Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a thermosetting curing device for bonding battery casings. Background Technology

[0002] In the assembly and manufacturing of energy battery boxes, adhesive bonding is one of the mainstream technologies for connecting box components and strengthening the structure. This technology is widely used in the assembly process of various battery box components due to its ease of operation, minimal damage to the workpiece structure, and adaptability to complex connection surfaces. To ensure bond strength and meet the sealing performance and structural reliability requirements of the battery box, the industry generally adopts thermo-press curing technology for subsequent processing of the bonded parts. This involves applying pressure and controlling a specific temperature to promote the curing of the adhesive layer. Currently, mainstream thermo-press curing equipment is designed with an integrated heating structure and a fixed load-bearing positioning method as its core design concept to achieve thermo-press curing of battery box components.

[0003] However, existing hot-press curing processes and corresponding equipment still have significant technical limitations in practical applications: the heating structure of existing equipment is mostly an integral design, which is difficult to adapt to battery boxes of different sizes and specifications, and lacks a stable and precise pressurization and temperature control coordination mechanism, which can easily lead to uneven heating of the adhesive layer and unbalanced pressure distribution, resulting in uneven curing of the adhesive layer, localized bubbles or missing adhesive, etc., which ultimately affect the connection strength, sealing performance and long-term reliability of the battery box, and cannot meet the needs of large-scale production of high-quality battery boxes. Summary of the Invention

[0004] This application discloses a hot-press curing device for bonding battery boxes, which solves the technical problems of existing hot-pressing devices for battery boxes in the related art, such as poor flexibility in adapting to battery boxes of different sizes, lack of stable and precise pressure and temperature control coordination mechanism, which easily leads to uneven curing of adhesive layer, generation of bubbles or missing adhesive.

[0005] To solve the above problems, the present invention adopts the following technical solution: This invention provides a hot-press curing device for bonding battery boxes, including a frame and a hot-pressing device disposed on the top of the frame, defining the space inside the frame as a hot-pressing space; the hot-pressing device includes a pressure plate that can move vertically up and down within the hot-pressing space, and a heating splicing plate detachably disposed on the side of the pressure plate facing the hot-pressing space; the heating splicing plate is composed of multiple heating plates spliced ​​together.

[0006] Preferably, a support plate is provided in the hot-pressing space, and a hot-pressing support plate is provided on the support plate according to the shape of the battery box, and a gap is provided between the support plate and the hot-pressing support plate.

[0007] Preferably, the support plate is provided with a plurality of mounting holes, and positioning components and support columns are detachably mounted on the mounting holes; the support plate is also provided with a plurality of mounting plates through the mounting holes, and the hot-press support plate is mounted on the mounting plates.

[0008] Preferably, the support plate is provided with a plurality of mounting holes, and positioning components and support columns are detachably mounted on the mounting holes; the support plate is also provided with a plurality of mounting plates through the mounting holes, and the hot-press support plate is mounted on the mounting plates.

[0009] Preferably, the frame is further provided with a conveying mechanism, which includes a conveying frame and a conveying cylinder and a conveying track disposed on the conveying frame. The support plate is slidably disposed on the conveying track, the conveying cylinder is connected to the support plate, and at least part of the conveying frame and the conveying track are disposed within the hot-pressing space.

[0010] Preferably, the support plate has notches on opposite sides in the conveying direction of the conveying track, and the conveying frame has a buffer corresponding to the notches.

[0011] Preferably, the hot pressing device includes an electric push rod and a pressure rod mounted on the frame, the output end of the electric push rod being connected to the pressure plate; a pressure plate is mounted on the side of the pressure rod facing the hot pressing space, and a pressure sensor is mounted on the pressure plate to monitor the pressure when the pressure plate presses down and contacts the pressure plate.

[0012] Preferably, the electric push rod and the pressure rod are arranged in a matrix, with the electric push rod located at the four corners of the matrix and the pressure rod located in the middle and around the perimeter of the matrix.

[0013] Preferably, the top of the frame is also provided with a plurality of stabilizing bars, which are connected to the pressure plate and can move vertically with the pressure plate.

