Description

Technical Field

[0001] This utility model relates to the field of circuit board transfer technology, specifically a transfer device for conveying circuit boards, which is particularly suitable for the safe transfer, isolation and protection, and multi-group stacking of multi-layer high-precision circuit boards. It can be widely used in multi-process material flow scenarios in electronic component production workshops. Background Technology

[0002] In the circuit board manufacturing process, semi-finished or finished circuit boards need to be transferred through multiple processes. Existing circuit board transfer devices mostly use simple pallet or turnover box structures, which have the following shortcomings:

[0003] 1. The lack of multi-layer independent isolation and shock absorption structure makes it easy for adjacent circuit boards to scratch the board surface due to friction during transportation, and vibration can easily cause the circuit board solder joints to fall off and the circuit to be damaged.

[0004] Second, when stacking multiple groups, the positioning accuracy is poor. Relying solely on the alignment of the box's shape can easily lead to horizontal shifting or tipping risks.

[0005] Third, the sealing and locking operations are cumbersome, and most devices need to be fixed with bolts or clips, resulting in low disassembly and assembly efficiency.

[0006] Fourth, the unreasonable design of the handling structure, with some devices lacking dedicated handles or having protruding handles that affect stacking, increases the difficulty of handling and storage. Therefore, a transfer device for conveying circuit boards is proposed to solve the above-mentioned problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a transfer device for conveying circuit boards, which has the advantages of multi-layer independent storage and isolation, comprehensive shock absorption and protection, accurate stacking and positioning, convenient locking operation, and flexible handling and storage. It solves the problems of existing transfer devices that easily scratch circuit boards, damage components due to vibration, unstable stacking, cumbersome locking, and inconvenient handling.

[0009] (II) Technical Solution

[0010] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A transfer device for conveying circuit boards includes a base frame, a set of storage mechanisms is inserted into the top of the base frame, a closing mechanism is inserted into the top of the storage mechanism, and four locking mechanisms are provided on the top of the base frame and engaged with the closing mechanism.

[0011] The base frame includes a chassis, and four rods arranged in a rectangular array are fixedly connected to the top of the chassis. The top of the chassis is provided with shock-absorbing grooves adapted to the storage mechanism.

[0012] One set of the storage mechanism includes three transfer trays, which are used to store circuit boards;

[0013] The four locking mechanisms are respectively rotatably connected to the top of the four insert rods;

[0014] The closing mechanism includes a cover plate, and the top of the cover plate has four slots that are adapted to the locking mechanism.

[0015] The slot is used to close the top of the storage mechanism after the locking mechanism is rotated 90 degrees, in conjunction with the cover plate.

[0016] The beneficial effects of this utility model are:

[0017] The triple shock absorption system—combined with the base frame's shock-absorbing grooves and feet, the storage mechanism's anti-collision and cushioning cotton, and the sealing mechanism's compressed sponge—effectively prevents vibration damage. Precise insertion of the rods and holes, along with the alignment of the limiting grooves and shock-absorbing feet, enhances the stability of multi-layer stacking. A rotary locking mechanism enables quick locking and unlocking for convenient operation. A foldable handle accommodates both handling and stacking needs, and the overall structure meets the requirements for safe transport of high-precision circuit boards.

[0018] This circuit board conveying and transfer device has the advantages of multi-layer independent storage and isolation, comprehensive shock absorption and protection, precise stacking and positioning, convenient locking operation, and flexible handling and storage.

[0019] Based on the above technical solution, the present invention can be further improved as follows.

[0020] Furthermore, the top of the transfer tray is provided with a placement groove, the side wall of the placement groove is fixedly connected with a ring-shaped anti-collision cotton, the bottom wall of the inner cavity of the placement groove is fixedly connected with a cushioning cotton, and the bottom of the transfer tray is fixedly connected with a pressed sponge. Any transfer tray can be interchanged and combined to improve the versatility and ease of replacement of the modular unit.

