[0033] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0034] Figure 1 ​​​​​A schematic diagram of the circuit board soldering workbench provided in this embodiment is shown. This embodiment provides a circuit board soldering workbench including a platform 100 for mounting circuit boards and a support device, wherein the support device is connected to the platform 100 and is used to support and raise the platform 100 so that the position of the platform 100 is more convenient for the operator to operate, and the support device can also lock or unlock the platform 100 to fix the platform 100 when soldering the circuit board or to adjust the platform 100 when the angle of the platform 100 needs to be adjusted.

[0035] As described above, the circuit board soldering workbench includes the aforementioned support device, thus having the following effects: the locking mechanism 3 used has a higher degree of automation, which can effectively reduce the manual operation required for locking and unlocking, and quickly complete the switching of the workbench 100 from an unadjustable state to an adjustable state, thereby easily improving the efficiency of the workbench 100 when it is being adjusted and the soldering efficiency of the circuit board.

[0036] like Figure 1 As shown, Figure 1 A support device for a circuit board soldering workbench is also shown, comprising a ball joint assembly 1, a base assembly 2, and a locking mechanism 3. The ball joint assembly 1 includes a ball head member 11 for connecting to a table plate 100 of the circuit board soldering workbench and a ball socket member 12 for receiving the ball head member 11. The base assembly 2 is connected to the ball socket member 12 and supports the ball joint assembly 1 and the table plate 100. The locking mechanism 3, located within the base assembly 2, not only automatically locks the ball joint assembly 1 to prevent the ball head member 11 from rotating in the ball socket member 12, but also unlocks the ball joint assembly 1 in response to fluid pressure to allow the ball head member 11 to rotate in the ball socket member 12.

[0037] The above embodiment provides a support device for a circuit board soldering workbench. When the circuit board soldering workbench needs to be locked, the locking mechanism 3 can automatically lock the ball joint assembly 1 to prevent the ball head member 11 connected to the platform 100 of the circuit board soldering workbench from rotating in the ball socket member 12, thereby keeping the platform 100 of the circuit board soldering workbench stably locked by the ball socket member 12 to achieve the purpose of fixing the circuit board soldering workbench. When the circuit board soldering workbench needs to be adjusted, the locking mechanism 3 can automatically unlock the ball joint assembly 1 in response to fluid pressure to allow the ball head member 11 connected to the platform 100 of the circuit board soldering workbench to rotate in the ball socket member 12, so that the platform 100 of the circuit board soldering workbench can be adjusted to achieve the purpose of adjusting the circuit board soldering workbench. The locking mechanism 3 used in this support device only requires selective use of fluid pressure to lock and unlock the ball joint assembly 1. Compared with related technologies, it has a higher degree of automation, which can effectively reduce the manual operation required for locking and unlocking, and quickly complete the switching of the platform 100 from a non-adjustable state to an adjustable state, thereby easily improving the efficiency of the platform 100 when it is being adjusted and the soldering efficiency of the circuit board.