[0014] Preferably, a buffer rod is provided along the edge of the pressure plate, and an abutment rod is provided in the hot-pressing space corresponding to the buffer rod. When the pressure plate descends, the buffer rod abuts against the abutment rod.

[0015] Preferably, the side of the frame is provided with an openable cabinet door, and a control cabinet is also provided on the frame. The control cabinet is electrically connected to the heating splicing plate, the conveying cylinder, the electric push rod, the pressure rod and the pressure sensor.

[0016] The technical solution adopted in this invention can achieve the following beneficial effects: 1. In this technical solution, the heating splicing plate adopts a design of detachable splicing of multiple heating plates. Operators can flexibly select and arrange these heating plate modules according to the specific size and planar contour of the battery box to be processed, and quickly reconstruct the matching heating area. This enables a single device to economically and efficiently adapt to the production of battery boxes of various sizes and specifications, without the need to customize expensive integral heating molds for each size of product, which greatly reduces equipment investment costs, shortens the adjustment time for product changeover, and improves the response speed and flexibility of the production line.

[0017] 2. The heating splicing plate structure with multiple heating plates can achieve targeted heating of different bonding areas of the battery box by precisely controlling the temperature of each heating plate. This avoids the local heating dead zones or uneven temperature problems that are prone to occur in the existing integral heating structure. It ensures that the adhesive layer is heated evenly and fully cured during the hot pressing process, effectively reducing the generation of curing defects such as bubbles and insufficient adhesive. This improves the connection strength, sealing performance and long-term reliability of the battery box, meeting the production requirements of high-quality battery boxes.

[0018] 3. The detachable design of the heating splicing plate allows for direct replacement of the corresponding plate when a single heating plate fails or is damaged, without the need to replace the entire heating structure, thus reducing equipment maintenance costs and downtime for repairs. At the same time, in conjunction with the vertical lifting movement of the pressure plate, the battery box can be quickly pressed and hot-pressed for curing. Compared with natural curing and conventional hot-pressing methods, this significantly shortens the adhesive curing cycle and meets the efficiency requirements of industrial mass production.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] In existing thermo-press curing equipment used for bonding battery boxes, the heating structure is mostly an integral design, which cannot adapt to the processing needs of battery boxes of different sizes and specifications. Furthermore, the assembly rationality of the heating and pressurizing structures is insufficient, resulting in poor equipment versatility, low thermo-press curing efficiency, and difficulty in meeting the requirements of industrial mass production.

[0025] The following is in conjunction with the appendix Figures 1 to 4 The present application provides a detailed description of a thermosetting curing device 1 for bonding battery boxes through specific embodiments and application scenarios.

[0026] This invention provides a thermopress curing device 1 for bonding battery boxes, including a frame 10 and a thermopressing device 11 disposed on the top of the frame 10, defining the space inside the frame 10 as a thermopressing space 100; the thermopressing device 11 includes a pressure plate 110 that can move vertically up and down within the thermopressing space 100, and a heating splicing plate 111 detachably disposed on the side of the pressure plate 110 facing the thermopressing space 100; the heating splicing plate 111 is composed of multiple heating plates 1110 spliced ​​together.

[0027] Specifically, the frame 10 is a rectangular frame structure welded from structural steel. The hot pressing space 100 refers to the inner cavity enclosed by the frame 10, used to accommodate the battery box workpiece and perform hot pressing operations. The heating splicing plate 111 is detachably installed on the lower surface of the pressure plate 110 by bolt connection. The heating splicing plate 111 is composed of multiple independent heating plates 1110 spliced ​​together. Each heating plate 1110 is an aluminum alloy plate with an embedded heating tube. The plates are aligned by mortise and tenon structures on the sides and secured by connectors to form a complete heating plane. In practical applications, the material, single size, and number of heating plates 1110 can be selected as needed, and this embodiment does not limit this.

[0028] During operation, the battery box to be bonded, which has been coated with adhesive, is sent into the hot pressing space 100 and positioned. The pressure plate 110 moves downward under the action of the drive mechanism, which drives the heating splicing plate 111 below it to descend together until the heating splicing plate 111 contacts the upper surface of the box and applies a predetermined pressure. At the same time, the electric heating tubes in each heating plate 1110 are energized and heat up, and conduct the heat to the bonding part of the box through the contact surface. Under the combined action of pressure and heat, the adhesive is evenly coated on the bonding part, and then cooled and cured to achieve bonding.