[0021] The beneficial effects of adopting the above-mentioned further solutions are that the placement slot can accurately position the circuit board and avoid horizontal displacement during transportation; the annular anti-collision cotton can buffer the collision force between the side wall of the circuit board and the slot body and prevent edge bumps; the buffer cotton provides flexible support for the bottom of the circuit board and weakens the vertical vibration impact; the bottom pressing sponge can fill the gap between adjacent transfer trays and prevent the upper transfer tray from squeezing and damaging the lower circuit board, thus achieving multi-layer independent isolation protection.

[0022] Furthermore, the bottom of the chassis is fixedly connected with four shock-absorbing feet arranged in a rectangular array. The shock-absorbing groove is used to collect the pressed sponge at the bottom of the transfer tray, and the pressed sponge is squeezed by the shock-absorbing groove to form a shock-absorbing layer.

[0023] The beneficial effects of adopting the above-mentioned further solutions are that the rubber shock-absorbing feet can directly reduce the vibration transmission between the transfer device and the ground or conveying equipment, while also having anti-slip properties to prevent the device from sliding; the shock-absorbing groove squeezes and presses the sponge to form an elastic shock-absorbing layer, which together with the shock-absorbing feet forms a double shock-absorbing structure, greatly reducing the vibration intensity during the transfer process and protecting the circuit board solder joints and lines.

[0024] Furthermore, the closing mechanism also includes a storage slot on the top of the cover plate, and a handle that can be folded inside the storage slot is rotatably connected to the inside of the cover plate.

[0025] The advantages of adopting the above-mentioned further solution are that the foldable handle can be unfolded when it is needed for handling, making it convenient for operators to grab without the need for external tools; when not in use, it can be folded and stored in the storage slot, avoiding the handle protruding and affecting the stacking flatness of multiple sets of devices, thus balancing the convenience of handling and the stability of stacking.

[0026] Furthermore, the top of the cover plate has four limiting grooves that are adapted to the four shock-absorbing feet respectively. The limiting grooves are used for limiting the stacking of multiple sets of equipment. Both the shock-absorbing feet and the limiting grooves are L-shaped. The shock-absorbing feet are made of rubber. The bottom of the cover plate is also fixedly connected with a pressed sponge.

[0027] The beneficial effects of adopting the above-mentioned further solution are that the L-shaped shock-absorbing feet and the limiting groove are precisely matched, which can realize the rapid alignment and stacking of multiple sets of transfer devices and prevent horizontal displacement or tipping during stacking; the rubber shock-absorbing feet can buffer the hard contact between the upper and lower devices during stacking; the pressing sponge at the bottom of the cover plate is attached to the top of the circuit board in the top transfer tray to form top protection and prevent the cover plate from squeezing and damaging the circuit board when closing.

[0028] Furthermore, the locking mechanism includes a rotating block, which is rotatably connected to the inside of the insertion rod. The top of the rotating block is fixedly connected to a rotating shaft that is rotatably connected to the insertion rod and extends above the insertion rod. The top of the rotating shaft is fixedly connected to a locking block, and the outside of the locking block is fixedly connected to a locking plate. The top of the locking block has an adjustment groove arranged in a straight line, and the slot is arranged in a stepped shape.

[0029] The advantages of adopting the above-mentioned further solution are that the rotating block and the rotating shaft cooperate to ensure the stable rotation of the locking mechanism; the straight adjustment groove can be rotated by a screwdriver or manually, making it easy to operate; the stepped slot engages with the locking plate, and can be locked by rotating 90 degrees and unlocked by rotating in the opposite direction. Compared with the traditional bolt fixing method, it greatly improves the locking and unlocking efficiency, while the locking firmness is high, preventing the cover plate from falling off during transportation.

[0030] Furthermore, the top of both the transfer tray and the cover plate is provided with four insertion holes that are adapted to the insertion rod and the locking mechanism. The slot is located above the insertion hole on the top of the cover plate and communicates with the top insertion hole.