[0038] Figure 2 As shown Figure 1 The base assembly 2 and locking mechanism 3 of the support device for the circuit board soldering workbench shown are... Figure 3 As shown Figure 1 The side view of the support device for the circuit board soldering workbench shown. Figure 4 It shows Figure 3 Sectional view of BB, Figure 5 Show Figure 3 A sectional view of AA. (e.g.) Figures 2-5 and combined Figure 1As shown, the locking mechanism 3 comprises a piston chamber 31 arranged in the base assembly 2, a piston body 32 arranged in the piston chamber 31, a passage assembly 33 communicating with a rod area 311 of the piston chamber 31, an elastic member 34 arranged in a rodless area 312 of the piston chamber 31 and abutting against the piston body 32, and a top rod 35 slidably arranged in the base assembly 2, one end of the top rod 35 being connected with the piston body 32 and the other end being used for abutting against or separating from the ball head member 11 of the ball hinge assembly 1. When the fluid pressure of the passage assembly 33 increases, the piston body 32 is subjected to the fluid pressure and approaches the bottom of the rodless area 312 while compressing the elastic member 34, at this time, the volume of the rodless area 312 gradually decreases and the volume of the rod area 311 gradually increases to drive the end of the top rod 35 used for abutting against or separating from the ball head member 11 away from the ball head member 11, so as to realize that the locking mechanism 3 can respond to the fluid pressure to unlock the ball hinge assembly 1. When the fluid pressure of the passage assembly 33 decreases, since the fluid pressure acting on the piston body 32 also decreases, at this time, the restoring force of the elastic member 34 can overcome the resistance of the fluid pressure and promote the piston body 32 to move away from the bottom of the rodless area 312, at this time, the volume of the rodless area 312 gradually increases and the volume of the rod area 311 gradually decreases to drive the end of the top rod 35 used for abutting against or separating from the ball head member 11 to abut against the ball head member 11, so as to realize that the locking mechanism 3 can automatically lock the ball hinge assembly 1. On the one hand, the ball hinge assembly 1 is locked by means of the elastic member 34, which can avoid the instability of the gas pressure when the piston body 32 is driven to move by the traditional fluid pressure (such as gas), so as to avoid that the locking mechanism 3 cannot maintain good stability when locking the ball hinge assembly 1, and the problem that the table plate 100 of the circuit board welding operation table tilts when working. On the other hand, the elastic member 34 has the characteristic of restoring force, which discards the traditional method of driving the piston body 32 to move by the fluid pressure (such as gas), so as to reduce the consumption of energy.

[0039] Preferably, the elastic member 34 comprises a plurality of return springs which are evenly and dispersedly arranged in the rodless area 312 of the piston chamber 31. The plurality of return springs can simultaneously act on the piston body 32, so that the piston body 32 can be subjected to uniform thrust force, and the service life of the return springs is long, which can ensure that the locking mechanism 3 can still effectively and stably lock the ball hinge assembly 1 after being used for many times.

[0040] Further, the supporting device further comprises a sealing rubber ring 4 fixedly arranged on the piston body 32 and located between the piston chamber 31 and the piston body 32, which can improve the sealing property between the rodless area 312 and the rod area 311, so as to prevent the fluid flowing into the rod area 311 from the passage assembly 33 from flowing into the rodless area 312.

[0041] Further, a plurality of positioning grooves 313 are provided on the bottom of the rodless area 312 of the piston chamber 31, and the bottom of the return spring is accommodated in the positioning grooves 313 one by one. The groove wall of the positioning groove 313 can position the return spring to prevent the return spring from being deviated when being compressed or restored to the pre-compressed state, so that the piston body 32 cannot be subjected to the uniform thrust of the return spring, thereby ensuring that the locking mechanism 3 can still effectively and stably lock the ball hinge assembly 1 after being used for many times.

The reversing valve 331 comprises a first working state and a second working state. When the reversing valve 331 is in the first working state, the inlet port 3312 of the reversing valve 331 is in communication with the working port 3311, and the fluid received by the second radial bore 336 can flow into the rod region 311 of the piston chamber 31 in sequence through the second axial bore 333, the reversing valve 331, the first axial bore 332, and the first radial bore 335, so as to realize the injection of fluid into the rod region 311, thereby facilitating the unlocking of the ball hinge assembly 1 by the locking mechanism 3 in response to the fluid pressure. When the reversing valve 331 is in the second working state, the outlet port 3313 of the reversing valve 331 is in communication with the working port 3311, and the fluid in the rod region 311 of the piston chamber 31 can flow out of the base assembly 2 in sequence through the first radial bore 335, the first axial bore 332, the reversing valve 331, the third axial bore 334, and the third radial bore 337, so as to realize the extraction of fluid from the rod region 311, thereby facilitating the automatic locking of the ball hinge assembly 1 by the locking mechanism 3.
