 32 to prevent damage.

[0056] In some embodiments, reference Figure 1 The base 11 is provided with a transmission device 5, and the lower pressing mold 4 is provided on the transmission device 5. The transmission device 5 is used to carry and transmit the lower pressing mold 4 along the first direction; the first direction is perpendicular to the arrangement direction of the two support columns 13.

[0057] It should be noted that the lower pressure mold 4 can be moved in the first direction by the transmission device 5. When the pressure holding equipment is in use, the lower pressure mold 4 can be transferred to one side of the support column 13 in the first direction by the transmission device 5. The operator can place the product to be pressure held on the carrier 42 and fix the product to be pressure held on the carrier 42 by the positioning part 44. Then the transmission device 5 transfers the lower pressure mold 4 to the pressure holding position, which is the position opposite to the upper pressure mold 3. After the product to be pressure held is pressure held, the lower pressure mold 4 can be transferred to the other side of the support column 13 in the first direction by the transmission device 5. The operator removes the product to be pressure held from the carrier 42. Then the transmission device 5 transfers the lower pressure mold 4 to one side of the support column 13 in the first direction. The operator continues to place the product to be pressure held on the carrier 42. In this way, the pressure holding of the product to be pressure held can be carried out continuously without interruption, realizing the continuous pressure holding work of batch products and greatly improving the pressure holding efficiency of batch products.

[0058] In some embodiments, reference Figure 1 and Figure 2 The pressure plate 32 is provided with a positioning pin 36, and the bearing plate 41 is provided with a positioning hole 43. The positioning pin 36 is inserted into the positioning hole 43 so that the product to be pressure-held is located in the receiving space.

[0059] It should be noted that since the lower mold 4 can move along the first direction, after the worker places the product to be pressurized on the carrier 42, when the transmission device 5 transmits the lower mold 4 to the pressurizing position, the lower mold 4 may deviate from the accurate pressurizing position. At this time, the upper mold 3 cannot connect with the lower mold 4 to form a space to accommodate the product to be pressurized when it presses down, and the pressure plate 320 and the pressure head 34 cannot effectively and accurately press the product to be pressurized. In this application, a positioning pin 36 is provided on the pressure plate 32, and a positioning hole 43 is provided on the carrier plate 41. When the pressure plate 32 moves towards the base 11 to press the pressure plate 320 down on the product to be pressurized, the positioning pin 36 will first be inserted into the positioning hole 43. This ensures that the lower mold 4 is in the accurate pressurizing position and has not deviated from the accurate pressurizing position. Thus, the pressure plate 320 can accurately press on the overall pressurizing position of the product to be pressurized, and the pressure head 34 can accurately press on the local pressurizing position of the product to be pressurized, so that the pressurizing effect of the product to be pressurized is guaranteed.

[0060] Furthermore, when the pressure plate 32 and the pressure sheet 320 connected to the pressure plate 32 press down on the product to be pressed, the positioning pin 36 will insert into the positioning hole 43, thereby limiting the pressure plate 32 from pressing further down. At this time, the product to be pressed is fixed between the pressure sheet 320 and the carrier 42. The positioning pin 36 can limit the distance that the pressing member 23 can move towards the base 11, preventing the pressing member 23 from continuing to press the pressure sheet 320 down after the pressure sheet 320 has already pressed the product to be pressed onto the carrier 42, which would cause the product to be pressed to be damaged due to excessive pressure.

[0061] The number of locating pins 36 can be multiple, and the number of locating holes 43 is equal to the number of locating pins 36. Each locating pin 36 is inserted into one locating hole 43. (Reference) Figure 2 The number of positioning pins 36 is set to two, which are distributed on opposite sides of the pressure plate 32. Two positioning holes 43 are provided on the bearing plate 41, and the two positioning holes 43 correspond one-to-one with the two positioning pins 36, so that the positioning pins 36 can be inserted into the positioning holes 43.

[0062] In some embodiments, the pressure plate 320 is detachably connected to the pressure plate 32, and the pressure head 34 is detachably connected to the connecting rod 340. Thus, when using the pressure-holding device of this application to hold different products under pressure, different pressure plates 320 and pressure heads 34 can be replaced. This allows the shape of the replaced pressure plate 320 to better match the shape of the different products under pressure, and the replaced pressure head 34 to better match the size of the local pressure-holding position of the different products under pressure. Therefore, the pressure-holding device can independently hold the entire product and its local portions under pressure, improving the versatility of the pressure-holding device.

[0063] In some embodiments, reference Figure 1The lower pressure mold 4 also includes a positioning element 44 disposed on the support plate 41. The positioning element 44 is used to abut the product to be pressurized when the carrier 42 carries the product to be pressurized.