[0029] Understandably, the use of a heating assembly plate 111, composed of multiple heating plates 1110, allows the equipment to quickly adapt to the heating needs of battery boxes of different shapes and sizes by replacing or rearranging heating plate 1110 modules of different specifications, without having to replace the entire heating device, thus improving the equipment's versatility and production flexibility. At the same time, the modular design facilitates independent control and maintenance of local heating units, laying the foundation for achieving uniform heating and reducing maintenance costs.

[0030] Furthermore, a support plate 101 is provided in the hot pressing space 100, and a hot pressing support plate 102 is provided on the support plate 101 according to the shape of the battery box, and a gap is provided between the support plate 101 and the hot pressing support plate 102.

[0031] Specifically, the support plate 101 is a horizontally arranged metal plate that is slidably installed inside the frame 10. The hot-press support plate 102 is made according to the dimensions of the main cavity of the battery box and is used to support the main body of the battery box.

[0032] Understandably, when the battery box is placed on the hot-press support plate 102, its main body can be accurately positioned and stably supported. The gap setting facilitates the wiring between the drive mechanism, the cleaning of excess adhesive, and also provides a certain degree of ventilation and heat dissipation.

[0033] Furthermore, the support plate 101 is provided with a plurality of mounting holes 1010, and positioning elements 1011 and support columns 1012 are detachably mounted on the mounting holes 1010; the support plate 101 is also provided with a plurality of mounting plates 1013 through the mounting holes 1010, and hot-pressed support plates 102 are mounted on the mounting plates 1013.

[0034] Specifically, the support plate 101 is machined with a matrix of threaded mounting holes 1010. The positioning element 1011 has a cylindrical pin. After being screwed into the designated mounting hole 1010, the part of the pin that protrudes from the support plate 101 can be inserted into the process hole at the bottom of the battery box to achieve initial horizontal positioning of the box. The support column 1012 is a height-adjustable bolt column that is screwed into or placed on the mounting hole 1010 to directly support a part of the hot-pressed support plate 102 or adjust its overall levelness. The mounting plate 1013 has a through hole at its bottom that corresponds to the mounting hole 1010 of the support plate 101. The mounting plate 1013 is fixed to the support plate 101 by bolts passing through the through hole and connecting to the mounting hole 1010. The hot-pressed support plate 102 is fixed to the upper surface of the mounting plate 1013 by bolts.

[0035] Understandably, by selecting different mounting hole 1010 positions to install the positioning component 1011, the positioning requirements of different enclosures can be quickly adapted. By installing support columns 1012 or mounting plates 1013 on the mounting holes 1010 at different positions, a support system adapted to the bottom contours of different enclosures can be flexibly constructed. The mounting plate 1013, as an intermediate connector, expands the range of fixing points for the hot-pressed support plate 102, making its installation more stable. This modular mounting hole 1010 design makes the carrier plate 101 a universal support platform. By combining different positioning components 1011, support columns 1012, mounting plates 1013, and hot-pressed support plates 102, special support fixtures suitable for various battery enclosure models can be quickly and cost-effectively configured, greatly enhancing the adaptability and configuration efficiency of the equipment.

[0036] Furthermore, a conveying mechanism 103 is also provided inside the frame 10. The conveying mechanism 103 includes a conveying frame 1030 and a conveying cylinder 1031 and a conveying track 1032 disposed on the conveying frame 1030. The support plate 101 is slidably disposed on the conveying track 1032. The conveying cylinder 1031 is connected to the support plate 101, and at least part of the conveying frame 1030 and the conveying track 1032 are disposed inside the hot pressing space 100.