[0031] The beneficial effects of adopting the above-mentioned further solutions are that the sockets ensure the precise insertion of the base frame, storage mechanism, and closing mechanism, avoiding misalignment during assembly; the slots are connected to the sockets, allowing the locking plate of the locking mechanism to pass smoothly through the sockets and into the slots, ensuring smooth locking action; at the same time, the limiting effect of the sockets on the plug rods can enhance the stability of the overall structure and prevent relative shaking of the components.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] In the embodiments, by Figure 1-7The present invention provides a transfer device for conveying circuit boards. The present invention includes a base frame 1, a set of storage mechanisms 2 inserted into the top of the base frame 1, a closing mechanism 3 inserted into the top of the storage mechanism 2, and four locking mechanisms 4 that engage with the closing mechanisms 3 on the top of the base frame 1.

[0042] The base frame 1 includes a chassis 101, and four rods 102 arranged in a rectangular array are fixedly connected to the top of the chassis 101. The top of the chassis 101 is provided with a shock-absorbing groove 103 that is adapted to the storage mechanism 2.

[0043] A set of storage mechanisms 2 includes three transfer trays 201, which are used to store circuit boards.

[0044] The four locking mechanisms 4 are rotatably connected to the top of the four insert rods 102 respectively;

[0045] The closing mechanism 3 includes a cover plate 301, and the top of the cover plate 301 has four slots 302 that are adapted to the locking mechanism 4.

[0046] The slot 302 is used to close the top of the storage mechanism 2 with the cover plate 301 after the locking mechanism 4 is rotated ninety degrees;

[0047] The top of the transfer tray 201 is provided with a placement groove 202. The side wall of the placement groove 202 is fixedly connected with a ring-shaped anti-collision cotton 203. The bottom wall of the inner cavity of the placement groove 202 is fixedly connected with a cushioning cotton 204. The bottom of the transfer tray 201 is fixedly connected with a compression sponge 205. Any transfer tray 201 can be interchanged and combined to improve the versatility and ease of replacement of the modular unit.

[0048] The placement slot 202 can accurately position the circuit board and avoid horizontal displacement during transportation; the annular anti-collision cotton 203 can buffer the collision force between the side wall of the circuit board and the slot body and prevent edge bumps; the buffer cotton 204 provides flexible support for the bottom of the circuit board and weakens the vertical vibration impact; the bottom pressing sponge 205 can fill the gap between adjacent transfer trays 201 and prevent the upper transfer tray 201 from squeezing and damaging the lower circuit board, so as to achieve multi-layer independent isolation protection;

[0049] The bottom of the chassis 101 is fixedly connected with four shock-absorbing feet 104 arranged in a rectangular array. The shock-absorbing groove 103 is used to collect the pressed sponge 205 at the bottom of the bottom transfer tray 201. The shock-absorbing layer is formed by squeezing the pressed sponge 205 through the shock-absorbing groove 103.

[0050] The rubber shock-absorbing feet 104 can directly reduce the vibration transmission between the transfer device and the ground or conveying equipment, while also having anti-slip properties to prevent the device from sliding; the shock-absorbing grooves 103 compress and press the sponge 205 to form an elastic shock-absorbing layer, which together with the shock-absorbing feet 104 forms a double shock-absorbing structure, greatly reducing the vibration intensity during the transfer process and protecting the circuit board solder joints and lines.

[0051] The closing mechanism 3 also includes a storage slot 305 opened on the top of the cover plate 301, and a handle 304 that can be rotatably connected to the inside of the cover plate 301 and can be folded inside the storage slot 305.

[0052] The foldable handle 304 can be unfolded when it is needed for handling, making it easy for operators to grab without the need for external tools; when not in use, it can be folded and stored in the storage slot 305 to prevent the handle 304 from protruding and affecting the flatness of the stacking of multiple devices, thus balancing the convenience of handling and the stability of stacking.

[0053] The top of the cover plate 301 has four limiting grooves 303 that are adapted to the four shock-absorbing feet 104 respectively. The limiting grooves 303 are used for limiting the stacking of multiple sets of equipment. Both the shock-absorbing feet 104 and the limiting grooves 303 are L-shaped. The shock-absorbing feet 104 are made of rubber. The bottom of the cover plate 301 is also fixedly connected with a press sponge 205.