[0064] It should be noted that the positioning component 44 can fix the product to be pressure-held on the carrier 42, so as to prevent the product to be pressure-held from moving when the pressure plate 320 or pressure head 34 is pressed down, which would cause the pressure plate 320 or pressure head 34 to be unable to accurately apply pressure to the position of the product to be pressure-held, thus affecting the pressure-holding effect.

[0065] Specifically, there are multiple positioning elements 44, which can be evenly distributed around the carrier 42. This allows them to support the product to be pressurized from multiple angles, so that the product to be pressurized is more stably fixed on the carrier 42.

[0066] In some embodiments, the positioning member 44 is detachably mounted on the support plate 41. This allows the mounting position of the positioning member 44 on the support plate 41 to be changed when the product to be pressurized changes, i.e., adjusting the relative position between the positioning member 44 and the carrier 42. This allows the adjusted positioning member 44 to adapt to the changed shape of the product to be pressurized, thus better securing the product. This facilitates the pressurizing equipment to pressurize different products, effectively improving the versatility of the pressurizing equipment. Compared to the prior art where a single product to be pressurized can only be pressurized by a specific pressurizing equipment, and different products require different pressurizing equipment, increasing pressurizing costs, the pressurizing equipment of this embodiment can pressurize different products, greatly reducing the cost of pressurizing different products and improving the efficiency of pressurizing different products.

[0067] In practical applications, a fixing block can be used as a positioning element 44. Once the fixing block is set, its position cannot be adjusted. If the position needs to be adjusted, the fixing block needs to be disassembled and repositioned in another position. Setting multiple fixing blocks around the carrier 42 at the same time can better fix the product to be pressure-held on the carrier 42.

[0068] In some embodiments, the positioning member 44 is disposed on the support plate 41 and the positioning member 44 is movable relative to the carrier 42.

[0069] The aforementioned positioning component 44 includes a fixing component and a movable positioning block elastically connected to the fixing component. Under the elastic force of the elastic component 35, the movable positioning block can move closer to or away from the carrier 42. Thus, when the product to be pressed is placed on the carrier 42, the product to be pressed will squeeze the movable positioning block towards the fixing component, and the elastic force generated by the elastic component 35 will be applied to the product to be pressed, thereby making the product to be pressed better fixed on the carrier 42.

[0070] In some embodiments, there are multiple pressing components 2, which are arranged side by side along the arrangement direction of the two support columns 13; there are also multiple pressing mold components, which are arranged side by side along the arrangement direction of the two support columns 13.

[0071] It should be noted that if a pressing component 2 and a molding component are regarded as a pressure holding group, then this application sets multiple pressing components 2 and multiple molding components, which is equivalent to setting multiple pressure holding groups. The multiple pressure holding groups are arranged side by side along the arrangement direction of the two support columns 13. Each pressure holding group presses one product to be pressurized at a time. Thus, multiple pressure holding groups can press multiple products to be pressurized at the same time, which greatly improves the pressure holding efficiency of batch products to be pressurized.

[0072] Example, reference Figure 1 The pressing component 2 is set to two, and the pressing mold component is also set to two. In actual production, the connecting frame 21 of the two pressing components 2 can be set to the same one, and the first driving component 22 of the two pressing components 2 can be connected to the same connecting frame 21. This can reduce the workload of installing the connecting frame 21 on the top plate 12, improve the assembly efficiency of the pressing component 2, and also reduce costs.

[0073] The two pressing die assemblies are arranged side by side along the arrangement direction of the two support columns 13. That is, the two upper pressing dies 3 are arranged side by side along the arrangement direction of the two support columns 13, and the two lower pressing dies 4 are also arranged side by side along the arrangement direction of the two support columns 13. This makes it easier for the operator to carry out the work when the conveying device 5 conveys the two lower pressing dies 4 together to one side of the support column 13 for loading or to the other side of the support column 13 for unloading.

[0074] In some embodiments, the number of pressing components 2 is multiple, and the multiple pressing components 2 are arranged side by side along the first direction; the number of pressing mold components is also multiple, and the multiple pressing mold components are arranged side by side along the first direction. This also enables the pressure holding device to simultaneously pressure multiple products to be pressured, thereby improving the pressure holding efficiency of batch products to be pressured. At the same time, since the conveying device 5 conveys the pressing molds 4 along the first direction, the side-by-side arrangement of multiple pressing molds 4 along the first direction will not affect the operator's ability to place the products to be pressured on the carrier 42 and remove the pressure-pressed products from the carrier 42.

[0075] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