[0037] Specifically, the conveyor frame 1030 is a steel structure fixedly installed on the bottom frame of the machine frame 10. The conveyor track 1032 consists of two parallel linear guide rails, respectively installed on both sides of the conveyor frame 1030. A slider is installed at the corresponding position on the bottom of the support plate 101. The slider cooperates with the linear guide rails, allowing the support plate 101 to slide back and forth along the guide rails. The conveyor cylinder 1031 is a standard double-acting cylinder, with its cylinder body fixed to one end of the conveyor frame 1030. The piston rod of the cylinder is connected to the side of the support plate 101 through a connector. Part of the conveyor track 1032 and the support plate 101 are within the hot pressing space 100, while the other part extends to the loading and unloading area outside the machine frame 10.

[0038] Specifically, during loading and unloading, the piston rod of the conveying cylinder 1031 extends, pushing the bearing plate 101 along the conveying track 1032 out of the hot pressing space 100 to the outside of the frame 10, facilitating the operator's loading and unloading of workpieces. After loading and unloading are completed, the piston rod of the conveying cylinder 1031 retracts, smoothly pulling the bearing plate 101 and the workpieces on it back to the predetermined working position within the hot pressing space 100.

[0039] Understandably, the conveying mechanism 103 enables automatic linear transfer of the bearing plate 101 and the workpiece, separates the hot pressing station from the loading and unloading station, and ensures that the hot pressing operation and manual operation do not interfere with each other, thereby improving the automation level and production efficiency of the equipment, while ensuring operational safety.

[0040] Furthermore, the support plate 101 is provided with notches 1014 on both sides of the conveying direction of the conveying track 1032, and the conveying frame 1030 is provided with a buffer 1015 corresponding to the notches 1014.

[0041] Specifically, a U-shaped notch 1014 is machined on the bottom edge of both the front and rear ends of the support plate 101. A buffer 1015 is fixedly installed on the conveyor frame 1030 at the extreme position where the corresponding support plate 101 is completely slid out or completely retracted.

[0042] As an optional implementation, the buffer 1015 may be a hydraulic buffer, a polyurethane buffer pad, or a spring buffer; in this embodiment, the buffer 1015 is a hydraulic buffer.

[0043] Understandably, when the carrier plate 101 moves to the end of its stroke under the drive of the conveying cylinder 1031, the edge of its notch 1014 will first contact the buffer 1015 installed on the conveying frame 1030. The buffer 1015 gradually absorbs and dissipates the kinetic energy of the carrier plate 101 through its own elastic deformation or damping effect, so that it stops smoothly and avoids noise, vibration and damage to the guide rail and cylinder connection components caused by rigid collision. The notch 1014 and the buffer 1015 provide reliable end buffer for the movement of the carrier plate 101, significantly reduce the impact load during equipment operation, improve the service life of transmission components, and ensure the stability of the workpiece during the conveying process.

[0044] Furthermore, the hot pressing device 11 includes an electric push rod 112 and a pressure rod 113 mounted on the frame 10. The output end of the electric push rod 112 is connected to the pressure plate 110. A pressure plate 1130 is mounted on the side of the pressure rod 113 facing the hot pressing space 100. A pressure sensor is mounted on the pressure plate 1130 to monitor the pressure when the pressure plate 1130 presses down and contacts the pressure plate 110.

[0045] Specifically, the stator of the electric push rod 112 is fixedly mounted on the crossbeam at the top of the frame 10 via a bracket, and its output end is fixedly connected to the top of the pressure plate 110 to drive the pressure plate 110 to perform vertical lifting and lowering movements. The drive mechanism of the pressure rod 113 is also a linear motion motor, consisting of multiple vertically arranged rigid rods. Its upper end is fixed to the top of the frame 10 via a mounting base, and its lower end extends into the hot pressing space 100. A circular pressure plate 1130 is installed at the lower end of each pressure rod 113. The pressure sensor is a strain gauge pressure sensor, which is embedded in the upper surface of the pressure plate 1130 or installed in the center of the pressure plate 1130 via a thread.

[0046] Specifically, during operation, the electric push rod 112 drives the pressure plate 110 to descend. When the pressure plate 110 descends to a certain height, the heated splicing plate 111 contacts the battery box to be bonded, and the adhesive is heated first. Then the pressure rod 113 descends, and the side of the pressure plate 110 facing away from the heated splicing plate 111 contacts the pressure plate 1130 extending down from above and continues to press down. At this time, the pressure sensor is squeezed, monitors in real time, and outputs a pressure signal. Based on the received pressure signal, the control system can accurately control the output of the pressure rod 113 and the electric push rod 112 to stabilize the pressure applied to the workpiece at the set value.