[0054] The L-shaped shock-absorbing feet 104 are precisely matched with the limiting grooves 303, which can realize the rapid alignment and stacking of multiple sets of transfer devices and prevent horizontal displacement or tipping during stacking; the rubber shock-absorbing feet 104 can buffer the hard contact between the upper and lower devices during stacking; the pressing sponge 205 at the bottom of the cover plate 301 is attached to the top of the circuit board in the top transfer tray 201 to form top protection and prevent the cover plate 301 from squeezing and damaging the circuit board when closed.

[0055] The locking mechanism 4 includes a rotating block 401, which is rotatably connected to the inside of the insertion rod 102. The top of the rotating block 401 is fixedly connected to a rotating shaft 402 that is rotatably connected to the insertion rod 102 and extends above the insertion rod 102. The top of the rotating shaft 402 is fixedly connected to a locking block 403. The outside of the locking block 403 is fixedly connected to a locking plate 404. The top of the locking block 403 is provided with an adjustment groove 405 that is arranged in a straight line, and the slot 302 is arranged in a stepped shape.

[0056] The rotating block 401 and the rotating shaft 402 cooperate to ensure the stable rotation of the locking mechanism 4; the straight adjustment groove 405 can be rotated by a screwdriver or manually, making it easy to operate; the stepped slot 302 engages with the locking plate 404, and can be locked by rotating 90 degrees and unlocked by rotating in the opposite direction. Compared with the traditional bolt fixing method, it greatly improves the locking and unlocking efficiency, and at the same time, the locking is strong and prevents the cover plate 301 from falling off during transportation.

[0057] The top of both the transfer tray 201 and the cover plate 301 is provided with four insertion holes 5 that are adapted to the insertion rod 102 and the locking mechanism 4. The slot 302 is located above the insertion holes 5 on the top of the cover plate 301 and is connected to the top insertion holes 5.

[0058] The insertion hole 5 ensures the precise insertion of the base frame 1, storage mechanism 2, and sealing mechanism 3, avoiding misalignment during assembly; the slot 302 is connected to the insertion hole 5, allowing the locking plate 404 of the locking mechanism 4 to pass smoothly through the insertion hole 5 and engage with the slot 302, ensuring smooth locking action; at the same time, the limiting effect of the insertion hole 5 on the insertion rod 102 can enhance the stability of the overall structure and prevent relative shaking of the components.

[0059] Working principle:

[0060] Step 1: Align the four insertion holes 5 of the bottom transfer tray 201 with the four insertion rods 102 of the base frame 1, and slowly lower it so that the compression sponge 205 at the bottom of the bottom transfer tray 201 is fully embedded in the shock-absorbing groove 103 of the base frame 101; place the circuit board to be transferred into the placement groove 202 of the bottom transfer tray 201, ensuring that the bottom of the circuit board is in contact with the cushioning cotton 204 and the side wall is in contact with the anti-collision cotton 203; stack the other two transfer trays 201 in the same way, and the adjacent transfer trays 201 are isolated and cushioned by the bottom compression sponge 205;

[0061] Step 2: Align the insertion hole 5 of the cover plate 301 with the insertion rod 102 above the top transfer tray 201, and lower the cover plate 301 until the pressing sponge 205 at its bottom adheres to the top of the top circuit board; use a screwdriver or fingernail to insert into the adjustment groove 405 of the locking block 403, rotate it ninety degrees in the corresponding direction, and drive the locking plate 404 to snap into the stepped groove 302 of the cover plate 301, thus completing the locking of the four locking mechanisms 4 and realizing the closure of the storage mechanism 2;

[0062] Step 3: When transporting a single device, unfold the handle 304 inside the storage slot 305 of the cover plate 301 and use the handle 304 to transport the device; when stacking multiple sets, align the L-shaped shock-absorbing feet 104 of the chassis 101 of the next set of devices with the L-shaped limiting slots 303 of the cover plate 301 of the previous set of devices, and lower it until the shock-absorbing feet 104 are fully embedded in the limiting slots 303 to complete precise stacking; after the transport is completed, rotate the locking block 403 in the opposite direction to unlock it, and remove the cover plate 301 and each transport tray 201 in sequence to take out the circuit board.