[0047] Understandably, the use of electric push rod 112 provides high-precision and high-response displacement and pressure control. By independently setting up pressure rod 113 with pressure sensor and pressure plate 1130, direct and real-time monitoring of the actual pressure during hot pressing is realized, providing key data support for precise closed-loop control of the process and ensuring the consistency of quality in each pressing.

[0048] Furthermore, to ensure that the pressure plate 110 is subjected to uniform force and runs smoothly when subjected to large downward pressure, and to prevent jamming or deformation due to uneven load, the electric push rod 112 and the pressure rod 113 are arranged in a matrix. The electric push rod 112 is set at the four corners of the matrix, and the pressure rod 113 is set in the middle and around the matrix.

[0049] Specifically, a rectangular area is planned on the top plane of the frame 10. Four electric push rods 112 are installed at the four corners of the rectangular area, and multiple pressure rods 113 are distributed within the rectangular area. Specifically, in this embodiment, one rod is installed at the center point of the rectangle, and one rod is installed at the midpoint of each of the four sides, so that together with the electric push rods 112 at the four corners, a uniformly distributed support and pressure matrix is ​​formed.

[0050] Understandably, the four corner electric push rods 112 provide a stable and symmetrical driving torque for the lifting and lowering of the pressure plate 110, effectively resisting any potential off-center loads. The pressure rods 113 distributed in the middle and around the perimeter share and transmit pressure after the pressure plate 110 contacts the pressure plate 1130, ensuring uniform stress on the pressure plate 110 and preventing excessive local bending moments. This matrix layout forms a rigid pressure frame. This layout significantly enhances the structural rigidity and motion stability of the hot pressing device 11, ensuring that the large-size pressure plate 110 remains horizontal throughout the entire movement, and that pressure is evenly transmitted to the entire heated splicing plate 111 and the workpiece surface, thereby achieving a uniform adhesive layer thickness and curing effect.

[0051] Furthermore, in order to prevent the pressure plate 110 from swaying or deflecting horizontally due to force or inertia during the vertical lifting and lowering process, an auxiliary guide stabilizing structure needs to be added; multiple stabilizing rods 104 are also provided on the top of the frame 10, the stabilizing rods 104 are connected to the pressure plate 110, and the stabilizing rods 104 can move vertically with the pressure plate 110.

[0052] Specifically, the stabilizer 104 is an optical axis or a linear bearing guide rod. In this embodiment, there are four rods, which are vertically installed at the four corners of the top of the frame 10. The four corners of the pressure plate 110 are provided with linear bearings or guide sleeves. The stabilizer 104 passes through these bearings or guide sleeves and is fixedly connected to the pressure plate 110. In this way, the stabilizer 104 and the pressure plate 110 form an integral moving part. When the electric push rod 112 drives the pressure plate 110 to rise and fall, the stabilizer 104 moves strictly vertically within the fixed linear bearing. The cooperation between the stabilizer 104 and the bearing restricts the degree of freedom of movement and rotation of the pressure plate 110 in any direction in the horizontal plane, and only allows it to translate in the vertical direction.

[0053] Understandably, the stabilizing bar 104 provides additional guidance and constraint for the movement of the pressure plate 110, effectively eliminating the swaying and torsion that may occur during the lifting process, ensuring the alignment accuracy of the heated splicing plate 111 when it contacts the workpiece, and improving the reliability and accuracy of the equipment movement.

[0054] Furthermore, a buffer rod 105 is provided on the edge of the pressure plate 110, and an abutment rod 106 is provided in the hot pressing space 100 corresponding to the buffer rod 105. When the pressure plate 110 descends, the buffer rod 105 abuts against the abutment rod 106.

[0055] Specifically, the buffer rod 105 is a vertical rod with a buffer pad at the lower end. Its upper part is fixed to the outer edge of the pressure plate 110 and extends downward. The abutment rod 106 is a rigid rod that is horizontally fixed to the inner wall or internal frame of the frame 10. Its installation height is calculated so that when the pressure plate 110 descends to the lower limit position (i.e., the heated splicing plate 111 contacts the workpiece and completes the pressure application), the buffer pad at the lower end of the buffer rod 105 just contacts the upper surface of the abutment rod 106.

[0056] When the pressure plate 110 descends to the lower limit position, the buffer rod 105 and the abutment rod 106 make mechanical contact. The abutment rod 106 acts as a rigid stop, limiting the pressure plate 110 from continuing to descend. The buffer pad at the end of the buffer rod 105 can absorb the small impact energy at the moment of contact.

[0057] Understandably, this mechanism provides a mechanical descent limit independent of the electrical control system as a safety redundancy for the equipment, preventing the pressure plate 110 from excessively descending and damaging the equipment or workpiece due to a control system malfunction. Simultaneously, the buffer design reduces the impact upon limit contact.

[0058] Furthermore, the side of the frame 10 is provided with an openable cabinet door 107, and the frame 10 is also provided with a control cabinet 12, which is electrically connected to the heating splicing plate 111, the conveying cylinder 1031, the electric push rod 112, the pressure rod 113 and the pressure sensor.

[0059] Specifically, the cabinet door 107 is hinged and mounted on one or more sides of the frame 10. An observation window may be provided on the door. The control cabinet 12 is mounted on the outer wall of the frame 10 and contains electrical components such as a PLC (programmable logic controller), a temperature controller, a motor driver, and a power supply module. The control cabinet 12 is connected to the heating element in the heating splicing plate 111, the solenoid valve of the transmission cylinder 1031, the driver of the electric push rod 112, and the pressure sensor on the pressure rod 113 via cables, forming a complete electrical control system.

[0060] Operators can perform internal maintenance, cleaning, or initial setup of the equipment through cabinet door 107. The PLC inside control cabinet 12, according to a preset program, coordinates and controls the extension and retraction of the conveying cylinder 1031 to achieve workpiece entry and exit, controls the raising and lowering of the electric push rod 112 to achieve pressurization, controls the on / off power supply of the heating plate 1110 to achieve heating and heat preservation, and collects signals from the pressure sensor in real time for closed-loop pressure control. In this embodiment, the PLC can be a Siemens S7-1200 series due to its high reliability and flexible programming; however, controllers from other brands can also achieve the same functions, and this application embodiment does not limit this.

[0061] Understandably, the cabinet door 107 facilitates access to and maintenance of the equipment. The integrated control cabinet 12 enables automated and programmed control of the entire hot-press curing process (transfer-pressing-heating-insulation-cooling-releasing), ensuring that process parameters are executed precisely, which is the core guarantee for achieving consistent and reliable product quality.

[0062] Specifically, the workflow of the thermosetting curing device 1 for bonding battery boxes provided in this embodiment of the invention is as follows: First, the battery box to be bonded is positioned on the hot press support plate 102 on the carrier plate 101. After the equipment is started, the conveying mechanism 103 automatically sends the carrier plate 101 and the workpiece into the hot press space 100 inside the frame 10.

[0063] Subsequently, the hot pressing device 11 is activated; the pressure plate 110 descends vertically under the drive of the electric push rod 112, and the modular heating splicing plate 111 fixed below it descends accordingly and contacts the upper surface of the battery box to achieve preheating and soften the adhesive. Then the pressure rod 113 descends to apply uniform and stable pressure to the battery box to be bonded; at the same time, each splicing heating plate 1110 is energized and heats up, accurately and evenly transferring heat to the bonding area of ​​the workpiece; the combined effect of pressure and heat significantly accelerates the curing reaction of the adhesive.

[0064] Understandably, throughout the curing cycle, the control system precisely controls the pressure (through feedback from the pressure sensor), heating temperature, and duration (heat preservation stage) according to the preset program to ensure stable process parameters. After heating and heat preservation are completed, the system enters the cooling stage, and then the pressure is released and the pressure plate 110 is raised.

[0065] Finally, the conveyor mechanism 103 operates again, sending the carrier plate 101 and the solidified battery box out of the hot pressing space 100, making it easy for the operator to pick up the parts, thus completing a fully automatic operation cycle.
